[0040] Hereinafter, the embodiments of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiments. In addition, the constituent elements of the following embodiments include elements that can be easily replaced by those skilled in the art, or substantially the same elements.

[0041] [Implementation Method]

[0042] Figure 1 The wire harness 1 shown is applied to a vehicle, and is used for power supply and signal communication by connecting various devices installed in the vehicle. The wire harness 1 of the present embodiment uses a flexible flat wiring material 10 as a wiring material, and the flat wiring material 10 is wired in an installation target portion 100, and the installation target portion 100 constitutes at least a part of the vehicle body panel. In addition, the wire harness 1 realizes a structure that can improve assemblability by forming the mounting hole portion 12 provided in the flat wiring material 10 to be larger than the mounting protrusion portion 110 provided in the installation target portion 100. Hereinafter, referring to Figure 1 to Figure 7 , the structure of the wiring harness 1 is described in detail.

[0043] The vehicle body panel referred to herein is a structural member (frame member) of the vehicle, such as a dash panel, a door panel, a roof panel, or the like.

[0044] In the following description, the first direction among the first direction, the second direction, and the third direction that intersect each other is referred to as the "length direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "thickness direction Z". Here, the length direction X, the width direction Y, and the thickness direction Z are orthogonal to each other. In addition, the length direction X is typically equivalent to the long side direction (extension direction) of the flat wiring material 10, and the width direction Y is typically equivalent to the short side direction of the flat wiring material 10. Figures 1 to 7 The XY directions shown correspond to the plane directions of the flat wiring member 10. In addition, each direction used in the following description is described as a direction in a state where the wire harness 1 is attached to the attachment target portion 100 unless otherwise specified.

[0045] like Figure 1 As shown, the wire harness 1 includes: a flat wiring member 10 having flexibility; a first connector 20 provided at an end 10 a of the flat wiring member 10 ; and a second connector 30 provided on a surface 11 of the flat wiring member 10 .

[0046] The flat wiring material 10 is a wiring material constituting the wiring harness 1. The flat wiring material 10 of the present embodiment is a flexible printed circuit (FPC, Flexible Printed Circuits). The flat wiring material 10 includes a base film, a wiring pattern and a covering layer. In addition, the base film mentioned here is a substrate having excellent flexibility and defining the overall shape of the flat wiring material 10. The base film is formed of, for example, a polyimide resin having excellent heat resistance. In addition, the wiring pattern is stacked on the surface of the base film to form a plurality of conductor circuit portions (pattern layers). The wiring pattern is formed of, for example, a conductive metal material such as copper foil, and is printed on the surface of the base film as a printed circuit body. In addition, the covering layer is stacked on the entire surface of the base film via an adhesive not shown in the figure, and functions as a protective layer for protecting the conductor circuit portion of the wiring pattern.

[0047] In addition, if Figure 1 As shown, the flat wiring material 10 is formed into a thin plate shape, extending along the length direction X and the width direction Y, and formed into a generally rectangular shape with the thickness direction Z being the plate thickness direction. In addition, the flat wiring material 10 of the present embodiment is formed to include a main surface 11a and an end surface 11b, the main surface 11a is formed along the length direction X and the width direction Y and is configured to have a larger area than other surfaces, and the end surface 11b is formed along the thickness direction Z orthogonal to the main surface 11a and is configured to have a smaller area than other surfaces. In the flat wiring material 10 of the present embodiment, the second connector 30 is provided on the main surface 11a among the surfaces 11 of the flat wiring material 10 (see Figure 2 ).

[0048] A pair of first connectors 20 are provided at intervals and are connection components provided at both ends 10a of the flat wiring material 10 in the length direction X. The first connectors 20 are electrically connected to the conductor circuit portion (pattern layer) of the flat wiring material 10. In addition, the first connectors 20 are connected to the first connection objects 200 (see FIG. 1 ) which are fixed in advance to the installation object portion 100. Figures 3 to 5 ), thereby enabling the flat wiring material 10 and the first connection object 200 to be electrically connected to each other.

