[0042] 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 described below. In addition, the constituent elements in the embodiments described below include elements that can be easily replaced by those skilled in the art, or substantially the same elements. In addition, in this specification, ordinal numbers are only used to distinguish components, parts, parts, positions, directions, etc., and do not indicate order or priority.

[0043] [Implementation Method]

[0044] Figure 1 It is a perspective view of a vehicle 100 to which the wire harness WH according to the embodiment is applied. Figure 1 The wire harness WH of the present embodiment shown is applied to a vehicle 100, and is used to connect various devices mounted on the vehicle 100 and to supply power and communicate signals. The wire harness WH of the present embodiment is provided, for example, on a dash panel 120 of the vehicle 100, and is provided inside an instrument panel (not shown) of the vehicle 100. The dash panel 120 is a partition wall that separates an engine room 130 of the vehicle 100 from the interior of the vehicle (cab), and constitutes a structural member (frame member) of the vehicle 100.

[0045] Here, in the present embodiment, the dash panel 120 is configured to include, for example, a dash panel body 125 made of metal and a body panel 110 made of resin. Furthermore, in the present embodiment, the dash panel body 125 is integrally formed with the peripheral panel 115 of the engine room 130 and the like. Thus, the rigidity and strength of the dash panel 120 can be improved, and the body panel 110 can be formed of a resin molded product. That is, in the present embodiment, the body panel 110 is formed of a component different from the dash panel body 125. The body panel 110 is, for example, provided in a recess 121 formed in the dash panel body 125, and together with the dash panel body 125, it constitutes a part of the dash panel 120.

[0046] In addition, in the following description, the first direction among the mutually intersecting first direction, second direction and third direction is referred to as "stacking direction X", the second direction is referred to as "extension direction Y", and the third direction is referred to as "width direction Z". Here, the stacking direction X, the extension direction Y and the width direction Z are substantially orthogonal to each other. The stacking direction X generally corresponds to the stacking direction of the first stacking module 10 and the second stacking module 20 of the wiring harness WH, etc., and is along the front-rear direction of the vehicle. The extension direction Y generally corresponds to the length direction (extension direction) of the flat wiring material 11 of the wiring harness WH, etc., and is along the width direction of the vehicle. The width direction Z generally corresponds to the short side direction of the flat wiring material 11 of the wiring harness WH, etc., and is along the height direction of the vehicle. In addition, unless otherwise specified, the directions used in the following description are described in terms of the directions in which the wiring harness WH is assembled in the vehicle 100.

[0047] Figure 2 This is a three-dimensional diagram of the wiring harness WH. Figure 3 This is an exploded perspective view of the wiring harness WH. Figure 2 , Figure 3 As shown, the wire harness WH of this embodiment includes, for example, a first stacking module 10 and a second stacking module 20. The first stacking module 10 includes a flat wiring material 11 extending along an extension direction Y and a plurality of first connectors 12 provided on a surface 11a of the flat wiring material 11. Here, the first stacking module 10 is connected to a first ECU 40A (see FIG. 4 ) of the control device 40 via the first connector 12 provided at an end 10b on one side of the extension direction Y. Figure 1 ) is connected, and is connected to the second ECU 40E of the control device 40 via another first connector 12 provided at the end 10b on the other side of the extension direction Y.

[0048] It should be noted that the first ECU 40A and the second ECU 40E are generally area ECUs that uniformly control the devices in the peripheral area (ゾーン) of the front panel 120, but are not limited to this. In addition, a plurality of devices 40B to 40D such as other ECUs of the control device 40 are provided between the first ECU 40A and the second ECU 40E. The device 40B is electrically connected to the flat wiring material 11 via the first connector 12 provided in the center of the extension direction Y of the first stacking module 10, and the device 40D is electrically connected to the flat wiring material 11 via another first connector 12 provided in the center of the extension direction Y of the first stacking module 10.

