Modes for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by these embodiments. Also, the components in the following embodiments include those that can be replaced and are easy for 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 between each device mounted on the vehicle. The wire harness 1 of the present embodiment applies a flat wiring material 10 having flexibility as a wiring material, and the flat wiring material 10 is wired to an attachment target portion 100 that constitutes at least a part of the vehicle body panel. And the wire harness 1 realizes a configuration capable of improving the assemblability by forming the attachment hole portion 12 provided in the flat wiring material 10 larger than the attachment protrusion portion 110 provided in the attachment target portion 100. Hereinafter, with reference to FIGS. 1 to 7, the configuration of the wire harness 1 will be described in detail.

[0011] Note that the vehicle body panel mentioned here is a structural member (skeletal member) of the vehicle, and is, for example, a member such as a dash panel, a door panel, or a roof panel.

[0012] Also, in the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction 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 perpendicular to each other. Also, the length direction X typically corresponds to the longitudinal direction (extending direction) of the flat wiring material 10, and the width direction Y typically corresponds to the short-side direction of the flat wiring material 10. Also, the XY direction shown in FIGS. 1 to 7 corresponds to the plane direction of the flat wiring material 10. Note that each direction used in the following description is described as the direction in a state where the wire harness 1 is attached to the attachment target portion 100 unless otherwise specified.

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

[0014] The flat cable material 10 is a cable material that constitutes the wire harness 1. The flat cable material 10 of the present embodiment is a flexible printed circuit (FPC). The flat cable material 10 includes a base film, a wiring pattern, and a coverlay. Here, the base film is a base material that is excellent in flexibility and defines the overall shape of the flat cable material 10. The base film is formed of, for example, a polyimide resin having 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 of a metal material having conductivity, 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 for protecting the conductor circuit portions of the wiring pattern and the like.

[0015] As shown in FIG. 1, the flat cable material 10 is formed in a thin plate shape, extends along the length direction X and the width direction Y, and is formed in a substantially rectangular shape in which the thickness direction Z is the plate thickness direction. The flat cable material 10 of the present embodiment is formed along the length direction X and the width direction Y, and includes a main surface 11a configured as a surface having a larger area than other surfaces, and an end surface 11b formed along the thickness direction Z orthogonal to the main surface 11a and configured as a surface having a smaller area than the surface. And in the flat cable material 10 of the present embodiment, a second connector 30 is provided on the surface 11 of the main surface 11a of the flat cable material 10 (see FIG. 2).

[0016] The first connectors 20 are provided in a pair at intervals and are connection components respectively provided at both end portions 10a in the length direction X of the flat cable member 10. The first connectors 20 are electrically connected to the conductor circuit portion (pattern layer) of the flat cable member 10. Further, the first connectors 20 are respectively connected to the first connection targets 200 (see FIGS. 3 to 5) that are fixed in advance to the attachment target portion 100, so that the flat cable member 10 and the first connection targets 200 can be electrically connected.

[0017] The first connection targets 200 are, for example, control devices (ECUs: Electronic Control Units), and the devices are provided with first connection target side connectors that can be fitted with the first connectors 20. Therefore, the first connectors 20 are fitted with the first connection target side connectors with the direction intersecting the thickness direction Z of the flat cable member 10 (the length direction X of the flat cable member 10 in this embodiment) as the fitting direction, thereby electrically connecting the first connection targets 200 and the flat cable member 10. Further, the flat cable member 10 can electrically connect the control devices to each other when the pair of first connectors 20 are respectively fitted with the first connection target side connectors. Note that the first connection targets 200 may be devices other than ECUs, 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 connection component provided between the pair of first connectors 20. The second connector 30 is electrically connected to the conductor circuit portion (pattern layer) of the flat cable member 10. Further, the first connector 20 can be electrically connected to the second connection target 300 (see FIGS. 3 to 5) when the second connection target 300 is fixed to the attachment target portion 100, thereby electrically connecting the flat cable member 10 and the second connection target 300.

[0019] The second connection target 300 is, for example, an auxiliary device (auxiliary machine) used to operate the host machine, and in this embodiment, it is a control device (ECU). As shown in FIG. 2, the device is provided with a second connection target side connector 310 that can be fitted with the second connector 30. Therefore, the second connector 30 fits with the second connection target side connector 310 with the thickness direction Z of the flat cable material 10 as the fitting direction, thereby electrically connecting the second connection target 300 and the flat cable material 10. And the second connection target 300 is fixed to the attachment target portion 100 by being fastened by the fastening member 400 in a state of being connected to the flat cable material 10.

