  Hereinafter, the best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be described with reference to the drawings.

  The wiring clip 10 shown in FIGS. 1 and 2 fixes a wire harness routed inside a vehicle such as an automobile to a panel 54 of the vehicle. In the present embodiment, as shown in FIG. 2, the connector 50 provided at the end of the wire harness is attached to the wiring clip 10. Further, in order to easily remove the connector 50 attached to the panel 54 (shown in FIG. 3), the locking post 12 of the wiring clip 10 is provided with a V-shaped notch (breaking portion 17). . The connector 50 can be easily detached from the panel 54 by breaking and breaking the broken portion 17. Furthermore, as shown in FIG. 3, the protective member 30 is crowned by the breakage portion 17 so that the breakage portion 17 does not break unintentionally. Hereinafter, the configuration of the wiring clip 10 will be described, and then the protection member 30 and the removal of the connector 50 attached to the panel 54 will be described.

  As shown in FIGS. 1 and 2, the wiring clip 10 includes a flat plate-like mounting portion 14 and a locking portion 11 that continues from the mounting portion 14. As a material of the wiring clip 10, for example, there is a synthetic resin, and any material can be used as long as a member such as a wire harness can be appropriately locked to a panel or the like in a desired period. The locking portion 11 is locked in a fixing hole 56 provided in the panel 54 of the vehicle (see FIG. 3). Here, the attachment portion 14 is formed in a band plate shape, and as shown in FIG. 2, the attachment portion 14 is connected to the connector 50 by engaging the fixing portion 52 provided in the connector 50 and the attachment portion 14. It is fixed to the wire harness equipped with.

  In general, a wire harness includes a plurality of covered electric wires, a connector 50 attached to an end portion of the electric wires, and the like. The connector 50 includes a conductive terminal fitting and an insulating connector housing, and the terminal fitting is electrically connected to the core wire of the electric wire. In the wire harness, the connector 50 is coupled to connectors of various electronic devices, and transmits electric power and various signals to these electronic devices. In addition, in this embodiment, although the connector 50 of a wire harness is attached to the clip 10 for wiring, it is not restricted to this, The electric wire of a wire harness may be attached to the clip 10 for wiring.

  The locking portion 11 includes a locking column 12 continuous from the mounting portion 14, a locking head 29 provided at the end of the locking column 12, and a breaking portion 17 provided in the locking column 12. It is prepared as one. Here, the locking column 12 extends from the mounting portion 14 along a direction orthogonal to the surface of the mounting portion 14.

  Further, the locking head 29 is formed at an end portion extending from the mounting portion 14 in the locking column 12 and includes a pair of locking pieces 15. Specifically, the locking piece 15 is suspended from the top 21 of the locking head 29 continuous with the locking column 12 toward the attachment portion 14 in an open leg shape. Further, step locking portions 16 each having a shape in which an outer edge portion is notched are formed at the end portions of the locking pieces 15. Further, the pair of locking pieces 15 can be elastically deformed in a direction in which the step locking portions 16 as end portions approach each other (in the arrow direction in FIG. 2).

  The breaking portion 17 is provided in the vicinity of the mounting portion 14 of the locking column 12 (hereinafter referred to as “base portion 13”), and is a groove (notch) formed in a V shape on both sides of the outer surface of the locking column 12. Consists of. As a result, the fracture portion 17 has a cross-sectional area of the transverse cross section of the locking column 12 that is minimized.

  In the locking column 12, a pair of symmetrical support pieces 18 are formed between the break portion 17 and the locking head 29 so as to extend outward from the locking column 12 slightly obliquely upward. .

  Here, the wiring clip 10 has the connector 50 fixed to the vehicle panel 54 as shown in FIG. In the fixing procedure, first, the locking portion 11 is made to face the fixing hole 56 of the panel 54. Subsequently, the locking portion 11 is inserted into the fixing hole 56 from the top portion 21 of the locking head 29. Then, the pair of locking pieces 15 are elastically deformed once in a direction approaching each other. Further, when the step locking portion 16 of the pair of locking pieces 15 enters the fixing hole 56, the step locking portions 16 of the pair of locking pieces 15 are displaced in a direction away from each other by the elastic restoring force.

