Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing wiring such as a wire harness by using an unused hole among tap holes formed in advance in a vehicle body of an automobile or a cylinder block of an engine. It relates to a clip for wiring.

[0002]

2. Description of the Related Art In a clip of this type, a leg portion to be inserted into an unused tap hole is integrally formed with a base portion in which wiring such as a wire harness is held by, for example, tape winding. . And on these legs,
A plurality of fins are formed integrally along the axis. Each of these fins has a dish shape, and by inserting a leg portion into the tap hole, the outer peripheral edge of each fin engages with the thread groove of the tap hole due to its flexibility. Therefore, after the wire harness is held on the base portion by tape winding or the like, the leg portion is inserted into the tap hole, whereby the wire harness is fastened to the body of the automobile.

[0003]

However, in this prior art, although the fin of the leg engages with the thread groove of the tap hole with elastic force, the outer diameter of the leg other than the fin is changed. Is smaller than the inner diameter of the tapped hole, a gap is generated between the screw thread and the top surface of the thread. As a result, when the clip receives vibration, the leg moves in the radial direction against the tap hole against the elastic force of the fin, and the clip rattles.

[0004] An object of the present invention is to secure sufficient flexibility required for a fin portion which engages with a thread groove of a tap hole when a leg portion of the clip is inserted into the tap hole.
An object of the present invention is to prevent the leg from rattling with respect to the tap hole in the radial direction.

[0005]

According to a first aspect of the present invention, there is provided a wiring clip for fastening a wiring by using a tap hole formed in a counterpart member of a predetermined wiring in advance. A rod-shaped leg that can be inserted, and a base that is formed integrally with the leg and that can hold the wiring, the leg elastically engages a thread groove of the tap hole. And a columnar portion having an outer diameter in contact with the top surface of the screw thread in the tap hole. Therefore, when the leg portion of the clip is inserted into the tap hole, the fin portion engages with the thread groove of the tap hole, and the columnar portion comes into contact with the top surface of the thread of the tap hole. The radial movement of the part is prevented. This ensures sufficient flexibility of the fin portion required when inserting the leg portion into the tap hole, and prevents rattling of the clip.

According to a second aspect, in the wiring clip according to the first aspect, the fin portion is divided in the circumferential direction of the leg portion, and the columnar portion is formed on the outer peripheral portion of the leg portion except for the fin portion. It is characterized by being. A third invention is characterized in that, in the wiring clip of the first invention, the fin portions and the columnar portions are formed alternately along the axis of the leg portion.

[0007]

Embodiments of the present invention will be described below. Embodiment 1 FIG. 1 is a perspective view showing the appearance of a wiring clip. As shown in this drawing, the clip is a flat base portion 10.
And a leg 2 integrally formed on the lower surface of the base 10.
0. The base portion 10 and the leg portion 20 are integrally molded from a resin material.

On the upper surface of the base portion 10, a wire harness 14, which is a wiring of an automobile, is held in a connected state by tape winding. The leg portion 20 can be inserted into an unused tap hole 30 which is formed in advance on a vehicle body, a cylinder block, or the like. The wiring is not limited to the wire harness 14 but may be a single wire, and the means for holding the base 10 and the wiring is not limited to tape winding.

FIG. 2 is a structural view showing a part of the wiring clip, and FIG. 3 is a sectional view taken along line AA of FIG. As is apparent from these drawings, the leg portion 20 includes a plurality of fin portions 24 formed at a predetermined pitch along the axis of the shaft portion 22 integrally connected to the base portion 10. Each of the fin portions 24 has a thin-walled shape projecting outward from the shaft portion 22, and each of the fin portions 2.
4 has flexibility based on the elasticity of the resin material.

As shown in FIG. 2A, each of the fin portions 24 is divided into two in the circumferential direction of the leg portion 20. The outer peripheral portion of the shaft portion 22 excluding these fin portions 24 is a columnar portion 28 that is continuous in the axial direction of the leg portion 20 as is clear from FIG. And FIG.
The outer diameter D1 of the fin portion 24 shown in (A) is set to be substantially the same as the diameter of the thread groove of the tap hole 30 shown in FIG. The diameter is set to be approximately the same as the diameter.

As shown in FIG. 1, when the leg 20 is inserted into the tap hole 30 after holding the wire harness 14 on the base portion 10 by tape winding, the tip portion 25 of each fin portion 24 is Resiliently engages the thread groove. Moreover, at this time, the outer peripheral surface of the columnar portion 28 comes into contact with the top surface of the thread of the tapped hole 30 without any gap. As a result, the movement of the leg portion 20 in the radial direction with respect to the tap hole 30 is restricted, and the clip is secured in a state where the flexibility of the fin portion 24 necessary for inserting the leg portion 20 into the tap hole 30 is secured. Prevents rattling.

Embodiment 2 FIG. 4 is a partial sectional view showing a modification of the leg portion 20. In the present embodiment, a plurality of fin portions 44 and columnar portions 48 are alternately formed along the axis of the leg portion 20. That is, the individual fin portions 44 and the columnar portions 48 are both formed over the entire circumference of the leg portion 20, and each fin portion 44 has a thin dish shape projecting outward from the shaft portion 42, Each columnar portion 48 is a shaft portion 4
2 protrudes from the outer periphery in a cylindrical shape.

When the leg portion 20 is inserted into the tap hole 30 shown in FIG.
5 resiliently engages with the thread groove of the tap hole 30, and the outer peripheral surface of each of the columnar portions 48 contacts the top surface of the thread of the tap hole 30. Thus, similarly to the first embodiment, the movement of the leg portion 20 in the radial direction with respect to the tap hole 30 is restricted, and the play of the clip is prevented.