[0049] like Figure 2 and 3As shown, the flat wiring material 11 is a wiring material constituting the wire harness WH, and is composed of, for example, FPC (Flexible Printed Circuits), FFC (Flexible Flat Cable), etc. The flat wiring material 11 is a thin and flexible flat wiring material. The flat wiring material 11 is formed as a whole in a rectangular plate shape that is long in the horizontal direction of the extension direction Y. The flat wiring material 11 is configured to include, for example, a base film, a wiring pattern, and a cover layer.

[0050] The base film is a substrate having excellent flexibility and defining the overall shape of the flat wiring material 11. The base film is formed of, for example, a polyimide resin having excellent heat resistance. The wiring pattern is laminated on the surface (mounting 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 material such as copper foil and is printed on the surface of the base film as a printed circuit body. The cover layer is laminated 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.

[0051] The flat wiring material 11 includes, for example, four first connectors 12. In the flat wiring material 11, one first connector 12 is provided at each of the ends 11b on both sides in the extension direction Y, and two first connectors 12 are provided at one end in the width direction Z. These first connectors 12 are connected to the control device 40 via the connector 41 (see Figure 4 ) is connected to the control device 40.

[0052] In addition, the plurality of first connectors 12 are connected to the wiring pattern of the flat wiring material 11. The plurality of conductor circuit portions formed by the wiring pattern can function as any one of a signal circuit, a signal GND circuit, a power grounding circuit, etc., for example. The signal circuit is a circuit for transmitting communication signals between the control device 40 and various electronic devices in the vehicle 100 and other on-board devices. The signal GND circuit is a circuit that is attached to the signal circuit and is connected between the on-board devices, and makes the potential that serves as the reference for circuit operation consistent between the on-board devices. The power grounding circuit is a circuit that grounds the power supply system of the on-board device.

[0053] The second stacked module 20 is a wiring module stacked on the first stacked module 10. The second stacked module 20 is configured to include a plurality of wiring materials 21 having conductivity and a plurality of second connectors 22 provided at the ends of the plurality of wiring materials 21. Here, the second stacked module 20 has, for example, four second connectors 22 and is stacked on the surface 11a of the flat wiring material 11. The second stacked module 20 is connected to the first ECU 40A (see FIG. 4A ) of the control device 40 via the second connector 22 provided at the end 10b on one side of the extension direction Y. Figure 1 ) is connected, and is connected to the second ECU 40E of the control device 40 via another second connector 22 provided at the end 10b on the other side of the extension direction Y.

[0054] In addition, among the multiple devices 40B~40D arranged between the first ECU40A and the second ECU40E, for example, the device 40C is electrically connected to the multiple wiring materials 21 via the second connector 22 set in the central part of the extension direction Y of the second stack module 20, and the device 40D is electrically connected to the multiple wiring materials 21 via another second connector 22 set in the central part of the extension direction Y of the second stack module 20.

[0055] For example, the plurality of wiring materials 21 are special wires that transmit signals or power that are difficult to properly transmit in the flat wiring material 11, and the plurality of wiring materials 21 are composed of high-speed communication lines for transmitting high-speed communication signals, power lines (thick wires) for transmitting large current power, and the like. In other words, the plurality of wiring materials 21 are composed of wiring materials 21 that cannot ensure the same performance (shielding performance) as high-speed communication lines if placed inside the flat wiring material 11, or wiring materials 21 that would be enlarged like thick wires, and the like. The plurality of wiring materials 21 are each configured to include a linear conductor portion (see Figure 6 ) and an insulating coating covering the outside of the conductor. In the case of a high-speed communication line, for example, the plurality of wiring materials 21 are composed of shielded wires whose outsides of the insulating coating are further covered by a shielding material such as a braid.

[0056] Figure 4 1 is a perspective view showing a 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. Figure 5 2 is a schematic exploded perspective view of the vicinity of the second connector 22 of the wire harness WH. Figure 4 and Figure 5 As shown, in this embodiment, a plurality of wiring materials 21 are arranged in a plane along the surface 11a of the flat wiring material 11. The second stacking module 20 has a fixed lateral width in the width direction Z by virtue of the plurality of wiring materials 21 arranged along the width direction Z, and is configured to be thin and flat in the stacking direction X.