[0049] The first connection object 200 is, for example, a control device (ECU: Electronic Control Unit), and a first connection object side connector that can be mated with the first connector 20 is provided in the device. Therefore, the first connector 20 is mated with the first connection object side connector in a direction intersecting the thickness direction Z of the flat wiring material 10 (in this embodiment, the length direction X of the flat wiring material 10) as the mating direction, thereby electrically connecting the first connection object 200 and the flat wiring material 10. By making a pair of first connectors 20 respectively mated with the first connection object side connector, the flat wiring material 10 can electrically connect the control devices to each other. In addition, the first connection object 200 can also be a device other than the ECU, and various changes can be made according to the specifications of the wiring harness 1.

[0050] The second connector 30 is provided with at least one, and is a connecting member provided between a pair of first connectors 20. The second connector 30 is electrically connected to the conductor circuit portion (pattern layer) of the flat wiring material 10. Figures 3 to 5 ) is fixed to the mounting target portion 100, the first connector 20 is connected to the second connection target 300, thereby enabling the flat wiring material 10 and the second connection target 300 to be electrically connected.

[0051] The second connection object 300 is, for example, an auxiliary device (auxiliary equipment) for operating the main engine, and in this embodiment, a control unit (ECU). Figure 2 As shown, in this device, a second connection object side connector 310 that can be mated with the second connector 30 is provided. Therefore, the second connector 30 is mated with the second connection object side connector 310 with the thickness direction Z of the flat wiring material 10 as the mating direction, thereby electrically connecting the second connection object 300 and the flat wiring material 10. Moreover, the second connection object 300 is fastened by the fastening member 400 in a state connected to the flat wiring material 10, thereby being fixed to the installation object portion 100.

[0052] Specifically, if Figure 2 As shown, the fastening member 400 of the present embodiment is configured to include a bolt 410 and a nut 420. In addition, a flange 320 is provided as an auxiliary device of the second connection object 300, and the flange 320 is formed with a through hole for the bolt 410 to be inserted along the thickness direction Z of the flat wiring material 10. At this time, the bolt 410, for example, a head (not shown) is locked to the installation object part 100, and is installed in a state where the shaft part 411 extending from the head penetrates the installation object part 100 and the flange 320. In addition, the bolt 410 protrudes from the installation object part 100 side toward the second connection object 300 side, and is fastened to the nut 420 in a state of being inserted into the through hole formed in the flange 320 of the second connection object 300.

[0053] The flat wiring member 10 configured as described above further includes the mounting hole 12 and the slack forming portion 13 . The flat wiring member 10 is mounted to the mounting target portion 100 by inserting the mounting protrusion 110 provided in the mounting target portion 100 into the mounting hole 12 .

[0054] Here, the structure of the mounting protrusion 110 will be described.

[0055] The mounting protrusion 110 is a boss formed on the mounting target portion 100. Figure 1 As shown, the mounting protrusion 110 of the present embodiment is configured to include a shaft portion 111 and a locking claw portion 112 .

[0056] The shaft portion 111 is a small diameter portion formed on the base end side of the mounting protrusion 110. The shaft portion 111 of this embodiment is formed in a cylindrical shape. The shaft portion 111 is formed to extend from the surface 101 (see FIG. 101 ) of the mounting target portion 100 where the flat wiring material 10 is arranged. Figures 2 to 5 ) protrudes in a direction perpendicular to the surface 101 (the thickness direction Z of the flat wiring material 10).

[0057] The latching claw 112 is formed to protrude from the shaft 111 and is a large diameter portion formed at the end side of the mounting protrusion 110. The latching claw 112 of this embodiment is formed in a cylindrical shape. Figure 3 The outer diameter (112r) of the locking claw portion 112 shown in the figure is set larger than the size ( Figure 3 The outer diameter 111r of the shaft portion 111 is shown.

[0058] Furthermore, the structures of the mounting hole portion 12 through which the mounting protrusion 110 configured as described above is inserted and the slack forming portion 13 will be described.

[0059] The mounting hole portion 12 is a through hole formed along the thickness direction Z of the flat wiring material 10. Figure 1 As shown, the mounting hole portions 12 are formed in a substantially circular shape, and a pair of mounting hole portions 12 are provided at intervals. In addition, each mounting hole portion 12 is provided at intervals along the longitudinal direction X of the flat wiring material 10, and is formed at a position parallel to the second connector 30. In addition, one mounting hole portion 12 is provided between the first connector 20 and the second connector 30 provided at the end portion 10a of the flat wiring material 10, and the other mounting hole portion 12 is provided at a position on the opposite side of the one mounting hole portion 12 across the second connector 30. Therefore, as Figure 1 As shown, the second connector 30 is disposed between the pair of mounting hole portions 12 .

