BRUSH ASSEMBLY OF ALTERNATOR FOR VEHICLE HAVING IMPROVED BRUSH AND WIRING TO PREVENT LEAD WIRE INTERFERENCE DURING BRUSH EXTRACTION AND RETRACTION

摘要

Disclosed is a brush assembly of an alternator for a vehicle including a brush holder including a hollow brush holder body, and wired brushes each received in the brush holder, and adapted to be urged against a slip ring fitted around a rotor shaft by a spring along an axis of the slip ring, thereby coming into elastic contact with the slip ring to obtain an electrical connection to an external electrical device, each of the wired brushes consisting of a brush, and a lead wire electrically connected to the brush. The brush holder body of the brush holder has brush channels each adapted to receive the brush of an associated one of the wired brushes, and wire channels each arranged at one side of an associated one of the brush channels while extending longitudinally in parallel to the associated brush channel and communicating with the associated brush channel. The brush of each wired brush is received at one end thereof in an associated one of the brush channels, and elastically supported by the spring associated with the wired brush while being electrically connected with the lead wire of the wired brush at the one end thereof.
