[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] [Embodiment] The wire harness 1 shown in Fig. 1 is applied to a vehicle and is used for power supply and signal communication by connecting various devices mounted on the vehicle. The wire harness 1 of this embodiment uses a flexible flat wiring material 10 as a wiring material, and the flat wiring material 10 is routed to an attachment target portion 100 that constitutes at least a part of a vehicle body panel. The wire harness 1 has a configuration that can improve assembling by forming a mounting hole portion 12 provided in the flat wiring material 10 larger than a mounting protrusion portion 110 provided in the attachment target portion 100. The configuration of the wire harness 1 will be described in detail below with reference to Figs. 1 to 7.

[0011] The vehicle body panels referred to here are structural members (framework members) of a vehicle, such as dash panels, door panels, and roof panels.

[0012] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "length direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "thickness direction Z." Here, the length direction X, width direction Y, and thickness direction Z are perpendicular to one another. Furthermore, the length direction X typically corresponds to the longitudinal direction (extension direction) of the flat wiring material 10, and the width direction Y typically corresponds to the lateral direction of the flat wiring material 10. Furthermore, the XY directions shown in Figures 1 to 7 correspond to the surface direction of the flat wiring material 10. Note that, unless otherwise specified, each direction used in the following description will be described as the direction in a state in which the wire harness 1 is attached to the attachment target portion 100.

[0013] As shown in Figure 1, the wire harness 1 comprises a flexible flat wiring material 10, a first connector 20 provided at an end 10a of the flat wiring material 10, and a second connector 30 provided on a surface 11 of the flat wiring material 10.

[0014] The flat wiring material 10 is a wiring material that constitutes the wire harness 1. The flat wiring material 10 of this embodiment is a flexible printed circuit (FPC). The flat wiring material 10 is composed of a base film, a wiring pattern, and a coverlay. The base film here is a substrate that has excellent flexibility and determines the overall shape of the flat wiring material 10. The base film is formed, for example, from a polyimide resin that has excellent heat resistance. The wiring pattern is laminated, for example, on the surface of the base film and constitutes a plurality of conductor circuit portions (pattern layers). The wiring pattern is formed, for example, from a conductive metal material such as copper foil and printed as a printed circuit body on the surface of the base film. The coverlay is laminated on the entire surface of the base film via an adhesive (not shown) and functions as a protective layer that protects the conductor circuit portions of the wiring pattern.

[0015] 1, the flat wiring material 10 is formed in a thin plate shape, extending along the length direction X and the width direction Y, and is formed in a substantially rectangular shape with the thickness direction Z being the plate thickness direction. The flat wiring material 10 of this embodiment is formed to include a main surface 11a formed along the length direction X and the width direction Y and configured as a surface having a larger area than the other surfaces, and an end surface 11b formed along the thickness direction Z perpendicular to the main surface 11a and configured as a surface having a smaller area than the main surface 11a. The flat wiring material 10 of this embodiment has a second connector 30 provided on the surface 11 of the main surface 11a among the surfaces 11 of the flat wiring material 10 (see FIG. 2).

[0016] The first connectors 20 are connection parts provided in a pair at a distance from each other and provided at both end portions 10a in the longitudinal direction X of the flat wiring material 10. The first connectors 20 are electrically connected to the conductor circuit portion (pattern layer) of the flat wiring material 10. Furthermore, the first connectors 20 are respectively connected to first connection objects 200 (see Figures 3 to 5) that are fixed in advance to the attachment target portion 100, thereby electrically connecting the flat wiring material 10 and the first connection objects 200.

[0017] The first connection object 200 is, for example, a control device (ECU: Electronic Control Unit), and the device is provided with a first connection object side connector that can be fitted with the first connector 20. Therefore, the first connector 20 electrically connects the first connection object 200 and the flat wiring material 10 by fitting with the first connection object side connector in a fitting direction that intersects with the thickness direction Z of the flat wiring material 10 (in this embodiment, the length direction X of the flat wiring material 10). Furthermore, the flat wiring material 10 can electrically connect control devices to each other by fitting the pair of first connectors 20 with the first connection object side connectors. Note that the first connection object 200 may be a device other than an ECU, and various modifications are possible according to the specifications of the wire harness 1.

