Embodiments 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 the following embodiments. In addition, the components in the following embodiments include those that can be replaced by those skilled in the art and are easy to replace, or those that are substantially the same. In this specification, ordinal numbers are used only for distinguishing parts, members, parts, positions, directions, etc., and do not indicate order or priority.

[0010] [Embodiment] FIG. 1 is a perspective view of a vehicle 100 to which a wire harness WH according to an embodiment is applied. The wire harness WH of the present embodiment shown in FIG. 1 is applied to the vehicle 100 and is used to connect between the respective devices mounted on the vehicle 100 and for power supply and signal communication. The wire harness WH of the present embodiment is provided, for example, on the dash panel 120 of the vehicle 100 and is installed inside the instrument panel (not shown) of the vehicle 100. The dash panel 120 is a partition wall that separates the engine room 130 of the vehicle 100 from the passenger compartment (cabin) and constitutes a structural member (skeletal member) of the vehicle 100.

[0011] Here, in the present embodiment, the dash panel 120 includes, for example, a dash panel main body 125 made of metal and a vehicle body panel 110 made of resin. And, in the present embodiment, the dash panel main body 125 is integrally molded with the peripheral panel 115 and the like of the engine room 130. Thereby, the rigidity and strength of the dash panel 120 can be increased, and as a result, the vehicle body panel 110 can be constituted by a resin molded product. That is, in the present embodiment, the vehicle body panel 110 is constituted by a separate part from the dash panel main body 125. The vehicle body panel 110 is installed, for example, in a recess 121 formed in the dash panel main body 125 and constitutes a part of the dash panel 120 together with the dash panel main body 125.

[0012] 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 "lamination direction X", the second direction is referred to as the "extending direction Y", and the third direction is referred to as the "width direction Z". Here, the lamination direction X, the extending direction Y, and the width direction Z are substantially orthogonal to each other. The lamination direction X typically corresponds to the lamination direction between the first lamination module 10 and the second lamination module 20 of the wire harness WH and extends along the vehicle front-rear direction. The extending direction Y typically corresponds to the longitudinal direction (extending direction) of the flat cable member 11 of the wire harness WH and extends along the vehicle width direction. The width direction Z typically corresponds to the short-side direction of the flat cable member 11 of the wire harness WH and extends along the vehicle height direction. Note that each direction used in the following description will be described as the direction in a state where the wire harness WH is assembled to the vehicle 100 unless otherwise specified.

[0013] FIG. 2 is a perspective view of the wire harness WH, and FIG. 3 is an exploded perspective view of the wire harness WH. As shown in FIGS. 2 and 3, the wire harness WH of the present embodiment includes, for example, a first lamination module 10 and a second lamination module 20. The first lamination module 10 includes a flat cable member 11 extending along the extending direction Y and a plurality of first connectors 12 provided on the surface 11a of the flat cable member 11. Here, the first lamination module 10 is connected to the first ECU 40A (see FIG. 1) of the control device 40 via the first connector 12 provided at one end portion 10b in the extending direction Y, and is connected to the second ECU 40E of the control device 40 via another first connector 12 provided at the other end portion 10b in the extending direction Y.

[0014] Note that the first ECU 40A and the second ECU 40E here are typically zone ECUs that comprehensively control the devices in the peripheral area (zone) of the dash panel 120, but are not limited to this. Also, between the first ECU 40A and the second ECU 40E, a plurality of devices 40B to 40D such as other ECUs of the control device 40 are provided. The device 40B is electrically connected to the flat cable material 11 via the first connector 12 provided at the central portion of the first laminated module 10 in the extending direction Y, and the device 40D is electrically connected to the flat cable material 11 via another first connector 12 provided at the central portion of the first laminated module 10 in the extending direction Y.

[0015] As shown in FIGS. 2 and 3, the flat cable material 11 is a cable material that constitutes the wire harness WH and is composed of, for example, FPC (Flexible Printed Circuits), FFC (Flexible Flat Cable), or the like. The flat cable material 11 is a thin and flexible flat cable material. The flat cable material 11 is formed in an overall rectangular plate shape that is horizontally long in the extending direction Y. The flat cable material 11 includes, for example, a base film, a wiring pattern, and a coverlay.

