The wiring module of the embodiment will be explained below.

< vehicle for assembling wiring module >

Fig. 1 is a schematic perspective view showing a vehicle 10 in which a wiring module 20 is assembled. The vehicle 10 includes a vehicle body 12. The vehicle body 12 is a portion that forms the exterior of the vehicle 10. The vehicle body 12 may be a monocoque vehicle body or a vehicle body mounted on a ladder frame. Here, the vehicle body 12 includes a boarding/alighting door panel for boarding/alighting passengers, a rear door panel for taking out and putting in goods, and the like. The vehicle body 12 may be formed of metal or resin. The body 12 may also be constructed from a combination of metal and resin. A plate-like portion of the vehicle body 12 that covers the upper side of the vehicle compartment is a roof panel 13. The roof panel 13 may be partially or entirely curved in order to form the external shape of the vehicle body 12. The roof panel 13 may be formed of metal or resin. The roof panel 13 may also be composed of a combination of metal and resin. Here, the roof panel 13 is formed with an antenna hole 13h (see fig. 2).

The wiring module 20 is assembled to the vehicle 10. In the present embodiment, an example in which the wiring module 20 is assembled to the roof 14 including the roof panel 13 is described. The wiring module 20 may be incorporated in other parts of the vehicle 10, such as a loading/unloading door, a rear door, an instrument panel, and the like.

Fig. 2 is an exploded perspective view showing the wiring module 20. Fig. 3 is a perspective view showing the wiring module 20. Fig. 4 is a perspective view of the wiring module 20 as viewed from the side opposite to fig. 3. In fig. 2, the roof 14 is illustrated as a roof portion of a vehicle. The roof panel 13 and the interior member 16 are shown as the roof 14. The interior member 16 is a plate-like member formed of resin or the like. The interior member 16 may be partially or entirely curved to form a ceiling shape in the vehicle interior. The interior member 16 is attached to the lower side with respect to the roof panel 13. The interior member 16 is a portion exposed to the vehicle interior. The interior component 16 is sometimes referred to as a headliner (roof liner). In the present embodiment, the wiring module 20 is provided between the roof panel 13 and the interior member 16.

< Overall Structure of Wiring Module >

The wiring module 20 includes a sheet (sheet)30 and a linear transport member 40. The wiring module 20 is also provided with a device 50.

The sheet 30 is a sheet-like member to which the linear conveyance member 40 is fixed. Here, the device 50 is also fixed to the sheet 30. The sheet 30 is assembled to the roof 14 so as to spread flat with respect to the roof 14. For example, the sheet 30 may be arranged to extend to 8 or more areas with respect to the roof 14. For example, the sheet 30 may be arranged to extend over the entire upper portion of the headrests of a plurality of passenger seats in the vehicle interior. By arranging the sheet 30 to be spread with respect to the roof 14, the linear conveyance member 40 and the device 50 can be fixed to the roof 14 in an area as wide as possible.

The linear transport member 40 is an example of a transport member. The linear transmission member 40 is a linear member that transmits electricity, light, or the like. For example, the linear transmission member may be a general electric wire having a core wire and a coating layer around the core wire, or may be a bare wire, a shielded wire, a cable, an enameled wire, a nichrome wire, a coaxial wire, an optical fiber, or the like. The linear transmission member for transmitting power may be various signal lines or various power lines. The linear transport member may be a single wire or a composite of a plurality of wires (a stranded wire, a cable obtained by collecting a plurality of wires and covering the wires with a sheath, or the like). The conveying member is not limited to the linear conveying member 40, and may be a circuit or the like in which a conductive pattern is printed on the sheet 30.

The linear conveying member 40 is fixed to the sheet 30. The specific structure for fixing is not particularly limited as long as the linear conveyance member 40 is fixed to the sheet 30 so as to be arranged along a constant path.

For example, the linear conveying member 40 may be fixed to one main surface of the sheet 30. For example, the linear conveying member 40 may be welded (also referred to as fusion) to one main surface of the sheet 30. The welded portion thus formed is in a state in which a part of at least one of the linear conveying member 40 and the sheet 30 is melted and brought into close contact with each other. The welding of the linear conveying member 40 and the sheet 30 may be performed by ultrasonic welding or by heating welding. Further, at least one surface of the linear transport member 40 and the sheet 30 may be dissolved by a solvent, and the linear transport member 40 and the sheet 30 may be welded to each other. Further, for example, the linear transport member 40 may be fixed to the sheet 30 by an adhesive, a double-sided tape, or the like. Further, for example, the linear transport member 40 may be sewn to the sheet 30 by a suture or the like. For example, the linear transport member 40 may be fixed to one main surface of the sheet 30 by attaching an adhesive tape from one main surface side of the sheet 30 so as to straddle the linear transport member 40 in a state where the linear transport member 40 is disposed on one main surface of the sheet 30. The linear conveying member 40 need not be fixed to only one principal surface of the sheet 30. The linear transport member 40 may have both a portion fixed to one main surface of the sheet 30 and a portion fixed to the other main surface of the sheet 30. In this case, the linear transport member 40 may be attached so as to pass from one main surface to the other main surface at an intermediate portion or an edge portion of the sheet 30.

For example, the linear transport member 40 may be fixed to the sheet 30 by being sandwiched between 2 sheets. For example, in the case where the sheet 30 includes a plurality of layers, the linear conveyance member 40 may be sandwiched between sheets constituting each layer. When another sheet is superimposed on the sheet 30, the linear conveying member 40 may be interposed between the sheet 30 and the other sheet. In this case, the 2 sheets sandwiching the linear transport member 40 may be fixed by welding or may be fixed by an adhesive or a double-sided tape.

The linear transport member 40 is connected to the apparatus 50. The apparatus 50 transmits or receives an electric signal or an optical signal via the linear transfer member 40. Alternatively, the device 50 receives power supply or distributes power via the linear transport member 40. The connection of the linear transport member 40 to the apparatus 50 may also be made via a connector. The linear transport member 40 may be directly introduced into the apparatus 50 and may be directly connected to an electric component in the apparatus 50.

The device 50 is a device that is disposed on the roof 14 and serves as a connection destination of the linear transport member 40. As the device 50, for example, an electronic control unit, a lamp (particularly, an indoor lamp), a speaker, an indoor camera, a display, a projection device, an antenna for external communication, an indoor antenna, and the like can be conceived.

