ABSTRACT:
A full rotational, substantially zero friction electrical conductor assembly conducts relatively high electrical currents between a pair of relatively rotatable members. Electrical conductor modules are axially stacked to provide multiple circuit capabilities wherein each module has a pair of electrical conductive rings affixed to the rotatable members defining an annular radial gap therebetween. A plurality of resilient filamentary conductor loops are disposed between these conductive rings, and the loops contact, roll on, and are captured by the conductive rings thereby providing electrical continuity between the relatively rotatable members. Loop separating spools are interspaced between and in rolling contact with the conductor loops to prevent the loops from touching one another and generating frictional losses. A circular raceway, carried by one of the rotatable members, keeps the spools in rolling alignment with the loops.
