Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attachment device for a wire harness attached to a flange portion of a panel, etc.

[Prior Art] In order to attach a wire harness that bundles a large number of wires to a flange at the end of a panel, a clamp is attached to the flange and the wire harness is attached to this. As disclosed in Japanese Utility Model Publication No. 55-54091, the clamp has a plug-in connection part for attaching a wire harness holding clip to the opposing planes of a groove-shaped band made of elastic material having inwardly protruding claws. A clamp that is inserted into the flange, or a plastic holder with a locking piece and a metal spring clip for panel mounting, as disclosed in Japanese Utility Model Application Publication No. 60-66219, can be used to attach the flange to the flange. There are known clamps that can be inserted into.

In addition, as in the wire harness clamp device disclosed in Japanese Utility Model Publication No. 57-30535, a triangular locking hole is provided in the L-shaped bracket, and a flexible locking plate protruding into the hollow case that is pushed into the bracket slides. A tab that engages with the locking hole is provided on the bottom of the curved surface, and a release tongue is provided that connects to the tab. When this hollow case is pushed into the bracket, the smooth curved surface of the bottom slides over the edge of the locking hole. A device is known in which the tab is inserted into the triangular locking hole and engaged with the triangular locking hole.

[Problem to be solved by the invention] Since the conventional clamp as described above is configured to be attached by inserting a clip into the flange, some workers may notice that the clip does not fit properly. There were variations in the insertion state, and if the insertion state was not fully inserted and it was slightly locked on the flange part, there was a risk that it would come off due to vibration etc. For this reason, it is necessary to confirm whether or not it is inserted securely, but conventionally this has been determined by visual inspection, which poses the problem that confirmation cannot be done when working on a line where there is not enough time.

Furthermore, in the wire harness clamp device of Utility Model Publication No. 57-30535, a slight insertion shock occurs at the moment the hollow case is pushed into the bracket and the claws of the flexible lock plate are inserted into the triangular locking holes of the bracket. Even if there is, this is because the tab smoothly fits into the locking hole without any resistance while the smooth curved surface of the bottom slides on the edge of the locking hole, causing the tab to undergo large deformation and make a loud shock sound. The shock is not strong enough to cause a shock, and even if there is a slight shock noise, this faint shock sound is difficult to hear in a noisy environment such as a factory, so it is safe to insert it in a noisy factory assembly site. It is not possible to confirm whether this is the case by listening to the shot sound.

The present invention solves the above-mentioned problems and makes it possible to easily and reliably check whether the wire harness is inserted securely without relying on visual inspection as in the past. It is an object of the present invention to provide a wire harness attachment device that can be reliably attached to a flange portion.

[Means for Solving the Problems] For the above-mentioned purpose, the present invention provides a tip face recess 12b in a Y-shaped tip 12a on the inner inner surface of one side plate portion 2 of the plastic inverted U-shaped clamp 1. A Y-shaped bullet sound notification piece 12 with a shape formed therein is provided in a protruding manner, and a flexible plate-shaped bullet sound notification piece 13 is provided in a protruding manner on the inner inner surface of the other side plate portion 3.
The wire harness attachment device is constructed by arranging the tips of the wire harnesses so as to face each other vertically.

[Function] When the panel flange is fully inserted into the inner end of the plastic inverted U-shaped clamp 1, the Y-shaped elastic sound notification piece 12 is activated by the flange end inserted into the inner end. Y-shaped tip 12
a is pushed upward, and the tip 13b of the flexible plate-shaped resilient sound alarm piece 13 above it is also pushed up against the elasticity of the plastic piece, and the corner edge 13 of this tip 13a forms the other Y-shape. Bullet repellent sound notification piece 1
It instantly fits into the recess 12b of the Y-shaped end 12a of No. 2 due to its elasticity. This upper tip 13a
is the tip surface concave portion 12b of the lower Y-shaped tip portion 12a.
When it is instantaneously inserted into the Y-shaped tip 12a, the tip 13a elastically hits the tip surface recess 12b of the Y-shaped tip 12a, producing a repelling sound.

