Abstract
A cable assembly includes a cable having a core surrounded by a sheath. A cone element has an interior bore receiving the cable core, and has a tapered exterior surface. At least a portion of the cone is received within the cable sheath. A cup has a tapered bore receiving the sheath and the core. A portion of the sheath is captured between the exterior of the cone and the interior of the cup bore. Tension applied to the cable with respect to cup generates compression of the sheath between the cone and cup, and tension is thus transmitted by the sheath without application of radial force to the core. The sheath may include a strength member such as a braided metal wrap, and an elastic jacket, so that the wrap bears the tension, and the jacket returns the sheath to its normal length upon cessation of tension.
Claims26
A cable assembly comprising:
- a cable comprising a core surrounded by a sheath;
- a cone element defining a bore receiving the core;
- the cone having a tapered exterior surface;
- at least a portion of the cone being received within the sheath;
- a cup defining a tapered cup bore receiving the sheath and the core;
- a portion of the sheath captured between the exterior of the cone and the cup bore;
- and
- the cone defining an axis and having a axial length, and wherein the tapered exterior surface of the cone extends the entire axial length of the cone.
A cable assembly comprising:
- a cable comprising a core surrounded by a sheath;
- a cone element defining a bore receiving the core;
- the cone having an exterior surface having a smaller diameter at one end than at the other end;
- the entire cone being received within the sheath;
- a cup defining a cup bore receiving the sheath and the core, the bore of the cup having a smaller diameter at one end than at the other end;
- a portion of the sheath captured between the exterior of the cone and the cup bore;
- the one end of the cone having an exterior surface having a smaller diameter, and the one end of the large end of the bore of the cup having a smaller diameter, extending in a common direction;
- and
- wherein the smaller diameter end of the cone extends toward an intermediate portion of the cable and away from a free end of the cable adjacent the cone.
A cable assembly comprising:
- a cable comprising a core surrounded by a sheath;
- a cone element defining a bore receiving the core;
- the cone having a tapered exterior surface;
- at least a portion of the cone being received within the sheath;
- a cup defining a tapered cup bore receiving the sheath and the core;
- a portion of the sheath captured between the exterior of the cone and the cup bore;
- a largest diameter portion of the tapered exterior surface of the cone comprising the largest diameter portion of the entire cone;
- and
- the cone having a smaller diameter end extending toward an intermediate portion of the cable and away from a free end of the cable adjacent the cone.
