[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring member of the present disclosure is as follows.

[0011] (1) A wiring member including a plurality of linear transmission members, the plurality of linear transmission members being grouped into at least a plurality of first linear transmission members and a plurality of second linear transmission members according to predetermined conditions related to the plurality of linear transmission members, and including a first flat wiring member including the plurality of first linear transmission members and a second flat wiring member including the plurality of second linear transmission members, wherein at least a portion of the first flat wiring member and at least a portion of the second flat wiring member are stacked. According to the present disclosure, since a plurality of linear transmission members of the same group are included in the same flat wiring member, it is easy to manufacture a wiring member including stacked first and second flat wiring members.

[0012] (2) The plurality of linear transmission members may be grouped into at least the plurality of first linear transmission members and the plurality of second linear transmission members according to their connection destinations, which makes it easier to route the stacked first and second flat wiring members.

[0013] (3) The plurality of linear transmission members may be grouped into at least the plurality of first linear transmission members and the plurality of second linear transmission members according to the types of the plurality of linear transmission members. In this case, linear transmission members of the same type can be included in the same flat wiring member, which makes it easier to manufacture a wiring member including stacked first and second flat wiring members.

[0014] (4) The plurality of first linear transmission members may include power lines or ground lines, and the plurality of second linear transmission members may include signal lines. In this case, the signal lines are included in a flat wiring member separate from the power lines or ground lines through which a relatively large current flows, so the signal lines are less susceptible to the influence of the power lines or ground lines. As a result, noise is less likely to occur in the signal lines.

[0015] (5) The plurality of first linear transmission members may be connected to at least one standard component of the vehicle, and the plurality of second linear transmission members may be connected to at least one optional component of the vehicle. In this case, the optional component is connected to a linear transmission member included in a flat wiring member separate from the standard component. Therefore, when fabricating the wiring member, it is possible to easily accommodate the presence or absence of the optional component. This makes it easier to fabricate the wiring member.

[0016] (6) The plurality of first linear transmission members may be connected to at least one first connection target portion located in a first area, and the plurality of second linear transmission members may be connected to at least one second connection target portion located in a second area different from the first area. In this case, the linear transmission members of the first and second flat wiring members are connected to connection target portions located in different areas, making it easier to route the stacked first and second flat wiring members.

[0017] (7) The plurality of first linear transmission members may include at least one linear transmission member that exhibits a color that allows the first flat wiring member and the second flat wiring member to be distinguished from each other. In this case, the first flat wiring member and the second flat wiring member can be distinguished from each other, and therefore the first and second flat wiring members can be stacked accurately in the laminating process.

[0018] (8) The plurality of first linear transmission members may include at least one linear transmission member that exhibits a color different from that of at least one of the plurality of second linear transmission members. In this case, the first flat wiring member and the second flat wiring member can be easily distinguished from each other, and therefore the first and second flat wiring members can be accurately stacked in the laminating process.

[0019] (9) The plurality of first linear transmission members may include at least one linear transmission member that exhibits a color different from that of each of the plurality of second linear transmission members. In this case, the first flat wiring member and the second flat wiring member can be more easily distinguished from each other, and therefore, the first and second flat wiring members can be stacked accurately in the laminating process.

[0020] (10) The first flat wiring member has a bending portion around which the plurality of third linear transmission members included in the plurality of first linear transmission members bend, and the third linear transmission member with the smallest diameter among the plurality of third linear transmission members is located innermost at the bending portion. In this case, the bending radius of the third linear transmission member with a larger outer diameter than the third linear transmission member with the smallest diameter can be made larger at the bending portion. This makes it easier to bend the third linear transmission member with a larger diameter.

[0021] (11) At the bending portion, the plurality of third linear transmission members are arranged so that the larger the diameter of the third linear transmission members, the more outwardly they are positioned. In this case, the larger the diameter of the third linear transmission members, the larger the bending radius of the third linear transmission members can be. Therefore, the plurality of third linear transmission members become easier to bend.

[0022] [Details of the embodiments of the present disclosure] Specific examples of wiring members according to the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0023] A wiring member according to an embodiment will now be described. FIG. 1 is a schematic plan view showing the wiring member 1. The wiring member 1 includes a plurality of stacked flat wiring members 10. The plurality of flat wiring members 10 are, for example, members that connect a plurality of components mounted on an automobile vehicle. In this example, the wiring member 1 includes three stacked flat wiring members 10A, 10B, and 10C. The number of stacked flat wiring members 10 included in the wiring member 1 may be two, or may be four or more. At least one of the plurality of flat wiring members 10 included in the wiring member 1 may be branched or bent. In the example of FIG. 1, both the flat wiring members 10B and 10C are bent.

[0024] The wiring member 1 has a laminated portion 2 in which flat wiring members 10A, 10B, and 10C are laminated. In the laminated portion 2, at least a portion of the flat wiring member 10A, at least a portion of the flat wiring member 10B, and at least a portion of the flat wiring member 10C are laminated. In the laminated portion 2 of this example, a portion of the flat wiring member 10A, a portion of the flat wiring member 10B, and a portion of the flat wiring member 10C are laminated.

[0025] FIG. 2 is a schematic cross-sectional view of the laminated portion 2. Each flat wiring member 10 includes a plurality of linear transmission members 11 and a sheet 12. The linear transmission members 11 are linear members that transmit electricity, light, or the like. In this example, the linear transmission members 11 are electric wires including a core wire and an insulating coating that covers the core wire. The core wire is a linear conductor formed of a conductive material such as metal. The core wire is composed of one or more strands. The insulating coating is an insulating portion that covers the periphery of the core wire. The linear transmission members 11 may be bare wires, shielded wires, twisted wires, enameled wires, nichrome wires, optical fibers, or the like, in addition to electric wires. In the example of FIG. 2, the plurality of linear transmission members 11 have the same diameter.