[0018] At least one second connector 30 is provided, and is a connecting component 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. Furthermore, when a second connection object 300 (see Figures 3 to 5) is fixed to the mounting target portion 100, the first connector 20 is connected to the second connection object 300, thereby electrically connecting the flat wiring material 10 and the second connection object 300.

[0019] The second connection object 300 is, for example, an auxiliary device (auxiliary machine) used to operate the main engine, and in this embodiment, it is a control device (ECU). The device is provided with a second connection object side connector 310 that can be fitted with the second connector 30, as shown in Fig. 2. Therefore, the second connector 30 electrically connects the second connection object 300 and the flat wiring material 10 by fitting with the second connection object side connector 310 with the thickness direction Z of the flat wiring material 10 as the fitting direction. Then, the second connection object 300 is fixed to the attachment target portion 100 by fastening with the fastening member 400 while connected to the flat wiring material 10.

[0020] Specifically, the fastening member 400 of this embodiment includes a bolt 410 and a nut 420, as shown in Fig. 2. The auxiliary machine, which is the second connection object 300, is provided with a flange 320 having a through hole formed therein, through which the bolt 410 is inserted, along the thickness direction Z of the flat routing material 10. At this time, the bolt 410 is attached, for example, with its head (not shown) engaged with the attachment target portion 100 and its shank 411 extending from the head penetrating the attachment target portion 100 and the flange 320. The bolt 410 protrudes from the attachment target portion 100 side toward the second connection object 300 side, and is fastened to the nut 420 while being inserted into a through hole formed in the flange 320 of the second connection object 300.

[0021] The flat wiring material 10 configured as described above further includes an attachment hole portion 12 and a slack forming portion 13. The flat wiring material 10 is attached to the attachment target portion 100 by inserting an attachment protrusion portion 110 provided on the attachment target portion 100 into the attachment hole portion 12.

[0022] Here, the structure of the mounting protrusion 110 will be described.

[0023] The mounting protrusion 110 is a boss formed on the mounting target portion 100. The mounting protrusion 110 of this embodiment includes a shaft portion 111 and a locking claw portion 112, as shown in FIG.

[0024] The shaft portion 111 is a small diameter portion formed on the base end side of the mounting protrusion portion 110. The shaft portion 111 in this embodiment is formed in a cylindrical shape. Moreover, the shaft portion 111 is formed to protrude from a surface 101 (see Figures 2 to 5) on which the flat wiring material 10 is routed in the mounting target portion 100 in a direction perpendicular to the surface 101 (thickness direction Z of the flat wiring material 10).

[0025] The locking claw portion 112 is formed to protrude from the shaft portion 111 and is a large-diameter portion formed on the tip side of the mounting protrusion 110. The locking claw portion 112 in this embodiment is formed in a cylindrical shape. The size of the locking claw portion 112 (outer diameter 112r of the locking claw portion 112 shown in FIG. 3) is set to be larger than the size of the shaft portion 111 (outer diameter 111r of the shaft portion 111 shown in FIG. 3).

[0026] Next, the structures of the mounting hole portion 12 into which the mounting protrusion portion 110 configured as described above is inserted and the slack forming portion 13 will be described.

[0027] The mounting hole portion 12 is a through hole formed along the thickness direction Z of the flat wiring material 10. As shown in FIG. 1, the mounting hole portion 12 is formed in a substantially circular shape and is provided in a pair with a gap between them. Furthermore, each mounting hole portion 12 is provided with a gap between them along the length direction X of the flat wiring material 10, and is formed at a position aligned with the second connector 30. Furthermore, 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 opposite to the one mounting hole portion 12 with the second connector 30 sandwiched between them. Therefore, the second connector 30 is provided between the pair of mounting holes 12 as shown in FIG. 1.

[0028] Furthermore, the size of the mounting hole 12 (inner diameter 12r of the mounting hole 12 shown in FIG. 3) is set larger than the size of the shaft 111 (outer diameter 111r of the shaft 111 shown in FIG. 3). Therefore, when the shaft 111 is inserted through the mounting hole 12 of this embodiment, a gap is formed between the mounting hole 12 and the shaft 111 located on the inside.

