[0019] [Description of Embodiments of the Present Disclosure]

[0020] First, embodiments of the present disclosure will be listed and described.

[0021] The wiring member of the present disclosure is as follows.

[0022] (1) A wiring member includes: a first sheet including a fusion layer; a second sheet; and a first linear transmission member disposed between the first sheet and the second sheet, and the first sheet and the second sheet are fixed via the fusion layer in a direction intersecting the length direction of the first linear transmission member. The first sheet and the second sheet are fixed via the fusion layer in a direction intersecting the length direction of the first linear transmission member, so as to be maintained in a state where the first linear transmission member is disposed between the first sheet and the second sheet. Thus, the linear transmission member can be fixed to the sheet via the fusion layer regardless of the type of the linear transmission member.

[0023] (2) In the wiring member of (1), it may be that a bent portion where the first linear transmission member is bent and disposed on the first sheet is provided, and the second sheet is provided at positions on both sides of the bent portion in the extending direction of the first linear transmission member. Thus, even if the first linear transmission member is pulled along the extending direction, the first linear transmission member and the first sheet are not likely to be displaced.

[0024] (3) In the wiring member of (2), it may be that a plurality of the bent portions are provided, and the second sheet is provided at positions on both sides of each of the plurality of bent portions. Thus, even if the first linear transmission member is pulled along the extending direction, the first linear transmission member and the first sheet are not likely to be displaced.

[0025] (4) In any of the wiring members of (1) to (3), it may be that the first linear transmission member includes a first transmission line main body and a first coating layer, the fusion layer is made of polyvinyl chloride, and the material constituting the first coating layer is a material different from polyvinyl chloride. Thus, the first linear transmission member having the first coating layer formed of a material different from polyvinyl chloride can be easily fixed to the polyvinyl chloride-based fusion layer by fusion.

[0026] (5) In any of the wiring members of (1) to (4), it may further include a second linear transmission member including a second transmission line body and a second coating layer, and the second coating layer is fused with the fusion layer so that the second linear transmission member is fixed to the first sheet. Thus, the first linear transmission member and the second linear transmission member are fixed to the same first sheet.

[0027] (6) In the wiring member of (5), it may be that the second linear transmission member is arranged on the first sheet so as to avoid the second sheet. Thus, overlap between the second sheet and the second linear transmission member can be suppressed.

[0028] (7) In the wiring member of (5) or (6), it may be that the second coating layer is made of a material different from the first coating layer of the first linear transmission member. Thus, the first linear transmission member and the second linear transmission member with different coating layer materials are fixed to the first sheet via the fusion layer.

[0029] (8) In any of the wiring members of (1) to (7), it may be that there is an interval where a plurality of first linear transmission members are arranged in parallel, and the fusion layer and the second sheet are fused between the plurality of first linear transmission members. Thus, a state is formed in which the plurality of first linear transmission members are separated by the second sheet, and contact between the plurality of first linear transmission members can be suppressed.

[0030] (9) In the wiring member of (8), it may be that one second sheet is arranged so as to cross the plurality of first linear transmission members, and the second sheet is fused to the first sheet at three or more positions including the position between the plurality of first linear transmission members and the positions on both sides thereof in one second sheet. Thus, the plurality of first linear transmission members are fixed to the first sheet by one second sheet.

[0031] (10) In any of the wiring members of (1) to (7), it may be that there is a collective part of a plurality of first linear transmission members, and the collective part is arranged inside a ring formed by the first sheet and the second sheet. Thus, the collective part of the plurality of first linear transmission members can be easily fixed to the first sheet.

[0032] (11) In any of the wiring members of (1) to (10), it may be that the second sheet includes a second sheet side fusion layer that is fused with the fusion layer of the first sheet. Thus, the first sheet and the second sheet can be fused with each other through the fusion layers of the first sheet and the second sheet, and the first sheet and the second sheet are firmly fixed.

[0033] [Details of the Embodiment of the Present Disclosure]

[0034] Hereinafter, while referring to the attached Figure 1An example of the wiring member of the present disclosure will be described. It should be noted that the present disclosure is not limited to these examples, and as indicated by the claims, it is intended to include all modifications within the meaning equivalent to the claims and the scope thereof.

