Definitions

  • an air-spaced coaxial cable which includes a centre conductor having on its outer surface a coating of material which possesses suificient mechanical strength to bind to the conductor any portions of conducting material which may otherwise project from the surface of the conductor.
  • a copper inner conductor 1 is provided with disc spacers 2 of polythene spaced along a copper outer conductor 3.
  • the outer conductor 3 is enclosed in a polythene sheath 4.
  • the inner conductor is coated, in this instance, with a polyvinyl acetal emulsion 5 having a thickness of less Patented July 19, 1966 than one ten thousandths of an inch.
  • the disc spacers 2 have slots 7 and central holes 8 of a smaller diameter than the conductor 1 so that the disc spacers 2 are sprung on to the conductor 1 by forcing the conductor 1 through the slots 7 into the holes 8.
  • the outer conductor 3 is formed by longitudinally folding a copper tape round the disc spacers 2 so that the longitudinal edges of the copper tape abut one another.
  • the polythene sheath 4 is extruded around the outer conductor 3.
  • the change in the impedance and attenuation caused by the coating 5 was found to be less than 0.1% of the impedance and attenuation of the same cable with an inner conductor not coated.
  • the polyvinyl acetal emulsion coating 5 may be replaced by a coating of any electrically conducting or insulating material which possesses sulficient mechanical strength to bind any portions of conducting material which may otherwise project from the surface of the conductor for example, the polyvinyl acetal coating may be replaced by a coating of an epoxy resin, 3. polystyrene composition, or copper plating.
  • An air-spaced coaxial cable which includes a centre conductor having on its outer surface a means for binding to the conductor any portions of conducting material which may otherwise project from the surface of the conductor, comprising a coating of a material which possesses sufiicient mechanical strength and a thickness not exceeding 0.0001 inch.