[0026] The sheet 12 is a sheet-like member that keeps the multiple linear transmission members 11 in a flat form. The sheet 12 is formed from resin or the like. The sheet 12 may contain metal. The sheet 12 may contain a nonwoven sheet. The multiple linear transmission members 11 are fixed in a parallel state to one main surface of the sheet 12. The linear transmission members 11 are fixed to the sheet 12 by welding, bonding, adhesion, or the like. The welding may be ultrasonic welding or heat welding. By fixing the multiple linear transmission members 11 to one main surface of the sheet 12, the multiple linear transmission members 11 are kept in a flat state.

[0027] The flat wiring member 10 is not limited to the above example. The plurality of linear transmission members 11 may be held in a flat state by a flat frame member or the like. The plurality of linear transmission members 11 may be directly joined in a parallel arrangement so as to form a flat shape. The flat wiring member 10 may also be a wiring member in which a plurality of linear conductors are held in a flat state while being insulated from one another by an insulating member, such as an FCC (Flexible Flat Cable) or an FPC (Flexible Printed Circuit). In other words, the flat wiring member 10 may be a wiring member in which a plurality of linear conductors are held in a flat state while being insulated from one another, and which is formed so that its overall thickness is smaller than its width.

[0028] 2, in the laminated portion 2, flat wiring members 10A, 10B, and 10C are laminated in this order. The plurality of linear transmission members 11 of the flat wiring member 10A overlaps with the sheet 12 of the flat wiring member 10B, and the plurality of linear transmission members 11 of the flat wiring member 10B overlaps with the sheet 12 of the flat wiring member 10C.

[0029] The flat wiring member 10 may include a plurality of linear transmission members 11 having different diameters. In the example of Fig. 3, the flat wiring members 10A and 10B each include a linear transmission member 11a having a relatively large diameter and a linear transmission member 11b having a relatively small diameter. The flat wiring member 10C does not include a linear transmission member 11a having a relatively large diameter, but includes a linear transmission member 11b having a relatively small diameter. In the example of Fig. 3, the plurality of linear transmission members 11 included in the flat wiring member 10 include two types of diameters, but may include three or more types.

[0030] Furthermore, in two stacked flat wiring members 10, the plurality of linear transmission members 11 of one flat wiring member 10 may overlap with the plurality of linear transmission members 11 of the other flat wiring member 10. In the example of Fig. 3, the plurality of linear transmission members 11 of the flat wiring member 10A overlap with the plurality of linear transmission members 11 of the flat wiring member 10B.

[0031] In the example of Fig. 2, in a cross-sectional view of the laminated portion 2, the boundary line between the two laminated flat wiring members 10 is straight, but it may be curved. Figs. 3 to 5 are diagrams showing examples of the cross-sectional structure of the laminated portion 2 when the boundary line between the two laminated flat wiring members 10 is curved.

[0032] In the example of Fig. 3, a recessed space is created in the flat wiring member 10A by the small-diameter linear transmission member 11b included in the flat wiring member 10A. Furthermore, a protruding portion is created in the flat wiring member 10B by the large-diameter linear transmission member 11a included in the flat wiring member 10B. The protruding portion of the flat wiring member 10B is disposed within the recessed space of the flat wiring member 10A. As a result, the boundary line 20 between the two stacked flat wiring members 10A and 10B is curved rather than straight.

[0033] 4, the sheet 12 is flexibly deformable, and the sheet 12 of the flat wiring member 10B deforms in accordance with the recessed space created by the small-diameter linear transmission member 11b included in the flat wiring member 10A. As a result, the boundary line between the two stacked flat wiring members 10A and 10B is curved rather than straight.

[0034] In the example of Figure 5, the boundary line 20 is curved by arranging multiple linear transmission members 11b included in the flat wiring member 10B in a recessed space created by bending both widthwise ends of the flat wiring member 10A in the same direction.

[0035] The laminated portion 2 may include all of the flat wiring member 10A. That is, the laminated portion 2 may include all of the flat wiring member 10A, at least a portion of the flat wiring member 10B, and at least a portion of the flat wiring member 10C stacked together. The laminated portion 2 may also include all of the flat wiring member 10B or all of the flat wiring member 10C. The laminated portion 2 may also have curved portions.

[0036] The flat wiring member 10 may also include a connector connected to at least one end of at least one of the plurality of linear transmission members 11 included therein. The wiring member 10 may also include a stacked connector. In this case, the stacked connector may include a connector to which at least one linear transmission member 11 of the flat wiring member 10A is connected, a connector to which at least one linear transmission member 11 of the flat wiring member 10B is connected, and a connector to which at least one linear transmission member 11 of the flat wiring member 10C is connected.

[0037] The structure for maintaining the plurality of flat wiring members 10 in a stacked state in the laminated portion 2 is not particularly limited. For example, a configuration in which a binding member such as adhesive tape is wrapped around the periphery of the laminated portion 2 may be employed. Alternatively, the plurality of flat wiring members 10 may be bonded with an adhesive or double-sided tape interposed therebetween. Alternatively, the sheets 12 on both sides of the plurality of flat wiring members 10 may be joined by welding, adhesive tape, or adhesive, or may be maintained in an overlapping state by clamps or the like.

