BACKGROUND OF THE INVENTION
The present invention, when removing the wired by the wire harness to the vehicle from the vehicle body, to a Ruwa ear harness can of improving the workability.
[0002]
[Prior art]
With the growing awareness of environmental issues, there is an increasing interest in the effective use of resources. Such a problem is no exception for discarded vehicles. In particular, the amount of wire harnesses used in recent electronically controlled vehicles is enormous and cannot be ignored.
[0003]
In the case of removing the wire harness from the discarded vehicle body, conventionally, the J-shaped hook is hooked on the wire harness and pulled up by a lifting device such as a crane.
However, in such a method, when removing the wire harness, the wire harness often skids at the portion where the J-shaped hook is hooked, and the pulling up often fails. In addition, it is necessary to select an appropriate hook point so as not to skid, and the efficiency of workability is poor.
[0004]
On the other hand, some proposals for improving the workability of removing the wire harness at the time of dismantling the discarded vehicle have been made. For example, a wire that is formed by connecting ends of a twisted rope (substantially circular in cross section) as a detaching part to form a knot, and forming an eye for hooking a hook of a lifting device when the wire harness is removed Harness removal parts have been proposed. The wire harness removal component will be described with reference to FIG.
[0005]
In FIG. 1, 1 is a wire harness, 2 is a wire harness body, 3 is a wire harness removing member formed by tying both ends of a twisted rope to form a knot 4, 5 is an eye, 6 is a hook hooking portion, 7 is An adhesive tape 8 is a knot stopper.
[0006]
In this conventional example, a loop-shaped wire harness removing part 3 made of a twisted rope is wound once around the wire harness main body 2 and a part thereof is inserted into the loop to lift a crane or the like at the time of dismantling the discarded vehicle. It is wound and fixed so that an eye 5 for hooking the hook of the device is formed (FIG. 1 (a)). Further, the wire harness removing member 3 made of a twisted rope is bent and fixed to the wire harness main body 2 with an adhesive tape 7 in order to prevent detachment and to prevent the installation of other parts. (FIG. 1B, FIG. 1C).
[0007]
With the configuration as described above, the eye 5 for hooking the hook for removing the wire harness 1 can be formed very easily using the wire harness removing part 3 made of a twisted rope, and the wire harness 1 is removed from the vehicle. It becomes possible to improve workability at the time.
[0008]
However, the wire harness removing member 2 made of the above-described twisted rope is very excellent in terms of workability of removing the wire harness, dismantling cost, etc., but has the following problems.
First, the twisted rope forming the wire harness detachment component 3 has a substantially circular cross section and a large diameter, and thus lacks flexibility, and there is a difficulty in workability of attachment to the wire harness body 2. If the twisted rope has a small diameter, there is a problem with load resistance.
Moreover, since the twisted rope has a large diameter, unevenness is generated in a state where the twisted rope is attached to the wire harness body 2 and becomes conspicuous. Moreover, as shown in FIG.1 (c), the magnitude | size of the knot stop part 8 becomes the same as or larger than the diameter of the wire harness main body 2, and it took up a vehicle wiring space, and there also existed a difficulty also in the accommodating property. .
[0009]
[Problems to be solved by the invention]
The present invention has been made to solve such problems of the prior art, and is easy to attach to the wire harness body and improves workability. It is an object of the present invention to provide a wire harness detachment component and a wire harness incorporating the wire harness detachable component, which can save the space and have excellent housing properties and excellent load resistance when the wire harness is removed.

DETAILED DESCRIPTION OF THE INVENTION
The preferred embodiments of the present invention will be described in detail below. FIG. 2 is a view similar to FIG. 1 showing a wire harness removing part according to a reference embodiment of the present invention. In FIG. 2, 11 is a wire harness, 12 is a wire harness main body, 13 is a wire harness removing part, 14 is a knot, 15 is an eye, 16 is a hook hooking portion, 17 is an adhesive tape, and 18 is a knot stopper.
[0012]
This wire harness removing part 13 is a loop formed by tying both ends of a long flat rope to form a knot 14. Then, the wire harness removing part 13 made of a flat rope is wound once around the wire harness body 12, and a part of the wire harness removing part 13 is inserted into the loop, and a hook of a lifting device such as a crane is hooked when the discarded vehicle is disassembled. As shown in FIG. 2 (a), it is wound and fixed so that the eye 15 is formed. Further, the wire harness removing part 13 made of a flat rope is bent and fixed to the wire harness main body 12 with an adhesive tape 17 in order to prevent detachment and to prevent the installation of other parts. (FIG. 2B, FIG. 2C).
[0013]
As the flat rope constituting the wire harness removing component 13, the eye 15 can be formed by winding around the wire harness body 1, and when the hoisting device such as a crane is hooked and pulled up when the discarded vehicle is disassembled, Any material can be used as long as it has strength (load resistance) that can withstand a tensile force, but in terms of cost, use of a resin material such as nylon or polyester is preferable.
[0014]
Further, the thickness and width of the flat rope used for the wire harness removing component 13 vary depending on the material and the size of the wire harness body 12 to be attached, but the thickness is about 1 to 1.5 mm and the width is 10 It is about ˜15 mm and is flat.
