Technical field

The present invention relates to a kind of electronic installation, described electronic installation has following function: receive radio signals, send the information (comprising temporal information) of regulation and show or provide the notice of relevant shown provisioning information and described temporal information is corrected into correct time information.Specifically, the present invention relates to a kind of electronic installation, wherein use the metal package parts,, and have improved radio signal receptivity as metal shell.

In addition, more specifically say, the present invention relates to a kind of electronic installation, described electronic installation is configured to,, or is placed in the middle of the metal package parts even make that resonant antenna is near the metal object, its antenna performance that receives radio signals can variation yet, perhaps more particularly, the present invention relates to a kind of radio controlled time meter, antenna wherein is arranged in the middle of the metal package parts.

Background technology

In the last few years, many electronic installations appear on the market, as table, mobile phone, radio communication equipment etc., these electronic installations receive the long wave standard radio signal of telecommunication, comprise time code in the described standard radio signal of telecommunication, these electronic installations have the radio signal calibration function, promptly regulate the time of the time holding circuit in the described electronic installation during operation automatically, make it become the time of standard time.

In the past, well-known is that the form of demonstration time comprises analog form, digital form and compound mode in the wrist-watch (wrist-watch is a kind of special case of this electronic installation).Under analog form, by two or three indicator express times; Under digital form, use electric-optical appliance, as LCD or LED express time; And compound mode is the combination of above-mentioned dual mode.

With regard to these methods, in when simulation, counting, well-known also have, the user can be according to the user like selecting time meter, whether meter has second pointer or calendar during such as selection, and also can whether have second kind of such time to keep function according to time meter, as time writing function, warning function, meter when the lunar calendar deixis waits and selects.

In addition, though the precision of the electronic chronometer in past, normally determine by the precision of the circuit block in the movement (as quartz (controlled) oscillator), but, along with various countries in the last few years are used for the foundation of the transmitter of standard time radio signal, can come into operation by meter when receiving these time reference signals and carry out automatic time correction radio controlled.

With regard to the radio controlled time meter, many patent applications (disclosing No.2001-33571 as examining Japanese patent laid-open publication gazette 11-304973 and examining Japan Patent) were arranged once with regard to these.

Generally speaking, the time error that meter keeps by an internal counter in the automatic timing meter of acceptance criteria time radio signal itself when radio controlled, as long as time meter is in the environment that can receive radio signals, the index error that just might the realization table refers to very approaches 0.Set up the form of the frequency and the data of standard time radio signal by launch facility, current, except that Japan, such emission is all arranged such as the Germany and the U.S., count being widely used for these countries when radio controlled.The radio signal of using in the current radio-controlled timepiece is a long-wave signal, because it just can cover vast zone with little launch facility.And then, in Japan, for fear of the borderline interference between the standard time radio signal, two different frequencies of transmitting station emission of current Japan: 40 KHz and 60 KHz.

The problem of running into is described below over, for example, gets a time meter with radio signal calibration function when radio controlled (call in the following text meter), this is a typical electronic device.

Specifically, known radio controlled time meter, acceptance criteria radio signal as previously discussed, this is a kind of standard radio signal of telecommunication (carrier wave) that comprises temporal information, and from radio signal extracting time information, thereby can obtain precise time.For different countries, the Radio Signal Frequency that comprises temporal information is different, and for example, just like above-mentioned Japan, under the management of " general affairs portion " and " the Postal Service Ministry ", the standard radio signal of telecommunication of emission is 40 KHz and 60 KHz.

Figure 20 is a this general function calcspar of counting a kind of special case when radio controlled of expression.This radio controlled time meter is by antenna 1, meter 2, CPU3, display driving part 4 when radio controlled, and formation such as input equipment 5.

In addition, though not shown, meter also comprises hour hands, minute hand and second hand when this, perhaps adopts the display part of liquid one shroud of gas or analog.

In this radio controlled time meter, at first receive the radio signal that comprises temporal information by antenna 1.

The radio signal that receiver 2 amplifies and detection is received by antenna 1 of meter when radio controlled, and from radio signal, extract and output time information.According to the temporal information of receiver 2 outputs of radio controlled time meter, the time data that CPU3 output is current.According to the current time data of CPU3 output, display driving part 4 makes the display part show the current time.Input equipment 5 is such as being used for to CPU3 input operation information, as resets etc.

The temporal information (time code) that is included in the radio signal is to be 60 seconds pulse signal in the cycle, though it is different for this pulse signal of country variant (as Japan), but an always stacked pulse on this periodic signal, this has each second is any pulse duration in the middle of 200,500,800 milliseconds.The combination of these pulses can obtain 60 seconds time.CPU3 can obtain temporal information (current time) by read the pulse duration of heavy this pulse in per 1 second from the pulse signal that receives.The time information generating that CPU use to obtain is through time that display driving part 4 shows on the display part.Therefore, meter can be proofreaied and correct the time of each official hour demonstration at interval according to the temporal information that receives when radio controlled, thereby can show the time exactly always.

The wrist-watch that has had now be antenna is installed in the shell of closed antenna, meter, CPU, display driving part and display part when radio controlled.For making antenna can receive radio signal, the material that shell uses is electrically non-conductive material normally, as synthetic resin or pottery.In other words, if antenna is contained in by electric conducting material, in the shell such as the metal manufacturing, near the magnetic flux that produces antenna will be absorbed by electric conducting material, hinders the generation of resonance phenomena, causes the remarkable variation of receptivity of antenna.

Figure 35 represents to count when analogue type is radio controlled the general structure of another special case.

Specifically, in Figure 35, the antenna that label 101 representatives receive radio signals, label 102 is the watch movements that drive pointer, and label 103 is the shells that hold watch movement 102 and antenna 101, and label 104 is bonnets, label 105 is the dial plates with express time scale, and label 106 is a glass.

In Figure 35, antenna 101 is to form by the antenna core 101a with high permeability (as magnetic ferrites magnet or non-crystaline amorphous metal) and around the coiler part 101b that antenna core 101a twines, and with described antenna 101 in watch movement 102 is placed on the enclosure space 107 that is formed by shell 103, bonnet 104 and dial plate 105.

In this time meter, when the radio signal 109 of passing shell 103 arrives and passes antenna core 101a, in coiler part 101b, produce electric current.As the circuit module (not shown) of watch movement 102 parts and the coiler part 101b two ends electric coupling of antenna, the electric current that the coiler part 101b of antenna produces sends to a circuit through this coupling.The electric current that sends to described circuit produces resonance, and resonance frequency pre-determines with the standard time radio signal and be identical by the frequency of quartz resonator filtering, therefrom only extracts described temporal information by the decoding circuit (not shown).

In this case, watch movement 102 has counter in its Circuits System, is used for the time to keep, and this time is what to be separated with above-mentioned temporal information.Watch movement 102 relatively meets the time of described time maintenance counter and the temporal information of filtering, and, under the situation about between the two, there are differences, to motor module (not shown) output pointer correction instruction, motor is rotated, pointer is corrected to temporal information from the standard time radio signal.By such course of action, at the time point that receives the standard time radio signal, the time adjustment that will be shown by time meter is to the correct time.

Yet antenna 101 among Figure 35 and watch movement 102 all are accommodated in the enclosure space 107 that is surrounded by shell 103, bonnet 104 and dial plate 105, and antenna 101 can only receive external radio signal 109 in this enclosure space 107.

For this reason, in Figure 35, the material that forms shell 103 and bonnet 104 has higher eddy current loss, and this material just typical case is a high-polymer resin.Like this, radio signal 109 just can arrive at the antenna 101 that is contained in the enclosure space 107, can not decayed by shell 103 and bonnet 104.

Yet, forming by high-polymer resin under the situation of shell 103, to compare with the metal that in general wristwatch, uses such as stainless steel or titanium, there is tangible loss the hardness aspect.For this reason, in order to prevent during normal use must to make the thickness of the material thickness of shell 103 and bonnet 104 greater than shell that is formed by metal and bonnet because wrist-watch falls breaking of causing, this causes wrist-watch itself to become big problem.

Figure 36 illustrates for the improved previous example of above-mentioned situation.Figure 36 represents the plane graph of previous improvement example, wherein, about with Figure 35 in identical parts designated with identical label, and no longer they are described at this.As shown in figure 36, this is a kind of structure of commodity production, shell 103 wherein and bonnet 104 are formed by metal, and antenna box 110 is made by high-polymer resin, described structure is fixed on its parts, these parts and metal shell 103 and bonnet 104 are stacked not according to plane relation, thus, the antenna 101 of sealing are coupled on the watch movement 102.For this product, because antenna 101 is arranged on the outside of enclosure space 107, enclosure space 107 is formed by shell 103, bonnet 104 and dial plate 105, trend towards not being subjected to metal parts so incide the radio signal of antenna 101, such as the influence of shell 103, therefore might receive radio signal 109.

Yet in this case, the shape of terminal hour meter is very special, and existing problem is seriously to have limited meter design when final.

In addition, because shell outer 103 and antenna box 110 are made by high-polymer resin, and in shell 103 and antenna box 110, also sealed antenna, the texture of shell 103 and antenna box 110 is very big, so be difficult to adapt with design, existing thus problem is that its design becomes the design that is difficult to for user's reception inevitably.

In addition, for the situation that shell 103 and bonnet 104 are made by high-polymer resin, its shortcoming is to compare the texture variation of texture with metal.Though, may realize metallic luster by carrying out surface treatment to high-polymer resin, compare with metal, still there is undeniable deficiency aspect the texture of gloss and texture.

Though a kind of useful especially product is correspondingly arranged with the above, wherein as shown in figure 35, has only the direct visible part of dial plate 105 1 side users, frame 111 is made by metal promptly, and the shell 103 of its side and bonnet 104 are all formed by high-polymer resin, meter is compared when having metal package parts general, and the gross thickness of meter increases the texture variation of texture to some extent when final.For high-polymer resin, for example because fastening bonnet 104, might produce the tendency of plastic deformation, therefore, existing problem is, the water-stop at the junction surface between bonnet 104 and shell 103 exists a problem to be in addition, can not be included in diver's wrist-watch with high water resistance the time meter product group in.