[0016] The base film is a base material that is excellent in flexibility and defines the overall shape of the flat cable material 11. The base film is formed of, for example, a polyimide resin or the like that is excellent in heat resistance. The wiring pattern is laminated on the surface (mounting surface) of the base film and constitutes a plurality of conductor circuit portions (pattern layers). The wiring pattern is formed of a conductive material such as copper foil, for example, and is 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 and the like.

[0017] Further, the flat cable member 11 has, for example, four first connectors 12. Here, one first connector 12 is provided at each of the end portions 11b on both sides in the extending direction Y of the flat cable member 11, and two first connectors 12 are provided at the end portion on one side in the width direction Z. These first connectors 12 are connected to the control device 40 via the connector 41 (see FIG. 4) on the control device 40 side described above.

[0018] Also, the plurality of first connectors 12 are electrically connected to the wiring pattern of the flat cable member 11. The plurality of conductor circuit portions formed by the wiring pattern can function as, for example, any one of a signal circuit, a signal GND circuit, a power ground circuit, etc. The signal circuit is, for example, a circuit that transmits communication signals between the control device 40 and in-vehicle devices such as various electronic devices in the vehicle 100. The signal GND circuit is electrically connected between the in-vehicle devices following the signal circuit and adjusts the potential serving as a reference for the circuit operation between the in-vehicle devices. The power ground circuit is a circuit that grounds the power supply system of the in-vehicle device.

[0019] The second laminated module 20 is a wiring module laminated on the first laminated module 10. The second laminated module 20 includes a plurality of cable members 21 having conductivity and a plurality of second connectors 22 provided at the terminals of the plurality of cable members 21. Here, the second laminated module 20 has, for example, four second connectors 22 and is laminated on the surface 11a of the flat cable member 11. Then, the second laminated module 20 is connected to the first ECU 40A (see FIG. 1) of the control device 40 via the second connector 22 provided at one end portion 10b in the extending direction Y, and is connected to the second ECU 40E of the control device 40 via another second connector 22 provided at the other end portion 10b in the extending direction Y.

[0020] Among the plurality of devices 40B to 40D arranged between the first ECU 40A and the second ECU 40E, for example, the device 40C is electrically connected to a plurality of wiring materials 21 via a second connector 22 provided at the center of the second laminated module 20 in the extending direction Y, and the device 40D is electrically connected to the plurality of wiring materials 21 via another second connector 22 provided at the center of the second laminated module 20 in the extending direction Y.

[0021] The plurality of wiring materials 21 are, for example, special electric wires that transmit signals or power that are difficult to transmit appropriately with the flat wiring material 11, and are composed of high-speed communication lines that transmit high-speed communication signals, power lines (thick wires) that transmit large-current power, and the like. In other words, the plurality of wiring materials 21 are composed of wiring materials 21 that cannot ensure performance (shielding performance) like a high-speed communication line or wiring materials 21 that become large-sized like a thick wire when trying to be placed inside the flat wiring material 11. Each of the plurality of wiring materials 21 includes a linear conductor portion (see FIG. 6) and an insulating coating that covers the outside of the conductor portion. When the plurality of wiring materials 21 are, for example, high-speed communication lines, they are composed of shielded wires in which the outside of the insulating coating is further covered with a shield such as a braided body.

[0022] FIG. 4 is a perspective view showing the connection structure between the first connector 12 and the second connector 22 of the wire harness WH and the connectors 41 and 42 on the control device 40 side, and FIG. 5 is a schematic exploded perspective view of the vicinity of the second connector 22 of the wire harness WH. As shown in FIGS. 4 and 5, in the present embodiment, the plurality of wiring materials 21 are arranged side by side in a planar manner along the surface 11a of the flat wiring material 11. The second laminated module 20 is configured in a flat shape that has a certain lateral width in the width direction Z and is thinned in the lamination direction X by the plurality of wiring materials 21 arranged side by side in the width direction Z.

[0023] Here, in the present embodiment, the second laminated module 20 is laminated along the lamination direction X with the second connector 22 and the first connector 12 facing one side of the lamination direction X with respect to the first laminated module 10. Specifically, in the present embodiment, the first connector 12 and the second connector 22 face the vehicle interior side (control device 40 side) opposite to the vehicle body panel 110 described above in the lamination direction X. The first connector 12 can be connected to the connector 41 on the control device 40 side such as the first ECU 40A, and the second connector 22 can be connected to the connector 42 on the control device 40 side such as the first ECU 40A. In this way, the first connector 12 and the second connector 22 are arranged in a standby state with respect to the control device 40 such as the first ECU 40A.