  Then, the step locking portion 16 contacts the inner edge of the fixing hole 56. Thereby, the step locking portion 16 of the locking portion 11 is locked in the fixing hole 56 provided in the panel 54. Further, the outer edge portion 19 of the support piece 18 contacts the surface of the panel 54. Thus, the wiring clip 10 fixes the connector 50 to the panel 54.

  Next, a procedure for removing the connector 50 fixed to the panel 54 by the wiring clip 10 from the panel 54 will be described with reference to FIG. First, the connector 50 (mounting portion 14) is displaced in a direction of bending to the left or right with respect to the vertical axis 40 or a direction of twisting. Then, bending stress and torsional stress concentrate on the fracture portion 17 where the cross-sectional area of the locking column 12 is minimum. When the operation of displacing the connector 50 is performed a predetermined number of times or more than a predetermined amount, plastic fracture occurs, and the fracture portion 17 is fractured. By doing so, the connector 50 (wire harness) can be easily detached from the panel 54. In addition, since the outer edge portion 19 of the support piece 18 is in contact with the surface of the panel 54, the wiring clip 10 is disengaged from the fixing hole 56 of the panel 54 during the operation of displacing the connector 50. You can prevent it from entering.

  By the way, when the connector 50 is packed or attached to the panel 54 of the vehicle body, it is sometimes necessary to take measures to prevent the breaking portion 17 from being unintentionally broken. Therefore, in the present embodiment, the protective member 30 shown in FIGS. 6 and 7 is crowned on the fracture portion 17 as shown in FIG.

  Specifically, as shown in FIG. 6, the protective material 30 has, for example, a U shape in a plan view, and has a substantially central portion on the inner surface from one end 35 a to the other end 35 b of the opening. For example, a convex portion 34 having a triangular cross section is formed. Further, as the material of the protective material 30, for example, the same synthetic resin as the wiring clip 10, or wood, metal, or the like is assumed, and the fitting is appropriately fitted to the fracture portion 17 of the wiring clip 10 in a desired period. Any material that can be maintained is acceptable.

  Further, the convex portion 34 has a shape that engages and closely contacts the V-shaped notch of the fracture portion 17. Therefore, the protective material 30 is inserted into the locking column 12 so that the convex portion 34 is engaged with the notch and the fracture portion 17 is further sandwiched. As a result, the fracture portion 17 is crowned by the protective material 30.

  As described above, the broken portion 17 can be reinforced by covering the broken portion 17 with the protective material 30. Since the protective member 30 is covered with the rupture portion 17, the rupture portion 17 becomes immovable and, for example, bending stress or the like does not act on it, and as a result, the rupture portion 17 is easily broken. I can prevent that.

  On the other hand, when it is desired to remove the connector 50 from the panel 54 to which the connector 50 is fixed, the operator removes the protective material 30 from the locking column 12 and displaces the connector 50 as shown in FIG. 17 is broken. In addition, the protective material 30 is only inserted in the longitudinal direction of the cross section of the locking column 12 in a state where it is covered with the fracture portion 17, and is not particularly locked in the longitudinal direction. Therefore, the operator can easily remove the protective material 30 from the locking column 12.

  As mentioned above, according to this embodiment, when attaching and fixing members, such as a wire harness, to a desired location, the removal operation | work can be made easy, maintaining attachment strength.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of the respective components, and such modifications are within the scope of the present invention.

  For example, the shape of the convex portion 34 formed on the protective material 30 is not limited to a triangular cross section, but may be any shape that fits into the shape of the fracture portion 17 and makes the fracture portion 17 immovable. In addition, the cross section may be circular or rectangular. Further, the size of the convex portion 34 may not always be constant. Furthermore, the convex part 34 does not need to be formed in the part that is not fitted to the fracture part 17, and a part of the part that is fitted may be discontinuous.

  Further, the breaking portion 17 is provided in the vicinity of the attachment portion 14 of the locking column 12, but is not limited thereto, and may be provided in any portion of the locking column 12. Furthermore, although the wire harness is attached to the vehicle, the present invention is not limited to this. For example, the present invention can also be applied to a product in which the wire harness is used in home appliances.

  It can be widely used as a fixture for attaching a member such as a wire harness to a panel.
