By the way, some network systems installed in vehicles have a centralized control architecture that is controlled by a control box such as an electrical infrastructure box, a domain controller, or a zone ECU.

In such an in-vehicle network system, there are cases where trunk lines of various variations with different cross-sectional shapes, such as thick bundles of wires connecting upper control boxes and slightly thick bundles of wires connecting upper control boxes and lower control boxes, are routed on the same route. For this reason, in areas where trunk lines are routed on the same route, protectors must be designed and manufactured for each of the various trunk line variations, resulting in increased costs.

In addition, when various variations of main lines are bundled randomly, they may cross or overlap along the route, resulting in an insufficient length for the main lines. This requires a large line length crossover compared to the length of the route, which increases material costs. Also, if a large line length tolerance results in excess length in the main lines, this excess length must be pushed into the protector to be accommodated, making the routing process more cumbersome.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a wiring harness arrangement structure that enables multiple main wires to be easily arranged while suppressing costs.

In order to achieve the above-mentioned object, the wiring harness arrangement structure according to the present invention is characterized by the following (1) to ( 5 ).
(1) A wiring structure for a wire harness that is routed along a wiring path in a body panel of a vehicle, comprising:
The wire harness includes:
A trunk line in which multiple cables are integrated with resin,
a cylindrical protector formed in a straight line and attached so as to cover an outer periphery of the trunk line;
Equipped with
The protector comprises:
The connector is formed in an elongated shape, has a rectangular cross-sectional shape having an insertion hole, and has four side surfaces.
Among the four side surfaces, a first side surface and a second side surface adjacent to each other are each provided with a plurality of engaging protrusions at regular intervals, and a third side surface and a fourth side surface adjacent to each other other than the first side surface and the second side surface are each provided with a plurality of engaging recesses at the same intervals as the engaging protrusions,
The plurality of trunk lines are integrated by fitting the engaging protrusions of the protector into the engaging recesses, and are routed along a linear routing path in the body panel ,
The protectors include a first protector, a second protector, a third protector, and a fourth protector,
For each of the first to fourth protectors, a length in a width direction perpendicular to a longitudinal direction is greater than a length in a height direction perpendicular to the longitudinal direction,
a width direction length of the second protector is equal to a width direction length of the first protector, and a height direction length of the second protector is smaller than a height direction length of the first protector;
The third protector has a width direction length equal to a height direction length of the first protector,
The width of the fourth protector is equal to half the width of the first protector.
Wire harness routing structure.

According to the wiring harness arrangement structure of the above configuration (1), the engaging protrusions and engaging recesses of the protectors attached to each of the multiple main wires are engaged and integrated, so that the multiple main wires can be arranged in parallel along a linear routing path in the body panel. In addition, because a linear cylindrical protector is attached to the main wires, it is not necessary to design and manufacture a protector with a complex shape to match the routing path for each main wire, or to ensure a long excess length. Therefore, multiple main wires can be easily arranged while keeping costs down.

(2) A fixing member is provided which is attached to the protector and fixes the trunk line to which the protector is attached to the body panel,
The fixing member has an engaging protrusion or an engaging recess that can be engaged with the engaging recess or the engaging protrusion of the protector.
The wiring harness arrangement structure according to (1) above.

According to the wiring harness arrangement structure of the above (2), the trunk line to which the protector is attached can be easily fixed to the body panel and routed by engaging the engaging convex or engaging recess of the fixing member with the engaging concave or engaging protruding portion of the protector to fix the fixing member to the body panel.

(3) The trunk line is routed with a portion exposed from the protector bent.
The wiring harness arrangement structure according to (1) or (2) above.

According to the wiring harness arrangement structure of the above (3), the part of the main line exposed from the protector can be easily bent and arranged. In addition, the cable is well protected because the part exposed from the protector is covered with resin.

(4) The trunk line is formed by covering the outer periphery of the plurality of cables with the resin in the length direction by extrusion molding.
The wiring harness arrangement structure according to any one of (1) to (3) above.

According to the wiring harness arrangement structure of the above (4), the multiple cables of the trunk line are covered in resin along their length by extrusion molding, so the cables can be protected along their length. This eliminates the need to protect the parts exposed from the protector with other exterior materials, making it possible to reduce weight and the number of steps required for wiring work.

(5) The protector is divided into a plurality of blocks by providing groove-like constrictions formed in a circumferential direction at equal intervals in a longitudinal direction.
The wiring harness arrangement structure according to any one of (1) to (4) above.

According to the wiring harness arrangement structure of the above (5), the protector can be cut at the constricted portion, and one block can be divided into multiple pieces as the minimum unit for use as needed. This allows the length of the protector to be flexibly set according to the length of the wiring path along which the main wire is routed in a straight line.

