[0010] <Embodiment> Hereinafter, a wire harness according to an embodiment of the present invention will be described with reference to the drawings. The wire harness 10 shown in Figure 1 has a number of electric wires 11 and a cover member 20 that flatten and clamps each electric wire 11 along the radial direction. The electric wires 11 are cylindrical in shape with a conductor core covered by an insulating sheath. The cover member 20 includes a first cover 30 and a second cover 40 that sandwich the multiple electric wires 11 between each other.

[0011] <Cover 1, page 30> As shown in Figures 2 and 3, the first cover 30 has a roughly rectangular plate-shaped first cover body 31, a plurality of partition plates 32 erected from the back surface 31B facing the electric wire 11 toward the second cover 40, and insertion portions 33 protruding from the ends of the partition plates 32. The partition plates 32 are plate-shaped and integrally molded with the first cover body 31. The width direction of the first cover body 31 is oriented along the longitudinal direction of the first cover body 31. The thickness direction of the first cover body 31 is oriented along the width direction D2 which is perpendicular (intersects) with the longitudinal direction of the first cover body 31.

[0012] These partition plates 32 are arranged at predetermined intervals along the longitudinal direction D1 (the longitudinal direction of the electric wire 11) of the first cover body 31. In the present embodiment, the partition plates 32 are provided in a plurality of rows in the longitudinal direction D1 with five partition plates 32 as a set. Five sets of partition plates 32 are provided at predetermined intervals along the width direction D2. As shown in FIG. 3, the insertion portion 33 includes a plate-like main body 35 provided on the upper end surface 34 of the partition plate 32, and arrowhead-shaped locking portions 36, 36 that project from both sides in the thickness direction of the main body 35 and incline toward the tip of the main body 35. The separation dimension G1 (see FIG. 3(C)) between the upper end surface 34 of the partition plate 32 and the open end of the locking portion 36 corresponds to the thickness dimension T1 of the second cover body 41 of the second cover 40 described later.

[0013] As shown in FIG. 4, on the surface 31A of such a first cover body 31 that faces away from each electric wire 11 (see FIG. 1) and the second cover 40, a plurality of first notch grooves 37 and a plurality of third notch grooves 38 are provided. The first notch grooves 37 are substantially V-shaped in cross section and are provided along the longitudinal direction D1 of the first cover body 31. The first notch grooves 37 are provided respectively between the partition plates 32 arranged in the width direction D2. In other words, between two first notch grooves 37, a set of partition plates 32 arranged in the longitudinal direction D1 is disposed.

[0014] The third notch grooves 38 are substantially V-shaped in cross section and are provided along the width direction D2 of the first cover body 31. The third notch grooves 38 are provided respectively between the partition plates 32 arranged in the longitudinal direction D1. In other words, between two third notch grooves 38, a set of partition plates 32 arranged in the width direction D2 is disposed. These first notch grooves 37 and third notch grooves 38 are provided at positions avoiding the arrangement locations of the respective partition plates 32. Therefore, on the surface 31A of the first cover body 31, the first notch grooves 37 and the third notch grooves 38 are provided in a grid pattern.

[0015] <Second Cover 40> As shown in FIG. 2, the second cover 40 has a substantially rectangular plate-shaped second cover body 41 and an insertion hole 42 penetrating the second cover body 41 in the thickness direction. The second cover body 41 has the same planar shape and planar dimensions as the first cover body 31 described above. The insertion hole 42 is formed in a rectangular shape into which the main body 35 and the locking portions 36, 36 of the insertion portion 33 provided in the first cover body 31 can be inserted, and the main body 35 of the insertion portion 33 cannot be pulled out by the locking portions 36, 36. These insertion holes 42 are provided at positions corresponding to the insertion portions 33 provided in the first cover body 31.

