DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to an electrical plug-and-socket connection.


BACKGROUND OF THE INVENTION

In the known plug-and-socket connection of this type, the control means between the slide and the housing in which it is received consist in the slide being configured as a cradle, which is guided in a transversely displaceable manner in rails in the housing running transversely to the coupling axis. The coupling channel provided in the slide has an angled-off course and the axial height of this angular course determines the axial stroke by which, in the coupling situation, the two connecting parts are drawn one into the other under the transverse motion of the slide. In order to guide the housings of the two connecting parts deeply one into the other during the coupling operation and, at the same time, to bring into engagement the electrical contacts and mating contacts which are located there, the maximum possible axial stroke height is necessary. In order however to obtain a large axial stroke height, in the known plug-and-socket connection the clearance between the channel entrance and the channel end of the angled-off coupling channel in the slide had to be dimensioned correspondingly large. Both the slide and the housing in which it is received are thereby required to have a large structural height.
If, in the known plug-and-socket connection, a large axial stroke is desired, by movement of the slide, in the coupling and decoupling of the two connecting parts, then the climb from the angled-off coupling channel of the slide must not be too steep, since the slide otherwise becomes stiff to actuate. For a flat angular course of the coupling channel, a large transverse displacement distance of the slide in the housing is obtained however in return. The slide therefore, in its extended release setting, juts correspondingly far out of the housing. For the actuation of the slide, a correspondingly large lateral space is then required next to the connecting part in which the slide is received. Particularly in the use of plug-and-socket connections in the automotive field, this space is not always available, so that it has been necessary to make do with plug-and-socket connections having a small axial stroke.
In an electrical plug-and-socket connection of a different type (EP 0 501 502 A2), it is known to use for the coupling and decoupling operations, in place of a laterally extensible slide, a disk which is rotary-mounted on the housing of the one connecting part and which possesses two S-shaped channels which are diametrically opposed relative to their rotation journal. The one S-shaped channel serves as a coupling channel for the coupling journal of the other connecting part, while the second S-shaped channel interacts, as a control channel, with a control pin located on the housing of the first connecting part. As a result of the second control channel and the control pin, the rotary disk is moved with its rotation journal in an axial housing groove. The diameter of the rotary disk is determined by the sum of the axial height of the two diametric channels. A relatively large structural height of the rotary disk and of the housing in which it is rotary-mounted is therefore obtained. Furthermore, the rotary disk is made harder to manipulate, since it bears constantly with its inner face against the one outer side of the housing, while its outer face has a rib which is diametric to the rotary actuation of said rotary disk. The diametric rib can only be manually grasped in the journal region of the rotary disk, whereby only a relatively small rotation force may to be exerted. A small actuating force maybe to exert only correspondingly small coupling forces between the two connecting parts. Furthermore, the rotary disk cannot be brought into a laterally extended release setting in relation to the housing and nor, consequently, can it be retracted into the housing, like a slide, at high thrust.
In a further detachable plug-and-socket connection of different type (DE-41 29 236 A1), it is kn