[0057] Here, in the present embodiment, the second stacking module 20 is stacked on the first stacking module 10 along the stacking direction X in a state where both the second connector 22 and the first connector 12 face one side of the stacking direction X. Specifically, in the present embodiment, the first connector 12 and the second connector 22 face the inner side of the vehicle interior (the control device 40 side) on the side opposite to the above-mentioned vehicle body panel 110 in the stacking direction X. The first connector 12 can be connected to the connector 41 on the side of the control device 40 such as the first ECU 40A, and the second connector 22 can be connected to the connector 42 on the side of the control device 40 such as the first ECU 40A. In this way, the first connector 12 and the second connector 22 are arranged in a state of waiting for pairing with respect to the control device 40 such as the first ECU 40A.

[0058] In the present embodiment, the first stacking module 10 is provided with an opening 11g (see FIG. 1 ) penetrating the flat wiring material 11 along the stacking direction X. Figure 5 ). For example, a pair of openings 11g are provided at both ends of the flat wiring material 11 in the width direction Z. Furthermore, the second connector 22 has a pair of legs 22a that protrude toward the other side in the stacking direction X and are inserted into the openings 11g of the flat wiring material 11, respectively. The second connector 22 is positioned relative to the flat wiring material 11 by the engagement between the pair of legs 22a and the pair of openings 11g. In addition, the second connector 22 is connected to the vehicle body panel 110 (see FIG. 1 ) by the legs 22a through the openings 11g. Figure 6 )Abutment status setting.

[0059] Figure 6 4 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. Figure 6 As shown, in the present embodiment, the first stacking module 10 is arranged on the vehicle body panel 110 side relative to the second stacking module 20, and the second stacking module 20 is stacked on the surface 11a of the flat wiring material 11 on the side opposite to the vehicle body panel 110 in the stacking direction X. That is, the second stacking module 20 is arranged on the inner side of the vehicle interior (the control device 40 side) relative to the first stacking module 10, and the first connector 12 and the second connector 22 face the inner side of the vehicle interior (the control device 40 side) on the side opposite to the vehicle body panel 110.

[0060] Here, in the present embodiment, the control device 40 and the vehicle body panel 110 are fastened by the fastening member 50, so that the first connector 12 and the second connector 22 are fitted with the above-mentioned connectors 41 and 42 on the control device 40 side. Specifically, in the present embodiment, the fastening member 50 is configured to include a bolt 51 and a nut 52, and a flange is provided on the control device 40, and the flange is formed with a through hole for inserting the bolt 51 along the stacking direction X. The bolt 51 is installed in a state where, for example, the head 51a is locked to the outer surface (the surface on the opposite side to the first stacking module 10) of the vehicle body panel 110 and the shaft 51b penetrates the vehicle body panel 110.

[0061] The bolt 51 protrudes from the vehicle body panel 110 toward one side (control device 40 side) in the stacking direction X, and is fastened with the nut 52 in a state of being inserted into a through hole formed in the flange of the control device 40. Thus, the bolt 51 functions as an auxiliary bolt when the first connector 12 and the second connector 22 are fitted with the connectors 41 and 42 on the control device 40 side, thereby making it easier or smoother to fit the first connector 12 and the second connector 22 with the connectors 41 and 42 on the control device 40 side. For example, a pair of fastening members 50 and flanges are provided on both sides in the width direction Z so as to sandwich the first connector 12 and the second connector 22.

[0062] Figure 7 is an exploded perspective view of the second connector 22 on the other side of the extending direction Y of the wire harness WH, Figure 8 yes Figure 7 A perspective view of the second connector 22. Figure 7 , Figure 8 As shown, the second connector 22 is configured to include, for example, a housing 22A, a bottom cover 22B, and a plurality of connector terminals 23, 24. The housing 22A covers the plurality of wiring materials 21 and the plurality of connector terminals 23, 24 from one side of the stacking direction X, and the bottom cover 22B covers the plurality of wiring materials 21 and the plurality of connector terminals 23, 24 from the other side of the stacking direction X. The housing 22A and the bottom cover 22B are formed of, for example, a synthetic resin having insulating properties.

