ABSTRACT:
A slip ring assembly having a slip ring holder made of a composite dielectric material reinforced by layers of fabric is molded in one case with the slip rings positioned in the mold and in a second case grooves are machined in the holder for receiving the slip rings. The holder has at least one annular flange for mounting the assembly on a rotating part such as a spinner bulkhead of an aircraft propeller assembly. Slip rings are adhered to the composite material of the holder as a result of molding or use of an adhesive where the grooves are machined in the holder. Metallic wire connections can be fastened to the slip rings by welding which also serve to hold the slip rings in the grooves of the holder. The wire connections may have pins for receiving mating receptacles. Openings in the ends of the metallic wire connections are suitable for crimping wire connectors to the de-icers or de-icer terminals.