[0024] Also, in the present embodiment, the first laminated module 10 is provided with openings 11g (see FIG. 5) through which the flat cable material 11 penetrates along the lamination direction X. The openings 11g are provided in a pair, for example, at both ends in the width direction Z of the flat cable material 11. And the second connector 22 has a pair of leg portions 22a that protrude toward the other side in the lamination direction X and are inserted into the respective openings 11g of the flat cable material 11. The second connector 22 is positioned with respect to the flat cable material 11 by the engagement between the pair of leg portions 22a and the pair of openings 11g. Further, the second connector 22 is installed in a state where the leg portions 22a are in contact with the vehicle body panel 110 (see FIG. 6) through the openings 11g.

[0025] FIG. 6 is a cross-sectional view showing the connection structure between the first connector 12 and the second connector 22 of the wire harness WH and the connectors 41 and 42 on the control device 40 side. As shown in FIG. 6, in the present embodiment, the first laminated module 10 is arranged on the vehicle body panel 110 side with respect to the second laminated module 20, and the second laminated module 20 is laminated on the surface 11a of the flat cable material 11 opposite to the vehicle body panel 110 in the lamination direction X. That is, the second laminated module 20 is arranged on the vehicle interior side (control device 40 side) with respect to the first laminated module 10, and the first connector 12 and the second connector 22 face the vehicle interior side (control device 40 side) opposite to the vehicle body panel 110.

[0026] Here, in the present embodiment, the first connector 12 and the second connector 22 are mutually fitted with the above-described connectors 41 and 42 on the control device 40 side in response to the fastening of the control device 40 to the vehicle body panel 110 by the fastening member 50. Specifically, in the present embodiment, the fastening member 50 includes a bolt 51 and a nut 52, and the control device 40 is provided with a flange in which a through hole through which the bolt 51 is inserted along the stacking direction X is formed. The bolt 51 is, for example, attached in a state where the head portion 51a is locked to the outer surface of the vehicle body panel 110 (the surface opposite to the first stacked module 10) and the shaft portion 51b penetrates the vehicle body panel 110.

[0027] Then, the bolt 51 protrudes from the vehicle body panel 110 toward one side (the control device 40 side) in the stacking direction X, and is fastened to the nut 52 in a state of being inserted into the through hole formed in the flange of the control device 40. Thereby, the bolt 51 functions as an assist bolt when the first connector 12 and the second connector 22 are collectively fitted with the connectors 41 and 42 on the control device 40 side, and thus the fitting operation of the first connector 12 and the second connector 22 with the connectors 41 and 42 on the control device 40 side can be performed more easily or more smoothly. The fastening member 50 and the flange are provided in a pair on both sides in the width direction Z so as to sandwich the first connector 12 and the second connector 22 therebetween, for example.

[0028] FIG. 7 is an exploded perspective view of the second connector 22 on the other side in the extending direction Y of the wire harness WH, and FIG. 8 is a perspective view of the second connector 22 of FIG. 7. As shown in FIGS. 7 and 8, the second connector 22 includes, for example, a housing 22A, an under cover 22B, and a plurality of connector terminals 23 and 24. The housing 22A covers the plurality of wiring members 21 and the plurality of connector terminals 23 and 24 from one side in the stacking direction X, and the under cover 22B covers the plurality of wiring members 21 and the plurality of connector terminals 23 and 24 from the other side in the stacking direction X. The housing 22A and the under cover 22B are formed of, for example, an insulating synthetic resin or the like.

[0029] The plurality of connector terminals 23 and 24 are electrically connected to the terminals of the connector 42 on the control device 40 side. The connector terminals 23 and 24 are configured to include, for example, an electrical connection portion that is electrically connected to the terminals of the connector 42 on the control device 40 side, and a wire connection portion that is electrically connected to the conductor portion at the end of the wiring material 21. The connector terminal 23 is, for example, a connector terminal conforming to the LVDS (Low Voltage Differential Signaling) standard, and the connector terminal 24 is a connector terminal of a standard different from that of the connector terminal 23.