Though correspondingly have a kind of product of reality with the above, shell wherein and bonnet are to be formed by the material except that high-polymer resin, nonmetallic materials as ceramic-like, this need carry out sintering, to keep the rigidity of pottery, existing problem is, can not realize processing accurately behind sintering, can not be polished to complicated shape in other words.Therefore, the design for external component has serious restriction.In addition, because the fragility of pottery, the problem of existence is exactly, can because of impact cause cracked with break.

Problems for fear of more so relevant antennas receptions, use not only causes anti-the suffering damage of performance and resist chemical performance of damaging by the shell of synthetic resin manufacturing, and the required attracting outward appearance that has of annex of meter and strong texture also suffer damage when also causing.For this reason, a kind of meter when having metal shell radio controlled is proposed.

Figure 21 is a profile, represents a radio-controlled timepiece example of structure, and wherein, the part shell uses metal.The shell 10 of this wrist-watch generally includes: main body 11, bonnet 12 and the shielding 13 of keeping out the wind.Watch movement 14 is arranged in the main body, and main body is connected on the watchband by well-known device.Dial plate 15 and indicator 16 also by well-known device be arranged in watch movement 14 above.Stick antenna 17 is long wave magnetic antennas, with stick antenna 17 be located at watch movement 14 below, thereby be positioned at the top of bonnet 12.Described stick antenna 17 is to form by core components 18 with around the coil 20 of core components 18, and is fixed on the upper surface of the hold assembly of being made by synthetic resin.

Watch movement 14 has: just like above-mentioned radio controlled wrist-watch receiving system, CPU and display driving part, watch movement 14 is electrically coupled to stick antenna 17 by conductor 21.Therefore, according to the standard radio signal of telecommunication that stick antenna 17 receives, the CPU of watch movement 14 moves the gear mechanism (not shown) in the display driving part, thereby drives the position of the pointer 16 of display part, thereby constantly proofreaies and correct these pointers.In this specification, get upper and lower to the upper and lower of expression among Figure 21 to.

With non-hollow, promptly solid electric conducting material is made main body 11 such as solid stainless steel.Make paravent by glass and cover 13, glass is a kind of electrically non-conductive material, utilizes known means, and the shielding 13 of will keeping out the wind is fixed to the most external of main body 11 as binding agent or analog.Make dial plate 15 by electrically non-conductive material synthetic resin or pottery.Utilize annular peripheral framework 22 to form shell bonnet 12, it is made by stainless steel, and is fixed on the main body 11, and glass 23 is fixed to the inboard of peripheral frame 22.In this manner, though electrically non-conductive material can be seen in the upper and lower surface in the main body of this wrist-watch, because the lateral parts of shell is made of metal, its advantage is to sacrifice the attracting outward appearance of time meter annex and stronger texture (such as with reference to examining the open No.2001-33571 of Japan Patent).

Specifically, picture is adopted at the open No.2001-33571 of not careful Japan Patent, making under the situation of bonnet with non-conducting material (usually such as high-polymer resin, glass or pottery), though have above-mentioned advantage, but selecting to also have many restrictions aspect the material, also have any problem at manufacture view, and also have many problems aspect the outward appearance that realizes the pleasant of meter when final, therefore expectation forms metal shell bonnet.

For these reasons, develop timing when radio controlled in the past, for the material of external component very big restriction is arranged, in other words, make that the meter microminiaturization is extremely difficult when final.

In described radio controlled time meter, can think, can determine receptivity by antenna performance and receiving circuit characteristic.

This just means, current techique knowledge according to the past, the lower limit of the input signal of receiving circuit or receiving integrate circuit in fact is about 1 microvolt signal amplitude, in order to obtain actual receptivity, must obtain output signal, the amplitude of this signal is about 1 microvolt, and the electric field strength of signal receiving antenna (radio signal strength) is 40-50 decibel microvolt/rice.

For this reason, for the situation that has size restrictions, use can realize the mode of resonance antenna than large-signal output usually.

Because radio signal is the long wavelength's, uses around magnetic core usually and twine the stick antenna of lead as such antenna.

In such reception antenna, because the output of reception antenna is proportional to the size of reception antenna in fact, in order to obtain in fact available receptivity, antenna can not be egregiously little, and this causes such as wrist-watch this receptivity of coming meter when small-sized and the problem of receiving position aspect.

In addition, when reception antenna being contained in the metal package parts, the output of reception antenna descends sharp.

For this reason,, must have the modular construction or the design that are different from past tense meter modular construction fully in the wrist-watch, in addition, also must consideration can not hinder receptivity in order to utilize radio signal.

For wrist-watch, important project be in light weight, approach, be easy to carry, the texture good (high-quality sensation) of design freedom height, texture, and expect to have a built-in aerial unit and metal package parts.

As previously discussed, meter during past radio controlled, main method is externally the enclosure space mounted antennas or the antenna of packing into.

For the situation that the material of bonnet and sidewall is metal, generally all reception antenna is installed in the outside.

In this case, because the antenna box of reception antenna made as plastics by nonmetal, in order that be unlikely the reduction receptivity, so, this antenna box is exactly a big protuberance form, thereby causes compactedness, thinness and portability, and design freedom all is subjected to extensive damage.

For reception antenna is built-in situation, though use pottery or plastics as the time meter the material of external component (bonnet and sidewall), so that do not reduce receptivity, but the intensity of these materials is low, the thickness of table is increased, thereby, can sacrifice storageability and portability, produce very big restriction for design.

In addition, the result of gained is the texture what external texture wrist-watch does not have.

For this reason,, such situation is arranged, a metal antenna promptly is set in the belt of wrist-watch such as what can see among the open No.2-126408 of Japanese unexamined patent publication No..

In addition, as disclosed meter when a kind of in the open No.5-81787 of Japanese unexamined patent publication No., wherein, dial plate and keep out the wind the shielding between an antenna is set, the coil of this antenna twines around a magnetic core, not only from disturb the radio signal can, remove described antenna, but also a kind of unique design is provided.In addition, disclose a kind of wrist-watch in International Patent Application WO 95/27928, in the structure of this wrist-watch, antenna is installed in the sidepiece of watchcase.

In addition, disclose disclosed a kind of time meter in 0382130, wherein, antenna is located on the upper surface such as shell, circularize shape such as European patent.

Yet, in the structure that in the past antenna is arranged in the watchband,,,, can not give enough big flexibility for bonding part between the two so must be electrically connected with electronic installation itself because antenna is located in the watchband.

In addition, because can not use the metal watchband that can disturb radio signal, therefore must use special watchband, this has just produced restriction to material and design.

Have again, when antenna is located at the upper surface of meter or be located at time meter side surface the time meter in because the metal part of antenna meter when having left itself, so have the thickness of meter when whole or the problem of size increase, this has produced restriction to design.

In addition, European patent discloses and discloses a kind of time meter in 0382130, wherein, antenna is located on the upper surface of shell, becomes annular shape.The problem that meter exists when such is, if in annular section, there is metal owing to can not receive, then must provide in fact with the time score antenna opened.

In addition, though the open No.11-064547 of Japanese unexamined patent publication No. discloses meter when a kind of, coil wherein is located at the recessed portion in the circuit board peripheral part, and magnetic core is arranged on along in the sweep of printed circuit board (PCB) circumferencial direction.But this will cause following problem: complicate fabrication process not only, and in manufacture process, be difficult to assembling.

In publications such as open No.2001-33571 of Japanese unexamined patent publication No. or the open No.2001-30524 of Japanese unexamined patent publication No., all represented the structure of meter when a kind of.Wherein, keep out the wind shielding and the back cover portion of time meter be by making such as nonmetallic materials such as glass or potteries, the time meter mid portion make by metal material, just as the wrist-watch in past, so have abundant radio signal can arrive at antenna.

The open No.2001-208875 of Japanese unexamined patent publication No. disclose a kind of technology, it with the time identification mark counted relevant.The basic fundamental of the recognition system that is disclosed is composed as follows: when climbing up a skiing elevator or analog, an identification mark is provided in the wrist-watch that the user held, and with the recognition device exchange identification mark that is located on the elevator door in information, thereby can determine whether the user is a passenger who is authorized to.

Yet, in this patent publications, the basic ideas that this technology is formed are from the very strong high frequency radio signal of recognition device emission, and the wrist-watch with identification mark is caused near it, thereby the integrated circuit in the excitation wrist-watch is read the information of described identification mark by recognition device.

In other words, in above-mentioned publication, with being configured to of described wrist-watch, make when the antenna that provides in time meter receives high frequency radio signal, in the integrated circuit in the time of then in the meter resonance takes place, cause following result: integrated circuit receives electric power, and encourages described integrated circuit, and the identification mark information when reading in the meter is sent Wireless Note to recognition device simultaneously.

Therefore, though this patent publications provides following instruction: even, can change above-mentioned information by the work of the antenna that in wrist-watch, also has with metal package parts.Yet, with respect to the application, obvious difference aspect technical thought is: the recognition device that the emission high frequency radio signal is provided, requirement will have the close described recognition device of time meter of identification mark, the antenna that provides in time meter is based on stick antenna, so that the high frequency radio signal of recognition device emission can receive fully.And, thisly be received in the wrist-watch thinly as far as possible and big because need make, must use the square antenna of thin and straight type, these are different with the application significantly.In addition, also between antenna element and metal package parts, set up a kind of specific relation.

In addition, in the open No.57-131042 of Japanese unexamined utility model, a kind of formulation of relevant wrist-watch is arranged, wherein, provide a kind of antenna, this antenna uses annular magnetic stripe, and this annular magnetic stripe is the C shape ferromagnet around a conductor part.Yet this known example is relevant with the antenna of wrist-watch, and described wrist-watch has a wireless device, and this antenna only is arranged on the outside of wrist-watch, and antenna obviously is not set in the metal package parts.

Have again, though in the open No.6-215942 of Japanese unexamined patent publication No., for effect a kind of saying is arranged as the inductor core of discrete component, promptly relate to a kind of chip inductor, and, just the technical field aspect is obviously not different with the antenna of wrist-watch of the present invention, and aspect goal of the invention and technology formation, tangible difference is arranged also.

