DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Description of the embodiments of the present disclosure] First, the 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 in parallel on the sheet so that an end of the first linear transmission member connected to the first connector and an end of the second linear transmission member connected to the second connector extend toward a first end on the sheet, and a tear line for tearing the sheet is formed in 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 an 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 necessary.

[0012] (2) In the wiring member of (1), the other end of the tear line may be located in a middle 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, a middle portion of the third linear transmission member being located farther from the first end than the tear line, and the third linear transmission member may extend from the middle portion of the third linear transmission member toward the one end on one side of the tear line in the sheet, and extend from the middle portion of the third linear transmission member toward the other end on the other side of the tear line in the sheet. This makes it possible to easily accommodate multiple part 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 through hole. In addition, when the amount of tearing of the tear line varies depending on the part number, the through hole can be used as a guide for the amount of tearing of the tear line.

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

[0016] (6) In any one of the wiring members (1) to (5), the sheet may be torn at the tear line 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 product number different from that in the case where the wiring member is not torn at the tear line.

[0017] (7) In the wiring member of (6), the overlapping sheets may be fused and fixed to each other in a portion where the first sheet portion is folded back, thereby making it possible to easily hold the wiring member in a folded shape.

[0018] (8) In the wiring member of (6) or (7), the first sheet portion may be folded over to straddle 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 the sheet has a small free margin.

[0019] (9) In any one of the wiring members (6) to (8), the first linear transmission member may be fixed to the sheet at a plurality of points spaced apart along the extending direction, and the fixed points between the first linear transmission member and the sheet may be in a folded-back portion of the first sheet portion, so that the first linear transmission member is less likely to separate from the first sheet portion when folded back together with the first sheet portion.

[0020] [Details of the embodiment of the present disclosure] Specific examples of the wiring member of 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 equivalent to the claims.

[0021] [Embodiment 1] Hereinafter, a description will be given of 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 connection 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 electrically (or optically) connectable to the mating connector 80. For example, the connector 20 may include a connector terminal and a connector housing. The connector 20 and the mating connector 80 are fitted together, and the connector terminal is connected to the connector terminal of the mating connector 80. Usually, one connector 20 is provided with a plurality of connector terminals. The connector housing holds the connector terminal in a position that allows connection with the connector terminal of the mating connector 80. The connector housing holds the plurality of connector terminals in a predetermined order. When the wiring member 10 transmits electricity, the connector terminal is usually made of a conductor such as metal, and the connector housing is made of an insulator such as resin. The connector terminal may be connected to the end of an electric wire 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 or light. 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, when 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 strands. The strands are formed of copper, copper alloy, aluminum, aluminum alloy, or the like. For example, when the linear transmission member 30 is an optical fiber, the transmission line body is a core and clad. The coating layer covers the transmission line body. The resin material that constitutes the coating layer is not particularly limited and can be set appropriately. For example, the linear transmission member 30 may be a general electric wire having a core wire and a coating layer around the core wire, or may be a shielded wire, a twisted wire, an enamel wire, a nichrome wire, an optical fiber, or the like.

[0025] The linear transmission member 30 that transmits electricity may be any of various signal lines and various 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 transmits a signal or power to or receives it 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. The multiple linear transmission members 30, one end of which is connected to the connector 20A, are referred to as linear transmission members 30A. The multiple linear transmission members 30, one end of which is connected to the connector 20B, are referred to as linear transmission members 30B. The linear transmission members 30A and 30B extend in parallel on the sheet 40 so that the end of the linear transmission member 30A connected to the connector 20A and the end of the linear transmission member 30B connected to the connector 20B are directed toward the first end 41 on the sheet 40. Either the connectors 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. 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 numbers of linear transmission members 30A, 30B can be set appropriately. The numbers of linear transmission members 30A, 30B may be two or less, or four or more. The numbers of linear transmission members 30A, 30B do 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. The multiple linear transmission members 30A, 30B are held in a lined up state 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 is capable of fixing the linear transmission member 30. Regarding the material constituting the sheet 40, the sheet 40 is formed of a resin material here. The material constituting the sheet 40 may be a material other than resin, such as a metal or an inorganic material. 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 one-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 fusion layer is not particularly limited. For example, the fusion layer may be a sheet having a uniform solid cross section (also called a non-foamed sheet or solid sheet). For example, the fusion layer may be a foamed sheet or the like. For example, the fusion 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 surface of the sheet 40.