[0063] 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 electrically connected to the terminals of the connector 42 on the control device 40 side and an electric wire connection portion electrically connected to the conductor portion at the end of the wiring material 21. The connector terminal 23 is, for example, a connector terminal of the LVDS (Low Voltage Differential Signaling) standard, and the connector terminal 24 is a connector terminal of a different standard from the connector terminal 23.

[0064] 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 dividing the insertion space portions 22e and 22f of the housing 22A. The insertion space portions 22e and 22f are space portions for the above-mentioned connector terminals 23 and 24 to be 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 maintained in a state of being separated from each other by the housing 22A in the width direction Z.

[0065] The bottom cover 22B is configured to include, for example, a lower wall portion 22g and a pair of end wall portions 22h. The bottom cover 22B covers the plurality of wiring materials 21 and the connector terminals 23 and 24 from the other side of the stacking direction X and the two sides of the width direction Z through the lower wall portion 22g and the pair of end wall portions 22h, and the two sides of the extension direction Y of the bottom cover 22B are open. In addition, a recess 22i for holding the plurality of wiring materials 21 and the connector terminals 23 and 24 is provided in the lower wall portion 22g. The recess 22i is recessed in two stages along the outer shape of the plurality of wiring materials 21 and the connector terminals 23 and 24. In addition, a pair of end wall portions 22h are provided with a locking hole 22j for locking the claw portion provided on the inner surface of the pair of end wall portions 22d of the housing 22A. The bottom cover 22B is integrated with the housing 22A by a so-called snap-fit ​​based on the locking of the locking hole 22j and the claw portion.

[0066] Fig. 9 FIG. 2 is an exploded perspective view of the second connector 22 on one side of the extension direction Y of the wire harness WH. Fig. 9 As shown, in this embodiment, both sides of the bottom cover 22B in the extension direction Y are open. Therefore, the plurality of wiring materials 21 can be led out from any direction on both sides of the extension direction Y relative to the bottom cover 22B, and the second connector 22 on the other side of the extension direction Y of the wiring harness WH and the second connector 22 on one side of the extension direction Y, which have different lead-out directions, can use the same bottom cover 22B. Fig. 9 In the figure, for convenience, the illustration of the housing 22A of the second connector 22 is omitted.

[0067] As described above, the second stacked module 20 of the present embodiment includes a plurality of wiring materials 21 and a second connector 22. According to this structure, for example, the wiring materials 21 and the like can be gathered together by the second connector 22, and if the wiring materials 21 enter the interior of the flat wiring material 11, the performance (shielding performance) cannot be ensured like the high-speed communication line, and thus, compared with the conventional structure in which a plurality of high-speed communication lines are connected to the control device 40 individually, the connection operation to the control device 40 can be performed more easily, more smoothly or more quickly.

[0068] The wire harness WH of the present embodiment includes a flat wiring material 11. Therefore, the wire harness WH composed of the flat wiring material 11 is lightweight compared to a general wire harness in which various wires are bundled together. Here, in the case where the wire harness WH is set 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 composed entirely of wires, the overall weight of the wire harness WH may increase. In this regard, according to the present embodiment, the wire harness WH is constructed to include the flat wiring material 11, so that the increase in the overall weight of the wire harness WH can be suppressed, and the enlargement of the wire harness WH can be coped with.

[0069] In addition, usually, a wire harness in which various electric wires are bundled is manufactured by manual labor of an operator. In contrast, since the flat wiring material 11 can be manufactured by automation, the manufacturing man-hours of the wire harness WH can be reduced by making the wire harness WH consist of the flat wiring material 11. In addition, usually, a large wire harness in which various electric wires are bundled is difficult to transport due to its weight. In contrast, according to the present embodiment, by using the flat wiring material 11, there are advantages such as shortening the manufacturing days of the wire harness WH itself or the vehicle 100 using the wire harness WH, or making it difficult to limit the manufacturing site.