In the open No.11-74138 of Japanese unexamined patent publication No., though relate to a kind of transformer, dust core wherein is the combination of U-shaped parts and I shape parts; Secondary coil twines round described U-shaped parts, and what this related to is the process that obtains high-tension transformer, and is not only obviously different with the antenna of wrist-watch of the present invention aspect technical field, and aspect goal of the invention and the technology formation substantial difference arranged also.

In the same way, the open No.61-203516 of Japanese unexamined utility model discloses a kind of structure, wherein, the abutment surface of magnetic core is tilted with respect to vertical magnetic circuit direction, this relates to the process that obtains inductance element, not only aspect technical field, have significantly differently, and aspect goal of the invention and the technology formation substantial difference is being arranged also with the antenna of wrist-watch of the present invention.

In the open No.2002-184637 of Japanese unexamined patent publication No., find a kind of formulation, be tapered and change surface area about the gap that makes coil core, this known example is relevant with high-tension transformer, not only aspect technical field, have significantly differently, and aspect goal of the invention and the technology formation substantial difference is being arranged also with the antenna of wrist-watch of the present invention.

In addition, though the formulation of relevant structure appears in above-mentioned known list of references, wherein, make the magnetic core of inductor become an independent element, but this is relevant with high-tension transformer or chip inductor, not only aspect technical field, have significantly differently, and aspect goal of the invention and the technology formation substantial difference is being arranged also with the antenna of wrist-watch of the present invention.

In other words, above-mentioned each example in the past is for antenna is placed on the output of antenna is sharply reduced, so, their purposes are that by the material that makes bonnet be nonmetallic materials, slowing down sharply reducing of described output, and can adopt metal side with higher texture texture.

Yet, in above-mentioned each example in the past, owing to use glass or pottery, so the problem that exists the thickness of table to increase.

Thereby, past is owing to must use large-scale higher-sensitivity antenna structure for radio controlled time meter, perhaps owing to only may be used in the very big zone of radio field strength signal by meter when radio controlled, the feasible convenience that has lost it, therefore, can increase the manufacturing expense of antenna structure inevitably, wherein, comprise the design cost of actual antennas.

And then, in the wrist-watch of this structure, if might make radio signal arrive antenna, and bonnet is coated with the very thin coat of metal, to stay used to the user is the impression of metal material, but so, the texture texture of the weight of table and outward appearance just loses meaning, and the problem of existence is the image of counting when having lost high-quality.

In addition, because antenna is located in the metal sidewall, reduces with regard to the output that makes antenna, and make the receptivity variation.

For this reason, be difficult in the past realize having the all-metal surface part, and meter when having strong texture radio controlled.

In order to solve these problems of the prior art, the inventor has found out the problem among the Japanese patent application 2001-297095: in the time of in antenna being located at the time meter enclosure space that has metal sidewall or metal back cover, the Q value is descended, thereby cause the obvious variation with receptivity of reducing of antenna structure output.In order to address this problem, a kind of technical pattern is proposed, wherein, make antenna have special construction, thus make antenna structure Q value reduce as far as possible for a short time, whereby, can prevent the decline of the receptivity of antenna.

Yet, antenna is had in the method for special construction, we understand, improvement to the antenna structure receptivity is conditional, as the result who further effectively investigates, we also understand, and comprise the structure or the characteristic of the metal package parts of antenna structure terminal by regulation, can further improve above-mentioned problem.

In addition, result as effective investigation, verified: with regard to thinking in the past, make the metal object with conductivity and the antenna element that is used for receiving radio signals near or situation about contacting under, radio signal is absorbed by metal object, radio signal does not reach antenna element, therefore the output of the resonance of antenna element reduces, and such as the Q value is descended, in fact, the understanding of past to this problem is wrong.And confirm: even under the situation of the metal object with conductivity near to or in contact with antenna element, radio signal has in fact arrived antenna element, and under the disresonance situation, because within counting when the magnetic flux flow that the external wireless electric wave produces is just being attempted to enter, certainly wherein some decay (such as about 3 decibels), radio signal has in fact unhinderedly arrived antenna.

Obviously, the problem that occurs during antenna resonance is: the magnetic line of force (magnetic flux) that sends from the magnetic core of antenna element is drawn in the metal object, and the magnetic line of force wherein causes eddy current, and eddy current makes the magnetic energy decay, thereby the problem that causes antenna element output to reduce, but also hindered normal reception.

In other words, when the control of as shown in figure 21 existing radio in the meter, when using, though there is not the problem of big radio signal receptivity aspect in portable mode.Yet because glass 23 is fixed on the peripheral frame 22 of bonnet 12, in case impacted because of falling such as wrist-watch, the problem of appearance can be that glass 23 breaks.In addition, because bonnet 12 closely contacts with wrist, in long-term use, sweat and analog may make glass 23 fall down from peripheral frame 22, therefore, exist sweat, moisture content, dust etc. may invade the obvious danger of watch movement (antenna 1, radio controlled wrist-watch receiver 2, CPU3, display driving part 4 etc.), the function of wrist-watch is obviously reduced.

In addition,, except that having increased part count, also there is a problem, promptly increased the number of steps of assembling, and increase cost because bonnet 12 is provided with glass 23.Because external component uses nonmetallic materials, make wrist-watch lack weight sensation, will have problems aspect high-quality sensation and the noticeable sensation.

Consider above-mentioned prior art problem, produce the present invention.The present invention aims to provide a kind of electronic installation, even this electronic installation also can receive the information of regulation for the metal shell of routine, such as temporal information, does not also have any problem when using in portable mode.And this electronic installation also has the quality of waterproof, not only can improve presentation quality, variation that can also expansion design, and the mode of expansion is identical with the time meter of universal class.

In addition, as one object of the present invention, be will provide to solve a kind of electronic installation of the problems referred to above in the past, described electronic installation has good radio signal receptivity, and has the metal package parts.One antenna element wherein is set, and this antenna element can not face restriction aspect material, and can not face restriction at design aspect yet.

Except above-mentioned purpose, in the time of on the present invention being applied to radio controlled time meter, wherein, described when radio controlled meter just apply the present invention to particular example on the electronic installation.Another object of the present invention is, not only can avoid causing because of the increase of thickness the increase of wrist-watch volume, and a kind of meter when having good feel radio controlled on wrist of wearing can also be provided.

In addition, similar with time meter in the past, the invention provides a kind of radio controlled time meter, though this radio controlled time meter adopts by titanium or stainless steel metal package parts and metal back cover that make and that high magnetic permeability is arranged, but can keep and make the identical receptivity of receptivity of shell and bonnet, and be compact and slimming by high polymer or pottery.

In this special case, can also in gap 55, insert above-mentioned insulator.

Described gap 55 is not limited to position as shown in Figure 7, and has as previously discussed, obviously gap 55 can be applied to have in the metal package parts 31 any position that at least two metal partss of any connected structure that forms are bonded with each other.

In order to confirm the above, provide experimental result shown in Figure 31.

In experiment shown in Figure 31, under two selected frequencies, measure the characteristic value of each antenna, a kind of situation is not form gap 55 (experiment 1: non-incision) in the back cover part 41 of the metal package parts 31 with loop configuration and the attachment 39 between the main element 45, second kind of situation is to provide gap 55 (experiment 2) near antenna the attachment 39, and the third situation is that gap 55 (experiment 3) is provided in the part attachment 39 of the opposite side of antenna.

Can judge from experimental result shown in Figure 31, will be understood that, though there is no big difference in antenna features and gap 55 position related aspects, but provide two kinds of situations of cut-away portions to show: the gain effect with situation of otch is better than not providing the situation of otch, promptly is better than the situation of very close to each other 55 structure.

Below, describe insertion type insertion parts 49 in the metal package parts 31 be located at electronic installation 30 or the two in gap 55 or these parts in detail and concern with position between the antenna 32 that is located in the metal package parts 31.

At first, though the structure of the antenna 32 that uses for the present invention does not have special restriction, but shown in Fig. 1-7, can wish that described antenna is the coil that twines around a straight or crooked magnetic core, the maximum longitudinal length of magnetic core is less than the diameter of metal package parts 31.

Certainly, in the present invention, magnetic core can be shape annular or loop, and can be to have the antenna 32 of structure as shown in figure 14.

In the present invention, as previously discussed and shown in Fig. 4-7, can wish antenna 32 is located near the neighboring of metal package parts 31, specifically, be exactly near above-mentioned attachment 39.

Antenna 32 is being located under the situation of metal package parts 31 inside, in fact antenna 32 can be located near any position the neighboring part of attachment 39 of metal package parts 31.

In order to realize purpose of the present invention best, as above special case is described, can wishes antenna 32 is located at and be used to be provided with near the position in insertion type insertion parts 49 or gap 55.

Specifically, as shown in Figure 6, in the attachment 56 that surround by fan section 57, form the insertion type insertion parts 49 or the gap 55 of metal package parts 31 continuously; Shown in the label 60 among Fig. 8 (A), be that discontinuous ground forms perhaps.Described fan section 57 is that the core by two ends of the magnetic core of the antenna 32 with specific length and metal package parts 31 forms, and makes the antenna 32 that is provided near the position that insertion type insertion parts 49 or gap 55 are provided.

Because the length in fan section 57 is to be determined by the position that is provided with of the magnetic core length A of antenna 32 and antenna 32, therefore can wish to make the position that is provided with of antenna 32 to be in the scope by ratio (B/A) representative of the magnetic core length A of antenna 32 and the angle between the attachment 39.

The location of Figure 32 (A) expression antenna 32 in metal package parts 31.The length in Figure 32 (B) expression gap 55 and the relation between the described angle, the length in described gap 55 promptly is: the length B in the fan section 57 under the situation that the antenna 32 with specific length A begins to move along the direction in gap 55 from the core of metal package parts 31.The length B in Figure 32 (C) expression fan section 57 and an example of the ratio of the length A of antenna 32.

From being appreciated that in essence for the situation that contact point is not provided in the fan section, and the central angle scope in the expection fan section is that described angle must be 0.64-2.5 than (B/A) under 30-180 ° the situation; And under identical condition, can expect that central angle scope in the described fan section is that then described angle must be 1.05-2.16 than (B/A) under 50 °-120 ° the situation.

In addition, the central angle in the fan section is 10 ° or it when following, is appreciated that under the situation that contact point is not provided in the fan section that described angle must be 0.21 or littler than (B/A).

