Abstract
A high-speed transmission cable includes two parallel signal lines for transmitting a differential signal, an insulation collectively covering the two signal lines, a shield conductor covering the insulation, and a ground connecting drain wire. The drain wire is arranged so that a portion of the outer circumference thereof covered with the insulation is held by the insulation, another portion of the outer circumference not covered with the insulation protrudes outward from the insulation and the protruding portion is electrically in contact with the shield conductor.
Claims10
A high-speed transmission cable, comprising:
- two parallel signal lines for transmitting a differential signal;
- an insulation collectively covering the two signal lines;
- a shield conductor covering the insulation;
- and
- a ground connecting drain wire,
- wherein the drain wire is arranged so that a portion of the outer circumference thereof covered with the insulation is held by the insulation, another portion of the outer circumference not covered with the insulation protrudes outward from the insulation and the protruding portion is electrically in contact with the shield conductor.
A method of manufacturing a high-speed transmission cable, comprising:
- covering two parallel signal lines for transmitting a differential signal and a ground connecting drain wire with an insulation;
- removing a portion of the insulation so that a portion of the outer circumference of the drain wire protrudes outwards from the insulation;
- and
- providing a shield conductor to cover the insulation so that the shield conductor is electrically in contact with the protruding portion of the drain wire.
A method of manufacturing a high-speed transmission cable, comprising:
- covering two parallel signal lines for transmitting a differential signal and a dummy wire with an insulation;
- removing a portion of the insulation and taking the dummy wire out from the insulation;
- fitting a ground connecting drain wire into a recess on the insulation produced by taking out the dummy wire so that the drain wire is held by the insulation and a portion of the outer circumference of the drain wire protrudes outwards from the insulation;
- and
- providing a shield conductor to cover the insulation so that the shield conductor is electrically in contact with the protruding portion of the drain wire.
