  A wire routing structure according to an embodiment of the present invention will be described with reference to FIGS.

  The electric wire routing structure 1 according to the present embodiment includes a plurality of electric wires 3 and 5 having different outer diameters, and a protector 9 disposed in a bent portion 7 where the plurality of electric wires 3 and 5 are bent. .

  In addition, the plurality of electric wires 3 and 5 are arranged in parallel in the protector 9, and the bent portion 7 is bent in a direction orthogonal to the arrangement direction of the plurality of electric wires 3 and 5 in the protector 9. Is provided with a folded portion 11 in which the bent portions 7 of the plurality of electric wires 3 and 5 are arranged.

  And in the folding | returning part 11, the electric wire 3 with the smallest outer diameter among the some electric wires 3 and 5 is arrange | positioned in the inner peripheral side, and the electric wire 5 with the largest outer diameter among the some electric wires 3 and 5 is arranged on the outer peripheral side. Arranged along the outer shape of the folded portion 11.

  The folded portion 11 is arranged in a state where the electric wire 5 having the largest outer diameter among the plurality of electric wires 3 and 5 is bent smaller than the minimum bending radius.

  As shown in FIGS. 1 to 4, the plurality (two in this case) of electric wires 3 and 5 are each configured by bundling a plurality of core wires (not shown) inside. The plurality of electric wires 3 and 5 are set to have different outer diameters.

  The plurality of electric wires 3 and 5 are, for example, electrically connected between a power source and a device or between devices, and are routed to the vehicle body as a set of wire harnesses. In a state where the wire harness is routed in the vehicle body, the plurality of electric wires 3 and 5 are provided with bent portions 7 in order to avoid interference between the plurality of electric wires 3 and 5 and peripheral members mounted on the vehicle body. .

  The bent portion 7 of the plurality of electric wires 3 and 5 is provided with a protector 9 because the bent shape cannot be maintained in a state in which the plurality of electric wires 3 and 5 are routed in the vehicle body. By fixing 9 to the vehicle body by fixing means or the like, the wiring shape of the wire harness with respect to the vehicle body is maintained.

  The protector 9 is made of an insulating material such as synthetic resin, and has a main body portion 13 having a concave cross-sectional shape, and a flat plate shape that is assembled to the opening side of the main body portion 13 via a plurality of locking portions 15. And a cover portion 17 formed. Further, the protector 9 is opened on both sides in the length direction of the plurality of electric wires 3 and 5 in a state where the main body portion 13 and the cover portion 17 are assembled.

  In the protector 9, a plurality of electric wires 3, 5 are arranged in parallel along the height direction (vertical direction) of the main body 13. The bent portions 7 of the plurality of electric wires 3 and 5 arranged in parallel in the vertical direction are directed in the width (length) direction (lateral direction) of the main body 13 which is a direction orthogonal to the height direction of the main body 13. Is bent.

  Thus, by arranging the arrangement direction of the plurality of electric wires 3 and 5 and the bending direction of the bent portion 7 in the protector 9, the protector 9 is not enlarged in the vertical direction or the horizontal direction, The protector 9 can be made compact as a whole. Such a protector 9 is provided with a folded portion 11 in which the bent portions 7 of the plurality of electric wires 3 and 5 are arranged.

  The folded portion 11 is provided with a curved outer shape so that the opening on one side and the opening on the other side of the protector 9 are opened in different directions. The outer shape of the folded portion 11 is such that the electric wire 5 having the largest outer diameter among the plurality of electric wires 3 and 5 is bent smaller than the minimum bending radius (here, twice the outer diameter of the electric wire). 5 is set to be equivalent to the shape of the bent state.

  In such a folded portion 11, the bent portions 7 of the plurality of electric wires 3 and 5 are arranged. Specifically, the electric wire 3 having the smallest outer diameter among the plurality of electric wires 3 and 5 has a small repulsive force with respect to the bending of the electric wire 3, and extends from both ends (opening sides on both sides of the protector 9) to the bent portion 7. Since it can be easily bent even if the length is short, the bent portion 7 is arranged along the shape of the inner peripheral side of the folded portion 11.