Therefore, the data of blanket Figure 32 (C) and the relevant preferably angular range information shown in Fig. 5 (B) just can be predicted the optimum position that the antenna 32 of specific length should be placed.

The angular range in the described fan section 57 among the present invention is 30-180 °, preferably 50-120 °, and more preferably 60-90 °.

In order to study preferable range just like fan section 57 central angles shown in Fig. 5 (A), constitute one just like the special case shown in Fig. 5 (A), and measure the condition that antenna gain (decibel) changes, simultaneously, change the central angle (θ) in fan section 57, in fan section 57, shown in Fig. 6 (A), removed thread groove like that, it the results are shown among Fig. 5 (B).

Just like what from the curve of Fig. 5 (B), can clearly find out, because the increase of removing regional perspective along with attachment in the threaded portion 39, the gain of described antenna 32 (decibel) also will increase, so, be appreciated that, in the angular range of being studied, can realize effect of the present invention, preferably 60-90 ° of this angular range.

In the special case of the present invention shown in Fig. 8 (A), in above-mentioned fan section 57, for the whole attachment 39 that form with 120 ° of central angles, the antenna features of gained under the situation that the whole thread groove that perhaps forms in the same area all removes, and be included in the part thread groove in the above-mentioned fan section 57 and therefrom do not remove and (particularly be positioned at the thread groove in the zone of determining by 10 ° of central angles in reservation, described zone is by 57 the center line from the fan section, prolong 5 ° of generations of two end margin lines respectively left and to the right) situation under the antenna features of gained, all promptly do not provide the antenna features of removing part or notch portion not being provided or in whole attachment, not inserting insertion type insertion parts 49 gained to compare with method by routine.

From this more as can be seen, though compare with the structure in past, in preceding a kind of structure, obvious effects is arranged, on the other hand, though for the structure in past, can see some effect from a kind of structure in back, but that the effect of this a kind of structure in back is compared with preceding a kind of structure is very little, but very practical.

Have as previously discussed, in the present invention, might antenna 32 be set in the position corresponding with above-mentioned fan section 57.

Subsequent, will the preferred structure of the used antenna 32 of the present invention be described.

Specifically, the used antenna 32 of the present invention is essentially stick antenna, and preferably the inductance value of described antenna is 1600 milihenries or following, and the resistance value of aerial coil is 1 kilohm or following, in addition, the number of turn that can also wish described aerial coil is 1000 or more some more.

Describe a preferred special case of antenna structure of the present invention below in detail.

Specifically, Fig. 9 represents the schematic plan view of 32 1 kinds of special cases of antenna of the present invention, and the antenna 32 shown in this figure can receive radio signals, and is set in the time meter, and meter is made of side member 44 that is made of metal and back cover part 41 when described.

In the described in the above example in the past, in having the metal package parts of metal sidewall or crown cap, be provided with under the situation of antenna, because the metal package parts have hindered the resonance phenomena that produces by means of antenna (magnetic flux change to the variation that electrical power changes to magnetic energy), specifically, be owing in metal parts, absorbed the magnetic line of force that produces by resonance phenomena, cause eddy current therein, the result who produces has consumed nearly all magnetic line of force (because iron loss), thereby the gain of antenna and Q value are greatly reduced, this demonstrates a problem implementing meter when radio controlled, and promptly antenna is in the inside of metal package parts.

Generally speaking, though along with the increase of coil turn, gain increases, and should be appreciated that, when the number of turn reached some, it is big that the resistance of coil (copper loss) becomes, and gain will reduce.

Specifically, because the output of antenna is made up of the output of resonance phenomena in output that meets faraday law and the antenna, when antenna being placed in the metal package parts,, also greatly reduce so gain because Q value obviously descends.

According to different sayings, generally, antenna is not near metal object, the nearly all gain that obtains from antenna all is because above-mentioned resonance phenomena produces, and this has just increased the coil resistance (copper loss) of aerial coil, hinders the carrying out of resonance phenomena, cause reducing of gain (Q value), so, can not use very many coil turns, perhaps can not make the line of coil meticulous.

Under the contrast, under situation about antenna being placed in the metal package parts, because iron loss (metal package parts) is very big, so reducing of Q value is very big, and reducing of gaining is very big.

For this reason, the present inventor has carried out improving the investigation of antenna gain method, wherein supposition: when antenna being placed in the metal package parts, the Q value is reduced.

Specifically, in the present invention, when antenna being placed in the metal package parts, as determining how to make the maximum result of efforts of gained gain, not only to increase but also will make to gain by faraday law fully as before by Q value (resonance).

In order to confirm above-mentioned technical thought, the inventor at first experimentizes, and measures the inductance L value (milihenry) of a specific antenna and the relation between the gain (decibel), has as shown in Figure 10.Specifically, curve A among Figure 10 is illustrated in specific antenna and is not inserted under the interior situation of metal package parts, relation between the gain (decibel) when inductance value L and reception 77.5 KHz, curve B is illustrated under the situation in the antenna insertion metal package parts 31 of same structure, the relation between the gain (decibel) when inductance value L and reception 77.5 KHz.

In this experiment, use known method that coil is wrapped on the straight magnetic core of a routine, and by changing coil turn and changing coil resistance, to regulate the variation of inductance value L.

Just like understandable, have been found that in the antenna in not being placed in the metal package parts that though gain increases along with the increase of inductance value L, when inductance value L surpassed 10 milihenries, gain was just saturated gradually from Figure 10.Yet for the antenna in being inserted into the metal package parts, above-mentioned saturated phenomenon does not occur, and gain increases with the increase of inductance value L is linear pro rata.

In other words, above-mentioned experimental result shows, though under situation about antenna being placed in the metal package parts, follow the gain of resonance phenomena to have tangible decline,, with respect to the gain due to faraday law, this is minimum pad value just.

After the other investigation of process, the inventor judges, from result shown in Figure 10, the antenna 32 that employing is used in the metal package parts, because gain is along with the increase of inductance value increases linearly, so the coil turn that can expect and inductance value L become very big.

Yet when coil turn became very big, because the electric capacity of antenna self increases, so just existence is about the restriction that resonance point added to by antenna, this produced a upper limit inevitably.

As previously discussed, the inventor judges: normally be approximately 10pF if get the capacitance of aerial coil, and because used low-limit frequency is 40 KHz, then calculate to such an extent that the inductance value L of antenna 32 is the 1584-1600 milihenry, therefore expect that inductance value is 1600 milihenries or littler from Equation f=1/2 π √ LC.

In the practice, if we consider, except that the electric capacity of aerial coil, the parasitic capacitance that also will comprise substrate and integrated circuit, and owing to be about under the situation of 20pF in the parasitic capacitance that can expect, inductance value L is confirmed as the milihenry from 792-800, therefore, can expect that using inductance value L is 800 milihenries or littler antenna.

In addition, if consider that the current actual highest frequency that uses is 77.5 KHz (Germany), and according to judging in the used hypothesis of this frequency range: the inductance value L of the antenna 32 under those situations of determining from above-mentioned capacitance and frequency may be about the 211-220 milihenry, and, it is also contemplated that and use antenna 32 with 220 milihenries or bigger inductance value L.

And then, can expect that the inductance value L lower limit of antenna 32 of the present invention is about 20 milihenries.

Though the electric capacity of receiving integrate circuit is depended in the desired minimum output of antenna, can expect that if the desired minimum output of antenna is 50 decibels, then to be expected be 25 milihenries to the inductance value L lower limit that obtains from Figure 10; If the desired minimum output of antenna is 51 shellfishes, then to be expected be 20 milihenries to the inductance value L lower limit that obtains from Figure 10, and then if the desired minimum output of antenna is 52 decibels, then to be expected be 15 milihenries to the inductance value L lower limit that obtains from Figure 10.

If consider that the inductance value L of antenna is at most the 2-13 milihenry in counting when prior art is radio controlled, can think that then being considered to preferred inductance value L in the invention described above should be a special value.

Below, we investigate the relation between coil turn (circle) and the antenna gain (decibel), the results are shown among Figure 11 of this investigation.

Specifically, among Figure 11 with Figure 10 in experiment similar, curve C is illustrated under the situation that specific antenna is not inserted into the metal package parts, when receiving 77.5 KHz, the relation between coil turn (circle) and the antenna gain (decibel); Curve D is illustrated in to be inserted the antenna with spline structure under metal package parts 31 situations, when receiving 77.5 KHz, and the relation between coil turn (circle) and the antenna gain (decibel).

Just like understandable like that from Figure 11, as can be seen, in the antenna in not being placed into the metal package parts, though gain increases along with the increase of coil turn (circle), when coil turn surpassed 1000, gain was just saturated gradually.Yet for the antenna that is inserted in the metal package parts, above-mentioned saturated phenomenon can not take place, and gain increases with the increase of coil turn (circle) is linear pro rata.

Therefore, in the present invention, can reach a conclusion, when in the middle of the sidewall of described external component and bonnet one or two is metal radio controlled in the meter, can expect that the coil turn (circle) of antenna 32 is 1000 to enclose or more some more.

In addition, just like understandable from Figure 11, use separately and be not placed under the situation in the metal package parts at antenna 32, is 1500 or more for a long time at coil turn (circle), gain saturation.Certainly, under antenna 32 is placed into situation in the metal package parts, even at coil turn (circle) is 1500 or more for a long time, gain is also increasing, when in the middle of sidewall and bonnet one or two is metal radio controlled in the meter, judge: if the coil turn of antenna 32 is 1500 or bigger, whether antenna is more effective.

But, when the coil turn (circle) of antenna when increasing, because the resistance value of antenna is also increasing, so for restriction of coil turn (circle) existence.

As above given, the inventor has finished the experiment that has as shown in figure 12, this experiment is similar with experiment as shown in figure 10, be not inserted at specific antenna and carry out this experiment under the metal package component condition, the inventor depicts when receiving the radio signal of 77.5 KHz, the relation curve E between the gain (decibel) of coil resistance (ohm) and antenna 32.

In addition, the inventor depicts and the antenna that has with above-mentioned same structure is being inserted under the metal enclosed steric requirements the same F that concerns when receiving the radio signal of 77.5 KHz.