The device 50 is fixed relative to the sheet 30. The fixed position of the apparatus 50 relative to the sheet 30 is arbitrary. Preferably, the apparatus 50 is fixed relative to the sheet 30 in a position suitable for the function of the apparatus 50. For example, if the device 50 is assumed to be a map lamp, the device 50 is fixed to a portion of the sheet 30 disposed at a position diagonally above and in front of the front seat. Further, for example, if it is assumed that the device 50 is an indoor antenna, the device 50 is fixed to a portion of the sheet 30 disposed at a position above the front seat or the rear seat.

Here, the device 50 located at the center in the front-rear direction on the left-right direction side of the sheet 30 is referred to as an Electronic Control Unit (ECU) 50A (hereinafter, referred to as ECU 50A). The description will be made assuming that the plurality of devices arranged in the front-rear direction at the center in the left-right direction in the sheet 30 are an indoor lamp 50B (hereinafter, referred to as a lamp 50B), an indoor antenna 50C (hereinafter, referred to as an antenna 50C), an indoor lamp 50D (hereinafter, referred to as a lamp 50D), a display 50E, and an external communication antenna unit 50F (hereinafter, referred to as an antenna unit 50F) in this order from the front side. In the following description, when the ECU50A, the lamp 50B, the antenna 50C, the lamp 50D, the display 50E, and the antenna unit 50F need to be distinguished, the reference numerals 50A, 50B, 50C, 50D, 50E, and 50F are referred to, and when the distinction is not particularly required, the reference numerals may be collectively referred to as the devices 50.

Fig. 5 is a perspective view showing the ECU50A provided to the wiring module 20. The ECU50A is a device that controls each device 50 mounted on the roof 14 while communicating with another ECU provided in the vehicle 10. The ECU50A has a control circuit 51 a. Thus, the ECU50A controls each device 50 connected to the ECU 50A. The ECU50A has a circuit 51b that distributes power. Thereby, power is supplied to each device 50 connected to the ECU 50A.

The lamp 50B is a lamp for a front seat. The lamp 50D is a lamp for a rear seat. The display 50E is a display for a rear seat. The lamps 50B and 50D and the display 50E are devices required to be exposed to the vehicle interior. In this case, it is preferable that a hole is formed in the interior member 16. The lamps 50B and 50D and the display 50E can be exposed to the vehicle interior by fitting into the holes. The ECU50A and other devices that do not need to be exposed to the vehicle interior can be housed between the interior member 16 and the roof panel 13.

The antenna 50C is an antenna used for wireless communication between indoor devices (a smartphone, a mobile phone, a personal computer device, and the like) in a vehicle interior, for example. For example, the antenna 50C is an antenna for Wi-Fi (registered trademark) communication or an antenna for Bluetooth (registered trademark) communication. The antenna 50C may be an antenna for non-contact power supply that supplies power to indoor equipment in the vehicle interior in a non-contact manner. The frequency for the non-contact power supply is arbitrary. As the antenna 50C, for example, a printed board antenna in which an antenna is formed on a substrate by using a conductor foil or the like can be used. The printed board may be an FPC (Flexible printed circuit). If the antenna 50C is configured as a printed board antenna, the antenna 50C is mounted in a small occupied space with respect to the sheet 30. If the printed board antenna is configured as an FPC, the occupied space is further reduced. A sheet-like antenna such as an FPC antenna can easily follow a shape or the like deformed to correspond to a space where the antenna can be installed. In addition, the antenna 50C may be a rod antenna or the like. Here, 2 antennas 50C are provided, but the number of antennas 50C may be 1, or 3 or more.

The antenna unit 50F includes external communication antennas 53a and 53b (hereinafter, referred to as antennas 53a and 53b) for performing wireless communication with devices outside the vehicle. Here, the antenna unit 50F includes a base member 52, antennas 53a and 53b, and a cover 54. The base member 52 is formed in a flat shape, here, a square plate shape. The base member 52 is provided with antennas 53a and 53 b. The antennas 53a and 53b are antennas for communicating with devices outside the vehicle. The antennas 53a and 53b are, for example, antennas for performing communication with a wireless base station of a public communication line or a private communication line, antennas for vehicle-to-vehicle communication or road-to-vehicle communication, and antennas for receiving GPS signals. Here, the plurality of antennas 53a and 53b are attached to the base member 52. Thus, the plurality of antennas 53a and 53b are handled as a form of assembling 1. The antenna unit 50F may include only 1 antenna. The antenna unit 50F may further include 3 or more antennas. The cover 54 is made of resin or the like, and covers the upper side and the periphery of the antennas 53a and 53 b. The antenna hole 13h formed in the roof panel 13 is formed in a shape corresponding to the outer periphery of the cover 54. The cover 54 of the antenna unit 50F is partially fitted into the antenna hole 13h formed in the roof panel 13. Thus, even if the roof panel 13 is made of metal, the antennas 53a and 53b can be directed outward without being covered with metal.

< route of linear conveyance member in sheet >

The plurality of linear conveyance members 40 include linear conveyance members disposed along each of a path from the ECU50A toward the front, a path from the ECU50A toward the rear, and a plurality of paths from the ECU50A toward the respective devices 50 on the sheet 30 connected to the ECU 50A. In fig. 2 to 4, the linear transport member 40 in each path is simplified and only one is shown. In fig. 5, two linear transport members 40 are shown in each path. The number of the linear transport members 40 in each path is not particularly limited and is set as appropriate. In the path including the plurality of linear conveyance members 40, it is preferable that the plurality of linear conveyance members 40 be fixed to the sheet 30 in an aligned state.

The linear conveyance member 40A along the path directed forward from the ECU50A is held along a constant path by being fixed to the sheet 30 in the area of the sheet 30. The linear conveying member 40A extends outward from the front portion of the sheet 30. The linear transmission member 40A is disposed along, for example, an a-pillar in the vehicle, and is connected to other vehicle-side devices such as an ECU in the vehicle, a power supply, and the like. Further, for example, as shown in fig. 4, the linear transport member 40A may be connected to a wiring 80 disposed along an a-pillar or the like in the vehicle. The wiring 80 includes 1 or more linear conveyance members. In the wiring 80, a plurality of linear transport members may be bundled. The wiring 80 extends from other vehicle-side devices such as ECUs in the vehicle and the power supply to the roof portion via the pillars. The linear transmission member 40A may be connected to other vehicle-side devices such as an ECU in the vehicle, a power supply, and the like via the wiring 80. The connection form of the linear transport member 40A and the wiring 80 may be any connection form. In the example shown in fig. 4, the linear transport member 40A and the other wires 80 are connected by a connector. The linear conveying member 40A extends outward from the front portion of the sheet 30 on one side in the left-right direction of the vehicle. The linear conveying members 40A may extend outward from the front portion of the sheet 30 on both lateral sides in the lateral direction of the vehicle.

