JP 2001-330016 A

A conventional clip for mounting a member such as a connector on a panel of an automobile body has a saw blade-like hook formed on the engaging portion by inserting the engaging portion into a mounting hole formed in the panel. Is fixed by hooking the edge of the mounting hole. However, for example, a panel such as a truck is as thick as about 10 mm, and the edge of the mounting hole of this panel can be rounded or chamfered, and it becomes difficult to secure a catching margin due to this rounding or chamfering. Holding power becomes difficult to work. Further, since the roundness or chamfering of the edge of the mounting hole of the panel is more easily performed as the panel becomes thicker, the range of the panel thickness to which the clip can be applied becomes narrower.
Accordingly, an object of the present invention is to provide a clip having a wide range of applicable panel thicknesses.

In order to solve the above-mentioned problem, the invention according to claim 1 is a clip made of synthetic resin for mounting a member to be mounted on a panel of an automobile, and the mounting portion to which the member to be mounted can be mounted; An engagement portion that is attached to the panel by being inserted into an attachment hole provided in the panel, and the engagement portion includes a trunk portion that can be inserted into the attachment hole, and a plurality of steps in the length direction of the trunk portion. Each locking claw having a locking portion that protrudes outward from the outer peripheral surface of the trunk portion in its free state and can be locked to the edge of the mounting hole in that state. It is a clip.
In this way, by providing a plurality of stages of locking claws in the engaging portion, each locking claw is independent of each other, although it can accommodate a wide range of panel thickness panels. Can be locked to the edge of the mounting hole. Thereby, a clip can be latched in the attachment hole of a panel with a wide range of plate thickness.

Further, the invention according to claim 2 is the invention according to claim 1, wherein each of the engaging claws of the engaging portion is individually paired on the left and right, and adjacent to each other in the longitudinal direction of the trunk portion. Is arranged so as to be shifted from each other in the circumferential direction of the trunk.
In this way, each locking claw makes a pair, so that the locking state of the locking claw with respect to the mounting hole of the panel becomes more stable, and the adjacent locking claw in the length direction of the trunk portion extends in the circumferential direction. By shifting the position, more locking claws can be arranged in multiple stages on the trunk portion of a certain length. Therefore, it is possible to lock the clip to a panel having various plate thicknesses.

According to the first aspect of the present invention, the clip can be locked in the mounting hole of the panel having a wide range of plate thickness.
Furthermore, according to the invention described in claim 2, in addition to the effect of the invention described in claim 1, since more locking claws can be arranged in multiple stages, it is possible to lock the clip to a panel of various types of plate thickness it can.

  The best mode for carrying out the present invention will be described below with reference to the drawings. 1 shows the front of the clip of this embodiment, FIG. 2 shows the right side of the clip of FIG. 1, FIG. 3 shows the plane of the clip of FIG. 1, and FIG. 4 shows the IV-IV of the clip of FIG. The cross section is shown with the clip in use. As shown in these drawings, the clip 1 is an integrally molded product made of a synthetic resin including an engagement portion 2 and an attachment portion 3. For example, the engaging portion 2 is a portion that is inserted into a circular mounting hole 5 formed in the frame 4 of the track body shown in FIG. 4, and the mounting portion 3 is attached to a vehicle-mounted connector or the like. It is a part for attaching a member (not shown).

  As shown in FIGS. 1 and 2, the engaging portion 2 includes a trunk portion 6 and a plurality of locking claws 7 integrated with the trunk portion 6, and the respective locking claws 7 are independent of each other. The base portion of the trunk portion 6 is the base portion of the engaging portion 2, and as shown in FIG. 3, the end portion 8 of the trunk portion 6 has an annular end surface, and the engaging portion 2 is inserted into the mounting hole 5. It has a function to correct misalignment.

  As is apparent from FIG. 4, the trunk 6 is formed in a hollow cylindrical shape having a thickness that allows the attachment hole 5 to be inserted, and an axial length protruding from the attachment hole 5. The locking claws 7 are individually paired on the left and right sides, and the adjacent locking claws 7 in the longitudinal direction of the trunk 6 are arranged so as to be shifted from each other in the circumferential direction of the trunk 6. And three sets of latching claws 7 are provided with a pair of the latching claws 7 facing in opposite directions as one set, and three stages are formed at intervals from the distal end portion 8 side of the trunk portion 6 to the base portion. . The cross-sectional shape of each locking claw 7 has a deformed triangular shape as shown in FIG. The base portion of each locking claw 7 is a joint portion integrated with the trunk portion 6, and this portion is a self-thinning 9 that is slightly thin.

