Abstract
A composite dielectric coaxial cable which is easily hand-strippable for termination without disturbing its drain wire or unravelling the metallized tape comprising its shielding layer.
Claims9
A coaxial electric signal cable comprising:
- (a) a core consisting of a metal center conductor surrounded by a first layer of tape-wrapped expanded polytetrafluoroethylene insulation, then a second layer of polymeric insulation, wherein the second layer of insulation is in intimate contact with, but not adhered to, the first layer;
- (b) a conductive metal drain wire arranged parallel to said core;
- (c) an outer conducting layer surrounding said core and said drain wire, comprising a helically-wrapped metal-coated polymer tape, metal side contacting said drain wire, and having a strip of heat-sealable adhesive on an edge of said tape on the same side of the tape as that bearing said metal;
- and
- (d) a protective jacket;
- wherein the outer portion of said first layer of insulation is sintered to thermoset after wrapping.
