Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a wire harness for a vehicle to a vehicle body panel using a clamp, and more particularly to a structure for easily removing a wire harness from a vehicle body panel when disassembling a vehicle. is there.

[0002]

2. Description of the Related Art Conventionally, in order to route a wire harness along a vehicle body panel, for example, a board-type clamp 1 is used.
The both ends of the substrate 1A are wound around the wire harness W / H with an adhesive tape T, and the mounting blades 1a are inserted into the mounting holes 2a of the vehicle body panel 2 when the vehicle is mounted on the vehicle. It is fixed to panel 2 (FIG. 5).

However, in the mounting structure of the wire harness using the board type clamp 1, as described above, the board 1A is wound around the wire harness W / H by the adhesive tape T, and the temperature and the humidity are controlled. When the adhesive force of the adhesive tape T decreases due to the change, there is a possibility that the adhesive tape T may be separated from the wire harness W / H from the clamp 1.

For this reason, while the claw portions 12 are projected from both ends of the substrate 1A, the protection sheet 13 is wound around the wire harness W / H, and the slits 13A for inserting the claw portions 12 at both ends of the substrate 1A into the protection sheet 13 are provided. (FIG. 6A) A slit 13B for drawing out the inserted claw portion 12 is formed.
(FIG. 6 (B)) Alternatively, a slit 13A is formed in the protective sheet 13 for inserting the claw portions 12 at both ends of the substrate 11, and the claw portions 12 are formed in gaps S between the wire harness W / H on both sides of the sheet.
For example, there is a structure in which the wire harness W / H is not easily detached from the clamp 11 by pulling it out (FIGS. 7A and 7B) (Japanese Utility Model Laid-Open No. 7-23885).

[0005] Note that there is a band-type clamp that attaches to a wire harness with a tie band.
When the band-type clamp is used, a tie band connected to a part of the box-shaped base having the locking wings protruded is wound around a wire harness, and the tie band is fixed to a locking hole inside the box-shaped base. Since the wire harness is held by the band for locking and fixing, and the band does not loosen over time, there is no worry that the wire harness is detached from the clamp after the attachment.

[0006]

In recent years, there has been a demand for effective use of resources, and it has been demanded that vehicle body panels can be recycled. In that case, if copper is contained, it is difficult to separate from iron, which is the main component of the body panel, and the purity of iron decreases, so when dismantling the automobile, the wire harness, which is a lump of copper, is separated from the body panel. It is important.

However, in the clamp and wire harness mounting structure shown in FIGS. 6 and 7, when the clamp 11 and the wire harness W / H are to be separated manually, it is necessary to cut the protective sheet 13 with a blade. In addition to the danger, there is a problem that workability is poor. The same applies to the case where a band-type clamp is used, and the band must be cut with a blade, which causes the same problem.

The present invention has been made in view of the above circumstances, and when the vehicle is mounted on a vehicle (when the wire harness is attached to a vehicle body panel), the wire harness does not come off from the clamp, and the vehicle is dismantled. Sometimes,
It is an object of the present invention to enable a human to easily and safely separate a wire harness from a clamp without using a special tool.

[0009]

In order to solve the above problems, according to the present invention, a clamp is fixed to a wire harness, and the clamp is locked in a mounting hole of a vehicle body panel to connect the wire harness to the vehicle body. A structure for attaching a wire harness to a vehicle body panel to be attached along a panel, wherein one of two substantially parallel slits formed in a synthetic resin sheet and the other are provided on both ends of a clamp for preventing the clamp from coming off from the slits. One end side and the other end side of the substrate having the wide portion are sequentially inserted to hold the clamp, and the synthetic resin sheet holding the clamp is wound around a wire harness and exteriorized, while the locking portion of the clamp is mounted on the vehicle body. The wire harness is attached to the body panel by locking it to the mounting hole of the panel. When the wire harness is removed from the body panel, the locking part of the clamp is almost The wire harness is bent so that the one end side and the other end side of the clamp substrate are sequentially extracted from the two slits of the synthetic resin sheet which is largely opened by the bending of the wire harness. The present invention provides a structure for attaching a wire harness to a vehicle body panel, which is separated from the vehicle body panel.

Specifically, in the clamp substrate, the width (W1) of the wide portion at both ends is made larger than the length (L1) of the slit, and the width (W2) of the intermediate portion between the wide portions at both ends is increased. It is shorter than the length (L1) of the slit and the length (L
2) is made longer than the separation distance (L3) between the two slits (claim 2), so that the wide portions at both ends of the substrate are inclined with respect to the slits, so that they cannot be inserted into the slits unless they are inserted one by one. .

Further, the synthetic resin sheet is wound around the wire harness by adhering a double-sided tape to one end of the outer surface of the synthetic resin sheet and bonding an overlapping portion of the sheet with the double-sided tape, or Is applied to one end of the sheet, and the overlapping portions of the sheets are bonded with the adhesive.

In the above-described structure for mounting the wire harness to the vehicle body panel according to the present invention, the clamps locked in the mounting holes of the vehicle body panel are in a state where both ends of the substrate are inserted into two slits of a sheet provided on the wire harness. Therefore, the wire harness is not detached from the clamp when the wire harness is attached to the vehicle body panel. Then, when removing the wire harness from the vehicle body panel, such as when disassembling the vehicle body,
When holding the wire harness by hand and bending the wire harness so that the locking portion of the clamp is approximately at the top, the synthetic resin sheet expands and two slits are greatly opened, and the wire harness is tilted up, down, left and right When the clamp is slightly moved, both ends of the substrate of the clamp easily come out of the slits, and the clamp and the wire harness are separated.

In order to more reliably position the synthetic resin sheet on the wire harness when mounted on an automobile, the entire circumference of both sides of the synthetic resin sheet wound around the wire harness is fixed to the outer periphery of the wire harness with an adhesive tape. (Claim 3).

0a and 20b are shorter than the length (L1), and the length of the intermediate portion (L2) is longer than the separation distance (L3) between the two slits 20a and 20b.

The clamp is attached to the wire harness as follows. First, one wide portion 3 of the clamp 30
1a is inserted into one of the slits 20a of the sheet 20 at an angle (FIG. 2A), and the other wide portion 31b is inserted at an angle into the other slit 20b to hold the clamp 30 on the sheet 20. (FIG. 2 (B)). Here, the clamp 30 has the above-described dimensional relationship with the sheet 20, and the clamp 30 does not separate unless the sheet 20 is significantly deformed.

Next, the sheet 20 is wound around a predetermined portion of the wire harness W / H, and the overlapping portion of the sheet is adhered with a double-sided tape 21 adhered to one end of the outer surface of the sheet 20 (FIG. 3A). In order to further ensure the positioning of the wire harness W / H to the wire harness W / H,
The entire periphery of both sides of the sheet 20 wound around H is adhered to the periphery of the wire harness with an adhesive tape T (FIG. 3B).
