Description

Vehicle-mounted electric network plug connector Technical Field The invention relates to a plug-in connector for a vehicle electrical system, in particular for a motor vehicle electrical system, in particular in a passenger vehicle, a truck or other motor vehicle driven by a motor. The in-vehicle electrical system plug connector is particularly suitable for high-voltage in-vehicle electrical systems. Background In automotive applications, there are various types of high-voltage onboard electrical systems. On the one hand, this may be an on-board electrical system with a voltage higher than 12V, for example 24V or 48V. As a result of the increasing number of Shu Shiyong electrical appliances in the motor vehicle, the recognition is made that it is advantageous to have a 48V on-board electrical system. However, this requires a different plug connection compared to a conventional 12V on-board electrical system. On the other hand, in particular in motor-driven vehicles, the on-board electrical system for the drive train can also be understood as a high-voltage on-board electrical system. The drive train is typically operated at a voltage of several hundred volts, for example about 400V. In addition to high voltages, high current levels are also to be expected on these electrical systems, since significantly higher power is required to drive the motor vehicle than to operate the electrical consumer. In such an on-board electrical system, particularly high demands are also made on the plug-in connection. It is in the case of high-dynamic automotive applications that high demands are made on the mechanical stability of the plug connectors of the on-board electrical system. The electrical plug connector for a vehicle electrical system must permanently ensure a stable and fault-free connection. Because of the high current levels, contact resistances of such plug connectors are also highly required in order to keep the heat losses at the transition low. For this purpose, a large-area contact surface between the connection partners is required. Disclosure of Invention In order to ensure a durable, stable, electrical fault-free connection with low contact resistance and high resistance to dynamic loads, a vehicle electrical system plug connector is proposed. The on-board electrical system plug connector has a first housing part. A first connecting element is arranged in the first housing part. The housing member has a longitudinal extension along a longitudinal axis. The housing part is formed in particular by a side wall and a bottom and an open cover. When referring to sidewalls herein and hereinafter, reference is made to plural and singular numbers throughout. The cover may also be referred to as an end side. The housing is formed in particular in one piece from a wall, a base and an end face. The housing part has an opening at the end face according to the invention. The connecting element arranged in the housing part is arranged in the housing part in a manner movable along the longitudinal axis. The connecting element can be moved in translation along the longitudinal axis in the housing element. The plug connector also has a second housing part in addition to the first housing part. A second connecting piece is arranged inside the second housing part. The second housing part is also formed by a side wall, an open cover and a bottom as the first housing part. The cover may also be referred to as an end side. The housing is formed in particular in one piece from a wall, a base and an end face. The housing part has an opening at the end face according to the invention. The connecting element arranged in the housing part is preferably arranged in the housing part fixedly with respect to the longitudinal axis. For connection, one of the housing parts is inserted into the other housing part and the connection parts are in electrical contact with one another. For this purpose, the connection element is composed of an electrically conductive material and/or is coated. The connection element may in particular be composed of a copper material or an aluminum material. It is also conceivable to coat the connecting elements, in particular on the surfaces of the connecting elements which come into contact with one another in the connected state. In this case, metal coatings, in particular tin plating, are possible. In the connected state of the plug connector, the housing parts are inserted into one another such that the longitudinal axes of the housing parts extend preferably in line with one another. Furthermore, the second housing part is fixed relative to the first housing part at least in the longitudinal direction, and the second connecting part is in mechanical contact with the first connecting part. The contact surfaces of the connecting elements are in contact with one another. The contact surface is in particular on the one hand the outer circumferential surface of one connecting piece, which is in direct contact w
