Abstract

PROBLEM TO BE SOLVED: To improve workability in dismounting a wire harness from a vehicle, when the vehicle is dismantled. SOLUTION: For this wire harness 10, an eye 14 is formed by exposing a part of a wire 12 within a wire bundle W bundled with tape 2 and by turning it once. When a vehicle is dismantled, the hook of a crane truck is locked to the eye 14 of the wire harness 10 and is pulled up, so that the wire harness 10 is dismounted from the vehicle body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness capable of improving workability when removing a wire harness routed from a vehicle from a vehicle body.

[0002]

2. Description of the Related Art Amid increasing awareness of environmental issues, interest in the effective use of resources is increasing. Such problems are no exception for discarded vehicles. In particular, the amount of wire harnesses used in recent electronically controlled vehicles is enormous, and at present it cannot be ignored.

[0003] Under such circumstances, wire harnesses are still being recycled at present, but there is a problem that it is not easy to remove the wire harness from the vehicle. This will be described in detail below with reference to FIGS.

[0004] A wire harness 1 is a bundle W of a plurality of electric wires.
Are bundled and a binding tape 2 is wound therearound, and a connection with an electric system in the vehicle is made through a connector 3 connected to an end of a bundle W of electric wires. Generally, the wire harness 1 is provided with a locking member or a clamp 4 firmly attached to the wire harness 1 by a tape 5 in the middle of the wire harness 1.
It is customary to carry out the attachment. The clamp 4 has an anchor-shaped engaging portion 4a, and is fixed to the vehicle body B by fitting the engaging portion 4a into a through hole 6 of the vehicle body B as shown in FIG. ing.

When the wire harness 1 wired to the vehicle using the clamp 4 is detached from the vehicle, the clamp 4 is pulled out from the through hole 6 of the vehicle body B by applying a tensile force to the clamp 4 to remove the clamp 4. Forced work is required to remove the through hole 6. From this, the dismantling of the vehicle,
When removing the wire harness 1 from the vehicle body B, a crane truck is often used.

However, since the clamper of the crane truck, that is, the gripping portion is too large as compared with the outer diameter of the wire harness 1, gripping the wire harness 1 using the clamper of the crane truck requires a delicate operation. However, there was a problem that the workability was poor.

There is another problem that when the wire harness 1 is separated from the vehicle body B after the wire harness 1 is gripped by the clamper, the wire harness 1 is easily detached from the clamper of the crane truck. Of course, when the wire harness 1 is detached from the clamper, the wire harness 1 must be gripped again by the clamper. For these reasons, removing the wire harness 1 requires time and effort.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire harness which can improve the workability when detaching the vehicle from the vehicle when the vehicle is disassembled.

[0009]

According to the present invention, in order to solve the above-mentioned problems, in a wire harness formed by binding a bundle of electric wires with a tape, a part of the bundle of the electric wires in the middle of the bundle of the electric wires is provided. A wire harness is provided, wherein an eye for hooking a hook of a crane truck at the time of disassembly of a vehicle is formed by making one rotation while the portion is exposed to the outside.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to preferred embodiments. FIG. 3 shows a wire harness 10 according to the present invention. In FIG. 3, the same members as those described in FIGS. 1 and 2 are denoted by the same reference numerals. The wire harness 10 exposes a part of the electric wire 12 of the bundle of electric wires W bound by the tape 2 to the outside, and rotates the wire 12 once to make an eye 14.
Are formed.

That is, as schematically shown in FIG. 4, some of the electric wires 12 included in the electric wire bundle W of the wire harness.
The wire harness 1 has a length dimension longer than that of the other electric wires 16, and is formed by winding an intermediate portion thereof to form the eye 14 and then winding the tape 2 around the bundle W of the electric wires.
0 is made.

The number of the electric wires 12 forming the eye 14 may be one as illustrated in FIG.
Although a plurality of wires may be provided, all of the wire bundle W
Need not be formed. Empirically, it is sufficient to form the eye 14 on at most 70% of the wire bundle W of the wire.

It is preferable to select a position where the eye 14 is formed near the clamp 5 because a pulling force by a crane truck described later can be directly transmitted to the clamp 5. The eyes 14 may be provided at a plurality of locations on the wire harness 10. In this case, two or more eyes 14 may be formed on the same electric wire, and the eyes 14 may be formed at different positions of different electric wires, respectively, so that the wire harness 10 may have a plurality of separated eyes 14. May be provided.

When dismantling the vehicle, the arm 2 of the crane truck is used.
And a hook 26 attached to the tip of the wire rope 24 (FIG. 5).
Is hooked on the eye 14 of the wire harness 10, and then the clamper 22 of the crane 20 is raised,
Pull up the wire harness 10. As a result, the clamp 5 of the wire harness 10 is forced out of the through hole 7 of the vehicle body B, and the wire harness 10 can be removed from the vehicle body B.

The diameter of the eye 14 may be set in accordance with the size of the hook 26 to be used. Empirically, the eye 14 may have a diameter of 15 mm or more.

[0016]

According to the present invention, since the above-mentioned structure is adopted, a hook attached to a winch via a wire rope, for example, is securely and easily hooked to an eye in a vehicle disassembling operation, so that a wire harness is provided. Since it can be grasped and pulled out, it is possible to perform sorting and collecting with good workability.