As shown in FIGS. 1 and 2, both side ends and the tip of each locking claw 7 are separated from the trunk 6, and the entire locking claw 7 is elastically bent inwardly of the trunk 6 at the self hinge 9. can do.
As shown in FIG. 4, each locking claw 7 protrudes outward from the outer peripheral surface of the trunk portion 6 in a free state, and engages with the edge portion 5 a of the mounting hole 5 and the base portion direction of the trunk portion 6. 6 and an inclined surface 11 inclined outward. Even if the locking claw 7 is protruded outward, even if the edge 5a of the mounting hole 5 is rounded or chamfered, the locking portion 10 of the locking claw 7 exceeds the rounded or chamfered surface and has a predetermined holding force. The dimensions are set to obtain. The locking portion 10 is configured in a plane substantially perpendicular to the central axis of the trunk portion 6 and is coupled to the subsequent skirt portion 12 at an obtuse angle (approximately 135 degrees). Each latching claw 7 is elastically bent to the position of the outer peripheral surface of the trunk 6 at the self hinge 9 when the inclined surface 11 receives a force from the outside.

  A plate-like stabilizer 13 is formed at the base of the trunk 6 so as to extend from the base integrally to the distal end side and greatly expand outward. As shown in FIG. 3, the stabilizer 13 is formed with substantially V-shaped slits 14 extending in the radial direction at two opposing positions. As shown in FIG. 4, the stabilizer 13 is pushed and elastically deformed by the one surface 4 a of the frame 4 when the engaging portion 2 is inserted into the mounting hole 5 from the one surface 4 a of the frame 4. However, the structure is in contact with the one surface 4a of the frame 4, and by providing the slit 14, the moldability is improved, the elastic deformation is easily performed, and the adhesion to the one surface 4a of the frame 4 is also improved.

  The clip 1 is fixed to the frame 4 by inserting the engaging portion 2 into the attachment hole 5 of the frame 4, and a member to be attached such as a connector can be attached to the attachment portion 3. By inserting into the attachment hole 5 from the distal end side of the trunk portion 6, the locking claw 7 of the engagement portion 2 is pressed against the inclined surface 11 from the outside by the attachment hole 5. It is elastically bent to the outer diameter and extracted from the edge 5a on the other surface 4b side. The extracted locking claw 7 is in a free state, is restored by elastic force, protrudes greatly in the radial direction from the trunk portion 6, and even if the edge 5 a of the mounting hole 5 is rounded or chamfered, the locking portion 10 causes the edge 5 a to move to the edge 5 a. Locked and fixed.

Furthermore, by providing a plurality of stages of latching claws 7 in the engaging portion 2, each latching claw 7 is independent of each other even though it can cope with the frame 4 with a wide range of plate pressures. The locking portion 10 of the pawl 7 can be locked to the edge 5 a of the mounting hole 5. Specifically: When the frame 4 is thick, the middle and lower engaging claws 7 shown in FIG. 4 stop in the mounting hole 5 while being elastically bent in the mounting hole 5. The locking claw 7 that does not act on the locking also continues to exert an elastic force on the mounting hole 5 and stabilizes the position of the trunk 6. The middle level claw 7 will act on the middle thickness frame 4, and the lower level claw 7 will act on the thinner frame 4. In any case, the stabilizer 13 is brought into close contact with the one surface 4a of the frame 4, and the elastic force is applied to the locking portion 10 of the locking claw 7 against the edge 5a of the mounting hole 5 on the other surface 4b side of the frame 4. Since it works to attach, the fixed state to the frame 4 is reliably maintained.
Further, the stabilizer 13 itself has a plate thickness absorbing action. For example, in FIG. 4, when there is a slight change in the thickness of the frame 4, the change is absorbed by a change in the amount of deflection of the stabilizer 13. The slit 14 is for bending the stabilizer 13 in a wide range and absorbing the plate thickness. Such a function of the stabilizer 13 is also exhibited in each locking claw 7 in the same manner. Therefore, in the range where the clip 1 can be applied by the combination of each locking claw 7 and the stabilizer 13, a plate thickness that is steplessly equal. Can cope with change.
Furthermore, since each latching claw 7 forms a pair, the latching state of the latching claw 7 with respect to the mounting hole 5 of the frame 4 is further stabilized, and the latching claw 7 adjacent in the longitudinal direction of the trunk 6 is also provided. By shifting in the circumferential direction, more locking claws 7 can be arranged in multiple stages on the trunk 6 having a certain length.

  Although the above embodiment includes the three-stage locking claw 7, the present invention is not limited to this, and the number of stages of the locking claw 7 can be increased to be applicable to the frame 4 having various plate thicknesses. You can do it.

  The present invention can remarkably widen the usable range of a clip to be locked to a panel in the automobile industry or the like.

It is a front view of the clip of this Embodiment. It is a right view of the clip of FIG. It is a top view of the clip of FIG. It is sectional drawing which showed the IV-IV cross section of the clip of FIG. 3 in the use condition of a clip.