[0030] The housing 22A is configured to include, for example, an upper wall portion 22b, a pair of side wall portions 22c, and a pair of end wall portions 22d. The upper wall portion 22b, the pair of side wall portions 22c, and the pair of end wall portions 22d are structures for partitioning the insertion space portions 22e and 22f of the housing 22A. The insertion space portions 22e and 22f are space portions through which the above-described connector terminals 23 and 24 are inserted along the stacking direction X. The insertion space portions 22e and 22f penetrate the upper wall portion 22b along the stacking direction X and are arranged side by side along the width direction Z. The plurality of connector terminals 23 and 24 are held in a state of being partitioned from each other in the width direction Z by the housing 22A.

[0031] The under cover 22B is configured to include, for example, a lower wall portion 22g and a pair of end wall portions 22h. The under cover 22B covers the plurality of wiring materials 21 and the connector terminals 23 and 24 from the other side in the stacking direction X and both sides in the width direction Z by the lower wall portion 22g and the pair of end wall portions 22h, and both sides in the extending direction Y are open. Further, the lower wall portion 22g is provided with recesses 22i for holding the plurality of wiring materials 21 and the connector terminals 23 and 24. The recesses 22i are recessed in a two-stage manner along the outer shape of the plurality of wiring materials 21 and the connector terminals 23 and 24. Further, the pair of end wall portions 22h are provided with locking holes 22j into which claw portions provided on the inner surfaces of the pair of end wall portions 22d of the housing 22A are locked. The under cover 22B is integrated with the housing 22A by a so-called snap fit by the locking of the locking holes 22j and the claw portions.

[0032] FIG. 9 is an exploded perspective view of a second connector 22 on one side in the extending direction Y of the wire harness WH. As shown in FIG. 9, in this embodiment, the under cover 22B is open on both sides in the extending direction Y. For this reason, the plurality of wiring members 21 can be drawn out from either direction on both sides in the extending direction Y with respect to the under cover 22B. As a result, the under cover 22B can be shared by the second connector 22 on the other side in the extending direction Y of the wire harness WH described above, in which the drawing directions of the plurality of wiring members 21 are different, and the second connector 22 on one side in the extending direction Y. In FIG. 9, for convenience, the housing 22A of the second connector 22 is not shown.

[0033] Thus, the second laminated module 20 of this embodiment is configured to include a plurality of wiring members 21 and a second connector 22. With this configuration, for example, when trying to put it inside the flat wiring member 11, wiring members 21 etc. whose performance (shielding performance) cannot be ensured like a high-speed communication line can be bundled by the second connector 22. As a result, compared with the conventional structure in which a plurality of high-speed communication lines are individually connected to the control device 40, the connection work for the control device 40 can be performed more easily, more smoothly, or more quickly.

[0034] Further, the wire harness WH of this embodiment is configured to include the flat wiring member 11. Therefore, the wire harness WH composed of the flat wiring member 11 is lighter in weight compared with a wire harness in which various general electric wires are bundled. Here, when the above wire harness WH is installed in the vehicle 100, it is also assumed that the length of the wire harness WH is about 1000 mm. If the wire harness WH of such a length is entirely composed of electric wires, there is a risk that the overall weight of the wire harness WH will increase. In that regard, according to this embodiment, since the wire harness WH is configured to include the flat wiring member 11, it is possible to cope with the increase in size of the wire harness WH while suppressing an increase in the overall weight of the wire harness WH.

[0035] In general, a wire harness in which various electric wires are bundled is manufactured manually by an operator. On the other hand, since the flat wiring material 11 can be manufactured by automation, by configuring the wire harness WH with the flat wiring material 11, the manufacturing man-hours of the wire harness WH can be reduced. Also, in general, a large wire harness in which various electric wires are bundled has difficulty in transportation due to its weight. On the other hand, according to the present embodiment, there are also advantages such as shortening the manufacturing days of, for example, the wire harness WH itself or the vehicle 100 using the wire harness WH, or making it less likely that the manufacturing location is limited, by the flat wiring material 11.

