【Example】

 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. The clamp 10 of the wire harness of the present invention comprises a first clamp member 11 and a second clamp member 12 made of synthetic resin.

As shown in FIGS. 1 and 2, the first clamp member 11 is provided with a rectangular substrate 11 a, and a step portion is provided at the tip on the lower surface of one end side (right side in the figure) of the substrate 11 a in the longitudinal direction. The arrow-shaped clip portion 11b provided with 11b-1 is integrally formed. Further, on the upper surface of the substrate 11a, a square-shaped shaft portion 11c is projected coaxially with the clip portion 11b, and a large-diameter head portion 11d continuous with the tip end surface of the shaft portion 11c is integrally formed. Molded. The protruding length of the shaft portion 11c is set to be substantially the same as the thickness of the second clamp member 12.

The second clamp member 12 is provided with a rectangular substrate 12 a, and a regular square hole fitted to the shaft portion 11 c of the first clamp member 11 at one end side (left side in the figure) of the substrate 12 a. The portion 12b is provided. Further, a notch 12c which is continuous from the hole 12b to the one end side of the substrate 12a and which can be inserted from the side of the shaft 11c is integrally formed, and the hole 12b of the notch 12c is also formed. A locking projection 12d is provided so as to face each other at a position continuous with. As shown in FIG. 3A, the gap between the facing protrusions 12d for locking is set to be smaller than the length L of one side of the shaft portion 11c of the first clamp member 11.

When the wire harness is fixed straight, the clamp 10 having the above-described structure is configured such that the second clamp member 12 is linearly opposed to the first clamp member 11 as shown in FIG. 3 (A). The notch 12c is inserted into the shaft portion 11c while the locking protrusion 12d is widened by a strong force in the direction indicated by the arrow A, and the hole portion 12b is externally fitted and fixed to the shaft portion 11c.

In the fitted state, the shaft portion 11c of the first clamp material 11 and the hole portion 12b of the second clamp material 12 have a corresponding square shape, so that the first clamp material 11 and the second clamp material 12 are in contact with each other. 12, the respective sides of the shaft portion 11c are in contact with the respective sides of the hole portion 12b so as to face each other and are prevented from rotating, so that the clamp members 11 and 12 are held straight. Moreover, since the gap between the locking protrusions 12d of the second clamp member 12 is smaller than one side of the shaft portion 11c of the first clamp member 11, even if tension is applied to the wire harness from the outside, The second clamp member 12 never separates from the first clamp member 11.

Then, similarly to the conventional example shown in FIG. 8, the wire harness 2 is arranged on the upper surface of the clamp 10, and both ends of the clamp 10, that is, the first clamp member 11 and the second clamp member 12 are not connected. On the end side, the wire harness 2 is wound together with the substrates 11a and 12a with the adhesive tape 5 and fixed to the clamp 10. Then, as shown in FIG. 4, the clip portion 11b of the first clamp member 11 is inserted into the clip hole 13a of the vehicle body panel 13, and the step portion 11b-1 at the tip of the clip portion 11b is attached to the periphery of the clip hole 13a. Engage and secure.

On the other hand, when the wire harness 2 is bent and fixed in an L-shape, as shown in FIG. 3 (B), the second clamp member 12 is made to face the first clamp member 11 at a right angle, When the notch 12c is inserted into the shaft 11c with a strong force in the direction indicated by the arrow B, the hole 12b fits into the shaft 11c, and both clamps 11 and 12 are L-shaped in the same manner as above. The wire harness 2 may be held and fixed on both substrates 11a and 12a of the clamp 10 by winding the tape with the adhesive tape 5.

In the clamp 10, the second clamp member 12 is provided with the notch 12c continuous with the hole 12b so that both clamp members 11 and 12 are fixed in a straight line shape or a rectangular shape. In this state, the second clamp material 12 can be forcibly rotated with respect to the first clamp material 11. Therefore, after the wire harness 2 is attached, it is possible to adapt it to the shape of the attachment location of the vehicle or the like.

Further, in the above embodiment, the shaft portion 11c and the head portion 11d are integrally formed on the upper surface of the substrate 11a of the first clamp material 11, but as shown in FIG. The shaft portion 11c, the head portion 11d, and the clip portion 11b may be coaxially and integrally formed on the lower surface.

Furthermore, in the above embodiment, the shaft portion 11c of the first clamp member 11 and the hole portion 12b of the second clamp member 12 have a quadrangular shape, but as shown in FIGS. 6 (A) and 6 (B). If a regular pentagonal shape or regular hexagonal shape is used, the second clamp member 12 can be selected at 72 ° intervals or 60 ° intervals other than the right angle (90 °) with respect to the first clamp member 11 at the required angle. Can be installed. For example, as shown in FIG. 7, in the case of a regular hexagonal shape, the wire harness 2 can be bent and fixed at a required angle (30 degrees in the figure). If the shaft portion 11c of the first clamp member 11 and the hole portion 12b of the second clamp member 12 have a more polygonal shape, the wire harness 2 can be bent and fixed at a more desired angle.