[0035] [Embodiment 1]

[0036] Hereinafter, the wiring member of Embodiment 1 will be described. Figure 1 It is a schematic top view showing the wiring member of Embodiment 1. Figure 2 It is Figure 1 A partial enlarged view of. Figure 3 It is along Figure 2 A cross-sectional view taken along line III-III of. The portion indicated by the imaginary line in Figure 2 and Figure 3 is the fusion part WP.

[0037] The wiring member 10 includes a first sheet 20, a second sheet 30, and a first linear transmission member 40. Here, the wiring member 10 further includes a second linear transmission member 50. The first linear transmission member 40 and the second linear transmission member 50 are fixed to the first sheet 20. The fixing methods of the first linear transmission member 40 and the second linear transmission member 50 to the first sheet 20 are different.

[0038] The first sheet 20 includes a first sheet side fusion layer 22. The first sheet side fusion layer 22 includes a resin material (preferably a thermoplastic resin material). The resin material of the first sheet side fusion layer 22 softens and fuses to the fusion object. The type of this resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used.

[0039] The structure of the first sheet side fusion layer 22 is not particularly limited. For example, the first sheet side fusion layer 22 can be a sheet having a uniform solid cross-section (also referred to as a non-foamed sheet or a solid sheet, etc.). In addition, for example, it can also be considered that the first sheet side fusion layer 22 is a foamed sheet, etc. In addition, for example, it can also be considered that the first sheet side fusion layer 22 is a fibrous sheet such as a woven fabric, a textile fabric, or a non-woven fabric.

[0040] The first sheet 20 may have a single-layer structure composed of the first sheet side fusion layer 22. The first sheet 20 may also have a multi-layer structure. When the first sheet 20 has a multi-layer structure, preferably, the first sheet side fusion layer 22 appears on at least one main surface of the first sheet 20. Here, the first sheet 20 includes a first layer 22 and a second layer 24. The first layer 22 is the first sheet side fusion layer 22. The linear transmission members 40 and 50 are fixed to the first layer 22. One surface of the first layer 22 is set as one main surface of the first sheet 20.

[0041] The second layer 24 is formed of a material different from that of the first sheet-side fusion layer 22 or has a different structure. The second layer 24 enhances the functions of the first sheet-side fusion layer 22 or adds functions that the first sheet-side fusion layer 22 does not have to the first sheet 20. The material constituting the second layer 24 can also be a metal or the like in addition to the materials described for the first sheet-side fusion layer 22. The structure of the second layer 24 can also be any of the structures described for the first sheet-side fusion layer 22. One surface of the second layer 24 is provided as the other main surface of the first sheet 20.

[0042] The other surface of the first layer 22 and the other surface of the second layer 24 are in contact with each other, and the first layer 22 and the second layer 24 are fixed. The fixing method of the first layer 22 and the second layer 24 is not particularly limited, but it is preferably fixed by fusion or adhesion. For example, if at least one of the first layer 22 and the second layer 24 is a sheet having voids on the surface such as a fiber sheet or a foamed sheet, the resin material or the adhesive can enter the voids for fixing. Thus, the so-called anchoring effect is exerted, and the first layer 22 and the second layer 24 are firmly fixed.

[0043] Here, it is described that the first layer 22 is a solid resin sheet and the second layer 24 is a fiber sheet. Here, it is described that the first layer 22 and the second layer 24 are fused. That is, the resin of the first layer 22 enters between the fibers of the second layer 24 in a fluid state and then is cured. Thus, the state where the resin of the first layer 22 enters between the fibers of the second layer 24 is maintained, and the first layer 22 and the second layer 24 are firmly fixed.

[0044] The first layer 22 and the second layer 24 are formed to have the same size (same planar shape). The first layer 22 and the second layer 24 can also be formed such that one is larger than the other. The entire contact area of the first layer 22 and the second layer 24 can be fixed. Only a part of the contact area of the first layer 22 and the second layer 24 can also be fixed.

