  The wire bundle branching portion fixing member 1 according to the present embodiment is a member for fixing a branching portion of an electric wire bundle composed of a plurality of electric wires to an attachment target, and is attached to the branching portion. The wire bundle to which the wire bundle branching portion fixing member 1 and the like are attached is routed in a vehicle such as an automobile as a wire harness. The branch portion of the wire bundle is fixed to, for example, a vehicle body panel or the like by the wire bundle branch portion fixing member 1. Thereby, the position of the branch part of an electric wire bundle is fixed, and it is suppressed that the said branch part interferes with the circumference | surroundings. As a result, the branch portion of the wire bundle can be protected. Hereinafter, the wire bundle branching portion fixing member 1 is simply referred to as “fixing member 1”. Further, “attachment object” means an object to which the branch portion of the wire bundle is fixed by the fixing member 1.

  The fixing member 1 is made of, for example, resin. The fixing member 1 includes a clip portion 2 that is locked in an attachment hole of an attachment object, a rod-like portion 3, and an electric wire fixing portion 4 to which an electric wire at a branch portion of the electric wire bundle is fixed with a tape. The clip part 2, the rod-like part 3, and the electric wire fixing part 4 are integrally formed.

  The rod-shaped portion 3 extends from the clip portion 2 and has a tapered round bar shape. The tip of the rod-shaped portion 3 (the end opposite to the clip portion 2 side) is rounded. The rod-like part 3 is inserted into the branch part of the electric wire bundle. In more detail, the rod-shaped part 3 is inserted between the electric wires in the branch part of the electric wire bundle.

  The clip part 2 includes a locking head 20, a dish-like part 21, and a connecting part 22 connected to the rod-like part 3 and the wire fixing part 4. The connecting portion 22 has a rectangular parallelepiped shape, for example. For convenience of explanation, among the six surfaces constituting the surface of the connecting portion 22, the lower surface in FIG. 1 is the “bottom surface 22 a”, the upper surface in FIG. 1 is the “upper surface 22 b”, and the other four surfaces. Each of the two surfaces is referred to as “side surface 22c”.

  One end of the rod-like portion 3 is connected to the bottom surface 22 a of the connecting portion 22. That is, the rod-like portion 3 extends from the bottom surface 22 a of the connecting portion 22. Further, the electric wire fixing portion 4 is connected to one side surface 22 c of the connecting portion 22.

That is, in the branch part 500, the electric wire route 510 through which the branch line 151 passes, the electric wire route 510 through which the left portion of the trunk line 150 passes through the paper 151, and the electric wire through which the portion of the main line 150 passes through the right portion of the paper 151 from the branch line 151. A path 510 exists. A plurality of electric wires 5 exist in each of the three electric wire paths 510. Note that the plurality of electric wires 5 existing in the electric wire path 510 may also be referred to as “wire bundles”.

  A fixing member 1 shown in FIG. 9 is attached to a T-shaped branch portion 500 as shown in FIG. 8, and is fixed to an attachment object by the fixing member 1. In the fixing member 1 shown in FIG. 9, two accessory parts 10 are attached to the rod-like portion 3. That is, the number of accessory parts 10 that is one less than the number of the plurality of electric wire paths 510 in the branch portion 500 to which the fixing member 1 is attached is attached to the rod-like portion 3 of the fixing member 1. Thereby, the number of the accessory parts 10 and the electric wire fixing | fixed part 4 in the fixing member 1 and the number of the some electric wire paths 510 in the branch part 500 to which the said fixing member 1 is attached correspond. The two attachment parts 10 of the fixing member 1 are rotated around the rod-like part 3 and are respectively arranged on the electric wire bundles of the two electric wire paths 510 in the branch part 500. The electric wire fixing portion 4 of the fixing member 1 is disposed on the electric wire bundle of the other electric wire path 510 in the branch portion 500. In each accessory part 10, a tape is wound around the plate-like portion 100 together with the wire bundle of one electric wire path 510 on which the accessory part 10 is disposed. In the electric wire fixing part 4, a tape is wound around the plate-like part 40 together with the electric wire bundle of one electric wire path 510 in which the electric wire fixing part 4 is arranged. As a result, the fixing member 1 is attached to the branch portion 500 of the wire bundle 50. And the branch part 500 is fixed to the attachment target object 300 by attaching the fixing member 1 attached to the branch part 500 to the attachment hole 300a of the attachment target object 300 as mentioned above.

