DETAILED DESCRIPTION OF THE INVENTION

[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 comprising: a first connector and a second connector; a first linear transmission member connected to the first connector; a second linear transmission member connected to the second connector; and a sheet to which the first linear transmission member and the second linear transmission member are fixed, wherein the first linear transmission member and the second linear transmission member extend parallel to each other on the sheet so that the end of the first linear transmission member connected to the first connector and the end of the second linear transmission member connected to the second connector are directed toward a first end of the sheet, and a tear line for tearing the sheet is formed on the sheet, the tear line extending between the first linear transmission member and the second linear transmission member, and one end of the tear line reaching the edge of the first end. The tear line extends between the first linear transmission member and the second linear transmission member, and one end of the tear line reaches the edge of the first end, so that the wiring member can accommodate multiple product numbers by tearing a portion of the sheet from the first end using the tear line as needed.

[0012] (2) In the wiring member of (1), the other end of the tear line may be located in an intermediate region between the first end and the second end of the sheet, thereby preventing the sheet from completely separating into two pieces.

[0013] (3) The wiring member of (2) may further include a third linear transmission member having one end connected to the first connector and the other end connected to the second connector, wherein an intermediate portion of the third linear transmission member is located farther from the first end than the tear line, and the third linear transmission member extends from the intermediate portion of the third linear transmission member toward the one end on one side of the tear line in the sheet, and extends from the intermediate portion of the third linear transmission member toward the other end on the other side of the tear line in the sheet. This allows for easy support for multiple product numbers with a simple configuration, even when there is a third linear transmission member connecting the first connector and the second connector.

[0014] (4) In any one of the wiring members (1) to (3), the sheet may have a through hole formed at the middle of the tear line. This allows the tearing of the sheet by the tear line to be interrupted at the position of the through hole. Furthermore, if the tear length of the tear line varies depending on the product number, the through hole can be used as a guide for the tear length of the tear line.

[0015] (5) In any one of the wiring members (1) to (4), the intersection of the first linear transmission member and the second linear transmission member on the sheet may be located at a position that avoids the tear line, thereby preventing the intersection from interfering with the tear line when the sheet is torn.

[0016] (6) In any one of the wiring members (1) to (5), the sheet may be torn along the tear line to separate it into a first sheet portion to which the first linear transmission member is fixed and a second sheet portion to which the second linear transmission member is fixed, and the first sheet portion may be folded back, thereby obtaining a wiring member corresponding to a different product number from that obtained when the wiring member is not torn along the tear line.

[0017] (7) In the wiring member of (6), the overlapping sheets may be fused and fixed together at the folded-back portion of the first sheet portion, thereby allowing the wiring member to be easily maintained in the folded-back shape.

[0018] (8) In the wiring member of (6) or (7), the first sheet portion may be folded over the second sheet portion, and the overlapping first and second sheet portions may be fixed together. This makes it easy to fix the folded portion even when there is little free margin in the sheet.

[0019] (9) In the wiring member of any one of (6) to (8), the first linear transmission member may be fixed to the sheet at multiple locations spaced apart along the extension direction, and the fixed locations of the first linear transmission member and the sheet may be located at the folded-back portion of the first sheet portion. This makes it difficult for the first linear transmission member to separate from the first sheet portion when folded back together with the first sheet portion.

[0020] [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 disclosure 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.

[0021] [Embodiment 1] The following describes the wiring member according to embodiment 1. Fig. 1 is a schematic plan view showing a wiring member 10 according to embodiment 1. Fig. 2 is a partially enlarged view of Fig. 1.

[0022] The wiring member 10 electrically (or optically) connects various components in a vehicle or the like. The wiring member 10 supplies power to devices and sends signals between devices by transmitting electricity or light. The wiring member 10 includes a plurality of connectors 20, a plurality of linear transmission members 30, and a sheet 40. Each connector 20 is connected to a mating connector 80 provided on a connecting partner. Each linear transmission member 30 connects the connectors 20 to each other. At least a middle section of the linear transmission member 30 is fixed to the sheet 40.

[0023] The connector 20 may be any connector as long as it can be electrically (or optically) connected to the mating connector 80. For example, the connector 20 may include connector terminals and a connector housing. The connector 20 and the mating connector 80 are mated, and the connector terminals are connected to the connector terminals of the mating connector 80. Typically, one connector 20 is provided with multiple connector terminals. The connector housing holds the connector terminals in a position that allows them to be connected to the connector terminals of the mating connector 80. The connector housing holds the multiple connector terminals in a predetermined order. When the wiring member 10 transmits electricity, the connector terminals are typically made of a conductor such as metal, and the connector housing is made of an insulator such as resin. The connector terminals may be connected to the ends of electric wires by crimping or the like. In the example shown in FIG. 1, the wiring member 10 includes four connectors 20. Of course, the number of connectors 20 included in the wiring member 10 is not limited to this and may be three or less, or five or more.

