  • a-cable is capable of preventing noises in every range of high frequency and is also capable of attaining a favorable electrical connection with a metallic terminal at the end thereof.
  • the conventional high frequency noise prevention cable is composed of a non-metallic conductor such as a filament simply dipped in colloidal alcoholic carrier of carbon particles to apply the carbon particles to the surface of the filament, a conductive rubber coating is applied thereto to prevent said particles from falling off and to give the filament flexibility, a mesh tissue is provided thereon and a conductive rubber layer further applied thereto on its outermost surface. Accordingly, in the cable thus obtained, when the rubber insulator is peeled off for attaching a metallic terminal to the end of the cable, the carbon particles applied to the surface of the filament easily fall off due to a mechanical stress, thereby causing a substantial reduction of conductivity.
  • Such corona discharge forms a film of metallic oxide on the surface of the metallic terminal, which causes an unfavorable conductivity between the conductor and the metallic terminal.
  • the conventional cable of this kind has a further defeet that it is effective in preventing the VHF noise, but scarcely any measures are taken to prevent the UHF noise.