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

[0038] The first layer and the second layer 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 layer and the second layer 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 layer and the second layer is a sheet having voids on the surface, such as a fiber sheet or a foam sheet, a resin material or an adhesive can be inserted into the voids to fix them together. This produces a so-called anchor effect, and the first layer and the second layer are firmly fixed 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 layer and the second layer are described as being fused together. In other words, the resin of the first layer is hardened after penetrating between the fibers of the second layer in a fluid state. This maintains the state in which the resin of the first layer is penetrating between the fibers of the second layer, and the first layer and the second layer are firmly fixed together.

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

[0041] The sheet 40 may be a soft member. For example, the first layer is a solid sheet made of a soft resin such as soft PVC, and the second layer is a nonwoven fabric made of PET, so that the sheet 40 is a soft member. 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 fold is 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, including the linear transmission member 30 and the sheet 40.

[0042] The wiring member 10 corresponds to a different part number by folding back a part of the linear transmission member 30 and the sheet 40. The multiple part numbers in the present disclosure are generated by the different paths of some of the linear transmission members 30. The path of the linear transmission member 30 is set according to the position of the component to which it is connected. In the following, when it is necessary to distinguish the wiring members 10 for each part number, a reference symbol is added to distinguish them. For example, in the wiring member 10N shown in FIG. 2, a part of the linear transmission member 30 and the sheet 40 are not folded back. Also, for example, the wiring member 10F shown in FIG. 3 is formed by folding back a part of the linear transmission member 30 and the sheet 40 in 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 path of the linear transmission members 30A, 30B in the sheet 40 corresponds to the one product number. The sheet 40 is formed into a shape according to the path of the linear transmission members 30A, 30B corresponding to one product number. The linear transmission members 30A, 30B are fixed to the sheet 40, so that the linear transmission members 30A, 30B are kept 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 path of the linear transmission members 30A, 30B. The sheet 40 is formed into a shape according to the straight path. The linear transmission members 30 and a part of the sheet 40 are folded and deformed, so that the path of a part of the linear transmission members 30 changes, making it possible to correspond to another product number.

[0044] The sheet 40 and the linear transmission member 30 may be fixed in any manner. Such a fixing manner may be fixation at the contact portion, fixation at the non-contact portion, or a combination of both. Here, the contact portion fixing means that the contact portion of the sheet 40 and the linear transmission member 30 are fixed by adhering to each other. Moreover, the non-contact portion fixing means a fixing manner that is not a contact portion fixing, for example, a sewing thread, a cover, an adhesive tape, or the like holds the linear transmission member 30 against the sheet 40, or sandwiches the sheet 40 and the linear transmission member 30, and maintains the state. In the following, the sheet 40 and the linear transmission member 30 will be described as being in a contact portion fixing state.

[0045] The manner of fixing the contact parts may be indirect fixing of the contact parts, direct fixing of the contact parts, or both may be used in different regions. Here, indirect fixing of the contact parts means that the sheet 40 and the linear transmission member 30 are indirectly attached and fixed via an adhesive member such as an adhesive, a pressure sensitive adhesive, or a double-sided adhesive tape provided between them. Direct fixing of the contact parts means that the sheet 40 and the linear transmission member 30 are directly attached and fixed without using an adhesive or the like provided separately. In direct fixing of the contact parts, for example, it is considered that the sheet 40 and the linear transmission member 30 are attached and fixed by melting a resin contained in at least one of them.

