Description

 Electrical plug connection

The present invention relates to a plug connection, in particular for the electrical connection line between a towing vehicle and a trailer or implement. Such a connector comprises a plug and a socket with a plug-in opening into which the plug can be inserted. The socket comprises a socket housing with the insertion opening and at least one retaining element connected to the socket housing. The retaining element is movably mounted relative to the socket housing about a first pivot axis and secures the plug inserted into the insertion opening against slipping out of the insertion opening. Furthermore, a means is provided for deflecting the retention element about the first pivot axis when the force acting on the plug against the insertion direction is exceeded and about the first pivot axis, thereby releasing the plug.

Plug connections are known from the prior art, in which the socket is closed with plug unplugged by a lid which is rotatably mounted on the socket housing. In most cases, the lid is biased by a spring, so that it automatically closes the insertion of the socket as soon as the plug is pulled out of the socket. In most of the known from the prior art connectors of this type is on the cover of the socket formed a latching nose, the latched when plugged into the plug itself or a suitable projection formed on the plug or engages behind this, so that the plug against a Slipping out of the socket is secured. The spring bias of the lid ensures that the latch of the socket cover always remains in engagement with the plug. So the plug is always secured against slipping out of the socket. Such a connector is known for example from EP 0568030 A1. In this connector, sharp-edged structures are formed on the locking lug of the socket cover, which cooperate with sharp-edged structures on the connector side. So should be prevented in any case that the hinged lid of the socket opens, and thereby unintentionally releases the plug, so that the plug can slip out of the socket. The problem with such connectors is that a large tensile stress acting on the connector or on the cable connected to the connector can result in damage to the connector or cable. For example, the connector for the electrical connection between a towing vehicle and a trailer or implement can be used. However, the connector is not designed to mechanically couple towing vehicle and trailer together. For this purpose, a mechanical coupling is provided. It sometimes happens that the mechanical coupling between towing vehicle and trailer is released, without loosening the electrical connector. This carelessness can cause the towing vehicle is moved without the trailer, which usually leads to damage to the connector or tearing off the electrical connection line.

To counteract this problem, it has already been proposed in DE 1207983 A to attach to the socket cover a resilient strap which extends over the cable hanging down from the plug. If you pull on the cable, so the cable stretches and starts by deflecting the bracket from its rest position. From a certain tensile stress, the deflection of the bracket causes the socket cover opens. The locking lug formed on the socket cover releases the plug so that it can be pulled out of the socket.

It becomes problematic if the tensile load acting on the plug or the cable does not act in the plug longitudinal direction. This is the case, for example, when the towing vehicle is not driven straight forward, but at a certain angle to the trailer longitudinal axis. In this case, the cable does not stretch in the longitudinal direction of the plug but obliquely to the plug length direction. In the plug connection from DE 1207983 A, this problem is counteracted by the fact that the spring-loaded bracket fastened to the socket cover has a certain width, so that it is also deflected by an obliquely tensioned cable. This solution is, however, only conditionally suitable for obliquely to the plug longitudinal axis tensioned cable. In addition, the resulting cable has proved unfavorable. Especially at very oblique angles of extraction, the cable is heavily loaded at the point where it enters the plug at the rear end of the plug. At this point creates a strong kink in the cable at very oblique Auszugswinkeln. The present invention has therefore set itself the task of developing the connector of the type mentioned in such a way that the plug is optimally secured against slipping out of the socket up to a certain tensile load even at an angle stretched cable, with damage to the outlet, plug and esp - Special cable should be effectively prevented.

The object is achieved by the technical features of independent claim 1. Accordingly, a solution according to the invention is the task before when the plug comprises a plug-in opening in the first plug part with a first plug axis and a cooperating with the retaining element second plug part with a second plug axis in that the plug is flexible at least between the first plug part and the second plug part, so that the second plug part can be deflected into an oblique position relative to the first plug part from a straight position, in which the second plug axis coincides with the first plug axis the second connector axis enclosing an angle with the first connector axis, the retainer being rotatable about a second pivot axis, and wherein the first pivot axis and the second pivot axis are different from each other and enclose an angle with each other.