The linear conveying member 40B along the path toward the rear from the ECU50A is held along a constant path by being fixed to the sheet 30 in the area of the sheet 30. The linear conveying member 40B extends outward from the rear portion of the sheet 30. The linear transmission member 40B is disposed along, for example, a B pillar, a C pillar, or the like in the vehicle, and is connected to other vehicle-side devices such as an ECU in the vehicle, a power supply, or the like. For example, the linear transport member 40B may be connected to another wire arranged along a B pillar, a C pillar, or the like in the vehicle, similarly to the linear transport member 40A. The linear transmission member 40B may be connected to other wiring lines, and may be connected to other vehicle-side devices such as an ECU in the vehicle, a power supply, and the like.

The linear conveying members 40C, 40D, 40E, 40F along a plurality of paths from the ECU50A toward the plurality of devices 50 connected to the ECU50A are held along a constant path by being fixed to the sheet 30. The linear transport members 40C, 40D, 40E, and 40F are laid across a plurality of zones from a position where the ECU40A is mounted to a position where the connected devices 50 are provided. The paths of the linear transport members 40C, 40D, 40E, and 40F are set so as to pass through a specific area described later. Preferably, the paths of the linear transport members 40A, 40B, 40C, 40D, 40E, and 40F do not intersect with each other.

As shown in fig. 5, the linear transport member 40 in each path may include a signal line 42. The linear transmission member 40 in each path may include a power supply line 44. The linear transmission member 40 in each path may include both the signal line 42 and the power line 44, or may include only one of them. The number of signal lines 42 in each path may be one or plural, and is set as appropriate in accordance with the number of connection partners, a communication protocol, and the like. For example, in the case where the communication protocol is CAN (Control Area Network), typically, a pair of devices are connected to each other by a twisted pair of 2 coated wires twisted together. In addition, for example, in the case where the communication protocol is LIN (Local Interconnect Network), a pair of devices are usually connected to each other by 1 covering wire. The number of power supply lines 44 in each path may be one or plural, and is set as appropriate depending on the number of connection partners. In addition to this, the linear transport member 40 in each path may include a ground line. The grounding wire may be omitted by grounding the vehicle body.

In the example shown in fig. 5, the control circuit 51a in the ECU50A is connected to other ECUs in the vehicle via the signal line 42 in the linear transmission member 40A. Further, power is supplied to the circuit 51b for power distribution in the ECU50A via the power supply line 44 in the linear transmission member 40A. In the apparatus 50 connected to the ECU50A through the linear transmission member 40, the signal line 42 in the linear transmission member 40 is connected to the control circuit 51a in the ECU50A to control the apparatus 50. The power supply line 44 of the linear transmission member 40 is connected to the power distribution circuit 51b of the ECU50A to supply power to the device 50. Specifically, for example, the signal line 42 of the linear transmission member 40C is connected to the control circuit 51a of the ECU50A to control the lamp 50B. The power supply line 44 of the linear transmission member 40C is connected to the power distribution circuit 51B of the ECU50A to supply power to the lamp 50B.

The linear conveying member 40 may be connected to a device 50 that is not fixed to the sheet 30. For example, the antenna unit 50F may be fixed to the roof panel 13 without being fixed to the sheet 30. In this case, the linear conveying member 40F fixed to the sheet 30 may be connected to the antenna unit 50F. For example, when the wiring module 20 is assembled to the roof 14, the connector C of the wire-like transmission member 40F may be connected to the connector of the antenna unit 50F.

The linear transport member 40 may include a linear transport member having one end portion extending outward of the sheet 30 and the other end portion directly connected to the device 50 without passing through the ECU 50A. For example, one end of the linear conveying member 40G extends outward from the front of the sheet 30, and the other end is connected to the lamp 50B. The linear conveying member 40G is held along a constant path by being fixed to the sheet 30 in the area of the sheet 30. In addition, for example, a linear transport member may be provided, one end of which is connected to the antenna unit 50F and the other end of which extends outward from the sheet 30, such as the front or rear portion of the sheet 30, without passing through the ECU 50A.

The linear transport member 40 may include a linear transport member having one end portion and the other end portion extending outward from the sheet 30 and having an intermediate portion fixed to the sheet 30. Examples of such a linear transport member include a linear transport member extending in the front-rear direction of the vehicle.

< partition Structure in sheet >

At least 1 easily breakable portion 34 linearly extending along the main surface is formed in the sheet 30. The sheet 30 is divided into a plurality of zones a by the fracture facilitating portion 34. The plurality of regions a are connected in an initial state. In the case where repair is required in any one of the plurality of zones a, the zone a is easily divided from the other zones a by breaking the breakage facilitating portion 34 that divides the zone a, that is, by breaking the sheet 30 at the position of the breakage facilitating portion 34.

The breakage facilitating portion 34 extends from an edge of the sheet 30 or other breakage facilitating portion 34. The breakage facilitating portion 34 extends toward an edge of the sheet 30 or other breakage facilitating portion 34. The breakable portion 34 is not particularly limited as long as it facilitates the breaking of the sheet 30, and various configurations can be employed. For example, the breakage facilitating portion 34 may include a plurality of small holes formed intermittently. For example, the easy-to-break portion 34 may include a groove formed to be recessed in the thickness direction. The easy-to-break portion 34 may include both of a plurality of small holes and grooves. In fig. 2 to 5, the easy-to-break portion 34 is drawn by a two-dot chain line for distinction from other lines.

When the breakable part 34 includes a plurality of small holes, the direction in which the plurality of small holes are intermittently arranged is the extending direction of the breakable part 34. The plurality of intermittently formed small holes are also called an eye line or the like. The worker can easily break the sheet 30 by tearing the portions between the plurality of small holes in the sheet 30 so as to connect the plurality of small holes.

When the easy-to-break portion 34 includes a groove, the direction in which the groove extends along the main surface of the sheet 30 is the extending direction of the easy-to-break portion 34. The cross section of the groove is not particularly limited, but is preferably formed such that the width dimension gradually decreases from the opening in the main surface of the sheet 30 toward the bottom, for example, in a V-shape. The grooves may be formed only on one of the two main surfaces of the sheet 30, or may be formed on both of the main surfaces. By forming the groove, stress is easily concentrated. This makes it easy for the worker to break the sheet 30 along the groove.

When the easy-to-break portion 34 and the peripheral portion thereof in the sheet 30 are relatively hard, the sheet 30 is broken at the easy-to-break portion 34 by folding the sheet at the easy-to-break portion 34, for example. Thereby, the sheet 30 is broken at the position of the easy-to-break portion 34. In this case, the cracking facilitating portion 34 and the peripheral portion thereof in the sheet 30 can be understood to have a hardness capable of cracking.