What curve G described is the coil resistance (ohm) of antenna 32 and the relation between the gain (decibel), and the relation between coil resistance of antenna 32 (ohm) and the gain inequality, described gain inequality is meant near the gain of gained when antenna is the metal package parts and near poor between the gain of gained when antenna is not the metal package parts.

In experiment as shown in figure 12, by suitably making up the resistance value shown in Figure 12 (B), with regulating winding resistance (ohm).

Just like understandable like that, even only use not antenna 32, even and under situation about antenna 32 being arranged in the metal package parts, along with the increase of coil resistance (ohm), gain will reduce with the metal package parts from Figure 12 (A).

When observing curve G (curve G represent above-mentioned curve E and the gain inequality between the F), we can see, when coil resistance (ohm) meets or exceeds 1 kilohm, utilize the situation of metal package parts and in the metal package parts, use the gain inequality between the situation of antenna just to no longer include any variation at antenna 32, in the zone of about 3-4 decibel, described gain inequality is constant.

Different with the thinking in past, near the metal object that will have conductivity is placed on antenna, perhaps contact with antenna, so that under the situation about receiving radio signals, radio signal is absorbed by metal object, consequently radio signal does not arrive antenna, thereby has reduced the resonance output of antenna and reduced the Q value; Compare with the thinking in this past, effective finding of being undertaken by the inventor is: the above-mentioned understanding to this problem is wrong in the past, even near the metal object that will have conductivity is placed on antenna or with situation that antenna contacts under, radio signal has arrived at antenna basically, under the disresonance situation, though some decay (such as about 3 decibels) of flowing of the magnetic flux that the external wireless signal of telecommunication of meter causes when attempting to enter, but radio signal arrives antenna and is not hindered, and this point is confirmed, and meets the fact.

Problem is: when antenna resonance, the magnetic line of force (magnetic flux) that leaves antenna core is pulled metal object again, produces eddy current in metal object, thereby causes the decay of magnetic energy, has reduced the output of antenna, thereby can not receive normally.

Have been found that by means of the detailed description to the problems referred to above among Fig. 4, such as having metal and make in the metal package parts 31 of time meter 30 of bonnet and under the situation of attempting to receive radio signals in that antenna 32 being placed on, though the magnetic flux J that is caused by the radio signal of attempting to enter electronic chronometer 30 flows some decay (such as about 3 decibels), but radio signal has arrived antenna 32 and has not been hindered, antenna 32 has received the magnetic flux of radio signal, and when antenna resonance, promptly when the mutual alternative that exists between electric energy and the magnetic energy, from the resonance flux flow A of the two ends output of the magnetic core 38 of antenna 32, B, C ₀Be pulled again within the metal package parts 31, described metal package parts 31 are made by metal material, produce eddy current in metal package parts 31, cause the flow absorption of 7 energy of resonance magnetic flux thus, cause the reducing of resonance output of antenna 32.

In other words, if the characteristic value of antenna 32 is defined as the Q value, because the Q value representation is the ratio of output with the input of antenna, it is under 1 the situation that Q=100 represents to import, and output is the output characteristic of 100 this effect; The Q value is high more, and it is superior more that the performance of antenna is considered to.

In other words, the Q value is high more, and it is good more that the performance of antenna is considered to, and perhaps changes a kind of saying, and the Q value is the index of energy loss size.

A kind of special case that can be used for measuring Q value method, illustrated such as having in the specification of Japanese patent application 2002-264985, this Japanese patent application is that the inventor submits to.

From The above results as can be seen, if the value of coil resistance (ohm) is 1 kilohm or littler, owing to can expect: coil resistance is for the contribution of the gain effect of the antenna 32 that uses in the metal package parts, certainly be greater than antenna 32 and do not use under the situation of metal package parts contribution, so can expect that coil resistance (ohm) value of the antenna 32 that uses among the present invention is 1 kilohm or littler for gain.

Generally speaking, the thickness of meter is about 10mm when thinking, and at the width of aerial coil is that 20mm, coil core thickness are that the lead of 1mm, winding wire and conductor diameter are respectively that 60 microns and 65 microns, coil resistance are considered under the about 1 kilohm situation, and then 25000 circles are limits values of coil turn.

More precisely, the coil resistance of coil turn in Figure 10 data with these samples shown in Figure 13 replaced, and the data of Figure 13 and Figure 12 are combined, under the situation in antenna 32 is not placed in metal package parts 31, draw coil resistance (ohm) value and the relation curve H between the gain (decibel) of antenna 32 when receiving the radio signal of 77.5 KHz; And under the situation in antenna 32 is placed in the metal package parts, draw coil resistance (ohm) value and the relation curve I between the gain (decibel) of antenna 32 when receiving the radio signal of 77.5 KHz.

Curve E, the F of these curves H, I and Figure 12 are basic identical.

Curve J among Figure 13 be illustrated in antenna 32 be inserted in the metal package parts 31 situation lower coil resistance (ohm) value and when the radio signal of reception 77.5 KHz the relation between the gain (decibel) of antenna 32.Coil turn changes to 2000 circles from 1000 circles, and expression makes moderate progress for gain when coil turn increases.

Curve K is the curve that is fitted to curve J approx.

Curve M is as a curve, its expression since coil resistance (ohm) value increase gain that (shown in curve I) cause reduce ratio with because coil turn (circle) increases the balance between the ratio of the increase that gains due to the caused coil resistance increase.

Can clearly find out from the curve M of Figure 13, when coil resistance (ohm) during greater than about 396 ohm, the increase of described gain and reduce between balance saturated, thereby be appreciated that, increase coil resistance (ohm) and make it surpass 400 ohm, just can not reach described effect.

Therefore, the coil resistance (ohm) that can expect antenna 32 among the present invention is 400 ohm or littler.

In addition, among the present invention, under the situation of using the metal package parts, if consider the gain not only high and also have very little variation the zone in the use antenna 32 be the most effective, then can expect, and just like the curve F from Figure 12 as can be seen, can be desirably in the coil resistance (ohm) that uses antenna 32 under 100 ohm or the littler condition.

What can also expect is that the lower limit of the coil resistance of antenna 32 (ohm) is about 18 ohm.

Specifically, if the required minimum output of antenna is-51 decibels, then as can be seen from Figure 11, coil turn is 1400 circles; And for coil commonly used, its line directly is 110 microns, the conductor diameter on the antenna is that 100 microns, the width of the winding part of antenna are that the thickness of 20mm, magnetic core is 1 millimeter, and then resistance is 18 ohm; For 80 microns of 85 microns in line footpath and conductor diameters, this resistance becomes 22 ohm; For 65 microns of 70 microns in line footpath and conductor diameters, this resistance becomes 30 ohm; For 60 microns of 65 microns in line footpath and conductor diameters, this resistance becomes 38 ohm, and this resistance range is taken as limits value.

The coil resistance (ohm) of meter antenna has only about 20 ohm during prior art radio controlled, and among the present invention the numerical value of used coil resistance (ohm) significantly greater than this numerical value.

From above-mentioned experimental result as can be seen, under situation about antenna 32 being placed in the metal package parts of the present invention, even the coil resistance of antenna (copper loss) increases, reducing of Q value also is minimum, change a kind of saying, even the line footpath is very little, and the number of turn is identical, the change of Q value and gain G also is minimum.

By the increase of coil turn, the antenna gain of antenna 32 is improved.

So under situation about antenna being placed in the metal package parts, the very thin and increase coil turn of lead by making coil can improve gain.

Under the antenna 32 of prior art is not inserted into condition in the metal package parts, though having the situation of small resistance value, winding wire diameter big (such as the winding wire diameter of 0.1mm) can obtain to gain preferably than the situation that winding wire diameter little (such as the winding wire diameter of 0.06mm) has big resistance value, just as in the present invention antenna 32 is placed on the situation in the metal package parts, but aspect gain characteristics, does not have what difference.

Therefore, in the present invention, can expect that the structure of antenna 32 has thin winding wire, therefore can form the antenna 32 of reduced size.

Therefore, according to another embodiment of antenna of the present invention, can expect that the winding wire diameter is 0.1mm or littler, preferably the 0.06mm diameter.

Though above-mentioned antenna 32 comes down to a kind of like this antenna of form, wherein center on the regulation number of turn (circle) of straight usually antenna core part winding around lead, but antenna 32 is not limited to this structure, and can be applied on any type of antenna, especially can be applied on the disclosed structure of submitting to by the inventor of Japanese patent application 2002-297095.

In addition, in the present invention, structural relation between antenna 32 and the metal package parts 31 and position relation all are important factors.

Correspondingly, be described in detail in preferred construction relation and mutual alignment relation between antenna 32 and the metal package parts 31 below.

Specifically, according to electronic installation 30 of the present invention, can be contemplated that, in the middle of the metal package parts 41 and the relation between the antenna 32 in being housed inside enclosure space, set up the main element thickness (as the thickness of main element 45 or the thickness of back cover part 41) of metal package parts and from the antenna to the main element 45 or the distance of back cover part 41 according to receiving sensitivity.

If set up described main element thickness or back cover part 41 thickness and from the antenna to the main element 45 or the distance of back cover part 41 according to receiving sensitivity, owing to might reduce the disturbance that resonance phenomena is caused by metal material near antenna, thereby, even for the metal package parts, also can improve receiving sensitivity.By such practice, even for radio controlled time meter, also may use titanium or stainless steel etc. to make main element, back cover part and preceding frame etc., therefore, just might be in mechanism and improve the function of radio controlled time meter in appearance, but do not reduce receiving sensitivity.

In addition, by means of the material of main element 45 or back cover part 41, the shape of back cover part, the position relation between antenna 32 and main element 45 or back cover part 41, and, might realize further improving described receiving sensitivity by increasing nonmagnetic substance etc.For the thickness of main element or back cover part with from the antenna to the main element or the distance of back cover part, determine the most effective numerical value by experiment confirm repeatedly.

Below with reference to the structure of document specific descriptions at the antenna 32 of the used metal package parts 31 of the present invention.

At first, in order to study the relation between receiving sensitivity and the watchcase, just like such shown in Figure 15 (A) and Figure 15 (B), distance D 1 between the inner surface of the main element thickness T 1 of main element 45, antenna 32 and main element 45, the back cover part thickness T 2 of back cover part 41, the distance D 2 of 41 inner surface all chooses as parameter from antenna 32 to back cover part, be determined by experiment the relation between these 4 parameters and the gain, gain is the peak height by the signal of antenna 32 receptions.

