Electrical current transferring and brush pressure exerting spring device

摘要

A serpentine-shaped spring device having an internal core made of braided wires coated with elastomeric material for environmental protection and to enhance exertion of a low holding spring pressure on a metal fiber brush, when the spring device is suitably anchored at a stationary location to hold the brush in contact with a rotor during rotation thereof while conductively transferring electrical current thereto from the core of the spring device.