[0024] The linear transmission member 30 is a linear member that transmits electricity, light, or the like. The linear transmission member 30 includes a transmission line body and a coating layer. The transmission line body is a transmission path that transmits electricity or light. For example, if the linear transmission member 30 is an electric wire, the transmission line body is a conductor core wire. The conductor core wire is composed of one or more element wires. The element wires are formed from materials such as copper, copper alloy, aluminum, aluminum alloy, etc. Furthermore, for example, if the linear transmission member 30 is an optical fiber, the transmission line body is composed of a core and cladding. The coating layer covers the transmission line body. The resin material that constitutes the coating layer is not particularly limited and can be set as appropriate. For example, the linear transmission member 30 may be a general electric wire having a core wire and a coating layer surrounding the core wire, or may be a shielded wire, twisted wire, enameled wire, nichrome wire, optical fiber, etc.

[0025] The linear transmission member 30 that transmits electricity may be any of various signal lines and power lines. A part of the linear transmission member 30 that transmits electricity may be used as an antenna, a coil, or the like that sends or receives a signal or power to or from space.

[0026] Furthermore, the linear transmission member 30 may be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member 30 with one transmission path. The linear transmission member 30 may be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A multi-core wire is a linear transmission member 30 with multiple transmission paths. A multi-core wire may be, for example, a twisted wire, a cable in which multiple linear objects are assembled and covered with a sheath, or the like.

[0027] The multiple linear transmission members 30 connect the four connectors 20 together. Hereinafter, when it is necessary to distinguish between the four connectors 20, they may be referred to as connectors 20A, 20B, 20C, and 20D. Of the multiple linear transmission members 30, the linear transmission member 30 having one end connected to connector 20A is referred to as linear transmission member 30A. Of the multiple linear transmission members 30, the linear transmission member 30 having one end connected to connector 20B is referred to as linear transmission member 30B. The linear transmission member 30A and the linear transmission member 30B extend parallel to each other on the sheet 40 so that the end of the linear transmission member 30A connected to connector 20A and the end of the linear transmission member 30B connected to connector 20B face toward a first end 41 of the sheet 40. Either connector 20A or 20B is an example of a first connector, and the other is an example of a second connector. One of the linear transmission members 30A and 30B is an example of a first linear transmission member, and the other is an example of a second linear transmission member.

[0028] In the example shown in FIG. 1 , both ends of the linear transmission members 30A, 30B extend outward from a first end 41 and a second end 42 of the sheet 40. The connectors 20A, 20B are provided on the outside of the sheet 40. The connectors 20A, 20B are provided away from the sheet 40. The connectors 20A, 20B are not fixed to the sheet 40. The ends of the linear transmission members 30A, 30B may be located on the sheet 40. The connectors 20A, 20B may be provided on the sheet 40. The connectors 20A, 20B may be fixed to the sheet 40.

[0029] In this example, the other end of the linear transmission member 30A and the other end of the linear transmission member 30B are connected to the connector 20C or the connector 20D while branching at the branching portion 32. The sections including one end of the linear transmission members 30A and 30B extend in the same direction from the branching portion 32 toward the connectors 20A and 20B.

[0030] The portions of the linear transmission members 30A, 30B between the sheet 40 and the connectors 20C, 20D are wrapped with adhesive tape T to bind them together. The branched shape of the branching portion 32 is maintained by the adhesive tape T. The portions of the linear transmission members 30A, 30B between the sheet 40 and the connectors 20A, 20B are not wrapped with tape. The portions between the sheet 40 and the connectors 20A, 20B may be wrapped with tape.

[0031] An exterior member different from the adhesive tape T may be attached between the sheet 40 and the connectors 20A and 20B, and between the sheet 40 and the connectors 20C and 20D of the linear transmission members 30A and 30B. Such an exterior member may be, for example, a protective sheet, a protective tube, or a resin molded protector.

[0032] In the example shown in FIG. 2, the number of linear transmission members 30A and the number of linear transmission members 30B are both three. The number of linear transmission members 30A, 30B can be set appropriately. The number of linear transmission members 30A, 30B may be two or less, or may be four or more. The number of linear transmission members 30A, 30B does not have to be the same.

[0033] The linear transmission members 30A, 30B are fixed to the sheet 40. The linear transmission members 30A, 30B are lined up on a first surface of the sheet 40. A plurality of linear transmission members 30A, 30B are held lined up on the first surface of the sheet 40. As a result, the height dimension of the wiring member 10 is reduced relative to the width and length dimensions in the portion where the sheet 40 is located, making it flat.