In the case where the fracture facilitating portion 34 and the peripheral portion thereof in the sheet 30 are relatively soft to the extent that they cannot be fractured, the sheet 30 is fractured at the position of the fracture facilitating portion 34, for example, by being sequentially torn from one position in the fracture facilitating portion 34 along the extending direction. In this case, the portion of the sheet 30 where the easy-to-break portion 34 is formed is preferably tearable by hand so that the operator can tear the position of the easy-to-break portion 34 of the sheet 30 by hand.

In the present embodiment, 5 easy-to-break portions 34 are formed in the sheet 30. In the following description, when 5 easy-to-break portions 34 need to be distinguished, reference numerals 34A, 34B, 34C, 34D, and 34E are referred to, and when no special distinction is necessary, they may be collectively referred to as easy-to-break portions 34. The breakable sections 34A extend in the left-right direction and the front-back direction on the sheet 30 from a first position along the front-back direction in one side edge portion in the left-right direction of the sheet 30, and then extend to a second position along the front-back direction in the one side edge portion in the left-right direction. The easy-to-break portions 34B and 34C extend from the easy-to-break portion 34A toward the front of the sheet 30, and then extend laterally at the front portion of the sheet 30 to reach the other side edge portion of the sheet 30. The easy-to-break portions 34D and 34E extend rearward of the sheet 30 from the easy-to-break portion 34A, and then extend laterally at the rear portion of the sheet 30 to reach the other side edge portion of the sheet 30. The easy-to-break portion 34A has a U-shape. The easy-to-break portions 34B, 34C, 34D, and 34E are L-shaped. The sheet 30 is divided into 6 sections a by 5 fracture facilitating portions 34. In the following description, when 6 regions a need to be distinguished, reference numerals a1, a2, A3, a4, a5, and a6 are collectively referred to as regions a in some cases, when no special distinction is necessary.

Zone a1 is the zone to which ECU50A is secured. The fracture facilitating portion 34A divides the region a1 from the other regions a. The breakage facilitating portion 34A extends along the periphery of the ECU 50A. Although the end portions of the linear conveying members 40A, 40B, 40C, 40D, 40E, 40F are connected to the ECU50A, the linear conveying members 40A, 40B, 40C, 40D, 40E, 40F are not directly fixed with the sheet 30 in the zone a 1. Therefore, when the connection between the ends of the linear transport members 40A, 40B, 40C, 40D, 40E, and 40F and the ECU50A is released, the linear transport members 40A, 40B, 40C, 40D, 40E, and 40F are not fixed to the block a 1.

The region a2 is a region including the side edge portions and the front edge portion of the roof 14. The fracture facilitating portions 34A and 34B divide the region a2 and the other region a. The linear conveying members 40A, 40G are fixed to the sheet 30 in the region a 2. Device 50 is not secured in zone a 2.

The region a3 is a region located toward the front of the vehicle roof 14. The easy-to-break portions 34A, 34B, and 34C divide the region a3 and the other region a. The lamp 50B is fixed to the area a 3. The linear conveying members 40C, 40G are fixed to the sheet 30 in the region a 3.

Zone a4 is a zone located near the center of the vehicle roof 14. The easy-to-break portions 34A, 34C, and 34D divide the region a4 and the other region a. The antenna 50C and the lamp 50D are fixed to the area a 4. The linear conveying members 40D, 40E are fixed to the sheet 30 in the region a 4. The linear transport member 40E is connected to a display 50E fixed to the other area a 5.

The region a5 is a region located at the rear of the vehicle roof 14. The easy-to-break portions 34A, 34D, and 34E divide the region a5 and the other region a. A display 50E is fixed at the area a 5. The middle portion of the linear conveyance member 40F is fixed in the region a 5. The end of the linear transmission member 40F is connected to the antenna unit 50F fixed to the other zone a 6. Specifically, the through-holes 30b penetrating the front and back of the sheet 30 are formed in the region a 6. An end of the linear conveying member 40F fixed to the vehicle compartment side with respect to the sheet 30 is drawn out to the vehicle outer side surface with respect to the sheet 30 through the through hole 30 b. The connector C at the end of the linear conveying member 40F is connected to the antenna unit 50F outside the vehicle exterior surface with respect to the sheet 30.

Zone a6 is the zone located at the rear of the vehicle roof 14. The fracture facilitating portions 34A and 34E divide the region a6 and the other region a. At region a6, antenna element 50F is secured. The intermediate portion of the linear conveying member 40B is fixed to the area a 5. The linear conveying member 40B extends outward from the rear portion of the sheet 30. The intermediate portion of the linear transfer member 40F connected to the antenna unit 50F is not fixed to the area a 6.

A plurality of fixing portions for the mounting object are provided in each of the areas a2, A3, a4, a5, and a 6. Here, a plurality of mounting holes 32h are formed at each of the regions a2, A3, a4, a5, a 6. For example, by passing bolts through the mounting holes 32h and fixing the bolts to the roof panel 13, the respective zones a2, A3, a4, a5, a6 are fixed to the roof panel 13 at the positions of the mounting holes 32 h. For example, by inserting a clip into the mounting hole 32h and inserting and locking the clip into a clip hole formed in the roof panel 13, the sections a2, A3, a4, a5, and a6 are fixed to the roof panel 13 at the position of the mounting hole 32 h. A fixing member such as a clamp may be provided at the fixing portion.

The sheet 30 includes a first region and a second region that are divided by at least 1 fracture facilitating portion 34. The plurality of linear delivery members 40 includes a first linear delivery member and a second linear delivery member. The first linear conveying member is a linear conveying member held in the first zone in a state where the sheet 30 is divided into the first zone and the second zone. The first linear conveying member is a linear conveying member in which most of the intermediate portion fixed to the sheet 30 is fixed to the first area in a state before the sheet 30 is divided into the first area and the second area. The second linear conveying member is a linear conveying member held in the second area in a state where the sheet 30 is divided into the first area and the second area. The second linear conveying member is a linear conveying member in which most of the intermediate portion fixed to the sheet 30 is fixed to the second area in a state before the sheet is divided into the first area and the second area. A fracture facilitating portion 34 that demarcates the first zone and a fracture facilitating portion 34 that demarcates the second zone extend from the apparatus 50. In this embodiment, any 2 of the regions a2, A3, a4, a5, and a6 can be the first region and the second region.

