Here, the several electric wire 1 is arrange | positioned 1 each in each groove part 32, and is located in a line along the parallel direction P in the state located in the bottom side of each groove part 32 (refer FIG. 3). The flattening target portions 3 of the plurality of electric wires 1 extend in parallel between the connector C and the electric wire flattening member 20. For example, the electric wire flattening member 20 is 30 mm on the electric wire flattening member 20 side with respect to the flattening target portion 3 at the position where the work allowance for terminal attachment of 80 mm from the distal end portion of the connector C in the plurality of electric wires 1 is secured. It is good to set to the position which leaves an interval. In addition, the attachment position of the electric wire flattening member 20 is good to consider the dispersion | variation in the length of the some electric wire 1, the attachment tolerance of the electric wire flattening member 20, etc., and to set it. In addition, the binding material winding portion 40 and the plurality of electric wires 1 extending along the binding material winding portion 40 are bundled together by the binding material 70 between the pair of electric wire support portions 30. It is maintained at a position on the bottom side of the groove portion 32 of the support portion 30 and in contact with the one main surface 42 of the binding material winding portion 40 (see FIG. 3).

  The flattened structure 10 of the wire harness is manufactured on the assembly drawing board 80 in the assembly process of the wire harness. That is, when the plurality of electric wires 1 are wired on the assembly drawing board 80 in a wiring form, the plurality of electric wires 1 are set on the electric wire flattening member 20 and flattened. Here, the electric wire flattening member 20 may be supported on the assembly drawing board 80 using a dedicated support jig 82. FIG. 6 shows an example of the support jig 82. For convenience of explanation, the support jig 82 will be described.

Here, the pair of support portions 84 are formed in the same shape. The receiving portion 85 is a portion on which one end portion in the parallel direction P of the electric wire flattening member 20 is placed. The receiving portion 85 has a rectangular bottom portion and continuous side wall portions erected on three sides thereof. That is, the receiving portion 85 supports the one end side in the parallel direction P of the electric wire flattening member 20 by the bottom portion, and restricts movement to the one side in the parallel direction P of the electric wire flattening member 20 and both sides in the wiring direction A by the side wall portion. Moreover, the receiving part 85 has a slit part 86 in which the convex part 34 of the electric wire flattening member 20 can be disposed. The column portion 87 is a portion that supports the receiving portion 85 on the assembly drawing plate 80, and is formed so that the base end portion can be fixed by being screwed to the assembly drawing plate 80, and the distal end portion is the receiving portion 85. It continues to the bottom.

  The support jig 82 is configured by fixing a pair of support portions 84 on the assembly drawing board 80 facing each other. In the following description, it is assumed that the wire flattening member 20 is supported by the support jig 82. That is, the electric wire flattening member 20 is supported by the pair of support portions 84 with both end portions in the parallel direction P being placed on the bottom of each receiving portion 85. Here, since the flattening target portion 3 in the plurality of electric wires 1 is a portion extending from the connector C, the support jig 82 is provided at a position facing the support position of the connector C.

  Hereinafter, the manufacturing process of the flattened structure part 10 of a wire harness is demonstrated.

  First, the plurality of wires 1 are respectively disposed in the plurality of grooves 32 in the pair of wire support portions 30 of the wire flattening member 20 supported by the support jig 82 (step (a)). Here, a plurality of electric wires 1 are arranged one by one with respect to each groove 32 so as to be arranged in the order in which they are connected to the connector C. Since the plurality of electric wires 1 are disposed in the plurality of grooves 32 in the order in which they are connected to the connector C, the support position of the connector C and the position of the support jig 82 are set as close as possible.

  Next, the electric wire flattening member 20 is taken out from the support jig 82 and moved to a position to the side of the flattening target portion 3 in the plurality of electric wires 1 (see step (b), FIG. 7). That is, the electric wire flattening member 20 is positioned at the side of the flattening target portion 3 from the position supported by the support jig 82 when the plurality of electric wires 1 are disposed in the respective groove portions 32 in the step (a). Moved to.

  Further, in the step (b), in order to release the slack caused by the variation in the length of each electric wire 1 from between the connector C and the electric wire flattening member 20, the electric wire 1 is removed from the electric wire flattening member 20. Sometimes slide.

  And the several electric wire 1 is bundled with the binding material winding part 40 in the state which put the several electric wire 1 along the binding material winding part 40 (process (c)). More specifically, the adhesive tape as the binding material 70 is an axis along the wiring direction A with respect to the whole of the binding material winding portion 40 and the plurality of electric wires 1 extending along the binding material winding portion 40. Wrap around. Thereby, the some electric wire 1 and the electric wire flat member 20 are maintained in the fixed state.

  Through the above steps, the flattening target portion 3 in the plurality of electric wires 1 between the connector C as the terminal member of the plurality of electric wires 1 and the electric wire flattening member 20 is maintained in a flat shape. But the connector C and the electric wire flattening member 20 shall exist in the attitude | position in which the some electric wire 1 extended between them is located on a plane (it does not twist at least). Thereby, the flattening object part 3 of the some electric wire 1 can be wired also in a narrow space.

  Up to now, the electric wire support portion 30 in which the four groove portions 32 are formed has been described, but the number of the groove portions 32 may be determined according to the number of the electric wires 1 in the flattening target portion 3 of the plurality of electric wires 1. .