[0029] Further, the size of the mounting hole portion 12 is formed to a size that allows the locking claw portion 112 to be inserted therethrough. Therefore, when the flat wiring material 10 of this embodiment is attached to the mounting target portion 100 (wired into the mounting target portion 100), the locking claw portion 112 is inserted into the mounting hole portion 12, and the mounting hole portion 12 is further pushed toward the mounting target portion 100, thereby inserting the shaft portion 111 into the mounting hole portion 12. Then, when the mounting protrusion portion 110 is inserted into the mounting hole portion 12, the edge portion forming the mounting hole portion 12 is caught on the locking claw portion 112 formed on the tip side of the mounting protrusion portion 110, so that the flat wiring material 10 is locked to the mounting protrusion portion 110. Note that the size of the locking claw portion 112 is not particularly limited as long as it is large enough to be inserted into the mounting hole portion 12 of the flat wiring material 10. For example, the size of the locking claw portion 112, like the shaft portion 111, may be Mounting hole 12 The size of the locking claw portion 112 may be set smaller than the size of the locking claw portion 112. Mounting hole 12 The flat wiring material 10 may be formed to have a size equal to or larger than the size of the flat wiring material 10, and may be set to a size that allows it to be inserted into the mounting hole portion 12 by bending the flat wiring material 10 side.

[0030] The size of the mounting hole 12 is formed to allow relative movement along the surface direction of the flat wiring material within the range where the inner peripheral surface 12S of the mounting hole 12 and the outer peripheral surface 111S of the shaft 111 formed on the base end side of the mounting protrusion 110 abut against each other. Therefore, when the flat wiring material 10 moves relatively along the surface 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.

[0031] The slack forming portion 13 is an excess length portion formed in one section of the flat wiring material 10 when the flat wiring material 10 is attached to the attachment target portion 100. As shown in FIG. 1 , the slack forming portion 13 in this embodiment is formed between the first connector 20 provided at the end 10a of the flat wiring material 10 and the attachment hole portion 12 provided on the surface 11 of the flat wiring material 10. The slack forming portion 13 is formed by setting the length from the first connector 20 to the attachment hole portion 12 to be longer than the length from the fixed position of the first connector 20 (the position of the first connection target side connector) in the first connection target 200 fixed to the attachment target portion 100 to the attachment protrusion portion 110. Therefore, the slack forming portion 13 is set to a length that allows excess length (slack) to be formed between the first connector 20 and the attachment hole portion 12 when the first connector 20 is connected to the first connection target 200 and the attachment protrusion portion 110 is inserted into the attachment hole portion 12. Therefore, the flat wiring material 10 is attached to the attachment target portion 100 in a state where the section from the first connector 20 to the attachment hole portion 12 is bent.

[0032] Next, an assembly operation of the wire harness 1 will be described with reference to FIGS.

[0033] First, as shown in Fig. 3, the worker connects the first connector 20 provided at the end 10a of the flat wiring material 10 to the first connection object 200 that has been fixed in advance to the attachment target portion 100. Then, with the locking claw portion 112 of the attachment protrusion portion 110 of the attachment target portion 100 inserted into the attachment hole portion 12 formed in the flat wiring material 10, the worker further pushes the flat wiring material 10 toward the attachment target portion 100, thereby inserting the shaft portion 111 of the attachment protrusion portion 110 of the attachment target portion 100 into the attachment hole portion 12 of the flat wiring material 10.

[0034] Next, the worker 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 this embodiment, the inner diameter 12r of the mounting hole portion 12 is set larger than the outer diameter of the mounting protrusion portion 110. Therefore, the flat wiring material 10 can move relatively along the surface direction (the XY direction shown in FIG. 3, which is the direction along the surface direction of the mounting target portion 100) within the range where the inner peripheral surface 12S of the mounting hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 formed on the base end side of the mounting protrusion portion 110 abut. Furthermore, since the flat wiring material 10 has a slack-forming portion 13 formed between the first connector 20 and the mounting hole portion 12, the slack-forming portion 13 can expand and contract in accordance with the relative movement along the surface direction. Therefore, the flat wiring material 10 can prevent the relative movement from being hindered by allowing the slack-forming portion 13 to absorb the displacement due to the relative movement.