The most part of the middle portion of the linear conveying member 40 is fixed to the sheet 30 means that, for example, when the linear conveying member 40 is continuously fixed to the sheet 30, a portion of 7 or more is fixed to the sheet 30 with respect to the total extension of the fixed portion. For example, the most part of the middle portion of the linear transport member 40 is fixed to the sheet 30, and when the linear transport member 40 is intermittently fixed to the sheet 30, a portion of 7 or more is fixed to the sheet 30 with respect to the total number of the fixed portions.

In a state before the sheet 30 is divided into the first zone and the second zone, it is preferable that the intermediate portion in the first linear conveying member is fixed only to the first zone. In this case, when the first zone is broken at the position of the breakage facilitating portion 34, the intermediate portion of the linear transport member 40 may not be detached from the first zone. It is understood that the linear transport member 40, which is preferably fixed to the plurality of zones a without an intermediate portion, is not present. In the present embodiment, the regions a4 and a5 can be the first regions described above. More specifically, the intermediate portions of the linear conveyance members 40D, 40E fixed to the section a4 are fixed only to the section a4 in a state before the section a4 is divided from the other section a. The intermediate portion of the linear transport member 40F fixed to the zone a5 is fixed only to the zone a5 in a state before the zone a5 is divided from the other zone a.

The first linear transfer member has a first signal line connecting the device and the first device. The second linear transmission member has a second signal line connecting the device and the second device. In the present embodiment, the linear transport members 40C, 40D, 40E, and 40F may be the first and second linear transport members. That is, the linear transmission members 40C, 40D, 40E, 40F, which connect the ECU50A and the other devices 50, respectively, include the signal line 42.

The first linear transport member has a first power supply line connecting the device and the first device. The second linear transport member has a second power supply line connecting the device and the second device. In the present embodiment, the linear transport members 40C, 40D, 40E, and 40F may be the first and second linear transport members. That is, the linear transmission members 40C, 40D, 40E, 40F, which connect the ECU50A and the other devices 50, respectively, include the power supply line 44.

The wiring module 20 includes a plurality of identical functional devices that implement the same function. The breaking facilitating portion 34 divides the sheet 30 such that a plurality of identical functional devices are arranged in the same one of the first and second regions. In the present embodiment, the plurality of antennas 50C are the same functional device, and are arranged in the same area a4 by the breakable sections 34A, 34C, and 34D. In this example, the plurality of displays 50E are the same functional device, and are arranged in the same area a5 by the easy-to-break portions 34A, 34D, and 34E.

The wiring module 20 further includes a first functional device and a second functional device that realize different functions. The breaking facilitating portion 34 divides the sheet so that both the first functional device and the second functional device are disposed in the same one of the first area and the second area. In the present embodiment, the antenna 50C and the lamp 50D realize different functions, and are disposed in the same area a4 by the easy-to-break portions 34A, 34C, and 34D.

In the case where the ECU50A is connected to the linear transmission members 40 facing a plurality of zones a, the linear transmission members 40 facing mutually different zones a are preferably connected to the ECU50A via different connectors C. In the present embodiment, the linear transmission members 40A, 40B, 40C, 40D, 40E, and 40F are connected to the ECU50A via different connectors C, respectively. Thus, when the specific section a is divided, the connection between the linear transmission member 40 corresponding to the divided section a and the ECU50A can be easily released by detaching the connector C corresponding to the divided section a from the ECU 50A.

< fixing Structure of apparatus to sheet >

An example of a fixing structure of the apparatus 50 to the sheet 30 will be described. The device 50 may be secured directly to the sheet 30. The device 50 may also be fixed to the sheet 30 via a device holder. In fig. 5, an example is shown in which the apparatus 50 (the ECU50A in the example shown in fig. 5) is directly fixed to the sheet 30. The device 50 is fixed directly to one main face of the sheet 30. Here, the fact that the device 50 is directly fixed to the sheet 30 means that the device 50 is fixed without using another fixing holder or the like.

For example, the device 50 may be welded (also referred to as fused) to one major surface of the sheet 30. The welded portion thus formed is in a state in which at least one of the device 50 and the sheet 30 is partially melted and closely attached to each other. The welding of the device 50 to the sheet 30 may be performed by ultrasonic welding or by heating. Alternatively, at least one of the surfaces of the device 50 and the sheet 30 may be dissolved by a solvent, whereby the device 50 and the sheet 30 may be welded to each other. Further, for example, the device 50 may be fixed to the sheet 30 by an adhesive, a double-sided tape, or the like. In addition, for example, the device 50 may also be sewn with respect to the sheet 30 by a stitch or the like. For example, a sewing tab may be formed on the exterior of the device 50. Preferably, the tab has a hole formed therein. By means of which the device 50 is sewn to the sheet 30. Further, the device 50 may be fixed to the sheet 30 by sandwiching the sheet 30 between the device 50 and the fixing plate. For example, the device 50 is disposed on one main surface side of the sheet 30, and a plate-like fixing plate is disposed on the other main surface side of the sheet 30. In this state, the screw penetrating the sheet 30 fastens the device 50 and the fixing plate in the approaching direction. Thereby, the sheet 30 is sandwiched between the device 50 and the fixing plate.

The device 50 may be fixed to either one of the one main surface and the other main surface of the sheet 30. In fig. 5, the device 50 is fixed to a lower surface (vehicle compartment side) of the sheet 30. For example, the device 50 is formed in a rectangular parallelepiped shape. The device 50 is directly fixed to the lower surface of the sheet 30 in a state where one principal surface thereof is in contact with the lower surface of the sheet 30.

Here, a fixing piece 55 for fixing to the roof 14 is provided to protrude from the equipment 50. The fixing piece 55 is formed with a screw insertion hole for screw fixation. An opening 31h is formed in the sheet 30 at a position corresponding to the fixing piece 55. Therefore, the fixing piece 55 can be overlapped on the lower surface side of the roof panel 13 in a state where the wiring module 20 is disposed between the roof panel 13 and the interior member 16. This allows the fixing piece 55 to be easily screwed to the roof panel 13. For example, the fixing pieces 55 can be screwed to reinforcing bars (also referred to as stay bars, beams, or the like) in the roof panel 13.

In the present embodiment, the lamps 50B and 50D, the antenna 50C, the display 50E, and the antenna unit 50F, which are examples of the device 50, are also directly fixed to the sheet 30 in the same manner as described above. The device 50 directly fixed to the sheet 30 may be referred to as a direct fixing device.

Fig. 6 is a perspective view illustrating a state in which the apparatus 150 is fixed to the sheet 30 via the apparatus holder 60. Fig. 7 is a side view showing the device 150 and the device holder 60.

The device holder 60 is configured to be able to hold the device 150 in a state of being fixed to the sheet 30. Here, the device holder 60 includes a holder main body 62 and a fixing piece 64.

