BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings.
1 to 6 are views showing an embodiment of the clip according to the present invention. FIGS. 1 to 4 are explanatory views for explaining the structure, and FIGS. 5 and 6 are views for explaining the work of mounting and removing the clip. FIG. In the present embodiment, the same components as those in the above-described related art are denoted by the same reference numerals, and description thereof will be simplified.
[0010]
First, the configuration will be described.
1 to 3, the clip includes a clip main body 10 and an auxiliary member 20. The clip main body 10 includes a plate-shaped portion 11 and an engagement portion 12, while the auxiliary member 20 includes a rod-shaped portion 21 and A spherical portion 22 is provided.
The clip body 10 is fixed by winding a tape T around a wire harness (attachment member) W on which a plate-like portion 11 is wired around a body panel (attachment member) B of a vehicle body. The engaging claw 14 is engaged with the edge of the mounting hole H opening to the B, and the wire harness W is fixed at the position of the mounting hole H. It is made of a resin material having properties. That is, the plate-like portion 11 constitutes a fixing member.
[0011]
The engaging claw 14 has an area in which the spherical portion 22 of the auxiliary member 20 can be inserted, and eight pieces of substantially the same shape are erected around the through hole 13 opened in the plate-shaped portion 11. Is formed so as to have an outer surface smaller than the mounting hole H of the panel B before being assembled with the auxiliary member 20, and in this state, the engaging claw 14 is moved until the panel B comes into contact with the lower surface of the plate-shaped portion 11. It can be inserted into the mounting hole H. It is needless to say that the number of the engaging claws 14 is not limited to eight, and it is sufficient that two or more engaging claws 14 are formed so as to be expandable by the spherical portion 22 of the insertion member 20.
[0012]
Each of the engaging claws 14 is formed in a substantially similar shape, and has a base 14a on the plate-like portion 11, an intermediate portion 14b adjacent to the base 14a, and a diaphragm on the distal end adjacent to the intermediate portion 14b. A space 16 into which the spherical portion 22 of the auxiliary member 20 is inserted is defined on the inner surface side by the portion 14c, and the base portion 14a has substantially the same cross-sectional area as the through-hole 13 and has a cylindrical 0th shape connected to the through-hole 13. The space 16a, the intermediate portion 14b has a smaller cross-sectional area than that of the zero space 16a, the cylindrical first space 16b connected to the zero space 16a, and the throttle portion 14c has a first cross section that gradually narrows the cross sectional area. A conical second space 16c is provided continuously with the space 16b. That is, the auxiliary member 20 constitutes the insertion member, and the spherical portion 22 constitutes the tip. Note that the tip of the auxiliary member 20 is formed in a spherical shape in the present embodiment, but another shape that expands the engaging claw 14 is also conceivable .
[0013]
Accordingly, the clip body 10, as shown in FIG. 4 (a), the through hole within 13 of the clip body 10 end of the auxiliary member 20 after inserting the spherical portion 22 into (the 0th space 16a) (grip portion) further inserting gripping the 21a, because it is smaller form the inside surface than the first space 16b thereof spherical portion 22 the intermediate portion 14b of the engaging claw 14 is defined, as shown in FIG. 4 (b) The intermediate portion 14b is separated from each other due to the elastic deformation of the base portion 14a and expands to allow the spherical portion 22 to be inserted, thereby increasing the outer surface of the intermediate portion 14b. When the spherical portion 22 is inserted until the spherical portion 22 comes into contact with the narrowed portion 14c, the narrowed portion 14c is formed so as to narrow the second space 16c, so that further movement of the spherical portion 22 is restricted.
[0014]
Next, attachment and detachment of the wire harness W to and from the body panel B of the vehicle body will be described with reference to FIGS.
