Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness having excellent recyclability, which can improve workability when removing the wire harness from the vehicle body when dismantling a discarded vehicle.

[0002]

2. Description of the Related Art With increasing awareness of environmental problems, interest in 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 it is the current situation that this cannot be ignored.

When the wire harness is removed from the vehicle body when dismantling a discarded vehicle, conventionally, a J-shaped hook is hooked on the wire harness and pulled up by a lifting device such as a crane for removal. However, in such a method, when the wire harness is removed, the wire harness often slips at the portion where the J-shaped hook is hooked, and the pulling up often fails. Further, it is necessary to select an appropriate hooking point so as not to skid sideways, resulting in poor workability.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, prevents side slippage when the wire harness is removed from a discarded vehicle, and sets the wire harness hooking point at an arbitrary position. It is an object of the present invention to provide a wire harness which is excellent in recyclability and which can improve workability.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to preferred examples. 1 to 4 are explanatory views of a wire harness according to an embodiment of the present invention. The wire harness of the present embodiment is formed by combining a plurality of sets of temporary binding harnesses in which terminals crimped to each end of a plurality of electric wires are connected to a connector and sub-assembled, and finally bound together, and an exterior material is attached. It has been done. In addition, the wire harness of the present invention incorporates, for at least one or more temporary binding harnesses, a pulling-up component in which a hooking portion for hooking a hook of a lifting device is formed at the time of disassembling a discarded vehicle, and the hooking portion is externally provided. It was exposed.

Here, a wire harness according to the present embodiment will be described in an extremely simplified schematic example. FIG. 1A schematically shows the first temporary binding harness 1. Terminals (not shown; the same applies below) are crimped to both ends of the electric wire 11 and connected to the connectors A and B, respectively. Terminals are also crimped to both ends of the electric wire 12, and crimped to the connectors A and C, respectively. The electric wire 11 and the electric wire 12 are temporarily bound by a temporary binding member (not shown) such as a tape or a binding band, and sub-assembled. FIG. 1 (b) schematically shows the second temporary binding harness 2, in which terminals are crimped to both ends of the electric wire 13,
They are connected to connectors D and E, respectively. Also electric wire 1
Terminals are crimped to both ends of 4, and connectors D and F respectively
Is crimped to. And the electric wire 13 and the electric wire 14 are shown in FIG.
As in (a), they are temporarily bound and sub-assembled. What is shown as 3 on the left side of FIG. 1 (a) is a pulling component made of a loop-shaped strip, and is temporarily fixed to the harness branching portion 5 as shown in FIG. First temporary binding harness 1 and second temporary binding harness 2
Are combined as shown in FIG. Then, as shown in FIG. 4, the hooking portion (eye) of the pulling-up component 3
The wire harness W of the present embodiment is obtained by wrapping the binding tape 6 so that the wire 4 is exposed to the outside and binding the binding tape 6 to the main binding.
Has become.

The wire harness W having the above structure is used for pulling up the hook F of a lifting device such as a crane when hooked on the hooking portion 4 of the lifting component 3 as shown in FIG. The binding tape 6 is attached to the component 3, and skid is effectively prevented due to interference with the second temporary binding harness 2 other than the first temporary binding harness 1, friction, etc., and the wire harness W is stably and easily attached. You will be able to remove it. Further, since the position of the hooking portion 4 of the hook F is predetermined, it is not necessary to select the hooking point. Therefore, workability is improved and dismantling cost can be reduced.

Although a wire harness having an extremely simple structure has been described above, according to the present invention, a wire harness in which a larger number of temporary binding harnesses are combined can be provided by a similar method.

Further, as the pulling-up component 3, an appropriate material can be used as long as it has strength enough to withstand the pulling force when hooked by a hook such as a crane when dismantling a scrapped vehicle. In terms of cost, it is preferable to use a resin material such as polypropylene, but it is not limited to this.

The present invention has been described above with reference to one embodiment.
The present invention is not limited to the above embodiment, and various modifications and changes can be made. For example, in the above, as a part for pulling up,
A string-shaped body (including a rope-shaped body) or a member equivalent thereto can be used as long as it has a required tensile strength. It is also possible to use one in which a band-shaped body or a string-shaped body is connected later to form a knot. Further, a loop-shaped cord 7 as shown in FIG. 5 is used, and a part of the loop-shaped cord 7 is passed through the loop of the cord-shaped body 7 so that the small loop 8 is formed with respect to the temporary binding harness. May be formed. Further, a band-shaped body may be used instead of the string-shaped body 7 to form a similar shape. Further, the temporary binding harness in which the pulling-up component is incorporated may be one or plural. Further, in the above, the pulling-up component is incorporated in the branch portion, but it may be a portion other than the branch portion. Furthermore, although the binding tape is wound as the exterior material in the above, a conventionally known appropriate member such as a corrugated tube can be used.

[0012]

EFFECTS OF THE INVENTION According to the present invention, since the above-mentioned structure is adopted, there is no skid when removing the wire harness from the discarded vehicle, and the hooking point of the wire harness can be set at an arbitrary position, thus improving workability. A wire harness that can be improved and has excellent recyclability can be provided.