The holder main body 62 is formed of resin or the like into a rectangular parallelepiped box shape having one end open. The holder main body portion 62 is directly fixed to one main surface of the sheet 30, as in the above-described direct fixing device. A space capable of accommodating a part or all of the devices 150 is formed inside the holder main body portion 62. Here, the device 150 is formed in a rectangular parallelepiped shape. A rectangular parallelepiped space corresponding to the outer shape of the device 150 is formed inside the holder main body portion 62.

A hooking piece 63 capable of hooking to the device 150 is formed in the holder main body portion 62. Here, an elongated groove-like recess 151 is formed in the outer periphery of the device 150. A hook 63 is formed in a part of the opening of the holder main body 62. Both side portions of the hooking piece 63 are separated from the other portions of the holder main body portion 62. Therefore, the catching piece 63 can be elastically deformed in the inward and outward directions of the holder main body portion 62 with its base end portion as a supporting portion. A projection 62a projecting toward the inside of the holder main body 62 is formed at the front end of the engaging piece 63. When the device 150 is inserted into the holder main body portion 62, the convex portion 62a comes into contact with the outer surface of the device 150, and the engaging piece 63 is elastically deformed outward. When the device 150 is inserted into the holder main body 62 to the rear side thereof until the projection 62a reaches the recess 151, the engagement piece 63 elastically returns to its original shape, and the projection 62a is fitted into the recess 151. Thereby, the device 150 is held in the retainer main body 62 in a slip-off prevention state. It is not essential that the holder main body portion 62 have a hooking structure by the hooking piece 63. For example, the device 150 may also be held within the holder main body portion 62 by a holding force based on connector connection. The device 150 may also be fixed relative to the holder main body portion 62 by screw fastening or the like.

The holder main body portion 62 is provided with a holder side connector 66. The holder-side connector 66 is provided on the back side of the holder main body 62. The holder-side connector 66 is exposed to the outside and the inside of the holder main body 62. The linear transport member 40 is introduced into the holder-side connector 66 from an outward portion of the holder-side connector 66. The linear transmission member 40 is connected to the terminals in the holder-side connector 66. The terminals in the holder-side connector 66 are exposed in the holder main body portion 62.

A device-side connector 152 that can be connected to the holder-side connector 66 is provided at a portion of the device 150 that is inserted into the back side of the holder main body portion 62. As described above, when the device 150 is inserted into the holder main body 62, the device-side connector 152 and the holder-side connector 66 are connected by the connectors.

The fixing piece 64 is provided to protrude from the holder main body 62. The fixing piece 64 has the same structure as the fixing piece 55 provided in the direct fixing device. An opening 31h is formed in the sheet 30 at a position corresponding to the fixing piece 64. Therefore, the fixing piece 64 can be overlapped on the lower surface side of the roof panel 13 in a state where the wiring module 20 is disposed between the roof panel 13 and the interior member 16. This allows the fixing piece 64 to be easily screwed to the roof panel 13. In the structure using the retainer, the indirect fixing device itself may be fixed to the roof panel 13 or the like.

The device 150 fixed to the sheet 30 via the device holder 60 may also be referred to as an indirect fixing device. If an indirect fixing device such as the device 150 is used for the wiring module 20, the device 150 can be easily detached from the wiring module 20, and the repairability can be improved.

In the wiring module 20, a structure in which the device 50 is directly attached to the sheet 30 and a structure in which the device 150 is attached to the sheet 30 via the device holder 60 may be mixed. For example, since the antenna 50C is formed in a sheet shape, it may be directly fixed to the sheet 30 without the device holder 60.

The device 50 and the device holder 60 are preferably finally fixed to the roof panel 13, the interior member 16, or the like. The device 50 and the device holder 60 may be fixed to the sheet 30 with such strength that a predetermined position can be maintained with respect to the sheet 30 before the device is fixed to the roof panel 13 or the like.

< method for repairing Wiring Module >

A method of repairing the wiring module 20 will be described with reference to fig. 8 and 9. Fig. 8 is an explanatory diagram showing a case of repairing the wiring module 20. Fig. 9 is a perspective view showing the repaired wiring module 20R. As shown in fig. 8 and 9, the repair area a5 will be described as an example.

First, the easily breakable portions 34A, 34C, and 34D of the dividing region a5 are broken. The easy-to-break portions 34C and 34D define a region a5 over the entire length. Such easily breakable portion 34 is broken over the entire length. The fracture facilitating portion 34A divides the region a5 only along a part of the extending direction. The easily breakable part 34 need not be broken over the entire length, but may be broken only in a part of the dividing region a 5.

Next, the zone a5 in the sheet 30 and the linear conveyance member 40F fixed to the zone a5 are detached from the wiring module 20 and the vehicle (roof panel 13). Regarding the removal of the section a5, here, since the portion of the sheet 30 constituting the section a5 is fixed to the vehicle by bolts or the like at the position of the mounting hole 32h, the fixation is released. In addition, in regard to the detachment of the linear transmission member 40F, since the end portion of the linear transmission member 40F is connected to the ECU50A and the antenna unit 50F which are not fixed to the area a5, the connected state is released. For example, when the connector C provided at the end of the linear transmission member 40F is detached from the ECU50A, the connection state between the linear transmission member 40F and the ECU50A is released. Similarly, when the connector C provided at the end of the wire-shaped transmission member 40F is detached from the antenna unit 50F, the connection state between the wire-shaped transmission member 40F and the antenna unit 50F is released. The intermediate portion of the linear conveying member 40F is not directly fixed to the sheet 30 in the area a other than the area a 5. Therefore, by simply releasing the end portion and the device from the connected state in the linear transport member 40F, the linear transport member 40F can be removed together when the area a5 is removed from the wiring module 20 and the vehicle.

Here, the display 50E fixed to the area a5 is also detached from the wiring module 20 and the vehicle. With respect to the removal of the display 50E fixed to the area a5, since the end of the linear conveyance member 40E not fixed to the area a5 is connected to the display 50E fixed to the area a5, the connected state is released. For example, when the connector C provided at the end of the linear transport member 40E is detached from the display 50E, the connection state between the linear transport member 40 and the display 50E is released. Further, the fixing of the display 50E and the roof panel 13 by the fixing piece 55 is released. The intermediate portion of the linear conveying member 40E is not directly fixed to the sheet 30 in the area a 5. Thus, the following is suppressed: by merely releasing the connection state of the end portions in the linear transport member 40E, the linear transport member 40E is detached together when the area a5 is detached from the wiring module 20.

