Abstract

A wire harness includes electric wires, and an electromagnetic wave suppression member that includes a restricting member and an annular magnetic core, the restricting member being provided to cover a periphery of the electric wires and including an inner wall portion more rigid than the electric wires, and the magnetic core being provided around the inner wall portion. The restricting member includes fixing portions formed to fix the electromagnetic wave suppression member to a fixing target.

First claim

What is claimed is:

1. A wire harness, comprising:
electric wires; and
an electromagnetic wave suppression member that comprises a restricting member and an annular magnetic core, the restricting member being provided to cover a periphery of the electric wires and comprising an inner wall portion more rigid than the electric wires, and the magnetic core being provided around the inner wall portion,
wherein the restricting member comprises fixing portions formed to fix the electromagnetic wave suppression member to a fixing target.

2. The wire harness according to claim 1 , wherein the magnetic core comprises a nanocrystalline soft magnetic material.

3. The wire harness according to claim 1 , wherein the inner wall portion is configured to hold the electric wires.

4. The wire harness according to claim 3 , wherein a braided shield is provided around the electric wires, and the inner wall portion is in contact with the braided shield and holds the electric wires via the braided shield.

5. The wire harness according to claim 1 , wherein the restricting member comprises a cylindrical outer wall portion and a restricting portion, the outer wall portion covering the inner wall portion and the magnetic core such that the magnetic core is sandwiched between the inner and outer wall portions, and the restricting portion preventing the magnetic core from falling through between the inner and outer wall portions.

6. The wire harness according to claim 1 , wherein the magnetic core is formed to cover all of the plurality of electric wires.

7. The wire harness according to claim 1 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.

8. The wire harness according to claim 2 , wherein the inner wall portion is configured to hold the electric wires.

9. The wire harness according to claim 2 , wherein the restricting member comprises a cylindrical outer wall portion and a restricting portion, the outer wall portion covering the inner wall portion and the magnetic core such that the magnetic core is sandwiched between the inner and outer wall portions, and the restricting portion preventing the magnetic core from falling through between the inner and outer wall portions.

10. The wire harness according to claim 3 , wherein the restricting member comprises a cylindrical outer wall portion and a restricting portion, the outer wall portion covering the inner wall portion and the magnetic core such that the magnetic core is sandwiched between the inner and outer wall portions, and the restricting portion preventing the magnetic core from falling through between the inner and outer wall portions.

11. The wire harness according to claim 4 , wherein the restricting member comprises a cylindrical outer wall portion and a restricting portion, the outer wall portion covering the inner wall portion and the magnetic core such that the magnetic core is sandwiched between the inner and outer wall portions, and the restricting portion preventing the magnetic core from falling through between the inner and outer wall portions.

12. The wire harness according to claim 2 , wherein the magnetic core is formed to cover all of the plurality of electric wires.

13. The wire harness according to claim 3 , wherein the magnetic core is formed to cover all of the plurality of electric wires.

14. The wire harness according to claim 4 , wherein the magnetic core is formed to cover all of the plurality of electric wires.

15. The wire harness according to claim 5 , wherein the magnetic core is formed to cover all of the plurality of electric wires.

16. The wire harness according to claim 2 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.

17. The wire harness according to claim 3 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.

18. The wire harness according to claim 4 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.

19. The wire harness according to claim 5 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.

20. The wire harness according to claim 6 , wherein the restricting member integrally comprises a housing portion for housing the magnetic core and a movement-restricting portion fixed to the electric wires or to a member covering the electric wires, and the housing portion and the movement-restricting portion are aligned along a longitudinal direction of the electric wires.