According to the present invention, it is possible to provide a wiring harness arrangement structure that can easily arrange a plurality of trunk lines while suppressing costs.

The present invention has been briefly described above. The details of the present invention will become clearer by reading the following description of the embodiment of the invention (hereinafter referred to as "embodiment") with reference to the attached drawings.

Specific embodiments of the present invention are described below with reference to the drawings.

FIG. 1 is a perspective view of a body panel of a vehicle in which a wire harness is routed by the wiring structure according to the present embodiment.
As shown in FIG. 1, the wiring structure of the wire harness according to the present embodiment is, for example, a wiring structure of a wire harness W that is routed in a body panel 1 of a vehicle.

The wire harness W is used, for example, as wiring for an in-vehicle network system with a centralized control architecture controlled by a control box such as an electrical infrastructure box, a domain controller, or a zone ECU.

This wire harness W has a trunk line 10. The trunk lines 10 of this wire harness W include, for example, a thick trunk line connecting the upper control boxes 2 together, a slightly thick trunk line connecting the upper control box 2 and the lower control box 3, and a thin trunk line connecting the lower control boxes 3 together. In this way, the wire harness W has multiple types of trunk lines 10 with different cross-sectional shapes. When the wire harness W is routed to the body panel 1, multiple types of trunk lines 10 with different cross-sectional shapes may be routed on the same route.

The main wire 10 of the wire harness W has a portion that is routed linearly to match the shape of the body panel 1 and a portion that is routed bent. For example, the main wire 10 routed on the floor 4 of the body panel 1 has a straight routing portion 11 that is routed linearly at the top of the floor panel 5 and the cross member 6, and a bent routing portion 12 that is bent at the boundary between the floor panel 5 and the cross member 6, etc.

2 and 3 are perspective and cross-sectional views of a main wire in a wire harness to which a protector is attached.
2 and 3, the wire harness W has a protector 50 attached to a linear wiring portion 11 where the main wire 10 is linearly wired. The protector 50 is made of synthetic resin and is formed into a square tube shape having an insertion hole 51. In the linear wiring portion 11, the main wire 10 is passed through the insertion hole 51 of the protector 50. As a result, the main wire 10 extends linearly by the protector 50, and the outer periphery of the main wire 10 is covered and protected by the protector 50.

The trunk line 10 has, for example, an electric cable 23 in which a conductor 21 is covered with an outer sheath 22, and an optical cable 27 in which an optical fiber 25 is covered with an outer sheath 26, and these electric cables 23 and optical cables 27 are bundled together to form a cable bundle. In this trunk line 10, the electric cables 23 and optical cables 27 are arranged in parallel to form a cable bundle, and are covered all around with resin 29 to integrate them. As the resin 29 that covers the outer periphery of the cable bundle, for example, a resin with excellent flexibility such as urethane is used. This allows the trunk line 10 to be easily bent, particularly in the thickness direction that intersects with the arrangement of the electric cables 23 and optical cables 27.

FIG. 4 is a perspective view showing how a trunk line whose outer periphery is covered with resin is formed by extrusion molding.
4, the cable bundle consisting of the electric cable 23 and the optical cable 27 is inserted into the extrusion opening 31 of the die 30 and is extruded together with the resin 29 from the extrusion opening 31 of the die 30. As a result, the outer periphery of the cable bundle is covered with the resin 29, and the integrated trunk line 10 is extrusion molded.

FIG. 5 is a diagram showing a protector attached to a trunk line, where (a) is a perspective view of the protector, and (b) is a perspective view of the protector separated at a constricted portion.
As shown in Fig. 5(a), the protector 50 is formed in an elongated shape and has a rectangular cross-sectional shape having an insertion hole 51. The protector 50 has groove-shaped constricted portions 52 formed in the circumferential direction on the outer periphery thereof. The constricted portions 52 are formed at equal intervals in the length direction of the protector 50. As a result, the protector 50 is divided into a plurality of blocks 55 by the constricted portions 52. The protector 50 is molded from resin and can be cut at each of the constricted portions 52. As a result, as shown in Fig. 5(b), the protector 50 can be divided into a plurality of blocks 55 as the minimum unit by cutting the protector 50 at the constricted portions 52, and used as needed.

As shown in FIG. 3, the protector 50 has a number of engaging protrusions 61 formed on two adjacent sides out of the multiple sides. In addition, the two sides opposite these two sides have engaging recesses 63 formed into which the engaging protrusions 61 fit and engage. The engaging protrusions 61 and the engaging recesses 63 are arranged at equal intervals in the longitudinal direction of the protector 50 and in the direction perpendicular to the longitudinal direction (width direction or height direction), and are formed at positions corresponding to each other.

