  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.

<First Embodiment>
<1. Overall configuration of electric wire with protective member>
The entire configuration of the protective member-equipped electric wire according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 shows a plan view of the electric wire 1 with a protective member, and FIG. 2 shows a side sectional view of the electric wire 1 with a protective member shown in FIG.

  The electric wire 1 with a protection member includes an electric wire 2. As the electric wire 2, what constitutes a wire harness for interconnecting various electric devices in a vehicle or the like is assumed. In addition, the electric wire 2 with which the electric wire 1 with a protective member is provided may be one, and may be plural. That is, the electric wire 2 may be an electric wire bundle in which a plurality of electric wires 2 are bundled.

  The electric wire 1 with a protective member includes a protective member 3. The protective member 3 functions as a protective member that protects the electric wire 2 and also functions as a shape regulating member that regulates the electric wire 2 to a predetermined laying shape.

  The protection member 3 includes a flat rectangular base portion 31 and a plurality of protrusions 32 erected on the entire one main surface (first main surface) of the base portion 31. Each protrusion 32 is a cylindrical protrusion, and is disposed on a lattice point. Each projection 32 preferably has a polygonal shape (for example, a rectangular shape) with rounded corners (rounded) in plan view. Each protrusion 32 preferably has a shape (tapered shape) in which the tip is slightly narrowed. Moreover, the bottom and top of each protrusion 32 may be closed or open. By making the plurality of protrusions 32 into a cylindrical shape, the advantage that the protective member 3 can be reduced in weight can be obtained.

  A gap formed between the protrusion 32 and the protrusion 32 is a path through which the electric wire 2 can be wound. Each protrusion 32 constitutes a branching portion of the path. That is, the plurality of protrusions 32 are arranged on the lattice points, whereby a lattice-like route network is formed on the first main surface of the protection member 3. The electric wire 2 is regulated in a shape along the selected route by being arranged in a state along the selected route set for the route network, and in this state, a position (fixed position) in which the extending direction is determined ) It is fixed to the protective member 3 at P. If each of the plurality of protrusions 32 is formed in a polygonal shape with rounded corners, it is possible to obtain an advantage that the electric wire 20 wound along the protrusions 32 is hardly damaged.

  The protection member 3 further includes a through hole 33 formed on the end side of the base portion 31. The through hole 33 is a hole (a through hole for attaching a fixed part) for inserting a fixing part for fixing the electric wire with protective member 1 at a fixed position of a vehicle or the like.

<2. Manufacturing method of electric wire with protective member>
Next, a method for manufacturing the electric wire 1 with a protective member will be described with reference to FIG. FIG. 3 is a diagram for explaining a method of manufacturing the electric wire 1 with a protective member.

  As described above, a lattice-like route network is formed on the first main surface of the protection member 3, and an infinite number of routes can be selected therefrom. In the first step, the route on which the electric wire 2 is to be disposed is selected from the route network formed on the first main surface of the protective member 3 (the upper part of FIG. 3. In the upper part of FIG. 3, the route is selected. Are shown with a dashed line).

  In the second step, the electric wire 2 is disposed on the first main surface of the protective member 3 so that the protrusions 32 are spaced along the path selected in the first step (see FIG. 3). Middle). Thereby, the electric wire 2 will be in the state regulated by the shape along the selection path | route set with respect to the path | route network formed in the 1st main surface of the protection member 3. FIG.

  In the third step, the crossing position of the end of the base portion 31 and the electric wire 2 is set as a fixed position P, and the electric wire 2 is fixed to the protective member 3 at the fixed position P (lower stage in FIG. 3). ). As an aspect which fixes the electric wire 2 to the protection member 3, any of the following aspects can be employ | adopted, for example.

  For example, the electric wire 2 can be fixed to the protective member 3 by inserting a band through a through hole formed in the base portion 31 and fastening the electric wire 2 with the band.

  Further, for example, a notch is formed at a crossing position between the wall standing up around the base portion 31 and the electric wire 2, and the electric wire 2 is inserted into the notch, and the electric wire 2 is inserted into the wall at the notch. You may fix the electric wire 2 to the protection member 3 by fixing with respect to a part. For example, a tape spatula can be used to fix the electric wire 2 at the notch. That is, a tape spatula extending in a tongue shape is formed in the notch, and the electric wire 2 can be fixed to the tape spatula (for example, fixed by wrapping with a tape).

