  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  First, with reference to FIGS. 1-4, the clamp 100 for wire harnesses by one Embodiment of this invention is demonstrated.

  As shown in FIGS. 1 and 2, the wire harness clamp 100 is configured to fix the wire harness 150 to the panel 160. The wire harness 150 is provided for power supply and signal transmission. The panel 160 is a component part of a vehicle (not shown), for example, and the wire harness clamp 100 has a function of defining the wiring position of the wire harness 150 in the vehicle. The wire harness clamp 100 is, for example, a resin molded product, and includes an attachment portion 1 and a clip portion 2 that are integrally formed.

  As shown in FIG. 2, the attachment portion 1 includes a plate 11, a band 12, and an insertion hole 13, and is configured to hold the wire harness 150 by the band 12. The plate 11 is formed with a band 12 and an insertion hole 13 at one end in the longitudinal direction (end on the X1 direction side). The band 12 is configured such that one end 121 is connected to the plate 11 and the other end can be inserted into the insertion hole 13. By inserting the band 12 into the insertion hole 13, the band 12 is formed in an annular shape, and the wire harness 150 is held by the annular band 12. That is, in the attachment portion 1, the wire harness 150 is attached to the plate 11 by the band 12.

  A plurality of engagement grooves 122 (see FIG. 1) are continuously formed on one surface of the band 12. An elastically deformable arm (not shown) is formed below the insertion hole 13, and an engagement groove 122 is engaged with the tip of the arm when the band 12 is to be removed from the insertion hole 13. A claw portion (not shown) is formed. For this reason, the band 12 can move with respect to the insertion hole 13 in the direction in which the band 12 is tightened (the direction in which the band 12 is inserted into the insertion hole 13), and the direction in which the band 12 is loosened (the band 12 extends from the insertion hole 13. Since the engaging groove 122 is engaged with the claw portion in the direction of extraction, the band 12 is difficult to move with respect to the insertion hole 13.

  The clip portion 2 is configured to be attachable to the attachment hole 161 of the panel 160 and is provided to fix the attachment portion 1 holding the wire harness 150 to the panel 160. The attachment hole 161 is, for example, a long hole, and is formed so as to penetrate the panel 160 in the thickness direction. The clip part 2 includes a shaft part (main body part) 21, a dish part 22, and a blade part 23, and is arranged at the other end part in the longitudinal direction of the plate 11 (end part on the X2 direction side).

As for the axial part 21, the dish part 22 is formed in the upper end part (one end part), and the blade | wing part 23 is formed in the lower end part (other end part).

  The dish portion 22 is formed in a dish shape (a bowl shape), and is formed such that the center portion is recessed upward with respect to the outer edge portion. As shown in FIG. 2, the other end portion of the plate 11 is connected to the upper side of the central portion of the dish portion 22. That is, the attachment portion 1 is arranged on one side (X1 direction side) with respect to the dish portion 22. As shown in FIG. 3, the dish portion 22 is formed in a track shape (rounded rectangular shape) in plan view and is larger than the mounting hole 161.

  As shown in FIG. 4, the blade portion 23 is provided at the lower end portion of the shaft portion 21 in a pair of left and right in the longitudinal direction (Y direction) of the dish portion 22. In addition, the longitudinal direction of the dish part 22 is a direction orthogonal to the longitudinal direction of the plate 11. The blade part 23 is formed so as to extend from the lower end part of the shaft part 21 to the dish part 22 side. That is, the blade portion 23 is formed so as to be folded back from the lower end portion of the shaft portion 21. The lower sides of the outer surfaces of the pair of blade portions 23 are inclined outward so as to be separated from each other as the plate portion 22 is approached. The wing | blade part 23 can be elastically deformed and the upper side is comprised so that opening and closing is possible. That is, the upper side of the blade portion 23 is configured to be swingable in the Y direction.

  Further, the blade portion 23 is formed with engaging portions 231a to 231c on the upper side of the outer surface. The engaging portions 231a to 231c are configured by steps that are recessed inward. The engaging portion 231a is disposed below and outside the engaging portion 231b, the engaging portion 231c is disposed above and inside the engaging portion 231b, and the engaging portion 231b is the engaging portion. It is arranged between 231a and 231c. Further, a pressing piece 232 for releasing the engagement is formed at the upper end portion (the end portion on the plate portion 22 side) of the blade portion 23. The pressing piece 232 is disposed in the internal space of the dish portion 22. As shown in FIG. 3, an inclined surface 232 a is formed on the outer surface of the pressing piece 232 so as to be inclined with respect to the short direction (X1 and X2 directions) of the dish portion 22 when viewed in plan. The inclined surface 232a is linearly inclined outward from the end portion on the X1 direction side toward the intermediate portion, and is inclined linearly outward from the end portion on the X2 direction side toward the intermediate portion.

