  The clip 1 in this embodiment is a clip for fixing a wire harness to an automobile body panel or the like. As shown in FIGS. 1-7, this clip 1 is connected to the clamp part A which clamps a wire harness, and this clamp part A, and fixes a wire harness to the predetermined attachment position of the vehicle body panel of a motor vehicle. It has an anchor part B. In use, with the wire harness held between the clamp portions A, the anchor portion B is inserted into the mounting hole of the vehicle body panel, and the wire harness is fixed to the predetermined mounting hole.

  The clamp part A of the clip 1 shown in the figure includes a support part 10 that supports the wire harness, a pressing part 20 that extends from one end side of the support part 10, and a ridge guide part 40 provided on the support part 10. These are integrally formed of a resin material such as polypropylene, polyethylene, or 66 nylon.

  The support part 10 in this embodiment has the support surface 11, and supports a wire harness with this support surface 11. FIG. The pressing portion 20 has a pressing surface 21 that faces the support surface 11, and the pressing surface 21 approaches and separates from the supporting surface 11 due to the bending (elasticity) of the pressing portion 20.

  In the clip 1 according to the present embodiment, when the wire harness 90 is sandwiched between the support surface 11 and the pressing surface 21, the pressing surface 21 causes the wire harness to support the supporting surface of the support portion 10 due to the elastic bias of the pressing portion 20. The wire harness 90 is clamped by being pressed against the wire 11. Note that the distance between the support surface 11 and the pressing surface 21 when the wire harness 90 is not sandwiched is designed to be smaller than the diameter of the wire harness 90 sandwiched between the clips 1.

  Moreover, the press part 20 in this embodiment has the press adjustment part 22 which adjusts the pressing force which clamps a wire harness. As shown in the figure, the presser adjusting portion 22 of the present embodiment is provided at the open end portion of the pressing portion 20 that forms the opening portion 30, that is, at the distal end portion of the pressing portion 20 that extends from one end side of the support portion 10. Is provided. In the opening 30, the open end of the pressing portion 20 is inclined toward the support portion 10, so that the opening is narrowed, and the disconnection of the wire harness held between the support surface 11 and the pressing surface 21 is suppressed. It is configured. The presser adjusting portion 22 extending at the distal end portion of the pressing portion 20 is provided to be inclined toward the direction in which the distal end is separated from the support portion 10 (the direction in which the narrow opening is widened). The holding surface 22a has a predetermined angle with respect to the extending direction. When an external force is applied to the pressing surface 22a of the pressing adjustment unit 22 configured as described above, the distance of the pressing unit 20 to the support unit 10 is adjusted according to the applied external force, and as a result, the pressing force for clamping the wire harness Is adjusted.

  Although not particularly limited, in the present embodiment, the length of the support portion 10 along the axial direction of the wire harness is formed to be longer than the length of the pressing portion 20 along the axial direction of the wire harness.

  Moreover, the clip 1 of this embodiment has the protrusion guide part 40 which guides the relative movement along the axial direction of a wire harness and the clamp part A. As shown in FIG. The ridge guide portion 40 is provided on the support surface 10 of the support portion 10, contacts the wire harness sandwiched between the support surface 11 and the pressing surface 21, and guides relative movement between the wire harness and the clamp portion A clip 1. . As shown in FIGS. 1-7, since the protrusion guide part 40 of this embodiment is continuously provided along the axial direction of a wire harness, it assists the movement along the axial direction of a wire harness, and a wire The relative movement along the axial direction of the harness and the clamp part A is guided.

  The length L40 along the axial direction of the wire harness of the protrusion guide portion 40 is a balance between the length L10 along the axial direction of the wire harness of the support portion 10 and the length L20 along the axial direction of the wire harness of the pressing portion 20. Can be set based on. For example, L20 × α20 ≦ L40 ≦ L10 × α10 can be set. Here, α20 is 0.7 ≦ α20 ≦ 1.0, and α10 is 0.7 ≦ α10 ≦ 1.0.

  As shown in FIG. 5, L20 ≦ L40 ≦ L10, specifically, L20 = L40 ≦ L10 × 0.7.