[0034] The sheet 40 is not particularly limited in material, structure, etc. as long as it can fix the linear transmission member 30. Regarding the material constituting the sheet 40, the sheet 40 is formed from a resin material here. Materials other than resin, such as metals and inorganic substances, may also be used as the material constituting the sheet 40. Regarding the structure of the sheet 40, the sheet 40 has a two-layer structure here. The structure of the sheet 40 may be a single-layer structure or a multi-layer structure of three or more layers.

[0035] The sheet 40 includes a first layer and a second layer. The first layer is a fusion layer. The linear transmission member 30 is fused and fixed to the fusion layer. The fusion layer includes a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer softens and is fused to the fusion partner. The type of such resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used.

[0036] The structure of the bonding layer is not particularly limited. For example, the bonding layer may be a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). For example, the bonding layer may be a foamed sheet. For example, the bonding layer may be a fibrous sheet such as a knitted fabric, a woven fabric, or a non-woven fabric. One surface of the first layer is the first side of the sheet 40.

[0037] The second layer may be formed of a different material or have a different structure than the adhesive layer. The second layer enhances the functionality of the adhesive layer or adds functionality not present in the adhesive layer to the sheet 40. The material constituting the second layer may be any of the materials described for the adhesive layer above, as well as metals, inorganic materials, etc. The structure of the second layer may be any of the structures described for the adhesive layer above. One surface of the second layer is the second side of the sheet 40.

[0038] The first and second layers are fixed together while the other surface of the first layer and the other surface of the second layer are in contact with each other. The manner in which the first and second layers are fixed together is not particularly limited, but they may be fixed together by fusion or adhesion. For example, if at least one of the first and second layers is a sheet with voids on its surface, such as a fiber sheet or a foam sheet, a resin material or adhesive can fill the voids and fix the layers together. This produces a so-called anchor effect, firmly fixing the first and second layers together.

[0039] Here, the first layer is described as a solid resin sheet, and the second layer is described as a fibrous sheet. Here, the first and second layers are described as being fused together. That is, the resin of the first layer penetrates between the fibers of the second layer in a fluid state and then hardens. This maintains the state in which the resin of the first layer penetrates between the fibers of the second layer, firmly fixing the first and second layers together.

[0040] The first and second layers are formed to have the same size (same planar shape). One of the first and second layers may be formed larger than the other. The first and second layers are fixed over the entire contact area. The first and second layers may be fixed over only a portion of the contact area.

[0041] The sheet 40 may be a soft material. For example, the first layer may be a solid sheet made of a soft resin such as soft PVC, and the second layer may be a nonwoven fabric made of PET, making the sheet 40 a soft material. The sheet 40 has flexibility that allows it to follow the bending of the linear transmission member 30. The wiring member 10 can be bent in the thickness direction (bending such that the folds are along the main surface of the sheet 40). The sheet 40 is foldable. The wiring member 10 can be folded back at the position of the sheet 40, along with the linear transmission member 30 and the sheet 40.

[0042] The wiring member 10 corresponds to a different product number by partially folding back the linear transmission member 30 and the sheet 40. In the present disclosure, multiple product numbers result from the different paths of some of the linear transmission members 30. The paths of the linear transmission members 30 are set according to the positions of the components to which they are connected. Hereinafter, when it is necessary to distinguish between wiring members 10 according to their product number, additional reference numerals are used to distinguish them. For example, in the wiring member 10N shown in FIG. 2, the linear transmission member 30 and the sheet 40 are not partially folded back. For example, the wiring member 10F shown in FIG. 3 is formed by partially folding back the linear transmission member 30 and the sheet 40 of the wiring member 10N. The wiring member 10F is derived from the wiring member 10N. In the present disclosure, the wiring member 10N and at least one wiring member 10F derived from the wiring member 10N are collectively referred to as the wiring member 10 when no distinction is necessary.

[0043] The sheet 40 is formed into a shape corresponding to one product number. The paths of the linear transmission members 30A, 30B on the sheet 40 correspond to the one product number. The sheet 40 is formed into a shape corresponding to the paths of the linear transmission members 30A, 30B corresponding to one product number. By fixing the linear transmission members 30A, 30B to the sheet 40, the linear transmission members 30A, 30B are maintained in a state along the wiring path corresponding to one product number. In the example shown in FIG. 1 , the sheet 40 maintains the straight paths of the linear transmission members 30A, 30B. The sheet 40 is formed into a shape corresponding to the straight paths. By folding back and deforming a portion of the linear transmission members 30 and the sheet 40, the paths of some of the linear transmission members 30 change, making it possible to accommodate a different product number.

