Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a wire harness removing part and a wire harness which can improve workability when removing a wire harness arranged in a vehicle from a vehicle body. .

[0002]

2. Description of the Related Art Amid growing 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 by electronically controlled vehicles in recent years is enormous, and the present situation cannot be ignored.

Conventionally, when removing a wire harness from a waste vehicle body, a J-shaped hook is hooked on the wire harness and pulled up by a lifting device such as a crane to be removed. 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 pulling up often fails. Further, it is necessary to select an appropriate hooking point so as not to skid sideways, resulting in poor workability.

On the other hand, in order to improve the workability of removing the wire harness when dismantling a discarded vehicle, it is referred to as a so-called twisted rope (having a substantially circular cross section) or a flat rope (flat shape). It has been proposed to use a wire harness detaching part in which the strip is formed into a loop. This wire harness removing part has one turn around the wire harness and a part of the wire harness is inserted into the loop so that an eye for hooking a hook of a lifting device such as a crane when dismantling a discarded vehicle is formed. Used by being attached to a wire harness. This way,
Since skidding is prevented and it is not necessary to select a hooking point, workability can be improved.

However, in the method of attaching the wire harness removing parts as described above, since the load applied by the hook of the pulling device at the time of removing the wire harness is tolerated, the twisted rope or the flat rope forming the wire harness removing parts is It was necessary to have sufficient load bearing capacity, and the rope diameter and rope width were inevitably increased or decreased. If the rope diameter or rope width becomes too thick or too large, it may interfere with the assembly of the wire harness with such wire harness removal parts attached to the vehicle.
Problems such as hindering space saving will occur. Further, the use of a wire harness detaching part having a large or large rope diameter or rope width causes an increase in cost.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to preferred examples. 1A and 1B are explanatory views of a method for attaching a wire harness removing part according to an embodiment of the present invention, in which FIG. 1A is a plan view showing a state before attachment, and FIG. 1B is a sectional view showing a state before attachment. , (C) are cross-sectional views showing a state after attachment. Further, FIG. 2 is a perspective view showing a state after attachment. In the present embodiment, a loop-shaped wire harness detaching component made of a belt-shaped body called a so-called flat rope is used. In FIG. 1, reference numeral 1 is a wire harness removing part,
Reference numeral 1A is a hook hooking portion, 1B and 1C are winding portions, 2 is a wire harness, 2A and 2B are bifurcated bundles of wire harness constituting electric wires, 3 is a slit, and 4 is an eye.

In this embodiment, first, FIGS. 1 (a) and 1 (b) are used.
As shown in FIG. 3, in the portion of the wire harness 2 to which the wire harness removing component 1 is attached, the bundle of electric wires forming the wire harness 2 is divided into two forks to form the slit 3. Next, the wire harness removing component 1 is wound around the wire harness 2 (2A, 2B) once, and the opposing portions 1a, 1b are inserted into the slits 3,
As shown in (b) and (c), the wire harness 2 is tightened by pulling it upward from below. As a result, as shown in FIG. 2, a hook hooking portion 1A for hooking a hook of a lifting device such as a crane is formed, and the inside thereof becomes an eye 4 for inserting the hook. Further, winding portions 1B and 1C that wind around the wire harness 2 are formed on both sides of the hook hooking portion 1A. Also, by tightening the wire harness 2, the slit 3 is closed,
The detachment of the wire harness removing component 1 from the wire harness 2 is prevented.

The flat rope constituting the wire harness removing part 1 used in this embodiment has a strength (resistance to withstand when pulled by a hook of a lifting device such as a crane when dismantling a discarded vehicle). An appropriate material can be used as long as it has a load property, but it is preferable to use a resin material such as nylon or polyester in terms of cost. Further, the thickness, width, and loop length of the flat rope used in the wire harness detaching component 13 may be appropriately set depending on the material, the type and size of the wire harness 2 to be attached.

According to the method of attaching the wire harness removing component 1 as described above, not only is the workability of removing the wire harness and the disassembling cost extremely excellent, but also the following advantages are provided. is there. That is, since the hook hooking portion 1A formed by the wire harness removing part 1 has a double structure as shown in FIG. 1 (c), it has been conventionally used as a flat rope constituting the wire harness removing part 1. It is possible to use one having a lower withstand load (about half) and a smaller cross-sectional area, which does not hinder the assembly when the wire harness 2 to which the wire harness detaching component 1 is attached is assembled in a vehicle, thus saving space. In addition to cost reduction, there are cost advantages.

The present invention has been described above based on an embodiment, but the present invention is not limited to the above embodiment, and various modifications and changes can be made. For example, in the above description, the flat part made of a flat rope is used as the wire harness removing part, but a substantially circular cross-section made of a twisted rope, a rope other than the twisted rope, and the like can be used. Further, in order to more effectively prevent the wire harness removing part from coming off from the wire harness, the wire harness removing part may be fixed with an adhesive tape or the like. In addition, a binding tape may be wrapped around both sides of the wire harness part to which the wire harness removing part is attached, and in this case, lateral displacement of the wire harness removing part is effectively prevented when the wire harness is removed.

Further, according to the present invention, there is provided a wire harness to which the wire harness detaching component is attached by the above method.

[0014]

According to the present invention, since the above-described method and configuration are adopted, it is easy to attach to a wire harness, sufficient load resistance can be obtained, space can be saved, and a cost merit can be produced. You can