[0020] Specifically, as shown in FIG. 2, the fastening member 400 of this embodiment includes a bolt 410 and a nut 420. Further, the auxiliary machine which is the second connection target 300 is provided with a flange 320 in which a through hole through which the bolt 410 is inserted is formed along the thickness direction Z of the flat cable material 10. At this time, for example, the head (not shown) of the bolt 410 is locked to the attachment target portion 100, and the shaft portion 411 extending from the head is attached in a state of penetrating the attachment target portion 100 and the flange 320. And the bolt 410 protrudes from the attachment target portion 100 side toward the second connection target 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 target 300.

[0021] Further, the flat cable material 10 configured as described above further includes a mounting hole portion 12 and a slack forming portion 13. And the flat cable material 10 is attached to the attachment target portion 100 by the attachment protrusion portion 110 provided on the attachment target portion 100 being inserted into the attachment hole portion 12.

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

[0023] The attachment protrusion portion 110 is a boss formed on the attachment target portion 100. As shown in FIG. 1, the attachment protrusion portion 110 of this embodiment includes a shaft portion 111 and a locking claw portion 112.

[0024] The shaft portion 111 is a small-diameter portion formed on the proximal end side of the mounting protrusion portion 110. The shaft portion 111 of the present embodiment is formed in a cylindrical shape. Further, the shaft portion 111 protrudes in a direction orthogonal to the surface 101 (see FIGS. 2 to 5) where the flat cable member 10 is routed in the mounting target portion 100 (the thickness direction Z of the flat cable member 10).

[0025] The locking claw portion 112 is a large-diameter portion formed to protrude from the shaft portion 111 and formed on the distal end side of the mounting protrusion portion 110. The locking claw portion 112 of the present embodiment is formed in a cylindrical shape. Further, the size of the locking claw portion 112 (the 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 (the outer diameter 111r of the shaft portion 111 shown in FIG. 3).

[0026] Next, the mounting hole portion 12 through which the mounting protrusion portion 110 configured as described above is inserted and the structure of 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 cable member 10. As shown in FIG. 1, the mounting hole portion 12 is formed in a substantially circular shape, and a pair of them are provided at intervals. Further, the mounting hole portions 12 are provided at intervals along the length direction X of the flat cable member 10, and are respectively formed at positions aligned with the second connector 30. Further, one mounting hole portion 12 is provided between the first connector 20 provided at the end portion 10a of the flat cable member 10 and the second connector 30, and the other mounting hole portion 12 is provided at a position on the opposite side of one mounting hole portion 12 with the second connector 30 interposed therebetween. Therefore, as shown in FIG. 1, the second connector 30 is provided between the pair of mounting hole portions 12.

[0028] Further, the size of the mounting hole portion 12 (the inner diameter 12r of the mounting hole portion 12 shown in FIG. 3) is set to be larger than the size of the shaft portion 111 (the outer diameter 111r of the shaft portion 111 shown in FIG. 3). Therefore, in the present embodiment, a gap is formed between the inner shaft portion 111 and the mounting hole portion 12 with the shaft portion 111 inserted therethrough.

[0029] Further, the size of the mounting hole portion 12 is formed to be a size through which the locking claw portion 112 can be inserted. Therefore, when the flat cable member 10 of the present embodiment is attached to the attachment target portion 100 (cabled to the attachment 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 into the attachment target portion 100 side, so that the shaft portion 111 is inserted into the mounting hole portion 12. Then, when the mounting protrusion portion 110 is inserted into the mounting hole portion 12 of the flat cable member 10, the edge portion forming the mounting hole portion 12 is caught by the locking claw portion 112 formed on the tip end side of the mounting protrusion portion 110, and thus the flat cable member 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 a size that can be inserted into the mounting hole portion 12 of the flat cable member 10. For example, the size of the locking claw portion 112 may be set smaller than the size of the mounting protrusion portion 110, similar to the shaft portion 111. Further, the size of the locking claw portion 112 may be formed to be equal to or larger than the size of the mounting protrusion portion 110 and may be set to a size that can be inserted into the mounting hole portion 12 by bending the flat cable member 10 side.

[0030] Further, the size of the mounting hole portion 12 is formed to be a size that allows relative movement along the surface direction of the flat cable member within a 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 are in contact with each other. Therefore, when the flat cable member 10 moves relatively along the surface direction, the second connector 30 provided on the surface 11 of the flat cable member 10 can move relatively together with the flat cable member.