  As shown in FIG. 4, the clip portion 2 is attached to the attachment hole 161 by inserting the shaft portion 21 of the clip portion 2 into the attachment hole 161 of the panel 160. In a state in which the clip portion 2 is attached to the attachment hole 161, the dish portion 22 is disposed on the front surface 160a side of the panel 160, and the engaging portion 231c is engaged with the back surface 160b of the panel 160. That is, the panel 160 is sandwiched between the dish portion 22 and the engaging portion 231c. For this reason, the clip part 2 is attached so as not to drop out of the attachment hole 161. The engaging portion 231c is engaged with a longitudinal edge portion of the attachment hole 161 which is a long hole. The engaging portions 231a and 231b are engaged when the clip portion 2 is attached to a panel (not shown) having a thickness larger than that of the panel 160.

  At this time, the pressing piece 232 is disposed on the surface 160 a side of the panel 160. Specifically, the pressing piece 232 is disposed in the internal space of the dish portion 22 and is disposed above the surface 160 a of the panel 160. That is, the pressing piece 232 protrudes from the surface 160 a of the panel 160 and is covered with the dish portion 22.

−Removal work of clamp for wire harness−
Next, with reference to FIG. 5 and FIG. 6, the removal operation | work from the attachment hole 161 of the panel 160 of the clamp 100 for wire harnesses by this embodiment is demonstrated. The removal work of the wire harness clamp 100 is performed using a bifurcated driver (clip remover) 200. The bifurcated driver 200 has a pair of claws 201 formed by branching the tip. The claw portion 201 is formed of a thin plate.

  First, as shown in FIG. 5, the claw portion 201 of the bifurcated driver 200 is inserted between the surface 160 a of the panel 160 and the plate portion 22 of the clip portion 2. The bifurcated driver 200 is inserted, for example, from the other side (X2 direction side) with respect to the dish part 22, that is, from the side where the plate 11 of the attachment part 1 is not disposed with respect to the dish part 22. At this time, the dish portion 22 is elastically deformed by the insertion of the bifurcated driver 200.

  When the claw portion 201 of the bifurcated driver 200 is inserted, the claw portion 201 is brought into contact with the inclined surface 232a of the pressing piece 232, and the pressing piece 232 is pushed inward. For this reason, as shown in FIG. 6, when the blade | wing part 23 bends inward, engagement of the engaging part 231c with respect to the back surface 160b of the panel 160 is cancelled | released. At this time, the engaging portions 231a to 231c are arranged in the mounting hole 161, and the shaft portion 21 and the blade portion 23 of the clip portion 2 can be extracted. Thereafter, when the bifurcated driver 200 is lifted upward with respect to the panel 160, the plate portion 22 of the clip portion 2 is moved upward, and the shaft portion 21 and the blade portion 23 are extracted from the mounting hole 161.

  Thus, the clip part 2 is removed from the surface 160a side of the panel 160 (the side where the wire harness 150 is disposed with respect to the panel 160) while the wire harness 150 is attached to the attachment part 1.

-Effect-
In the present embodiment, as described above, the pressing piece 232 is formed at the upper end portion of the blade portion 23, thereby inserting the bifurcated driver 200 between the surface 160 a of the panel 160 and the dish portion 22. Since the blade portion 23 can be elastically deformed by pushing 232, the engagement of the engagement portion 231c with the back surface 160b of the panel 160 can be released. Thereby, since the clip part 2 can be removed from the surface 160a side of the panel 160 while the wire harness 150 is attached to the attachment part 1, the work of removing the wire harness clamp 100 from the attachment hole 161 is performed. Can be improved. That is, in the wire harness clamp 100 of the present embodiment, the clip part 2 can be removed from the attachment hole 161 of the panel 160 without removing the wire harness 150 from the attachment part 1.

  Further, in the present embodiment, by forming the inclined surface 232a on the pressing piece 232, both the pair of pressing pieces 232 can be pushed inward by the insertion of the bifurcated driver 200, so that the pair of engaging portions 231c Both engagements can be released. Thereby, the removal from the attachment hole 161 of the clamp 100 for wire harnesses can be made easier.

  In the present embodiment, since the bifurcated driver 200 is inserted from the other side with respect to the plate portion 22, the attachment portion 1 does not hinder when the bifurcated driver 200 is inserted, and therefore the surface 160 a of the panel 160 and the plate portion 22. The bifurcated driver 200 can be easily inserted between the two.

  Further, in the present embodiment, by forming the engaging portions 231a to 231c in the blade portion 23, the clip is applied to three types of panels having different thicknesses (the panel 160 and two types of panels having a thickness larger than the panel 160). Part 2 can be attached. That is, any one of the engaging portions 231a to 231c is engaged with the back surface of the panel according to the thickness of the panel.

  Further, in the present embodiment, the attachment hole 161 is a long hole, and the clip portion 2 is positioned with respect to the panel 160 by engaging the engagement portion 231 c with the longitudinal edge portion of the attachment hole 161. The orientation of the wire harness 150 attached to the attachment portion 1 can be prevented from changing.