The flexibility of the plug ensures that the plug can bend, so to speak. The rear end of the plug from which the cable is led out, therefore, can be pivoted relative to the front part of the plug, which is plugged into the socket. The kink, which arises in the cable at the point where the cable enters the rear end of the plug, is therefore extremely low, even with a very obliquely tensioned cable. This avoids damage to the cable at this point. The retaining element, which secures the plug against slipping out of the socket, can be optimally tracked due to the two pivot axes provided according to the invention if the plug is deformed due to an obliquely tensioned cable. The retaining element is thus always ideally aligned to secure the rear connector part to a certain tensile stress. The retaining element pivots with the rear part of the plug if you like. Advantageous embodiments of the present invention are the subject of the dependent claims. Preferably, first pivot axis and second pivot axis do not intersect. The first pivot axis is preferably a little further away from the insertion opening than the second pivot axis when the plug is inserted. As a result, the rear end of the plug and the rear end of the connector engaging retaining member can move synchronously.

In a preferred embodiment of the present invention, the second pivot axis is perpendicular to a plane in which the first pivot axis lies. As a result, the retaining element releases the connector from a certain tensile stress, even with diagonally tensioned cable always safely. Further, it is advantageous if the second pivot axis coincides with an imaginary axis about which the second plug part can be deflected with the plug plugged in because of the flexibility of the plug relative to the first plug part from the straight position to the oblique position. The first pivot axis is preferably always in a plane which is orthogonal to the second connector axis. This also ensures that the retaining element always reliably releases the plug even with an obliquely tensioned cable. The second pivot axis can also coincide almost with the imaginary axis.

In a further, particularly preferred embodiment of the present invention, a cover of the socket comprises a first cover part and a second cover part, wherein the first cover part is rotatably mounted about a third pivot axis on the socket housing, the second cover part about the second pivot axis relative to the first Cover part is rotatable, and the retaining element is rotatably mounted about the first pivot axis on the second cover part. The lid, which closes the plug-in opening of the socket when the plug is unplugged, thus simultaneously forms the retaining device according to the invention for the plug. To be able to insert the plug into the insertion, the lid must of course be opened. Preferably, in this embodiment, the second pivot axis extends centrally through the two-part cover and stands perpendicular to the plane which is spanned by the cover itself. First cover part and second cover part are preferably disc-shaped and lie flat on each other. The first cover part forms the lower part of the lid, through which the insertion opening is closed when the plug is unplugged. The second cover part forms the upper part of the lid and serves only as a holder of the retaining element. In this embodiment, it is particularly advantageous if the first pivot axis and the third pivot axis are aligned parallel to each other in a straight position of the second connector part.

Furthermore, in this embodiment, a return spring assigned to the third pivot axis is preferably provided, by means of which the cover is prestressed about the third pivot axis, so that it closes the insertion opening when the plug is unplugged. The return spring also ensures that the retaining element is held securely on the plug.

In a further, particularly preferred embodiment of the present invention, two brackets are provided as retaining elements, which extend substantially parallel to each other and are each rotatable about the common first pivot axis at one of its ends, wherein the two brackets are arranged symmetrically with respect to the second connector axis , The two brackets, the rear end of the plug, from which the cable is led out, thereby embrace on both sides of the cable, and thereby secure the plug from slipping out of the insertion. The symmetrical arrangement of the two brackets allows a uniform load bearing and prevents the plug from tilting against the retaining straps. The two brackets can be rigidly connected to each other so that they open together as soon as a certain pulling force acting on the plug is achieved. Alternatively, the two brackets can be independently movable.

Particularly preferably, each bracket has at least one positive locking element, which engages with a corresponding form-fitting element of the plug as soon as the straps secure the inserted plug against slipping out of the insertion opening. This ensures a stable hold of the plug in the socket until reaching the predetermined maximum load. For example, in the bracket, a recess may be formed, which cooperates with a formed on the plug end bump or a corresponding projection on the plug end.

In a further preferred embodiment of the present invention, the means by which the retaining element is deflected when exceeding a certain counter to the insertion direction acting on the plug force from the plug against slipping-securing position about the first pivot axis and the plug thereby free, one of the first pivot axis associated spring. Preferably, the spring is designed as a spiral spring and aligned in the direction of the first pivot axis. The spring presses the two brackets or the retaining element against the second plug part, ie against the rear part of the plug to secure the plug against slipping out. The spring force of the spring is dimensioned so that the retaining element or the two inventively provided bracket open and thereby release the plug when the puller acting on the plug exceeds a certain value. This is the case when the cable is under high tension. This predetermined value is chosen so that the plug is released in any case, before the cable breaks or the connector is damaged.