[0044] The sheet 40 and the linear transmission member 30 may be fixed in any manner. Such a fixing manner may be contact-part fixing, non-contact-part fixing, or a combination of both. Here, contact-part fixing means that the sheet 40 and the linear transmission member 30 are fixed by adhering to each other at their contacting portions. Non-contact-part fixing means a fixing manner that is not contact-part fixing, such as using a sewing thread, a cover, or an adhesive tape to press the linear transmission member 30 toward the sheet 40 or to sandwich the sheet 40 and the linear transmission member 30 together, thereby maintaining that state. In the following description, the sheet 40 and the linear transmission member 30 are described as being in a contact-part fixing state.

[0045] The manner of fixing the contact portions may be indirect fixing of the contact portions, direct fixing of the contact portions, or a combination of both in different regions. Here, indirect fixing of the contact portions means that the sheet 40 and the linear transmission member 30 are indirectly fixed to each other via an adhesive material such as an adhesive, pressure-sensitive adhesive, or double-sided adhesive tape provided between them. Direct fixing of the contact portions means that the sheet 40 and the linear transmission member 30 are directly fixed to each other without the use of a separate adhesive or the like. In direct fixing of the contact portions, for example, the sheet 40 and the linear transmission member 30 may be fixed to each other by melting a resin contained in at least one of the sheet 40 and the linear transmission member 30.

[0046] When such a state of direct fixation of the contact regions is formed, the resin may be melted by, for example, heat or a solvent. That is, the state of direct fixation of the contact regions may be a state of direct fixation of the contact regions by heat or a state of direct fixation of the contact regions by a solvent. Preferably, the state of direct fixation of the contact regions is a state of direct fixation of the contact regions by heat.

[0047] The means for directly fixing the contact areas is not particularly limited, and known means such as welding, fusion, and welding can be used. Here, the sheet 40 and the linear transmission member 30 are fused together. In this case, the fusion layer of the sheet 40 is fused to the outermost layer of the linear transmission member 30. The outermost layer of the linear transmission member 30 is the coating layer. It is preferable that the materials of the coating layer and the fusion layer are compatible. Here, the resin material constituting the coating layer is the same type as the resin material constituting the fusion layer. For example, the resin material constituting the fusion layer and the resin material constituting the coating layer are PVC or polyolefin.

[0048] Each linear transmission member 30A, 30B is directly fixed to the sheet 40 at the contact portion without relying on other linear transmission members 30. Even if the state of direct fixation at the contact portion of one of the multiple linear transmission members 30A, 30B is released, the state of direct fixation at the contact portion of the other linear transmission members is not released.

[0049] The fixing portion between the sheet 40 and the linear transmission member 30 is provided continuously along the extension direction of the linear transmission member 30. The fixing portion between the sheet 40 and the linear transmission member 30 may be provided over the entire length of the sheet 40. The fixing portion between the sheet 40 and the linear transmission member 30 may be provided at multiple locations spaced apart along the extension direction of the linear transmission member 30.

[0050] The sheet 40 has a tear line 45 formed therein. The tear line 45 is provided for tearing the sheet 40. Tearing the sheet 40 using the tear line 45 is easier than tearing the sheet 40 at a location without the tear line 45. The tear line 45 is formed by processing a portion of the sheet 40. In this example, the tear line 45 is a perforation 45. A plurality of cuts 46 are formed intermittently in a predetermined direction to form the perforation 45. The tear line 45 does not have to be a perforation 45, and may be anything that makes it easier to tear the sheet 40. For example, the tear line 45 may be a groove in which a portion of the sheet 40 is recessed in the thickness direction. By forming a groove, the force acting to tear the sheet 40 is more likely to be concentrated in the groove.

[0051] The tear line 45 extends between the linear transmission members 30A and 30B. On the sheet 40, the linear transmission members 30A and 30B are arranged in the parallel direction at intervals. The three linear transmission members 30A are arranged in the parallel direction at intervals. The three linear transmission members 30B are arranged in the parallel direction at intervals. Each interval can be set appropriately. Here, the interval between the linear transmission members 30A is the same as the interval between the linear transmission members 30B. The interval between the linear transmission members 30A and 30B is larger than the interval between the linear transmission members 30A. The interval between the linear transmission members 30A and 30B may be the same as or smaller than the interval between the linear transmission members 30A. The three linear transmission members 30A may be arranged in contact with each other in the parallel direction.

[0052] One end of the tear line 45 reaches the edge of the first end 41. If the tear line 45 is a perforation, "one end of the tear line 45 reaching the edge of the first end 41" includes not only the case where the slit 46 is at the edge of the first end 41, but also the case where the slit 46 is not at the edge of the first end 41 but is slightly inward from the edge of the first end 41. In this example, the other end of the tear line 45 reaches the edge of the second end 42. Therefore, the tear line 45 extends along the entire longitudinal direction of the sheet 40. The other end of the tear line 45 does not have to reach the edge of the second end 42.