Used main element 45, antenna 32, back cover part 41 are all made for these experiments in each experiment that will illustrate below, their shape be suitable for electronic installation 30 (comprising the time meter) in use.

Main element 45 and back cover part 41 are to select from following material: stainless steel, titanium, titanium alloy, gold, billon, silver, silver alloy, copper, copper alloy, brass, aluminium, aluminium alloy, zinc, kirsite, manganese, manganese alloy, superhard alloy (a kind of alloy that comprises tungsten carbide and titanium carbide); And, in all experiments, though the upper and lower difference that has several decibels, but, because in following all experiments, aspect the relation of any parameter (curve shape), all there is not substantial variation in gain, so use line-up of delegates used under the situation of stainless steel as the main consuming body parts 45 and back cover part 41 (because of preferred austenitic stainless steel, as SUS304, SUS304L, SUS316, SUS316L etc.).

According to first experiment, make it change in 5000 microns the gain of the signal that measurement receives from 0 in change main element thickness T 1.In this experiment, use an experiment antenna, this aerial coil has 1500 circles, conductor diameter is 65 microns, antenna is placed in the main element 45, and the distance setting between main element 45 and the antenna 32 is 1000 microns of steady state values, and back cover part 41 used thickness are 800 microns.Distance setting between antenna 32 and the back cover part 41 is 100 microns of steady state values, and the signal from transmission antennas transmit 40 KHz of installing in the position of regulation begins to experimentize thus.

Above-mentioned result of experiment has as shown in figure 16, when main element thickness T 1 since 0 micron (this condition promptly is not have main element 45) when increasing, the gain of received signal reduces gradually from-50 decibels, and when main element thickness T 1 reached 5000 microns, this reducing reached capacity.Solid line as shown in figure 16 is the curve of approximation of determining from experimental data.

According to first experiment, have been found that when main element thickness T 1 during the reducing of gain reaches capacity, and becomes constant above 5000 microns, numerical value at this moment promptly is minimum value.For this reason, if main element thickness T 1 is set at the 0-5000 micron, just may improve gain with respect to above-mentioned minimum value.In above-mentioned scope, if be considered as the actual available intensity of watchcase, the preferred practice is main element thickness T 1 to be set at 300 microns-5000 microns scope, and this is maximum actual numerical value.Consider the shell of electronic installation 30, i.e. the outward appearance of metal package parts, machinability and corrosion resistance etc., in order to form only main element, the preferred practice is main element thickness T 1 to be set at 500 microns-2000 microns scope.

According to second experiment, when making it between 0 and 40000 micron, the distance D 1 between change antenna 32 and the main element 45 measures the gain of the signal that receives.Figure 17 represents from 0 to 20000 micron above-mentioned experimental result.In this experiment, use an experiment antenna, aerial coil has 1500 circles, and conductor diameter is 65 microns, and antenna is placed in the main element 45, main element 45 used thickness are 2000 microns, back cover part 41 used thickness are 800 microns, and 41 distance setting is 100 microns of constant values from antenna 32 to back cover part, and, signal from transmission antennas transmit 40 KHz of installing in the position of regulation begins to experimentize thus.

Above-mentioned result of experiment has as shown in figure 17, and when distance D 1 increased, the gain of received signal was from increasing gradually in-54.5 decibels of beginnings of 0 micron distance D 1 (this condition is the situation that part antenna 32 contacts with main element 45).In this experiment, because the gain of the received signal of (removing the situation of main element 45) when only using back cover part 41 is-50.34 decibels, when gain increased to this value gradually, the gain at distance D 1 place between antenna 32 and main element 45 increase reached capacity.Making the distance D 1 that reaches capacity of gain in this way is 40000 microns, and antenna 32 main element 45 further away from each other can not cause the increase that gains.Solid line shown in Figure 17 is a curve of approximation of determining from experimental data.

According to second experiment, though have been found that gain is also increasing when the distance D between antenna 32 and the main element 45 1 increases, and receiving sensitivity also becomes and becomes better and better, but when distance D 1 surpassed 40000 microns, the increase of gain reached capacity, and gain becomes constant.

For this reason, if distance D 1 is located at scope 0-40000 micron, just may improve gain.In above-mentioned scope, if consider the actual situations of using such as size in the watchcase, the preferred practice is that distance D 1 is located in the 500-10000 micrometer range.

According to the 3rd experiment, when change bonnet thickness T 2 makes it between the 0-5000 micron, the gain of measuring received signal.Figure 18 represents the result of above-mentioned experiment at the 0-3000 micron.In this experiment, use experiment antenna 32, aerial coil has 1500 circles, conductor diameter is 65 microns, will be from antenna 32 to back cover part 41 distance setting be 1000 microns of steady state values, the thickness of used main element 45 is 2000 microns, will be from antenna 32 to main element 45 distance setting be 1000 microns, signal from transmission antennas transmit 40 KHz that are installed in assigned position begins to experimentize thus.

Be appreciated that from above-mentioned result of experiment shown in Figure 180, (this condition is not for there being back cover part 41 from 0 micron when the thickness T 2 of back cover part 41, at this moment gain is about-43.4 decibels) when changing to 800 microns, the gain of received signal sharply reduces, also be appreciated that simultaneously, when the thickness T 2 of back cover part 41 when 800 microns change to 5000 microns, gain not have such big variation.In other words, have been found that generation minimum value when the thickness T 2 of back cover part 41 is 800 microns.Solid line as shown in figure 18 is a curve of approximation of determining from experimental data.

In actual use, above-mentioned minimum value can not show any problem, and, in above-mentioned scope, consider the actual strength of the metal package parts 31 of electronic installation 30, preferably, back cover part thickness T 2 is set at scope from 100 microns to 5000 microns of numerical value, can produces maximum in this scope.Consider outward appearance, machinability and the corrosion resistance etc. of metal package parts 31, in order to form only bonnet, preferably, back cover part thickness T 2 is set in from 300 to 2000 microns the scope.

According to the 4th experiment, when the distance D 2 between change antenna 32 and the back cover part 41 makes it between 0 and 5000 micron, measure the gain of received signal.In this experiment, use experiment antenna 32, aerial coil has 2000 circles, conductor diameter is 65 microns, main element 45 used thickness are 2000 microns, and back cover part 41 used thickness are 800 microns, and 45 distance setting is 1000 microns of steady state values from antenna 32 to main element, signal from transmission antennas transmit 40 KHz that are installed in assigned position begins to experimentize thus.

Above-mentioned result of experiment as shown in figure 19 is that when distance D 2 increased, the gain of received signal increased gradually since 0 micron (this is the situation that part antenna 32 contacts with back cover part 41), and the gain under this condition is-49.6 decibels.In this experiment, gain is-38.8 decibels because (promptly remove the situation of back cover part 41) under a situation of the main consuming body parts 45, when gain was increased to this value gradually, the increase of the distance D 2 places gain that forms between antenna 32 and back cover part 41 can reach capacity.

The distance D 2 that gain is increased and reach capacity is 5000 microns, and antenna 32 also can not cause the increase that gains away from back cover part 41.Solid line as shown in figure 19 is a curve of approximation of being determined by experimental data.

According to the 4th experiment, though gain is also increasing when 41 distance D 2 increases from antenna 32 to back cover part, thereby cause excellent reception sensitivity, when distance D 2 during above 5000 microns, the increase of gain reaches capacity.For this reason, if distance D 2 is arranged on scope 0-5000 micron, just can improve gain.In above-mentioned scope, if consider the actual situations of using such as size in watchcase, the preferred practice is that distance D 2 is arranged in the 100-700 micrometer range.

Subsequent, with reference to Fig. 2 and describe a special case of electronic installation 30 of the present invention according to above-mentioned experimental result.

Fig. 2 is the profile of expression radio controlled time meter of the present invention, its basic structure described above.

The space 51 of regulation is provided between movement 42 and bonnet 41, and antenna 32 is arranged in this space.Antenna 32 is fixed to the lower surface of movement 42.

In the present invention, antenna 32 can be designed to contact,, also antenna 32 can be located in the space between the inner surface of antenna 32 and metal package parts 31 as the alternative mode of another kind with the inner surface of metal package parts 31.

In this special case, the two all uses austenitic stainless steel (as SUS316) for main element 45 and back cover part 41.According to above-mentioned experimental result, the thickness setting of main element 45 is 1600 microns, and the distance setting between the inner surface of antenna 32 and main element 45 is 2000 microns.The back cover part Thickness Design of back cover part 41 becomes 800 microns, and the distance setting of 41 inner surface is 3000 microns from antenna 32 to back cover part.

In the electronic installation 30 that constitutes as mentioned above, according to the radio signal that antenna 32 receives, the CPU in movement 42 makes the display driving part operation, so that drive, thereby can proofread and correct indicator 36 always.When doing like this, though main element 45 and back cover part 41 are made of metal in this special case, but, thereby reduced near the interference of antenna to resonance phenomena because each set point in the middle of the distance between main element thickness, back cover part thickness, antenna 32 and main element 45 and the back cover part 41 all is the value that obtains according to the experimental result that can obtain optimum reception sensitivity.

And then, if on the inner surface of back cover part 41 or on the inner surface of the main element 45 of metal package parts 31 nonmagnetic substance is being set, as gold, billon, silver, silver alloy, copper, copper alloy, brass, aluminium, aluminium alloy, zinc, kirsite, manganese, manganese alloy, and their resistivity is 7.0 micro-ohm cm, then might improve gain and be about the 2-3 decibel.

In addition, also can perhaps carry out cure process on the two on one of main element 45 and back cover part 41, as Carburization Treatment, gain does not have any reducing, and this can be illustrated by the performance of Carburization Treatment.

In the present invention another special case different with above-mentioned special case, though basic structure as shown in Figure 2 is identical, but the distance between the main element thickness of the material of main element 45 and back cover part 41, main element 45, antenna 32 and the main element 45, the thickness of back cover part 41, and the distance between antenna 32 and the back cover part 41 all is configured to different with above-mentioned special case.

