Abstract
A differential signal cable includes a pair of signal line conductors for transmitting differential signals, an insulation collectively covering the pair of signal line conductors, a shielding tape wrapped around the insulation, and an insulating tape wound around the shielding tape. A gap is formed between an outer peripheral surface of the insulation and an inner surface of the shielding tape such that the insulation is movable relative to the shielding tape.
Claims15
A differential signal cable, comprising:
- a pair of signal line conductors for transmitting differential signals;
- an insulation collectively covering the pair of signal line conductors;
- a shielding tape wrapped around the insulation;
- and
- an insulating tape wound around the shielding tape,
- wherein a gap is formed between an outer peripheral surface of the insulation and an inner surface of the shielding tape such that the insulation is movable relative to the shielding tape,
- wherein the insulation comprises, in a cross-section thereof orthogonal to an extending direction of the differential signal cable, an ellipse shape that has a major axis in an alignment direction of the pair of signal line conductors,
- wherein the gap is formed, along the major axis, between each of end portions of the insulation and the shielding tape, and
- wherein, along the major axis, a sum of a width of the gap formed between the end portions of the insulation and the shielding tape is from 10 μm to 20 μm.
