Description

[Detailed Description of the Invention] The present invention relates to a protective member such as 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 tip of the bent hole edge due to vibrations during driving. Therefore, there were many cases of breakage.

For this reason, the applicant has provided a protective clip related to Utility Model Application No. 86448/1983 or Utility Model Application No. 86450/1983. However, in all of these protective clips, the clip body is formed into a shape that follows the shape of the insertion hole, and the clip body is fixed including the tip of the edge of the bent hole through a unique fixing means. Since it is attached to the insertion hole, the harness is completely protected, but the clip itself becomes large and increases the cost. It is undeniable that the installation work is complicated.

The present invention was devised in view of the shortcomings of such protective clips, and consists of a flexible protective tube made of synthetic resin, and a metal that is attached at regular intervals inside the flexible protective tube. The flexible protective tube has a continuous slit in the longitudinal direction into which the tip of the bent hole edge of the insertion hole drilled in the panel is inserted, and the clip body has an inverted U-shaped cross section. The above-mentioned drawbacks are effectively solved by providing a protective member having locking claws cut and raised inwardly on each of both side pieces.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment. The protection member according to the present invention includes a flexible protective tube 1 made of synthetic resin, and a fixed interval inside the flexible protective tube 1. The former flexible protective tube 1 consists of a metal clip body 2 that is attached to the panel as shown in FIG. The clip body 2 has an inverted U cross section formed by bending a thin metal piece in a predetermined punched shape, as shown in FIG. 2. The side pieces 4, 4 exhibiting a letter shape and forming the inverted U shape,
When the tip portions 4a, 4a are respectively expanded outward and installed inside the flexible protective tube 1, the expanded tip portions 4a, 4a can be locked to the inner wall surface of the tube near both sides of the slit 3. In addition, locking claws 5, 5 cut and raised inward from each other are formed on each of the side pieces 4, 4, and both sides of the bent hole edge of the insertion hole are secured by the both claws 5, 5. It has a structure that allows it to be held in place.

Therefore, when protecting the harness H from the tip of the bent hole edge of the insertion hole drilled in the inner panel using the protection member configured as described above, first, the protection member shown in FIGS.
As shown in FIG.
After attaching the slits 3 to the inner wall surfaces of the pipes near both sides of the slit 3 and bringing the upper ends into contact with the corresponding inner wall surfaces of the pipes, insert the insertion holes 6 formed in the inner panel P as shown in FIGS. 4A and 4B. If the bent hole edge tip 6a, which is a part of the bent hole edge that is likely to come into contact with the harness H, is inserted into the flexible protection tube 1 through the slit 3, the bent hole edge tip 6a is inserted into the flexible protective tube 1 through the slit 3. is inserted between the side pieces 4, 4 of each clip body 2, and the locking claws 5, 5 of the clip body 2 bite into both sides of the bent hole edge to hold the flexible protective tube. 1 will be definitely fixed.

Therefore, even if the harness H is later inserted into the insertion hole 6, the tip 6a of the edge of the bending hole is completely surrounded by the fixed flexible protective tube 1, so the harness H is inserted into the bending hole. There is no direct contact with the tip 6a of the edge.

When fixing the flexible protection tube 1 to the tip of the bent hole edge, as shown in FIG. If so, the flexible protective tube 1 itself may be bent along the curved shape and fitted. or,
The length dimension of the flexible protection tube 1 can be determined individually by forming the flexible protection tube 1 as a long body by extrusion molding in advance and cutting it according to the fixing area. A protected status will be obtained.

As described above, the present invention consists of a flexible protective tube made of synthetic resin and a metal clip body that is attached at regular intervals inside the flexible protective tube. A slit is formed continuously in the longitudinal direction into which the tip of the bent hole edge of the provided insertion hole is inserted, and the clip body has an inverted U-shape in cross section and is cut and raised inwardly on each of both sides. Since the protection member is provided with a locking pawl, the harness can be inserted through the insertion hole by simply inserting the tip of the bent hole edge of the insertion hole into the flexible protection tube in which the clip body is attached. Since the harness is protected from the tip of the bent hole edge of the hole, it is possible to reliably protect the harness with an extremely simple structure and simple work compared to the protection clips described above.

In addition, the fixed flexible protective tube can be easily removed by forcibly pulling it out from the tip of the bent hole edge of the insertion hole, so the fixed position can be easily changed if necessary.

Furthermore, the protective tube according to the present invention can be fixed to the tip of the bent hole edge of an insertion hole of any shape by utilizing its own flexibility, so it is extremely versatile and can be used easily. Since the protective tube has a shape suitable for mass production, it can also contribute to cost reduction in this respect.
