Definitions

• the invention relates to the field of electrical connectors for establishing an electrical connection between two electrical areas separated by a wall.
• the invention relates to an electrical plug connector comprising a first plug connection part carrying electrical plug contacts, a second plug connection part containing electrical contact sockets and a guide sleeve designed for reaching through a mounting opening located in a wall, at one end of which the first plug connection part and at the other end of which the second connector part are arranged, which connector means are assigned for fixing it to the wall.
• the gear wall is the wall or partition between an electrical plate located inside the gear housing, on which a plug part with a pin housing carrying electrical plug contacts is arranged for its electrical contact.
• a socket part is provided, which can be plugged onto the electrical plug contacts with the contact sockets contained in the socket part in order to create the desired electrical plug connector.
• the socket part is arranged at one end of a line set, the other end of which is connected to the inputs and outputs of control electronics for monitoring and controlling the electronics contained in the transmission housing.
• Such a connector is known from utility model DE 297 21 908 U1.
• the plug part as described above, is part of the electrical plate from which the electrical plug contacts project from the gear wall.
• the plug contact arrangement is limited by a web-like receiving edge. Through this recording edge, a recording formed for receiving a guide sleeve.
• the guide sleeve is arranged so that it protrudes upward from the electrical plate through the gear wall and borders on the inside on the receiving edge.
• the guide sleeve is connected to the receiving edge by a bracket clip. With a section having locking grooves on the outside, the guide sleeve protrudes from the gear wall on the side opposite the electrical plate.
• the locking grooves serve to lock a bayonet ring assigned to the socket part to secure the electrical plug connection created.
• the bayonet ring has at its insertion end a support flange which is supported on the outer surface of the gear wall.
• the bayonet lock is designed so that when the bayonet ring is put on or when it is turned to bring about a lock, the guide sleeve is pulled out of the gearbox wall to a certain extent.
• On the gear wall notch-like elements facing the electrical plate are arranged, which engage in corresponding centering and fastening bushings assigned to the electrical plate.
• the bayonet ring is locked on the guide sleeve and the resulting pulling out of the guide sleeve or pulling the electrical plate towards the gear wall, the notch-like elements are pressed into the centering and fastening bushings assigned to them.
• the electrical connector and the electrical plate associated with the connector part are then fastened to the transmission wall.
• this known connector is that the guide sleeve must be fastened to the pin housing by means of a clip to mount the connector. Therefore, this known connector is not suitable for those applications in which it is not possible to reach behind the wall separating the two electrical areas in order to bring about electrical contacting. Sometimes the notch-like elements used for fastening to the partition are also not quite the ideal solution. In a so-called “blind assembly", in which electrical contacting between the two plug connection parts is to be brought about, the plug connection part located behind the wall - the pen housing - can only be reached through the mounting opening in the wall, it cannot be recognized whether the electrical panel has been properly attached to the inside of the wall.
• the reliability of the connector attachment to the wall depends to a large extent on the quality of the frictional connection between the outer surface of the notch-like elements and the cylindrical inner surfaces of the centering and fastening bushings. If a connection that is able to withstand high pull-out forces is to be established, this requires such a dimension configuration of the elements that look like a notched nail and the centering and fastening bushings, the former having to be pressed into the latter with great force. With the number of fastening points used - usually around three are provided - the force required to establish the connection also increases. Manufacturing tolerances in the arrangement of the centering and fastening bushings and the notch-like elements can result in the electrical plate being undesirably energized after the gearbox wall has been put in place.
• the object of the invention is to further develop an electrical connector of the type mentioned at the outset in such a way that not only safe “blind assembly” is possible with it, but also that it enables a stress-free attachment to the partition is.
• the one connector part and the guide sleeve cooperate with one another, by means of which a rotational assembly movement on the guide sleeve connects the two parts in an arrangement aligned with the longitudinal axis of the guide sleeve, and includes holding means, with which the connector is held on one side of the wall in the direction of the longitudinal axis of the guide sleeve with a stop to limit the amount of displacement of the connector directed away from the guide sleeve, and that the guide sleeve means for fixing are assigned to the guide sleeve on the wall side opposite the one connector part.
• the connecting means for fastening the guide sleeve to the one plug connector part located behind a partition are those with which a connection of these two parts can be brought about without additional elements.
• the connection between the guide sleeve and the connecting means is produced by exerting a rotational assembly movement on the guide sleeve, so that the connection between these two parts can be established by rotating the guide sleeve. If, for certain reasons, this rotary movement cannot be carried out or cannot be carried out completely, it can be felt by the fitter that proper fastening is not possible.
• a holder is provided so that the plug-in connection part arranged on the inaccessible wall side is aligned in a corresponding position with the mounting opening of the wall.
• the connector part is slidably supported in the direction of the longitudinal axis of the guide sleeve.
• An abutment arrangement limits the amount of displacement of the plug connection part directed away from the guide sleeve, so that the plug connection part is not pressed away when the guide sleeve is assembled.
• means are assigned to the guide sleeve which enable the guide sleeve to be fastened to the accessible wall side. The connector is thus fastened to the wall in an area of the connector which is accessible at all times, so that the connector can also be easily removed from the wall.
• the connecting means for connecting the guide sleeve reaching through the wall to the plug connection part located behind it can be designed, for example, in the manner of a thread or in the manner of a bayonet lock.
• a bayonet lock it is expedient to design the locking link as an annular body and to assign it to the plug connection part, whereas the guide sleeve is assigned radially protruding locking pins.

• the locks lungskulisse of the connector part can be formed starting from an insertion opening for inserting the locking pin in a plane perpendicular to the longitudinal axis of the guide sleeve or with an inclined portion which is directed transversely to the longitudinal axis and is inclined away from the insertion opening.
• the plug connection part is pulled towards the guide sleeve when the guide sleeve is fastened, so that the plug connection part can be brought from a mounting position in the holder into a plug connection position.
• a means for fixing the guide sleeve on the accessible wall side can be provided, for example, with a fastening tab formed radially on the guide sleeve and having an opening facing the wall, into which a screw for fixing the guide sleeve on the wall can be inserted or has already been inserted.
• a plurality of holding feet can be provided as holding means for the plug-in connection part, the width of which is held with play in a guide groove of a holder assigned to the plug-in connection part.
• the feet can, for example, be formed on a carrier plate of the plug-in connection part and be held in the guide groove by their material elasticity.
• An electrical connection between the inaccessible plug connection part, which can be, for example, the plug part provided with a pin housing, and the electrical / electronic components, which are arranged on a circuit carrier spaced from the plug connection part, is produced by flexible conductors, for example a foil conductor. Vibrations occurring between the unit carrying the electrical / electronic components and the partition are not transmitted from one unit to the other in this way.
