[0003]

[Problems to be solved by the device]

 However, the above-described conventional wire harness clamp has the following problems. That is, in the case of the band clamp system, the workability of attaching the wire harness 23 to the pipe 21 is poor, and if the tightening force of the band clamp 22 is difficult and too weak, the vehicle is There is a problem that the wire harness 23 is displaced around the pipe 21 due to vibration and the route of the wire harness 23 varies. Further, in the case of the resin elastic clamp method, in the method of fixing to one pipe 21, the wire harness 23 may be displaced together with the clamp around the pipe 21 after mounting, so that it is different from the case of the band clamp. Similarly, there is a problem that the route of the wire harness 23 varies, and since the fixing method is so-called catching method in both one and two methods, the holding property of the clamp 24 in the pulling direction is unsatisfactory. There is a problem in that.

In view of the above problems, the present invention has a good workability in that it can be fixed with a reliable holding force between two members having a circular cross section as an attached portion and can be attached by one-touch work. Providing clamps for wire harnesses is a technical issue to be solved.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is configured as follows. That is, a clamp for a wire harness that includes a clamp part that holds the wire harness, and a clip part that is integrally formed with the clamp part and that is inserted and fixed between two members having a circular cross section as an attached part. The clip portion has a pair of substantially arcuate insertion leg pieces that can be inserted so as to wrap around the opposing peripheral surface between the two members, and the clip portion is inserted between the insertion leg pieces. The insertion leg piece is inserted so as to wrap around the outer peripheral surface of the two members while being engaged with the leg piece, and when the insertion leg piece wraps between the two members, the insertion leg piece is relatively opposed to the insertion leg piece. A locking member that locks immovably is provided.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 shows a free state immediately before mounting the wire harness clamp, and FIG. 2 shows a fixed state in which the wire harness clamp is mounted between two pipes, which are mounted portions. The wire harness clamp 1 according to the present embodiment is a resin integrally molded product made of polypropylene or the like, for example, and has a clamp portion 2 for holding the wire harness 14 so as to hold it, and a circular cross section as an attached portion. Between the two members, specifically, the clip portion 3 which is inserted and fixed between two parallel metal pipes 15 as air conditioner pipes in the engine room of the vehicle.

The clamp part 2 includes a pair of semi-annular grip pieces 5 joined to each other by an integral hinge 4, and an abutment piece 6 that joins the grip pieces 5 to each other at a substantially central portion on the back side thereof. As shown in FIG. 1, both of the holding pieces 5 are always held in an expanded state.

Then, if the wire harness 14 to be grasped is inserted between both holding pieces 5 and pressed against the integral hinge 4 as shown by an arrow in the figure, both holding pieces 5 will be moved as shown by phantom lines in FIG. It is rotated in the closing direction around the integral hinge 4 and grips the wire harness 14 so as to hold it. When the connecting part of both gripping pieces 5 with the integral hinge 4 passes through the connecting part with the abutment piece 6, a force in the closing direction acts on both gripping pieces 5 to positively grip the wire harness 14. In addition, this gripping state is held by the claws 5a provided at the tips of both gripping pieces 5 biting each other.

On the other hand, the clip portion 3 is fixed to the pipes 15 by being inserted between the pipes 15, and a pair of insertion leg pieces 7 made of substantially rectangular plates facing each other with a constant interval. And a locking member 8 which is located between both insertion leg pieces 7 and which is inserted between the pipes 15 and which is a substantially wedge-shaped block for preventing the insertion leg pieces 7 from coming off after insertion. The clip portion 3 is integrated with the clamp portion 2 by connecting the base end portion of one insertion leg piece 7 to one end of the abutment piece 6 of the clamp portion 2 via a connecting piece 9. .

Therefore, the pair of insertion leg pieces 7 are formed in a substantially arc shape so as to be able to wrap around along the peripheral surfaces of both pipes 15 in an engaged state when inserted between the opposing pipes 15. In the normal state, the distal end side (insertion side) is positioned so as to have a narrow, substantially V shape. The distance between the outer surfaces of the distal ends of both insertion leg pieces 7 is set to be substantially the same as the distance between the narrowest portions of the peripheral surfaces of both pipes 15. Further, ribs 12 project from both sides in the width direction on the outer surface (back surface) side of the insertion leg piece 7 and on the tip side and the base side. Therefore, since the rib 12 actually engages with the peripheral surface of the pipe 15, the outer surface side including the rib 12 which is the engagement surface with the peripheral surface of the pipe 15 is formed to have a shape that is closest to a circular arc. ing.