The Y-shaped repellent sound notification piece 12 has a Y-shaped tip 1.
2a is formed in a Y-shape, and further includes a concave portion 12 on the tip surface.
b is formed, and the Y of this Y-shaped repellent sound notification piece 12
The letter-shaped tip 12a and the tip 13a of the flexible plate-shaped elastic sound notification piece 13 bend strongly against the elasticity of the plastic when the panel flange is pushed up, so that they can fit into the concave portion 12b of the Y-shaped elastic sound notification piece 12. The tip corner edge 13b of the flexible plate-shaped bullet-repelling sound notification piece 13 is elastically fitted and the repelling sound emitted when struck is loud and can be easily heard even in a noisy environment such as in a factory. It makes a loud noise.

When this repelling sound occurs, the panel flange is located at the innermost Y-shaped tip 12 inside the U-shaped clamping clamp 1.
This is when the panel flange has been fully inserted to the position where a is pushed up, so the operator can confirm that the panel flange has been securely inserted to the rear end by hearing this repelling sound.

[Example] An example of the present invention will be described with reference to the drawings. Figures 1, 2 and 3 are the front view of the inverted U-shaped clamp in the wire harness clamp of the present invention;
The end face and cross-section taken along the lines of FIG. 1 are shown, and FIGS. 5, 6 and 7 show the spring clip installed within the U-shaped clamp.

First, in FIGS. 1, 2, and 3, 1 is a clamp made of plastic in an inverted U shape, 2 and 3 are side plate parts thereof, and 4 and 5 are both side plate parts 2 and 3. The opening edge is formed by bending the lower end into a hook shape. 6 and 7 are these side plate parts 2 and 3
This is a panel flange clamping protrusion protruding toward one side of the middle part of the inner surface of the panel flange, and numerals 8 and 9 are protrusions provided below the panel flange clamping protrusions 6 and 7 for engaging the side edges of the spring clip. Said both side plate parts 2 and 3
The gap between the lower opening edges 4 and 5 forms an opening into which the flange of the panel is inserted, and the gap between this opening gap and the panel flange holding protrusions 6 and 7 is as shown in FIG. A panel flange insertion path 10 is formed as shown by the chain line in FIG. Reference numeral 11 designates a wire harness mounting plate portion in the form of a horizontally long strip that is integrally provided on the outer surface of one of the side plate portions 2 .

On the inner surfaces of both side plate parts 2 and 3 at the innermost part of the above-mentioned inverted U-shaped clamp 1, one side plate part 2 is provided as a member for audibly announcing the insertion and insertion of a panel flange.
A Y-shaped repulsion sound notification piece 12 is provided protruding from the inner inner surface of the side plate 3, and a flexible plate-shaped repulsion sound notification piece 13 is provided protruding from the inner inner surface of the other side plate portion 3. The tip of this Y-shaped repellent sound notification piece 12 is formed into a Y-shape and has a Y-shaped tip 12a, and a tip surface recess 12 is provided in the Y-shaped tip 12a.
form b. Further, the tip portion 13a of the flexible plate-shaped rebound sound notification piece 13 is positioned above the Y-shaped tip portion 12a of the Y-shaped rebound sound notification piece 12.

In the inverted U-shaped clamp 1, as shown in the fourth figure, when the flange portion of the panel is inserted into the inner end of the panel flange insertion path 10 indicated by the chain line, the Y-shaped repulsive sound notification piece 12 The tip end portion 12a of the shape is pushed up by the upper end of the flange portion and is bent upward from the dotted line position to the solid line position and is pushed up against the elasticity of the plastic piece.

When the Y-shaped tip 12a is pushed upward in this way, the tip 13a of the flexible plate-shaped repelling sound alarm piece 13 above it is also pushed up as shown by the dotted line against the elasticity, and the next moment this push-up occurs. The corner edge 13b of the distal end portion 13a that has been formed is the concave portion 12b of the distal end surface of the Y-shaped distal end portion 12a of the Y-shaped repulsive sound notification piece 12.
It snaps into place instantly with its elasticity.

In this way, the tip corner edge 13b of the flexible plate-shaped elastic sound notification piece 13 is elastically fitted into the tip surface recess 12b of the other Y-shaped elastic sound notification piece 12, and the Y-shaped elastic sound notification piece 13 is fitted into the tip surface recess 12a. When the lower piece of 12b is struck elastically, a repellent sound is generated.
This means that the Y-shaped tip 12a at the innermost end is fully inserted to the position where it is pushed up.

Y-shaped tip 12a of Y-shaped repellent sound notification piece 12
The tip 13a of the flexible plate-shaped bulletproof sound notification piece 13 bends strongly against the elasticity of the plastic when the panel flange is pushed up, so that the Y-shaped bulletproof sound notification piece 1
