Description

[Detailed description of the invention] Industrial application field The present invention is a long member that attaches a long member such as a wire harness to a panel by locking a clip to a stud fixed to a panel of a vehicle body or the like. Regarding the mounting structure.

2. Description of the Related Art A typical clip for attaching a wire harness to a vehicle body is a plastic clip in which an arm portion for fixing the wire harness and an anchor leg-shaped vehicle body attachment portion are integrally molded. This clip is
The wire harness can be attached to the vehicle body by fixing the arm portion to the wire harness by wrapping tape or the like, and then pushing the attachment portion into a predetermined hole in the vehicle body, which has the advantage of simplifying the installation work. However, a hole must be provided in the vehicle body, which is not only necessary, but also causes the sound of water to leak from the hole, which is undesirable. Another disadvantage was that the wire harness rotated in an undesirable direction.

Problems to be Solved by the Invention Therefore, there is a desire for a clip that can easily attach a long member such as a wire harness to a vehicle body without drilling a hole in the vehicle body. Therefore, studs were welded onto the car body at designated locations, and these studs
I tried installing a clip that held the wire harness in place. However, the attached clip rotates around the stud, which does not solve the problem of bending the wire harness in an undesirable direction. This caused interference with other components in a narrow space, and also caused internal wires to break.

The above-mentioned conventional stud has a circular cross section and does not have a function to stop the stud from rotating against the clip, resulting in the undesirable bending of the wire harness as described above. Therefore, the inventors of the present invention proposed a stud having a rectangular cross section, a prismatic shape, and a clip locking portion provided on the side surface as a stud capable of preventing the rotation of the clip.

Therefore, an object of the present invention is to use a clip that is compatible with the stud having the above-mentioned rotation-stopping function, and thereby to attach a long member such as a wire harness in a predetermined correct direction without making a hole. be.

Means for Solving the Problems In order to achieve this purpose, according to the present invention,
A long member mounting structure in which a long member such as a wire harness is attached to a panel by locking a clip to a stud fixed to a panel of a vehicle body, etc., wherein the stud is a prismatic column with a rectangular cross section. The clip has locking claws formed on both sides of its short side, and a locking hole formed on its long side, and the clip has an arm portion to which a long member can be fixed. , an attachment part to the stud having a space with a rectangular cross section formed to receive the stud, and a locking part that engages with a locking pawl of the stud on the inner wall on the short side of the stud attachment part. is formed, and a locking protrusion that elastically projects inward and engages with a locking hole of a stud is formed on the inner wall of the long side. Ru.

Embodiment FIG. 1 shows a first embodiment of the clip according to the present invention. The clip 1 is formed by integrally molding a stud attachment part 2 and an arm part 5 for fixing a long attachment member such as a wire harness 3 with tape 4 or the like, and is preferably made of a plastic material for ease of molding.

The clip 1 is attached to a stud 7 which has a unique shape as shown by arrow 6. This stud 7
is welded and fixed to a panel 8 of a vehicle body or the like in a predetermined direction. Before explaining the clip 1 in detail, the stud 7 will be explained.

The stud 7 used in the present invention has a rectangular cross section (rectangular in the illustrated example) and extends in a prismatic shape, and its height can be determined arbitrarily. A hole 9 is provided on the side surface as a latching portion for the clip 1, and a latching claw 19 as a latching portion for the clip 1 is also provided on the surface without the hole 9 (short side surface). Also,
The hole 9 is for locking the clip 1,
A recess may be used instead of a hole. This stud has the advantage that it can be easily obtained by punching out a flat plate material such as a soft steel plate of a suitable thickness. Further, as mentioned above, since the stud 7 is formed into a prismatic shape, it is possible to prevent the attached clip from rotating.

The explanation will also be made with reference to The stud mounting part 2 is
A stud receiving hole 12 with a cross section adapted to the cross section of the stud 7 is formed in the center. Stud 7
A two-step locking shoulder 13 is formed on the inner surface of the short side corresponding to the locking pawl 10 of. The locking shoulder 13 may have one stage if the locking force is sufficient, or may have three or more stages depending on the locking strength. Further, a slit 14 is formed on the long side surface so as to give elasticity to the locking shoulder 13, so that the shoulder 13 bends outward when inserted into the stud 7.

Further, a locking protrusion 16 is formed on the long side surface of the clip 1 at a position corresponding to the locking hole 9 of the stud 7, and a U-shaped slit 17 is formed to give elasticity to the protrusion 16. . In addition, clip 1
The entrance 18 of the stud receiving hole 12 is tapered to facilitate insertion.

