BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness clip for fixing a wire harness to a vehicle body panel or the like.

[0002]

2. Description of the Related Art Conventionally, not only electronic equipment but also automobiles and the like have been provided with a large number of power supply wires and signal wires for connecting electrical components in a body panel as wire harnesses. When these wire harnesses are used without fixing a long interval to the body panel, they may be disconnected due to resonance with the vibration of the vehicle body, or the covering layer may be broken and short-circuited. It is necessary to fix to the body panel via the wire harness clip. Therefore, various clips have been used as clips for fixing the wire harness to the body panel.

For example, a clip for a wire harness disclosed in Japanese Utility Model Application Laid-Open No. 58-153525 and the like includes a rectangular mounting board attached to the wire harness,
An elastic projection for locking is provided on the mounting substrate so as to protrude from the mounting substrate and is mounted in a hole of the body panel, and is integrally formed of synthetic resin. When the wire harness is fixed to a mounting portion such as a body panel, the wire harness is wound around the mounting board using a tape or a band, and the like.
The clip for the wire harness and the wire harness are integrally fixed to the body panel by attaching the elastic projection for locking to the hole formed in the body panel while elastically deforming the same. The wire harness clip is configured such that an engaging portion of a locking elastic projection is engaged with an inner peripheral edge of the hole, and an elastic biasing force of the locking elastic projection is applied to the engaging portion in a locking direction. It is configured to prevent falling off.

Japanese Utility Model Laid-Open Publication No. 61-117908 discloses a clip fixing structure as shown in FIG. That is, the board 1 of the interior component such as the roof garnish
A square cylindrical mounting rib 11 is formed upright on the back surface 10a of the zero. On the other hand, the clip 12 is formed by bending a spring steel or the like into a substantially U-shape, and has a mounting portion 13 for fixing to the mounting rib 11 and an elastic fitting fitted into a mounting hole (not shown) of the vehicle body panel. And a joining portion 15. The mounting portion 13 has a check claw 14 cut and raised outward so as to be fixed to the mounting rib 11.
4 are inner wall surfaces 11a, 11 of the mounting ribs 11 facing each other.
In order to cut into a, the taper is reversed in the pulling-out direction to prevent the pull-out.

Further, in the wire harness clip 31 shown in FIGS. 6 and 7, a metal locking member 33 is fixed to a substantially central portion of a mounting board 32 formed in a plate shape using a synthetic resin. Things. The locking lock member 33
Is a pair of holding pieces 35 formed of a pair of vertical walls 35a that are formed by bending a metal plate into a substantially U-shape and a check claw 35b that has the free end of the vertical wall 35a folded further inward. The fixing to the mounting substrate 32 is performed by welding the projection 3 integrally formed at a substantially central portion of the mounting substrate 32.
6 is inserted into a through hole 37 formed in the bottom of the locking member 33, and is heated and swaged.

When the wire harness is fixed to a portion to be mounted such as a body panel, a tape or the like is wound with the wire harness attached to the mounting board 32, and the body panel is sandwiched between a pair of holding pieces 35. Projection piece 8 provided on etc.
By inserting the wire harness clip 31
And the wire harness are integrally fixed to the body panel. In the wire harness clip 31, the interval between the check pawls 35b is made smaller than the thickness of the projection 8 and the tip thereof has a sawtooth shape. The pair of non-return claws 35b are sandwiched, and the non-return claws 35b are made to bite into both side surfaces of the protruding piece 8 to prevent falling off.

[0007]

However, in the case of a resin clip, such as the wire harness clip disclosed in Japanese Utility Model Application Laid-Open No. 58-153525, a synthetic resin having an elastic projection for locking is integrally formed. Therefore, there is a problem in that it is weak in strength and easily broken.
Further, in the clip fixing structure disclosed in Japanese Utility Model Laid-Open Publication No. Sho 61-117908 shown in FIG. 5, if the strength of the resin-made mounting rib 11 is weak, the mounting rib 11 May be damaged. On the other hand, when the strength of the mounting rib 11 is strong, the check claw 14 of the clip 12 bends and cannot be reused.

Further, a wire harness clip 3 having a metal locking member 33 shown in FIGS.
In the case of 1, the locking lock member 33 is
Since the wire harness clip 31 is fixed to the mounting substrate 32 only by external force, stress is concentrated on the welding protrusion 36 when an external force acts on the wire harness clip 31, and the wire projection is easily broken. Further, the locking member 33 for locking is formed by bending a rectangular metal plate, and both side edges have sharp edges.
When the wire harness clip 31 is previously wound around a predetermined position of the wire harness, there is a possibility that another adjacent wire harness may touch the wire harness and break it.

Locked to the panel. Therefore, when these wire harness clips are moved by an external force such as vibration, there is a problem that the external force is directly transmitted to the elastic engaging portion and the engaging portion is elastically deformed, so that the clip easily comes off.

As a wire harness clip that solves the above-mentioned problems, the wire harness clip 1 shown in FIG. 8 winds the locking lock member 4 made of a metal plate and the wire harness 7, It consists of a mounting board 2 made of synthetic resin which holds the lock member 4.
The locking lock member 4 includes a pair of vertical walls 5a and a pair of non-return claws 5b formed in a sawtooth shape so that the free ends of the vertical walls 5a are further folded inward to improve the bite thereof. The holding piece 5 is provided. On the vertical wall 5a,
An engagement hole 4a is formed to engage with the locking projection 3c provided on the mounting substrate 2.

A pair of protective walls 3 are provided upright along the outer surface of the holding piece 5 on the mounting substrate 2 on which the wire harness 7 is wound and fixed by a tape 6 or the like. The lower side of the inner side of the wall 3 is open so that the locking member 4 can be pushed in from below. On the upper edge of the protection wall 3, a locking flange 3 b set to a size to cover the bent upper end of the locking lock member 4 is formed. When the stop lock member 4 is pushed in, slip-through prevention and positioning are performed. On the inner wall surface of the side wall 3a, a locking projection 3 that engages with the engagement hole 4a.
c is formed, and the lower surface of the locking projection 3c is formed in a slanted shape, so that when the locking lock member 4 is pushed in from below, it is smoothly inserted into both vertical walls 5a of the locking lock member 4. Get on and push in smoothly.

However, when it is necessary to remove the locking projection 3c from the wire harness for maintenance or the like, if the strength of the locking projection 3c is not sufficient, it is necessary to carefully perform the removal operation, and improvement in workability is desired. .

An object of the present invention has been made in view of the above problems, and has as its object to provide a clip for a wire harness which allows a wire harness to be removed without damaging the components of the clip.
