Device for transferring current between two contact points which are movable relative to each other

Claim 1

In a device for transferring current between two contact points, there being a ribbon cable connected between the two contact points, said ribbon cable serving as an electric connection and being wound in turns concentric to each other in the manner of a spring housing, the cable having at least one electrical conductor having its ends firmly attached to the two contact points, and wherein at least one of the two contact points is movable relative to the other along a path concentric to the turns of the ribbon cable, there being ends of the ribbon cable which are folded to protrude at an angle of 90° from the ribbon cable, and wherein the device includes insulators, each of the ends of the ribbon cable which contain a fold of the cable being embedded in one of the insulators, the insulators being produced by molding and having parts disposed on the ends of the ribbon cable around the axes of which insulators said ends are pivotable, the device further comprising prefabricated, approximately L-shaped moldings of a mechanically stable insulating material, the moldings having flat walls and a U-shaped cross section slid over the folded ends of the ribbon cable, each molding being at least partially surrounded by one of the insulators.