[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] At this time, the means for forming the state in which the contact parts are directly fixed is not particularly limited, and known means such as fusing, fusion, welding, etc. can be used. Here, the sheet 40 and the linear transmission member 30 are fused. In this case, the fusion layer of the sheet 40 and the outermost layer of the linear transmission member 30 are fused. In the linear transmission member 30, the outermost layer is a coating layer. It is preferable that the material of the coating layer and the material of 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 being connected to other linear transmission members 30. Even if the state of direct fixation at the contact portion of any 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 fixed 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 fixed portion between the sheet 40 and the linear transmission member 30 may be provided over the entire length of the sheet 40. The fixed 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 is formed with a tear line 45. 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 part of the sheet 40. Here, the tear line 45 is formed as 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 the perforation 45, and may be any that facilitates tearing the sheet 40. For example, the tear line 45 may be a groove in which a part of the sheet 40 is recessed in the thickness direction. By forming the groove, the force applied to tearing is easily 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 a parallel direction with a gap between them. The three linear transmission members 30A are arranged in a parallel direction with a gap between them. The three linear transmission members 30B are arranged in a parallel direction with a gap between them. Each gap can be set appropriately. Here, the gap between the linear transmission members 30A is the same as the gap between the linear transmission members 30B. The gap between the linear transmission members 30A and 30B is larger than the gap between the linear transmission members 30A. The gap between the linear transmission members 30A and 30B may be the same as or smaller than the gap between the linear transmission members 30A. The three linear transmission members 30A may be arranged in contact with each other in a parallel direction.

[0052] One end of the tear line 45 reaches the edge of the first end 41. When the tear line 45 is a perforation, the fact that one end of the tear line 45 reaches the edge of the first end 41 includes the case where the slit 46 is at the edge of the first end 41, as well as the case where the slit 46 is not at the edge of the first end 41 but is slightly inside 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 over the entire length 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 appropriately. 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 part numbers> The following describes how the wiring member 10 can be used to handle a plurality of product numbers.

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

[0056] <Second part number> The second part number will be described with further reference to Figs. 3 and 4. The second part number is a wiring member 10F that is folded back. Fig. 3 is a diagram showing a wiring member 10F corresponding to the second part number. Fig. 4 is a diagram showing a state of manufacturing the wiring member 10F corresponding to the second part number. Hereinafter, when it is necessary to distinguish between the multiple wiring members 10F that are folded back and have different folding patterns, they may be referred to as wiring members 10F1, 10F2, etc. Also, when it is unnecessary to distinguish between the 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 at 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 one that is folded back 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 be 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 portion 41, and the mating connector 80A of the connector 20A is located outside the side edge 43.

[0059] At the folded-back portion of the sheet portion 50A, the overlapping sheets 40 are fixed to each other to form a sheet fixing portion 56. The folded-back portion 54 and the non-folded portion overlap. In this example, the sheet portions 50A overlap each other. The sheet portions 50A are fixed to each other at the sheet fixing portion 56. The fixing manner at the sheet fixing portion 56 is not particularly limited and can be set appropriately. 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, overlapping sheets 40 are fused and fixed to each other. In this example, the sheet portions 50A are fused to each other at overlapping portions where there is no linear transmission member 30 therebetween. In the example shown in Fig. 3, the margin portions 44 facing each other are fused to each other.

[0061] 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 body 52. ​​The sheet portions 50A and 50B are continuous with the sheet body 52. ​​The sheet portion 50A is continuous with one side of the sheet 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 is on the inside and the sheet portion 50A is on the outside. The wiring member 10F1 may be folded back so that the linear transmission member 30 is on the outside and the sheet portion 50A is on the inside.

[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 an angle of 45 degrees with the extending direction of the unfolded sheet portion 50A.

