Description

connector

The invention relates to a connector according to the preamble of claim 1. The state of the art is referred to EP 1 873 865 A. For example, in the field of emergency power supply such switching devices are used to connect power contacts with each other and to solve each other. In this case, a further device section with the corresponding power contacts is pushed onto a basic device section with first power contacts. In addition to the power contacts, it is known to connect further contacts to the device sections which already contact one another in a test position before the device section is moved to the switched-on position, in which the power contacts are also connected to one another. In this way, it is already possible to carry out tests, for example, to check the functions of the device sections to be connected before reaching the connected position.

Against this background, the object of the invention is to provide a plug connection which has a flexibly adaptable structure and with which, nevertheless, the above-described functionality of contacting in a test position and displacing the plug connection in this state relative to an abutment can be realized ,

The invention solves this problem by the subject matter of claim 1. A plug-in connection for connecting terminal contacts of a first connector to corresponding terminal contacts of a second connector having corresponding mating plug-in faces and be contacted in a first position, wherein on the second connector, a displaceable abutment collar is arranged, which after plugging the at least one releasable locking device for locking the abutment collar in a locked position on the second connector, wherein the Locking device is designed such that the locking device from the locked position alone by translational Relativverschieben the mated unit of the first connector and the second connector by overcoming a frictional force is solvable and wherein the first connector and the second connector have a modular structure.

In this way, the functionality described in the introduction can be implemented in a simple manner on the one hand. Due to the modular structure also results in a particularly simple way to adapt to a variety of applications.

It is expedient if the first and the second connector each have a module holding frame, in which at least one or more connection modules are held. The connection modules can be designed the same overall. However, it can also be provided that at least two of the connection modules each have a different structure, which means that they can be used for different functions.

It is particularly advantageous if at least one of the connection modules is in each case designed to receive a data and / or signal plug or a data and / or signal plug socket, in particular in USB or RJ45 format, since the plug connection thus also serves for connection Such data and / or signal connectors can be used.

In a further preferred application, the first connector is fixedly mounted in a receptacle of a cabinet, a rack or a switchgear and the abutment collar and the second connector together form a slot in the locked state or are arranged on such a, for insertion into the Recording of the control cabinet, the rack or the switchgear is designed. This makes it easy to use the plug connection or several of the plug connections (two, three or more) on a control cabinet, rack or switchgear.

The connector according to the invention is simple and therefore inexpensive to implement. The locking device is constructed such that first clearly recognizable a locking position is achieved. Either in this position or shortly thereafter, the test position for performing tests is reached. The connected position or the "connect position" can only be achieved by further insertion with a higher insertion force, whereby even very high forces can be easily absorbed by the connector.

Advantageous embodiments can be found in the dependent claims.

The invention will be described in more detail below with reference to an exemplary embodiment and with reference to the drawings, in which:

FIG. 1 shows a first connector 100, which has a plurality-in this case three-connected modules 101, which are held together in a module holding frame 110. The connection modules 101 have housings 102, which are held non-positively and / or positively in the module holding frame 1 10, for example fixed in a latching manner. The connection modules 101 each have a connection side for connecting conductors, solder connections or plugs and a plug-in side with first plug contacts and thus jointly form a first plug face 1 1 1, the plug face 1 1 1 of the first connector 1. FIG. 2 shows a further plug-in connector 200, which has a plurality-in this case three-terminal modules 201 arranged next to one another, which are held together in a module holding frame 210. The connection modules 201 have housings 202, which are held non-positively and / or positively in the module holding frame 210, for example fixed in a latching manner.

The connection modules 201 each have a connection side for connecting conductors, solder terminals or plugs and a plug side with second - corresponding to the first plug contacts plugged together - plug contacts and form so together a second mating face 21 1, the mating face 21 1 of the second connector. 1

In this case, the first and the second mating face 1 1 1, 21 1 are formed correspondingly, ie, matched to one another such that the two mating faces (housing geometries and electrical and / or optical and / or pneumatic plug contacts 1 1 1, 21 1) can be plugged together and again are separable from each other.