  Although not particularly limited, as shown in the figure, the ridge guide portion 40 of the present embodiment is disposed in the vicinity of the opening 30 where the support portion 10 and the pressing portion 20 approach and separate from each other. This protrusion guide part 40 forms the convex part which protrudes from the support surface 11, and also has the function to latch so that the inserted wire harness may not remove | deviate.

  In addition, although this embodiment shows the example of the clip 1 in which the ridge guide portion 40 is provided on the support surface 11 of the support portion 10, the ridge guide portion 40 may be provided on the pressing surface 21 of the pressing portion 20.

  Further, the clip 1 shown in the figure has a substantially arrow-shaped anchor portion B that becomes relatively thinner toward the tip side below the clamp portion A described above. The anchor portion B includes an umbrella-shaped (disk-shaped) substrate portion 60 provided at the boundary with the clamp portion A, a support column 61 suspended from the substrate portion 60, and the substrate portion 60 from the tip of the support column 61. It is comprised from a pair of locking piece 62 which has the flexibility formed in the direction of bending. On the free end side of the locking piece 62, an engaging step 62a that engages with the mounting hole of the vehicle body panel is formed.

  The state when the clip 1 is fixed will be described. As shown in FIG. 3, the anchor portion B of the clip 1 is inserted into a mounting hole 110 provided at a predetermined mounting position. When the anchor portion B is inserted into the mounting hole 110, the pair of locking pieces 62 are bent by the mounting hole 110, and when the substrate portion 60 comes into contact with the vehicle body panel 100, the umbrella-shaped substrate 60 is Since it is pressed against the panel 100 and spreads, the anchor part B is pushed back by the reaction force, the pair of locking pieces 62 are elastically restored, and the engaging stepped part 62a engages with the opening peripheral edge inside the mounting hole 110. The clip 1 is fixed to the vehicle body panel 100.

  Next, a state where the wire harness 90 is sandwiched between the clips 1 will be described. FIG. 8 is a perspective view showing a clip-attached wire harness in which the wire harness 90 is sandwiched between the clips 1.

  As shown in FIG. 8, the wire harness 90 is held in a state of being pressed against the support portion 10 by the elastic bias of the pressing portion 20. In this state, when the clip 1 is fixed and the wire harness 90 is moved or the wire harness 90 is fixed and the clip 1 is moved, the ridge guide portion 40 of the support portion 10 is moved in the axial direction between the wire harness 90 and the clamp portion A. Therefore, the holding position of the clip 1 can be moved along the axial direction of the wire harness 90 (arrow D1 and arrow D2 in FIG. 9).

  Moreover, the position of the clip 1 can be easily changed by weakening the pressing force of the pressing portion 20. Although the method of weakening the pressing force of the pressing part 20 is not particularly limited, when the pressing adjusting part 22 provided in the clip 1 of the present embodiment is used, the pressing part 20 is separated from the support part 10 (upward direction in FIG. 9). The external force may be applied to the presser adjusting unit 22. That is, when the pressing surface 22a is pressed, the pressing portion 20 is pushed upward, the distance of the pressing portion 20 to the support portion 10 is increased, and the pressing force that the pressing portion 20 presses the wire harness 90 against the support surface 11 is reduced. Can do. As described above, when the fixing position of the wire harness 90 is to be adjusted, the clip 1 with respect to the wire harness 90 can be obtained by applying an external force to the pressing surface 22a of the pressing adjusting unit 22 to weaken the pressing force for clamping the wire harness 90. Can be easily changed.

  Next, an operation for holding the wire harness between the clip 1 will be described. FIG. 9 is a front view of the clip 1 when the wire harness is clamped between the clips 1.

  As shown in FIG. 9, the wire harness 90 is inserted from the opening 30 of the support portion 10 and the pressing portion 20. When the wire harness 90 is inserted from the opening 30, when the external force in the direction in which the pressing portion 20 is separated from the support portion 10 (arrow F <b> 1 in FIG. 9) is applied to the pressing adjustment portion 22, the opening width of the opening 30 is reduced. Since it can expand, the wire harness 90 can be easily inserted in the clip 1.

