Abstract
A flexible shielded cable that employs a thin metallic foil or plastic metallic foil tape having a metal surface wherein the metallic foil or metal surface is less than 0.0030 inches in thickness disposed about a layer of dielectric material and disposed within a metallic serve or braid. The thin metallic foil prevents or reduces relative movement of the dielectric and the conductor core disposed therein relative to the braid. Preferably, either the metallic foil or braid is a noncopper metal.
Claims14
A flexible shielded cable comprising:
- at least one elongated flexible metal conductor;
- a layer of flexible dielectric material disposed about said conductor;
- a thin foil disposed about said layer of flexible dielectric material, said thin foil being selected from a copper foil tape, a copper composite tape and a conductive epoxy, said copper foil tape, the copper layer on said copper composite tape or the conductive epoxy having a thickness of less than 0.0030 inches;
- a metallic braid disposed about said thin foil;
- a layer of bonding agent bonding said braid and said thin foil;
- and
- said metallic braid is selected from the group consisting of bronze, plated bronze, nickel, plated nickel, silver, and gold.