[0045] The first sheet 20 can be a flexible member. For example, the first layer 22 is a resin layer having a uniform solid cross-section made of a soft resin such as soft PVC, and the second layer 24 is a non-woven fabric made of PET or the like, and the first sheet 20 is provided as a flexible member. For example, the first sheet 20 can also have flexibility to follow the bending of the linear transmission members 40 and 50. That is, the wiring member 10 can also be capable of bending in the thickness direction (the bending with the crease along the main surface of the first sheet 20).

[0046] The second sheet 30 includes a second sheet side fusion layer 32. The material and structure of the second sheet side fusion layer 32 can adopt the material and structure described for the above-mentioned first sheet side fusion layer 22. The second sheet 30 can be a single-layer structure or a laminated structure formed by laminating multiple layers. When the second sheet 30 is a laminated structure, it is preferable that the second sheet side fusion layer 32 appears on one main surface of the second sheet 30.

[0047] The second sheet 30 can have the same structure as the first sheet 20 or a different structure. When the second sheet has the same structure as the first sheet 20, a part of the remaining slice when cutting out the first sheet 20 from a large-sized sheet member can be set as the second sheet. Thereby, an improvement in the yield rate of the sheet member can be achieved.

[0048] When the second sheet 30 has a different structure from the first sheet 20, the structure of the second sheet 30 is not particularly limited and can be appropriately set. For example, the thickness of the second sheet 30 and the thickness of the first sheet 20 can be the same, or the thickness of the second sheet 30 can be thicker than the thickness of the first sheet 20, or the thickness of the first sheet 20 can be thicker than the thickness of the second sheet 30.

[0049] Here, the second sheet 30 has a different structure from the first sheet 20. Here, the second sheet 30 is a single-layer structure with only the second sheet side fusion layer 32. Therefore, one main surface of the second sheet side fusion layer 32 constitutes one main surface of the second sheet 30, and the other main surface of the second sheet side fusion layer 32 constitutes the other main surface of the second sheet 30. The size of the second sheet 30 is not particularly limited, but the second sheet 30 is preferably formed smaller than the first sheet 20. The second sheet 30 is preferably smaller in size than the first sheet 20 in at least one of the extending direction and the width direction of the first sheet 20. Here, the second sheet 30 is smaller in size than the first sheet 20 in both the extending direction and the width direction of the first sheet 20.

[0050] The second sheet 30 is used to fix the first linear transmission member 40 to the first sheet 20. The second linear transmission member 50 is fixed to the first sheet 20 without using the second sheet 30. Details of the fixing method of the first linear transmission member 40 and the second linear transmission member 50 to the first sheet 20 will be described later.

[0051] The first linear transmission member 40 and the second linear transmission member 50 are respectively linear members for transmitting electricity, light, etc. The first sheet 20 is formed as a flat shape as a whole. By fixing the plurality of linear transmission members 40 and 50 to the first sheet 20, the wiring member 10 is maintained in a flat form.

[0052] It is assumed that the plurality of linear transmission members 40 and 50 are members that connect components in a vehicle to each other. For example, connectors C are provided at the ends of the linear transmission members 40 and 50. The linear transmission members 40 and 50 are connected to the components on the other side by connecting the connector C to the connector provided on the component on the other side. That is, the present wiring member 10 is used as a wiring member 10 that electrically (or in a manner capable of optical communication) connects various components to each other in a vehicle or the like. The connector C may also be fixed to the first sheet 20.

[0053] The paths of the plurality of linear transmission members 40 and 50 are set according to the positions of the components to be connected and the like. By fixing the plurality of linear transmission members 40 and 50 to the first sheet 20, the plurality of linear transmission members 40 and 50 are held in a state along the wiring paths corresponding to the positions of the components to be their respective connection destinations and the like. The plurality of linear transmission members 40 and 50 may also be fixed to the first sheet 20 in such a way that the branches are branched from the main line. The first sheet 20 may also be formed in a shape in which the portion for fixing the branch line branches from the portion for fixing the main line. Here, the plurality of linear transmission members 40 and 50 branch on the first sheet 20.