[0016] Also, as shown in FIG. 5, the second cover body 41 is provided with a plurality of second notch grooves 47 and a plurality of fourth notch grooves 48 on the back surface 41A facing each electric wire 11 (see FIG. 1) and the second cover 40. The second notch groove 47 has a substantially V-shaped cross section and is provided along the longitudinal direction D1 of the second cover body 41. The second notch grooves 47 are provided between the insertion holes 42 arranged in the width direction D2, respectively. In other words, between two second notch grooves 47, a set of insertion holes 42 arranged in the longitudinal direction D1 is arranged.

[0017] The fourth notch groove 48 has a substantially V-shaped cross section and is provided along the width direction D2 of the second cover body 41. The fourth notch grooves 48 are provided between the insertion holes 42 arranged in the longitudinal direction D1, respectively. In other words, between two fourth notch grooves 48, a set of insertion holes 42 arranged in the width direction D2 is arranged. These second notch grooves 47 and fourth notch grooves 48 are provided at positions avoiding the arrangement locations of the respective partition plates 32. Therefore, the second cover body 41 has the second notch grooves 47 and the fourth notch grooves 48 provided in a grid pattern on the back surface 41A.

[0018] Next, the manufacturing procedure for the wire harness 10 described above will be explained. As shown in Figure 6, multiple electric wires 11 are placed on the back surface 31B of the first cover body 31. Then, as shown in Figure 7, the second cover body 41 is placed over the first cover body 31, and the locking parts 36, 36 provided on the partition plate 32 are locked into the insertion holes 42. In this way, the multiple electric wires 11 are held flat between the first cover body 31 and the second cover body 41. As described above, the distance G1 between the upper end surface 34 of the partition plate 32 and the base end surface of the locking part 36 corresponds to the thickness dimension T1 of the second cover body 41. For this reason, the first cover body 31 and the second cover body 41 are firmly fixed to each other.

[0019] Next, as shown in Figure 8, the ultrasonic crimper 50 is brought into contact with the surface 31A of the first cover body 31. Then, the ultrasonic horn 51 is brought into contact with the surface 41B of the second cover body 41. After that, ultrasonic waves of a predetermined frequency are emitted from the ultrasonic horn 51. As a result, the main body 35 and locking parts 36, 36 of the insertion part 33 and the insertion hole 42 are ultrasonically welded together. In addition, the upper end surface 34 of the partition plate 32 and the back surface 41A of the second cover body 41 are ultrasonically welded together. As a result, the first cover 30 and the second cover 40 are firmly fixed together. Note that this ultrasonic welding process is optional.

[0020] As described above, the wire harness 10, which is provided with the cover member 20, has a first cover body 31 with a plurality of first notches 37 and a plurality of third notches 38. The second cover body 41 has a plurality of second notches 47 and a plurality of fourth notches 48. Therefore, as shown in Figure 9, the first cover body 31 and the second cover body 41 can be deformed into a polygonal shape with the first notches 37, second notches 47 and third notches 38 and fourth notches 48 as boundaries. This allows the cover member 20 to be positioned along the vehicle body B, which is a convex arc surface. In this case, the cover member 20 can be deformed three-dimensionally along the longitudinal direction of the first cover body 31 and the second cover body 41 and in directions perpendicular to the longitudinal direction. It should be noted that the wire harness 10 can also have the cover member 20 positioned along the vehicle body, which is a concave arc surface, and it is also possible to have the cover member 20 positioned along a curved surface with a complex mixture of concave and convex shapes.

[0021] Furthermore, the first cover body 31 and the second cover body 41 are cut along the first notch groove 37, the second notch groove 47, the third notch groove 38, and the fourth notch groove 48 using a tool or the like. Alternatively, the first cover body 31 and the second cover body 41 are repeatedly bent along the first notch groove 37, the second notch groove 47, the third notch groove 38, and the fourth notch groove 48 to cause fatigue fracture. As a result, the first cover body 31 and the second cover body 41 can be formed into any shape and dimensions, as shown in the cover members 20A to 20C in Figures 10(A) to 10(C).