  Further, for fixing the electric wire 2 at the notch, for example, a part that catches on the notch may be used. That is, it is possible to fix the electric wire 2 by attaching in advance to the electric wire 2 a component that catches the notch, and hooking the component on the notch. Here, the hooking part is, for example, a rectangular parallelepiped part in which a through-hole through which an electric wire is inserted is formed near the center, and is configured by a resin molded product in which grooves that engage with the notch portions are formed on both side surfaces. can do. Moreover, it can also comprise a rubber band. When a rubber band is used as a hooking part, a pair of rubber bands are wound around the electric wire 2 with a space between them, and the electric wire 2 is inserted into the notch and the wall portion is sandwiched between the pair of rubber bands. Thus, the electric wire 2 can be fixed to the wall portion at the notch portion.

  Moreover, you may use an adhesive agent for fixation of the electric wire 2 in a notch part, for example. That is, you may fix the electric wire 2 by filling an adhesive between a notch part and the electric wire 2 penetrated here.

  The electric wire 1 with a protective member can be obtained through the above steps. In addition, when fixing the obtained electric wire 1 with a protective member to an external member (for example, a vehicle body panel), as shown in FIG. 4, it is for fixing to the through-hole 33 for fixing component attachment formed in the protective member 3. This part (clamp) 9 may be inserted and inserted, and the fixing part 9 may be attached to the external member 90. Thereby, the electric wire 1 with a protective member can be easily fixed at a fixed position of a vehicle or the like.

  In a state of being fixed at a fixed position of a vehicle or the like, the electric wire 2 included in the electric wire 1 with a protective member is sandwiched between the external member 90 and the protective member 3 in a state where the electric wire 2 with the protective member is regulated to a predetermined laying shape. It protects so that the contact with the part of this may be suppressed. Thereby, the situation where the electric wire 2 contacts and damages another part and a noise is avoided.

<3. Effect>
According to the above embodiment, the protective member 3 is formed with a route network capable of selecting a plurality of routes, and arranged in a state along the selected route set for the route network. Since 2 can be regulated to a predetermined shape, the burden on the assembly of the electric wire 2 is greatly reduced.

  Moreover, since the electric wire 2 can be regulated to different shapes only by changing the route to be selected, various assembly shapes can be flexibly handled. For example, even when the route of the electric wire 2 is changed, the branch position is changed, etc., the change can be dealt with only by selecting another route for the route network formed in the protection member 3.

  Furthermore, the extra length of the electric wire 2 can be absorbed in the electric wire 1 with a protective member according to the route selection mode. For example, the extra length of the electric wire 2 can be absorbed in the electric wire 1 with a protective member by selecting a meandering path.

  Moreover, since the electric wire 2 can be assembled by a simple operation, the operation can be automated.

  Furthermore, since a drawing board, a jig, and the like that are conventionally required in the operation of regulating the electric wire 2 to a predetermined shape are not required, the cost for assembling the electric wire can be reduced. Moreover, since the tape etc. which were conventionally required in order to keep the electric wire 2 in the defined shape become unnecessary, the cost concerning manufacture of an electric wire can also be reduced.

  Moreover, since the process of restricting the electric wire 2 to a predetermined shape and the process of attaching a member for protecting the electric wire 2 to the electric wire 2 are performed at the same time, it also takes the assembly of the electric wire 2 in this respect. The burden is reduced.

It shall be in a fixed state. Specifically, first, the first main surface of the cover member 4 (the surface from which the protrusion 42 protrudes) is made to face the first main surface of the protective member 3 (the surface from which the protrusion 32 protrudes). The cover member 4 is brought close to the protection member 3 so that the entire first main surface of the protection member 3 is covered with the entire first main surface, and the electric wire 2 is interposed between the protection member 3 and the cover member 4. Insert (top of FIG. 7). As described above, the protrusions 42 are formed on the first main surface of the cover member 4 at positions corresponding to the protrusions 32 formed on the first main surface of the protection member 3. Therefore, when the first main surface of the cover member 4 is brought closer to the first main surface of the protection member 3, the tips of the projections 32 of the protection member 3 and the tips of the projections 42 of the cover member 4 come into contact with each other. It becomes a state.
