Abstract

A wire harness includes a wire portion formed by arranging three wires in the same direction, the respective wires having conductors and insulators coating outer circumferences of the conductors, and a braided wire. The three wires of the wire portion and the braided wire are disposed such that the braided wire is interposed between two wires of the wire portion adjacent to each other along a circumferential direction around a central axial line of the wire portion on a cross section of the wire harness when viewed from an axial direction along the central axial line, on a side of the central axial line from outer circumferential-side tangents connecting the conductors of the two wires.

First claim

What is claimed is:

1 . A wire harness comprising:
a wire portion formed by arranging three or more wires in the same direction, each of the wires having a conductor and an insulator coating an outer circumference of the conductor; and a shield member, wherein the three or more wires of the wire portion and the shield member are disposed such that the shield member is interposed between two wires of the wire portion adjacent to each other along a circumferential direction around a central axial line of the wire portion on a cross section of the wire harness when viewed from an axial direction along the central axial line, on a side of the central axial line from an outer circumferential-side tangent connecting the conductors of the two wires.

2 . The wire harness according to claim 1 , wherein
the shield member is a braided wire formed by weaving a metal thin wire in a mesh shape.

3 . The wire harness according to claim 1 , wherein
the shield member is grounded.

4 . The wire harness according to claim 2 , wherein
the shield member is grounded.

5 . The wire harness according to claim 1 , wherein
the wires of the wire portion have circular shapes on the cross section and are evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and approach the side of the central axial line from a segment connecting center of gravity points of two wires of the wire portion adjacent to each other in the circumferential direction between the two wires.

6 . The wire harness according to claim 2 , wherein
the wires of the wire portion have circular shapes on the cross section and are evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and approach the side of the central axial line from a segment connecting center of gravity points of two wires of the wire portion adjacent to each other in the circumferential direction between the two wires.

7 . The wire harness according to claim 3 , wherein
the wires of the wire portion have circular shapes on the cross section and are evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and approach the side of the central axial line from a segment connecting center of gravity points of two wires of the wire portion adjacent to each other in the circumferential direction between the two wires.

8 . The wire harness according to claim 5 , wherein
the shield member is formed to approach up to the central axial line from between the two wires on the cross section, and surround respective outer circumferential sides of the wires of the wire portion.

9 . The wire harness according to claim 1 , wherein
the wires of the wire portion have rectangular shapes on the cross section, the wires being disposed such that long sides of the rectangular shapes extend outward from the central axial line and being evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and is formed along an outer short side corresponding to one of two short sides of the rectangular shape of each of the wires and two long sides of the rectangular shape.

10 . The wire harness according to claim 2 , wherein
the wires of the wire portion have rectangular shapes on the cross section, the wires being disposed such that long sides of the rectangular shapes extend outward from the central axial line and being evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and is formed along an outer short side corresponding to one of two short sides of the rectangular shape of each of the wires and two long sides of the rectangular shape.

11 . The wire harness according to claim 3 , wherein
the wires of the wire portion have rectangular shapes on the cross section, the wires being disposed such that long sides of the rectangular shapes extend outward from the central axial line and being evenly disposed along the circumferential direction, and the shield member is formed to collectively surround an outer circumferential side of the wire portion on the cross section, and is formed along an outer short side corresponding to one of two short sides of the rectangular shape of each of the wires and two long sides of the rectangular shape.