  So far, the example in which the electric wires 1 are arranged one by one with respect to the plurality of groove portions 32 of the electric wire support portion 30 has been described, but it is only necessary to maintain the plural electric wires 1 in a flat shape in at least one direction. You may arrange | position the some electric wire 1 in piles with respect to the groove part 32 (refer FIG. 8). From the viewpoint of reducing the thickness dimension of the flattened portions of the plurality of electric wires 1, up to two stages are preferable, but from the viewpoint of supporting in a flat shape, it may be set to three or more stages depending on the arrangement space. This configuration is effective when, for example, the terminal members such as the connector C are connected in two rows. In addition, the depth dimension of the groove part 32 in this case should just be set deep according to the number of the electric wires 1 arrange | positioned in piles.

  Moreover, you may arrange | position the some electric wire 1 in each groove part 32 of the some electric wire flattening member 20 in the state which connected the some electric wire flattening member 20. FIG. FIG. 5 shows a flattened structure portion 110 of a wire harness configured by connecting two electric wire flattening members 20. In this case, the support jig 82 is used in which the distance is adjusted by changing the fixing position of the pair of support portions 84 with respect to the assembly drawing plate 80 corresponding to the dimension in the parallel direction P of the connected electric wire flattening members 20. What is necessary is just to support the edge part side part of the electric wire flattening member 20 located in the parallel direction P both ends among the some electric wire flattening members 20 connected. According to this configuration, more electric wires 1 can be collectively maintained in a flat shape.

  Moreover, the groove part 32 of the electric wire flattening member 20 is not restricted to the case where it forms in a U shape in front view. That is, the groove part 320 which has the electric wire accommodating part 321 which has an internal space larger than the diameter of the electric wire 1 in the bottom side, and has the retaining part 322 smaller than the diameter of the electric wire 1 in the opening side may be employ | adopted. The groove 320 is also preferably formed so that the inner periphery thereof is smooth along the wiring direction A. Then, while the electric wire 1 is disposed in the electric wire housing portion 321 of the groove portion 320, the electric wire 1 is supported so as to be slidable in the wiring direction A within the electric wire housing portion 321 while being prevented from coming out of the opening by the retaining portion 322. Is done. FIG. 9 shows an electric wire flattening member 120 having an electric wire support portion 130 in which the groove portion 320 is formed.

  Moreover, the convex part 34 and the recessed part 36 which concern on the connection of the electric wire flattening member 20 are not restricted to the combination of the shape mentioned above. For example, it may be a combination of a convex part in which a claw part protruding to the outer peripheral side at the tip part and a concave part having an internal space in which the claw part can be disposed.

  Further, the electric wire flattening member 20 is not limited to the configuration having the pair of electric wire support portions 30. That is, the electric wire flattening member 20 may have a configuration including one electric wire support portion 30 and a binding material winding portion 40 connected to the side thereof.

  FIG. 10 shows a flattened structure portion 210 of the wire harness in which the wire flattening member 20 is provided in a pair with the flattening target portions 3 in the plurality of electric wires 1 interposed therebetween. That is, each electric wire flattening member 20 is attached to both sides of the flattening target portion 3 in the plurality of electric wires 1, and the portion extending between the pair of electric wire flattening members 20 is maintained in a flat shape. The

  According to the electric wire flattening member 20 according to the embodiment, from the electric wire support portion 30 and the electric wire support portion 30 in which a plurality of groove portions 32 in which the electric wire 1 can be slidably moved along the wiring direction A are formed in parallel.

In the flattening structure portion 10 of the wire harness, the electric wire flattening member 20 supports the side portions of the flattening target portion 3 in the plurality of electric wires 1, and the plural electric wires 1 respectively have a plurality of electric wire support portions 30. In addition to being disposed in the groove portion 32, it is bundled together with the binding material winding portion 40 by the binding material 70 along the binding material winding portion 40. For this reason, the flattening target portions 3 extending to the side of the electric wire flattening member 20 among the plurality of electric wires 1 are arranged in parallel along the wiring direction A and maintained in a flat shape, so that the space is narrow. Can also be routed. Moreover, in the manufacturing method of the flattened structure part 10 of a wire harness, before winding the binding material 70, the wire flattening member 20 is slid and moved to the wiring direction A with respect to the some electric wire 1, and wire harness assembly is carried out. The position of the flattened portion can be adjusted from the alignment state of the plurality of electric wires 1 in the process. Further, even when slackening occurs in the flattening target portion 3 due to variations in the length of the plurality of electric wires 1, the length of the slackening is determined between the connector C (or the electric wire flattening member 20) and the electric wire flattening member 20. It is possible to escape from the gap, and a more stable flat shape can be obtained.

  In addition, since the groove portion 32 is formed in a U shape wider than the diameter of the electric wire 1 in a front view, and the inner peripheral portion thereof is formed smoothly along the wiring direction A, the electric wire 1 is arranged in the groove portion 32. It is easy to install and it is easy to slide the electric wire 1 disposed in the groove 32 in the wiring direction A.

  Further, since a pair of wire support portions 30 are provided and the binding material winding portion 40 is connected in a posture in which the pair of wire support portions 30 are opposed to the wiring direction A, each wire disposed in the plurality of groove portions 32 is provided. 1 can be more reliably aligned along the wiring direction A, and the binding material 70 is wound from the binding material winding portion 40 in the wiring direction A in a state where the binding material 70 is wound around the binding material winding portion 40. It is possible to suppress detachment.

  Further, since the binding material winding portion 40 is formed in a shape in which both side end portions 44 are curved in a concave shape and the intermediate portion in the wiring direction A is set to be narrow, the binding material winding portion 40 is wound around the binding material winding portion 40. The material 70 can be prevented from shifting in the wiring direction A.

  Moreover, the electric wire support part 30 is a convex part 34 that protrudes in one direction from one end part in the parallel direction P, and a concave part 36 that is formed in the other end part in the parallel direction P and can be fitted to the convex part 34 of the other electric wire support part 30.