[0053] The side edge 43 of the seat 40 and the linear transmission member 30 are spaced apart. A margin portion 44 is formed in the seat 40 between the side edge 43 of the seat 40 and the linear transmission member 30. The margin portion 44 may be used, for example, when fixing the seat 40 to a vehicle. The width dimension of the margin portion 44, i.e., the distance between the side edge 43 of the seat 40 and the linear transmission member 30, can be set as appropriate. Here, the width dimension of the margin portion 44 is larger than the distance between the linear transmission members 30A. The width dimension of the margin portion 44 is larger than the distance between the linear transmission members 30A, 30B.

[0054] <About handling multiple product numbers> The following will explain how the wiring member 10 can be used to handle a plurality of product numbers.

[0055] <First product number> The first product number is a wiring member 10N that is not folded back, as shown in Fig. 2. In the wiring member 10N, the tear line 45 is not torn. In the wiring member 10N, the tear line 45 may be torn to the extent that the torn and separated sheet portions cannot be folded back. The mating connectors 80A, 80B of the connectors 20A, 20B in the wiring member 10N are both located outside the first end 41.

[0056] <Second part number> The second product number will be described with further reference to FIGS. 3 and 4. The second product number is a wiring member 10F that is folded back. FIG. 3 is a diagram showing a wiring member 10F corresponding to the second product number. FIG. 4 is a diagram showing the manufacturing process of a wiring member 10F corresponding to the second product number. Hereinafter, when it is necessary to distinguish between multiple wiring members 10F that are folded back and have different folding patterns, they may be referred to as wiring members 10F1, 10F2, etc. Furthermore, when it is not necessary to distinguish between wiring members 10F1 and 10F2, they may be collectively referred to as wiring members 10F.

[0057] In the wiring member 10F, the sheet 40 is torn along the tear line 45 and separated into two sheet portions 50A and 50B. A linear transmission member 30A is fixed to the sheet portion 50A. A linear transmission member 30B is fixed to the sheet portion 50B. One of the sheet portions 50A and 50B is an example of a first sheet portion, and the other is an example of a second sheet portion. When only one of the two sheet portions 50A and 50B is folded back, the folded back portion is the first sheet portion.

[0058] In the wiring member 10F1 of this example, the sheet portion 50A is folded back to form a folded back portion 54. The folded back portion 54 is folded back so as to move away from the sheet portion 50B. The folded back portion 54 does not overlap with the sheet portion 50B. In the wiring member 10F1, the mating connector 80B of the connector 20B is located outside the first end 41, and the mating connector 80A of the connector 20A is located outside the side edge 43.

[0059] At the folded portion of the sheet portion 50A, the overlapping sheets 40 are fixed together to form a sheet fixing portion 56. The folded portion 54 and the unfolded portion overlap. In this example, the sheet portions 50A overlap. The sheet portions 50A are fixed together at the sheet fixing portion 56. The fixing manner at the sheet fixing portion 56 is not particularly limited and can be set as appropriate. For example, the sheet fixing portion 56 may be fixed in any of the fixing manners described above for the fixing manner between the sheet 40 and the linear transmission member 30.

[0060] In this example, the overlapping sheets 40 are fused and fixed together. In this example, the overlapping portions of the sheet portions 50A, which do not have the linear transmission member 30 therebetween, are fused together. In the example shown in Fig. 3, the opposing margin portions 44 are fused together.

[0061] In the example shown in Fig. 3, the sheet 40 is torn to the middle between the first end 41 and the second end 42. The sheet 40 has an untorn sheet main body 52. ​​The sheet portions 50A and 50B are continuous with the sheet main body 52. ​​The sheet portion 50A is continuous with one side of the sheet main body 52 in the width direction, and the sheet portion 50B is continuous with the other side.

[0062] 3, the wiring member 10F1 is folded back so that the linear transmission member 30 faces inward and the sheet portion 50A faces outward. The wiring member 10F1 may also be folded back so that the linear transmission member 30 faces outward and the sheet portion 50A faces inward.

[0063] In the wiring member 10F1, the extending direction of the folded sheet portion 50A is perpendicular to the extending direction of the unfolded sheet portion 50A. In this case, the fold extends in a direction that forms a 45-degree angle with the extending direction of the unfolded sheet portion 50A.

