Abstract

A wire harness including: an electrically conducting path including an electrical wire having a front end portion to which a terminal fitting is fixed; a corrugated tube configured to enclose the electrical wire; a rubber boot that is attached to a front end portion of the corrugated tube and is configured to enclose the electrical wire; and an electrical wire holder that is provided with: a holding part configured to hold the electrical wire; and a locking part configured to be locked to a circumferential surface of the corrugated tube. It is possible to stabilize the positional relationship between the front end portion of the electrically conducting path and the front end portion of the rubber boot by holding the electrical wire with the electrical wire holder and locking the electrical wire holder to the circumferential surface of the corrugated tube.

First claim

The invention claimed is:

1. A wire harness comprising:
an electrically conducting path including an electrical wire having a front end portion to which a terminal fitting is fixed;
a corrugated tube enclosing the electrical wire;
a rubber boot that is attached to a front end portion of the corrugated tube and encloses the electrical wire; and
an electrical wire holder that is provided with: a holding part that holds the electrical wire, and a locking part;
wherein the locking part has a groove shape or a rib shape and locks to the circumferential surface of the corrugated tube.

2. The wire harness according to claim 1 ,
wherein the electrical wire holder includes a tube-shaped main body that is capable of enclosing the electrical wire,
the holding part is cantilever-shaped protruding in an axial direction from the tube-shaped main body, and
the holding part and the electrical wire are fixed together using an adhesive tape, the electrical wire being disposed along the holding part.

3. The wire harness according to claim 2 ,
wherein the holding part includes a dislodgment prevention part that is formed on a protruding end portion of the holding part and that protrudes in a direction that is opposite to a contact area of the holding part that is capable of coming into contact with the electrical wire.

4. The wires harness according to claim 1 ,
wherein the electrical wire holder includes:
a tube-shaped main body that is capable of enclosing the electrical wire; and
an elastically bendable part that constitutes a portion of the tube-shaped main body and is capable of being elastically displaceable in a radial direction, and

the locking part is formed on the elastically bendable part.

5. The wire harness according to claim 1 ,
wherein the locking part is capable of being locked to an inner circumferential surface of the corrugated tube, and
a base end portion of the rubber boot is fitted onto an area of the corrugated tube, the area corresponding to the locking part.

6. An electrical wire protector comprising:
a corrugated tube capable of enclosing an electrical wire having a front end portion to which a terminal fitting is fixed;
a rubber boot that is attached to a front end portion of the corrugated tube and is capable of enclosing the electrical wire; and
an electrical wire holder that is provided with: a holding part capable of holding the electrical wire, and a locking part;
wherein the locking part has a groove shape or a rib shape and locks to the circumferential surface of the corrugated tube.

7. The electrical wire protector according to claim 6 ,
wherein the electrical wire holder includes:
a tube-shaped main body that is capable of enclosing the electrical wire; and
an elastically bendable part that constitutes a portion of the tube-shaped main body and is capable of being elastically displaceable in a radial direction, and
the locking part is formed on the elastically bendable part.

8. The electrical wire protector according to claim 6 ,
wherein the locking part is capable of being locked to an inner circumferential surface of the corrugated tube, and
a base end portion of the rubber boot is fitted onto an area of the corrugated tube, the area corresponding to the locking part.

9. An electrical wire holder that constitutes an electrical wire protector together with: a corrugated tube capable of enclosing an electrical wire having a front end portion to which a terminal fitting is fixed; and a rubber boot that is attached to a front end portion of the corrugated tube and is capable of enclosing the electrical wire, the electrical wire holder comprising:
a holding part capable of holding the electrical wire; and a locking part capable of being locked to a circumferential surface of the corrugated tube, wherein the locking part has a groove shape or a rib shape and locks to the circumferential surface of the corrugated tube.

10. The electrical wire holder according to claim 9 , further comprising:
a tube-shaped main body that is capable of enclosing the electrical wire; and
an elastically bendable part that constitutes a portion of the tube-shaped main body and is capable of being elastically displaceable in a radial direction,
wherein the locking part is formed on the elastically bendable part.
