Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness to be routed to a vehicle and a mounting structure of the wire harness, and more particularly to a structure in which the wire harness can be easily removed from the vehicle when the vehicle is disassembled.

[0002]

2. Description of the Related Art In recent years, development of automobile recycling has been promoted from various points, and there has been a demand for designing automobiles in consideration of recycling. For example, when considering the recycling of a steel body of an automobile, if copper is contained, separation from iron is not easy, and therefore, there is a problem that the purity of the recycled iron is reduced. Therefore, it is important to remove the wire harness, which is a lump of copper, from the automobile when dismantling it.

Normally, as shown in FIG. 5, a wire harness W / H is fixed to a body 2 using a board type clamp 1 (or a band type clamp). The substrate type clamp 1 has a shaft portion 1c provided with a locking blade portion 1b protruding from a substrate portion 1a fixed to a wire harness W / H by a tape T.

A locking hole 2a is formed in advance on the body 2 side of the automobile. As shown in FIG. 6 (A), a clamp 1 fixed to a wire harness W / H is fixed to a locking blade portion 1 thereof.
6b is bent and pushed into the locking hole 2a and inserted.
As shown in (B), the locking blade 2b is locked to the locking hole 2a by the locking blade 1b.

[0005]

When the wire harness W / H is removed from the body 2 during disassembly of the vehicle, it is necessary to pull out the locking blade 1b of the clamp 1 from the locking hole 2a. Once inserted into the locking hole 2a, it cannot be easily extracted and requires a jig. In addition, since the jig is located behind the wire harness W / H, the clamp can be easily extracted using the jig. I can't work. In addition, since a large number of clamps are attached to the body at a required interval and locked to the body even in a single wire harness, it is very troublesome and time-consuming to remove these many clamps one by one from the body. There's a problem.

In order to solve the above-mentioned problems, clamps which can be removed from the body locking holes have been proposed. However, all of them have a complicated structure, and furthermore, it is necessary to remove the clamps one by one. , There was a problem of poor work efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has an object to fix a wire harness to a body without using a clamp, so that the wire harness can be more easily and efficiently removed than a body when dismantling an automobile. Is an issue.

[0008]

In order to solve the above-mentioned problems, the present invention is directed to a first aspect of the present invention, wherein an adhesive material is provided on one surface of an outer periphery of a wire group constituting a wire harness or an outer periphery of a tape wound around the wire group. A magic tape having a male or female flocked locking piece protruding on the other surface and being wound on the other surface, the adhesive material side is roughly wound around the electric wire group or the outer peripheral surface of the tape. The male and female flocked locking pieces are locked to the magic tape which is fixed and is fixed to the fixing member on the vehicle body side in advance, and the male or female flocked locking piece is protruded. Thus, there is provided a wire harness in which the wire harness is attached to a fixing member.

When the electric wires are roughly wound by the above-mentioned magic tape, the electric wires are bound by the magic tape. When the electric wires are bound with a normal adhesive tape, the magic tape is roughly wound around the surface of the adhesive tape.

As described above, when the wire harness in which the magic tape is roughly wound is attached to a fixing member made of a body or a large-sized resin molded product on which the magic tape is previously attached, the wire harness in the area where the magic tape is attached can be one-touch. In addition, when the vehicle is dismantled, the wire harness can be released by one-touch only by pulling the wire harness more strongly than the fixing member.

According to a second aspect of the present invention, the instrument panel harness is roughly wound with a magic tape provided with either male or female flocked locking piece, and the instrument is coated with an adhesive applied to the back surface thereof. While the panel / harness is fixed, a wiring groove is recessed in the instrument panel to be molded with resin, and along the bottom surface of the wiring groove, a magic tape roughly wound and fixed to the instrument panel / harness is engaged. A magic tape provided with either the male or female flocked locking piece to be stopped is fixed with an adhesive applied to the back surface thereof, and the instrument panel
Provided is a wire harness mounting structure in which a harness is inserted to lock and fix the male and female Velcro.

As described above, the harness wiring groove is formed in advance on the instrument panel to be molded with resin, and the magic tape is fixed along the bottom surface of the wiring groove, so that the inside of the wiring groove is formed. By simply pushing in the instrument panel / harness, the male and female flocked locking pieces can be fitted and fixed. In addition, since the instrument panel and harness are inserted into the recessed routing grooves to protect them and prevent the instrument panel and harness from interfering with other components, the wire can be sufficiently connected even when using Velcro. The harness can be fixed to the panel.

When the wire harness is detached from the panel for repair or replacement, if the wire harness is pulled strongly, the wire harness is detached from the magic tape on the routing groove side, and is taken out from the routing groove and easily repaired and replaced. Can be. Further, when the vehicle is dismantled, the wire harness can be easily removed from the panel similarly.

The location where the wiring harness is routed is
Not limited to instrument panels made of resin,
The same applies to the case where the wiring groove is formed in the body of the automobile. Alternatively, the present invention can be suitably applied to a case where a resin guide member having a routing groove formed therein is provided, and the guide member is fixed to a required body body.
