Abstract:
1. A rotation transformer for a cable connection comprising a longitudinal axis ( 1 ) and separation discs ( 3 ) having respective contact lugs ( 5 ) on an outer periphery wherein one end of a cable ( 4 ) is capable of executing a limited number of revolutions about the longitudinal axis ( 1 ) relative to its other end while maintaining an uninterrupted connection between the two ends, wherein each of the separation discs ( 3 ) is individually rotatable on the longitudinal axis ( 1 ) and the respective contact lugs ( 5 ) are structured to contact one or more adjacent lugs to limit a maximum angle of rotation between two adjacent discs ( 3 ) relative to one another, wherein a distance between two of the discs ( 3 ) allows a maximum of two turns of the cable ( 4 ) in one plane, and wherein the cable ( 4 ) is guided by a bearing arrangement on the transformer without crossing and wound between discs alternating from an outside diameter of a disc ( 3 ) to the longitudinal axis ( 1 ) and conversely from the longitudinal axis ( 1 ) to the outside diameter.