[0054] The linear transmission members 40 and 50 include a transmission line main body and a coating layer. The transmission line main body transmits electricity, light, or the like. The coating layer covers the transmission line main body. For example, the linear transmission members 40 and 50 may be general electric wires having a core wire and a coating layer around the core wire, or may be shielded wires, stranded wires, enameled wires, nichrome wires, optical fibers, or the like.

[0055] As the linear transmission members 40 and 50 for transmitting electricity, various signal lines and various power lines may be used. A part of the linear transmission members 40 and 50 for transmitting electricity may also be used as an antenna, a coil, or the like for transmitting or receiving signals or power to or from space.

[0056] In addition, the linear transmission members 40 and 50 may be single linear objects, or may be composites of a plurality of linear objects (stranded wires, cables obtained by aggregating a plurality of linear objects and covering them with an outer skin, etc.).

[0057] The first linear transmission member 40 includes a first transmission line main body 42 and a first coating layer 44. The first coating layer 44 is the outermost layer in the first linear transmission member 40. The second linear transmission member 50 includes a second transmission line main body 52 and a second coating layer 54. The second coating layer 54 is the outermost layer in the second linear transmission member 50.

[0058] The type of the resin material constituting the first coating layer 44 is different from the resin materials constituting the first sheet-side fusion layer 22, the second sheet-side fusion layer 32, and the second coating layer 54. The types of the resin materials constituting the first sheet-side fusion layer 22, the second sheet-side fusion layer 32, and the second coating layer 54 are the same.

[0059] For example, the resin materials constituting the first sheet-side fusion layer 22, the second sheet-side fusion layer 32, and the second coating layer 54 are PVC, and the material constituting the first coating layer 44 is a resin material different from PVC. In this case, the material constituting the first coating layer 44 only needs to be other than PVC, and is not particularly limited. For example, it can be polyolefins such as PE and PP, silicone resin, or fluororesin such as polytetrafluoroethylene. It should be noted that although the case where the resin material of the second coating layer 54 is PVC and the resin material of the first coating layer 44 is non-PVC is shown as above, it is not limited to this case. Of course, as long as the fixing strength of the first sheet 20 is different for the first coating layer 44 and the second coating layer 54. For example, of course, it also includes the case of using resin materials with different PVC contents in the second coating layer 54 and the first coating layer 44.

[0060] The resin material can also be halogen-free. Halogen-free means that it does not contain chlorine and bromine in halogens or contains them only in trace amounts. For example, in the standards of the IEC (International Electrotechnical Commission), the case where the content rate of each of chlorine and bromine is 900 ppm or less and the total content rate of chlorine and bromine is 1500 ppm or less is defined as halogen-free. The halogen-free linear transmission member is also called a halogen-free wire (for example, a halogen-free electric wire in the case of an electric wire), etc.

[0061] The combination of the materials constituting the first sheet-side fusion layer 22, the second sheet-side fusion layer 32, the first coating layer 44, and the second coating layer 54 is not limited to the above combination. For example, it can also be that the resin materials constituting the first sheet-side fusion layer 22, the second sheet-side fusion layer 32, and the second coating layer 54 are PE, and the material constituting the first coating layer 44 is a resin material different from PE.

[0062] The first linear transmission member 40 is fixed to the first sheet 20 by using the second sheet 30. Specifically, the first linear transmission member 40 is disposed between the first sheet 20 and the second sheet 30. A ring-shaped portion surrounding the periphery of the first linear transmission member 40 is formed by the first sheet 20 and the second sheet 30. The first linear transmission member 40 passes through the inner space of the ring-shaped portion. The first sheet 20 and the second sheet 30 are fixed via the fusion layers 22 and 32 in a direction intersecting the length direction of the first linear transmission member 40. The first sheet side fusion layer 22 and the second sheet side fusion layer 32 are fused on both sides of the first linear transmission member 40. Thus, the first linear transmission member 40 is fixed to the first sheet 20 by using the second sheet 30.

