HIGH SPEED DIFFERENTIAL CABLE, HIGH SPEED DIFFERENTIAL ROLLER-SCREEN CABLE, HIGH SPEED DIFFERENTIAL ROUND SHAPE MULTI-TWIN CABLE

摘要

PROBLEM TO BE SOLVED: To provide a high speed differential cable, a high speed differential roller screen cable, and a high speed differential round shape multi-twin cable suppressing the finished outer diameter small in spite of forming the constitution of the cable taking out data transmission capacity at the maximum.;SOLUTION: Signal wires 4a, 4b manufactured by installing dielectric layers 2a, 2b and skin layers 3, 3 around center conductors 1, 1 respectively are arranged so as to make twin cores parallel. Drain wires 5a, 5b having smaller diameter than that of the center conductor 1 are arranged on each outside of the signal wires 4a, 4b, and while four-core flat structure is kept, a metal laminated tape or a metal vapor deposition tape is wound or longitudinally attached to form an outside conductor 6, and then the outside conductor 6 is covered with a jacket layer 7 to manufacture the high speed differential cable 10.;COPYRIGHT: (C)2002,JPO
