Clock spring connector

摘要

Disclosed is a clock spring connector having: a fixed member; a movable member so mounted as to be rotatable relative to the fixed member; and a flexible cable for connecting the fixed member to the fixed member, the flexible cable being accommodated in between an inner cylindrical unit provided in any one of the fixed member and the movable member and an outer cylindrical unit provided in the other member and reversely wound on the inner and outer cylindrical units through a U-shaped turned-back portion. In this clock spring connector, a plurality of rollers connected by a wire spring to which an inward elastic biasing force is imparted are mounted outwardly of the flexible cable wound on the inner cylindrical unit. The flexible cable is press-biased towards the outer peripheral surface of the inner cylindrical unit by these rollers.