As mentioned above, the trunk lines 10 of the wire harness W include a thick trunk line 10 connecting the upper control boxes 2 together, a slightly thicker trunk line 10 connecting the upper control box 2 and the lower control box 3, and a thin trunk line connecting the lower control boxes 3 together. In some cases, multiple types of trunk lines 10 with different cross-sectional shapes are routed on the same route. The various types of trunk lines 10 have different widths and thicknesses depending on the number and outer diameters of the electrical cables 23 and optical cables 27.

FIG. 6 is a diagram showing trunk lines of various cross-sectional shapes, (a) to (d) being cross-sectional views of the trunk lines.
The trunk line 10A shown in Fig. 6(a) is a trunk line with a large cross section composed of a large diameter electric cable 23 and two optical cables 27. The trunk line 10B shown in Fig. 6(b) is a trunk line with an intermediate cross section composed of two electric cables 23 and two optical cables 27 with a medium outer diameter. The trunk line 10C shown in Fig. 6(c) is a trunk line with a small cross section composed of two small diameter electric cables 23 and two optical cables 27. The trunk line 10D shown in Fig. 6(d) is a trunk line with a very small cross section composed of two small diameter electric cables 23 and two small diameter optical cables 27. Thus, the trunk lines 10 include trunk lines 10A to 10D having various cross-sectional shapes each having a different width and thickness.

The protector 50 is compatible with the various trunk lines 10A to 10D, which have different cross-sectional shapes as described above, and is available in cross-sectional shapes that allow these trunk lines 10A to 10D to be inserted therethrough.

FIG. 7 shows protectors to be attached to trunk lines having various cross-sectional shapes, (a) to (d) being front views of the protectors.
The protector 50A shown in Fig. 7(a) is a large protector having an insertion hole 51 through which the main wire 10A with a large cross section can be inserted. The protector 50B shown in Fig. 7(b) is a medium-sized protector having an insertion hole 51 through which the main wire 10B with an intermediate cross section can be inserted. The protector 50C shown in Fig. 7(c) is a small protector having an insertion hole 51 through which the main wire 10C with a small cross section can be inserted. The protector 50D shown in Fig. 7(d) is an extremely small protector having an insertion hole 51 through which the main wire 10D with an extremely small cross section can be inserted.

The large protector 50A, the medium protector 50B, and the small protector 50C have multiple engaging protrusions 61 formed on two adjacent side surfaces, and engaging recesses 63 formed on the two side surfaces opposite these two side surfaces. In addition, the very small protector 50D has multiple engaging protrusions 61 formed on one of the multiple side surfaces, and engaging recesses 63 formed on the side surface opposite this one side surface.

When multiple types of main wires 10A-10D with different cross-sectional shapes are arranged in the same route in the straight wiring section 11 in the wire harness W equipped with the protector 50, the protectors 50A-50D attached to the respective main wires 10A-10D are assembled together and arranged.

Next, an example of a combination in which a plurality of types of trunk lines 10 having different cross-sectional shapes are routed on the same route in the straight-line routing section 11 will be described.
FIG. 8 shows a combination of protectors when various types of trunk lines are routed along the same route, and (a) to (c) are front views of protectors assembled together.

When a large cross-section main line 10A and an interrupted cross-section main line 10B are routed on the same route, a large protector 50A for the main line 10A and a medium-sized protector 50B for the main line 10B are assembled together and routed. As shown in FIG. 8(a), for example, a medium-sized protector 50B is placed on top of the large protector 50A, and the engaging protrusion 61 of the protector 50A is fitted into the engaging recess 63 of the protector 50B to engage them. Then, these protectors 50A and 50B are assembled in an overlapping state, and the large cross-section main line 10A and the interrupted cross-section main line 10B can be routed on the same route.

When a large cross-section main line 10A and a small cross-section main line 10C are routed on the same route, the large protector 50A of the main line 10A and the small protector 50C of the main line 10C are assembled together and routed. As shown in FIG. 8(b), for example, the small protector 50C is placed along the side of the large protector 50A, and the engaging protrusion 61 of the protector 50A is fitted into the engaging recess 63 of the protector 50C to engage them. Then, these protectors 50A and 50C are assembled adjacent to each other, and the large cross-section main line 10A and the small cross-section main line 10C can be routed on the same route.

When a large cross-section trunk line 10A and two very small cross-section trunk lines 10D are routed on the same route, the large protector 50A of the trunk line 10A and the very small protectors 50D of the two trunk lines 10D are assembled together and routed. As shown in FIG. 8(c), for example, the very small protector 50D is stacked side by side on top of the large protector 50A, and the engaging protrusions 61 of the protector 50A are fitted into the engaging recesses 63 of the protectors 50D to engage them. Then, the two protectors 50D are assembled to the protector 50A in a stacked state, and the large cross-section trunk line 10A and the two very small cross-section trunk lines 10D can be routed on the same route.

