Abstract

A conductive cable clamp is provided which may be attached to an end region of a coaxial cable in such a manner that a portion of the cable clamp penetrates the outer insulative jacket of the coaxial cable and contacts the ground wire braid of the coaxial cable. Such ground wire braid is severed at the end of the coaxial cable rather than being folded back towards the outer surface of the outer insulative jacket in the usual manner.

Claims

1. A coaxial cable assembly, comprising:

a coaxial cable having an outer insulative jacket, a center conductor and a ground wire braid therebetween, said outer insulative jacket and said ground wire braid terminating at an end of said coaxial cable, and said center conductor including a length which extends beyond said end;

a conductive cable clamp having a bore extending therethrough, said coaxial cable having an end region which extends into said bore, said cable clamp comprising a first component which extends in a direction of a longitudinal axis of said cable clamp from a first end to an opposite second end, and a second component which extends from said first end in a direction of said longitudinal axis, said second component comprising a portion which penetrates said outer insulative jacket and engages said ground wire braid, and a connector shell attached to said end region, said connector shell being formed for longitudinally slidable, torque-free engagement with said penetrating portion, said penetrating portion being in contact with and sandwiched between said ground wire braid and said connector shell.

2. The conductive cable clamp of claim 1 wherein said second component comprises a segment comprising a first length extending away from said longitudinal axis to a juncture, and a second length extending towards said longitudinal axis from said juncture to a distal end.

3. The conductive cable clamp of claim 1 wherein said second component comprises a plurality of segments each of which comprises a first length extending away from said longitudinal axis to a juncture, and a second length extending towards said longitudinal axis from said juncture to a distal end.

4. The conductive cable clamp of claim 3 wherein each segment of said plurality of segments is spaced from an adjacent segment in a circumferential direction relative to said longitudinal axis.

5. The conductive cable clamp of claim 4 wherein said plurality of segments are equally spaced in said circumferential direction.

6. The conductive cable clamp of claim 3 wherein an inner surface of said first component lies in a first cylindrical plane and each distal end of said plurality of segments lies in a second cylindrical plane which is concentric with said first cylindrical plane, the diameter of said first cylindrical plane being (a) less than the diameter of said second cylindrical plane when said cable clamp is in an inoperative mode and (b) more than the diameter of said second cylindrical plane when said cable clamp is in an operative mode.

7. The conductive cable clamp of claim 1 wherein said first component is generally cylindrical.

8. The conductive cable clamp of claim 1 wherein said portion comprises a sharp edge.

9. The coaxial cable assembly of claim 1 wherein said second component comprises a segment comprising a first length extending away from said longitudinal axis to a juncture, and a second length extending towards said longitudinal axis from said juncture to a distal end.

10. The coaxial cable assembly of claim 1 wherein said second component comprises a plurality of segments each of which comprises a first length extending away from said longitudinal axis to a juncture, and a second length extending towards said longitudinal axis from said juncture to a distal end.

11. The coaxial cable assembly of claim 10 wherein each segment of said plurality of segments is spaced from an adjacent segment in a circumferential direction relative to said longitudinal axis.

12. The coaxial cable assembly of claim 11 wherein said plurality of segments are equally spaced in said circumferential direction.

13. The coaxial cable assembly of claim 12 wherein said first component is generally cylindrical.

14. The coaxial cable assembly of claim 1 wherein an inner surface of said first component lies in a first cylindrical plane and each distal end of said plurality of segments lies in a second cylindrical plane which is concentric with said first cylindrical plane, the diameter of said first cylindrical plane being (a) less than the diameter of said second cylindrical plane when said cable clamp is in an inoperative mode and (b) more than the diameter of said second cylindrical plane when said cable clamp is in an operative mode.

15. A coaxial cable assembly, comprising:

a conductive cable clamp having a bore extending therethrough formed to receive a coaxial cable, said cable clamp comprising a first component which extends in a direction of a longitudinal axis of said cable clamp from a first end to an opposite second end, and a second component which extends from said first end in a direction of said longitudinal axis, said second component comprising a portion which penetrates said outer insulative jacket and engages said ground wire braid, and a connector shell attached to said end region, said connector shell being formed for longitudinally slidable, torque-free engagement with said penetrating portion, said penetrating portion being in contact with and sandwiched between said connector shell and a ground wire braid when said coaxial cable assembly is installed on a coaxial cable.