[0064] To manufacture the wiring member 10F1, first prepare the wiring member 10N. The sheet 40 is torn from the first end 41 using the tear line 45 of the wiring member 10N. The tearing distance of the sheet 40 is determined according to the product number. In the example shown in FIG. 4, the sheet 40 is torn up to the middle of the tear line 45. As the sheet 40 is torn, the tear line 45 forms a slit 48, which separates the sheet 40 into two sheet portions 50A and 50B. One of the sheet portions 50A and the linear transmission member 30A disposed on the sheet portion 50A are folded back. In the example shown in FIG. 4, a fold L corresponding to the product number is indicated. The fold L is an imaginary line and is not a line formed in the wiring member 10. The fold-back overlapping sheets 40 are then fixed together. Here, the sheet portions 50A are fused together. This completes the manufacturing of the wiring member 10F1.

[0065] <Third product number> The third part number will be described with further reference to Figures 5 and 6. Figure 5 is a diagram showing a wiring member 10F2 corresponding to the third part number. Figure 6 is a diagram showing a process of manufacturing the wiring member 10F2 corresponding to the third part number.

[0066] The wiring member 10F2 of this example is also folded back, but the folding back manner of the wiring member 10F2 of this example is different from the folding back manner of the wiring member 10F1.

[0067] In the wiring member 10F2, the sheet portion 50B is folded back to form a folded back portion 54. The sheet portion 50B is folded back so as to straddle the sheet portion 50A. In the wiring member 10F2, the mating connector 80A of the connector 20A is located outside the first end 41, and the mating connector 80B of the connector 20B is located outside the side edge 43.

[0068] The overlapping sheet portions 50A and 50B are fixed together at the sheet fixing portion 56. The margin portion 44 of the sheet portion 50A is fixed to the margin portion 44 of the sheet portion 50B. The sheet fixing portion 56 of the wiring member 10F2 can be located farther from the fold in the direction perpendicular to the fold than the sheet fixing portion 56 of the wiring member 10F1. This makes it difficult for the overlapping sheets 40 to unfold in areas other than the sheet fixing portion 56. The sheet fixing portion 56 of the wiring member 10F1 may be located at a position similar to that of the wiring member 10F2. For example, in the wiring member 10F1, the margin portion 44 between the side edge 43 of the sheet 40 formed by tearing the tear line 45 and the linear transmission member 30 may be fused to the margin portion 44 between the side edge 43 of the original sheet 40 and the linear transmission member 30.

[0069] To manufacture the wiring member 10F2, first prepare the wiring member 10N. The sheet 40 is torn from the first end 41 using the tear line 45 of the wiring member 10N. The tearing distance of the sheet 40 is determined according to the product number. In the example shown in FIG. 6, the sheet 40 is torn up to the middle of the tear line 45. As the sheet 40 is torn, the tear line 45 forms a slit 48, which separates the sheet 40 into two sheet portions 50A and 50B. One of the sheet portions 50B and the linear transmission member 30B disposed on the sheet portion 50B are folded back. In the example shown in FIG. 6, a fold L corresponding to the product number is indicated. The fold L is an imaginary line and is not a line formed in the wiring member 10. The fold-back overlapping sheets 40 are then fixed together. Here, the sheet portions 50A and 50B are fused together. This completes the manufacturing of the wiring member 10F2.

[0070] <Other part numbers> The wiring member 10 of this example can also accommodate product numbers other than the first to third product numbers described above. For example, as shown in FIG. 4 or 6, as the tear line 45 is torn, one of the sheet portions 50A and 50B may extend upward without bending, while the other may be bent to the right. As shown in FIG. 4 or 6, as the tear line 45 is torn, one of the sheet portions 50A and 50B may be bent to the left, while the other may be bent to the right. The bending angle of the sheet portion 50A or the sheet portion 50B may be less than or greater than 90 degrees. The tear line 45 may be torn by a smaller or larger amount than in the illustrated example.

[0071] <Effects, etc.> According to the wiring member 10 configured as described above, the tear wire 45 extends between the linear transmission member 30A and the linear transmission member 30B, and one end of the tear wire 45 reaches the edge of the first end 41. Therefore, by using the tear wire 45 to tear a portion of the sheet 40 from the first end 41 as necessary, the wiring member 10 can accommodate multiple product numbers.

[0072] Furthermore, in the wiring member 10F, the sheet 40 is torn along the tear line 45 to separate into a sheet portion 50A to which the linear transmission member 30A is fixed and a sheet portion 50B to which the linear transmission member 30B is fixed, and the first sheet portion is folded back. This allows for a wiring member 10F that corresponds to a different product number from that obtained when the wiring member 10F is not torn along the tear line 45.

[0073] Furthermore, in the area where the first sheet portion is folded back, the overlapping sheets 40 are fused and fixed together, thereby allowing the wiring member 10F to be easily held in the folded back shape.

[0074] Furthermore, with wiring member 10F2, sheet portion 50B is folded over sheet portion 50A, and overlapping sheet portions 50A and 50B are fixed together. This makes it easy to fix folded portion 54 even when sheet 40 has little free margin 44.