[0038] Here, the plurality of linear transmission members 11 included in the wiring member 1 are divided into a plurality of groups according to predetermined conditions related to the plurality of linear transmission members 11. In this example, the plurality of linear transmission members 11 included in the wiring member 1 are divided into a first group including a plurality of linear transmission members 11, a second group including a plurality of linear transmission members 11, and a third group including a plurality of linear transmission members 11. The flat wiring member 10A includes a plurality of linear transmission members 11 in the first group, the flat wiring member 10B includes a plurality of linear transmission members 11 in the second group, and the flat wiring member 10C includes a plurality of linear transmission members 11 in the third group. The plurality of linear transmission members 11 included in the wiring member 1 may be divided into two groups, or four or more groups.

[0039] In this way, in this example, for a plurality of stacked flat wiring members 10, a plurality of linear transmission members 11 of the same group are included in the same flat wiring member 10. This makes it easier to manufacture a wiring member 1 including a plurality of stacked flat wiring members 10.

[0040] The plurality of linear transmission members 11 included in the wiring member 1 are divided into, for example, a first group, a second group, and a third group according to the connection destinations of the plurality of linear transmission members 11. Below, an example of the connection destinations of each flat wiring member 10 when the plurality of linear transmission members 11 included in the wiring member 1 are grouped according to the connection destinations will be described.

[0041] The wiring member 1 is connected to, for example, a plurality of connection target parts in a vehicle. The plurality of connection target parts to which the wiring member 1 is connected are divided into a plurality of connection target groups 30. The plurality of connection target groups 30 include, for example, a connection target group 30A including at least one connection target part, a connection target group 30B including at least one connection target part, and a connection target group 30C including at least one connection target part (see FIG. 1 ).

[0042] The plurality of linear transmission members 11 included in the wiring member 1 are divided into a first group including a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30A, a second group including a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30B, and a third group including a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30C. Thus, the flat wiring member 10A includes a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30A, the flat wiring member 10B includes a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30B, and the flat wiring member 10C includes a plurality of linear transmission members 11 connected to the connection target portions of the connection target group 30C.

[0043] One ends of the plurality of linear transmission members 11 included in the flat wiring member 10A are connected to at least one connection target portion included in the connection target group 30A. One ends of the plurality of linear transmission members 11 included in the flat wiring member 10B are connected to at least one connection target portion included in the connection target group 30B. One ends of the plurality of linear transmission members 11 included in the flat wiring member 10C are connected to at least one connection target portion included in the connection target group 30C. The number of the plurality of connection target groups 30 may be two, or may be four or more.

[0044] In this way, in this example, the plurality of stacked flat wiring members 10 are connected to the plurality of different connection target groups 30, respectively. That is, for each of the plurality of stacked flat wiring members 10, the plurality of linear transmission members 11 included in the flat wiring member 10 can be connected to the connection target portions of the same connection target group 30. This makes it easier to route each of the plurality of stacked flat wiring members 10. An example of grouping the plurality of connection target portions will be described below.

[0045] Fig. 6 is a diagram illustrating an example of grouping. In the example of Fig. 6, the connection target group 30A includes connection target parts that output power to circuits mounted on a vehicle. For example, the connection target group 30A includes a power supply box 130A. In this example, each linear transmission member 11 of the flat wiring member 10A is a power line.

[0046] The connection target group 30B includes connection target portions for grounding each linear transmission member 11 of the flat wiring member 10B. For example, the connection target group 30B includes a grounded metal body 130B. In this example, each linear transmission member 11 of the flat wiring member 10A serves as a ground line.

[0047] The connection target group 30C includes a connection target part that receives and outputs a signal or receives a signal. For example, the connection target group 30C includes a controller 130C. In this example, each linear transmission member 11 of the flat wiring member 10C is a signal line. The controller 130C includes, for example, an ECU (Electronic Control Unit).

[0048] One ends of the plurality of linear transmission members 11 of the flat wiring member 10A are connected to a power supply box 130A. In this example, a connector 13A is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10A. The connector 13A is connected to a connector 131A of the power supply box 130A. As a result, power output from the power supply box 130A is supplied to each linear transmission member 11 of the flat wiring member 10A.

[0049] One ends of the plurality of linear transmission members 11 of the flat wiring member 10B are connected to the metal body 130B. In this example, a ground terminal 13B is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10B. The ground terminal 13B is fixed to the metal body 130B by screws or the like. As a result, each linear transmission member 11 of the flat wiring member 10B is grounded.

[0050] One ends of the plurality of linear transmission members 11 of the flat wiring member 10C are connected to the controller 130C. In this example, a connector 13C is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10C. The connector 13C is connected to a connector 131C of the controller 130C. If the connector 131C includes an output terminal, a signal output by the controller 130C (e.g., a control signal for controlling a circuit) is applied to the linear transmission members 11 of the flat wiring member 10C. If the connector 131C includes an input terminal, a signal transmitted by the linear transmission members 11 of the flat wiring member 10C (e.g., a detection signal from a sensor) is input to the controller 130C.

[0051] A plurality of connection target units may be included in a connection target group. In this case, a plurality of connection target units that are located close to each other may be included in the connection target group.

[0052] For example, the connection target group 30A may include multiple power supply boxes 130A. In this case, the multiple linear transmission members 11 of the flat wiring member 10A may be branched into multiple branch portions, and the multiple branch portions may be connected to the multiple power supply boxes 130A, respectively. Furthermore, the connection target portion that outputs the power included in the connection target group 30A may be something other than the power supply box 130A.