[0035] Specifically, as shown in Figures 3 to 5, the flat wiring material 10 can move relative to the attachment target portion 100 along the length direction X. For example, when the inner peripheral surface 12S of the attachment hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the attachment protrusion portion 110 abut on the first connector 20 side (the left side in Figure 3), the flat wiring material 10 can move relatively toward the opposite side from the first connector 20 side (the right side in Figure 3). Then, as shown in Figures 4 and 5, the flat wiring material 10 can move relatively until the inner peripheral surface 12S of the attachment hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the attachment protrusion portion 110 abut on the opposite side from the first connector 20 side.

[0036] 3 to 5, the slack forming portion 13 of the flat wiring material 10 can adjust the amount of slack 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 and the outer peripheral surface 111S of the shaft portion 111 of the mounting protrusion portion 110 abut on the first connector 20 side (see FIG. 3), the amount of slack 13z of the slack forming portion 13 is minimized, and the excess length of the flat wiring material 10 is absorbed. 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 portion 110 do not abut (see FIG. 4), the center line x1 of the mounting hole portion 12 moves in a direction approaching the center line x2 of the shaft portion 111, and the amount of slack 13z of the slack forming portion 13 becomes larger than that in the form shown in FIG. 3. Furthermore, 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 portion 110 abut on the side opposite to the first connector 20 side (see FIG. 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, thereby maximizing the amount of slack 13z of the slack forming portion 13. Therefore, when the flat wiring material 10 is moved relative to the mounting target portion 100 in the length direction X, the slack forming portion 13 can prevent the flat wiring material 10 from being tightly tensioned in a state where there is no slack.

[0037] Furthermore, when the flat wiring material 10 moves along the length direction X, the second connector 30 provided on the flat wiring material 10 moves relatively along the length direction X together with the flat wiring material 10. Therefore, the worker can adjust the position of the second connector 30 in the length direction X.

[0038] 6 and 7, the flat wiring material 10 can move relative to the attachment target portion 100 along the width direction Y. For example, when the inner peripheral surface 12S of the attachment hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the attachment protrusion portion 110 are not in contact with each other, the flat wiring material 10 can move relative to the attachment target portion 100 until the inner peripheral surface 12S of the attachment hole portion 12 and the outer peripheral surface 111S of the shaft portion 111 of the attachment protrusion portion 110 come into contact with each other.

[0039] Furthermore, when the flat wiring material 10 moves along the width direction Y, the second connector 30 provided on the flat wiring material 10 can move relatively along the width direction Y together with the flat wiring material 10. For example, as shown in FIG. 6, the second connector 30 of this embodiment is provided so that its center overlaps with the center of the flat wiring material 10. Therefore, 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 portion 110 are not in contact with each other and the center line y1 of the mounting hole portion 12 overlaps with the center line y2 of the shaft portion 111 (see FIG. 6), the center of the second connector 30 overlaps with the center of the shaft portion 111. Conversely, when the inner peripheral surface 12S of the mounting hole 12 and the outer peripheral surface 111S of the shaft 111 of the mounting protrusion 110 are in contact with each other and the center line y1 of the mounting hole 12 is misaligned with the center line y2 of the shaft 111 (see FIG. 7), the center of the second connector 30 is misaligned with the center of the shaft 111. Therefore, the worker can adjust the position of the second connector 30 in the width direction Y.

[0040] Therefore, according to the assembling operation of the wire harness 1 described above, when the second connector 30 and the second connection object 300 are fitted together, the second connector 30 can be moved relatively together with the flat wiring material 10, thereby adjusting the position of the second connector 30 with respect to the attachment object portion 100. Therefore, the second connector 30 can be appropriately aligned with the second connection object 300.