[0060] In addition, the size of the mounting hole 12 ( Figure 3 The inner diameter 12r of the mounting hole portion 12 shown in the figure is set to be larger than the size of the shaft portion 111 ( Figure 3 Therefore, in the state where the shaft portion 111 is inserted through the mounting hole portion 12 of the present embodiment, a gap is formed between the mounting hole portion 12 and the shaft portion 111 located inside.

[0061] In addition, the size of the mounting hole 12 is formed to be a size that allows the locking claw 112 to be inserted. Therefore, when the flat wiring material 10 of the present embodiment is mounted on the mounting target site 100 (laid on the mounting target site 100), the locking claw 112 is inserted into the mounting hole 12, and the mounting hole 12 is further pushed toward the mounting target site 100, so that the shaft 111 is inserted into the mounting hole 12. Moreover, when the mounting protrusion 110 is inserted into the mounting hole 12, the edge portion forming the mounting hole 12 is hooked on the locking claw 112 formed on the distal end side of the mounting protrusion 110, so that the flat wiring material 10 is locked to the mounting protrusion 110. In addition, the size of the locking claw 112 is not particularly limited as long as it can be inserted into the mounting hole 12 of the flat wiring material 10. For example, the size of the locking claw 112 may be set smaller than the size of the mounting hole 12, similarly to the shaft 111. The size of the locking claw portion 112 may be equal to or larger than the size of the mounting hole portion 12 , and may be set to a size that can be inserted into the mounting hole portion 12 by bending the flat wiring material 10 side.

[0062] In addition, the size of the mounting hole portion 12 is formed so that the flat wiring material 10 can move relatively along the plane direction of the flat wiring material within a range where the inner peripheral surface 12S of the mounting hole portion 12 abuts against the outer peripheral surface 111S of the shaft portion 111 formed on the base end side of the mounting protrusion 110. Therefore, when the flat wiring material 10 moves relatively along the plane direction, the second connector 30 provided on the surface 11 of the flat wiring material 10 can move relatively together with the flat wiring material.

[0063] The slack forming portion 13 is an excess length portion formed in one section of the flat wiring material 10 in a state where the flat wiring material 10 is installed in the installation target site 100. Figure 1As shown, the slack forming portion 13 of the present embodiment is formed between the first connector 20 provided at the end 10a of the flat wiring material 10 and the mounting hole portion 12 provided on the surface 11 of the flat wiring material 10. In addition, the slack forming portion 13 is formed by setting the length from the first connector 20 to the mounting hole portion 12 to be longer than the length from the fixed position of the first connector 20 in the first connection object 200 fixed to the mounting object portion 100 (the position of the first connection object side connector) to the mounting protrusion 110. Therefore, the slack forming portion 13 is set to a length that can form an excess length (slack) between the first connector 20 and the mounting hole portion 12 in a state where the first connector 20 is connected to the first connection object 200 and the mounting protrusion 110 is inserted through the mounting hole portion 12. Therefore, the flat wiring material 10 is mounted on the mounting object portion 100 in a state where the section from the first connector 20 to the mounting hole portion 12 is bent.

[0064] Next, refer to Figure 3 to Figure 7 , the assembly operation of the wiring harness 1 is described.

[0065] First, if Figure 3 As shown, the operator connects the first connector 20 provided at the end portion 10a of the flat wiring material 10 to the first connection object 200 previously fixed to the installation target portion 100. Then, in a state where the locking claw portion 112 of the installation protrusion portion 110 of the installation target portion 100 is inserted into the installation hole portion 12 formed in the flat wiring material 10, the operator pushes the flat wiring material 10 further toward the installation target portion 100, thereby inserting the shaft portion 111 of the installation protrusion portion 110 of the installation target portion 100 into the installation hole portion 12 of the flat wiring material 10.

[0066] Next, the operator adjusts the position of the second connector 30 provided on the surface 11 of the flat wiring material 10. In the flat wiring material 10 of the present embodiment, the inner diameter 12r of the mounting hole portion 12 is set larger than the outer diameter of the mounting protrusion 110. Therefore, the flat wiring material 10 can be moved along the plane direction ( Figure 3 The flat wiring material 10 is relatively moved in the XY direction shown in the figure, that is, in the direction along the plane direction of the installation target part 100. In addition, in the flat wiring material 10, since the slack forming part 13 is formed between the first connector 20 and the installation hole part 12, the slack forming part 13 can be expanded and contracted with the relative movement along the plane direction. Therefore, by allowing the slack forming part 13 to absorb the displacement caused by the relative movement, the flat wiring material 10 can prevent the relative movement from being hindered.