[0053] The connection target group 30B may include a plurality of grounded connection target parts. In this case, the plurality of linear transmission members 11 of the flat wiring member 10B may be branched into a plurality of branch parts, and the plurality of branch parts may be connected to the plurality of grounded connection target parts, respectively.

[0054] The connection target group 30C may include multiple controllers. In this case, the multiple linear transmission members 11 of the flat wiring member 10C may be branched into multiple branch portions, and the multiple branch portions may be connected to multiple controllers, respectively. The connection target group 30C may also include items other than controllers. For example, the connection target group 30C may include at least one sensor that outputs a signal.

[0055] 6, the signal lines are included in a flat wiring member 10 separate from the power lines, through which a relatively large current flows. This makes the signal lines less susceptible to the influence of the power lines, and therefore reduces the generation of noise in the signal lines.

[0056] 6, the signal lines are included in a flat wiring member 10 separate from the ground lines, through which a relatively large current flows. This makes the signal lines less susceptible to the influence of the ground lines, and therefore reduces the generation of noise in the signal lines.

[0057] Fig. 7 is a diagram illustrating another example of grouping. In the example of Fig. 7, the connection target group 30A includes a standard vehicle component 230A. The standard vehicle component 230A is, for example, a room lamp, a hazard lamp, a digital meter that indicates speed, an air conditioner, an airbag mechanism, or the like.

[0058] The connection target group 30B includes optional vehicle items 230B. Here, optional items include not only devices installed on the vehicle in addition to the standard items, but also devices installed in place of the standard items. Optional items are also called optional devices. Examples of devices installed on the vehicle in addition to the standard items include fog lamps, a drive recorder, an ETC (Electronic Toll Collection System) in-vehicle unit, and a backup monitor camera. Examples of devices installed in place of the standard items include a car navigation device with better performance than the standard car navigation device, an audio device with better performance than the standard audio device, or LED (Light Emitting Diode) headlights installed in place of the standard halogen headlights. Optional item 230B may be a device installed on the vehicle in addition to the standard items, or may be a device installed in place of the standard items.

[0059] The connection target group 30C includes an optional item 230C that is different from the optional item 230B. The optional item 230C may be a device that is installed in the vehicle in addition to the standard installed item, or may be a device that is installed in place of the standard installed item. The types of standard installed items and optional items of a vehicle vary depending on the vehicle model, grade, etc.

[0060] One ends of the plurality of linear transmission members 11 of the flat wiring member 10A are connected to the standard-installed component 230A. In this example, a connector 13A is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10A. The connector 13A is connected to a connector 231A of the standard-installed component 230A.

[0061] One ends of the plurality of linear transmission members 11 of the flat wiring member 10B are connected to the optional item 230B. In this example, a connector 13BB is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10B. The connector 13BB is connected to a connector 231B included in the optional item 230B.

[0062] One ends of the plurality of linear transmission members 11 of the flat wiring member 10C are connected to an optional item 230C. In this example, a connector 13C is connected to one ends of the plurality of linear transmission members 11 of the flat wiring member 10C. The connector 13C is connected to a connector 231C included in the optional item 230C.

[0063] The connection target group 30 may include a plurality of standard-installed items. In this case, the connection target group 30 may include a plurality of standard-installed items that are located close to each other. The connection target group 30 may also include a plurality of optional items. In this case, the connection target group 30 may include a plurality of optional items that are located close to each other.

[0064] For example, the connection target group 30A may include a plurality of standard-installed components. In this case, the plurality of linear transmission members 11 of the flat wiring member 10A may be branched into a plurality of branch portions, and the plurality of branch portions may be connected to a plurality of standard-installed components, respectively. Similarly, the connection target group 30B may include a plurality of optional components, and the connection target group 30C may include a plurality of optional components.

[0065] In the wiring member 1 according to the example of FIG. 7, an optional item is connected to the linear transmission member 11 of the flat wiring member 10 that is separate from the standard-installed item. This allows the wiring member 1 to be easily manufactured depending on whether or not the optional item is included. Therefore, the wiring member 1 can be easily manufactured. For example, if the optional item 230C is not included, the flat wiring member 10C is not mounted on the wiring member 1, thereby allowing the wiring member 1 to be easily manufactured depending on whether or not the optional item 230C is included.

[0066] Fig. 8 is a diagram for explaining another example of grouping. Fig. 8 shows how the wiring member 1 is routed on the roof 500 of a vehicle. In the example of Fig. 8, a plurality of connection target parts are grouped according to the areas in which the connection target parts are located.

[0067] The connection target portions included in the connection target group 30A are located in a front area 510 of the roof 500. The connection target group 30A includes, for example, a room lamp located in the front area 510 of the roof 500. One ends of the plurality of linear transmission members 11 of the flat wiring member 10A are connected to the room lamp located in the front area 510. One ends of the plurality of linear transmission members 11 of the flat wiring member 10A may be connected to the plurality of connection target portions located in the front area 510.

[0068] The connection target portions included in the connection target group 30B are located in the central area 520 of the roof 500. The connection target group 30B includes, for example, a room lamp located in the central area 520 of the roof 500. One ends of the plurality of linear transmission members 11 of the flat wiring member 10B are connected to the room lamp located in the central area 520. One ends of the plurality of linear transmission members 11 of the flat wiring member 10B may be connected to the plurality of connection target portions located in the central area 520.