Next, the linear transport member 40F, the display 50E, and the like fixed to the area a5 are repaired. The sheet 30 portion, the linear conveying member 40F, and the display 50E in the area a5 are reused if they can be reused, and are replaced if they cannot be reused. Regarding the portion of the sheet 30, the linear conveying member 40F, and the display 50E in the area a5, the component after completion of repair (including refurbishment) is referred to as a repair RP, regardless of recycling or replacement. In the repaired product RP, the path of the intermediate portion of the linear transport member 40F may be the same as that in the state before the repair or may be different from that in the state before the repair. In the repaired product RP, the fixing form of the linear transport member 40F and the sheet 30 may be the same as that in the state before the repair or may be different from that in the state before the repair. In the repair product RP, the fixing form of the display 50E and the sheet 30 may be the same as that in the state before the repair or may be different.

Subsequently, the repair product RP in the area a5 and the linear conveying member 40F is mounted on the wiring module 20 and the vehicle. With respect to the mounting of zone a5, mounting holes 32h are used and the portion of sheet material 30 in zone a5 is secured to the vehicle. Further, in the mounting of the linear transport member 40F, the passage area a5 is disposed at a predetermined position of the vehicle, and the linear transport member 40F fixed to the area a5 is disposed along a predetermined path. In this state, the end of the linear transmission member 40F is located in the vicinity of the ECU50A and the antenna unit 50F of the unfixed area a 5. Then, the end of the linear transmission member 40F is connected to the ECU50A and the antenna unit 50F. For example, the ECU50A and the antenna unit 50F are connected to the connector C provided at the end of the linear transmission member 40F, and the ECU50A and the antenna unit 50F are connected to the linear transmission member 40F.

In addition, here, the repair product RP also includes a display 50E fixed to the area a 5. Therefore, the mounting of the repair product RP to the wiring module 20 and the vehicle includes the mounting of the display 50E. The display 50E fixed to the area a5 is mounted so that the area a5 is disposed at a predetermined position and the display 50E is also disposed at a predetermined position. In a state where the display 50E is disposed at a predetermined position, the fixing piece 55 is located in the vicinity of a predetermined fixing position. Thereafter, the display 50E is fixed to the vehicle by the fixing piece 55. In addition, the end of the linear transport member 40E not fixed to the area a5 is connected to the display 50E fixed to the area a 5. For example, in a state where the display 50E is arranged at a predetermined position, the connector C provided at the end of the linear transport member 40E is positioned in the vicinity of the display 50E. Then, the linear transport member 40E and the display 50E are connected by the connector C provided at the end of the linear transport member 40E and the display 50E.

In the wiring module 20, the repair of the portion related to the area a5 is completed. In the case where repair is required for the other area a, repair can be performed in the same manner as in the case of the area a 5. It should be noted that a region spanning multiple adjacent zones a may also be repaired at one time. In this case, the easily breakable portion 34 that divides the adjacent region may not be broken.

In the wiring module 20R after the repair is completed, a part of the breakage facilitating portion 34 disappears compared to the wiring module 20 before the repair. The repair product RP is present in the area a independently of the other areas a.

< effects of the embodiment, etc. >

According to the wiring module 20 thus configured, the sheet 30 is easily divided in units of the areas a by being broken using the breaking easy portions 34. When the sheet 30 is divided into the unit of the block, the predetermined linear conveying member 40 is held in each block, and therefore, the sheet can be replaced in the unit of the block a. This can improve the repairability of the wiring module 20 in which the linear conveying member 40 is fixed to the sheet 30. When the wiring module 20 is repaired, the part of the region a is repaired, so that the wiring module 20 is not completely replaced, and the cost for replacement can be reduced.

In a state before the section a4 is divided from the other section a, the intermediate portion of the linear conveyance members 40D, 40E is fixed only to the section a 4. Therefore, when the section a4 is divided, the intermediate portion of the linear transport members 40D and 40E does not need to be detached from the other section a. Thus, the detachment of the area a4 becomes easy. In addition, damage is not easily generated to the other portion in the region a in the sheet 30. The same is true with respect to zone a 5.

The fracture facilitating portions 34B, 34C, 34D, and 34E of the divided regions a2, A3, a4, a5, and a6 extend from the position where the ECU50A is disposed (here, the fracture facilitating portion 34A of the region a1 where the ECU50A is disposed). Therefore, the partitioning can be performed based on the ECU 50A. This facilitates the path design of the linear conveyance member 40 corresponding to the plurality of zones a.

The linear transmission members 40C, 40D, 40E, 40F have signal lines 42 connecting the ECU50A and the devices 50 connected thereto. Thus, the signal line 42 is divided into the unit of zones with the ECU50A as a reference. The linear transmission members 40C, 40D, 40E, 40F have power lines 44 connecting the ECU50A and the devices 50 connected thereto. Thus, the power supply line 44 is divided into the zone units with the ECU50A as a reference. The linear transmission members 40C, 40D, 40E, 40F are laid across a plurality of zones from the position of the ECU50A to the position of the equipment 50. Thereby, the repairability of the wiring module 20 connecting the ECU40A and the apparatus 50 provided on the sheet 30 via the linear conveying members 40C, 40D, 40E, 40F can be improved.

The easy-to-break portions 34A, 34C, and 34D divide the sheet 30 so that a plurality of antennas 50C that achieve the same function are disposed in the same area a 4. The easy-to-break portions 34A, 34D, and 34E divide the sheet 30 so that a plurality of displays 50E having the same function are disposed in the same area a 5. Thus, the same functional device can be arranged in the same area a.

Since the easy-to-break portions 34A, 34C, and 34D divide the sheet 30 so that the antenna 50C and the lamp 50D that realize different functions are disposed in the same area a4, a relatively wide range can be set to 1 area to some extent.

A plurality of mounting holes 32h for fixing to the mounting object are provided in each area a. Thus, a plurality of locations can be fixed to the vehicle in 1 zone a. Thus, the replaced region a is stable.

The roof 14 is a portion that extends relatively largely in the vehicle 10. By being able to improve the repairability in the wiring module 20 for the roof 14 that is relatively large in size, it is possible to eliminate the need to replace the wiring module 20 entirely, and it is possible to reduce the cost involved in the replacement.

[ modified examples ]

In the above embodiment, the breaking facilitating portion 34 is provided with reference to the ECU50A having the power distribution function and the control function, but this is not an essential configuration. Instead of the ECU50A, a device (e.g., a junction box) having only a power distribution function may be used as the reference device. Instead of the ECU50A, a communication relay device (e.g., a switching hub) may be used as a reference device. Further, a power supply communication relay device having a power supply distribution function and a communication relay function may be used as a reference device instead of the ECU 50A. In addition, there may be a case where the ECU50A has a control function and does not have a power distribution function.

