  By the way, most of the wire harnesses for a vehicle are attached to a place where the user cannot touch in a normal use state of the vehicle. In this case, there is no particular problem even if the temporary fixing adhesive tape remains on the cable.

  On the other hand, some cables in the cable group of the wire harness may be attached to a place where the user can see. In this case, it is necessary to completely remove the torn temporary adhesive tape from the cable so as not to impair the aesthetic appearance of the vehicle. On the other hand, it is desired to save the labor required for removing the adhesive tape from the cable and discarding the removed tape piece.

  Moreover, when the protector shown by patent document 1 is employ | adopted, much effort, such as the man-hour to shape | mold a several unit body separately, and the man-hour which piles up and connects several unit bodies, is required. .

  The present invention provides a wire harness provided with a protective device, in which, when a part of cables are bent and bundled to reduce the load, the wire harness can be easily used as a vehicle support without deteriorating the appearance of the vehicle. It aims to provide a method of mounting.

The wire harness attachment method according to the first aspect of the present invention includes the steps shown below. A 1st process is a process of fixing the main-body part of the protector in a wire harness to the support body of a vehicle. The wire harness includes a cable group including a plurality of cables, a main body that covers the periphery of a part of the cable group, and a protector that includes a temporary fastening portion formed on an outer surface of the main body. . The temporary fastening portion holds the exposed cable in a bent state with a part of the exposed cable positioned outside the main body portion in the cable group interposed therebetween. A 2nd process is a process of removing the said exposed cable of the said cable group from the said temporary fixing part of the said protector, after the said main-body part is fixed to the said support body. A 3rd process is a process of connecting the edge part of the said exposed cable removed from the said temporary fixing part to another connection other party. Further, in the wire harness mounting method according to the first aspect, a plurality of cables in the cable group extend from one outlet of the protective device in a state before the main body portion is fixed to a vehicle support body. The cable is the exposed cable temporarily fixed to the temporary fixing portion of the protector, and the second cable is temporarily bound in a bent state by a binding material for temporary fixing.
The wire harness mounting method according to the second aspect of the present invention is the wire harness mounting method according to the first aspect, wherein the protective device is provided with an outlet different from the outlet, and from the additional outlet. A third cable in the extended cable group is temporarily bound together with the second cable in a bent state by the binding material for temporary fastening.

  In the package of the wire harness in the above aspect, the exposed cable exposed from the protector in the cable group is held in a bent state by a part of the exposed cable being sandwiched between the temporary fasteners of the protector. As a result, the exposed cables are reduced in size, and the package of the wire harness is reduced.

  And after the protector of a wire harness is fixed to the support body of a vehicle, an exposure cable is removed from a temporary fixing | fixed part, and the edge part of the exposure cable is connected to another connection partner. That is, the temporary fixing portion is a portion used until the wire harness is attached to the vehicle support, and is not a part of the wiring path of the exposed cable.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

<Wire harness>
First, a wire harness 10 employed in the wire harness mounting method according to the embodiment will be described with reference to FIG. The wire harness 10 is attached to a support such as a floor board below a seat in a vehicle, for example, and electrically connects a plurality of in-vehicle devices.

  As shown in FIG. 1, the wire harness 10 includes a cable group 1 and a protector 2.

<Cable group>
The cable group 1 includes a main line portion 11 including a plurality of cables and a branch line portion 12 including one or a plurality of cables branched from the main line portion 11. Each cable of the cable group 1 is an insulated wire having a conductor whose main component is, for example, copper or aluminum, and an insulating coating covering the periphery of the conductor. It is also conceivable that the cable group includes an optical fiber cable.

  In the example shown in FIG. 1, the first connector 31 is provided at the end portion of the main line portion 11, and the second connector 32 is provided at the end portion of the branch line portion 12.

  A part of the cable group 1 is a protected part 101 whose periphery is covered with the protector 2, and the remaining part of the cable group 1 is not covered with the protector 2. 2 is an exposed portion 102 exposed from 2.