[0069] The connection target portions included in the connection target group 30C are located in the rear area 530 of the roof 500. The connection target group 30C includes, for example, an antenna located in the rear area 530 of the roof 500. One ends of the plurality of linear transmission members 11 of the flat wiring member 10C are connected to the antenna located in the rear area 530. One ends of the plurality of linear transmission members 11 of the flat wiring member 10C may be connected to the plurality of connection target portions located in the rear area 530.

[0070] The positions of the connection target units included in the connection target group 30 are not limited to the above example. For example, the connection target units included in the connection target group 30A may be located on an instrument panel at the front of the vehicle. Also, the connection target units included in the connection target group 30A may be located on a panel at the rear of the vehicle.

[0071] In the wiring member 1 of the example of Figure 8, the linear transmission members 11 of the multiple flat wiring members 10 are connected to connection target portions located in different areas, making it easier to route the stacked multiple flat wiring members 10.

[0072] In the above example, the multiple linear transmission members 11 included in the wiring member 1 are divided into multiple groups according to their connection destinations, but they may also be divided into multiple groups according to other conditions. For example, the multiple linear transmission members 11 included in the wiring member 1 may be divided into multiple groups according to the types of the multiple linear transmission members 11. This allows multiple linear transmission members 11 of the same type to be included in the same flat wiring member 10. This makes it easier to manufacture a wiring member 1 including multiple stacked flat wiring members 10. Several examples of this case will be described below.

[0073] The plurality of linear transmission members 11 included in the wiring member 1 may be divided into a plurality of groups, for example, according to the diameter of the linear transmission members 11. For example, the plurality of linear transmission members 11 included in the wiring member 1 may be divided into a first group including a plurality of linear transmission members 11 with a large diameter, a second group including a plurality of linear transmission members 11 with a medium diameter, and a third group including a plurality of linear transmission members 11 with a small diameter. In this case, the plurality of linear transmission members 11 with a large diameter included in the first group are included in flat wiring member 10A. The plurality of linear transmission members 11 with a medium diameter included in the second group are included in flat wiring member 10B. And the plurality of linear transmission members 11 with a small diameter included in the third group are included in flat wiring member 10C.

[0074] Furthermore, the multiple linear transmission members 11 included in the wiring member 1 may be divided into multiple groups according to the material of the core wire of the linear transmission members 11. In this case, the multiple groups may include, for example, a first group including multiple linear transmission members 11 whose core wire is made of aluminum, and a second group including multiple linear transmission members 11 whose core wire is made of copper. Note that a third group may include, for example, multiple linear transmission members 11 whose core wire has the same diameter.

[0075] Furthermore, the multiple linear transmission members 11 included in the wiring member 1 may be divided into multiple groups according to the shape of the core wire of the linear transmission members 11. In this case, the multiple groups may include, for example, a first group including multiple linear transmission members 11 whose core wire is a twisted wire, and a second group including multiple linear transmission members 11 whose core wire is a solid wire. Note that a third group may include, for example, multiple linear transmission members 11 whose core wire has the same diameter.

[0076] Furthermore, the multiple linear transmission members 11 included in the wiring member 1 may be divided into multiple groups according to the compressibility of the metal constituting the core wire of the linear transmission members 11. For example, the multiple linear transmission members 11 included in the wiring member 1 may be divided into a first group including multiple linear transmission members 11 with a high compressibility of the metal constituting the core wire, a second group including multiple linear transmission members 11 with a medium compressibility of the metal constituting the core wire, and a third group including multiple linear transmission members 11 with a low compressibility of the metal constituting the core wire.

[0077] In addition, if the multiple linear transmission members 11 provided in the wiring member 1 are divided into multiple groups according to the type of linear transmission member 11, the multiple connection target parts to which the wiring member 1 is connected do not need to be divided into multiple connection target groups 30.

[0078] <About the colors shown by linear transmission components> Next, we will explain the color of the linear transmission member 11 provided in the flat wiring member 10, that is, the color of the outer surface of the linear transmission member 11. In this example, the linear transmission member 11 is an electric wire including a core wire and an insulating coating covering the core wire, so the color of the linear transmission member 11 can be said to be the color of the outer surface of the insulating coating covering the core wire.

[0079] The color of the multiple linear transmission members 11 included in the flat wiring member 10 may be the same. In this case, the colors of the linear transmission members 11 among the multiple flat wiring members 10 may be the same or different. In the former case, all the linear transmission members 11 included in the wiring member 10 will be the same color. In this case, the color of each linear transmission member 11 included in the wiring member 1 may be black or another color.

[0080] Fig. 9 is a diagram illustrating an example of the colors of the linear transmission members 11. In Fig. 9 and Fig. 10 described later, for convenience of explanation, the flat wiring members 10A, 10B, and 10C are shown separated and not stacked. In Fig. 9 and Fig. 10 described later, multiple linear transmission members 11 showing the same color are shown with the same hatching, and multiple linear transmission members 11 showing different colors are shown with different hatching.

[0081] In the example of FIG. 9, the multiple linear transmission members 11 of the flat wiring member 10A are the same color. The multiple linear transmission members 11 of the flat wiring member 10B are the same color. The multiple linear transmission members 11 of the flat wiring member 10C are the same color. On the other hand, the colors of the linear transmission members 11 are different among the multiple flat wiring members 10A, 10B, and 10C. The color of each linear transmission member 11 of the flat wiring member 10A is black, for example. The color of each linear transmission member 11 of the flat wiring member 10B is red, for example. The color of each linear transmission member 11 of the flat wiring member 10C is blue, for example.