  Next, processes from branching the wire bundle to attaching the fixing member 1 to the branch portion of the wire bundle will be described. That is, the manufacturing method of the wire harness with which the fixing member 1 was attached with respect to the branch part of an electric wire bundle is demonstrated. In the following description, as an example, a process from creation of the branch portion 500 of the wire bundle 50 shown in FIG. 8 to attachment of the fixing member 1 shown in FIG. 9 to the branch portion 500 will be described.

  When the electric wire bundle 50 is branched to create the T-shaped branch portion 500, for example, a support jig 6 that supports the electric wire bundle 50 as shown in FIG. 10 is used. The branch portion 500 of the wire bundle 50 is produced when the wire bundle 50 is wired on the drawing board (work board). A plurality of support jigs including the support jig 6 are arranged on the drawing board, and the wire bundle 50 is wired by being supported by the plurality of support jigs.

  As shown in FIG. 10, the support jig 6 includes an attachment portion 60 attached to the drawing board, a support portion 62 that supports the electric wire bundle 50, and a column portion 61 that connects the attachment portion 60 and the support portion 62.

The connecting portion 621 is provided on the column portion 61. Each rod-shaped portion 620 extends from the connecting portion 621 in the horizontal direction and then extends upward.

  The wire bundle 50 is supported by the support portion 62 of the support jig 6 so as to pass between the plurality of rod-shaped portions 620 of the support jig 6. Then, as shown in FIG. 11, the branch portion 500 is produced by bending a part of the plurality of wires 5 of the trunk line 150 of the wire bundle 50 using the rod-like portion 620 of the support jig 6.

  When the branch portion 500 is formed in the wire bundle 50, the rod-like portion 3 of the fixing member 1 is inserted into the branch portion 500 supported by the support jig 6, as shown in FIG. At this time, the rod-like portion 3 is inserted into the branch center 500a (see FIG. 11) of the branch portion 500. Thereby, when the fixing member 1 is viewed from the front end side of the clip portion 2 (viewed from the top surface of the fixing member 1), the center of the clip portion 2 is positioned immediately above the branch center 500a. In other words, the central axis of the clip part 2 extending in the insertion direction DR of the clip part 2 passes through the branch center 500a.

  Further, when the rod-like portion 3 of the fixing member 1 is inserted into the branching portion 500, the electric wire fixing portion 4 of the fixing member 1 is connected to the electric wire of one electric wire path 510 in the branching portion 500 as shown in FIG. Arranged on the bundle. Further, the two attachment parts 10 of the fixing member 1 are rotated around the rod-like portion 3 so as to be positioned on the other two electric wire paths 510 at the branch portion 500, respectively. Each is arranged on a wire bundle.

The adhesive tape 7 is wound. At this time, the adhesive tape 7 is prevented from being wound around the protrusion 101 of the accessory 10. In addition, when the adhesive tape 7 is wound around the branch portion 500, the wire fixing portion 4 is arranged with respect to the plate-like portion 40 of the wire fixing portion 4 of the fixing member 1. The said adhesive tape 7 is wound with an electric wire bundle. At this time, the adhesive tape 7 is prevented from being wound around the protruding portion 41 of the wire fixing portion 4. FIG. 14 is a diagram illustrating a state where the adhesive tape 7 is wound around the branch portion 500 and the branch portion 500 is bound. When bundling the branch portion 500, only one adhesive tape 7 may be used, or a plurality of adhesive tapes 7 may be used.

