Description

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

As a method of wiring the harness inside the car,
For example, a wiring method is widely used in which a relatively large insertion hole is formed in an inner panel or the like that constitutes the engine room of an automobile, and a harness is inserted through the hole and guided to another location. However, in this wiring method, although the hole edge of the insertion hole is bent inward, the harness may come into contact with the bent hole edge, especially the tip, due to vibrations during driving. , there were many cases of breakage.

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.

The present invention was devised in view of the breakage of the harness, and includes an insertion part that is inserted into the insertion hole bored in the panel, and an upper and lower part installed horizontally on one side wall of the insertion part. The fitting part has a structure that can hold the harness inside itself, and only the side wall on which the upper and lower fixing pieces are installed horizontally has a curved shape corresponding to the curved shape of the insertion hole, and the upper and lower The fixing piece has a structure that can sandwich the inside and outside of the panel by introducing the bent hole edge of the insertion hole between them, and further engages the locking leg formed integrally with the harness binding means to the upper fixing piece. It is an object of the present invention to effectively solve the above-mentioned problem by providing a new protective clip that has an insertion hole for cutting.

Hereinafter, in detail based on an embodiment illustrating the present invention, the harness holding clip 1 according to the present invention is integrally molded from a synthetic resin material, and specifically, the harness holding clip 1 according to the present invention is integrally molded with a synthetic resin material. A fitting part 2 that is fitted into the fitting part 2, an upper fixing piece 3 horizontally installed on the upper part of one side wall of the fitting part 2, and 2 pieces horizontally installed in the lower part of the one side wall on both sides of the upper fixing piece 3. It consists of the lower part fixing pieces 4, 4 of the book.

The fitting part 2 has a planar rectangular shape having a side wall 2a on which the fixing pieces 3 and 4 are installed horizontally, and other side walls 2b, 2c, and 2d, and only the side wall 2a has a curved surface shape corresponding to the curved shape of the insertion hole. At the same time, the side wall 2b facing the curved side wall 2a can be opened and closed via the hinge portion 5, and an engaging claw 6 is provided at the free end of the opening/closing side wall 2b, and an engaging claw is provided at the free end of the upper side wall 2c. A receiving part 7 for engaging and disengaging the harness 6 is integrally formed, and the engagement between the engaging claw 6 and the receiving part 7 allows the harness to be held inside itself in a state surrounded by each side wall.

In addition, each lower fixing piece 4 has a stepped portion 8 whose tip is bent toward the upper fixing piece 3, so that the stepped portion 8 and the upper fixing piece 3 can sandwich the inner and outer sides of the inner panel. , near its own base and upper fixing piece 3
The bent hole edge of the insertion hole is introduced into the space 9 formed between them in accordance with its shape. Further, the upper fixing piece 3 is provided with an engagement hole 10 into which a locking leg formed integrally with the binding band, which will be described later, is inserted.

Therefore, when protecting the harness H from the bent hole edge of the insertion hole using the protection clip 1 having the above structure, the harness H is held in the insertion part 2 and the upper fixing piece 3, the lower fixing piece 4, While guiding the bent hole edge 11a of the insertion hole 11 between the upper and lower fixing pieces 3, 4,
4, sandwich the inner and outer sides of the inner panel P, and
As shown in the figure, if the fitting part 2 is attached to the part of the insertion hole 11 that may come into contact with the harness H, the harness H can be attached to each side 2a, 2b, 2c, 2d of the fitting part 2.
Due to the presence of the bending hole edge 11a of the insertion hole 11, there is no direct contact with the bent hole edge 11a of the insertion hole 11. Incidentally, such attachment is in a temporary state of the clip 1. In addition, when holding the harness H with the insertion part 2, as described above, use the clip 1.
In addition to holding the clip 1 in advance before attaching it, it is also optional to attach the clip 1 first and then hold it via the opening/closing side wall 2b depending on the implementation.

Next, the harness H is bound through the engagement hole 10 of the upper fixing piece 3 to the engagement hole 12 separately drilled at a proper location of the inner panel P, and the binding band 13 already attached to the harness H is tied. Locking leg 13a
3, the clip 1 is securely fixed to the inner panel P, and the harness H is also tied with the cable band 13 just before it is inserted into the insertion hole 11, as shown in FIG. It will be held at the fixed position of P.

Further, FIG. 4 shows another example of the protective clip according to the present invention, and the other example clip 1 has a pair of tongue pieces 14, 14 separated in the vertical direction at an interval on the outer surface of the opening/closing side wall 2b, as shown in the figure. so that when it becomes necessary to close the part of the insertion hole 11 to which the clip 1 is not attached with a sound insulating plate, the side end of the sound insulating plate can be inserted between the pair of tongue pieces 14 and held. It is composed of Incidentally, the configuration that can hold such a sound insulating plate also results in an even better fixing state of the clip 1 itself. The other configurations and operations are the same as those of the previous embodiment.

As described above, the present invention consists of an insertion part that is inserted into an insertion hole and holds the harness inside the insertion part, and upper and lower fixing pieces that are installed horizontally on one side wall of the insertion part and sandwich the inside and outside of the panel. In addition, since the protective clip is provided with an insertion hole in the upper fixing piece, the insertion part can be inserted into the insertion hole, and the protective clip can be attached to the panel through the upper and lower fixing pieces. By simply attaching the harness to the insertion hole, the harness is reliably protected from the bent edge of the insertion hole, so there is no need to worry about it being cut or damaged as in the past. or,
By engaging the locking legs formed integrally with the binding means such as a cable tie in the engagement holes of the upper fixing piece and the engagement hole of the panel, not only can the clip itself be securely fixed, but also Since it is also possible to bind and hold the harness immediately before insertion, the wiring condition of the harness is also much better than in the past.

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