[0022] <Effects of the Embodiment> As described above, according to the wire harness 10 according to the embodiment of the present invention, five partition plates 32 are arranged in a set of five, each arranged at a predetermined interval along the longitudinal direction of the first cover body 31 (the longitudinal direction of the electric wire 11), and five sets of these partition plates are arranged at predetermined intervals along a direction perpendicular (intersecting) to the longitudinal direction of the first cover body 31. Therefore, each electric wire 11 can be held flat along the radial direction between the first cover 30 and the second cover 40. In addition, each electric wire 11 cannot move freely between the first cover 30 and the second cover 40. Accordingly, according to the wire harness 10 according to the embodiment of the present invention, there is no risk of deformation such as the first cover 30 and the second cover 40 bulging, as in the conventional design, and a large number of electric wires 11 can be held flat and stably.

[0023] Furthermore, according to the wire harness 10 according to the embodiment of the present invention, the insertion portion 33 of the first cover body 31 is locked into the insertion hole 42 of the second cover 40. As a result, the first cover 30 and the second cover 40 are firmly fixed, thereby enabling a large number of electric wires 11 to be held flat and stably.

[0024] Furthermore, according to the wire harness 10 according to the embodiment of the present invention, the insertion portion 33, which is the tip of the partition plate 32, and the insertion hole 42 of the second cover body 41 are welded together. This makes it possible to further strengthen the mutual fixation of the first cover 30 and the second cover 40.

[0025] Furthermore, according to the wire harness 10 of the present invention, multiple electric wires 11 that are not fixed to each other are housed between multiple partition plates 32. Therefore, a large number of electric wires 11 can be held flat and stably.

[0026] Furthermore, according to the wire harness 10 according to an embodiment of the present invention, the first cover 30 has a first notch groove 37 in the first cover body 31, and the second cover 40 has a second notch groove 47 in the second cover body 41. Therefore, the first cover body 31 and the second cover body 41 can be deformed into polygonal shapes with the first notch groove 37 and the second notch groove 47 as boundaries. This allows the cover member 20 to be positioned along the vehicle body, which has a convex or concave arc surface. In addition, by cutting the first cover body 31 and the second cover body 41 along the first notch groove 37 and the second notch groove 47, the first cover body 31 and the second cover body 41 can be formed into any shape and dimensions.

[0027] Furthermore, according to the wire harness 10 according to an embodiment of the present invention, the first cover 30 has a third notch groove 38 in the first cover body 31, and the second cover 40 has a fourth notch groove 48 in the second cover body 41. Therefore, the first cover body 31 and the second cover body 41 can be deformed into polygonal shapes using the third notch groove 38 and the fourth notch groove 48 as boundaries. This allows the cover member 20 to be positioned along the vehicle body, which has a convex or concave arc surface. In addition, by cutting the first cover body 31 and the second cover body 41 along the third notch groove 38 and the fourth notch groove 48, the first cover body 31 and the second cover body 41 can be formed into any shape and dimensions.

[0028] <Other forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.

[0029] For example, in the embodiments described above, cover members 20A to 20C were shown as being cut in a rectangular shape using the first notch groove 37, the second notch groove 47, the third notch groove 38, and the fourth notch groove 48 as boundaries, but the invention is not limited to these. Cover members formed in the shape of a C, L, E, F, O, T, etc. by appropriately cutting the first cover body 31 and the second cover body 41 are also included in the present invention.

[0030] Furthermore, in the embodiments described above, the first notch groove 37, the second notch groove 47, the third notch groove 38, and the fourth notch groove 48 were provided in a V-shaped groove, but this is not the only option. The first notch groove 37, the second notch groove 47, the third notch groove 38, and the fourth notch groove 48 can be any groove that allows for easy bending or cutting, and may, for example, be composed of perforations.
