ABSTRACT:
In a clock spring connector using cables for electrical connection between a stationary member and a movable member which is rotatably mounted in relation to the stationary member, spiral or concentrical cable stowage grooves on both the stationary and the movable side are provided in a space for cable stowage, the cables being wound along either one of these cable stowage grooves and the remaining portion of the cables being wound reversely along the other cable stowage grooves, thereby decreasing the required length of the cables to half the amount of a rotation of the movable member.