[0070] As described above, the wire harness WH of the present embodiment includes: a first stacking module 10 including a flexible flat wiring material 11 and a first connector 12 provided on the flat wiring material 11; and a second stacking module 20 including a plurality of conductive wiring materials 21 and a second connector 22 provided on the plurality of wiring materials 21, the second stacking module 20 being stacked on the first stacking module 10 along the stacking direction X in a state where the second connector 22 and the first connector 12 face one side of the stacking direction X intersecting the extending direction Y of the flat wiring material 11. According to this configuration, the wire harness WH can, for example, stack the second stacking module 20 relative to the first stacking module 10 along the stacking direction X in a state where both the second connector 22 and the first connector 12 face one side of the stacking direction X. As a result, the wire harness WH can improve the ease of assembly into the vehicle 100.

[0071] In addition, in the wiring harness WH of this embodiment, the plurality of wiring materials 21 are composed of communication lines for transmitting signals or power lines for transmitting power, and are arranged in a plane. According to this structure, the wiring harness WH can, for example, make the second stacking module 20 including the plurality of wiring materials 21 and the second connector 22 into a flat shape, thereby further thinning the entire wiring harness WH including the second stacking module 20 and the first stacking module 10.

[0072] In the wire harness WH of the present embodiment, the first stacking module 10 is arranged on the vehicle body panel 110 side of the vehicle 100 relative to the second stacking module 20, and the second stacking module 20 is stacked on the surface 11a of the flat wiring material 11 on the side opposite to the vehicle body panel 110 in the stacking direction X. According to this configuration, the wire harness WH can stack the first stacking module 10 and the second stacking module 20 more easily, smoothly or stably, compared with the case where the second stacking module 20 is arranged on the vehicle body panel 110 side.

[0073] In addition, 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 engaged with the connectors 41 and 42 on the side of the control device 40 by fastening the control device 40 and the vehicle body panel 110 using the fastening member 50. According to this structure, in the wire harness WH, for example, the fastening member 50 functions as an auxiliary bolt when the first connector 12 and the second connector 22 are engaged with the connectors 41 and 42 on the side of the control device, and the engagement operation of the first connector 12 and the second connector 22 with the connectors 41 and 42 on the side of the control device can be performed more easily or more smoothly.

[0074] In addition, in the wire harness WH of the present embodiment, the flat wiring material 11 has an opening 11g that penetrates along the stacking direction X, and the second connector 22 has a leg 22a that protrudes along the stacking direction X and abuts against the vehicle body panel 110 via the opening 11g. With this structure, the wire harness WH can position the second connector 22 relative to the flat wiring material 11 by, for example, engaging the opening 11g with the leg 22a, and can suppress the influence (damage) on the flat wiring material 11 generated when the second connector 22 is engaged with the connector 42 on the control device 40 side.

[0075] In addition, in the wire harness WH of the present embodiment, the second connector 22 is configured to include: a housing 22A that covers the plurality of wiring materials 21 from one side of the stacking direction X; and a bottom cover 22B that covers the plurality of wiring materials 21 from the other side of the stacking direction X and is open on both sides of the extension direction Y. According to this structure, the wire harness WH can, for example, lead out the plurality of wiring materials 21 from any direction on both sides of the extension direction Y through the bottom cover 22B, and can further use a common component with a plurality of specifications in which the lead-out directions of the plurality of wiring materials 21 are different.

[0076] It should be noted that, in the present embodiment, the case where the first stacking module 10 is arranged on the vehicle body panel 110 side is illustrated, but the present invention is not limited to this example, and for example, the second stacking module 20 may be arranged on the vehicle body panel 110 side, and the flat wiring material 11 of the first stacking module 10 may be stacked on the plurality of wiring materials 21 of the second stacking module 20. In addition, in the present embodiment, the case where the wire harness WH is mounted on the resin vehicle body panel 110 is illustrated, but it is not limited to this example, and for example, it may be mounted on a metal dash panel body 125 or a panel other than the dash panel 120 (door panel, roof panel, floor panel, etc.).

[0077] The above examples illustrate the embodiments of the present invention, but the above embodiments are only examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other ways, and various omissions, substitutions, combinations, and changes can be made without departing from the scope of the main purpose of the invention. In addition, the specifications of various structures, shapes, etc. (structure, type, direction, form, size, length, width, thickness, height, quantity, configuration, position, material, etc.) can be appropriately changed and implemented.
