[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp mounting structure for a bundle of wires covered with a protective sheet such as a vinyl tube or a vinyl sheet.

[0002]

2. Description of the Related Art An electric wire of this kind is clamped to a wiring portion such as a vehicle body panel. And this clamp is pre-attached to the specified part of the wire,
The attachment means is fixed by winding a clamp around the outer periphery of the protective sheet covering the electric wire with vinyl tape.

[0003]

However, if the adhesive strength of the vinyl tape is reduced due to the temperature effect of the place where the clamp is attached, the clamp will come off from the electric wire side and will not be able to fulfill its function. Also, when attaching the clamp to the electric wire side, the vinyl tape must be wound many times, and the operation is complicated.

[0004] The technical problem of the present invention is to make sure that the clamp is attached to the electric wire and to simplify the attaching operation.

[0005]

In order to solve the above problems, the clamp mounting structure of the present invention is configured as follows. That is, a clamp mounting structure for a bundle of wires covered with a protection sheet, wherein the protection sheet includes both ends of the clamp with the protection sheet and the wires.
Mounting holes that can be inserted individually between the clamps, while locking feet are formed in the approximate center of the clamp
Together are, the same and the locking leg at both ends of the clamp
A claw projecting in the direction is formed.

[0006]

According to this structure, both ends of the clamp are inserted between the protective sheet and the electric wire through the mounting holes.
At the same time, make both nails protrude to the surface side of the protection sheet
You. This direct clamp the protective sheet,
In addition, it is securely attached, and the work is simplified.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Embodiment 1 FIG. 1 shows a perspective view of a part of an electric wire 10 and a clamp 20. A plurality of the electric wires 10 are bundled in a bundle, and the outer periphery thereof is covered with a protective sheet 12 such as a vinyl tube or a vinyl sheet. This protective sheet 12
A pair of left and right mounting holes 14 are formed by cutting the outer periphery into a partial slit shape. Further, in the protective sheet 12, a hole 16 having the same shape as the mounting holes 14 is formed at a position adjacent to the mounting holes 14.

On the other hand, the clamp 20 is an integrally molded product made of a synthetic resin material, and a locking leg 24 is formed integrally at a substantially central portion thereof. Claws 22 projecting in the same direction as the locking legs 24 are integrally formed at both ends of the clamp 20. In addition, a return portion 22a is formed at the tip of each of the claws 22. FIG. 2 is a sectional view showing a state where the clamp 20 is attached to the electric wire 10. As is clear from this drawing, both ends of the clamp 20 can be individually inserted into the mounting holes 14 of the protective sheet 12, whereby both ends of the clamp 20 are moved from the front side of the protective sheet 12 to the back side. It is designed to be inserted on the side. When both ends of the clamp 20 are inserted into the mounting holes 14,
Project to the front side through the hole 16 of the protective sheet 12. As shown in FIG. 2, the locking leg 24 of the clamp 20 can be inserted into a hole 32 formed in a body panel 30 of a vehicle, which is a wiring location of the electric wire 10.

The mounting holes 14 and the through holes 16 of the protective sheet 12 are previously formed at designated positions of the electric wire 10 where the clamps 20 need to be mounted.
Is attached to each of these locations. The procedure for mounting the clamp 20 will now be described.
The two end portions of the clamp sheet 20 are sequentially inserted from the respective mounting holes 14 to the rear surface side of the protective sheet 12, and both claws 22 of the clamp 20 are projected from the hole 16 to the front surface side of the protective sheet 12 (see FIG. 2). At this time, the return portions 22a of the claws 22 are caught by the edges of the respective holes 16 and cannot be easily removed. Thereby, the clamp 20 is directly and securely attached to the protective sheet 12.

After the clamps 20 are respectively attached to the designated portions of the electric wires 10 as described above, the locking legs 24 of each clamp 20 are sequentially inserted into the holes 32 of the body panel 30 so that the electric wires 10 are wired. In a state where the locking legs 24 are locked on the body panel 30 side, as shown in FIG.
Is elastically bent, and the resilience prevents rattling (vibration) of the clamp 20 with respect to the body panel 30 and generation of abnormal noise therewith, and stabilizes the mounting state of the clamp 20.

Embodiment 2 FIG. 4 is a perspective view showing a different embodiment for attaching the clamp 20 to the electric wire 10, and FIG. 5 is a sectional view showing the state where the clamp 20 is attached. In this embodiment, the electric wire 1 is used.
0, the entire length of the protective sheet 12 covering the
The protective sheet 12 is provided with mounting holes 14 near both ends thereof.
Only, and the hole 16 of the first embodiment is omitted. In order to mount the clamp 20 on the protective sheet 12, as shown in FIG. 5, both ends of the clamp 20 are inserted from the respective mounting holes 14 to the back side of the protective sheet 12, and both claws 22 of the clamp 20 are From both ends to the surface side. As a result, the return portions 22a of the claws 22 are caught by both ends of the protective sheet 12 and cannot be easily removed, and the clamp 20 is directly and securely attached to the protective sheet 12 as in the first embodiment.

Embodiment 3 FIGS. 6 and 7 show a clamp 20 for a body panel 30.
FIG. 4 is a cross-sectional view showing different modes for mounting the hologram. In the present embodiment, a concave portion 34 (FIG. 6) or a hole 36 in which both claws 22 of

The rotation about the fulcrum 4 is restricted, and the mounting direction of the clamp 20 (the wiring direction of the electric wire 10) can be set as desired.

[0013]

[Effects of the Invention] In the present invention, the clamp can be directly and securely attached to the protective sheet covering the electric wire, so that the clamp is prevented from coming off after the wiring of the electric wire, and the work of attaching the clamp is easy. Becomes