[0041] The wire harness 1 described above comprises a flexible flat wiring material 10, a first connector 20 provided at an end 10a of the flat wiring material 10 and connected to a first connection object 200, and a second connector 30 provided on a surface 11 of the flat wiring material 10 and connected to a second connection object 300. The flat wiring material 10 also has a mounting hole 12 formed in a position aligned with the second connector 30 and through which a mounting protrusion 110 provided on the mounting target portion 100 is inserted, and an inner diameter 12r of the mounting hole 12 is set larger than an outer diameter of the mounting protrusion 110.

[0042] According to this configuration, by configuring the position of the flat wiring material 10 relative to the attachment target portion 100 to be adjustable, the second connector 30 can be properly connected to the second connection target 300 whose position relative to the attachment target portion 100 cannot be adjusted. Therefore, the wire harness 1 can improve the assemblability. Furthermore, by improving the assemblability of the wire harness 1, the connection work (wiring work) between the second connector 30 and the second connection target 300 becomes easier. Therefore, the wire harness 1 can also improve the workability.

[0043] Specifically, in the flat wiring material 10 of the wire 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 engaged with the locking claw 112 (large diameter portion) formed on the tip side of the mounting protrusion 110, and the flat wiring material 10 can be relatively moved along the surface direction (XY direction shown in FIG. 1 ) of the flat wiring material 10 within a range where 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 base end side of the mounting protrusion 110 abut against each other. With this configuration, the position of the flat wiring material 10 relative to the mounting target portion 100 can be adjusted in the surface direction (in two directions, the length direction X and the width direction Y). Therefore, the wire harness 1 can properly connect the second connector 30 to the second connection target 300. Therefore, the wire harness 1 can improve the assemblability.

[0044] Here, the second connector 30 of the wire harness 1 described above can be fitted to the second connection object 300 as the second connection object 300 is fixed to the attachment target portion 100, and can be aligned with the second connection object 300 by moving relatively together with the flat wiring material 10 in the planar direction (the XY direction shown in FIG. 1 ). With this configuration, the position of the second connector 30 of the wire harness 1 relative to the attachment target portion 100 can be adjusted in the same way as the flat wiring material 10. Therefore, the wire harness 1 can improve the ease of assembly by appropriately aligning the second connector 30 with the second connection object 300.

[0045] Furthermore, the flat wiring material 10 of the wire harness 1 described above has a slack forming portion 13 that forms an excess length between the first connector 20 and the mounting hole 12 when the first connector 20 is connected to the first connection object 200 fixed to the mounting target portion 100 and the mounting protrusion 110 is inserted into the mounting hole 12. With this configuration, when adjusting the position of the flat wiring material 10 relative to the mounting target portion 100, the slack forming portion 13 can absorb displacement due to relative movement by increasing or decreasing the slack amount 13z of the slack forming portion 13. Therefore, by applying the slack forming portion 13, the wire harness 1 can tolerate displacement due to relative movement and prevent the movement from being obstructed. Therefore, the wire harness 1 can properly connect the second connector 30 to the second connection object 300, improving assemblability.

[0046] Furthermore, the mounting hole portions 12 formed in the flat wiring material 10 of the wire harness 1 described above are provided as a pair spaced apart, and the second connector 30 is provided between the pair of mounting hole portions 12. With this configuration, the position of the second connector 30 relative to the attachment target portion 100 of the wire harness 1 can be adjusted on both sides of the second connector 30. Therefore, the wire harness 1 can improve the ease of assembly by more appropriately aligning the second connector 30 with the second connection target 300.

[0047] The wire harness 1 according to the embodiment of the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims.

[0048] For example, although the flat wiring material 10 has been described as an FPC, it may also be an FFC (Flexible Flat Cable), and its configuration is not particularly limited as long as it is made of a flexible flat wiring material.

[0049] Although the mounting holes 12 are described as being provided in pairs, the number of mounting holes is not particularly limited. For example, only one mounting hole 12 may be provided, and the position of the mounting hole 12 may be either on the first connector 20 side or on the opposite side of the first connector 20 from the second connector 30.

[0050] The wire harness 1 according to the present embodiment may be configured by appropriately combining the components of the above-described embodiments. [Explanation of symbols]
