Description

[Detailed Description of the Invention] This invention relates to a clamp for wire harnesses and the like used for electrical wiring and piping in automobiles and the like.

Conventionally, when wiring a wire harness, etc., the wiring was done by screwing, for example, a cowl outer flange, etc., through a clamp formed from a metal plate, etc.
This method of attachment was extremely laborious and inefficient in attaching the clamp to the flange.

For this reason, a composite clamp made of synthetic resin and spring steel has been developed and can be attached to the cowl outer flange extremely easily, but this composite clamp is expensive to manufacture. There were drawbacks.

Therefore, the clamp aha' shown in FIGS. 4 and 5 was integrally formed from synthetic resin, but when the clamp a shown in FIG. When external force F acts on clamp a, clamp a is displaced and elastically deformed around point P at the tip of its upper hanging piece, and as a result, the locking piece C integrally formed on the upper hanging piece is also largely displaced. There is a drawback that the engagement with the edge piece of the cowl outer flange f tends to come off easily.In addition, in the case of the clamp a' shown in Fig. 5, in order to prevent the engagement of the engagement piece C from coming off, Although the leg piece d was attached as shown in the figure, there was a drawback that a large amount of force was required to attach it to the cowl outer flange f in case of stiffness.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a clamp for wire harnesses, etc., which has excellent hanging power and can perform hanging operations quickly and easily.

Next, one embodiment of the present invention will be explained according to the drawings.
FIG. 1 shows an abbreviated flange 1 (hereinafter simply referred to as flange), such as a cowl outer flange.

) along which a wire harness 2 and a washer hose 3 are removably disposed via a plurality of clamps 4.

Reference numeral 4 indicates the entire clamp described above, and this clamp 4 is molded from synthetic resin or the like.

Reference numeral 6 denotes a side piece of the clamp 4, which is attached almost perpendicularly to the flange 1, and a support piece 7 extending toward the lower surface of the flange 1 is formed at the lower end of the piece 6. The side piece 6 and the support piece 7 form a main body 5 with a blurred cross section.
A force bone portion 8 is integrally formed approximately at the center of the outer surface of the holder.

Reference numeral 9 denotes a guide piece for the clamp 4, which is formed horizontally from a part of the side piece 6 along the upper surface of the flange 1 with a slightly shorter projecting width than the above-mentioned support piece 7. A gripping piece 10 having elasticity is formed upwardly on the guide piece 9, and a gripping groove 11 in which the wire harness 2 is removably fitted is formed on the upper surface side of the guide piece 9 by the side piece 6 and the gripping piece 10. It is formed.

In addition, a curved small grip piece 12 which is given elasticity in the same way as the grip piece 10 is integrally attached to a part of the outer surface of the grip piece 10. A groove 14 is formed.

Furthermore, a groove 15 is recessed in the base of the guide piece 9 described above along the width direction T of the clamp 4.

Reference numeral 16 denotes an upper formwork that extends upward from the edge of the support piece 7 and comes into contact with the lower surface of the flange 1;
On the right side surface of the guide piece 6 in the drawing, there is a locking piece that extends horizontally from the lower surface of the guide piece 9 at a predetermined interval through a thin part 17 and is further bent so that its tip approaches the vicinity of the base of the guide piece 9. 1
8 is formed, and this locking piece 18 is formed to be extremely elastically displaceable via the thin wall portion 17.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, in the clamp 4 of this example, the locking piece 18 is provided so as to be elastically displaceable with respect to the upper formwork 16 via the thin wall portion 17, so that the edge piece 1A of the flange 1 can be moved between the guide piece 9 and the locking piece 18. When the locking piece 1 is inserted between the
8 is extremely easily pivoted downward around the thin wall portion 17.

Therefore, even when pushing the side piece 6, the pushing resistance due to the edge piece 1A is significantly reduced, which is advantageous because the hanging operation can be done quickly and easily with a small force.

Furthermore, even if the clamp 4 is elastically deformed and displaced about the point P as shown in the figure due to the external force F working in the direction of unlatching the tough lamp 4 from the flange 1, the thin wall portion 1
The component force of this external force F exerted on the attached locking piece 18 via the clamp 7 is significantly reduced, and the locking piece 18 maintains the locked posture with the edge piece 1A, so that the flange 1 of the clamp 4 It has many features such as improved hanging power.

Now, the present invention is a clamp for hooking a wire harness or the like to an abbreviated flange, and the clamp extends from the lower end of the side piece that is substantially perpendicular to the edge of the abbreviated flange. A cross section consisting of a support piece extending to the lower surface side of the oval-shaped flange integrally forms a shaggy-shaped main body, and a part of the side piece has a support piece extending to the upper surface of the oval-shaped flange. a holding piece is provided upwardly from the edge of the guide piece, and an upper formwork is provided on the edge of the support piece to abut the lower surface of the abbreviated flange; Since this clamp has a structure in which a locking piece is provided in a part of the upper formwork through a thin wall part along the abbreviated flange and elastically abuts and engages with the edge piece of the flange, it is possible to Harnesses, etc. can be removably fitted and hooked onto the oval-shaped flange extremely easily and quickly with a small pushing force, and the hooking force is excellent, making it extremely practical as a clamp for wire harnesses, etc. This is a new idea.
