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.

Claims (27)

1. 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.

2. The cable according to claim 1 , wherein the tinsel copper further comprises a plating film on a surface of the tinsel copper.

3. The cable according to claim 1 , wherein the cable has a flex resistance property of no disconnection after flexions for 500,000 or more times by a predetermined flex resistance property test, a torsion durability of no disconnection after torsion for 500,000 or more times by a predetermined torsion durability test, and a cable tensile property of 1000 N or more by a predetermined cable tensile property test.

4. The cable according to claim 1 , wherein the cable is configured to be used for at least one of signal supply and power supply for electric and electronic components installed in a vehicle.

5. 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.

6. The cable according to claim 1 , wherein the reinforcing layer abuts the sheath.

7. The cable according to claim 6 , wherein the reinforcing layer abuts the shield layer.

8. The cable according to claim 1 , wherein the shield layer abuts the insulating layer of the insulated wire.

9. The cable according to claim 1 , wherein the fiber comprises polyvinyl alcohol.