The connection modules 101, 201 of the first and the second connector 100, 200 may each be the same or different. According to Fig. 1 and 2, they are the same. This is not mandatory. The connection modules can also be constructed differently, as long as their mating faces are plugged together. Thus, the mating contacts pin and beech contacts. However, it is also conceivable that the housings 102, 202 of the connection modules 101, 201 are themselves designed for preferably latching insertion of electrical or light-conducting plugs, for example for inserting data and / or signal plugs. Examples of suitable formats for such data and / or signal connectors are USB or RJ45 connectors 103 in one or more of the connection modules and corresponding USB or RJ45 sockets in the corresponding connection module of the other connector. In that regard, reference is made to FIGS. 3a and 3b and to FIGS. 4a and b. Then, the corresponding mating faces of these data and / or signal connectors can also form parts of the overlapping mating faces 1 1 1, 21 1 of the first and second connector 100, 200. In addition, it is provided here that the entire plug connection of the first plug connector 100 and the second plug connector 200 is displaceable relative to an abutment collar 300. Here, this abutment collar 300 is a sleeve which surrounds the module holding frame 201 of the second connector 200 (see FIG. 2).

On the abutment collar 300 and on the second connector 100, 200 components are formed, which each form a locking device 400 in their interaction. 2, two locking devices 400 are provided.

These locking devices 400 are designed so that they initially do not hinder that the first and the second connector 100, 200, from a disconnected position or a non-contacted position (Fig. 5a, 6a) are plugged into a contact position, in which the two plug-in faces 1 1 1, 21 1 are put together and in the corresponding contacts or plugs / sockets of the plug-in faces 1 1, 21 1 contact each other (called test position, see Fig. 5b, 6b).

The locking devices 400 are then configured such that it is possible to move the entire mated connector from the two connectors 100, 200 from the test position in the contacted state relative to the abutment collar 300 (here a sleeve) (called end position, see Fig. 5c , 6c). According to Fig. 7 to 10, the first connector 100 is stationary, then the locked unit of second connector 200 and abutment collar 300 can be pushed onto the first connector 100 and then the abutment collar 300 relative to the mating connector of the connectors 100 and 200 on this displaceable ,

This is particularly useful if, in addition to data and signal contacts of the connector, for example on the abutment or slot other contacts - eg power contacts - are provided, which should contact each other only in the end position and not already in the test position. This is explained in more detail in EP 1 873 865, to which reference is made. In this move remains the Contact between the contacts (104, 204 in Fig. 8c, 9c and 10c) of the connectors 100, 200 consist.

In the switched-on (power) position, the first connector 100 and the second connector 200 are translationally movable relative to the abutment collar 300 in a direction X together. The abutment collar 300 may be connected to a device to be wired or part of a shelf 501 for insertion into a receptacle 502 of a cabinet 500, a rack or switchgear or the like, or attached (e.g., bolted or latched) to this shelf 502. This will be described below in more detail with reference to FIGS. 7 to 10.

Subsequently, the abutment collar 300 is shown as movable and the connector from the connectors 100 and 200 are shown as relative to the abutment collar 300 (here the sleeve) and thus to be connected to the device movable. According to FIG. 7 a, for example, the first connector 100 is fixed to a type of cabinet or box receptacle 500. The second connector 200 is in turn locked to the abutment collar 300 that is fixed here on a type of insert 501, which is similar to a drawer in a receiving space 502 of the cabinet 500 inserted. It is only essential that a Relativverschieblichkeit the elements 100, 200 and 300 (preferably in the manner described below) is given.

The second connector 200 is fixed to / in the abutment collar 300 (here, a sleeve) with a locking device 400 fixed but at least limited displaceable after release of this locking device 400 relative to the abutment collar 300 (Fig. 5, 6 and 7).

From the non-contacting position of FIG. 5a, the second connector 200 is preassembled on the abutment collar 300 (in this case the sleeve) and is locked thereto by the locking device 400 (FIGS. 5a, 6a).

In order to achieve the connection in the test position, the second connector 200 with the abutment collar 300 now becomes common to the first connector 100 pushed until the first and the second connector 100, 200 are brought into a contacting position (Fig. 5b, 6b). At this time, the second connector 200 moves together with the abutment collar 300 as a unit relative to the first connector 100.

