Abstract
A cable assembly has a clamp provided at an end of a multi-core cable. The clamp, which is formed such that the inner diameter thereof increases as it is closer to the rear end, is fixed by caulking to the outer circumference of a sheath. An inner spring and an outer spring are arranged around the outer circumference of a sheath. The inner spring is fixed to the clamp in such a manner as the end thereof on the cable tip side is sandwiched between the sheath and the inner surface of the clamp. The outer spring is shorter than the inner spring in the cable axial direction, and the end thereof on the cable tip side is fixed to the outer circumference of the clamp. The outer circumference of the inner spring and the outer spring is covered with a rubber boot.
Claims4
A cable assembly comprising a multi-core cable, a cylindrical clamp, two layers of springs including an inner spring and an outer spring, and a rubber boot, wherein
- the multi-core cable includes a bundled plurality of core wires having each conductor covered with an insulation, a shielding layer provided around the plurality of core wires, and a sheath formed around the shielding layer;
- the cylindrical clamp is fixed by clamping the sheath at an end portion of the multi-core cable in a state where the multi-core cable is inserted in the clamp, whereas at a position opposite to a front end of the multi-core cable, the clamp has a diameter increasing portion such that the inside diameter increases as it is more distant from the front end;
- the inner spring having the multi-core cable partly inserted therein is attached around the sheath on the rear side of the clamp in a manner such that the front end portion of the inner spring is fixed to the clamp in a state where it is held between the sheath and the internal circumference of the clamp;
- the outer spring having a shorter length than that of the inner spring in the longitudinal direction of the multi-core cable is provided in a manner such that the front end portion of the outer spring is fixed to the outer circumference of the clamp;
- and
- the rubber boot covers the outer circumferences of the inner spring and the outer spring.
