Abstract
A method of manufacturing an annular base portion of an electrical slip ring assembly having a plurality of conductive rings formed in the outer circumferential surface thereof is described. The slip ring base is molded, and grooves are machined into the outer circumferential surface thereof. Conductive strips are cut into a series of lengths forming conductive rings to be placed about the outer circumference of the annular base member. The individual lengths of conductive material are anchored to the outer circumferential surface of the slip ring base and a rolling pressure is exerted on them about the circumference of the base to cause the rings to be press fit into the grooves previously formed on the base. When the complete circumference of the ring has been press fit into its respective groove, the other end of the conductive ring is then secured to the base. An appropriate fixture is provided for exerting the lateral and a rolling pressure on each conductive ring to properly press fit it into a groove on the annular base member.