[0036] As described above, the wire harness WH of the present embodiment includes a first laminated module 10 having a flexible flat wiring material 11 and a first connector 12 provided on the flat wiring material 11, and a plurality of conductive wiring materials 21 and a second laminated module 20 having a second connector 22 provided on the plurality of wiring materials 21. The second laminated module 20 is laminated along the lamination direction X with respect to the first laminated module 10 in a state where the second connector 22 and the first connector 12 face one side in the lamination direction X that intersects the extending direction Y of the flat wiring material 11. With this configuration, the wire harness WH can, for example, laminate and arrange the second laminated module 20 with respect to the first laminated module 10 in a state where the second connector 22 and the first connector 12 face one side in the lamination direction X along the lamination direction X. As a result, the wire harness WH can improve the assemblability to the vehicle 100.

[0037] Also, in the wire harness WH of the present embodiment, the plurality of wiring materials 21 are constituted by communication lines that transmit signals or power lines that transmit power, and are arranged side by side in a planar manner. With this configuration, the wire harness WH can, for example, configure the second laminated module 20 including the plurality of wiring materials 21 and the second connector 22 in a flat shape, and thus can make the entire wire harness WH including the second laminated module 20 and the first laminated module 10 thinner.

[0038] Also, in the wire harness WH of the present embodiment, the first laminated module 10 is disposed on the vehicle body panel 110 side of the vehicle 100 with respect to the second laminated module 20, and the second laminated module 20 is laminated on the surface 11a of the flat wiring material 11 opposite to the vehicle body panel 110 in the lamination direction X. With this configuration, the wire harness WH can laminate the first laminated module 10 and the second laminated module 20 more easily, more smoothly, or more stably, for example, compared to the case where the second laminated module 20 is disposed on the vehicle body panel 110 side.

[0039] Also, in the wire harness WH of the present embodiment, the first connector 12 and the second connector 22 can be connected to the control device 40 mounted on the vehicle 100, and the first connector 12 and the second connector 22 are respectively fitted to the connectors 41 and 42 on the control device 40 side in response to the fastening of the fastening member 50 to the vehicle body panel 110 of the control device 40. With this configuration, the wire harness WH functions as an assist bolt, for example, when the fastening member 50 integrally fits the first connector 12 and the second connector 22 with the connectors 41 and 42 on the control device side, and thus the fitting operation of the first connector 12 and the second connector 22 with the connectors 41 and 42 on the control device side can be performed more easily or more smoothly.

[0040] Also, in the wire harness WH of the present embodiment, the flat wiring material 11 has an opening 11g penetrating along the lamination direction X, and the second connector 22 has a leg portion 22a protruding along the lamination direction X and abutting against the vehicle body panel 110 through the opening 11g. With this configuration, the wire harness WH can position the second connector 22 with respect to the flat wiring material 11 by the engagement between the opening 11g and the leg portion 22a, and can suppress the influence (damage) on the flat wiring material 11 that occurs when the second connector 22 is fitted to the connector 42 on the control device 40 side.

[0041] Also, in the wire harness WH of the present embodiment, the second connector 22 includes a housing 22A that covers the plurality of wire routing members 21 from one side in the stacking direction X, and an under cover 22B that covers the plurality of wire routing members 21 from the other side in the stacking direction X and has both sides in the extending direction Y open. With this configuration, the wire harness WH can, for example, draw out the plurality of wire routing members 21 from either direction on both sides in the extending direction Y by the under cover 22B, and thus parts can be shared in a plurality of specifications with different drawing-out directions of the plurality of wire routing members 21.

[0042] In the present embodiment, the case where the first stacked module 10 is arranged on the vehicle body panel 110 side is illustrated, but it is not limited to this example. For example, the second stacked module 20 may be arranged on the vehicle body panel 110 side, and the flat wire routing member 11 of the first stacked module 10 may be stacked on the plurality of wire routing members 21 of the second stacked module 20. Also, in the present embodiment, the case where the wire harness WH is attached to the resin-made vehicle body panel 110 is illustrated, but it is not limited to this example. For example, it may be attached to a dash panel main body 125 made of metal or a panel other than the dash panel 120 (such as a door panel, a roof panel, a floor panel, etc.).

[0043] As described above, embodiments of the present invention have been illustrated, but the above embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Also, each configuration, shape, etc. of the specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
