Abstract

A cable with braided shield includes a conductor, an insulation layer arranged to cover a periphery of the conductor, a braided shield layer arranged to cover a periphery of the insulation layer, and a sheath arranged to cover a periphery of the braided shield layer. The braided shield layer includes an inner braided shield layer, and an outer braided shield layer provided on a periphery of the inner braided shield layer. The inner braided shield layer includes a braided shield braided to cross metal wires. The outer braided shield layer includes a braided shield braided to cross a copper tinsel wire and a metal wire.

Claims

1. A cable with braided shield, comprising:

a conductor;

an insulation layer arranged to cover a periphery of the conductor;

a braided shield layer arranged to cover a periphery of the insulation layer; and

a sheath arranged to cover a periphery of the braided shield layer,

wherein the braided shield layer comprises an inner braided shield layer, and an outer braided shield layer provided on a periphery of the inner braided shield layer,

wherein the inner braided shield layer comprises a braided shield braided to cross metal wires,

wherein the outer braided shield layer comprise a braided shield braided to cross a copper tinsel wire and a metal wire, and

wherein the cable with braided shield satisfies D1>

D2, where D1 is an outer diameter of the copper tinsel wire of the outer braided shield layer, and D2 is an outer diameter of the metal wire of the outer braided shield layer.

4. The cable with braided shield according to claim 1, wherein a ratio D1/D2 of D1 to D2 is not less than 1.2 and not more than 2.5.

2. A cable with braided shield, comprising:

an inner conductor;

an insulation layer arranged to cover a periphery of the inner conductor;

an outer conductor comprising a braided shield layer arranged to cover a periphery of the insulation layer; and

a sheath arranged to cover a periphery of the outer conductor,

wherein the braided shield layer comprises an inner braided shield layer, and an outer braided shield layer provided on a periphery of the inner braided shield layer,

wherein the inner braided shield layer comprises a braided shield braided to cross metal wires,

wherein the outer braided shield layer comprises a braided shield braided to cross a copper tinsel wire and a metal wire, and

wherein the cable with braided shield satisfies D1>

D2, where D1 is an outer diameter of the copper tinsel wire of the outer braided shield layer, and D2 is an outer diameter of the metal wire of the outer braided shield layer.

5. The cable with braided shield according to claim 2, wherein a ratio D1/D2 of D1 to D2 is not less than 1.2 and not more than 2.5.

3. A cable with braided shield, comprising

a cable core comprising a plurality of insulated wires covered with an insulation layer on a conductor;

a braided shield layer covering a periphery of the cable core; and

a sheath arranged to cover a periphery of the braided shield layer,

wherein the braided shield layer comprises an inner braided shield layer, and an outer braided shield layer provided on a periphery of the inner braided shield layer,

wherein the inner braided shield layer comprises a braided shield braided to cross metal wires,

wherein the outer braided shield layer comprise a braided shield braided to cross a copper tinsel wire and a metal wire, and

wherein the cable with braided shield satisfies D1>

D2, where D1 is an outer diameter of the copper tinsel wire of the outer braided shield layer, and D2 is an outer diameter of the metal wire of the outer braided shield layer.

6. The cable with braided shield according to claim 3, wherein a ratio D1/D2 of D1 to D2 is not less than 1.2 and not more than 2.5.
