Steering wheel, segmented slip rings and method of disposing segmented slip rings.

摘要

A segmented slip ring (9, 18) is disposed on an insulated base (8, 17), and has a portion made substantially flush with a surface of the insulated base. A contact pin (12, 13) makes sliding contact with that portion. A method of disposing the segmented slip ring on the insulated base comprises: a mounting process in which a plurality of segmented slip rings are disposed at fixed intervals in a shape of a ring on the insulated base, and a leveling process in which at least a part of the segmented slip ring on the insulated base where the contact pin makes sliding contact is made flush with the surface of the insulated base by means of thermal pressing. A steering wheel comprising: an insulated base (8, 17) having a surface; a plurality of segmented slip rings (9, 18) having surfaces, disposed separately on the insulated base along a circular line such that they are mutually insulated; a plurality of contact pins (12, 13) that make sliding contact with the segmented slip rings along the circular line, and are set facing the surfaces of the segmented slip rings; and interposing pieces provided between the adjacent segmented slip rings such that the contact pins can move smoothly across the segmented slip rings.