[0075] [Embodiment 2] A wiring member according to a second embodiment will now be described. Fig. 7 is a plan view showing a wiring member 110 according to the second embodiment. Fig. 8 is a plan view showing another part number of the wiring member 110 according to the second embodiment. Fig. 7 shows a wiring member 110N that is not folded back, and Fig. 8 shows a wiring member 110F that is folded back. In the following descriptions of the embodiments and modifications, components similar to those described so far will be assigned the same reference numerals, and descriptions thereof will be omitted.

[0076] In the wiring member 110 of this example, the position of the other end of the tear line 145 is different from the position of the other end of the tear line 45 in the above-described wiring member 10. In the wiring member 110, the other end of the tear line 145 is located in the intermediate region between the first end 41 and the second end 42 of the sheet 140. This prevents the tear line 145 from tearing too much and completely separating the sheet 140 into two pieces.

[0077] In this example, a through hole 47 is formed at the other end of the tear line 145. In this example, the tear line 145 is also a perforation 145. The through hole 47 is larger than each of the slits 46 that make up the perforation 145. The through hole 47 is formed in a circular shape. This prevents the sheet 140 from tearing beyond the other end of the tear line 45. The through hole 47 is formed by punching the sheet 140, for example. A portion of the sheet 140 is removed at the location of the through hole 47. At the location of the slit 46, a portion of the sheet 140 is only cut but not removed. At the location of the slit 46, a portion of the sheet 140 may be removed that is smaller than the through hole 47. Instead of multiple small slits 46, multiple through holes 47 may be formed intermittently to form the perforations 145.

[0078] In this example, the linear transmission members 30A, 30B are fixed to the sheet 140 at multiple locations spaced apart along the extension direction. The sheet 140 and the linear transmission members 30A, 30B are fixed via spot fixing portions 60 that are partially fixed along the extension direction of the linear transmission members 30A, 30B. A plurality of spot fixing portions 60 are provided at intervals from each other along the extension direction of the linear transmission member 30. The intervals between the spot fixing portions 60 are not particularly limited and can be set as appropriate. By using the spot fixing portions 60, the fixing area between the linear transmission member 30 and the sheet 140 is reduced, making the fixing work easier.

[0079] As shown in FIG. 8, in the wiring member 110F, the spot fixing portion 60 between the linear transmission member 30A and the sheet 140 is located at the folded-back portion 54 of the sheet portion 50A. This makes it difficult for the linear transmission member 30A to separate from the sheet portion 50A when it is folded back together with the sheet portion 50A. This makes it difficult for the linear transmission member 30A to get caught on surrounding members. Furthermore, the spot fixing portion 60 is located in the area where the folded-back portion 54 and the unfolded portion overlap. This makes it even more difficult for the linear transmission member 30A to separate from the sheet portion 50A when it is folded back together with the sheet portion 50A.

[0080] The wiring member 110F shown in Fig. 8 corresponds to the wiring member 10F1 shown in Fig. 3. Of course, a wiring member that is folded in a different way from the wiring member 110F may be manufactured.

[0081] [Embodiment 3] A wiring member according to a third embodiment will now be described. Fig. 9 is a schematic plan view showing a wiring member 210 according to the third embodiment. Fig. 10 is a partial enlarged view of Fig. 9, showing a wiring member 210N corresponding to a first product number. Fig. 11 is a view showing a wiring member 210F1 corresponding to a second product number. Fig. 12 is a view showing a wiring member 210F2 corresponding to a third product number.

[0082] In the wiring member 210 of this example, the planar shape of the sheet 240 is different from the planar shape of the sheet 40 in the wiring member 10. In the example shown in FIG. 9, the paths of the linear transmission members 30A and 30B on the sheet 240 are configured by a combination of straight paths and curved paths. The sheet 240 is also formed in a shape that combines straight paths and curved paths. Furthermore, portions of the multiple linear transmission members 30, including the branching portions 32, are fixed to the sheet 240. This maintains the shape of the branching portions 32. The sheet 240 is also formed in a branched shape corresponding to the branching portions 32. Most of the section along the extension direction of the linear transmission members 30 is fixed to the sheet 240, so that most of the path of the linear transmission members 30 can be maintained similar to the predetermined path in the vehicle. This allows the linear transmission members 30 to be easily routed along the predetermined path when the wiring member 210 is assembled to the vehicle.

