Description

The present invention relates to a device for Connect a line leading to a consumer with an electrical connection.

Electrical consumers, such as ceiling lamps, usually have a supply line with a the electrical connection provided for the ceiling becomes. This electrical connection has several vacancies wires on which different phases of the electrical current and the screwdriver binders or clamp connectors with appropriate wires be connected to the lamp lead. For assembly at for example, a ceiling lamp is either direct attached to the ceiling and then the supply line connected to the electrical connection, or the lamp is by means of one on the electrical supply line Holder attached to a hook on the ceiling hangs before the lead with the electrical connection is connected in the manner described. To connect the lead with the electrical connection are both when using a screw connector as well Using a clamp connector both hands required so that at this moment the fitter hands - free on the Top of the ladder stands and easily balance can lose, so that there is a high risk of accident lies. In addition, he must when connecting the individual wires pay attention to their correct assignment so that its conc tration on this and not on its safe stand the head is directed so that here the danger of Loss of balance and as a result of the risk of accidents  is further increased. There is also a risk here that the fitter when connecting the ceiling lamp with the exposed wires of the electrical connection in Touch comes in, which inadvertently does not work switched fuse lead to a short circuit can, and much more serious to another to a serious Injury to the fitter can lead to his death can. This danger does not only exist when connecting a ceiling lamp, but generally when exposed Wiring the electrical connection if, for example in new buildings when handling ladders or iron pipes the connection wires are touched. Furthermore, the Contacts of the exposed lines at renovation be accidentally painted over by what later rework also to a potential Ge driving source leads.

Likewise, the connecting wires can be replaced by a Accidentally torn down ceiling lamp exposed and that offer described risk, but the ceiling lamp can only be torn out of the holder and otherwise still connected to the electrical connection is, so that with a touch of the possibly zer an electric shock disturbed the ceiling lamp described consequences of injury is possible.

Against this background, it is therefore the task of the present ing invention, a device for connecting a a consumer leading line with an electrical Providing connection that is easy and quick is to be installed and a secure connection or enables secure attachment of the consumer. Farther should be a mix up when connecting the consumer the connecting wires are avoided, and when dismantled  Consumers are supposed to touch or damage exposed connecting wires must be excluded.

After all, the device should also be unqualified Allow people connected electrical consumption cher, such as B. ceiling lights to remove yourself and to reattach.

This object is achieved by a device according to the claims. The device according to the invention for connecting a line leading to a consumer comprises an electrical connection

• - one attachable to a wall or ceiling Base part,
• A holding device for holding the consumer,
• - A connectable to the electrical connection Socket and
• - one that can be arranged on the line, into the socket insertable connector,

wherein the base part has a recess for receiving the Hal has device that by means of a bolt on the Ba sisteil is fixable, which is inserted into the socket added connector is designed as a latch. Here the plug closes the feed opening to the recess at least partially, so that the consumer on the base part is fixed.

According to the invention, a device is thus available with which, in particular, Dec kenlampen can be assembled and disassembled without the user must have concerns about this operation. To the base part is first attached to the ceiling,  after the socket with the connecting wires of the electrical Supply line or connection was connected. Then the ceiling lamp is preferably with her Lead into the Haltvor arranged in the recess direction introduced so that it from the base part to the Blanket is held when the holding device for example as integral with the base part as a known deflection clamp is trained. Finally, the Lei end of the plug inserted into the socket, in a preferred embodiment the Feed opening to the recess for the holding device covers, so that the held by the holding device Consumers at the same time through the plug on the base part is fixed. Removal of the ceiling lamp lead from the holding device, and thus from the base part only possible after the plug has been removed. Plug and / or socket are preferably like this designed so that they all electrical lines, d. H. also the neutral conductor with a single plug-in process connect.

Although an integral design of the holding device with the base part certainly many advantages in particular in terms of the number of parts it offers an embodiment of the holding device as a separate component still more advantageous. In this way it is possible different lamp types by means of different Include fixtures in the same base part. Therefore, according to a preferred embodiment, the Holding device as a separate, on the line or on Consumers themselves trained component. Purpose moderately, the holding device is separate from the plug educated. In a preferred embodiment shows the holding device has no current-carrying elements a direct electrical contact to the lamp during to avoid hanging.  