[0063] The first linear transmission member 40 is not directly joined to the first sheet 20 and the second sheet 30. Therefore, in the inner space of the ring-shaped portion, the first linear transmission member 40 can also move in the radial direction of the ring-shaped portion (the direction intersecting the extending direction of the first linear transmission member). In addition, the first linear transmission member 40 can move relative to the ring-shaped portion along the extending direction. Further, if the fusion state between the second sheet 30 and the first sheet 20 is eliminated, the first linear transmission member 40 becomes a state of being loosened from the first sheet 20.

[0064] The radial movement of the first linear transmission member 40 in the inner space of the ring-shaped portion can be suppressed by reducing the inner space and applying pressure from the ring-shaped portion to the first linear transmission member 40. To reduce the inner space, for example, it is performed by pressing the first linear transmission member 40 using the second sheet 30.

[0065] Bending portions 46 and 47 are provided where the first linear transmission member 40 is bent and arranged on the first sheet 20. The angle of the bending portion is not particularly limited and can be appropriately set. For example, if the angle at the straight portion is set to 180 degrees, the angle of the bending portion 46 is 150 degrees, and the angle of the bending portion 47 is 90 degrees. The angle of the bending portion is preferably any value between 90 degrees and 150 degrees.

[0066] Second pieces 30 are provided at positions on both sides of the bent portions 46 and 47 in the extending direction of the first linear transmission member 40. Thereby, it is possible to suppress the first linear transmission member 40 from moving significantly along the extending direction with respect to the annular portion. Here, the positions on both sides of the bent portions 46 and 47 are positions beside the bending start portion and the bending end portion. That is, the first linear transmission member 40 starts to bend at a position beside the other second piece 30 with respect to one second piece 30, and the first linear transmission member 40 ends bending at a position beside the one second piece 30 with respect to the other second piece 30. Regarding the positions on both sides of the bent portions 46 and 47, for example, a straight portion adjacent to the bent portions 46 and 47 can be cited, but as long as it is a structure in which the first linear transmission member 40 and the first piece 20 are not easily displaced, of course, it is not limited. For example, of course, it is sufficient that at least the second piece 30 provided on one side in the length direction of the first linear transmission member 40 at the bent portions 46 and 47 and the second piece 30 provided on the other side in the length direction of the first linear transmission member 40 at the bent portions 46 and 47 face different directions. Hereinafter, the bent portion 46 will be described in detail as an example.

[0067] That is, the first linear transmission member 40 extends along a first direction on one side of the bent portion 46 and extends along a second direction on the other side of the bent portion 46. The first direction and the second direction are directions that intersect each other. In addition, a second piece 30a is provided at a position on one side of the bent portion 46. In addition, a second piece 30b is provided at a position on the other side of the bent portion 46. If a portion of the first linear transmission member 40 located on one side of the bent portion 46 is pulled toward the end side along the first direction and the first linear transmission member 40 is about to move, the movement is suppressed by the interference between the first linear transmission member 40 and the second piece 30b. Similarly, if a portion of the first linear transmission member 40 located on the other side of the bent portion 46 is pulled toward the end side along the second direction and the first linear transmission member 40 is about to move, the movement is suppressed by the interference between the first linear transmission member 40 and the second piece 30a.

[0068] A plurality of bent portions 46 and 47 are provided on one first linear transmission member 40. Here, two bent portions are provided. Second pieces 30 are provided at positions on both sides of each of the plurality of bent portions 46 and 47. It should be noted that the path of the first linear transmission member 40 is set to bend in the same direction at the bent portions 46 and 47, but it can also be set to bend in the opposite direction.

[0069] In a state where the second sheet 30 is straight, the dimension of the second sheet 30 in the width direction of the first sheet 20 is set to be longer than the diameter of the first linear transmission member 40. Thus, on both sides of the first linear transmission member 40, the second sheet 30 can be fused with the first sheet 20. The interval between the two fusion portions WP of the first sheet 20 and the second sheet 30 located on both sides of the first linear transmission member 40 is not particularly limited and can be appropriately set. In addition, the size of the fusion portion WP of the first sheet 20 and the second sheet 30 in the width direction of the first sheet 20 is not particularly limited and can be appropriately set. If the interval between the two fusion portions WP and the size of the fusion portion WP become smaller, the dimension of the wiring member in the width direction can be reduced.

