In such an in-vehicle network system, for example, there are various trunk lines with different cross-sectional shapes, such as a thick wire bundle that connects upper control boxes and a somewhat thick wire bundle that connects a higher control box and a lower control box. may be routed on the same route. For this reason, in the portion where trunk lines are laid on the same route, it is necessary to design and manufacture a protector for each trunk line of various variations, resulting in an increase in cost.

In addition, if trunk lines of various variations are bundled at random, the trunk lines may cross or overlap each other in the middle of the wiring route, and the length of the trunk lines may become insufficient. For this reason, it is necessary to secure a large line length intersection of the main line with respect to the length of the wiring route, which increases the material cost. In addition, if the trunk line has an excess length due to a large line length tolerance, the excess length must be pushed into the protector to accommodate it, which complicates the wiring work.

Fig. 10 is a side view at the rear;

As shown in FIG. 9 , trunk line 10 to which protector 50 is attached is fixed to body panel 1 by fixing member 80 assembled to body panel 1 and routed. The fixing member 80 is molded from resin and has a locking portion 81 and a fixing portion 82 . The locking portion 81 is formed in a tapered shape, and a pressing piece 83 is provided at the root portion. The fixing member 80 is assembled to the body panel 1 by inserting the locking portion 81 into the fixing hole 1 a formed in the body panel 1 . When the locking portion 81 of the fixing member 80 is inserted into the fixing hole 1 a , the base of the locking portion 81 locks the edge of the fixing hole 1 a on the back side of the body panel 1 . In this state, the pressing piece 83 is pressed against the body panel 1 and elastically deformed. Thereby, the fixing member 80 is fixed to the body panel 1 without rattling.

Thus, the main line 10 to which the protector 50 is attached can be easily routed to the body panel 1 by attaching the fixing member 80 to the protector 50 and assembling the fixing member 80 to the body panel 1. It's becoming

The trunk line 10 of the wire harness W is routed in the straight wiring portion 11 at the portion where the protector 50 is attached, and is routed in the bent wiring portion 12 at the portion exposed from the protector 50 (see FIG. 1). At this time, since the part of the trunk line 10 exposed from the protector 50 is covered with the resin 29 having excellent flexibility, the trunk line 10 can be easily bent and routed according to the routing route.

As described above, according to the wiring structure of the wire harness W according to the present embodiment, the engaging projections 61 and the engaging recesses 63 of the protectors 50 attached to the respective trunk lines 10 are engaged with each other. These trunk lines 10 can be wired in parallel along the straight wiring portion 11 of the body panel 1 by aligning and integrating them. In addition, since the cylindrical protector 50 formed in a straight line is attached to the main line 10, it is necessary to design and manufacture a protector with a complicated shape that matches the wiring route for each main line, or to secure a long extra length. disappears. Therefore, it is possible to easily route a plurality of trunk lines 10 while suppressing costs.

A fixing member 80 for fixing the protector 50 attached to the main line 10 to the body panel 1 has an engaging convex portion 84 that can be engaged with the engaging concave portion 63 of the protector 50 . Therefore, by engaging the engaging convex portion 84 of the fixing member 80 with the engaging concave portion 63 of the protector 50 and fixing the fixing member 80 to the body panel 1 , the main line 10 to which the protector 50 is attached can be attached to the body panel 1 . Can be easily fixed and routed.

It should be noted that the fixing member 80 may have an engaging concave portion in which the engaging convex portion 61 of the protector 50 is fitted in the fixing portion 82 . In this case, the fixing member 80 is attached to the protector 50 by fitting the engaging projections 61 of the protector 50 into the engaging recesses formed in the fixing portion 82 of the fixing member 80 to engage with each other.

Further, in the wiring structure of the wire harness W according to the present embodiment, the portion of the main line 10 exposed from the protector 50 can be bent to facilitate wiring. Moreover, since the electric cable 23 and the optical cable 27 are covered with the resin 29 even at the portions exposed from the protector 50, the electric cable 23 and the optical cable 27 can be well protected.

In the main line 10, the outer circumferences of the electric cable 23 and the optical cable 27 are coated with the resin 29 in the longitudinal direction by extrusion molding, so that the electric cable 23 and the optical cable 27 can be protected in the longitudinal direction. As a result, there is no need to protect the portion exposed from the protector 50 with another exterior member or the like, so that the weight can be reduced and the man-hours required for wiring work can be reduced.

Further, the protector 50 is partitioned into a plurality of blocks 55 with groove-shaped constricted portions 52 formed over the circumferential direction provided at equal intervals in the longitudinal direction. Therefore, by cutting the protector 50 at the constricted portion 52, one block 55 can be divided into a plurality of pieces as a minimum unit and used. Thereby, the length of the protector 50 can be flexibly set according to the length of the wiring route for linearly wiring the trunk line 10 .

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, location, etc. of each component in the above-described embodiment are arbitrary and not limited as long as the present invention can be achieved.

For example, in the above-described embodiment, the engaging projections 61 and the engaging recesses 63 are arranged at the same intervals in the longitudinal direction of the protector 50 and in the direction (width direction or height direction) perpendicular to the longitudinal direction. However, the longitudinal spacing and the perpendicular spacing may be different.