Between two narrow sides 212a, 212b of the substantially rectangular in plan view module holding frame 210 of the second connector 200 and corresponding narrow sides of the abutment 300 each one of the locking devices 400 is arranged / formed. By way of example, one of the two will be described below, wherein the locking devices 400 are here designed to be identical, so that the following statements apply to both locking devices 400.

The respective locking device 400 here has two lever-like, pivotable locking elements 414a, 414b which are each pivotally mounted on one of their ends here on pins 415a, 415b on the narrow sides 212a, 212b of the module holding frame 210 of the second connector 200 (FIG 6a-c)).

The locking elements 414a, 414b have at their pivot bearings or pins 415a, 415b opposite ends in each case a V-shaped end portion 41 6a, 41 6b.

The V-shaped end sections 416a, 416b are designed (see FIG. 7) to engage in corresponding slots 417a, 417b of a groove-like guide track 418 of the abutment 300 (FIG. 6b), from which they can also be swung out, and then into the guideway (418) are movable.

In the locking position, in which the V-shaped end portions 41 6a, b engage in the slots 417a, b, the first connector 100 is located relative to the second connector 200 in the not yet contacted position (Fig. 5a, 6a). In this position, between the two in this position parallel aligned locking elements 414a, 414b, a head 428 of a locking slide 419 which engages between the two V-shaped end portions 41 6a, b, so that their Mobility and thus a movement of the module holding frame 210 and the second connector 200 relative to the abutment collar 300 is blocked (Fig. 6a).

In this position, now the unit of the abutment collar 300 and the second connector 200 can be pushed onto the first connector 100 (Fig. 6b).

It is then advantageous that a device is provided which makes it possible to displace the locking slide 419 from the locking position of FIGS. 5a, 6a. For this purpose, the locking slide 419 passes through a receptacle 420, which is formed or attached to the narrow sides 412a, 412b of the module holding frame 201 of the second connector 200. This receptacle 420 is designed such that the locking slide 419 relative to the receptacle 420 and partially in this is displaceable.

The locking slide 419 further has a receiving space 421 for a return spring 422, by which it is held in a defined position, unless an X-direction force is exerted on it. The exertion of a force in the X direction is realized here by means of an actuating slide 423, which is immovably formed on the module holding frame 1 10 of the first connector 100.

The operating slide 423 displaces the locking slide 419 during the further insertion of the unit consisting of the abutment collar 300 and the second connector 200. The latter has the end widened at the end 428, so that the head 428 moves in the X direction when the frictional forces between the locking elements 414a, 414b is pushed past, so that a tapering 429 of the locking slide 419 adjoining the head 428 shifts between the two locking elements 414a, 414b, whereby it is possible for the locking elements 414a, b to pivot inwardly. In this way, the lock is released and the abutment collar 300 can be moved in the direction -X relative to the connector from the two mated connectors 100, 200 (see Figure 5c, 6c) in the contacted or switched position in which then possibly Also, power contacts, which are not shown here, are interconnected.

The contacts 104, 204 (see FIGS. 8c, 9c, 10c) of the first and second connectors 100, 200 which are brought into contact with each other are primarily those which serve to transmit data or signals.

Here, the design and dimensioning is advantageously further such that the locking slide 419 is already inserted so far in the test position that its head 428 no longer engages precisely between the two V-shaped end sections 41 6a, b, so that these out of the slots 417a, b swing back. The locking position is thus quasi quit "before" the achievement of the test position in the manner of Fig. 5b, 6b again, which has the advantage that the mechanical components in the test position of forces are further relieved, if this for example for longer Time is retained.

Pulling in a reverse direction causes the head 428 to move the locking hooks back into the slots 417 so that the home position can be resumed.

FIGS. 7 to 10 illustrate that the first connector 100 may be stationary in one or more receptacles 501 of a control cabinet or box 500. The second connector 200 and the abutment collar 300 then preferably form alone or with a kind of frame to which they are attached, a drawer-like drawer 501 for insertion into the receptacle 502 of the control cabinet 500. There are one or more, in particular more than two or three, such trays 502 provided. The second connector 200 can be pushed with the slot on the first connector 100. Upon a further advancement of the insertion, the locking position of the locking device is released, as described above with reference to FIG. 6. The remaining slot can then be moved on the second connector 200. Reference numeral first connector 100th