Specifically, in this special case, main element 45 and back cover part 41 are formed by titanium.

For the situation that main element 45 and back cover part 41 all are made of titanium, if adopt the standard that adapts to the high pressure waterproof, then be 2000 microns thickness with the main element thickness setting, and, according to identical mode, be 1000 microns with the thickness setting of bonnet.

Owing to relation is arranged with the material of main element 45 and back cover part 41, even then the distance between antenna 32 and main element 45 and the back cover part 41 is very little, owing to can also obtain unchallenged receiving sensitivity, so can be 500 microns with the distance setting between antenna 32 and the main element 45, it be 400 microns with the distance setting between antenna 32 and the back cover part 41.

Be special case hereto equally, if at the inner surface of back cover part 41 or in the rear surface of main element 45 a kind of nonmagnetic substance is set, then the situation with above-mentioned special case is similar, might improve the about 2-3 decibel of gain.

In this special case, also can on one of main element 45 and back cover part 41, perhaps on the two, carry out cure process, as nitrogen treatment, gain does not have any reducing, and this can be illustrated by the performance of this cure process.

Another special case of meter had and the essentially identical structure of structure as shown in Figure 2 when the present invention shown in Figure 22 was radio controlled, but used different materials for main element 45 and back cover part 41.

Specifically, in the structure of Fig. 2, main element 45 and back cover part 41 are made by brass, then they are carried out the mirror polishing, after this, as shown in figure 22, electroplate by wet method, on them, form the coating 221,222 of Pd or analog, thereby make their polishings.Brass is a kind of nonmagnetic substance, its resistivity value is 7.0 micro-ohm cm or lower, confirmed this numerical value by experiment, thereby can produce excellent reception sensitivity condition that the set point one of this set point and main element thickness is used from improves receiving sensitivity.

Except electroplating, the main element 45 of this special case is identical with above-mentioned special case with back cover part 41, and the main element thickness setting is 1600 microns, and the back cover part thickness setting is 800 microns.Distance setting between antenna 32 and the main element 45 is 2000 microns, and 41 distance setting is 3000 microns from antenna 32 to back cover part.

By wet method electro-plating method is as described below arranged, form the coating 221,222 of main element 45 and back cover part 41.

At first, in order to form the lower floor of plating, (form: Na at electroplating bath ₂SnO ₃.3H ₂O 60g/l (grams per liter), CuCN 20g/l, K ₂SO ₃H 10g/l, KCN (arbitrarily) 30g/l, KOH 60g/l, Zn (CN) ₂Electroplate for main element 300 and 301 in 5g/l), the temperature of plating is that 50 ℃, current density are 2.4A/dm ², pH value is 12.5, settling rate is 0.33 micron/minute, lasts 6 minutes.By such work, on the surface of main element 300 and 301, form the following coating that thickness is about 2 microns Cu-Sn-Zn alloy.

Then, under the following conditions, forming the Sn-Cu-Pd alloy on the coating down.Electroplating bath: (form: Na ₂SnO ₃3H ₂O 60g/l (being equivalent to the amount of the Sn of 26.7g/l), CuCN 20g/l (being equivalent to the amount of the Cu of 14.2g/l), K ₂SO ₃H 10g/l, KCN (arbitrarily) 30g/l, KOH 60g/l, K ₂Pd (CN) ₄3H2O 30g/l (being equivalent to the amount of the Pd of 9.3g/l)).The condition of electroplating: the temperature of groove is that 50 ℃-55 ℃, current density are 2.0A/dm ², current efficiency is 47.8%, pH value is 12.5, settling rate is that 0.33 micron/minute, time are 9 minutes.By such plating, on following coating, form thickness and be about 3 microns Sn-Cu-Pd alloy, its hardness (Hv) is about 300, and density is 9.6g/cm ³After using scanning electron microscopy and X ray micro-analysis device that this composition of this coating is simply quantized, can confirm that this composition is a kind of three element alloy, by weight, this composition is by 17.12% Sn, 44.22% Cu, and 38.66% Pd forms.

After above-mentioned steps, use following condition on the Sn-Cu-Pd alloy layer, to electroplate again, form the coating of polishing.Coating bath: the Parabright SSS (ProductName) of Co., Ltd (Japanese pure chemistry reagent).The plating condition: temperature is that 55 ℃, current density are 1.5A/dm ², pH value is 7.6, settling rate is that 0.33 micron/minute, time are 6 minutes.By such plating, form thickness and be about the Pd coating of 2 microns white gloss, thereby finish coating 221,222.

To be formed with the main element 45 and the back cover part 41 of above-mentioned coating 221,222 on it, submergence was carried out anticorrosive test after 24 hours in a kind of synthetic solder paste, did not have the exposing surface color, had good corrosion resistance.Wherein, the composition of described solder paste comprises sodium chloride 9.9g/l, sodium sulphate 0.8g/l, urea 7.1g/l, ammonium hydroxide 0.19g/l, sucrose 0.2g/l and lactic acid (50%) 0.8g/l.Even main element 45 and back cover part 41 stand 200 ℃ heating in 5 hours test, coating 221 and 222 does not have any peeling off extremely yet, so have good heat resistance.

Still in this special case, though main element 45 and back cover part 41 are formed by metal, because main element thickness, bonnet thickness, in the middle of the distance between antenna 32 and main element 45 and the back cover part 41 each all are based on the experimental result that can realize optimum reception sensitivity, thereby near the interference minimum of the resonance phenomena antenna, receiving sensitivity is improved.In addition, because carried out surface treatment for main element 45 and back cover part 41, required corrosion resistance and the heat resistance of meter when radio controlled is provided, and because the white gloss with weight sense and high texture is provided, so the result is exactly high-quality outward appearance.

In all above-mentioned special cases, such shown in the back cover part 41 of Figure 22, if make the inner surface of back cover part 41 very smooth, there is not jut, and the shape of two secondary flats being provided for back cover part 41, then can reduce interference near the resonance phenomena the antenna 32, and, compare with the situation that wherein has jut, can improve about 2 decibels of receiving sensitivity.

In order to realize more compact thin time meter, can consider the direction of antenna 32 in addition again, and to make the distance between antenna 32 and main element 45 or the back cover part 41 be 0.

In addition, when the outer surface of antenna 32 being arranged to make antenna 32 is parallel to the inner surface of the inner surface of main element 45 or main element 45, perhaps during basically erectly perpendicular to the inner surface of back cover part 41, can consider the directivity of antenna 32 at an end face antenna 32 being arranged to make antenna.

Though the metal package parts 31 in above-mentioned special case are formed by main element 45 and back cover part 41, also can provide a preceding frame or an annulus at the top of main element 45.In addition, if any one in main body, preceding frame and the back cover part formed by nonmetallic materials, just may further improve receiving sensitivity.Separate with main element 45 by frame before making or analog, might improve receiving sensitivity.

If be not that all parts are all formed by nonmagnetic substance in main element, preceding frame and the back cover part,, also can improve receiving sensitivity even the part in the middle of them is formed by nonmagnetic substance.

In these cases, the effective and preferred practice is, makes one of antenna 32 with the outstanding part of planar fashion or have only the end of antenna 32 to make with nonmagnetic substance.

The situation that may occur is, not only uses one type metal and nonmagnetic substance, also can use the combination of polytype metal and nonmagnetic substance.

Similar with above-described experiment, in the middle of selection is used for the material of main element 45 and back cover part 41, the antenna that reality is used is placed in main element 45 and the back cover part 41, with the actual formation of the material that will use, and experimentize, in experiment, go out signal from the transmission antennas transmit that is installed in assigned position.

This result of experiment shows: for gold, billon, silver, silver alloy, copper, copper alloy, brass, aluminium, aluminium alloy, zinc, kirsite, manganese, manganese alloy, superhard alloy (a kind of alloy that comprises tungsten carbide and titanium carbide), with compare for the gain of stainless steel, titanium, titanium alloy, ramet situation, gain has improved the 2-3 decibel.Similarly experiment shows, not only for the good metal external component of receiving sensitivity, and,, just can improve the externally receiving sensitivity of the antenna of components interior by providing receiving sensitivity good a part of metal for the metal external component of receiving sensitivity difference.

Relatively the resistance value of the metal that uses in experiment can find that the value of resistivity is the receiving sensitivity that 7 micro-ohm cm or littler resistivity can be kept.The result, have been found that, if use nonmagnetic substance, gold, billon, silver, silver alloy, copper, copper alloy, brass, aluminium, aluminium alloy, zinc, kirsite, manganese, manganese alloy, superhard alloy are whole or a part of as the metal package parts, even utilize the metal package parts, the also receiving sensitivity that may realize.

In addition, verified, even,, just can realize certain receiving sensitivity if its part is the parts of being made by above-mentioned nonmagnetic substance for the metal package parts of the electronic installation that constitutes by the metal with high resistivity (for example stainless steel, titanium, titanium alloy, ramet).

In addition, material for main element 45 and back cover part 41, though also there is such situation: painted in order to realize the subregion, want former frame or zone similarity to adopt resin component, decorate perhaps for the situation of this structure, even with resin and to be installed on the sidewall of main element, as ornament, but obviously, in basic structure, use the situation of metal to drop in the scope of metal package parts of the present invention.

In the present invention, can also expect that described structure is: the inner surface of metal package parts is parallel with the outer surface of antenna basically, and perhaps the outer surface of the inner surface of the bonnet of metal package parts and antenna is parallel basically.

In addition, the preferred practice of the present invention is that the structure of the back cover part of metal package parts has the secondary flat shape.

The preferred practice also has among the present invention, makes an end face of antenna ends be substantially perpendicular to the inner surface of the back cover part 41 of metal package parts 31.

In the present invention, can expect with at least one resistivity to be that the non-magnetic part of 7.0 micro-ohm cm is fixed on the inner surface of metal package parts 31, can also expect that further nonmagnetic substance is at least a in the middle of gold, silver, copper, brass, aluminium, zinc, manganese or their alloy.

In addition, the preferred practice is among the present invention, constitute described antenna 32 by magnetic core 38 and the coil of forming by a plurality of wire turns 40 on magnetic core 38, and make parts by nonmagnetic substance, make antenna 32 at least along a planar projection on these parts, described plane comprises the axle that magnetic core 38 or this parts project into parts on it.