The tip ends of the pair of insertion leg pieces 7 are connected to each other by the elastically deformable thin piece 10, and both the insertion leg pieces 7 and the locking portions 8 are on the base end side thereof. They are connected to each other by a thin piece 11 which is elastically deformable. The tip-side thin-walled piece 10 is normally in a substantially U-shaped curved shape, while the base-side thin-walled piece 11 is in a generally linear shape.

On the other hand, the locking member 8 for pushing the insertion leg pieces 7 between the pipes 15 by pushing them between the insertion leg pieces 7 has a flat surface suitable for pushing at the base end thereof. The pressing portion 8c is formed, and the tip portion thereof is provided with an engaging portion 8a capable of contacting a stepped shoulder portion 7a formed on the inner surface side of the tip portion of both insertion leg pieces 7. . Further, substantially serrated locking teeth 7b are formed on the inner surface of the insertion leg piece 7, and correspondingly serrated locking teeth 8b are formed on the outer surface of the locking member 8 correspondingly. Then, when the insertion teeth 7b and 8b are inserted between the pipes 15, the insertion legs 7 and the engagement portion 8 are engaged with each other so as to be relatively immovable. A substantially triangular cavity 13 is set in the center of the locking portion 8.

Next, the work of mounting the wire harness 14 by the wire harness clamp 1 according to the present embodiment configured as described above will be described. First, when the wire harness 14 to be attached is pushed between the pair of gripping pieces 5 in the expanded state of the clamp part 2, both gripping pieces 5 rotate about the integral hinge 4 as shown by a virtual line in FIG. While displacing to the abutment piece 6 side. As a result, the wire harness 14 is gripped by both gripping pieces 5, and the claws 5a of both gripping pieces 5 bite to hold the gripped state.

Next, the rib 12 on the rear surface of the distal end portion of the insertion leg piece 7 in the clip portion 3 is formed approximately in the middle between the outer peripheral surfaces of the pipes 15 as the air conditioner pipes which are parallel to each other as shown in phantom in FIG. Insert up to and engage. In this state, when pushing force is applied to the pressing portion 8c of the locking member 8 in the direction of the arrow, the engaging portion 8a of the locking member 8 engages with the shoulder portion 7a of both insertion leg pieces 7. In order to press this, the insertion leg piece 7 is inserted between both pipes 15 together with the locking member 8.

At the time of this insertion, both insertion leg pieces 7 receive a pressing force inward by the pipe 15 on the base side, but the tip side after passing through the narrowest part between the pipes 15 is released from being restrained by the pipe 15. Will be. That is, the insertion leg piece 7 is inserted while being displaced so that the base side approaches and the tip side moves away, and as a result, the insertion leg piece 7 is inserted so as to wrap around the peripheral surface of the pipe 15. Therefore, the shoulders 7a of the two insertion leg pieces 7 are separated from the engagement portions 8a of the locking member 8, but the locking teeth 7b of the insertion leg pieces 7 are sequentially attached to the locking teeth 8b of the locking member 8 from the tip side. Bite and finally the condition shown in Fig. 2 is reached.

That is, both insertion leg pieces 7 are engaged with the opposing outer peripheral surface of the pipe 15 so as to be wound around, and in this engagement state, the locking member 8 is engaged with the insertion leg piece 7 in a wedge shape. , The relative movement becomes impossible. In this way, the clip portion 3 mounted between the two pipes 15 is prevented from rotating with respect to the pipe 15 and its movement in the inserting / removing direction is fixed, and the axial direction of the pipe 15 is also engaged with the pipe 15. The movement of the surface is fixed by the frictional force of the surface. Thus, the clip portion 3 is securely fixed to the pipe 15 in any direction. It should be noted that the thin pieces 10 and 11 respond to the expansion of the distal end side of both insertion leg pieces 7 and the contraction and closure of the base side by elastic deformation.

As described above, the wire harness clamp 1 according to the present embodiment can be easily performed by a one-touch operation in which the locking member 8 is pushed in while the tips of the insertion leg pieces 7 are pressed between the pipes 15. Not only can it be mounted, but it can be securely fixed in the pushed-in position with a strong holding force.

In this embodiment, the pipe 15 for the air conditioner has been described as an attached part of the wire harness clamp 1, but the present invention is not limited to this, and the cross-sectional shape is substantially circular. When the two members forming the above are present at regular intervals, they can serve as attached parts. The rib 12 may be omitted.

[0020]

[Effect of device]

 As described in detail above, according to the wire harness clamp of the present invention, it can be fixed to the mounted portion with a reliable holding force, and can be mounted by one-touch work, so that it is affected by vehicle vibration and the like. It is possible to hold the wire harness in the specified position without having to do so and to improve the work efficiency for mounting.