[0082] Here, attention is focused on the flat wiring member 10A. In the example of Fig. 9, the plurality of linear transmission members 11 of the flat wiring member 10A include linear transmission members 11 that are different in color from the plurality of linear transmission members 11 of the flat wiring member 10B. This makes it possible to distinguish the flat wiring member 10A from the flat wiring member 10B. Therefore, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10A include linear transmission members 11 that are different in color from the plurality of linear transmission members 11 of the flat wiring member 10C. This makes it possible to distinguish the flat wiring member 10A from the flat wiring member 10C. Therefore, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10A include linear transmission members 11 that exhibit colors that allow the flat wiring member 10A and the flat wiring member 10C to be distinguished from each other.

[0083] Similarly, when focusing on the flat wiring member 10B, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10B includes linear transmission members 11 that exhibit colors that allow the flat wiring member 10B to be distinguished from the flat wiring member 10A. It can also be said that the plurality of linear transmission members 11 of the flat wiring member 10B includes linear transmission members 11 that exhibit colors that allow the flat wiring member 10B to be distinguished from the flat wiring member 10C.

[0084] Similarly, when focusing on the flat wiring member 10C, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10C includes linear transmission members 11 that exhibit colors that allow the flat wiring member 10C to be distinguished from the flat wiring member 10A. It can also be said that the plurality of linear transmission members 11 of the flat wiring member 10C includes linear transmission members 11 that exhibit colors that allow the flat wiring member 10C to be distinguished from the flat wiring member 10B.

[0085] Fig. 10 is a diagram illustrating another example of the color of the linear transmission member 11. In the example of Fig. 10, each of the flat wiring members 10A, 10B, and 10C includes a linear transmission member 11c that exhibits a common color among the flat wiring members 10A, 10B, and 10C. The color of the linear transmission member 11c is, for example, black.

[0086] Each of the plurality of flat wiring members 10A, 10B, and 10C includes a linear transmission member 11 that exhibits a color different from the linear transmission members 11 included in the other flat wiring members 10.

[0087] The flat wiring member 10A includes one linear transmission member 11d that is a different color from the linear transmission members 11 included in the flat wiring member 10B and the linear transmission members 11 included in the flat wiring member 10C. The color of the linear transmission member 11d is, for example, red. The flat wiring member 10A may include two or more linear transmission members 11d.

[0088] The flat wiring member 10B includes two linear transmission members 11e that are different in color from the linear transmission members 11 included in the flat wiring member 10A and the linear transmission members 11 included in the flat wiring member 10C. The color of the linear transmission members 11e is, for example, blue. The flat wiring member 10B may include one linear transmission member 11e or three or more linear transmission members 11e.

[0089] The flat wiring member 10C includes three linear transmission members 11f that are a different color from the linear transmission members 11 included in the flat wiring member 10A and the linear transmission members 11 included in the flat wiring member 10B. The color of the linear transmission members 11f is, for example, yellow. The flat wiring member 10B may include fewer than three linear transmission members 11f, or may include four or more linear transmission members 11f.

[0090] Here, attention is focused on the flat wiring member 10A. In the example of FIG. 10, the plurality of linear transmission members 11 of the flat wiring member 10A includes linear transmission members 11d that are a different color from the linear transmission members 11e of the flat wiring member 10B. This makes it possible to distinguish the flat wiring member 10A from the flat wiring member 10B. Therefore, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10A include linear transmission members 11d that are a different color from the linear transmission members 11f of the flat wiring member 10C. This makes it possible to distinguish the flat wiring member 10A from the flat wiring member 10C. Therefore, it can be said that the plurality of linear transmission members 11 of the flat wiring member 10A includes linear transmission members 11d that exhibit colors that allow the flat wiring member 10A and the flat wiring member 10C to be distinguished from each other.

[0091] 10, the plurality of linear transmission members 11 of the flat wiring member 10B can be said to include linear transmission members 11e that exhibit a color that allows the flat wiring member 10B to be distinguished from the flat wiring member 10A. Also, the plurality of linear transmission members 11 of the flat wiring member 10B can be said to include linear transmission members 11e that exhibit a color that allows the flat wiring member 10B to be distinguished from the flat wiring member 10C.

[0092] 10, the plurality of linear transmission members 11 of the flat wiring member 10C can be said to include linear transmission members 11f that exhibit a color that allows the flat wiring member 10C to be distinguished from the flat wiring member 10A. Also, the plurality of linear transmission members 11 of the flat wiring member 10C can be said to include linear transmission members 11f that exhibit a color that allows the flat wiring member 10C to be distinguished from the flat wiring member 10B.

[0093] 10, when the focus is on distinguishing between the flat wiring member 10A and the flat wiring member 10B, all of the linear transmission members 11 included in either the flat wiring member 10A or the flat wiring member 10B may be the same color. Similarly, when the focus is on distinguishing between the flat wiring member 10A and the flat wiring member 10C, all of the linear transmission members 11 included in either the flat wiring member 10A or the flat wiring member 10C may be the same color. Similarly, when the focus is on distinguishing between the flat wiring member 10B and the flat wiring member 10C, all of the linear transmission members 11 included in either the flat wiring member 10B or the flat wiring member 10C may be the same color.

[0094] 9 and 10, in the two stacked flat wiring members 10, the plurality of linear transmission members 11 of one of the flat wiring members 10 includes at least one linear transmission member 11 that displays a color that allows the one flat wiring member 10 to be distinguished from the other flat wiring member 10. This allows the two flat wiring members to be distinguished. As a result, the plurality of flat wiring members 10 can be stacked accurately in the stacking process. For example, it is possible to prevent the plurality of flat wiring members 10 from being stacked in the wrong order or from being stacked with the wrong type of flat wiring members 10.