[0031] The slack forming portion 13 is an extra-length portion formed in a section of the flat wire rope 10 in a state where the flat wire rope 10 is attached to the attachment target portion 100. As shown in FIG. 1, the slack forming portion 13 of the present embodiment is formed between the first connector 20 provided at the end 10a of the flat wire rope 10 and the attachment hole portion 12 provided on the surface 11 of the flat wire rope 10. Further, the length of the slack forming portion 13 from the first connector 20 to the attachment hole portion 12 is set to be longer than the length from the fixed position of the first connector 20 (the position of the first connection target side connector) to the attachment protrusion portion 110 in the first connection target 200 fixed to the attachment target portion 100. Therefore, the slack forming portion 13 is set to a length that can form an extra length (slack) between the first connector 20 and the attachment hole portion 12 in a state where 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 wire rope 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, with reference to FIGS. 3 to 7, the assembly operation of the wire harness 1 will be described.

[0033] First, as shown in FIG. 3, the operator connects the first connector 20 provided at the end 10a of the flat wire rope 10 to the first connection target 200 that is pre-fixed 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 wire rope 10, the operator further pushes the flat wire rope 10 toward the attachment target portion 100 side to insert the shaft portion 111 of the attachment protrusion portion 110 of the attachment target portion 100 through the attachment hole portion 12 of the flat wire rope 10.

[0034] Next, the operator adjusts the position of the second connector 30 provided on the surface 11 of the flat wire rope 10. In the flat wire rope 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 projection portion 110. Therefore, the flat wire rope 10 can move relatively in 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 proximal end side of the mounting projection portion 110 are in contact with each other. Further, since the slack forming portion 13 is formed between the first connector 20 and the mounting hole portion 12 in the flat wire rope 10, the slack forming portion 13 can be expanded and contracted along with the relative movement along the surface direction. Therefore, the flat wire rope 10 can prevent the relative movement from being inhibited by absorbing the displacement due to the relative movement by the slack forming portion 13.

[0035] Specifically, as shown in FIGS. 3 to 5, the flat wire rope 10 can move relatively along the length direction X with respect to the mounting target portion 100. 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 projection portion 110 are in contact with each other on the first connector 20 side (the left side in FIG. 3), the flat wire rope 10 can move relatively toward the side opposite to the first connector 20 side (the right side in FIG. 3). Then, as shown in FIGS. 4 and 5, the flat wire rope 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 projection portion 110 are in contact with each other on the side opposite to the first connector 20 side.

[0036] In addition, as shown in FIGS. 3 to 5, the slack forming portion 13 of the flat wire rope 10 can adjust the slack amount 13z (the deflection amount of the slack forming portion 13 with respect to the attachment target portion 100) as the flat wire rope 10 moves. 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 in contact on the first connector 20 side (see FIG. 3), the slack amount 13z of the slack forming portion 13 is minimized, and the extra length of the flat wire rope 10 is absorbed. Also, 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 (see FIG. 4), by moving the center line x1 of the attachment hole portion 12 in a direction approaching the center line x2 of the shaft portion 111, the slack amount 13z of the slack forming portion 13 becomes larger than the form shown in FIG. 3. Further, 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 in contact on the side opposite to the first connector 20 side (see FIG. 5), by moving the center line x1 of the attachment hole portion 12 across the center line x2 of the shaft portion 111 from the left side to the right side of the center line x2, the slack amount 13z of the slack forming portion 13 becomes maximum. Therefore, when the flat wire rope 10 is relatively moved along the length direction X with respect to the attachment target portion 100, the slack forming portion 13 can prevent the flat wire rope 10 from being strongly tensioned without slack.

[0037] In addition, the second connector 30 provided on the flat wire rope 10 relatively moves along the length direction X together with the flat wire rope 10 when the flat wire rope 10 moves along the length direction X. Therefore, the operator can adjust the position of the second connector 30 in the length direction X.

[0038] In addition, as shown in FIGS. 6 and 7, the flat wire rope 10 can relatively move along the width direction Y with respect to the attachment target portion 100. 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, the flat wire rope 10 can relatively move 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 are in contact.