Preferably, in the present invention, constitute described antenna 32 by magnetic core 38 and the coil of forming by a plurality of wire turns 40 on magnetic core 38, and, antenna 32 or with described antenna corresponding components or with an end of the corresponding part of described parts, make by nonmagnetic substance.

Except above-mentioned each special case, also must provide anlistatig measure, and in the present invention, the preferred practice also has, and makes at least a portion of metal package parts 31 be provided with conductive component.

As Electrostatic Treatment of the present invention mechanism, for example utilize on the part that is expected at main element 45 or back cover part 41 a suitable conductive component is set, and there is predetermined distance the position that is provided with of conductive component apart from antenna 32, it is also contemplated that further conductive method is such as being welding, silver-colored paste, conducting ring or electroconductive resin or crimping etc.

For example, establish in figure or the radio controlled time meter at a kind of electronics, under the situation that pushes or pull out a part of button or minor axis, this structure should be such, between suitable contact point, exist and be in contact with one another, thereby can make static discharge, perhaps this structure should be able to be inserted a suitable conducting ring electronic installation or when radio controlled in the meter.

In addition, when radio controlled, in the meter, can weld at least one position on main element or the preceding members of frame, perhaps also silver-colored paste can be added at least one position between main element and the preceding members of frame.

Subsequent, can realize another kind of structure for electronic installation 30 of the present invention, purpose is to make the resistance value of at least a portion of attachment 39 to be different from the resistance value of another position, and used for this purpose method is: the plane surface area of at least a portion that makes the attachment 39 that at least two metal partss by jointing metal surface part 31 form is less than the plane surface area of the remainder of attachment.

The method that achieves this end can also be, that part of material thickness that the coil 40 of the antenna 32 of main element 45 and/or back cover part 41 is projected on is more a little than the thin thickness of the material of another part of main element 45 and back cover part 41.

In realizing the actual research process that uses of the present invention, the inventor has studied, in electronic installation 30, the activating pressure of attachment 39 will cause the variation of the gain of antenna 32, and described attachment 39 are formed between a plurality of metal partss that constitute the metal package parts 31 with a plurality of metal partss.

Specifically, the inventor has studied and has been made of two or more metal partss under the situation of metal package parts 31, at the assigned position of peripheral part normally, by one or more methods in fact such metal parts is bonded together, for example, utilize predetermined pressure, they are in contact with one another and are welded on one; Use a plurality of bolts to make them in place, they are assembled together mutually, promptly at first form protruding and recessed screw thread separately, and then they are screwed in together, and use predetermined fastening force to fix them threadably by crimping method with predetermined fastening force.Perhaps adopt internal thread method, filler fixing means, tenon interlock fixing means, connection method, welding method, method for welding, trough of belt are counter fast bores method of attachment and solid-state diffusion joint method etc. they combine.

The inventor has studied in metal package parts 31, and the variation of the contact pressure of the composition surface of a plurality of metal partss will change the gain of antenna 32.

In other words, in electronic installation in main element 45 and the back cover part 41 interconnective metal package parts 31, if when the Tightening moment of back cover part 41 changes, there is variation in the gain of antenna 32 (decibel), as shown in figure 23.

Specifically, once studied if make Tightening moment change to 6Nm from 0, then Tightening moment becomes strong more, and reducing of antenna gain is many more, and it is 3 decibels that maximum gain reduces.

In addition, when Tightening moment surpasses 6Nm, though owing to there is not actual available measuring equipment not measure, but as seeing from Figure 23, in metal package parts 31, when making contact pressure between main element 45 and the back cover part 41 become stronger, antenna gain descends.

Therefore, can predict, in metal package parts 31, except the use screw method makes main element 45 and back cover part 41 joints, use above-mentioned welding method, the fixing means that uses a plurality of bolts, flange crimping, the filler chucking method of describing in the past, tenon interlock clamp method, quick connection method, welding, method for brazing, the anti-connection method of boring of trough of belt, and one or more methods in the middle of the solid-state diffusion joint method etc., can realize just like above-mentioned identical effect.

For this reason, the inventor has finished following experiment, and purpose is to study the reason that above-mentioned phenomenon takes place.

At first, shown in Figure 33 (A) and 33 (B), the characteristic value of the antenna 32 under more following two kinds of situations, a kind of situation are to use a Vdd contact spring R in electronic installation 30, another kind of situation is by removing or crooked Vdd contact spring R, interrupts and the contacting of back cover part 41.

Result of experiment shown in Figure 24.

In Figure 24, carry out DATA REASONING for the data before changing, measuring condition is normally to use Vdd contact spring R, also carries out DATA REASONING for the data after changing, measuring condition is the contact of interrupting between Vdd contact spring R and the back cover part.

If compare these two kinds of data, the characteristic value of observing antenna 32 simultaneously comprising gain data, as can be seen, does not have substantial difference between these two kinds of data.

Yet,, also can eliminate the influence of the Vdd contact spring R that causes by fastening force even come fastening back cover part 41 by removing Vdd contact spring R.

Then, as Figure 34 (A) with (B), the inventor is the characteristic value of antenna 32 relatively, relatively is at the contact point that removes between movement 42 and the back cover part 41, and eliminates and carry out under the situation that fastening force that movement 42 is fastened to back cover part 41 causes the deformation influence.

What represent among Figure 25 is just like such shown in Figure 34 (A), by the contact point between bolster P maintenance movement 42 and the back cover part 41, with this contact point the data before changing to be carried out DATA REASONING.And such shown in Figure 34 (B), carry out DATA REASONING for the data after changing, at this moment removed the contact point between movement 42 and the back cover part 41.

If compare these two kinds of data, the characteristic value of observing antenna 32 simultaneously comprising gain data, just as can be seen, there is no substantial difference between the two.

Yet, even, also can eliminate the influence that causes by fastening force to movement 42 by removing the fastening back cover part 41 of bolster P.

In addition, such shown in Figure 26 (A), the inventor has inserted a suitable insulator between the main element 45 of metal package parts 31 and back cover part 41, the inventor has studied the influence that movement 42 is produced when reducing when back cover part 41 compresses caused range of pressure values.

Its result is illustrated among Figure 26 (B).

In Figure 26 (B), under the condition of not inserting insulator, carry out DATA REASONING, and under the condition of inserting insulator, carry out DATA REASONING for the data after changing for the data before changing.

If relatively these two kinds of data even because also see gain when the fastening force on the movement 42 reduces any increase is not arranged, can make movement 42 be out of shape and reduce the gain of antenna 32 so be difficult to the fastening force of imagination back cover part 41.

In this case, the inventor has carried out research repeatedly for the experimental result of Fig. 6 and Fig. 8.

The experiment of Fig. 6 and Fig. 8 is to utilize the screw threads for fastening moment of 3Nm to finish.

If there are the part attachment to stay in as shown in Figure 8 the fan section, then have as described above, be appreciated that the fact that the gain of antenna 32 slightly reduces.

The inventor has also finished the another one experiment.

Specifically, in the structure of Fig. 6, use metal package parts 31, the structure of metal package parts 31 should make the fan section that gap 55 is provided be configured to have 90 ° central angle, and when changing the fastening force of back cover part 41, measure the gain of antenna 32.

The results are shown among Figure 27.

In Figure 27,90 ° curve is the curve that is illustrated in gained antenna gain in this experiment, and " current curves " is illustrated in the curve of the gain of the antenna that uses in the metal package parts 31 that do not form gap 55.

From these experimental results as can be seen, compare with the structure in past, Shi Yan structure hereto, the decay quantity of the antenna gain that is caused by the Tightening moment of back cover part 41 has very big reducing.

It is contemplated that from these results, because can improve antenna gain by the threaded portion around the cutting antenna, so, Tightening moment by making back cover part is very high, just can utilize antenna threaded portion on every side to assign to produce magnetic coupling, produce the eddy current that resonance phenomena takes place in the sort of obstruction antenna thus, thereby make reducing of antenna gain.

Therefore, in the present invention, the main element 45 of metal package parts 31 and the engaging force between the back cover part 41 are provided with too much to be not to be preferred, therefore, according to specific joint method, to need a correct Tightening moment or engaging force because can think.

Yet even the Tightening moment of all samples that uses in this experiment all is invariable, but behind waterproof test, this unsettled moment also can change.

For example, be set at the situation of 2Nm for Tightening moment, behind waterproof test, the maximum moment of loosening is 1.6Nm, and it is 0.8Nm that minimum is loosened moment, and on average loosening moment is 1.1Nm (measuring 30 samples).For setting Tightening moment is the situation of 3Nm, and behind waterproof test, it is 3.5Nm that maximum is loosened moment, and minimum and stabilizing moment is 1.7Nm, and on average loosening moment is 2.5Nm (measuring 30 samples).

Tightening moment can make the waterproof test failure less than the sample of 0.1Nm, and is irrelevant with the value of Tightening moment.

From the above as can be seen, because the Tightening moment of measuring greater than 6Nm is difficult, and, therefore can think that loosening moment is 6Nm or littler, is acceptable because Tightening moment there is no need for antenna gain greater than 6Nm.

From the above as can be seen, loosening moment can be 0.1-6Nm, in practice 0.2-3.5Nm preferably.

And then, for methods such as filler chucking method and tenon interlock clamp methods, be 10 even take the active force (calling mutual peeling force in the following text) of main element and back cover part apart ^-4Nm, for waterproof test also without any problem.

Yet, because the mutual peeling force of measuring greater than 6Nm also is very difficult, and because also need be greater than the mutual peeling force of 6N.m, so peeling force can be 10 mutually for antenna gain ^-4Nm-6Nm.

Therefore, the electronic installation of another embodiment of the present invention has: at least one antenna, be used for handling the messaging device of the information of capturing by described antenna, and the metal package parts, antenna and messaging device can be contained in wherein.Wherein, the structure of described metal package parts can make described antenna can receive magnetic flux, and described magnetic flux is from metal package parts outside, and by these metal package parts, and resonance can take place.And described metal package parts comprise main body (sidewall) parts and a back cover part, and wherein, main body (sidewall) parts and back cover part are bonded with each other, and the mutual peeling force scope between main body (sidewall) parts and back cover part is: 10 ^-4Nm is to 6.0Nm.