  Thus, in the present embodiment, when the adhesive tape 7 is wound around the branch portion 500 of the wire bundle 50 and the branch portion 500 is bound, the rod-shaped portion 3 of the fixing member 1 is inserted into the branch portion 500. In this state, the adhesive tape 7 is wound around the electric wire fixing portion 4 of the fixing member 1 together with the electric wire bundle of the electric wire path 510, and the attachment part 10 of the fixing member 1 is attached to the electric wire fixing portion 4. The adhesive tape 7 is wound together with the wire bundle of the wire path 510 where it is disposed. Thereby, bundling of the branch part 500 and attachment of the fixing member 1 to the branch part 500 are performed simultaneously. When the branch portion 500 is bound and the fixing member 1 is attached to the branch portion 500, a wire harness having the wire bundle 50 and the fixing member 1 as shown in FIG. 14 is completed. About this wire harness, the branch part 500 of the wire bundle 50 is fixed to the said attachment target object, when the clip part 2 of the fixing member 1 latches in the attachment hole of attachment objects, such as a vehicle body panel. As described above, since the central axis of the clip part 2 extending in the insertion direction DR of the clip part 2 with respect to the attachment hole of the attachment object passes through the branch center 500a of the branch part 500, the clip part 2 is By latching in the attachment hole, the branch portion 500 can be fixed to the attachment object at the branch center 500a of the branch portion 500. Thereby, when setting the length of each part (branch line etc.) of a wire harness on the basis of the branch center 500a of the branch part 500, the dimensional accuracy of the length of each part can be improved.

  In the above example, the fixing member 1 to which the accessory part 10 is attached is used to fix the branch portion 500 of the wire bundle 50 to the object to be attached, but the fixing member to which the accessory part 10 is not attached. 1 may be used to fix the branching portion 500 to the attachment object. In this case, the adhesive tape 7 is wound around the wire fixing portion 4 of the fixing member 1 together with the wire bundle in one of the plurality of electric wire routes 510 in the branch portion 500, whereby the fixing member 1 is It will be attached to the branch part 500.

  Moreover, you may fix the branch part 500 of the wire bundle 50 to an attachment target object using the fixing member 1 to which only the one accessory component 10 was attached. In this case, the adhesive tape 7 is wound around the wire fixing portion 4 of the fixing member 1 together with the wire bundle in one of the plurality of wire routes 510 in the branching portion 500, and further in the branching portion 500. The fixing member 1 is attached to the branch portion 500 by winding the adhesive tape 7 around one accessory part 10 of the fixing member 1 together with the wire bundle in the other one of the plurality of electric wire paths 510. become.

Even with such a fixing member 1, the T-shaped branch portion 500 shown in FIG. 8 can be attached to the attachment object.

  As described above, in the present embodiment, the adhesive tape 7 is wound around the electric wire fixing portion 4 of the fixing member 1 together with the electric wires 5 in a state where the rod-like portion 3 of the fixing member 1 is inserted into the branch portion 500 of the electric wire bundle 50. Yes. Therefore, in a state where the fixing member 1 is positioned at a desired position of the branching portion 500 by inserting the rod-like portion 3 into a desired position of the branching portion 500 (the branching center 500a in the above example), the fixing member 1 is fixed with the adhesive tape 7. It can be attached to the branch part 500. Therefore, the precision of the attachment position with respect to the branch part 500 about the fixing member 1 can be improved.

  On the other hand, like the fixing member described in Patent Document 1 described above, if the fixing member 1 is not provided with the rod-like portion 3, the fixing member 1 is simply placed on the branch portion 500. However, when the fixing member 1 is attached to the branch portion 500 with the adhesive tape 7, there is a possibility that the fixing member 1 is displaced from a desired location of the branch portion 500. Therefore, in this case, the accuracy of the mounting position of the fixing member 1 with respect to the branch portion 500 is lowered.

  On the other hand, in the case of using the fixing member 1 not provided with the rod-like portion 3, the fixing member 1 is positioned with respect to the branch portion 500 using a positioning jig attached to the drawing board. It is possible to attach the fixing member 1 to the branch portion 500 with a tape. However, in this case, the working device becomes complicated and the working efficiency decreases.

  Furthermore, when using a positioning jig, the positioning jig may interfere with the rod-shaped portion 620 of the above-described support jig 6 that supports the branch portion 500. In this case, the branch portion 500 is removed from the support jig 6, and the fixing member 1 is positioned with respect to the branch portion 500 while the operator holds the branch portion 500 in his / her hand. When the operator has the branching part 500 in his / her hand, the position of the branching part 500 is inevitably shifted. Therefore, even if a positioning jig is used, the accuracy of the mounting position of the fixing member 1 relative to the branching part 500 is high. It will decline.

