Abstract

A wire harness includes a wire portion having three wires arranged in the same direction, connectors connected to both end portions of the wire portion, a middle portion installed in an intermediate position of the wire portion between the connectors, a wire-side surge reducing section provided in the wire portion, a connector-side surge reducing section provided in each of the connectors, and a middle portion-side surge reducing section provided in the middle portion.

First claim

What is claimed is:

1 . A wire harness comprising:
a wire portion having three or more wires arranged in the same direction; connectors connected to end portions of the wire portion; a wire-side surge reducing section provided in the wire portion to reduce a surge voltage; and a connector-side surge reducing section provided in each of the connectors to reduce the surge voltage.

2 . The wire harness according to claim 1 , further comprising:
a middle portion installed in an intermediate position of the wire portion between the connectors; and a middle portion-side surge reducing section provided in the middle portion to reduce the surge voltage.

3 . A wire harness comprising:
a wire portion having three or more wires arranged in the same direction; connectors connected to end portions of the wire portion; and a middle portion installed in an intermediate position of the wire portion between the connectors, wherein the wire harness includes any one of: a group of a wire-side surge reducing section provided in the wire portion to reduce a surge voltage and a middle portion-side surge reducing section provided in the middle portion to reduce the surge voltage; and a group of a connector-side surge reducing section provided in each of the connectors to reduce the surge voltage and the middle portion-side surge reducing section.

4 . The wire harness according to claim 1 , further comprising:
a shield member collectively surrounding an outer circumferential side of the wire portion, wherein the wire-side surge reducing section includes a first wire holding member maintaining arrangement of the wires around a central axial line of the wire portion, each of the wires of the wire portion includes a conductor and an insulator coating an outer circumference of the conductor, and the first wire holding member includes: an external form maintaining portion surrounding a further outer circumferential side of the wire portion and the shield member; and a plurality of shield member form correcting portions formed such that each of the shield member form correcting portions projects from an inner circumferential surface of the external form maintaining portion in a direction of the central axial line between two wires of the wire portion adjacent to each other along a circumferential direction around the central axial line, and the shield member approaches a side of the central axial line from an outer circumferential-side tangent connecting the conductors of the two wires on a cross section viewed from an axial direction along the central axial line.

5 . The wire harness according to claim 2 , further comprising:
a shield member collectively surrounding an outer circumferential side of the wire portion, wherein the wire-side surge reducing section includes a first wire holding member maintaining arrangement of the wires around a central axial line of the wire portion, each of the wires of the wire portion includes a conductor and an insulator coating an outer circumference of the conductor, and the first wire holding member includes: an external form maintaining portion surrounding a further outer circumferential side of the wire portion and the shield member; and a plurality of shield member form correcting portions formed such that each of the shield member form correcting portions projects from an inner circumferential surface of the external form maintaining portion in a direction of the central axial line between two wires of the wire portion adjacent to each other along a circumferential direction around the central axial line, and the shield member approaches a side of the central axial line from an outer circumferential-side tangent connecting the conductors of the two wires on a cross section viewed from an axial direction along the central axial line.

6 . The wire harness according to claim 3 , further comprising:
a shield member collectively surrounding an outer circumferential side of the wire portion, wherein the wire-side surge reducing section includes a first wire holding member maintaining arrangement of the wires around a central axial line of the wire portion, each of the wires of the wire portion includes a conductor and an insulator coating an outer circumference of the conductor, and the first wire holding member includes: an external form maintaining portion surrounding a further outer circumferential side of the wire portion and the shield member; and a plurality of shield member form correcting portions formed such that each of the shield member form correcting portions projects from an inner circumferential surface of the external form maintaining portion in a direction of the central axial line between two wires of the wire portion adjacent to each other along a circumferential direction around the central axial line, and the shield member approaches a side of the central axial line from an outer circumferential-side tangent connecting the conductors of the two wires on a cross section viewed from an axial direction along the central axial line.

7 . The wire harness according to claim 4 , wherein
the wires of the wire portion have circular shapes on the cross section and are disposed at equal intervals along the circumferential direction, and the shield member form correcting portions of the first wire holding member are formed such that the shield member approaches 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 on the cross section.

8 . The wire harness according to claim 5 , wherein
the shield member form correcting portions of the first wire holding member are formed such that the shield member approaches up to the central axial line from between the two wires on the cross section to surround respective outer circumferential sides of the wires of the wire portion.

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

10 . The wire harness according to claim 7 , wherein
the shield member is grounded.

11 . The wire harness according to claim 8 , wherein
the shield member is grounded.

12 . The wire harness according to claim 1 , wherein
the wire-side surge reducing section includes a second wire holding member maintaining arrangement around the central axial line of the respective wires of the wire portion, and the second wire holding member includes: a main body portion formed in a cylindrical shape using the central axial line as an axial center; a plurality of wire housing portions provided to separately penetrate the main body portion along the central axial line, formed to be able to separately accommodate the wires, and disposed at equal intervals along the circumferential direction around the central axial line on the cross section viewed from the axial direction along the central axial line; and a space portion formed to penetrate the main body portion along the central axial line between two wire housing portions adjacent to each other along the circumferential direction among the plurality of wire housing portions.

13 . The wire harness according to claim 2 , wherein
the wire-side surge reducing section includes a second wire holding member maintaining arrangement around the central axial line of the respective wires of the wire portion, and the second wire holding member includes: a main body portion formed in a cylindrical shape using the central axial line as an axial center; a plurality of wire housing portions provided to separately penetrate the main body portio