  On the other hand, since the electric wire 5 having the largest outer diameter among the plurality of electric wires 3 and 5 has a large repulsive force against the bending of the electric wire 5, the length from the both ends (opening sides on both sides of the protector 9) to the bent portion 7 The length of the wire 5 is set to be easy to bend against the repulsive force of the electric wire 5.

  The bent portion 7 of the electric wire 5 bent in this way is arranged along the outer peripheral side shape of the folded portion 11 having the same outer shape as the bent portion 7 that is set to be easily bent. For this reason, even if the bent part 7 of the rapidly bent electric wire 5 is arranged in the folded part 11, the burden on the folded part 11 due to the repulsive force of the electric wire 5 can be reduced.

  By arranging the bent portions 7 of the plurality of electric wires 3 and 5 having different outer diameters in the folded portion 11 in this manner, the plurality of electric wires 3 and 5, particularly the electric wire 5 having the largest outer diameter is suddenly bent. Even if it is a routing route, the several electric wires 3 and 5 can be routed, suppressing the enlargement of the protector 9. FIG.

  In addition, in the routing route that requires rapid bending, when the electric wire 5 having the largest outer diameter is not bent at the folded portion 11, the length from both ends of the electric wire 5 to the bent portion 7 is shortened. There is a possibility that the protector 9 will be enlarged due to the bent state as indicated by the virtual line.

  For this reason, like the electric wire routing structure 1 according to the present embodiment, it is necessary to provide the folded portion 11 in the protector 9 and arrange the bent portion 7 of the electric wire 5 along the folded portion 11. It is very effective in the routing route.

  In such a wire routing structure 1, the plurality of wires 3, 5 are arranged in parallel in the protector 9, and the bent portion 7 is directed in a direction orthogonal to the arrangement direction of the plurality of wires 3, 5 in the protector 9. Since it is bent, the protector 9 is enlarged to a size in which the arrangement direction of the electric wires 3 and 5 and the bending direction of the bent portion 7 are combined toward the arrangement direction of the electric wires 3 and 5 and the bending direction of the bent portion 7. There is no such thing, and the influence from the routing route of electric wires 3 and 5 can be controlled.

  Further, the folded portion 11 of the protector 9 is provided with the electric wire 3 having the smallest outer diameter among the plurality of electric wires 3 and 5 on the inner peripheral side, and has the largest outer diameter among the plural electric wires 3 and 5 on the outer peripheral side. Since the electric wire 5 is arranged along the outer shape of the turned-up portion 11, the outer shape in the bending direction of the protector 9 may be matched with the bent portion 7 of the electric wire 5 having the largest outer diameter. However, the enlargement of the protector 9 can be suppressed.

  Therefore, in such a wire routing structure 1, it is possible to suppress an increase in the size of the protector 9 and to suppress the influence from the routing route of the wires 3 and 5.

  Further, since the folded portion 11 is arranged in a state where the electric wire 5 having the largest outer diameter among the plurality of electric wires 3 and 5 is bent smaller than the minimum bending radius, the protector 9 with respect to the suddenly bent wiring path. The plurality of electric wires 3 and 5 can be routed while suppressing the increase in size.

  In addition, in the electric wire routing structure according to the present embodiment, there are two electric wires having different outer diameters, but the present invention is not limited to this, and there may be two or more electric wires having different outer diameters. .

  Moreover, the arrangement direction of the electric wire is the height direction of the protector, and the bending direction of the bent portion is the width (length) direction of the protector, but not limited to this, the arrangement direction of the electric wire and the bent direction of the bent portion are The arrangement direction of the electric wire, the bending direction of the bent portion, and the shape of the protector may be set in consideration of interference with the wiring route of the electric wire and peripheral members.