  Further, in the clip 1 of the present embodiment, the distance from the ridge guide portion 40 provided in the support portion 10 to the base of the pressing portion 20 extending from one end side of the support portion 10 is held by the clip 1. When the clip 1 clamps the wire harness 90, a gap is formed between the inner surface of the clamp part A and the wire harness. Thereby, even if the wire harness 90 pressed by the elastic biasing of the pressing portion 20 is elastically deformed in the cross-sectional direction (even if it is in a crushed shape), the wire harness 90 is It is sandwiched between the support surface 11 and the pressing surface 21 while being guided by the guide portion 40.

  In addition, in embodiment, since the protrusion guide part 40 is arrange | positioned in the opening part 30 vicinity, and the wall is formed in the edge part of the support surface 11, the wire harness with which the clip 1 was mounted | worn is removed from the clip 1. Can be prevented.

  Next, an operation for removing the wire harness 90 from the clip will be described. FIG. 10 is a front view of the clip when the wire harness is removed.

  As shown in FIG. 10, the wire harness 90 is removed from the opening 30 between the support portion 10 and the pressing portion 20. When pulling out the wire harness 90 from the opening 30, if an external force in a direction (arrow F <b> 2 in FIG. 10) in which the pressing unit 20 is separated from the support unit 10 is applied to the pressing adjustment unit 22, the pressing force that holds the wire harness 90 is held. Therefore, the wire harness 90 can be easily detached from the clip 1.

  As described above, in the present embodiment, by applying an external force to the pressing adjustment portion 22, the wire harness 90 and the clamp portion A sandwiched between the support portion 10 and the pressing portion 20 are relatively aligned along the axial direction. Since it is movable, the position of the clip 1 on the wire harness 90 can be easily changed, and the routing workability of the wire harness 90 can be improved.

  By the way, in the conventional clip in which the clamp for holding the wire harness 90 is locked and the wire harness 90 is firmly held, in order to change the position of the clip, the clamp is unlocked using a jig or the like. There must be. Further, when the wire harness 90 is routed in the vehicle body panel 100, it is necessary to prevent the wire harness from sagging. For this reason, in the routing work using the conventional clip, after the clip is fixed to the mounting hole 110 of the vehicle body panel 100, the location where the clip is fixed is searched sequentially while the wire harness is routed, and the clip is clipped to that location It is necessary to lock the clamp by attaching, and workability of the routing process is poor. Moreover, in this routing method, since the clip 1 and the wire harness must be managed separately, the clip 1 may be lost in the vehicle interior.

  On the other hand, the clip 1 of the present embodiment does not hold the wire harness 90 by the lock mechanism, but in a state where the wire harness 90 is held between the support portion 10 and the pressing portion 20 of the clip 1. Since the harness 90 and the clamp portion A are configured to be relatively movable along the axial direction, the wire harness 90 is sandwiched between the support portion 10 and the pressing portion 20 of the clip 1 and then sequentially. A routing method in which the position of the clip 1 is adjusted in accordance with the pitch between the mounting holes 110 of the vehicle body panel 100 and the anchor portion B is inserted into the mounting hole 110 can be employed. Moreover, according to this routing method, since the clip 1 and the wire harness 90 are integrated, it is possible to prevent the clip 1 from being lost in the vehicle interior.

  Furthermore, since the clip 1 of this embodiment can fix the wire harness 90 only by inserting the wire harness 90 from the opening 30 of the clamp part A, the clip 1 is fixed to the mounting hole 110 of the vehicle body panel 100. Then, the workability can also be improved in the wiring method of attaching the wire harness 90 to the clip 1.

  Moreover, since the clip-attached wire harness is firmly attached at a predetermined pitch, it is necessary to prepare the number of products corresponding to the pitch type. Since the clip 1 is fixed to the wire harness 90 at a temporary pitch, the clip-attached wire harness can be shipped and the clip 1 can be fixed after changing the pitch at the site. The number of types of wire harnesses with clips can be reduced.
