Description

The invention relates to a socket, in particular a trailer socket for the electrical connection of a motor vehicle trailer to a motor vehicle, with a socket housing and a recorded therefrom contact carrier insert for receiving provided with electrical leads electrical plug contacts, wherein the socket housing a lateral recess for the lateral Wegführung having the leads.

A socket of the aforementioned, that is generic type is from the EP 0 982 811 known. The socket described here has a contact carrier insert, which is supported either directly or indirectly via an optional support body on a provided in the assembled state backward of the socket housing mounting plate. For a lateral routing of the leads, both the contact carrier insert and the socket housing and the optionally existing support body mutually aligned lateral recesses. Through this, the leads for a lateral Wegführung can be passed.

Although the from the EP 0 982 811 prior art socket has proven in everyday practical use, there is room for improvement, especially with a view to a simplified handling during assembly or disassembly.

It is therefore the object of the invention, from the EP 0 982 811 previously known socket to further develop that as a simplified handling is given especially in the assembly or disassembly.

To solve this problem, a socket of the aforementioned type is proposed with the invention, which is characterized in that the socket housing integrally formed therewith locking lugs for a rear support of the socket housing received contact carrier insert.

Unlike the socket after the EP 0 982 811 has the socket according to the invention via a socket housing having locking lugs, namely those which are integrally formed with the socket housing. These locking lugs are used in the assembled state of the socket of a rear support of the recorded from the socket housing contact carrier insert. Thus, without the use of an additional component in the form of a support body, an indirect support of the contact carrier insert with respect to a mounting plate provided in the assembled state of the socket rearwardly provided. According to the socket according to the invention thus takes place an indirect support of the contact carrier insert with respect to a mounted in the rear of the socket mounting plate instead of, but on the socket housing itself, that is without the interposition of an additional component in the form of a support body. The measures provided for the support of the contact carrier insert locking lugs are integrally formed on the socket housing. An assembly or disassembly of the contact carrier insert and thus the entire socket is thus possible in a simple manner. In addition, the socket according to the invention proves to be due to the lack of a support body for an indirect support of the contact carrier insert against a mounting plate as economical, both in terms of their production and with respect to their assembly.

The contact carrier insert is preferably in a support by the latching lugs to form a volume space for the rear routing of the Connecting lines arranged at a distance to the rear edge of the socket housing. Thus, there is no flush termination between the contact carrier insert on the one hand and the rear edge of the socket housing on the other hand. The indirect support of the contact carrier insert against a mounted in the ready-assembled state of the socket back of the socket housing mounting plate is rather formed such that a volume space between the contact carrier insert on the one hand and the rear edge of the socket housing, that is provided in the mounted state rearward of the socket housing mounting plate is formed. This volume space is used for Kabelwegführung, that is, the routing of the electrical leads, with which the recorded from the contact carrier insert electrical contacts are electrically connected. In this case, the routing of the leads takes place in an advantageous manner the rear of the contact carrier insert, which allows a simplified handling and thus a simplified assembly and disassembly.

In the final assembled state, the leads are back led out of the contact carrier insert from this. They then bend in the direction of the lateral recess formed in the socket housing and are passed through for lateral guidance. The particular advantage of this embodiment is that the connection lines can be laid freely within the volume space formed between the contact carrier insert on the one hand and the mounting plate on the other hand. There is no forced operation of the leads, as in the case of the EP 0 982 811 known construction is provided, namely that the leads are not only pass through a lateral recess in the socket housing but also through a lateral recess in the contact carrier insert. Since a free installation of the leads in the above-described volume space is possible in the embodiment according to the invention, a simplified handling of the socket results in particular with regard to a final assembly of the same. On a special leadership of the leads, the fitter does not pay attention. In addition, there is the advantage that regardless of the installation conditions on site, a different than the intended Kabelwegführung can be realized. Since a free installation of the connection lines in the volume space is possible, the connection lines can also lead away differently than via the actually provided for this lateral recess become. In the known socket construction this flexibility is not given. In this respect too, the socket according to the invention proves to be advantageous.

According to a further feature of the invention it is provided that the socket housing screw openings provided providing round webs which carry the locking lugs. In the load case, an immediate power dissipation without unnecessary Kraftumleitungswege is achieved. Moreover, the design of the round bars is particularly robust, so that an unwanted tearing of the round bars and / or the detents arranged thereon is reliably prevented.

The contact carrier insert is integrally formed according to a further feature of the invention. This also facilitates the assembly or disassembly friendliness of the socket according to the invention. In fact, it is no longer necessary to carry out an assembly of a contact support insert made up of a plurality of individual structural components in the run-up to a socket installation.

According to a further feature of the invention, the contact carrier insert and the socket housing on a mutually corresponding coding. This ensures that the contact carrier insert can be used only in a certain relative position relative to the socket housing in this. In this case, the coding means used are preferably a nose formed on the inside of the socket housing, which engages in a groove formed on the contact carrier insert.

The socket housing carries according to a further feature of the invention, a stop. In the final assembled state, the contact carrier insert rests against this stop with an edge. In this case, the stop is preferably formed in the form of an inner circumferential edge which carries a sealing ring on the upper side. By means of this sealing ring the unwanted entry of moisture and dirt is avoided, especially when the plug is plugged. In this case, the sealing ring is preferably arranged against rotation within the socket housing, which can be achieved, for example, characterized in that the sealing ring has projections which engage in correspondingly formed recesses formed in the stop edge of the socket housing.

