[Industrial applications]

 TECHNICAL FIELD The present invention relates to a clip attachment structure for a T stud for attaching a clip for stopping a wire harness or the like to a T stud fixed to a vehicle body panel, for example.

[0002]

[Prior art]

 Conventionally, as this type of clip mounting structure, for example, a large diameter hole through which the head of the T stud is inserted and a small diameter hole into which the head of the T stud cannot be inserted are connected to each other in a flat plate-shaped portion of the clip body. Some have a Daruma hole. When mounting the clip body, first insert the head of the T stud through the large diameter hole, and then slide the clip body to move the shaft portion of the T stud to the small diameter hole. As a result, the clip body is attached to the T-stud in a state in which it does not come off. As another structural example, the clip body is formed into a cylindrical shape into which a T-stud can be inserted, and an inner peripheral portion thereof is provided with an engaging portion capable of engaging with the head of the T-stud. There is. By inserting the T stud, the engaging portion is elastically deformed so as to pass the head, and thereafter, the engaging portion is held in the engaged state with respect to the head. As a result, similar to the above, the clip body is in a state of being prevented from coming off from the T stud.

[0003]

[Problems to be solved by the device]

 In the structure where the clip body is provided with the above-mentioned “Dharma hole”, as described above, the T stud is inserted into the large diameter hole of the clip body and the shaft portion of the T stud is moved to the small diameter hole. Without this, the clip body cannot be attached, and workability is poor. Further, when the cylindrical clip body is used, since the engaging portion is elastically deformed when the T stud is inserted, the insertion resistance is increased and the workability is poor, and the clip body needs to be removed. In some cases the clip body must be destroyed.

The technical problem of the present invention is that the T-stud can be attached to the T-stud by simply inserting the T-stud into the stud insertion hole of the clip body, and the clip body can be removed from the T-stud if necessary. The clip body can be removed, which improves the workability for attaching the clip body and enables the clip body to be used repeatedly.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the clip mounting structure for the T-stud of the present invention is constructed as follows. That is, the clip mounting structure is such that the clip body is mounted to the T stud fixed at a predetermined position in a state where the clip body is prevented from coming off in the axial direction, and the T stud can be inserted into the clip body. And a slit formed so that the inner diameter of the stud insertion hole can be expanded with respect to the clip body, and a slit formed in a part of the clip body. An operating portion capable of elastically deforming the clip main body in the direction of expanding the inner diameter of the stud insertion hole, and an inner peripheral portion of the stud insertion hole formed to be axially engageable with the head of the T-stud. The engaging portion and the tapered guide surface formed on the insertion side of the T-stud in the engaging portion.

[0006]

[Action]

 According to this structure, when the T stud is inserted into the stud insertion hole of the clip body, the head of the T stud hits the guide surface of the engaging portion, and the action of the head and the guide surface causes the head of the T stud to contact. The T-stud is inserted while expanding the inner diameter of the stud insertion hole. Then, the head of the T-stud advances along the guide surface, and when it gets over the engaging portion, the stud insertion hole returns to the original diameter, and the engaging portion and the head engage with each other. This ensures that the clip body is firmly attached to the T-stud. When it is necessary to remove the clip body from the T-stud, the inner diameter of the stud insertion hole can be expanded by applying an external force to the operation portion of the clip body. Therefore, the engagement between the engaging portion and the head of the T-stud is released, and the clip body can be easily removed from the T-stud.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Example 1 FIG. 1 shows a part of the clip body 10 in a plan view, and FIG. 2 shows a sectional view taken along the line AA of FIG. Further, FIG. 3 is a perspective view of the clip body 10 as viewed from the lower surface side thereof. The clip body 10 is formed of a resin material or the like into a flat plate shape, and a stud insertion hole 12 penetrating the upper and lower surfaces thereof is formed in a part thereof. A portion of the clip body 10 (not shown) can be clamped for a wire harness or the like. Further, a T stud 52 for mounting the clip body 10 is fixed to a body panel 50 such as a vehicle shown in FIG.

A slit 14 is formed substantially at the center of the clip body 10 so as to extend from its end face to the predetermined position through the center of the stud insertion hole 12. The slit 14 allows the clip body 10 to be elastically deformed so as to expand the inner diameter of the stud insertion hole 12. In addition, an arch-shaped connecting portion 20 that straddles the opening end of the slit 14 is integrally formed on the end surface of the clip body 10. The connecting portion 20 also has elasticity, and by pushing the middle portion thereof toward the end face side of the clip body 10, the clip body 10 is forcibly elastically deformed in the direction of expanding the inner diameter of the stud insertion hole 12. Therefore, in this embodiment, the connecting portion 20 serves as an operating portion for forcibly expanding the inner diameter of the stud insertion hole 12.

The T stud 52 is inserted into the stud insertion hole 12 as will be described later. The T stud 52 is inserted into the stud insertion hole 12 on the side where the T stud 52 is inserted. The engaging portion 16 projecting to the front is integrally formed. The surface (lower surface) on the side where the T stud 52 is inserted in the engaging portion 16 is a tapered guide surface 17 on which the head 54 of the T stud 52 abuts and is guided. The surface (upper surface) on the side opposite to is the engagement surface 18 that engages with the head 54.

When the clip body 10 is attached to the T stud 52 in the above structure, when the T stud 52 is inserted into the stud insertion hole 12 of the clip body 10, as shown in FIG. The head 54 of the T-stud 52 contacts the guide surface 17 of the engaging portion 16. After that, the head 54 moves along the tapered shape of the guide surface 17 to expand the inner diameter of the stud insertion hole 12, and when the head 54 of the T stud 52 has passed over the engaging portion 16, the stud insertion hole 12 is removed. Returns to the original diameter as shown in Fig. 4 (B). As a result, the engaging surface 18 of the engaging portion 16 engages with the head 54, and the clip body 10 is attached to the T stud 52.

When removing the clip body 10 from the T-stud 52, an external force F is applied to the intermediate portion of the connecting portion (operating portion) 20 formed on the clip body 10 as shown in FIG. The inner diameter of the insertion hole 12 is forcibly expanded. Therefore, the engagement between the engagement surface 18 of the engagement portion 16 and the head 54 of the T stud 52 is released, and the clip body 10 can be removed from the T stud 52.

A slit 34 is formed on a part of the peripheral wall of the clip body 30 between the upper and lower end surfaces including the flange 42. However, a part of the slit 34 is joined by the connecting portion 40. An engagement portion 36 having the same shape as that of the first embodiment is integrally formed on the inner peripheral portion of the stud insertion hole 32 on the side opposite to the flange 42.

Also in the present embodiment, when the T stud 52 shown in FIGS. 1 and 9 is inserted into the stud insertion hole 32, the head 54 of the T stud 52 causes the guide surface 37 of the engaging portion 36 to move. Along which the inner diameter of the stud insertion hole 32 is expanded. Then, the head 54 of the T stud 52 gets over the engagement portion 36, and the diameter of the stud insertion hole 32 returns to the original diameter, so that the engagement surface 38 of the engagement portion 36 and the head 54 are engaged with each other. Further, as shown in FIG. 10, by applying an external force F to the flange 42 on both sides of the slit 34, the clip body 30 is elastically deformed so as to expand the inner diameter of the stud insertion hole 32. As a result, the engagement between the engagement surface 38 of the engagement portion 36 and the head 54 of the T-stud 52 is released, and the clip body 30 can be removed from the T-stud 52.
