Embodiment Construction

[0055] exist figure 1 A schematic side view of the screwed connection of the module terminal 63 to the cable lug 21 is shown as prior art in . The cable lug 21 establishes an electrically conductive connection to a load system 51 (not shown) of a motor vehicle 50 (not shown). The module terminal 63 establishes an electrically conductive connection to the storage module 60 for electrical energy. The threaded fastener 20 or the screw connection should be implemented vertically for accessibility to the screwing robot in the production line. This results in the necessary bending of the module end 63 and a correspondingly high material requirement for the solution shown. The screw connection clamps the cable lug 21 to the module terminal 63 with a predetermined torque and thus creates an electrically conductive connection. Furthermore, screwed connections should be checked for correct torque over time as screwed connections loosen due to vibration and material movement.

Abstract

The invention relates to a connection coupling (1) for an electrically conductive connection of a storage module (61) for electrical energy in a motor vehicle (50) to an electrical consumer system (51) of the motor vehicle (50) for providing electrical energy, with a first connection coupling half ( 2) and with a second connection coupling half (4), the first connection coupling half (2) being a plug (2a) and the second connection coupling half (4) being a socket (4a) for receiving the plug (2a), wherein the plug (2a) and the socket (4a) is designed to establish an electrically conductive connection to one another, and the socket (4a) has a plurality of movable contact elements (8) on its inner lateral surface (6) for the frictional contacting of the plug (2a). The invention further relates to a storage system (60) with a connection coupling (1) and at least one storage module (61) for electrical energy, and to a motor vehicle (50) with a storage system (60).

Description

technical field [0001] The invention relates to a coupling coupling for electrically conductive connection of storage modules for electrical energy in a motor vehicle. Furthermore, the invention relates to a storage system with a storage module for electrical energy comprising a plurality of storage cells (Speicherzellen, sometimes called storage cells), as well as to a storage system with a storage module for electrical energy and an electrical load system (elektrischen Verbrauchersystem, sometimes called electrical consumer system). Background technique [0002] A number of implementation possibilities are known for the electrical contacting of the storage module to the load system of the motor vehicle. The load system of the motor vehicle is usually connected to the storage module by means of a screw connection and thus provides conductivity. The screw connection can be screwed with a predetermined torque and thus reproducibly produces a similarly maintained electrical ...