In a further preferred embodiment of the present invention, a return spring associated with the second pivot axis is further provided, by which the retaining element is biased about the second pivot axis into a preferred position in which the retaining element is aligned such that it optimally secures the inserted plug. when the second plug part is in the straight position. Preferably, the first pivot axis is in the preferred position in a plane which extends perpendicular to the plug longitudinal axis. This embodiment ensures that the plug is straightened if possible under light load.

An embodiment of the present invention will be explained in more detail below with reference to drawings.

For the following statements applies that the same parts are designated by the same reference numerals. If reference signs are contained in a drawing, which are not explained in more detail in the associated description of the figures, reference is made to the preceding or following description of the figures.

In Figure 1, the plug 2 of a connector according to the invention is shown. It comprises a front first connector part 2.1 and a second rear connector part 2.2, wherein the two connector parts 2.1 and 2.2 are connected to each other via a flexible connector part 2.3. The plug 2 can be inserted with the front first connector part 2.1 in the socket shown in Figure 3. From the rear second connector part 2.2, the cable 7 is led out. At the rear plug part 2.2 further two projections 10 can be seen, the function will be explained below. In Figure 1, the plug is shown in an unloaded state. The longitudinal axis X of the first plug part 2.1 coincides in this state of the plug with the longitudinal axis Y of the second plug part 2.2. The flexible part 2.3 between the first connector part 2.1 and second connector part 2.3 allows the rear second connector part 2.2 can be pivoted relative to the first connector part 2.1, so that the two axes X and Y form an angle to each other, as shown in Figure 2 , Figure 3 shows the socket 3 of the connector according to the invention. It consists of a socket housing 5 and a pivotable about the axis C on the socket housing mounted cover 8. The socket housing 5 has an insertion opening 4, in which the plug shown in Figures 1 and 2 can be inserted. A spring, not shown, is provided in the joint between the socket housing 5 and the cover 8, which ensures that the cover closes when the plug is unplugged and closes the insertion opening 4. The cover 8 comprises two parts, namely a lower part 8.1, which is connected via the pivot axis C articulated to the socket housing 5, and an upper cover part 8.2, which in turn can be rotated relative to the lower cover part 8.1 about the pivot axis B. The pivot axis B is substantially perpendicular to a plane which is spanned by the lid 8. At the front end of the upper cover part 8.2, two retaining clips 6 are attached, through which the plug shown in Figures 1 and 2 in the inserted state on slipping out the socket is secured. The two brackets 6 are not rigidly connected to the upper cover part 8.2, but mounted on this rotatable about the pivot axis A. The spring 11 ensures that the two brackets 6 exert a force acting in the direction of the socket on the plug and, with the plug unplugged, fold upward into the plane of the cover 8.

The two brackets 6 each have a recess 9 which, when the plug is plugged in, comes into engagement with the two projections 10 shown in FIG. 1 at the rear end of the plug. This is shown in Figure 4, in which the connector 1 according to the invention is shown with plugged plug. Figure 5 shows the connector 1 of Figure 4 from below. It can be seen that the cable emerging at the end of the plug is biased at an angle. The plug 2 bends thereby, so that the axis Y of the second plug part 2.2 to the axis X of the first plug part 2.1 includes an angle, as shown in Figure 2 already. The pivot axis B shown in Figure 3 between the lower cover part 8.1 and the upper cover part 8.2 allows the upper cover part 8.2 rotates with the second plug part 2.2, so that the two brackets 6 in this oblique position of the plug optimally to the two projections 10 of the rear second connector part 2.2 abut. Figure 5 also shows that the two brackets 6 symmetrically to the second connector axis Y, and thus rest on both sides of the cable 7, the rear connector part 2.2. The spring force of the spring 1 1 is dimensioned so that the two brackets 6 spring open and release the plug 2 as soon as the force acting on the cable tensile force F exceeds a predetermined value.

Figure 6 shows the connector according to the invention for comparison with relaxed cable 7. The indicated in Figure 3 spring 12 ensures that the upper cover part 8.2 is pivoted together with the two retaining straps 6 in a straight position, in the sense of alignment of the upper cover part 8.2 coincides with a straight orientation of the plug.