This preferred training in particular Installation of a ceiling lamp further simplified as this first by the fitter on the floor on the holding device can be attached before the fitter on the ladder rises and the holding device in the recess of Inserts base part so that the ceiling lamp on the base part is held. He can do this with one hand that he has the other hand to maintain balance can always hold on to the ladder. That will be the accident risk significantly reduced.

The ceiling lamp can be attached to the holding device be screwed on, for example directly or by means of an intermediate pipe fitting. Likewise can the ceiling lamp also by means of its supply line in the Holding device are attached, which is advantageous for this is designed as a deflection clamp, for example as a plate-shaped element with two spaced apart Through holes.

After inserting the holding device into the corresponding The recess in the base part becomes the holding device and thus the ceiling lamp by inserting the plug in the socket is fixed to the base part. The fixation results through the cover of the feed opening Recess for the holding device through the connector. The term "feed opening" is used here both for Opening of the recess in the base part, which the Haltvor direction, includes, as well as that at integral with provided the base part trained holding device Openings for receiving the supply line in particular Ceiling lamp.

You can insert the plug into the socket also done with one hand, so that the risk of accidents  is further minimized, not least by the The fact that this simple connection process is quick is possible and therefore the fitter only has a short time on the Head spends. Since the socket expediently so is designed so that they are not exposed, touchable has electrical contacts, is only complete digem insertion of the plug into the socket an electrical conductive connection to the consumer established. Thereby it is excluded that the fitter when connecting the Lamp or the consumer accidentally with contacts or cables that are live. Thus, the fitter no longer has to switch to the switching state of the pay attention to the corresponding fuse or that the corresponding lines are voltage-free are.

Disassembly of the ceiling lamp by removing the Holding device from the base part is only after one Removal of the plug from the socket possible, which at the same time the electrical connection of the ceiling lamp is interrupted with the electrical connection. In order to However, for example, if the Lamp due to an accident first the electrical connection the ceiling lamp with the electrical connection underneath before breaking the ceiling lamp from the base part can solve. So there is also a possible one destroyed lamp no risk of injury Touching exposed lines. In addition, the base partly with a torn ceiling lamp or with a properly disassembled ceiling lamp Connection wires on, so that here too there is a risk of unintentional touch may be live standing lead wires is eliminated. But it has to Base part due to improper handling  to be replaced is an approximation with one of the electrical contacts still excluded.

Although the socket is integral with the base can be formed, it is advantageously as a sepa rates, insertable into a recess in the base part Component formed, the socket and the Recess are preferably designed so that the Socket only in a certain position in the recess is insertable. On the one hand, the assembly of the Device further simplified, since the easy to first Handling socket designed as a simple component attached to the connecting wires of the electrical connection is closed before it goes into the recess in the base part is inserted and then befe on the ceiling or the wall is increased. Secondly, by the given one position of the socket and thus also the position Position of their contacts in the base part defined, so that a safe and reliable connection without a Swapping of phases possible when inserting the plug is. This significantly increases the operational safety of the device according to the invention, as well as the advantageous Training, according to the socket on the wall or on the base part attached to the ceiling fixed in the recess is. This makes the socket safe and reliable in the Base part held, even if the plug for example for an intended replacement of the ceiling lamp pulled or due to an accident with major force is torn out. In any case, at a distance voltage of the connector from the base part the electrical connection interrupted and thus the risk of short circuits and potentially dangerous injuries avoided.

To increase operational safety also helps if according to a further advantageous embodiment of the  Device connector through a guide in the base part is guided, the guide being designed so that it only leads the plug in a certain position. So that will achieved that the connection of the plug with the plug can, which also has a defined position in the base part has, is only possible in a certain position. Also this contributes to an increase in operational safety, since then only the phases assigned to each other can be connected.

To avoid getting off the ceiling or wall protruding connecting wires of the electrical connection after connecting with that arranged in the base part Exposed socket is advantageously in the base part a chamber is provided for receiving the connecting line. This preferably has a cover, so that after connecting the socket to the connecting wires of the Connection line and attaching the base part to the Wall or the ceiling the exposed wires can be introduced into the chamber. By inserting the Cover, the chamber is then closed to the outside, so that the connecting wires are no longer damaged or can be touched unintentionally. Still can by a pre-cut recess on the cover an additional management in the chamber with the supply line was wired to another lamp leads. Even if the socket with the connector cable or the plug with the leading to the consumer Line can be connected in any way for example by soldering, it is nevertheless advantageous if this according to preferred embodiments by Ver screws or clamps are connected. With that the Assembly further simplified and possible faster and thus subsequently the risk of accidents is further minimized.  

