Abstract

Abstract A clock spring connector which has a shorter length of a flexible cable and can suppress noises. In a ring-shaped space between an outer cylindrical portion of a first housing and an inner cylindrical portion of a second housing, there are disposed a flexible cable wound in opposite directions with a reversely looped portion being at a U-turn point, and a carrier member rotatable following the reversely looped portion. A spacer as part of the carrier member slides over a rib provided on a bottom plate of the first housing.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 135 words
A clock spring connector comprising a stationary member, a movable member rotatably connected to said stationary member, a flexible cable stored in a space between an inner cylindrical portion provided on one of said stationary member and said movable member and an outer cylindrical portion provided on the other of said stationary member and said movable member, and a carrier member disposed in said space and having an opening, said flexible cable being reversely looped through said opening in opposite directions upon said inner cylindrical portion and said outer cylindrical portion, wherein a projection is provided between said carrier member and at least one of a top surface and a bottom surface of said space for making smaller a contact area between said carrier member and one of said top surface and said bottom surface.
Claim 2
Dependent Claim 135 words
A clock spring connector comprising a stationary member, a movable member rotatably connected to said stationary member, a flexible cable stored in a space between an inner cylindrical portion provided on one of said stationary member and said movable member and an outer cylindrical portion provided on the other of said stationary member and said movable member, and a carrier member disposed in said space and having an opening, said flexible cable being reversely looped through said opening in opposite directions upon said inner cylindrical portion and said outer cylindrical portion, wherein a projection is provided between said carrier member and at least one of a top surface and a bottom surface of said space for making smaller a contact area between said carrier member and one of said top surface and said bottom surface.