[0039] Further, the second connector 30 provided on the flat cable member 10 can move relative to the flat cable member 10 along the width direction Y when the flat cable member 10 moves along the width direction Y. For example, as shown in FIG. 6, the second connector 30 of the present embodiment is provided such that its center overlaps the center of the flat cable member 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 projection portion 110 are not in contact, and the center line y1 of the mounting hole portion 12 overlaps and is positioned with the center line y2 of the shaft portion 111 (see FIG. 6), the center of the second connector 30 is positioned overlapping the center of the shaft portion 111. Conversely, 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 projection portion 110 are in contact, and the center line y1 of the mounting hole portion 12 is displaced from the center line y2 of the shaft portion 111 (see FIG. 7), the center of the second connector 30 is displaced from the center of the shaft portion 111. Therefore, the operator 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 target 300 are fitted, the position of the second connector 30 with respect to the mounting target portion 100 can be adjusted by relatively moving the second connector 30 together with the flat cable member 10. Therefore, the second connector 30 can be appropriately aligned with the second connection target 300.

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

[0042] According to such a configuration, by configuring the flat cable member 10 to be able to adjust its position with respect to the mounting target portion 100, the second connector 30 can be properly connected to the second connection target 300 for which the position with respect to the mounting target portion 100 cannot be adjusted. Therefore, the wire harness 1 can improve its assemblability. Further, by improving the assemblability, the wire harness 1 makes the connection operation (wiring operation) between the second connector 30 and the second connection target 300 easier. Therefore, the wire harness 1 can also improve its workability.

[0043] Specifically, in the flat cable member 10 of the wire harness 1 described above, with the mounting protrusion 110 inserted through the mounting hole portion 12, the edge portion of the mounting hole portion 12 can be locked to the locking claw portion 112 (large diameter portion) formed on the tip side of the mounting protrusion 110, and within the 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 (small diameter portion) formed on the base end side of the mounting protrusion 110, it can move relatively along the surface direction (XY direction shown in FIG. 1) of the flat cable member 10. According to such a configuration, the wire harness 1 can adjust the position of the flat cable member 10 with respect to the mounting target portion 100 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 its assemblability.

[0044] Here, the second connector 30 of the wire harness 1 described above can be fitted with the second connection target 300 along with the fixing of the second connection target 300 to the mounting target portion 100, and can be aligned with the second connection target 300 by moving relatively in the surface direction (XY direction shown in FIG. 1) together with the flat cable member 10. According to such a configuration, the wire harness 1 can adjust the position of the second connector 30 with respect to the mounting target portion 100 in the same manner as the flat cable member 10. Therefore, the wire harness 1 can improve its assemblability by properly aligning the second connector 30 with the second connection target 300.

[0045] Furthermore, the flat cable member 10 of the wire harness 1 described above is connected to a first connection target 200 to which the first connector 20 is fixed to the mounting target portion 100, and has a slack forming portion 13 that forms a slack between the first connector 20 and the mounting hole portion 12 in a state where the mounting protrusion portion 110 is inserted into the mounting hole portion 12. According to such a configuration, when adjusting the position of the flat cable member 10 with respect to the mounting target portion 100, the wire harness 1 can absorb the displacement due to relative movement by increasing or decreasing the slack amount 13z of the slack forming portion 13. Therefore, the wire harness 1 can allow displacement due to relative movement by applying the slack forming portion 13 and prevent the movement from being inhibited. Therefore, the wire harness 1 can properly connect the second connector 30 to the second connection target 300 and improve the assemblability.

[0046] Furthermore, the mounting hole portions 12 formed in the flat cable member 10 of the wire harness 1 described above are provided in a pair at intervals, and the second connector 30 is provided between the pair of mounting hole portions 12. According to such a configuration, the wire harness 1 can adjust the position of the second connector 30 with respect to the mounting target portion 100 on both sides of the second connector 30. Therefore, the wire harness 1 can improve the assemblability by more appropriately aligning the second connector 30 with the second connection target 300.

[0047] Note 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 are possible within the scope described in the claims.

[0048] For example, although the flat cable member 10 has been described as being an FPC, it may be an FFC (Flexible Flat Cable), and its configuration is not particularly limited as long as it is composed of a flat cable member having flexibility.

[0049] Also, although the mounting hole portions 12 have been described as being provided in a pair, the number thereof is not particularly limited. For example, only one mounting hole portion 12 may be provided, and its position may be on the side of the first connector 20 with respect to the second connector 30 or on the side opposite to the first connector 20.

[0050] Also, the wire harness 1 according to the present embodiment may be configured by appropriately combining the components of the embodiments described above.