  In the present embodiment, the fixing member 1 is attached to the branch portion 500 with the adhesive tape 7 in a state where the fixing member 1 is positioned at the desired position of the branch portion 500 by inserting the rod-like portion 3 into the desired position of the branch portion 500. Therefore, the accuracy of the mounting position of the fixing member 1 with respect to the branch portion 500 can be easily improved.

  Further, when the positioning jig interferes with the support jig 6, it is necessary to remove the branch portion 500 from the support jig 6 after binding the branch portion 500 with an adhesive tape so that the shape of the branch portion 500 is not disturbed. There is. Therefore, in this case, after binding the branch portion 500, the fixing member is attached to the branch portion 500 with an adhesive tape.

  On the other hand, in this embodiment, when the adhesive tape 7 is wound around the branch portion 500 and the branch portion 500 is bound, the rod-like portion 3 is inserted into the branch portion 500 and the electric wire fixing portion 4 together with the electric wire 5. Since the adhesive tape 7 can be wound, the fixing member 1 can be attached to the branch portion 500 at the same time as the branch portion 500 is bound. Therefore, the work man-hour is reduced and the work efficiency is improved.

  Moreover, in this Embodiment, since the accessory 10 attached to the said rod-shaped part 3 in the state rotatable around the rod-shaped part 3 of the fixing member 1 is provided, with respect to the branch part 500 of various shapes The fixing member 1 can be firmly attached.

  FIG. 16 is a diagram illustrating a state in which the fixing member 1 is attached to the Y-shaped branch portion 500. As shown in FIG. 16, when the fixing member 1 to which the two accessory parts 10 are attached is attached to the Y-shaped branch portion 500, the electric wire fixing portion 4 and The two accessory parts 10 are rotated around the rod-shaped part 3 so that the two accessory parts 10 are Y-shaped, and each of the accessory parts 10 is bundled in one wire path 510 at the branch part 500. The electric wire fixing part 4 is arranged on the electric wire bundle in one electric wire path 510 in the branch part 500 while being arranged on the upper side. Then, the adhesive tape 7 is wound around the branch portion 500 in order to bind the branch portion 500. At this time, the adhesive tape 7 is wound together with the wire bundle of the electric wire path 510 in which the accessory part 10 is arranged, and the electric wire bundle of the electric wire path 510 in which it is arranged with respect to the electric wire fixing portion 4. At the same time, the adhesive tape 7 is wound. As a result, the fixing member 1 is attached to the Y-shaped branch portion 500. In this way, by adjusting the angle of the accessory part 10, the same fixing member 1 used when fixing the T-shaped branch part 500 to the attachment object is used, and the Y-type branch part 500 is attached to the attachment object. Can be fixed to objects.

  FIG. 17 is a diagram illustrating a state in which the fixing member 1 is attached to the branch portion 500 having the five electric wire paths 510. In the fixing member 1 shown in FIG. 17, four accessory parts 10 are attached to the rod-like portion 3. When the fixing member 1 to which the four accessory parts 10 are attached is attached to the branch part 500, each accessory part 10 is rotated around the rod-like part 3, and each accessory part 10 is turned into the branch part 500. The electric wire fixing part 4 is arranged on the electric wire bundle in one electric wire path 510 in the branch part 500. Then, the adhesive tape 7 is wound around the branch portion 500 in order to bind the branch portion 500. At this time, the adhesive tape 7 is wound together with the wire bundle of the electric wire path 510 in which it is arranged with respect to the accessory part 10, and together with the electric wire bundle of the electric wire path 510 in which it is arranged with respect to the electric wire fixing portion 4. The adhesive tape 7 is wound. Thereby, the fixing member 1 is attached to the branch part 500 having the five electric wire paths 510. In this way, by adding two attachment parts 10 to the fixing member 1 used when fixing the T-type or Y-type branch part 500 to the attachment object, the branch having five electric wire paths 510 is added. It becomes possible to fix the part 500 to an attachment target object.

  As in this embodiment, the fixing member 1 is attached to the number of the electric wire fixing portion 4 provided on the fixing member 1 and the accessory part 10 attached to the rod-like portion 3 of the fixing member 1.
