At this time, the wire harness is pinched in a meandering state by being pressed by the upper and lower pressing protrusions.

The slit of the pressing plate allows the ridge of the pressing plate to be flexibly deformed (elastically deformed). Further, the slit of the substrate allows the ridge of the substrate to be flexibly deformed. That is, since the ridges of the pressing plate or the substrate are separated from the pressing plate or the substrate at the slit, when the wire harness is sandwiched between the substrate and the pressing plate, it can be flexibly deformed in the vertical direction, and the outer diameter of the wire harness can be changed. Allows for a difference and helps in good clamping.

(Embodiment) Next, a first embodiment of the present invention will be described with reference to FIGS.

The wire harness fixing clip 10 is integrally molded using a synthetic resin material, and includes a support portion 11 for attachment to the body side and a holding portion 13 for fixing the wire harness 12.

As shown in FIG. 1 or 5, the support portion 11 includes a seal body 14 formed in a downward circular dish shape, and a leg portion 15 protruding downward from the center of the lower surface of the seal plate 14. There is. Then, a pair of claws 16 having a predetermined shape that is opened in a bifurcated shape is projected obliquely upward from the lower end of the leg portion 15.
The claw 16 has a thickness such that it can be flexibly deformed.

A rectangular flat plate-shaped substrate 17 is provided on the upper surface side of the seal plate 14. A pair of fixing ridges 18 are formed in the front-rear direction on both sides of the upper surface of the substrate 17, so that the substrate 17 has a concave shape as a whole as shown in FIGS. 4 and 5. It has a cross-sectional shape. Then, as shown in FIGS. 1 and 3, the front end of the protrusion 18 projects slightly to the front of the substrate 17, and is a locking portion 19 having a downward step at this portion. . Further, an inclined guide surface 20 is formed on the upper portion of the locking portion 19.

From the rear end side of the board 17, to the predetermined height set corresponding to the thickness of the wire harness 12, the connecting wall portion 21.
Is erected, and a rectangular flat plate-like pressing plate 23 having a vertical width substantially the same as the front-back width of the substrate 17 is integrally formed from the top of the wall portion 21 via a thin-walled portion 22 functioning as a hinge. Has been formed.

A ridge 24 having a mountain-shaped cross section, in this example, a gentle mountain shape, is formed along the center of the front side surface of the pressing plate 23 at a position alternating with the ridge 18. Therefore, the pressing plate 23 is As shown in the figure, it has a convex sectional shape as a whole. That is, the ridges 1 that alternately project toward the opposing surfaces of the board 17 and the pressing plate 23 along the longitudinal direction of the wire harness to be fixed and appropriately press the wire harness.
8, 24 are provided.

As shown in FIG. 1, FIG. 2 and FIG.
Slits 29 having substantially the same length as the ridges 24 are formed along both sides of the ridges 24 provided in the No. 3 structure. Therefore, the ridge 24
Is integrated with the pressing plate 23 only at both ends in the longitudinal direction. Then, the entire pressing plate 23, or at least a portion continuous with the ridge 24, is formed to have a thickness capable of being flexibly deformed. Therefore, when the wire harness is clamped, the ridge 24 of the pressing plate 23 is likely to be flexibly displaced in the direction of the arrow in FIG. Therefore, a wire harness (not shown)
It can handle variations in thickness.

Further, as shown in FIGS. 1 and 3, a hook wall portion 25 having a width substantially the same as that of the wall portion 21 projects forward from the top of the pressing plate 23, and this wall portion 25 is provided. An inwardly bent hook 26 is provided along the tip of the.

The present embodiment is configured as described above and is used as follows.

First, when the wire harness 12 is held by the clip 10, the wire harness 12 is placed sideways on the substrate 17 as shown in FIG.
Push forward in the direction to close it. Then, as shown in FIG. 2, the board 17, the wall portion 21, the pressing plate 23, and the wall portion 25 form a rectangular tubular body, and the wire harness 12 is inserted through the inside thereof. When the hook 26 at the tip of the wall 25 comes into contact with the locking portion 19, the wall 25 is pushed further downward, and the hook 26 descends along the guide surface 20 with elastic deformation of the wall 25 and the like. And engages with the locking portion 19.

At this time, the wire harness 1 is provided between the substrate 17 having the protrusions 18 protruding and the pressing plate 23 having the protrusions 24 protruding.
Since 2 is held in a meandering shape as shown by the phantom line in FIG. 5, sufficient holding force is exerted even in a weak pinching state where the wire harness 12 is slightly dipped as shown in FIG. Obtainable. The ridge 24 of the pressing plate 23 is provided with slits 29 on both sides thereof and has an appropriate flexibility.

Further, since the ridge 24 on the pressing plate 23 side is projected in a gentle mountain shape, the wire harness 12 is kept in a gentle meandering state. From the above points, an excessive clamping force or bending action is not applied to the wire harness 12, which is advantageous in preventing disconnection of the electric wires forming the wire harness 12.

In addition, since the ridge 24 of the pressing plate 23 has an appropriate flexibility, it is possible to allow the outer diameter difference of the wire harness 12 and to satisfactorily clamp the wire harness 12.

In addition, as described above, the wire harness 1 using the clip 10 can be obtained simply by tilting the pressing plate 23 forward and engaging it with the board 17 side.
Since 2 is held, the work is simple and quick.

Further, if necessary, the hook 26 can be removed from the engaging portion 19 and the wire harness 12 can be released from the clip 10 simply and quickly.

Then, as shown in FIG. 5, in the same manner as the conventional example,
The support portion 11 is press-fitted into the mounting hole 28 of the body 27 to fix the wire harness 12 to the body side.

In the above embodiment, as shown in FIGS. 6 (a) to 5 (f), the cross-sectional shapes of the protrusion 18a provided on the substrate 17a side and the protrusion 24a provided on the pressing plate 23a side are different from each other. Various modifications are possible, and even if the top surfaces 18b, 24b of the ridges 18a, 24a are formed into fine irregularities or rough surfaces, the frictional resistance with the wire harness is increased. good.

Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8.

In this embodiment, slits 30 are formed along the bases of the pair of protrusions 18 provided on the substrate 17. The slit 30 has a function of giving elasticity to the ridge 18. That is, since the top surface of the protrusion 18 is thin, it is easily bent and deformed in the direction of the arrow in FIG. Therefore, it is possible to cope with variations in the thickness of the wire harness (not shown).

The configuration and operation of the other points in this embodiment are similar to those of the first embodiment.

(Advantages of the Invention) The wire harness fixing clip of the present invention can easily, quickly, and easily attach the wire harness to the body side without using a separate member.

Further, since the clip of the present invention has a structure in which the protruding ridges for alternately protruding along the longitudinal direction of the wire harness are provided on the opposing surfaces of the board and the pressing plate, the wire harness meanders between the board and the pressing plate. The wire harness can be pinched in a fixed shape, and the wire harness can be fixed well.

The pressing plate or the slit of the substrate according to the present invention allows the pressing ridge of the pressing plate or the substrate to be flexibly deformable, thereby allowing the outer diameter difference of the wire harness and properly sandwiching the wire harness. .
