Abstract
A full or partial rotational, substantially zero friction electrical conductor assembly conducts the electrical currents of a large number of electrical circuits between a pair of relatively rotatable members in a minimum axial length. A plurality of concentric, annular, radially spaced gaps are formed between corresponding concentric, concave surfaced, electrically conductive rings affixed to the members, such that a large number of circuits may be accommodated in a reduced axial length assembly. Resilient, filamentary conductor loops are disposed between the conductive rings, and the loops contact, roll on, and are captured by the concave surfaces of the conductive rings, thereby providing electrical continuity between the relatively rotatable members. The conductor loops are sealed within individual structural enclosures, thus, providing an environmentally clean and rugged assembly.