With this described in detail above, The device of the invention is a safe, reliable casual and simple electrical and mechanical connection a line leading to a consumer an electrical connection possible. Especially at Ceiling lamps are their quick and easy replacement also possible by unqualified staff, which at for example for trade fairs, exhibitions and sales rooms, but is also beneficial for private households. To the The only thing that needs to be exchanged here is the plug, which Holding device fixed in the base part, from the socket be pulled so that the holding device with it arranged ceiling lamp taken from the base part can be. This is possible with one hand, as well connecting a new ceiling lamp so that the second Hand on the ladder during the whole process the risk of accidents can be significantly minimized becomes. Furthermore, before loosening the ceiling lamp electrical connection to the electrical connection forced frequently interrupted, so in this regard too especially with regard to unintentional degradation tearing the ceiling lamp security is significantly increased. It is also easy and quick to assemble menstecken of the individual components possible, these due to their respective training only in one agreed location can be put together, so that Swap parts or mix up connections is excluded. Finally, are also included Dismantled ceiling lamp may not be live free connection wires, so that the risk of short circuit or risk of injury from unintentional contact this lead is also eliminated.

The invention is based on a preferred Embodiment with reference to the accompanying Drawings explained in more detail. It shows:

In Fig. 1, a base part 1 with an inserted socket 3 is shown in a perspective view. The base part 1 has a substantially round base crack and is essentially can-shaped. In its center it has a fastening opening 5 , with which it can be fastened to a ceiling, for example by screwing. For receiving the socket 3 , the base part 1 has an upwardly open recess 7 , which in turn has an opening 9 directed to the side, so that the contact openings 11 of the socket 3 are accessible. Furthermore, the base part 1 has a chamber 13 for receiving the connecting lines or cables, not shown, which is open at the top in order to be able to accommodate the connecting cable protruding from the ceiling. To the side, the chamber 13 is closed by a removable cover 15 , so that the chamber 13 and thus the connecting cable located there is accessible even when the base part 1 is mounted on the ceiling. The chamber 13 is also connected via an opening 17 to the recess 7 , wherein when inserted into the recess 7 socket 3, the socket 3 is arranged with a connecting web 19 in the opening 17 . The connecting web 19 of the socket 3 has connections not shown here, into which the connecting wires, also not shown, are inserted to produce an electrical connection.

Furthermore, the base part 1 has a centrally arranged recess 21 which is open at the bottom and to the side and is designed to accommodate the holding device 23 . The lateral opening is designed as a feed opening 25 . For this purpose, the recess 21 has two laterally arranged guide grooves 27 which serve to guide and hold the holding device 23 described below and are open towards the feed opening 25 . In addition to the feed opening 25 of the recess 21 , a guide surface 29 with guide grooves 31 is arranged on one side and the opening 9 with the contact openings 11 of the socket 3 on the other side.

The guide surface 29 with the guide grooves 31 serves to receive and guide a plug 33 , which is shown in FIG. 2. The plug 33 has a plug body 35 which is connected via a line 37 to a ceiling lamp, not shown. At one end, the plug body 35 has contacts 39 , which are designed and arranged so that they can be inserted into the contact openings 11 of the socket 3 . To this end, a guide surface 41 is formed on the plug body 35 , which cooperates with the guide surface 29 formed on the base part. A guide web 43 is formed on the upper and lower edge of this guide surface 41 , which are in turn arranged and designed such that they interact with the guide grooves 31 on the base part 1 .

In Fig. 3, the holding device 23 is shown in a perspective view. The holding device 23 is essentially plate-shaped and has two holding beads 45 , which are each formed on opposite sides of the holding device 23 . Furthermore, it has a guide hole 47 and a guide hole 49 , which each pass through the plate-shaped holding device 23 . A side 51 of the holding device 23 arranged between the two holding beads 45 is adapted to the shape of the recess 21 in the base part 1 , so that it is semicircular when viewed from above in the exemplary embodiment shown here.