  In the example shown in FIG. 1, the branch line portion 12 of the cable group 1 is an exposed portion 102 branched from the main line portion 11 outside the protector 2. The branch line portion 12 is an example of an exposed cable positioned outside the protector 2.

<Protective equipment>
The protector 2 is a tool that covers a part of the cable group 1 in order to protect the cable group 1. The protector 2 has a first member 201 and a second member 202 combined from both sides of the protected portion 101 of the cable group 1. Each of the first member 201 and the second member 202 is made of non-conductive material such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polyethylene terephthalate (PET), or polyamide (PA). It is a member in which synthetic resin is integrally molded.

  Part of the first member 201 and the second member 202 form a main body 21 that covers the periphery of the protected portion 101 of the cable group 1 in a combined state. Part of the first member 201 and part of the second member 202 constitute an engagement mechanism 203 that maintains the state in which the first member 201 and the second member 202 are combined.

  In the example shown in FIG. 1, the main body 21 of the protector 2 is formed in a branched cylindrical shape surrounding the branched portion (protected portion 101) of the main line portion 11 of the cable group 1.

  The main body 21 is formed with a cable fixing piece 23 that is bound by a binding material 4 such as an adhesive tape together with a part of the main line portion 11 of the cable group 1. By binding a part of the main wire portion 11 and the cable fixing piece 23 with the binding material 4, the position shift of the protector 2 with respect to the cable group 1 is prevented.

  A temporary fastening portion 24 that sandwiches a part of the exposed portion 102 of the cable group 1 is formed on the outer surface of the main body portion 21 of the protector 2. The temporary fastening portion 24 holds the exposed portion 102 in a bent state with a part of the exposed portion 102 (exposed cable) of the cable group 1 interposed therebetween.

  In the example shown in FIG. 1, the temporary fixing portion 24 holds the branch line portion 12 in a bent state with a part of the branch line portion 12 of the cable group 1 interposed therebetween.

  The temporary fastening portion 24 is, for example, a groove-like portion that sandwiches the branch line portion 12 when a part of the branch line portion 12 is inserted. In this case, the width of the groove in the temporary fixing part 24 in the natural state is formed to be slightly smaller than the diameter of the branch line part 12, and the temporary fixing part 24 sandwiches the branch line part 12 in the groove by elastic deformation. Moreover, it is also conceivable that a protrusion for preventing the branch line portion 12 from dropping off is formed near the opening of the groove in the branch line portion 12.

  Furthermore, the protector 2 has a fixing portion 22 connected to the main body portion 21. The fixing portion 22 is a portion that is fixed to a vehicle support. In the example shown in FIG. 1, the fixing portion 22 included in the protector 2 includes a clamp 221 that stays at the edge of the mounting hole in the plate-like support, and a bolt fixing portion 222 that is fixed to the support with a bolt. The bolt fixing portion 222 is formed with a through hole (bolt hole) through which the bolt is passed.

  In the example shown in FIG. 1, the main line portion 11 in the exposed portion 102 of the cable group 1 is disposed at a place where the user cannot touch it in a normal use state of the vehicle. Therefore, in the package of the wire harness 10, the main line portion 11 in the exposed portion 102 of the cable group 1 is temporarily bound by the temporarily fixing adhesive tape 5 in a state of being bent and small.

  The adhesive tape 5 for temporary fixing is an adhesive tape in which a plurality of cuts 51 are formed along the width direction. Such an adhesive tape 5 can be easily torn without using a blade.

  On the other hand, in the example shown in FIG. 1, the branch line portion 12 in the exposed portion 102 of the cable group 1 is disposed at a place where the user can see in the normal use state of the vehicle. Therefore, the branch line portion 12 is held in a bent state by the temporary fixing portion 24 sandwiching a part thereof. Thereby, the branch line part 12 is also bent and maintained in a small grouped state.

  Thus, the package of the wire harness 10 is smaller than the wire harness 10 in a state where the exposed portion 102 of the cable group 1 is not temporarily fastened.
