Guarded coaxial cable assembly
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.
1. A flexible cord that is a crush resistant electrical cord comprising:
a 75 ohm microcoaxial cable including a center conductor, a conductive shield around the center conductor, a dielectric between the center conductor and the conductive shield, and an insulating cover around the shield;
two electrically conductive rails made from copper or a copper alloy;
the microcoaxial cable located between the two rails;
the rails for preventing harmful compression of the microcoaxial cable;
the microcoaxial cable and the rails extending side-by-side within a substantially flat jacket having a major cross-sectional dimension with opposed major sides and a minor cross-sectional dimension with opposed minor sides;
the rails configured to protect the microcoaxial cable when the opposed major sides are subjected to forces tending to crush the microcoaxial cable;
the cord located between a sash or door and a mated sash or door frame; and,
the cord bent in a “U” shape, the major sides being pressed together by sash or door closing forces;
wherein the rails cause the cord to substantially retain deformations.
2. The cord of claim 1 wherein the cross-section of the cord is not trapezoidal, but about rectangular, the minor sides being curved.
3. The cord of claim 1 wherein the major sides are of equal length, the minor sides adjoining the major sides.
