Abstract

In a method for manufacturing a wire harness, a process in which a metallic tube body is expanded in an exterior member to be an expanded state, so that an outer surface of an insulator comes into close contact with an inner surface of the exterior member is included.

Claims

1. A method for manufacturing a wire harness including a plurality of circuits and a tube body shaped exterior member which accommodates the plurality of circuits, wherein an outermost circuit of the plurality of circuits includes a metallic tube body and an insulator provided in an outer periphery side of the metallic tube body, the method comprising:

a process in which the metallic tube body is expanded in the tube body shaped exterior member to be in an expanded state, so that an outer surface of the insulator comes into close contact with an inner surface of the tube body shaped exterior member,

wherein expanding the metallic tube body in the tube body shaped exterior member includes;

inserting the metallic tube body, in an unexpanded state, into the tube body shaped exterior member to an inserted longitudinal position relative to the tube body shaped exterior member, and

after insertion to the inserted longitudinal position, expanding, while the metallic tube body remains at the inserted longitudinal position within the tube body shaped exterior member, the metallic tube body to the expanded state, wherein a radius of an interior hollow portion of the metallic tube body is greater in the expanded state than in the unexpanded state.

2. The method of claim 1, wherein each of the plurality of circuits includes a circular cross-section, the circular cross-sections of the plurality of circuits being concentric.

3. The method of claim 1, wherein the outermost circuit including the metallic tube body is a high-voltage circuit.

4. The method of claim 1, wherein the metallic tube body and the insulator have a length extending from an end of the tube body shaped exterior member and an end of the metallic tube body is exposed to form an electrically connecting part.

5. The method of claim 1, wherein the tube body shaped exterior member is formed of metal.

6. The method of claim 1, wherein the tube body shaped exterior member is formed of resin.

7. The method of claim 1, further comprising inserting another circuit of the plurality of circuits into the metallic tube body after the metallic tube body has been expanded to the expanded state.

8. The method of claim 1, wherein an inner surface of the outermost circuit of the plurality of circuits surrounds an outermost surface of another circuit of the plurality of circuits.