[0067] Specifically, if Figure 3 to Figure 5As shown, the flat wiring material 10 can move relative to the mounting target portion 100 along the length direction X. For example, the inner peripheral surface 12S of the mounting hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 are on the first connector 20 side ( Figure 3 When the flat wiring material 10 is in contact with the first connector 20, the flat wiring material 10 can be directed toward the side opposite to the first connector 20 ( Figure 3 And, as Figure 4 and Figure 5 As shown, the flat wiring material 10 is relatively movable until the inner peripheral surface 12S of the mounting hole portion 12 abuts against the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 on the side opposite to the first connector 20 side.

[0068] like Figures 3 to 5 As shown, the slack forming portion 13 of the flat wiring material 10 can adjust the slack amount 13z (the amount of deflection of the slack forming portion 13 relative to the mounting target portion 100) as the flat wiring material 10 moves. For example, when the inner peripheral surface 12S of the mounting hole portion 12 abuts against the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 on the first connector 20 side (see Figure 3 ), the slack amount 13z of the slack forming portion 13 is minimized, and the excess length of the flat wiring material 10 is absorbed. In addition, when the inner peripheral surface 12S of the mounting hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 are not in contact (refer to Figure 4 ), the center line x1 of the mounting hole portion 12 moves toward the direction close to the center line x2 of the shaft portion 111, so that the slack amount 13z of the slack forming portion 13 is smaller than Figure 3 In addition, when the inner peripheral surface 12S of the mounting hole portion 12 abuts against the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 on the side opposite to the first connector 20 side (see Figure 5 ), the center line x1 of the mounting hole portion 12 passes over the center line x2 of the shaft portion 111 and moves from the left side to the right side of the center line x2, so that the slack amount 13z of the slack forming portion 13 becomes maximum. Therefore, when the flat wiring material 10 is relatively moved along the longitudinal direction X with respect to the mounting target portion 100, the slack forming portion 13 can prevent the flat wiring material 10 from being strongly stretched in a non-slack state.

[0069] When the flat wiring member 10 moves in the longitudinal direction X, the second connector 30 provided in the flat wiring member 10 moves relatively together with the flat wiring member 10 in the longitudinal direction X. Therefore, the operator can adjust the position of the second connector 30 in the longitudinal direction X.

[0070] In addition, if Figure 6 , Figure 7 As shown, the flat wiring material 10 can move relative to the mounting target portion 100 along the width direction Y. For example, when the inner peripheral surface 12S of the mounting hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 are not in contact with each other, the flat wiring material 10 can move relatively until the inner peripheral surface 12S of the mounting hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 come into contact with each other.

[0071] In addition, when the flat wiring material 10 moves along the width direction Y, the second connector 30 provided in the flat wiring material 10 can relatively move along the width direction Y together with the flat wiring material 10. Figure 6 As shown, the second connector 30 of the present embodiment is arranged so that its center overlaps with the center of the flat wiring material 10 in the width direction Y. Therefore, when the inner peripheral surface 12S of the mounting hole portion 12 does not abut against the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 and the center line y1 of the mounting hole portion 12 is located at a position overlapping with the center line y2 of the shaft portion 111 (see Figure 6 ), the center of the second connector 30 is located at a position overlapping with the center of the shaft portion 111 in the width direction Y. In addition, on the contrary, when the inner peripheral surface 12S of the mounting hole portion 12 abuts against the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion 110 and the center line y1 of the mounting hole portion 12 is located at a position offset from the center line y2 of the shaft portion 111 (refer to Figure 7 ), the center of the second connector 30 is located at a position offset from the center of the shaft portion 111 in the width direction Y. Therefore, the operator can adjust the position of the second connector 30 in the width direction Y.

[0072] Therefore, according to the assembly operation of the wiring harness 1 described above, when the second connector 30 is mated with the second connection object 300, the second connector 30 can be relatively moved together with the flat wiring material 10, thereby adjusting the position of the second connector 30 relative to the installation object portion 100. Therefore, the second connector 30 can be appropriately aligned with respect to the second connection object 300.