Overall, the peculiarity of the socket according to the invention results from the fact that an indirect support of the contact carrier insert is achieved with respect to a mounting plate without the additional interposition of a support body. In this case, an indirect support of the contact carrier insert is preferred because it is thereby possible to create a volume space within the socket housing, which serves a variable and flexible routing of leads. In a direct support of the contact carrier insert on a mounting plate, the design of such a volume space would not be possible. In this case, the volume space in particular opens up the possibility of providing in each case a rear routing of the connection lines from the contact carrier insert, no matter whether the connection lines now leave the socket housing via a lateral or a rearward recess. According to the invention, the contact carrier insert is supported on the socket housing itself, that is to say there are neither supporting bodies in the form of legs arranged rearwardly on the contact carrier insert for direct support nor in the form of components additionally to be connected to the socket housing for indirect support.

The in the FIGS. 1 to 4 shown outlet 1 has a socket housing 2. In this, a contact carrier insert 3 is used in the assembled state, which is integrally formed. The contact carrier insert 3 has a plurality of openings 12 for receiving electrical plug contacts. In the exemplary embodiment shown, these are 13 openings 12.

The contact carrier insert 3 is formed from a cylindrical base body 21, which provides the aforementioned openings 12. Furthermore, the contact carrier insert 3 has an edge 17, which is arranged in one piece on the base body 21 and is formed circumferentially. The above-described embodiment of the contact carrier insert 3 can in particular according to the sectional view Fig. 2 be removed.

The socket housing 2 represents a in the Fign. unspecified recording space for receiving the contact carrier insert 3 available. In the course of assembly of the contact carrier insert is introduced into this receiving space from below, that is, the contact carrier insert 3 with respect to the plane of the drawing after Fig. 2 introduced from below into the socket housing 2. In this case, the socket housing 2 and the contact carrier insert 3 are position-coded relative to one another, which is ensured by the nose 5 formed on the contact carrier insert on the one hand and the groove 6 provided by the contact carrier insert 3 on the other hand. Only when the nose engages 5 of the socket housing 2 in the designated groove 6 on the contact carrier insert 3, the contact carrier insert 3 in the manner described above from the lower edge 14 of the socket housing 2 forth in the socket housing 2 to achieve the in Fig. 2 be inserted position shown.

As the representation after Fig. 2 reveals the contact carrier insert 3 is in the final assembled state with its peripheral edge 17 on the stop 16 of the socket housing 2. In this case, the stop 16 of the socket housing 2 as the inside of the socket housing peripheral edge is formed, the upper side carries a sealing ring 4, as in particular the representation after Fig. 4 recognize. In this case, the sealing ring 4 has a rotation-proof arrangement on projections 19 which engage in corresponding recesses 20 of the stopper 16.

For securing the socket to a in Figs. not shown mounting plate are preferably screws. The socket housing 2 therefore has screw through openings 10, which are provided by round webs 9. On the inside of this round webs 9 locking lugs 7 are formed, each round web 9 carries a locking lug 7. This factual context may in particular include FIGS. 1 and 3 be removed.

By means of the latching lugs 7, a latching of the contact carrier insert 3 is achieved with respect to the socket housing 2, wherein a latching takes place when the contact carrier insert 3 rests with its peripheral edge 17 on the stop 16 of the socket housing 2, as in Fig. 2 shown. The locking lugs 7 each have latching hooks 11, as the detail view Fig. 4 recognize. In the final assembled state, these latching hooks 11 engage behind the edge 17 provided by the contact carrier insert 3 and abut against the end face 15 of the edge 17, in particular as shown in FIG Fig. 4 recognize. An unintentional pushing back of the contact carrier insert in the direction of the lower peripheral edge 14 of the socket housing 2 is not possible in the latched position of the contact carrier insert 3. The contact carrier insert 3 is rather secured in position relative to the socket housing 2, wherein both a displacement of the contact carrier insert relative to the socket housing with respect to the plane of the drawing Fig. 2 upwards and downwards is not possible. In addition, over the given by the nose 5 and the groove 6 encoding a rotation of the contact carrier insert against the socket housing 2 is reached.

In the assembled state, the socket housing 2 to a in Figs. not shown mounting plate, with which the socket housing 2 is releasably connected by means of screw through the through holes 10 guided screws. The contact carrier insert 3 is supported relative to this mounting plate, indirectly via the latching lugs 7. When a force application of the contact carrier insert 3 in the direction of the lower peripheral edge 14 of the socket housing 2, which Kraftbeaufschlagungsrichtung example, when plugging a plug, which is on the Contact carrier insert 3 initiated force on the locking lugs 7, the round webs 9, the socket housing 2 and finally to the in Figs. not shown mounting plate derived. In this respect, the contact carrier insert 3 is supported indirectly relative to the mounting plate, not shown, in the case of loading.

How in particular clearly the Fig. 2 can be seen, the contact carrier insert 3 is arranged at a distance from the rear edge 17 of the socket housing 2, which has the formation of a volume space 13 between the contact carrier insert 3 on the one hand and the rear edge 14 of the socket housing 2 result. This volume space 13 allows a rearward routing of leads from the contact carrier insert 3 addition.

For a lateral routing of leads from the socket housing 2 addition, the socket housing 2 has weakened zones 8, as the FIGS. 1 and 3 can be seen. To form a lateral recess 18, the weakened zones 8 can be broken out accordingly.
