For this reason, the grip part which couple | bonds a wire harness is provided in the lower surface of the lock part, ie, the lower clamping piece side. As a result, the clamping piece on the lower side of the lock portion is deformed so as to bend downward due to the weight or vibration of the wire harness, and the lock portion is detached from the rib, so that the temporary fixing function of the wire harness cannot be performed.

  The present invention is intended to solve such a problem, the purpose of the wire harness is provided on the holding piece side below the lock portion, the lock portion is difficult to come off, It is an object of the present invention to provide a temporary clamping clamp that can appropriately maintain a temporary fixing state of a wire harness.

The present invention is for achieving the above object, and is configured as follows.
The first invention is a temporary fastening clamp for temporarily fastening the free end portion of the wire harness to the attached member until the attached member to which the wire harness is wired is attached to the mating member. And a lock portion that is attachable to and detachable from the temporary fastening rib formed on the mounted member, and a grip portion that can be coupled to the free end portion of the wire harness . Lock portion engages in a state where the held upper and lower pair of holding pieces in this rib by insertion into the rib from the upper and lower both sides, and, among the pair of upper and lower holding pieces, which can engage the rib The lower holding piece provided with the engagement protrusion is bent downward to be disengaged and can be pulled out from the rib. The gripping portion is located on both sides of the lower holding piece in the lock portion and is connected to the lock portion in a cantilever manner together with the lower holding piece, while the lower holding pin is held by the slit. The pieces are separated from each other and can be flexed and deformed independently, and a free end portion of the wire harness is coupled to the lower surface portion thereof.

According to this configuration, the engagement portion that can be engaged with the rib is provided on the lower holding piece for the reason that a sufficient space cannot be secured on the upper side of the rib of the mounted member , and the lock portion is mounted. It is configured to engage with the rib of the member so that it does not easily come off, and to be pulled out from the rib by bending the lower holding piece downward , and the gripping part of the lower holding piece in the lock part Provided on both sides, the free end of the wire harness is coupled to the lower surface of the gripping portion. Nevertheless, the gripping part is supported in a cantilevered manner with respect to the lock part together with the lower clamping piece, so that it can be flexed and deformed independently from the lower clamping piece by the slit. Therefore, it is possible to prevent the weight or vibration of the wire harness from acting on the holding piece below the lock portion. Therefore, it is possible to eliminate the deformation of the holding piece on the lower side of the lock portion, the lock portion is less likely to be detached from the rib of the mounted member, and the temporary fastening state of the wire harness can be appropriately maintained.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
Figure 1 is an explanatory diagram showing a use state of the clamping temporary Fasten. The rear bumper 10 shown in this drawing corresponds to the “mounted member” of the present invention, and the vehicle body 20 corresponds to the “mate member” of the present invention. Rear bumper 10 is provided with a rib 12 capable of mounting the clamp 30 for temporary Fasten the top of the inside.

Inside the rear bumper 10, a wire harness 16 of pack sonar and corner sonar is wired. The free end 16a of the wire harness 16, i.e. clamp 30 for temporary Fasten the end with a connector 18 is coupled. In the body 20, the wire harness 22 wired to the portion covered by the rear bumper 10 has a connector 24 that can be connected to the connector 18 of the wire harness 16.

Figure 2 is a perspective view showing a clamping temporary Fasten. Figure 3 is a side view showing the clamping temporary Fasten. 4 is a cross-sectional view in the direction of arrow AA in FIG. Clamp 30 for apparent provisionally Fasten from these drawings, a detachable locking unit 32 relative to the ribs 12 of the rear bumper 10, coupling the free end portion 16a having a connector 18 of the wire harness 16 It is possible to provide a grip portion 40 that can

  The lock portion 32 is configured in a U shape having a pair of upper and lower clamping pieces 33 and 34. The lock portion 32 is attached to the rib 12 in a state where the rib 12 is sandwiched from both the upper and lower surfaces by the both sandwiching pieces 33 and 34. The lower clamping piece 34 includes an engagement protrusion 36 on the upper surface thereof. The engagement protrusion 36 can be engaged with an engagement recess 14 formed on the lower surface of the rib 12 (FIGS. 3 and 4). A pair of slits 42 are formed on both sides of the lower holding piece 34 in the width direction so as to be cut from the tip side. As a result, on both sides of the sandwiching piece 34, flexible portions 40a forming a part of the grip portion 40 with the individual slits 42 therebetween are formed. The lower holding piece 34 is set to have a length protruding forward (leftward in FIGS. 2 and 3) from the upper holding piece 33 and the flexible portions 40a on both sides.

