Abstract

A shield conduction path that includes a wire; and a pipe with a circular cross-section that accommodates the wire. The pipe is formed by combining a first divided body and a second divided body that are divided in a diameter direction using, as boundaries, divided surfaces that extend in an axial direction of the pipe. The first divided body and the second divided body include a metal material that can be held in a combined state through welding, and a circumferential length of the first divided body is set to be longer than a circumferential length of the second divided body.

First claim

The invention claimed is:

1. A shield conduction path, comprising:
a wire; and
a pipe with a circular cross-section that accommodates the wire, wherein:
the pipe is formed by combining a first divided body and a second divided body that are divided in a diameter direction using, as boundaries, divided surfaces that extend in an axial direction of the pipe,
the first divided body and the second divided body include a metal material that can be held in a combined state through welding,
a circumferential length of the first divided body is set to be longer than a circumferential length of the second divided body,
the wire is stored in the first divided body,
the pipe is circular in cross section, and
a circumferential length of an outer curved surface of the first divided body is set to be longer that a circumferential length of an outer curved surface of the second divided body.

2. The shield conduction path according to claim 1 , wherein the first divided body has a form in which a virtual plane connecting the divided surfaces intersects with none of a plurality of the wires in a state in which the plurality of wires are accommodated in the first divided body.

3. The shield conduction path according to claim 1 , wherein a blocking protrusion with a form that protrudes in a circumferential direction from an edge on an inner circumferential side of the divided surface is formed on at least one of the first divided body and the second divided body.

4. The shield conduction path according to claim 3 , wherein a surface of the blocking protrusion that faces an inner portion of the pipe is an arc-shaped surface.

5. The shield conduction path according to claim 3 , wherein the blocking protrusion is formed on an inner circumferential surface of the at least one of the first divided body and the second divided body such that the blocking protrusion extends further diametrically inward than remaining parts of the at least one of the first divided body and the second divided boy.

6. The shield conduction path according to claim 3 , wherein:
the blocking protrusion is formed on only the first divided body;
the blocking protrusion has a semi-circular shape in the cross section;
the divided surface of the first divided body is flat in the cross section; and
the blocking protrusion circumferentially extends in two circumferential directions from the edge on the inner circumferential side of the divided surface.

7. The shield conduction path according to claim 1 , wherein on at least one of the first divided body and the second divided body, a pair of positioning portions that come into contact with a circumferential surface of the other divided body are formed.

8. The shield conduction path according to claim 1 , wherein there is only one divided surface along the diameter direction at each circumferential end of the first divided body and the second divided body.
