Abstract

A wire harness includes one or a plurality of high voltage conduction paths, each having a high voltage conduction path main body, and a terminal which is provided at an end of the high voltage conduction path main body. The high voltage conduction path main body is formed into a cylindrical shape by spirally winding a metal wire rod and an insulating wire rod, and side end surfaces, which face each other, of the metal wire rod and the insulating wire rod positioned to be adjacent to each other alternately, contact each other.

Claims

1. A wire harness comprising:

one or a plurality of conduction paths, each having a conduction path main body; and

a terminal which is provided at an end of the conduction path main body,

wherein the conduction path main body is formed into a cylindrical shape by spirally winding a metal wire rod and an insulating non-conductive rod, and side end surfaces, which face each other, of the metal wire rod and the insulating non-conductive rod positioned to be adjacent to each other alternately, contact each other.

2. The wire harness according to claim 1, wherein the conduction path includes a linear ferrite member;

and

wherein the ferrite member is inserted into a hollow part of the conduction path main body.

3. The wire harness according to claim 2, wherein the conduction path main body and the ferrite member have flexibility.

4. The wire harness according to claim 1, wherein the conduction path includes an insulator coated on an outer surface of the conduction path main body, and an exterior member which is provided outside the insulator.

6. The wire harness according to claim 1, the metal wire rod and the insulating non-conductive rod have different cross sectional shapes.

7. The wire harness according to claim 1, the metal wire rod has a triangular convex portion configured to fit with a triangular concave portion of the insulating non-conductive rod.

5. A wire harness comprising:

one or a plurality of conduction paths, each having a conduction path main body; and

a terminal which is provided at an end of the conduction path main body,

wherein the conduction path main body is formed into a cylindrical shape by spirally winding a metal wire rod and an insulating wire rod, and side end surfaces, which face each other, of the metal wire rod and the insulating wire rod positioned to be adjacent to each other alternately, contact each other,

wherein the terminal includes;

an inner terminal, which is located at an inner side of the conduction path main body and contacts an inner surface of the metal wire rod;

an outer terminal, which is located at an outer side of the conduction path main body and contacts an outer surface of the metal wire rod; and

an electrical contact part for external connection which is provided integrally with any of the inner terminal and the outer terminal.