[0073] The wiring harness 1 described above includes: a flat wiring material 10 having flexibility; a first connector 20 provided at an end 10a of the flat wiring material 10 and connected to a first connection target 200; and a second connector 30 provided on a surface 11 of the flat wiring material 10 and connected to a second connection target 300. The flat wiring material 10 has a mounting hole 12 formed at a position parallel to the second connector 30, and the mounting protrusion 110 provided at the mounting target portion 100 is inserted through the mounting hole 12, and the inner diameter 12r of the mounting hole 12 is set larger than the outer diameter of the mounting protrusion 110.

[0074] According to such a structure, by being configured to be able to adjust the position of the flat wiring material 10 relative to the installation object portion 100, the second connector 30 can be appropriately connected to the second connection object 300 whose position relative to the installation object portion 100 cannot be adjusted. Therefore, the wiring harness 1 can improve assemblability. In addition, the wiring harness 1 improves assemblability, thereby facilitating the connection operation (wiring operation) between the second connector 30 and the second connection object 300. Therefore, the wiring harness 1 can also improve operability.

[0075] Specifically, in the flat wiring material 10 of the wiring harness 1 described above, when the mounting protrusion 110 is inserted into the mounting hole 12, the edge of the mounting hole 12 can be locked with the locking claw 112 (large diameter portion) formed on the distal end side of the mounting protrusion 110, and the inner peripheral surface 12S of the mounting hole 12 and the outer peripheral surface 111S of the shaft 111 (small diameter portion) formed on the proximal end side of the mounting protrusion 110 can be abutted along the plane direction ( Figure 1 According to such a structure, the wire harness 1 can adjust the position of the flat wiring material 10 relative to the installation object part 100 in the plane direction (the two directions of the length direction X and the width direction Y). Therefore, the wire harness 1 can appropriately connect the second connector 30 to the second connection object 300. Therefore, the wire harness 1 can improve the assemblability.

[0076] Here, the second connector 30 of the wiring harness 1 described above can be mated with the second connection object 300 as the second connection object 300 is fixed to the installation object portion 100, and is connected in the plane direction ( Figure 1 The second connector 30 can be relatively moved in the XY direction (shown in the figure) to be aligned with the second connection object 300. According to such a structure, the wiring harness 1 can adjust the position of the second connector 30 relative to the installation object portion 100 in the same manner as the flat wiring material 10. Therefore, the wiring harness 1 can improve the assemblability by appropriately aligning the second connector 30 with respect to the second connection object 300.

[0077] In addition, the flat wiring material 10 of the wiring harness 1 described above has a slack forming portion 13, which forms an excess length between the first connector 20 and the mounting hole portion 12 in a state where the first connector 20 is connected to the first connection object 200 fixed to the installation object portion 100 and the mounting protrusion 110 is inserted into the mounting hole portion 12. According to such a structure, when the position of the flat wiring material 10 relative to the installation object portion 100 is adjusted, the slack forming portion 13 can be increased or decreased to allow the slack forming portion 13 to absorb the displacement caused by the relative movement. Therefore, the wiring harness 1 allows the displacement caused by the relative movement by applying the slack forming portion 13, and can prevent the movement from being hindered. Therefore, the wiring harness 1 can appropriately connect the second connector 30 to the second connection object 300, and can improve the assemblability.

[0078] Furthermore, the pair of mounting holes 12 formed in the flat wiring material 10 of the wiring harness 1 described above are arranged at intervals, and the second connector 30 is arranged between the pair of mounting holes 12. According to such a structure, the wiring harness 1 can adjust the position of the second connector 30 relative to the mounting target portion 100 on both sides of the second connector 30. Therefore, the wiring harness 1 can improve the assemblability by more appropriately aligning the second connector 30 with respect to the second connection target 300.

[0079] It should be noted that the wire harness 1 according to the above-described embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims.

[0080] For example, although it has been described that the flat wiring material 10 is an FPC, it may be an FFC (Flexible Flat Cable), and its structure is not particularly limited as long as it is composed of a flat wiring material having flexibility.

[0081] In addition, the case where a pair of mounting holes 12 are provided is described, but the number is not particularly limited. For example, only one mounting hole 12 may be provided, and its position may be located on either the first connector 20 side or the side opposite to the first connector 20 relative to the second connector 30.