  The gripping portions 40 located on both sides of the lower holding piece 34 are composed of both flexible portions 40a and individual tape winding portions 40b that integrally project laterally from these flexible portions 40a. . Two portions of the free end portion 16a of the wire harness 16 can be individually coupled to these tape winding portions 40b by tape winding. Reinforcing ribs 38 that are continuous in two rows are provided between the upper surface of the upper sandwiching piece 33 and the lower surface of the flexible portion 40a in both grip portions 40. By these reinforcing ribs 38, the rigidity with respect to the bending of both gripping portions 40 (flexible portions 40a) is enhanced.

  The reason why the both gripping portions 40 are arranged on the lower holding piece 34 side of the lock portion 32 is related to the position of the rib 12 of the rear bumper 10. That is, the rib 12 of the rear bumper 10 is positioned near the upper portion inside the rear bumper 10 so as not to interfere with other wiring components, and is sufficient to accommodate the free end portion 16a of the wire harness 16 above the rib 12. Can't secure enough space. Therefore, the grip portion 40 cannot be disposed on the upper clamping piece 33 side of the lock portion 32, and as a result, is disposed on the lower clamping piece 34 side.

  In order to use the clamp 30 for temporary fastening, as described above, the free end portion 16a of the wire harness 16 is coupled to the tape winding portion 40b of both gripping portions 40 by tape winding. At this time, the free end portion 16 a of the wire harness 16 is positioned on the lower side of the lower holding piece 34 and the both gripping portions 40 in the lock portion 32. In this state, the lock portion 32 of the clamp 30 is attached to the rib 12 of the rear bumper 10. Thereby, the rib 12 of the rear bumper 10 is sandwiched from both the upper and lower surfaces by the both sandwiching pieces 33, 34 of the lock portion 32, and the engaging protrusion 36 of the lower sandwiching piece 34 is engaged with the engaging recess 14 of the rib 12. To do. Therefore, the free end portion 16a of the wire harness 16 is temporarily fastened to the rear bumper 10 as shown by the solid line in FIG.

  Thus, in the state where the free end portion 16 a of the wire harness 16 is temporarily fastened by the clamp 30, vibrations of the free end portion 16 a of the wire harness 16 and the connector 18 act on the clamp 30 while the rear bumper 10 is being transported. . This vibration and the free weight of the free end portion 16a and the connector 18 directly act on both gripping portions 40, and can be handled by the rigidity of both flexible portions 40a reinforced by the pair of reinforcing ribs 38. However, when a large vibration occurs in the free end portion 16a and the connector 18, both the flexible portions 40a bend together with the tape winding portion 40b.

  FIG. 5 is a side view showing a state in which the free end portion 16a of the wire harness 16 is vibrated greatly. As shown in this drawing, even if both gripping portions 40 bend downward together with the free end portion 16a of the wire harness 16, the bottom of the lock portion 32 separated by the slits 42 from the both flexible portions 40a of these gripping portions 40. The side holding piece 34 is prevented from being deformed. Therefore, the lock portion 32 of the clamp 30 does not come off from the rib 12 of the rear bumper 10, and the temporary fastening state of the free end portion 16a of the wire harness 16 with respect to the rear bumper 10 is properly maintained.

  In order to remove the temporary fastening of the free end portion 16a of the wire harness 16 from the rear bumper 10, the lower holding piece 34 of the lock portion 32 is bent downward, whereby the engagement protrusion of the rib 12 with respect to the engagement recess 14 is obtained. 36 can be disengaged. And the lock part 32 is pulled out from the rib 12, and the clamp 30 is removed from the rear bumper 10 side. As already described, since the lower holding piece 34 is longer than the other parts, the operation of bending the holding piece 34 downward is easy.

  As shown in FIG. 1, when the rear bumper 10 is mounted on the body 20, the operator holds the rear bumper 10 with one hand and removes the clamp 30 from the rib 12 with the other hand. After connecting the connector 18 of the wire harness 16 and the connector 24 of the wire harness 22 on the body 20 side, the rear bumper 10 is mounted.

  As described above, in the embodiment described based on the drawings, the rear bumper 10 and the body 20 are exemplified as the “attached member” and the “mating member”, but it is necessary to temporarily fix the wire harness. If it is a “mounting member”, another member may be used.
