Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a detent locking leg for mounting a board holding a wire harness or a protector for protecting the wire harness to a panel such as a vehicle body. Is.

[Prior Art] Japanese Patent Application Laid-Open No. 59-29808 discloses a structure of a locking leg for mounting a clip for a weather strip in a hole of a panel such as an automobile door. That is, according to this publication, a pair of struts are formed projectingly from the clip substrate, and elastic engaging arms extending from the respective struts substantially parallel to the surface of the substrate are formed.

The support pillars are inserted into the holes of the panel while bending the elastic engagement arms inward. The clip board is attached to the panel by stopping the engagement protrusion formed on each engagement arm at the edge of the hole.

[Problems to be Solved by the Invention] In the above-mentioned publication, even if the holes of the panel are formed as square holes and the clip substrate is prevented from being rotated only by the locking legs, the respective angular elastic engaging arms have their respective positions. Since it is integrated with the substrate only at the column, the substrate is apt to wobble in the rotation direction, and its orientation is not stable. However, if the rigidity of the engaging arm is increased, it becomes extremely difficult to insert the support column into the hole of the panel.

[Means for Solving the Problems] In order to solve the aforementioned problems, the detent locking leg of the present invention is configured as follows.

That is, the locking leg is formed in a state of protruding from a substrate mounted on a predetermined panel, and is non-rotatably inserted and mounted in an angular or elliptical mounting hole formed in the panel. .

The locking leg has a pair of struts projecting from the base plate in a mutually opposed manner at regular intervals, a connecting beam connecting the ends of these struts to each other, and one of the struts, the substrate and the connecting beam. And the wall body in which the three edges corresponding to the above are individually integrated with each other, and only the remaining one edge is the free end, and the wall body is formed integrally with the wall body at a portion near the free end of the wall body. And a locking claw capable of locking the peripheral edge of the mounting hole of the panel.

[Operation] According to the above configuration, when the locking leg is inserted into the mounting hole of the panel, the locking claw passes over the peripheral portion of the mounting hole due to the bending of the free end side of the wall body, and the opposite side. Elastically lock to. The columns connected to each other by connecting beams are located on both sides of the wall, and the walls are integrated with other members as described above at the three edges except for the free ends. The rigidity of the whole body is secured. Therefore, when the locking leg is inserted in the mounting hole of the panel, it is possible to sufficiently cope with the external force applied to the substrate in the rotation direction.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

First Embodiment In FIGS. 1 to 6, the substrate 10 is formed of a material such as synthetic resin into a plate shape elongated in one direction. A wire harness (not shown) or a protector (not shown) that protects the wire harness is secured to one side surface (upper surface in FIG. 6) of the board 10 by, for example, tape winding, and the board 10 holds these. It functions as an ingredient.

On the board 10, a locking leg 40 is integrally formed on the surface opposite to the surface on which the wire harness or the like is stopped. Therefore, the locking leg 40 will be described. First, as apparent from FIGS. 1 to 5, a pair of support columns 12 and 13 are integrally formed on the substrate 10. These pillars 12 and 13 project in a mutually opposed manner with a constant space therebetween. Further, the tip ends of both columns 12, 13 are connected to each other by a connecting beam 14 formed integrally with them. Connection beam 14
The peripheral side surface is a sloped surface 16 having a shape expanding downward in FIGS. 1, 3, and 4.

For example, as is clear from FIG. 5 showing a cross section taken along the line VV of FIG. 3, the columns 12, 13 and the connecting beam 14 are provided on both sides (upper and lower sides in FIG. 5) of the columns 12, 13. A pair of wall bodies 18 and 19 are formed so as to each have an L-shaped cross section. These walls 18 and 19 are thinner than the substrate 10, columns 12, 13 and connecting beam 14. Moreover, each wall
18, 19 has three edges corresponding to one of the columns 12, 13 and the substrate 10 and the connecting beam 14, respectively, which are individually integrated with each other, and only the remaining one edge is the free ends 18a, 19a. Has become. Also, at the locations near the free ends 18a, 19a of the wall bodies 18, 19,
The locking claws 20 and 21 are integrally formed.

FIG. 6 shows a panel 30 such as a vehicle body to which the locking leg 40 having the above-described structure is attached, and a square-shaped attachment hole 32 formed in the panel 30. Locking claws 20 and 21 of the walls 18 and 19
When the locking leg 40 is inserted into the mounting hole 32 of the panel 30, the locking leg 40 can be locked to the peripheral edge of the mounting hole 32.

In the above structure, the substrate 10 has the sixth
A wire harness or a protector in a state where the wire harness is protected is fixed to the upper surface in the illustrated state by tape winding or the like. Then, the locking leg 40 is inserted into the mounting hole 32 of the panel 30. At this time, the locking leg 40 is guided by the slope 16 of the connecting beam 14 and smoothly inserted into the mounting hole 32. Then, in this insertion process, the wall body
Due to the bending of the free ends 18a, 19a of the 18, 19, the locking claws 20, 21
Rides over the peripheral edge of the mounting hole 32 and is elastically locked to the opposite side.

In this manner, with the locking leg 40 inserted in the mounting hole 32 of the panel 30, the columns 12 and 13 are located on both sides of the walls 18 and 19, and the columns 12 and 13 are connecting beams 14. The two walls 18 and 19 are connected to each other, and the three edges except the free ends 18a and 19a are integrated with one of the columns 12 and 13, the substrate 10 and the connecting beam 14 as already described. There is. Therefore, the rigidity of the locking leg is sufficiently ensured, and it is possible to withstand the external force applied to the substrate 10 in the rotation direction.

Second Embodiment FIG. 7 shows a locking leg of the second embodiment in a sectional view corresponding to FIG. In this embodiment, the mounting hole for the panel 30 is used.
32 is an elliptical shape, and the outer surfaces 12a and 13a of the columns 12 and 13 are arcuate curved surfaces in accordance with the shape of the mounting holes. The rest of the configuration is the same as that of the first embodiment, so redundant description will be omitted.

[Advantage of the Invention] According to the present invention, since the three edge portions of the wall body are integrated with other members and the remaining one edge portion is the free end having the locking claw, the wall body is Although the part that has the locking claws is flexible, the rigidity is secured as a whole, so that the locking legs can be easily inserted into the mounting holes of the panel, and after the insertion, the external force in the rotation direction applied to the board is applied. You can deal with it sufficiently.
