And after the integral sintering, the tail end of the glass insulator is filled with sealant in a sealing mode and provided with a rubber pad, the panel is provided with an O-shaped ring, the O-shaped ring is fixed through a locking nut, and the butt joint cavity is provided with an interface sealing gasket and a sealing ring. The utility model discloses preparation simple process, bearing capacity, sealing performance are good, can realize the reliable connection of inside and outside circuit of pressure vessel.
Description
One, technical field
The utility model belongs to technical field of electric connectors.
Two, background technology
The common at home at present use of hermetic seal connector, the overwhelming majority is used in the vacuum seal occasion, and the sealing property examination mainly is to carry out under the atm difference condition.Along with the expansion of application scenario, increase day by day as the circuit connection requirement under the environmental conditions such as high-pressure bottle, high-tension apparatus, deep water, the hermetically sealed connector that satisfies under the high pressure occasion also arises at the historic moment.Because under the high pressure occasion, part is subjected to very big quiet (moving) attitude pressure in the connector chamber, so structural strength and the sealing property key that become high pressure sealing of connector under the high pressure occasion.For satisfying above-mentioned requirements, now adopt the single hole sintering at present usually, to improve the anti-pressure ability of glass insulator itself, the defective of this method is:
1, can not adapt to the high-density connector occasion.Because the high-density connector pitch of holes is little, contact is arranged closely, and housing must be arranged processing sintering chamber by the position, hole, and difficulty of processing is big, and positional precision is difficult for guaranteeing;
2, by behind position, the hole requirement processing sintering chamber, wall thickness reduces greatly between housing bore, is unfavorable for the application scenario under the high pressure more;
3, behind the single hole sintering, the connector insulation property reduce greatly, have reduced dependability.
Three, summary of the invention
The purpose of this utility model is a problem such as solve the above-mentioned processing difficulties of high-density sealed connector, reliability is low, insulation resistance is low, provide a kind of high accuracy, highly reliable, be easy to the whole hermetically-sealed electrical connector of one-way high-pressure that technology realizes.
Purpose of the present utility model is achieved in that this electric connector comprises shell, contact, glass insulator, described glass insulator is sticked to form by two gobs with holes, contact passes two gob holes and places in the lump in the housing, and is integral sintered fixing.
Integral sintered back glass insulator tail end embedding fluid sealant also is equipped with rubber blanket, and panel is provided with O type circle, and this O type circle is fixed by locking nut, and the butt joint chamber is provided with interfacial seal pad and sealing ring.
For improving connector entire compression ability, shell is provided with step surface, forms two gob diameter differences of glass insulator accordingly, and integral body is the T type behind the applying sintering.
After adopting said structure, the utlity model has following advantage:
1, shell inner cavity only need be processed into simple shape, need not process the sintering chamber and can pass through the once sintered moulding of sintering mold on housing, has simplified manufacture craft;
2, after the glass sintering moulding, the afterbody pressure overwhelming majority transfers on the shell step, has improved Vitrea compressive property greatly;
3, after integral sintered, insulation, sealing property are good, and insulation resistance can reach more than the 5000M Ω, and leak rate is less than 1 * 10

4, this structure is applicable to all contacts arrangements, not limited by the contact spacing.
Four, description of drawings
Fig. 1 is the whole hermetically-sealed electrical connector structural representation of the utility model one-way high-pressure;
Among the figure: 1-shell, 2-interfacial seal pad, 3-sealing ring, 4-locking nut, 5-O type circle, 6-shell step surface, 8-rubber blanket, 9-fluid sealant, 10-glass insulator, 11-contact, 12-bail.
Five, embodiment
Below in conjunction with accompanying drawing the integral sintered formula hermetically-sealed electrical connector of the utility model one-way high-pressure is described in further detail.
The whole hermetically-sealed electrical connector of the utility model one-way high-pressure (we are called socket) is divided into butt end and tail end, and the butt end can be passed the high-pressure bottle perforate and place atmospheric environment; Tail end is in the high-pressure bottle, places hyperbaric environment, and pressure direction points to the butt end by tail end.Use ordinary plug and seal socket pairing to plug together and to realize that the inside and outside circuit of pressure vessel is connected.
As shown in Figure 1, the whole hermetically-sealed electrical connector of the utility model one-way high-pressure comprises shell 1, contact 11, glass insulator 10, form the main body of this hermetically-sealed electrical connector, wherein according to arts demand, consider glass ware forming thickness coupling, glass insulator 10 is made into the different gobs with holes of two diameters in advance by the glass insulator faying face, contact 11 passes two gob holes and places in the lump in the housing 1, integral sintered fixing, gob is combined closely at the faying face place and is become one, and makes glass insulator and shell 1 simultaneously, thereby contact 11 sealed knots reach excellent sealing performance.After the sinter molding; at tail end embedding fluid sealant 9; the one, increase the leakage damping, improved sealing property; it two is that effectively cover glass insulator 10 is avoided foreign impacts; simultaneously rubber blanket 8 can be bonded to connector afterbody cavity; by printing hole position mark on rubber blanket 8 in advance, make the tail wiring pin by mark identifying hole position sequence number, make things convenient for the product bonding wire, use when signal is searched.This connector panel is provided with O type circle 5 simultaneously, and this O type circle is fixing by locking nut 4, and the butt joint chamber is provided with interfacial seal pad 2 and sealing ring 3, and the shell butt end is provided with bail 12.When the whole hermetically-sealed electrical connector of this one-way high-pressure is installed and used, by clamping locking nut 4, make O type circle 5 and installation interface tight compression, thereby connector is installed and fixed, prevent to install the gas leakage of tapping simultaneously.When seal socket is connected with ordinary plug when separating,, realize connecting fast and separating by the bail 12 of plug body butt end.
For improving the whole bearing capacity of connector, its shell 1 is provided with step 6, the corresponding two gob diameter differences of forming glass insulator 10, integral body is T type structure behind the applying sintering, its advantage is in the tail end high-pressure chamber, gas pressure is delivered on the shell step surface 6 by rubber blanket 8, fluid sealant 9, glass insulator 10, strengthened the bearing capacity of hermetically sealed connector greatly, surpass the destruction that effectively prevents the pressure generation under the environment of 20atm at pressure, improved the reliability of connector high-pressure work.