[0070] The second sheet 30 is provided on the first sheet 20 so as to cover a part of the first sheet 20 in the width direction. And, the second linear transmission member 50 is disposed on the first sheet 20 while avoiding the second sheet 30. The second linear transmission member 50 is disposed on the first sheet 20 at another part not covered by the second sheet 30.

[0071] In the second sheet 30, a part of the second sheet side fusion layer 32 faces the first sheet 20. The part of the second sheet side fusion layer 32 facing the first sheet 20 is fused with the first sheet side fusion layer 22.

[0072] When the first sheet side fusion layer 22 is fused to the second sheet side fusion layer 32 and the first coating layer 44 under the same conditions, the fusion strength between the first sheet side fusion layer 22 and the second sheet side fusion layer 32 is stronger than the fusion strength between the first sheet side fusion layer 22 and the first coating layer 44. Since the resin material constituting the first sheet side fusion layer 22 is a different type from the resin material constituting the first coating layer 44 and is the same type as the resin material constituting the second sheet side fusion layer 32, the fusion strength between the first sheet side fusion layer 22 and the second sheet side fusion layer 32 is stronger than the fusion strength between the first sheet side fusion layer 22 and the first coating layer 44. Here, the fusion strength in this specification can be evaluated, for example, using the results of tests performed separately by the same type of peel test (for example, each test of JIS K6854).

[0073] The second coating layer 54 of the second linear transmission member 50 is fused with the first sheet side fusion layer 22 and the second linear transmission member 50 is fixed to the first sheet 20. Since the resin material constituting the first sheet side fusion layer 22 is a different type from the resin material constituting the first coating layer 44 and is the same type as the resin material constituting the second coating layer 54, the fusion strength between the first sheet side fusion layer 22 and the second coating layer 54 is stronger than the fusion strength between the first sheet side fusion layer 22 and the first coating layer 44.

[0074] The means for forming such a fused state are not particularly limited. For example, various fusing means such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high-frequency fusion can be adopted. In addition, if a fused state is formed by these means, the linear transmission members 40 and 50 and the first sheet 20 are set in a state of being fused and fixed based on such means. Specifically, for example, when the linear transmission members 40 and 50 and the first sheet 20 are fused by ultrasonic fusion, the fusion portion WP becomes an ultrasonic fusion portion.

[0075] In Figure 2 In the example shown, the second sheet 30 is provided at a part along the extending direction of the first linear transmission member 40. The second sheets 30 are provided at a plurality of positions spaced apart along the extending direction of the first linear transmission member 40. And the second-sheet-side fusion layer 32 of each second sheet 30 is fused to the first-sheet-side fusion layer 22. Thus, the first linear transmission member 40 is fixed to the first sheet 20 at a plurality of positions spaced apart along the extending direction.

[0076] In each second sheet 30, when the wiring member 10 is observed along the extending direction as Figure 2 shown, a part of the second-sheet-side fusion layer 32 along the extending direction of the first linear transmission member 40 is fused to the first-sheet-side fusion layer 22. That is, each second sheet 30 is not integrally fused to the first sheet 20 along the extending direction of the first linear transmission member 40. In each second sheet 30, there is a part that is not fused to the first-sheet-side fusion layer 22 in a part along the extending direction of the first linear transmission member 40.

[0077] However, the second sheets 30 may also be integrally and continuously provided along the extending direction of the first linear transmission member 40. In this case, the second sheets 30 may be integrally and continuously fused to the first sheet 20 along the extending direction, or may be fused to the first sheet 20 at a plurality of positions spaced apart along the extending direction.

[0078] In Figure 2 the example shown, the second linear transmission member 50 is fused to the first sheet 20 at a plurality of positions spaced apart along the extending direction. The second linear transmission member 50 may also be integrally and continuously fixed to the first sheet 20 along the extending direction.

[0079] In Figure 2 the example shown, the first linear transmission member 40 and the second linear transmission member 50 are fused to the first sheet 20 at the same position along the extending direction in a parallel section. However, the first linear transmission member 40 and the second linear transmission member 50 may also be fused to the first sheet 20 at different positions along the extending direction in a parallel section.