[0064] In manufacturing the wiring member 10F1, first, the wiring member 10N is prepared. The sheet 40 is torn from the first end 41 using the tear line 45 in the wiring member 10N. The amount of tearing of the sheet 40 is set according to the product number. In the example shown in FIG. 4, the sheet 40 is torn to the middle part of the tear line 45. When the sheet 40 is torn, the trace of the tear line 45 becomes a slit 48, and the sheet 40 is divided by the slit 48, and two sheet parts 50A and 50B are generated. One sheet part 50A and the linear transmission member 30A arranged on the sheet part 50A are folded back. In the example shown in FIG. 4, a fold L corresponding to the product number is described. The fold L is a virtual line and is not a line formed in the wiring member 10. The fold L may be formed in the wiring member 10. The folded and overlapping sheets 40 are fixed to each other. Here, the sheet parts 50A are fused to each other. In this way, the wiring member 10F1 is manufactured.

[0065] <Third part number> The third part number will be described with further reference to Fig. 5 and Fig. 6. Fig. 5 is a diagram showing a wiring member 10F2 corresponding to the third part number. Fig. 6 is a diagram showing a state in which the wiring member 10F2 corresponding to the third part number is manufactured.

[0066] The wiring member 10F2 of this example is also folded back. The wiring member 10F2 of this example is folded back in a different manner from 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 portion 41, and the mating connector 80B of the connector 20B is located outside the side edge 43.

[0068] At the sheet fixing portion 56, the overlapping sheet portion 50A and the sheet portion 50B are fixed. The margin portion 44 of the sheet portion 50A and the margin portion 44 of the sheet portion 50B are fixed. The sheet fixing portion 56 of the wiring member 10F2 can be provided farther from the fold along the direction perpendicular to the fold than the sheet fixing portion 56 of the wiring member 10F1. Therefore, the overlapping sheets 40 are less likely to open in the portion other than the sheet fixing portion 56. In the wiring member 10F1, the sheet fixing portion 56 may be provided 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 fusion-fixed to the margin portion 44 between the side edge 43 of the original sheet 40 and the linear transmission member 30.

[0069] In manufacturing the wiring member 10F2, first, the wiring member 10N is prepared. The sheet 40 is torn from the first end 41 using the tear line 45 in the wiring member 10N. The amount of tearing of the sheet 40 is set according to the product number. In the example shown in FIG. 6, the sheet 40 is torn to the middle part of the tear line 45. When the sheet 40 is torn, the trace of the tear line 45 becomes a slit 48, and the sheet 40 is divided by the slit 48, and two sheet parts 50A and 50B are generated. One sheet part 50B and the linear transmission member 30B arranged on the sheet part 50B are folded back. In the example shown in FIG. 6, a fold L corresponding to the product number is described. The fold L is a virtual line and is not a line formed in the wiring member 10. The fold L may be formed in the wiring member 10. The folded and overlapping sheets 40 are fixed to each other. Here, the sheet part 50A and the sheet part 50B are fused together. In this way, the wiring member 10F2 is manufactured.

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

[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, the wiring member 10 can accommodate a plurality of product numbers by tearing a portion of the sheet 40 from the first end 41 using the tear wire 45 as necessary.

[0072] Furthermore, in the wiring member 10F, the sheet 40 is torn at the tear line 45 to be separated 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 provides a wiring member 10F that corresponds to a different product number from the product number when it is not torn at the tear line 45.

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

[0074] Furthermore, according to the wiring member 10F2, the sheet portion 50B is folded back so as to straddle the sheet portion 50A, and the overlapping sheet portions 50A and 50B are fixed together. This makes it easier to fix the folded back portion 54 even when the free margin portion 44 of the sheet 40 is small.

