Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clamp mounting structure for a bundle of electric wires covered with a protective sheet such as a vinyl tube or a vinyl sheet.

[0002]

[Prior art]

 This type of electric wire is clamped at a wiring location such as a vehicle body panel. The clamp is pre-attached to the designated place on the electric wire, and the attachment means is that the clamp is wrapped and fixed with vinyl tape around the outer periphery of the protective sheet covering the electric wire.

[0003]

[Problems to be solved by the device]

 However, if the adhesive strength of the vinyl tape decreases due to the effect of temperature on the place where the clamp is attached, this clamp will come off the wire side and it will no longer be able to fulfill its role. Also, the vinyl tape had to be wound many times when the clamp was attached to the wire side, which was a complicated task.

The technical problem of the present invention is to secure the mounting state of the clamp on the electric wire and to simplify the mounting work.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the clamp mounting structure of the present invention is constructed as follows. That is, it is a structure for mounting a clamp on a bundled electric wire covered with a protective sheet, and the protective sheet has mounting holes into which both ends of the clamp can be individually inserted from the front side to the back side of the protective sheet. On the other hand, at both ends of the clamp, claws that can project from the back surface side to the front surface side of the protective sheet are formed at positions other than the mounting holes.

[0006]

[Action]

 According to this configuration, both ends of the clamp are inserted into the back surface side of the protective sheet through the mounting holes, that is, between the electric wire and the protective sheet, so that the clamp is attached to the electric wire side. Moreover, in this state, the claws formed at both ends of the clamp project to the surface side of the protective sheet at a position other than the mounting holes, and the clamp is directly locked to the protective sheet. Therefore, the clamp can be mounted securely, and the mounting work becomes easy.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Example 1 FIG. 1 is a perspective view showing a part of an electric wire 10 and a clamp 20. A plurality of the electric wires 10 are bundled into a bundle, and the outer circumference thereof is covered with a protective sheet 12 such as a vinyl tube or a vinyl sheet. The protective sheet 12 is formed with a pair of left and right mounting holes 14 by cutting the outer periphery thereof into a partial slit shape. Further, in the protective sheet 12, at positions adjacent to both the mounting holes 14, punch holes 16 having the same shape as the mounting holes 14 are formed.

On the other hand, the clamp 20 is an integrally molded product made of a synthetic resin material, and a locking leg 24 is integrally formed at a substantially central portion thereof. Further, claws 22 projecting in the same direction as the locking legs 24 are integrally formed at both ends of the clamp 20, respectively. Moreover, a return portion 22a is formed at the tip of each of the claws 22. FIG. 2 shows a sectional view of the electric wire 10 to which the clamp 20 is attached. 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, so that both ends of the clamp 20 are located on the front side of the protective sheet 12. It is designed to be inserted from the back side. Then, when both ends of the clamp 20 are inserted into the respective mounting holes 14, the above-mentioned both claws 22 project to the front surface side through the above-mentioned holes 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 the body panel 30 of the vehicle, which is a wiring portion of the electric wire 10.

By the way, the mounting hole 14 and the removal hole 16 of the protective sheet 12 are formed in advance at the designated positions of the electric wire 10 where the clamp 20 needs to be mounted, and the clamp 20 is mounted at each of these positions. . Therefore, the procedure for attaching the clamp 20 will be described. First, both ends of the clamp 20 are sequentially inserted from the respective attachment holes 14 to the back surface side of the protective sheet 12, and the claws 22 of the clamp 20 are inserted into the extraction hole 16 described above. From above to the surface side of the protective sheet 12 (see FIG. 2). At this time, the return portions 22a of the both claws 22 are caught by the edges of the respective holes 16 and cannot be easily removed. As a result, the clamp 20 is directly and securely attached to the protective sheet 12.

After the clamps 20 are attached to the designated positions of the electric wires 10 in this way, the locking legs 24 of the clamps 20 are sequentially inserted into the holes 32 of the body panel 30 to wire the electric wires 10. When the locking leg 24 is locked to the body panel 30, the both claws 22 hit the body panel 30 and the clamp 20 is elastically bent as shown in FIG. The rattling (vibration) of the clamp 20 with respect to the body panel 30 and the accompanying noise generation are prevented, and the mounted state of the clamp 20 is stabilized.

Embodiment 2 FIG. 4 is a perspective view showing a different mode for attaching the clamp 20 to the electric wire 10, and FIG. 5 is a sectional view showing the state in which the clamp 20 is attached. In this embodiment, the total length of the protective sheet 12 covering the electric wire 10 is as short as the length of the clamp 20. In the protective sheet 12, only the mounting holes 14 are provided at positions near both ends thereof. Is formed, and the hole 16 in the first embodiment is omitted. Therefore, 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 into the back side of the protective sheet 12 through the respective mounting holes 14, and the both claws 22 of the clamp 20 are protected. The sheet 12 is projected from both ends to the front side. As a result, the return portions 22a of both the claws 22 are caught on both edges of the protective sheet 12 and cannot be easily removed, and the clamp 20 is directly and surely attached to the protective sheet 12 as in the first embodiment. .

Embodiment 3 FIGS. 6 and 7 are cross-sectional views showing different modes for attaching the clamp 20 to the body panel 30, respectively. In this embodiment, the body panel 30 is provided with a recess 34 (FIG. 6) or a hole 36 (FIG. 7) into which both the claws 22 of the clamp 20 are inserted. As a result, the clamp 20 mounted on the body panel 30 is restricted from rotating about the locking leg 24 as a fulcrum, and the mounting direction of the clamp 20 (wiring direction of the electric wire 10) can be set as desired.

[0013]

[Effect of device]

 According to the present invention, since the clamp is directly and surely attached to the protective sheet covering the electric wire, the clamp is prevented from coming off after wiring the electric wire, and the work for attaching the clamp is facilitated.
