Abstract

A guarded coaxial cable assembly provides at least one bundled electrical cable with first and second concentrically aligned conductors, the bundle encapsulated in a flexible jacket that is abrasion resistant and wherein with respect to a jacket cross-section a height of the jacket is smaller than a width of the jacket.

First claim

What is claimed is:

1. A crush resistant electrical cable method comprising the steps of:
providing at least one bundle including an electrical insulator between a single central conductor and an outer conductor;
concentrically aligning the central conductor, insulator, and outer conductor as a cylinder with a circular cross section;
configuring the bundle for conducting radio frequency signals in cable television and satellite television systems;
encapsulating the at least one bundle centrally within a polymeric jacket that is flexible, non-conducting, and abrasion resistant;
wherein with respect to a cross-section of the jacket a height of the jacket is smaller than a width of the jacket; and,
wherein a width of the at least one bundle is less than half of the width of the jacket.

2. The method of claim 1 further comprising the steps of:
at a first end of the bundle, affixing a female F-type coaxial connector to a first end of the central conductor; and,
at a second end of the bundle, affixing a female F-type coaxial connector to a second end of the central conductor.

3. The method of claim 2 wherein a ratio of the jacket height to the jacket width is between ⅓ and 1/10.

4. The method of claim 3 wherein the at least one bundle enables a 180 degree bend in the crush resistant electrical cable.

5. The method of claim 4 wherein the at least one bundle comprises a characteristic impedance of approximately 75 Ohms impedance and wherein the at least one bundle is configured to transmit signals with frequencies of at least 2 GHz.

6. The method of claim 1 further comprising the step of constructing the outer conductor to include at least one braid layer.

7. The method of claim 6 further comprising the step of affixing F-type connectors to opposite ends of the outer conductor.

8. The method of claim 7 further comprising the step of affixing F-type connectors to opposite ends of the central conductor.

9. The method of claim 8 further comprising the step of including a metal rail alongside the bundle and within the polymeric jacket.

10. The method of claim 9 further comprising the step of affixing F-Type connectors to the metal rail.

11. The method of claim 9 wherein with respect to a cross-section of the jacket, a ratio of jacket height to jacket width is in the range of ⅓ to 1/10.

12. The method of claim 11 wherein signal transmission through the cable is protected by the rail when a middle of the cable is pressed between portions of a closed window or a closed door.
