Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protective clip for a harness wired inside an automobile.

As a method for placing a harness inside a car, a widely adopted wiring method is, for example, to drill a relatively large insertion hole in the inner panel of the car's engine compartment, and then insert the harness through the hole and lead it to another location. There is. However, regarding such wiring method,
Although the insertion hole is formed by bending the hole edge inward, there have been many cases where the harness comes into contact with the bent hole edge, especially the tip, and breaks due to vibrations during running.

For this reason, conventional measures have been taken such as wrapping a protective tape around the contact outer circumferential surface of the harness, or applying a protective film to the bent edge of the insertion hole as in Japanese Utility Model Publication No. 47-29939. The reality is that this measure alone is not a complete measure to prevent harness breakage.

Therefore, the present invention was devised in view of such breakage of the harness, and consists of a curved part and both straight parts extending to both ends of the curved part, and the curved part is bored in the panel. The insertion hole has a shape that can surround the inside and outside edges and the tip of the bent hole edge, and each straight portion has a shape that can surround the inside and tip of the bent hole edge, and the harness is tied at an appropriate place on the curved portion. The above-mentioned problem is effectively solved by providing a novel protective clip which is provided with a fixing piece having a locking hole for locking a locking leg formed integrally with the means.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment.
is integrally molded from a synthetic resin material, and specifically, as shown in FIG. It consists of both straight parts 3, 3 that extend continuously from both ends of the part 2.

As shown in the figure, the curved portion 2 has a U-shaped cross section consisting of an inner piece 4, an outer piece 5, and a base piece 6, and an insertion hole is formed in the inner space 7 formed by each piece 4, 5, and 6. The bent hole edge can be completely inserted into the bent hole edge, and the inner and outer sides and the tip of the bent hole edge can be surrounded. Further, each straight portion 3 has an L-shaped cross section having only an inner piece 4 and a base piece 6 in each piece of the curved portion 2, and the insertion hole is bent by the continuous inner piece 4 and base piece 6. The configuration is such that it can surround the inside and tip of the hole edge, and a stopper piece 8 is installed horizontally outward at the upper end of each inner piece 4, and one straight line is positioned above the insertion hole during installation. An engagement piece 9 that engages with the outside of the bent hole edge only at the tip of the portion 3 is integrally formed with the base piece 6.

Further, a fixing piece 11 having an engagement hole 10 for engaging a locking leg formed integrally with a binding band, which will be described later, is installed horizontally outward at the upper end of the outer piece 5 of the curved portion 2, and The clip 1 can be fixed to the inner panel by engaging the locking leg of the binding band in the insertion hole 10 of the piece 11 and the insertion hole drilled corresponding to the inner panel.

Therefore, when protecting the harness H from the bent hole edge of the insertion hole using the protective clip 1 having the above structure, first insert the curved portion 2 from the inside of the inner panel P as shown in FIGS. 2A, B, and C. The bent hole edge 12 of the insertion hole 12 that may come into contact with the harness in the space 7 of
a, and completely surround the inner and outer sides of the bent hole edge 12a with the inner and outer pieces 4 and 5, and the base piece 6 at the tip, and the inner piece 4 and the base piece 6 of each straight part 3, 3. When the clip 1 is attached to the insertion hole 12 after obtaining a state in which the inside and the tip of the bent hole edge 12a are continuously surrounded,
Even if the harness H is inserted into the insertion hole 12 as in the conventional case, the bent hole edge 12 of the insertion hole 12
There is no direct contact with a. In addition, in such an installation state, the fixing piece 11 is attached to the inner panel P.
It will be located inside. Moreover, the above-mentioned attachment is in a state where the clip 1 is temporarily fastened.

Next, as shown in FIGS. 3A and 3B, the harness H is bundled into the insertion hole 10 of the fixing piece 11 through the insertion hole 13 separately drilled at the appropriate location of the inner panel P. If the locking leg 14a of the cable tie 14 already attached to the harness H is engaged, the clip 1 will be securely fixed to the inner panel P, and the harness H will also fit into the insertion hole 1 as shown in FIG.
Immediately before being inserted into the inner panel P, the inner panel P is bound with the binding band 14 and held in a fixed position on the inner panel P.

As described above, the protective clip according to the present invention has a curved portion that completely surrounds the bent hole edge of the insertion hole, and both straight portions that extend to both ends of the curved portion and partially surround the bent hole edge. Since the present invention provides a protective clip which is constructed of a curved part and has a fixing piece having an insertion hole in the curved part, the bending hole edge of the insertion hole is surrounded by the curved part and both straight parts, By simply attaching this protective clip to the insertion hole of the panel, the harness is reliably protected from the edge of the bent hole, so there is no fear of it being cut or damaged as in the past. In addition, by locking the locking leg formed integrally with the fastening means such as a cable tie into the locking hole of the fixing piece, not only can the clip itself be securely fixed, but also the locking leg can be secured immediately before insertion. Since it is also possible to hold the harness together, the wiring condition of the harness is also much better than in the past.

Furthermore, this protective clip is not attached to the entire circumference of the insertion hole, but is attached only to the necessary parts of the insertion hole where the harness may come into contact with it, so it is highly economical. It is.
