【Example】

  Next, an embodiment of the clamp according to the present invention will be described with reference to FIGS. The same components as those of the conventional clamp 1 shown in FIG. 6 are designated by the same reference numerals in the drawings. And the description is omitted.

[0016]   As shown in FIGS. 1 and 2, the clamp 25 of this embodiment is the same as the splice portion 9 shown in FIG. A splicing portion 27 having a configuration, and a rod-shaped mounting portion 29 formed separately from the splicing portion 27, It is composed of the protrusion amount changing means 31.

[0017]   The protrusion amount changing means 31 is engraved on the lower portion of the panel locking portion 11 of the mounting portion 29. Screw portion 33, and a through hole 37 formed in the central portion of the pair of wing portions 7 of the splicing portion 27, , The screw-like protrusion 35 protruding from the inner wall 37a of the through hole 37. There is.

[0018]   As shown in FIG. 2, the screw portion 33 has a spiral groove along the axial direction of the mounting portion 29. Is formed. Further, the screw-shaped protrusion 35 is located in the inner peripheral direction of the through hole 37. Three protrusions are provided at regular intervals and at predetermined intervals in the axial direction of the through hole 37. ing. As shown in FIG. 3, a threaded portion 33 is screwed into the threaded projection 35, In this state, the mounting portion 29 is fixed in the through hole 37. Also, the mounting portion 29 and the splicing portion When moving relative to 27, the splicing part 27 is forcibly moved to the mounting part 29. To move.

[0019]   Next, in the fixing method of fixing the wire harness 3 to the panel 13 with the clamp 25 described above. explain about.

[0020]   The mounting portion 29 is inserted into the through hole 37 of the splicing portion 27, and the screw portion 33 is screw-shaped projection. The wire fixing portion 5 is attached to the wire harness 3 with the tape 4 while being screwed to the portion 35. The clamp 25 is fixed to the wire harness 3 by fixing it with 3. In addition, At this time, it is necessary that the rear end 9 of the mounting portion 29 projects from the wire harness 3. The protrusion distance L3 is preferably such that the operator can grip it. And mounting part 2 After inserting the panel locking portion 11 at the tip of 9 into the locking hole 13a of the panel 13, The stop portion 21 is locked to the opening edge of the locking hole 13a.

[0021]   After the locking step portion 21 is locked to the opening edge portion of the locking hole 13a, the mounting portion 29 is attached to the panel. At the same time as pulling in the direction away from 13, the contact portion 27 is pressed toward the panel 13. When the splicing portion 27 is pressed toward the panel 13, the threaded portion 33 of the mounting portion 29 is inserted into the through hole 37. Over the threaded projection 35 of the inner wall 37a of the inner wall 37a, and the splicing portion 27 moves to the panel 13 side. The wings 7 come into contact with the panel 13 by moving. Furthermore, the wing portion 7 abuts on the panel 13. The contact portion 27 is moved to the panel 13 side until the wing portion 7 is bent later. This allows you to The panel 13 is sandwiched between the locking step portion 21 of the flannel locking portion 11 and the abutment portion 27, The clamp 25 is fixed to the panel 13, and the wire harness 3 is fixed to the panel 13. Be done.

Thus, the distance between the locking step portion 21 and the wing portion 7 becomes shorter. If the panel 13 is thick, When the splicing portion 27 is located far from the panel 13, The distance becomes longer.

[0023]   Thus, according to the clamp 25 of the present embodiment, the splicing portion 27 is attached to the mounting portion 29. The thickness of the mounting portion 29 by changing the amount of protrusion of the mounting portion 29 from the splicing portion 27. If the panel is thin or thick, ensure that the panel 13 is pinched between the locking step 21 and the wing 7. It can be held, and the clamp 25 can be securely fixed to the panel.

[0024]   Therefore, in the clamp 25 of the present embodiment, the mounting portion 29 is separate from the abutment portion 27. Since the distance L2 between the locking step portion 21 and the abutting portion 27 is variable, the applicable plate thickness of the panel 13 The range increases.

[0025]   In addition, there were many types of wire clamps in the past due to the difference in applicable plate thickness. Since the applicable plate thickness range of the panel 13 of the clamp 25 of the kind can be enlarged, The number of clamps can be greatly reduced and parts management becomes easier.

[0026]   In addition, since the applicable plate thickness range is wide, the amount of use of one type of clamp increases, resulting in cost reduction. Can be reduced.

[0027]   Moreover, since the number of types of clamps can be significantly reduced, the wire harness 3 In the production process of, so-called mis-attachment that attaches different clamps is prevented. You can stop.

[0028]   Next, another embodiment will be described. In this embodiment, the clamp 25 of the above embodiment is used. Another use is to connect multiple panels, for example two panels 39, 41. This is an example used in the case.

[0029]   That is, as shown in FIG. 5, the locking holes 39a and 41a are formed in the panels 39 and 41, respectively. The panel locking portion 1 of the mounting portion 29 is provided in each of the locking holes 39a and 41a. 1 is passed through and the locking step portions 21 are respectively locked to the opening edge portions of the locking holes 39a. Then, the splicing portion 27 is pressed and moved toward the panels 39 and 41. This allows the locking step The panels 39 and 41 are sandwiched between the blade 21 and the wing portion 7 to connect the two panels. You can

[0030]   As described above, according to the present embodiment, it is possible to hold the sandwiched portion between the locking step portion 21 and the wing portion 7. Regardless of the thickness of the holding member (two panels 39 and 41 in the above example) The holding member can be reliably held.

[0031]   In the above embodiment, the panel locking portion 11 is a so-called clip. Not limited to this, other locking structures may be used.