[0075] [Embodiment 2] A wiring member according to the second embodiment will 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 description of each embodiment and each modified example, components similar to those described so far will be given 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-mentioned 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 being torn 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 cuts 46 that form the perforation 145. The through hole 47 is formed in a circular shape. This prevents the sheet 140 from being torn beyond the other end of the tear line 45. The through hole 47 is formed by punching the sheet 140 or the like. A part of the sheet 140 is cut out at the through hole 47. At the cut 46, a part of the sheet 140 is only cut and not cut out. At the cut 46, a part of the sheet 140 may be cut out smaller than the through hole 47. Instead of the multiple small cuts 46, multiple through holes 47 may be intermittently formed to form the perforation 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 parts 60 that are partially fixed along the extension direction of the linear transmission members 30A, 30B. A plurality of spot fixing parts 60 are provided at intervals along the extension direction of the linear transmission member 30. The intervals between the spot fixing parts 60 are not particularly limited and can be set appropriately. By using the spot fixing parts 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. The linear transmission member 30A is less likely 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 portion that is not folded back 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 back in a manner different from that of the wiring member 110F may be manufactured.

[0081] [Embodiment 3] A wiring member according to the third embodiment will 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 part number. Fig. 11 shows a wiring member 210F1 corresponding to a second part number. Fig. 12 shows a wiring member 210F2 corresponding to a third part 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. In addition, the portions of the multiple linear transmission members 30 that include the branching portion 32 are fixed to the sheet 240. This maintains the shape of the branching portion 32. The sheet 240 is also formed in a branched shape that corresponds to the branching portion 32. Most of the section along the extension direction of the linear transmission member 30 is fixed to the sheet 240, and most of the path of the linear transmission member 30 can be maintained as a path similar to a predetermined path in the vehicle. This allows the linear transmission member 30 to be easily arranged along a predetermined path when the wiring member 210 is assembled to the vehicle.

[0083] The wiring member 210 of this example is different from the wiring member 10 in that an intersection 34 is provided. The intersection 34 is a portion where the linear transmission members 30A and 30B intersect on the sheet 240. The intersection 34 is located at a position that avoids 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 difficult for the linear transmission members 30 to straddle the tear line 245 in the wiring member 210, and prevents the intersection 34 from getting in the way when the sheet 240 is torn using the tear line 245. In the wiring member 210, there is no linear transmission member 30 that straddles the tear line 245. The linear transmission members 30A and 30B do not straddle the tear line 45.

[0084] For example, the intersection 34 is provided to change the order of the linear transmission members 30A, 30B. In the example shown in Fig. 9, the linear transmission member 30A connecting the connectors 20A, 20C and the linear transmission member 30B connecting the connectors 20B, 20D intersect at the intersection 34. The linear transmission members 30A, 30B whose other ends are connected to the same connector 20 (for example, the 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 constituting 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 amount of tearing of the tear line 245 varies depending on the product number, the through hole 47 can be used as a guide for the amount of tearing of the tear line 245. The through hole 47 may have the same configuration as the above-mentioned 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. At this time, the through hole 47 allows the tear amount to be a constant value 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 through hole 47 in the middle prevents the remaining tear line 245 from tearing starting from the torn portion.

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

[0089] [Embodiment 4] A description will now be given of a wiring member according to embodiment 4. 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 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] The middle part 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 at a position farther from the first end 41 than the other end of the tear line 45. The linear transmission member 30AB extends on one side of the tear line 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 line 245 on the sheet 240 from the U-turn portion 36 toward the other end connected to the connector 20B. This allows a simple configuration to accommodate multiple part numbers even when there is a linear transmission member 30AB connecting the connector 20A and the connector 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 at 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 turned into a folded wiring member by applying the various folding modes described above.

[0094] [Note] The configurations described in the above embodiments and modifications can be appropriately combined as long as they are not mutually contradictory. For example, in the first embodiment, the fixed portion between the sheet 40 and the linear transmission member 30 may be the spot fixed portion 60. Also, for example, in the second, third, and fourth embodiments, 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 one wiring member. [Explanation of symbols]