The sheet 30 may have 1 or more functions other than fixing the linear conveying member 40 and the device 50. Examples of the other functions include a heat insulating function, a sound insulating function, and a radio wave shielding function. When the sheet has a plurality of other functions, 1 layer may have a plurality of functions, or different layers may be provided for each function. The layers may simply overlap each other. The multiple layers may also be secured by double-sided tape, adhesive, welding, or the like.

The heat insulating layer is a layer that makes it difficult for heat to be transferred between the one main surface side and the other main surface side of the sheet 30. The thermal insulation layer may be a layer that reflects thermal radiant energy. The heat insulating layer may be a layer having a lower thermal conductivity than other layers. Specifically, as the heat insulating layer, a sheet having fine gaps such as a nonwoven sheet or a foam sheet can be used. As the heat insulating layer, a heat insulating coating or a heat shielding coating may be used.

The sound insulation layer is a layer that makes it difficult for sound to be transmitted between the one main surface side and the other main surface side of the sheet 30. The soundproof layer may reflect sound or absorb energy of sound as heat energy. Specifically, as the sound insulating layer, a sheet having fine gaps such as a nonwoven sheet or a foam sheet can be used. As the sound insulation layer, sound absorbing paint may be used.

The radio wave shielding layer is a layer that makes it difficult for radio waves to be transmitted between one main surface side and the other main surface side of the sheet 30. The electric wave shielding layer may have electric wave shielding properties with respect to all frequencies. The radio wave shielding layer may have a selective radio wave shielding property with respect to a part of the frequency band. In this case, the radio wave of a part of the frequency band may be at least one of reflected and absorbed by the radio wave shielding layer. The electric wave shielding layer may be a layer formed of metal such as aluminum or iron. As the radio wave shielding layer having Selective radio wave shielding properties, a known Frequency Selective membrane (FSS) may be used. In the frequency selective film, a unit body (element) is formed of a metal foil or the like on a base film made of a resin or the like. The frequency selective membrane selectively shields radio waves of 1 or more frequency bands and passes radio waves of other frequency bands according to the frequency characteristics of the unit bodies (elements). The radio wave shielding layer having selective radio wave shielding properties may be formed by directly printing a conductive paste or the like on the heat insulating layer or the sound insulating layer. In this case, the heat insulating layer or the sound insulating layer is a layer that also serves as the radio wave shielding layer.

When the frequency band of the radio wave radiated from the antenna 50C is included in the frequency band shielded by the frequency selective film, the radio wave is shielded by the frequency selective film. When the frequency band of any of the radio waves emitted from the antennas 53a and 53b is included in the frequency band shielded by the frequency selective film, any of the radio waves emitted from the antennas 53a and 53b is shielded by the frequency selective film. When the frequency band of any of the radio waves radiated from the antennas 53a and 53b is out of the range of the frequency band shielded by the frequency selective film, the radio wave for external communication passes through the frequency selective film.

In the embodiment, the antenna unit 50F is formed in a thin box shape, but this is not a necessary structure. The antenna unit 50F may also be formed in a fin (fin) shape or a rod shape. In this case, the antenna unit formed in a fin-like or rod-like shape may be inserted into a hole formed in the roof panel and protrude outward from the roof panel. The antennas 53a and 53b are preferably assembled to the fin-shaped or rod-shaped antenna unit so as to be positioned outside the roof panel.

The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not contradictory to each other.

The present disclosure includes the following wiring module.

(1) A wiring module; the sheet includes a first region and a second region defined by the at least 1 breakable portion, and the plurality of linear conveyance members include a first linear conveyance member held in the first region and a second linear conveyance member held in the second region in a state where the sheet is divided into the first region and the second region. The sheet is easily divided into zone units by being broken using the breaking easily portion. Since the first linear conveyance member is mainly fixed to the first zone and the second linear conveyance member is mainly fixed to the second zone, replacement is easy in a zone unit. In a wiring module in which a linear conveying member is fixed to a sheet, repairability can be improved.

(2) In the wiring module of (1), the intermediate portion of the first linear transport member may be fixed only to the first region in a state before the sheet is divided into the first region and the second region. Thus, when the first zone is divided from the other zones, the intermediate portion of the first linear conveyance member does not need to be detached from the other zones. Thus, the detachment of the first region becomes easy. In addition, damage is not easily generated to portions in other regions in the sheet.

(3) The wiring module according to (1) or (2) may further include a device disposed on the sheet, and the easy-to-break portion defining the first region and the easy-to-break portion defining the second region may extend from a position where the device is disposed. This makes it possible to divide the device into regions. The path design of the linear transport member corresponding to the plurality of zones becomes easy.

(4) In the wiring module according to (3), the first linear transport member may have a first signal line connecting the device and a first device, and the second linear transport member may have a second signal line connecting the device and a second device. Thus, the signal lines are divided into the unit of sections with the device as a reference.

(5) In the wiring module according to (3) or (4), the first linear transport member may have a first power supply line connecting the device and a first device, and the second linear transport member may have a second power supply line connecting the device and a second device. Thus, the power supply line is divided into the unit of blocks with the device as a reference.

(6) In any one of the wiring modules (1) to (5), the breaking facilitating portion may be provided with a plurality of identical functional devices that realize identical functions, and the sheet may be divided so that the plurality of identical functional devices are arranged in the same one of the first area and the second area. Thus, the same functional device is disposed in the same area.

(7) In any one of the wiring modules (1) to (6), the wiring module may further include a first functional device and a second functional device that realize different functions from each other, and the easy-to-break portion may divide the sheet so that both the first functional device and the second functional device are disposed in the same one of the first zone and the second zone. This makes it possible to set a range which is wide to some extent to 1 block.

(8) In any one of the wiring modules (1) to (7), a plurality of fixing portions to be attached may be provided in each of the first region and the second region. Thus, a plurality of portions can be fixed to the vehicle in 1 zone, and therefore the zone after replacement is stable.

(9) In any of the wiring modules (1) to (8), the sheet may be a sheet assembled to a roof. This makes it possible to improve the repairability of the wiring module for the roof, which is relatively large, to eliminate the need to replace the wiring module entirely, thereby reducing the cost involved in the replacement.

(10) Further, a method for repairing a wiring module according to the present disclosure is a method for repairing any one of (1) to (9), including: a step of breaking the easily breakable portion that divides the first region; a step of detaching the first region and the first linear transport member from the wiring module and the vehicle; and a step of mounting the first block and the repaired product of the first linear transport member on the wiring module and the vehicle. This eliminates the need to completely replace the wiring module, and reduces the cost involved in replacement.
