Abstract
A shielded cable includes an inner conductor, an insulation covering an outer periphery of the inner conductor, and an outer conductor covering an outer periphery of the insulation. The outer conductor includes a first outer conductor covering the outer periphery of the insulation and including a served shield with first element wires spirally wound, and a second outer conductor covering an outer periphery of the first outer conductor and including a braided shield with second element wires braided.
Claims23
A shielded cable, comprising,
- an inner conductor;
- an insulation comprising an extrusion coating covering an outer periphery of the inner conductor, the extrusion coating comprising a material selected from the group consisting of perfluoro ethylene propene copolymer (FEP), perfluoroalkoxy alkane (PFA), polyethylene (PE), polypropylene (PP), foamed PE, and foamed PP;
- and
- an outer conductor covering an outer periphery of the insulation,
- wherein the outer conductor comprises:
- a first outer conductor covering directly the outer periphery of the insulation and comprising a served shield with first element wires spirally wound;
- and
- a second outer conductor covering an outer periphery of the first outer conductor and comprising a braided shield with second element wires braided, and the first outer conductor is pressed inside by the second outer conductor in a radial direction,
- wherein the first outer conductor consists of the served shield with first element wires spirally wound directly covering the outer periphery of the insulation,
- wherein the first element wires are not coated by a lubricant oil, and the second element wires are coated by a lubricant oil,
- wherein the first element wires comprise a copper alloy wire including a surface that is silver-plated, and
- wherein the second element wires comprise a copper alloy wire including a surface that is tin-plated.
