Abstract

Abstract A high frequency noise prevention cable comprising a nonmetallic filament coated with a conductive and magnetic coating layer composed of one selected from the group of a magnetic metal, metallic oxide and metallic silicate, which may be employed alone except the metal or in combination, and nonmetallic particles dispersed in a binding agent of a high frequency inductive synthetic resin or synthetic rubber; a conductive non-metallic filament having a film of conductive nonmetallic particles such as carbon, graphite etc. dispersed in a binding agent of a high frequency inductive synthetic resin or synthetic rubber and of more favorable electric conductivity than the former conductive and magnetic coating layer, said first nonmetallic filament being wrapped with said second non-metallic filament; a conductive, magnetic and flexible coating layer composed of one selected from the group of a magnetic metal, metallic oxide and metallic silicate, which may be employed alone except the metal or in combination, and conductive non-metallic particles such as carbon, graphite etc. dispersed in a binding agent of vulcanized rubber, said conductive, magnetic and flexible coating layer being formed around said wrapped nonmetallic filament; and a rubber coating having an insulating property and another rubber coating for protection being formed therearound. Such 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.