First, as shown in FIG. 5A, the clip body 10 and the auxiliary member 20 are prepared, and the auxiliary body 20 is extended from the through hole 13 of the clip body 10 to the first space 16b defined by the intermediate portion 14b of the engaging claw 14. As shown in FIG. 5B, the spherical portion 22 of the member 20 is inserted, and the base portion 14a is elastically deformed so that the intermediate portion 14b is expanded. Next, as shown in FIG. 6A, the plate-shaped portion 11 is fixed to the wire harness W wound with the tape by the tape T. At this time, since the intermediate portion 14b and the squeezed portion 14c of the clip body 10 are held in contact with the outer surface of the spherical portion 22, the auxiliary member 20 does not fall off from the clip body 10 and, for example, a wire The plate-like portion 11 can be fixed through the rod-like portion 21 in the harness W. The clip body 10 and the auxiliary member 20 may be prepared in a state where they are combined in advance as shown in FIG.
[0015]
Next, the end portion 21a of the rod portion 21 is gripped and pulled out so that the spherical portion 22 is located in the zero space 16a defined by the base portion 14a of the clip body 10. Therefore, the engagement claws 14 can be inserted into the mounting holes H of the body panel B.
Next, as shown in FIG. 6B, after the engaging claws 14 are inserted into the mounting holes H of the body panel B to bring the panel B into contact with the lower surface side of the plate-shaped portion 11, the bar-shaped portion 21a is gripped. Then, the spherical portion 22 is inserted until the movement thereof is restricted by the narrowed portion 14c of the engaging claw 14, and the base portion 14a is elastically deformed again to expand the intermediate portion 14b as shown in FIG. 6C. State. Therefore, the engaging claw 14 can prevent the outer surface from being detached by making the outer surface larger than the mounting hole H of the body panel B, and can also hold the body panel B between the engaging claw 14 and the lower surface of the plate-shaped portion 11. The wire harness W can be attached and fixed.
[0016]
On the other hand, when removing the wire harness W from the body panel B, on the other hand, the bar-shaped part 21 is gripped and the spherical part 22 is pulled out in the direction of the plate-shaped part 11, and as shown in FIG. And the engaging claw 14 can be easily pulled out from the mounting hole H of the body panel B. Therefore, when disassembling the vehicle body, the wire harness W, the clip body 10 and the auxiliary member 20 can be removed simply by gripping and pulling the rod-shaped portion 21a.
[0017]
As described above, in the present embodiment, the outer surface of the engaging claw 14 is merely held by gripping the auxiliary member 20 and inserting / pulling out the spherical portion 22 in the through hole 11 and the engaging claw 14 of the clip body 10. The engaging claws 14 can be engaged / disengaged with the mounting holes H of the body panel B by expanding / reducing, and the wire harness W fixed to the plate-shaped portion 11 can be easily mounted / removed. . When removing the wire harness W, the clip itself can be removed from the body panel B together with the wire harness W.
[0018]
As another aspect of the present embodiment, although not shown, the base 14a slightly resiliently returns while the engaging claw 14 is expanded when the spherical portion 22 of the auxiliary member 20 is inserted. Thus, a depression may be formed between the intermediate portion 14b and the throttle portion 14c. As a result, the spherical portion 22 of the auxiliary member 20 can be held by the depression and the return can be reliably restricted.
[0019]
【The invention's effect】
According to the first and second aspects of the present invention, the distal end of the insertion member is smaller than the distal end defined by the inner surface of the engaging claw of the engaging portion through the through hole of the fixing member. By inserting / pulling out the connector, the outer shape of the engaging portion by the outer surface of the engaging claw can be expanded / reduced. Therefore, the fixing member is fixed to the mounting member, and the engaging claw is inserted into the mounting hole of the member to be mounted. After the insertion, by grasping the insertion member and inserting the distal end portion between the engagement claws, the outer surface of the engagement portion can be made larger than the attachment hole to fix the attachment member so that it cannot be pulled out. By pulling out the tip, the outer surface of the engaging portion is made smaller than the mounting hole, and the mounting member can be removed together with the clip. Therefore, the attachment member and the clip itself can be easily removed without using a cutting tool, and the burden at the time of dismantling work can be reduced. Further, when the first and second spaces having different cross-sectional areas are defined as spaces by the engagement claws, the movement of the distal end portion of the insertion member is restricted, and the engagement claws are reliably expanded. Can be maintained, and the reliability can be improved.