Therefore, after fixing the wire harness 3 to the clip 1, the wire harness 3, which is a mounting member, is fixed to the panel 8 via the clip 1 by simply inserting it in the direction of the arrow 6 in FIG. In this case, since the stud 7 is prismatic and the hole 12 in the clip 1 fits therein, the wire harness 3 will not rotate.

FIG. 3 shows a second embodiment of the clip according to the invention, and shows how this clip 20 is used to secure the wire harness 3 to the stud 7. This clip 20 is adapted to be locked from the side via the stud 7 as shown by arrow 21. For this reason, the clip 20 is
As shown in ~d, it is equipped with a stud attachment part 22 and an arm part 23, and a wire harness 3 is attached to the arm 23.
is fixed with tape 4 or the like. Stud mounting part 22
is formed into a U-shape with one side open so as to hold the stud 7 from the sides, and a hollow space is formed therein, and a locking shoulder 24 is formed to lock into the locking pawl 10 of the stud 7. and a protrusion 2 that locks into the hole 4.

After attaching the wire harness 3 to the arm 23, the clip 20 is inserted into the stud 7 in the direction of the arrow 21, thereby fixing the clip 20 to the stud and, in turn, fixing the wire harness 3 to the panel 8.

The clip of this second embodiment differs from the clip 1 in FIG.
It has the advantage that it can be removed from the

FIG. 5 shows a third embodiment of the clip according to the present invention. Also, the details of this clip are shown in Figure 6a.
~F is shown. This clip 30 is adapted to be engaged with the stud 7 from above as shown by an arrow 31. The clip 30 is shown in FIG. 6 a to f.
As shown in FIG. 2, the wire harness 3 is provided with a stud attachment portion 32 and an arm portion 33, and the wire harness 3 is fixed to the arm portion 33 with a tape 4. The stud mounting portion 32 has a stud receiving hole 34 formed in the center that matches the cross section of the stud 7 and surrounds the stud 7.

On the inner surface of the stud receiving hole 34, a thin piece 35 that is deformed by contacting the side surface of the stud 7 is formed in a vertically elongated manner at a position corresponding to the locking pawl 10 of the stud 7. This thin piece 35 prevents the clip 30 from rattling against the stud 7 when the clip 30 is pushed into the stud 7, and is preferably provided to an extent that does not significantly increase the force required for pushing. A stud receiving hole 3 is provided at a position corresponding to the locking hole 9 of the stud 7.
A locking protrusion 36 is formed that protrudes at 4. Similar to the first embodiment, a U-shaped slit 37 is formed on the long side surface of the stud attachment portion 32 so that the locking projection 36 can be bent outward. Therefore, in this example, only the locking protrusion 9 functions as the locking portion to the stud. The locking protrusion 36 is also provided with an outward extension 38 that protrudes outward, and when pressed, the entire protrusion 36 bends outward and comes off the locking hole 9 of the stud 7, allowing the clip 30 to be removed. It can be removed from stud 7.

In this example, the stud attachment portion 32 is formed to widen toward the bottom at its lower portion, thereby making it easier to push the stud into the stud and stabilizing the posture after attachment. It goes without saying that such a shape can also be applied to other embodiments.

The clip 30 in this embodiment has the advantage of being more removable than the clip 20 shown in the second embodiment.

Effects of the invention According to the invention, when attaching a long member such as a wire harness to a panel of a vehicle body, there is no need to drill holes in the panel, and furthermore, it is possible to prevent undesirable bending force from being applied to the mounting member. The clip prevents that rotation so that the member does not bend in an undesirable direction. Further, since the work of attaching the members is a simple work of pushing them together, work efficiency is also improved. Furthermore, according to the present invention, the stud is formed of a highly rigid prismatic column, and the clip is attached to this rigid prismatic column, so that the clip and, by extension, a long member such as a wire harness can be firmly fixed to the stud and even to a panel of the vehicle body. Not only does the locking protrusion of the clip engage with the locking hole of the stud, but also the locking portion of the clip engages with the locking pawl of the stud, so that the fixing force of the clip to the stud is extremely strong. In particular, even if the clip is moved up, down, left or right relative to the stud after connection, the connection will not come off, and even if the wire harness is moved by hand during assembly or repair, the connection will not come loose, and the connection will no longer come loose from the car body. There will be no more accidents of it coming off.