[0083] The wiring member 210 of this example differs from the above-described wiring member 10 in that it has an intersection 34. The intersection 34 is a portion where the linear transmission members 30A and 30B intersect on the sheet 240. The intersection 34 is located to avoid the tear line 245. The intersection 34 is located farther from the first end 41 than the other end of the tear line 245. This makes it less likely that the linear transmission members 30 will cross the tear line 245 in the wiring member 210, and prevents the intersection 34 from interfering with the tear line 245 when the sheet 240 is torn. In the wiring member 210, no linear transmission members 30 cross the tear line 245. The linear transmission members 30A and 30B do not cross the tear line 245.

[0084] For example, the intersection 34 is provided to change the order of the linear transmission members 30A and 30B. In the example shown in Fig. 9, the linear transmission member 30A connecting the connectors 20A and 20C and the linear transmission member 30B connecting the connectors 20B and 20D intersect at the intersection 34. The linear transmission members 30A and 30B having the other ends connected to the same connector 20 (for example, connector 20C) may intersect at the intersection 34.

[0085] The intersection 34 and the spot fixing portion 60 may be applied to one wiring member. In this case, as shown in Fig. 10, the spot fixing portion 60 may be provided at positions sandwiching the intersection 34 in the linear transmission members 30A and 30B that constitute the intersection 34.

[0086] 10 , in the wiring member 210 of this example, a through hole 47 is formed in the sheet 240 at a position in the middle of the tear line 245. As a result, the tearing of the sheet 240 by the tear line 245 is interrupted at the position of the through hole 47 in the middle. Furthermore, when the tearing amount of the tear line 245 varies depending on the product number, the through hole 47 can be used as a guide for the tearing amount of the tear line 245. The through hole 47 may have the same configuration as the through hole 47 provided at the other end of the tear line 245.

[0087] In the wiring member 210F1 shown in FIG. 11, the tear line 245 is torn up to the through-hole 47 in the middle, and the sheet portion 250A1 is folded back to form the folded-back portion 54. In this case, the presence of the through-hole 47 makes it possible to keep the tearing amount constant even when the tear line 45 is torn up to the middle. Furthermore, the tear line 245 remains between the through-hole 47 in the middle and the other end of the tear line 245. Even in this case, the presence of the through-hole 47 in the middle prevents the remaining tear line 245 from tearing starting from the torn portion.

[0088] 12, the tear wire 245 is torn up to the through-hole 47 at the other end, and the sheet portion 250A2, which is longer than the sheet portion 250A1, is folded back to form the folded back portion 54. Of course, wiring members that are folded back in a manner different from that of the wiring members 210F1 and 210F2 may also be manufactured.

[0089] [Embodiment 4] A wiring member according to embodiment 4 will be described below. Fig. 13 is a schematic plan view showing a wiring member 310 according to embodiment 4. Fig. 14 is a partially enlarged view of Fig. 13.

[0090] The wiring member 310 of this example differs from the above-described wiring member 10 in that it further includes a linear transmission member 30AB. The linear transmission member 30AB connects the connector 20A and the connector 20B. One end of the linear transmission member 30AB is connected to the connector 20A. The other end of the linear transmission member 30AB is connected to the connector 20B. The linear transmission member 30AB is an example of a third linear transmission member.

[0091] An intermediate portion of the linear transmission member 30AB makes a U-turn on the sheet 240. The linear transmission member 30AB has a U-turn portion 36. The U-turn portion 36 is located farther from the first end 41 than the other end of the tear wire 45. The linear transmission member 30AB extends on one side of the tear wire 245 on the sheet 240 from the U-turn portion 36 toward one end connected to the connector 20A. The linear transmission member 30AB extends on the other side of the tear wire 245 on the sheet 240 from the U-turn portion 36 toward the other end connected to the connector 20B. This allows for a simple configuration to accommodate multiple part numbers, even when there is a linear transmission member 30AB connecting the connectors 20A and 20B.

[0092] The U-turn portion 36 and the spot fixing portion 60 may be applied to one wiring member. In this case, as shown in Fig. 14, the spot fixing portions 60 may be provided in positions before and after the U-turn portion 36 in the linear transmission member 30AB. This makes it difficult for the portion of the linear transmission member 30AB including the U-turn portion 36 to float from the sheet 240.

[0093] 13 shows the wiring member 310 that is not folded back. The wiring member 310 can be made into a folded wiring member by applying the various folding modes described above.

[0094] [Note] The configurations described in the above embodiments and modified examples can be combined as appropriate as long as they are not mutually contradictory. For example, in embodiment 1, the fixed portion between the sheet 40 and the linear transmission member 30 may be a spot fixed portion 60. Also, for example, in embodiments 2, 3, and 4, the fixed portion between the sheet 140, 240 and the linear transmission member 30 may be continuous along the extension direction of the linear transmission member 30. Also, for example, the intersection portion 34 and the U-turn portion 36 may be applied to a single wiring member. [Explanation of symbols]
