Abstract
A cable has a core made of an insulated wire, a shield layer provided at an outer periphery of the core, a reinforcing layer provided at an outer periphery of the shield layer, and a sheath provided at an outer periphery of the reinforcing layer. The insulated wire has a wire conductor and an insulating layer covering an outer periphery of the wire conductor. The shield layer is formed from tinsel-coppers. Each of the tinsel-copper has a core string and a copper foil provided around the core string. The reinforcing layer is formed by braiding fibers.
Claims9
A cable, comprising:
- a core comprising an insulated wire, the insulated wire comprising a wire conductor and an insulating layer covering an outer periphery of the wire conductor;
- a shield layer provided at an outer periphery of the core, the shield layer comprising a tinsel copper comprising a core string and a copper foil provided around the core string;
- a reinforcing layer provided at an outer periphery of the shield layer, the reinforcing layer comprising a braid of a fiber;
- and
- a sheath provided at an outer periphery of the reinforcing layer,
- wherein the shield layer comprises a braid of the tinsel copper;
- wherein the fiber comprises at least one material selected from the group consisting of polyvinyl alcohol, polyethylene terephthalate, and polyethylene-2,6-naphthalate,
- wherein the sheath comprises at least one rubber material selected from the group consisting of ethylene-propylene-diene rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, and chloroprene rubber, and
- wherein the reinforcing layer comes into contact with the sheath.

A cable, comprising:
- a core comprising three pieces of an insulated wire, the insulated wire comprising a linear conductor and an insulating layer which covers an outer periphery of the conductor;
- a shield layer provided at an outer periphery of the core, which is formed by braiding tinsel coppers, each of the tinsel coppers comprising a core string comprising a fiber and a copper foil spirally wound around an outer periphery of the core string;
- a reinforcing layer provided at an outer periphery of the shield layer and having a braid structure formed by braiding a plurality of fibers;
- and
- a sheath provided at an outer periphery of the reinforcing layer,
- wherein the conductor comprises stranded pieces of Sn-plated copper alloy wire,
- wherein the insulating layer, which covers the outer periphery of the conductor, comprises polytetrafluoroethylene copolymer which comprises a fluororesin,
- wherein the core comprises three stranded pieces of the insulated wires,
- wherein the shield layer comprises a braid structure formed by braiding the tinsel coppers, said each of the tinsel coppers being formed by preparing a single string comprising polyethylene terephthalate (PET) as a core string and covering an outer periphery of the core string with a copper foil,
- wherein the reinforcing layer is formed by braiding a plurality of fibers, the fiber comprising polyvinyl alcohol, and
- wherein the sheath comprises ethylene-propylene-diene rubber.
