Connection Device for Rotating Subassembly of a Motor Vehicle and Rotating Subassembly

A connection device for a rotating subassembly of a motor vehicle for electrically connecting a first electrical component of the subassembly, which is arranged in a hollow shaft of the subassembly, to a second electrical component of the subassembly, which is arranged outside the hollow shaft, the connection device comprising:

• a sleeve configured to be arranged in a radial leadthrough of a wall of the hollow shaft;
• a wire-like conductor arranged in regions in the sleeve, wherein conductor ends projecting at edges of the sleeve form contact regions configured to contact the first and second electrical components;
• and
• an electrically insulating covering that surrounds the conductor at least inside the sleeve, and which is arranged between an outer side of the conductor and an inner side of the sleeve,
• wherein, in order for the connection device to withstand with respect to operating loads resulting from rotation, the conductor has a first undercut configured to produce a radially positive-locking connection between the conductor and the covering, and the covering has a second undercut configured to produce a radially positive-locking connection between the covering and the sleeve.