[0095] Furthermore, as in the above example, when two stacked flat wiring members 10 include at least one linear transmission member 11 of one flat wiring member 10 that is a different color from at least one of the linear transmission members 11 of the other flat wiring member 10, it becomes easier to distinguish between the two flat wiring members 10. Therefore, the flat wiring members 10 can be stacked accurately in the stacking process.

[0096] Furthermore, as in the above example, when two stacked flat wiring members 10 include at least one linear transmission member 11 of one flat wiring member 10 that is a different color from the linear transmission members 11 of the other flat wiring member 10, it becomes even easier to distinguish between the two flat wiring members 10. Therefore, the flat wiring members 10 can be stacked accurately in the stacking process.

[0097] Note that the specific examples of the colors exhibited by the linear transmission members 11 included in the flat wiring member 10 are not limited to the above examples.

[0098] <Regarding the arrangement of multiple linear transmission members in a flat wiring member> In the flat wiring member 10, a plurality of linear transmission members 11 having a common characteristic may be continuously arranged in parallel. FIG. 11 is a schematic plan view showing an example of a flat wiring member 10 in which a plurality of linear transmission members 11 having a common characteristic are continuously arranged in parallel. The flat wiring member 10 shown in FIG. 11 includes a plurality of types of linear transmission members 11 having different diameters. For example, the flat wiring member 10 may include a plurality of linear transmission members 11g having a large diameter and a plurality of linear transmission members 11h having a small diameter. In this case, in the flat wiring member 10, a plurality of linear transmission members 11g having a large diameter are continuously arranged in parallel, and a plurality of linear transmission members 11h having a small diameter are continuously arranged in parallel. Note that the flat wiring member 10 may include three or more types of linear transmission members 11 having different diameters.

[0099] 11, when a plurality of linear transmission members 11 having the same diameter are arranged in parallel in the flat wiring member 10, the plurality of linear transmission members 11 can be routed simultaneously, which makes it easier to manufacture the flat wiring member 10.

[0100] FIG. 12 is a schematic plan view showing another example of a flat wiring member 10 in which multiple linear transmission members 11 having a common characteristic are continuously arranged in parallel. The flat wiring member 10 shown in FIG. 12 includes multiple types of linear transmission members 11 that are different in color. In other words, the flat wiring member 10 includes multiple types of linear transmission members 11 whose outer surfaces have insulating coatings that are different in color. For example, the flat wiring member 10 may include multiple black linear transmission members 11i and multiple red linear transmission members 11j. In this case, as shown in FIG. 12, the flat wiring member 10 includes multiple linear transmission members 11i continuously arranged in parallel and multiple linear transmission members 11j continuously arranged in parallel. Note that the flat wiring member 10 may include linear transmission members 11 that are colors other than black and red. The flat wiring member 10 may also include three or more types of linear transmission members 11 that are different in color.

[0101] FIG. 13 is a schematic plan view showing another example of a flat wiring member 10 in which a plurality of linear transmission members 11 having common characteristics are continuously arranged in parallel. The flat wiring member 10 shown in FIG. 13 includes a plurality of types of linear transmission members 11 having different types of core wires. For example, the flat wiring member 10 may include a plurality of types of linear transmission members 11 having different core wire materials. For example, the flat wiring member 10 may include a plurality of linear transmission members 11k whose core wires are made of aluminum and a plurality of linear transmission members 11l whose core wires are made of copper. In this case, in the flat wiring member 10, a plurality of linear transmission members 11k are continuously arranged in parallel, and a plurality of linear transmission members 11l are continuously arranged in parallel. Note that the flat wiring member 10 may also include linear transmission members 11 whose core wires are made of a material other than aluminum and copper.

[0102] The flat wiring member 10 may include multiple types of linear transmission members 11 with different core wire shapes. For example, the flat wiring member 10 may include multiple types of linear transmission members 11k with stranded core wires and multiple linear transmission members 11l with solid core wires. The flat wiring member 10 may also include multiple types of linear transmission members 11 with different core wire compression rates. For example, the flat wiring member 10 may include multiple types of linear transmission members 11k with core wires that have a high core wire compression rate and multiple linear transmission members 11l with core wires that have a low core wire compression rate. The flat wiring member 10 may also include three or more types of linear transmission members 11 with core wires that have different types.

[0103] <Regarding the placement of linear transmission members at bends in flat wiring members> When the flat wiring member 10 has a bending portion 100 where a plurality of linear transmission members 11 are bent, the linear transmission member 11 with the smallest diameter may be located at the innermost side in the bending portion 100. The bending portion 100 may include all of the plurality of linear transmission members 11 included in the flat wiring member 10, or may include only some of the plurality of linear transmission members 11.

[0104] FIG. 14 is a schematic plan view showing an example of a bending portion 100. In the example of FIG. 14, the bending portion 100 of the flat wiring member 10 includes curved linear transmission members 11m, 11n, 11o, and 11p. The diameters of the linear transmission members 11m, 11n, 11o, and 11p increase in this order. In the bending portion 100, the linear transmission member 11m, which has the smallest diameter, is located on the innermost side. In the bending portion 100, the linear transmission members 11m, 11n, 11o, and 11p are arranged so that the larger the diameter, the more outer the linear transmission member. Therefore, the linear transmission member 11p, which has the largest diameter, is located on the outermost side.