Figure 9 is a perspective view of a fixing member that fixes the main line with the protector attached to the body panel. Figure 10 is a diagram explaining how the main line is fixed to the body panel by the fixing member, where (a) is a side view of the fixing member before attachment to the protector, and (b) is a side view of the fixing member after attachment to the protector.

As shown in FIG. 9, the main line 10 with the protector 50 attached is fixed to the body panel 1 by a fixing member 80 that is attached to the 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 base. The fixing member 80 is attached to the body panel 1 by inserting the locking portion 81 into a fixing hole 1a formed in the body panel 1. When the locking portion 81 of the fixing member 80 is inserted into the fixing hole 1a, the base of the locking portion 81 locks the edge of the fixing hole 1a 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. As a result, the fixing member 80 is fixed to the body panel 1 without rattling.

As shown in FIG. 10(a), the fixing portion 82 of the fixing member 80 is formed in a plate shape, and a plurality of engaging protrusions 84 are formed on its upper surface. These engaging protrusions 84 are arranged at the same intervals as the engaging recesses 63 of the protector 50. As shown in FIG. 10(b), the fixing member 80 is attached to the protector 50 by fitting the engaging protrusions 84 formed on the fixing portion 82 into the engaging recesses 63 of the protector 50 to engage with each other.

In this way, the main line 10 equipped with the protector 50 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.

The main wire 10 of the wire harness W is routed in the straight wiring section 11 at the portion where the protector 50 is attached, and in the portion exposed from the protector 50 at the bent wiring section 12 (see FIG. 1). At this time, the portion of the main wire 10 exposed from the protector 50 is covered with the highly flexible resin 29, so that it can be easily bent and routed according to the routing path.

As described above, according to the wiring structure of the wire harness W of this embodiment, the engaging protrusions 61 and engaging recesses 63 of the protectors 50 attached to each of the multiple main wires 10 are engaged and integrated, so that the multiple main wires 10 can be wired in parallel along the straight wiring section 11 in the body panel 1. In addition, since the linear cylindrical protectors 50 are attached to the main wires 10, it is no longer necessary to design and manufacture a protector with a complex shape that matches the wiring route for each main wire, or to ensure a long excess length. Therefore, it is possible to easily wire the multiple main wires 10 while keeping costs down.

The fixing member 80 that fixes the protector 50 attached to the main line 10 to the body panel 1 has an engaging protrusion 84 that can engage with the engaging recess 63 of the protector 50. Therefore, by engaging the engaging protrusion 84 of the fixing member 80 with the engaging recess 63 of the protector 50 to fix the fixing member 80 to the body panel 1, the main line 10 to which the protector 50 is attached can be easily fixed and routed to the body panel 1.

The fixing member 80 may have an engagement recess in the fixing portion 82 into which the engagement protrusion 61 of the protector 50 fits. In this case, the fixing member 80 is attached to the protector 50 by fitting the engagement protrusion 61 of the protector 50 into the engagement recess formed in the fixing portion 82 of the fixing member 80 and engaging them with each other.

In addition, in the wiring structure of the wire harness W according to this embodiment, the portion of the trunk line 10 exposed from the protector 50 can be easily bent for wiring. Moreover, the electric cable 23 and the optical cable 27 are covered with the resin 29 even in the portion exposed from the protector 50, so that the electric cable 23 and the optical cable 27 can be well protected.

In addition, the trunk line 10 is coated with resin 29 along the length of the outer periphery of the electric cable 23 and the optical cable 27 by extrusion molding, so that the electric cable 23 and the optical cable 27 can be protected along the length. This eliminates the need to protect the parts exposed from the protector 50 with other exterior materials, etc., and reduces the weight and the labor required for the installation work.

The protector 50 is divided into a number of blocks 55 by groove-like constrictions 52 formed around the circumference and spaced at equal intervals along the length. Therefore, by cutting the protector 50 at the constrictions 52, one block 55 can be used as the smallest unit and divided into a number of blocks as needed. This allows the length of the protector 50 to be flexibly set according to the length of the wiring path along which the trunk line 10 is routed in a straight line.

The present invention is not limited to the above-described embodiment, 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 as long as they can achieve the present invention, and are not limited.

For example, in the above embodiment, the engaging protrusions 61 and the engaging recesses 63 are arranged at equal intervals along the length of the protector 50 and in a direction perpendicular to the length (width or height), but the intervals along the length and in the direction perpendicular to the length may be different.