In Fig. 4, the socket 3 is finally shown in a per perspective view. The socket 3 is adapted in its outer shape to the recess 7 in the base part and has a connecting web 19 . The connecting web 19 in turn has connections 53 , into which the connecting wires of the electrical connecting line, not shown, are inserted. Furthermore, the socket 3 has contact openings 11 , into which the on contacts 39 of the plug 33 are inserted. The connection contacts are preferably asymmetrically ausgebil det, so that incorrect mating is not possible. The neutral conductor is expediently designed in a special shape or position in order to avoid a short circuit when plugging together. When inserted into the recess 7 socket 3 , the contact openings 11 are accessible through the opening 9 in the base part 1 and the connec tion bridge 19 is arranged in the opening 17 so that the connections 53 are accessible from the chamber 13 . Due to the special design of the socket 3 , which is adapted to the recess 7 in the base part 1 , it can only be inserted into the recess 7 in a predetermined position, and it also closes flush with the top of the base part 1 , as can be seen in particular in FIG. 1 .

The function of the illustrated embodiment will now be described in detail below. The holding device shown in FIG. 3 is used to attach a ceiling lamp (not shown) to the base part 1 . For this purpose, the holding device 23 is first attached to the line of the ceiling lamp, not shown, for example, the line is first carried out through the guide opening 47 upward and then flipped and is guided back down through the guide opening 49 . The deflected above the web formed between the guide holes 47 and 49 web 55 fixed line in this way, the device Haltvorrich 23 in the manner of a deflection clamp, so that the ceiling lamp arranged on the line can now be fastened by means of the holding device 23 in the base part 1 .

For this purpose, the holding device 23 , to which the ceiling lamp is fastened by means of its line in the manner described, is inserted with its side 51 adapted to the recess 21 in the base part 1 from the side or the feed opening 25 into the recess 21 . In this case, the holding beads 45 formed on the opposite sides of the holding device 23 are inserted into the guide grooves 31 of the recess 21 and guided and held by them. The holding device 23 is pushed so far into the recess 21 until it is completely received in it, ie until the end face 57 of the holding device 23 is flush with the guide surface 29 arranged laterally next to the recess 21 of the base part 1 .

The ceiling lamp is now held in the base part 1 by the holding device 23 and subsequently also securely and reliably fixed in the base part 1 in the next step by inserting the plug 33 . For this purpose, the plug 33 is placed with its guide surface 41 on the side formed on the base part 1 next to the recess 21 guide surface 29 and pushed in the direction of the socket 3 ver, the out at the tip of the plug 33 formed contacts 39 point in this direction . Here, the trained on the plug 33 Füh approximately webs 43 in the appropriately trained Füh approximately 31 , which forms the side of the guide surface 29 out. The guide grooves 31 lead on the one hand the plug 33 when moving in the direction of the socket 3 , on the other hand they hold it securely and firmly on the base part 1 when it has reached its end position. The end position has reached the plug 33 when it is fully opening with its connecting contacts 39 in the contact 11 of the socket 3 is inserted, thereby producing the electrical connection to the ceiling lamp.

In this end position, the plug 33 covers the lateral feed opening 25 of the recess 21 with its guide surface 41 . Since the holding device 23 is held downwards by its holding beads 45 in the guide grooves 27 of the recess 21 , it can no longer be removed from the recess. In the event of a lateral movement in the direction of the plug 33 , the holding device 23 would abut the guide surface 41 of the plug 33 with its end face 57 and would prevent further movement in this direction. Should the holding device 23 be forcibly moved further towards the plug 33 , it would push the plug 33 out of the guide grooves 31 and subsequently out of the contact openings 11 of the socket 3 , so that the electrical connection to the ceiling light would be broken before the holding device 23 could leave the recess 21 in the base part 1 .

This significantly reduces the risk of short circuit and injury in the case of a ceiling lamp torn down as a result of an accident, especially since no exposed and live contacts remain on the base part 1 . The contact openings 11 of the socket 3 are not accessible from the outside in this case as well as in a properly dismantled Dec ken lamp, since the socket 3 is held safely and reliably in the recess 7 in the base part 1 , from which the socket 3 only upwards can be removed. However, since the base part 1 is fastened to the ceiling by means of the fastening opening 5 , the socket 3 can in no case be pulled out or torn out of the recess 7 .

Overall, it will be a very safe and reliable Device for connecting it to a consumer leading line with an electrical connection to Provided, which is also easy and quick to is installed and has a high level of operational reliability. Furthermore, this device is a faster and easy change of consumer possible, because of the one-hand production and separation the connection minimizes the dangers that arise become.
