Abstract

A cable includes: a cable core including one or more electrical wires; a shield layer made of a metallic wire arranged on a periphery of the cable core; and a sheath arranged on a periphery of the shield layer. The metallic wire is made of a copper alloy wire made of a copper alloy containing indium, a content of which is equal to or more than 0.3 mass % and equal to or less than 0.65 mass %, and the metallic wire has tensile strength that is equal to or higher than 350 MPa and elongation that is equal to or higher than 7%.

Claims (20)

1. A cable comprising:

a cable core including one or more electrical wires;

a shield layer made of a metallic wire arranged on a periphery of the cable core; and

a sheath arranged on a periphery of the shield layer,

wherein the metallic wire is a copper alloy wire

which is made of a copper alloy containing equal to or more than 0.3 mass % and equal to or less than 0.65 mass % indium and equal to or more than 0.02 mass % and less than 0.1 mass % tin, with the remainder consisting of copper and unavoidable impurities, and

the metallic wire has tensile strength that is equal to or higher than 350 MPa and elongation that is equal to or higher than 7%.

2. The cable according to claim 1 ,

wherein the copper alloy wire is made of a copper alloy containing tin, a content of which is equal to or more than 0.02 mass % and less than 0.1 mass %, and

a total content rate of the indium and the tin is equal to or less than 0.65 mass %.

3. The cable according to claim 1 ,

wherein the metallic wire is made of a plated wire including a plating layer arranged on a periphery of the copper alloy wire, and

the metallic wire has tensile strength that is equal to or higher than 350 MPa and elongation that is equal to or higher than 7%.

4. The cable according to claim 1 ,

wherein the metallic wire has an electrical conductivity that is equal to or higher than 70% IACS.

5. The cable according to claim 1 ,

wherein the shield layer is made of a braided shield having a braid density that is equal to or higher than 85% and a braid angle that is equal to or smaller than 40 degrees.

6. The cable according to claim 1 ,

wherein the unavoidable impurities in the copper alloy are one or more of the following elements: aluminum, silicon, phosphorus, sulfur, chromium, iron, nickel, arsenic, selenium, silver, antimony, lead, and bismuth, and,

the total content of the unavoidable impurities in the copper alloy is equal to or more than 0.002 mass % and equal to or less than 0.003 mass %.
