Abstract
A multicore coaxial cable includes a conductor layer, an insulator layer surrounding the conductor layer, plastic tape surrounding the insulator and a metal shield surrounding the plastic tape. The exterior surface of the plastic tape is coated with a metal layer to contact the metal shield to reduce the electrostatic noises in the cable.
Claims7
A coaxial cable comprising:
- an electrical conductor;
- an insulator enclosing the conductor;
- a metal-coated plastic layer enclosing the insulator, the layer having an interior surface made of a non-metallic layer integrated with the insulator, and having an exterior surface made of a metallic layer not less than 0.2 .mu.m thick;
- a metal shield enclosing the metal-coated plastic layer and contacting the exterior surface of the metal-coated plastic layer.
1 more element
A coaxial cable comprising:
- an electrical conductor;
- an insulator enclosing said conductor;
- a plastic tape having an exterior surface coated with a metal layer, said plastic tape being wound around and integrated with said insulator;
- and
- a metal shield enclosing said plastic tape so that said metal layer of said plastic tape comes into contact with said metal shield, said metal shield comprising a spiral covering about said plastic tape.
2 more elements
A multi-core cable comprising:
- a plurality of coaxial shielded cables each including an electrical conductor;
- and
- a plurality of insulators enclosing said conductors in a one-to-one correspondence, a plurality of plastic tapes having exterior surfaces coated with metal layers not less than 0.2 .mu.m thick and being wound around and integrated with said insulators in a one-to-one correspondence;
- and
- a plurality of metal shields enclosing said plastic tapes on a one-to-one correspondence so that said metal layers of said plastic tapes come into contact with said corresponding metal shields.