[0105] In this way, in the bending portion 100, the linear transmission member 11m with the smallest diameter among the multiple linear transmission members 11m, 11n, 11o, and 11p is located at the innermost position. This allows for a larger bending radius for the linear transmission members 11n, 11o, and 11p with larger outer diameters than the linear transmission member 11m. By increasing the bending radius of the linear transmission members 11n, 11o, and 11p with larger diameters, the linear transmission members 11n, 11o, and 11p with larger diameters become easier to bend. This makes it easier to manufacture a flat wiring member 10 having a bending portion 100.

[0106] 14, when the multiple linear transmission members 11m, 11n, 11o, and 11p are arranged in the bending section 100 so that the larger the diameter of the linear transmission members 11, the larger the bending radius of the linear transmission members 11 can be made at the bending section 100. Therefore, the multiple linear transmission members 11m, 11n, 11o, and 11p become easier to bend.

[0107] Furthermore, when the plurality of linear transmission members 11m, 11n, 11o, and 11p are arranged in the bending portion 100 so that the larger the diameter, the more outwardly they are positioned, as shown in Fig. 14, it becomes easier to arrange the plurality of linear transmission members 11m, 11n, 11o, and 11p closely together in the bending portion 100. This makes it possible to reduce the space occupied by the bending portion 100. Therefore, it is possible to reduce the routing space for the flat wiring member 10.

[0108] The bent portion 100 of the flat wiring member 10 may include multiple linear transmission members 11 with the same diameter. For example, when the bent portion 100 includes multiple linear transmission members 11m, the multiple linear transmission members 11m are continuously arranged in parallel from the innermost to the outermost. When the bent portion 100 includes multiple linear transmission members 11p, the multiple linear transmission members 11p are continuously arranged in parallel from the outermost to the innermost.

[0109] Furthermore, the arrangement positions of the linear transmission members 11 other than the linear transmission member 11m with the smallest diameter among the multiple linear transmission members 11m, 11n, 11o, and 11p at the bending portion 100 are not limited to the example in Figure 14. For example, the linear transmission member 11o may be arranged at the outermost position of the bending portion 100. Furthermore, the linear transmission member 11o may be arranged next to the linear transmission member 11m.

[0110] Furthermore, when the laminated portion 2 of the wiring member 1 has a bending portion 200 that bends along the longitudinal direction of the linear transmission member 11, the flat wiring member 10 having the linear transmission member 11 with the smallest diameter may be positioned innermost in the bending portion 200.

[0111] FIG. 15 is a schematic cross-sectional view showing an example of the laminated portion 2 of the wiring member 1. In the example of FIG. 15, each of the flat wiring members 10A, 10B, and 10C includes a plurality of linear transmission members 11 of the same diameter. The diameters of the linear transmission members 11 differ among the flat wiring members 10A, 10B, and 10C. The flat wiring member 10A includes a linear transmission member 11q with the smallest diameter. The flat wiring member 10B includes a linear transmission member 11r with the second smallest diameter. The flat wiring member 10C includes a linear transmission member 11s with the largest diameter.

[0112] Fig. 16 is a schematic side view showing an example of a bending portion 200 included in the laminated portion 2 shown in Fig. 15. In the bending portion 200 shown in Fig. 16, a flat wiring member 10A including a linear transmission member 11q with a smallest diameter is located on the innermost side. In the bending portion 200, a flat wiring member 10B including a linear transmission member 11r with a second smallest diameter is located in the middle. In the bending portion 200, a flat wiring member 10C including a linear transmission member 11s with a largest diameter is located on the outermost side.

[0113] In this way, in the bending portion 200, the flat wiring member 10A including the linear transmission member 11q with the smallest diameter is located at the innermost position. This allows for a larger bending radius for the linear transmission members 11r and 11s, which have a larger outer diameter than the linear transmission member 11q. By increasing the bending radius of the linear transmission members 11r and 11s with a larger diameter, the linear transmission members 11r and 11s with a larger diameter become easier to bend. This makes it easier to fabricate a wiring member 1 having a bending portion 200.

[0114] 16, when the diameter of the linear transmission members 11 included in the flat wiring member 10 is larger, the flat wiring member 10 is positioned further outward at the bending portion 200, and the larger the diameter of the linear transmission members 11, the larger the bending radius of the linear transmission members 11 can be. Therefore, the multiple linear transmission members 11q, 11r, and 11s become easier to bend.

[0115] The bend 200 may include a plurality of flat wiring members 10 each having the same diameter of the linear transmission member 11. For example, if the bend 200 includes a plurality of flat wiring members 10A each having a linear transmission member 11q, the plurality of flat wiring members 10A are arranged continuously from the innermost to the outermost. If the bend 200 includes a plurality of flat wiring members 10C each having a linear transmission member 11s, the plurality of flat wiring members 10C are arranged continuously from the outermost to the innermost.

[0116] Furthermore, among the flat wiring members 10A, 10B, and 10C, the arrangement positions of the flat wiring members 10 other than the flat wiring member 10A having the linear transmission member 11q with the smallest diameter at the bending portion 200 are not limited to the example shown in Fig. 16. For example, the flat wiring member 10B may be provided at the outermost position of the bending portion 200.

[0117] As described above, the wiring member 1 has been described in detail, but the above description is merely an example in all respects, and this disclosure is not limited thereto. Furthermore, the various modifications described above can be combined and applied as long as they are not mutually inconsistent. It is understood that countless modifications not exemplified can be envisioned without departing from the scope of this disclosure. [Explanation of symbols]