[0080] In Figure 2In the example shown, one first linear transmission member 40 is provided. A plurality of first linear transmission members 40 may also be provided. It is sufficient to provide at least one first linear transmission member 40. The case where a plurality of first linear transmission members 40 are provided will be described in detail in Embodiment 2.

[0081] The second linear transmission member 50 includes a plurality of members. The second linear transmission member 50 may also include only one member. When the wiring member 10 includes the second linear transmission member 50, it is sufficient to include at least one member. The second linear transmission member 50 may also be omitted.

[0082] In Figure 2 In the example shown, the number of second linear transmission members 50 is larger than the number of first linear transmission members 40. The number of second linear transmission members 50 may also be the same as or smaller than the number of first linear transmission members 40. When the linear transmission members 40 and 50 are classified by resin material, that is, when the first linear transmission member 40 is further subdivided by resin material in addition to the classification of the first linear transmission member 40 and the second linear transmission member 50, among all types of linear transmission members 40 and 50, it is preferably that the number of second linear transmission members 50 is the largest. Thereby, the number of first linear transmission members 40 fixed to the first sheet 20 via the second sheet 30 can be suppressed to be small, and the manufacture of the wiring member 10 becomes easy.

[0083] In Figure 2 In the example shown, the first linear transmission member 40 is located on the outermost side along the juxtaposition direction of the plurality of linear transmission members 40 and 50. The first linear transmission member 40 is located outside the plurality of second linear transmission members 50. The first linear transmission member 40 may also be located in the middle along the juxtaposition direction of the plurality of linear transmission members 40 and 50. The first linear transmission member 40 may also be located between the plurality of second linear transmission members 50.

[0084] In Figure 2 In the example shown, a plurality of linear transmission members 40 and 50 having the same diameter are provided on one first sheet 20. However, the diameters of the plurality of linear transmission members 40 and 50 may be appropriately set, and linear transmission members 40 and 50 having different diameters may also be provided on the same first sheet 20.

[0085] For example, as Figure 4 shown in the wiring member 110, the diameter of the first linear transmission member 140 may also be larger than the diameter of at least a part of the second linear transmission members 50. In Figure 4In the example shown, the first linear transmission member 140 is a cable such as a USB cable (also referred to as a multi-core wire), and the second linear transmission member 50 is a single-core wire. Thus, the diameter of the first linear transmission member 140 is larger than the diameter of at least a part of the second linear transmission member 50.

[0086] Figure 4 The cable 140 shown includes four covered wires 141a, 141b, 141c, and 141d. Two of the four covered wires 141a, 141b, 141c, and 141d, namely 141a and 141b, are gathered by an outer sheath 143 to form a cable 141e. The two covered wires 141c, 141d and one cable 141e are gathered by an outer sheath 144 to form the cable 140. In the cable 140, the outer sheath 144 is the first covering layer 144. In the cable 140, the first transmission line body is the core wires of the respective covered wires 141a, 141b, 141c, and 141d.

[0087] Alternatively, the diameter of the first linear transmission member 40 is larger than the diameter of at least a part of the second linear transmission member 50 by the first linear transmission member 40 having a shielding layer. A linear transmission member having a shielding layer is also referred to as a shielded wire, coaxial cable, etc. In the first linear transmission member 40, the shielding layer is provided between the first transmission line body 42 and the first covering layer 44. Usually, an insulating layer is provided between the shielding layer and the first transmission line body 42. A shielding layer may also be provided in the cable 140.

[0088] <Effects of Embodiment 1, etc.>

[0089] According to the wiring members 10, 110 configured as described above, the first sheet 20 and the second sheet 30 are fixed via the fusion layer 22 in a direction intersecting the length direction of the first linear transmission members 40, 140, and thus are maintained in a state where the first linear transmission members 40, 140 are disposed between the first sheet 20 and the second sheet 30. Thereby, the linear transmission member can be fixed to the first sheet 20 via the fusion layer 22 regardless of the type of the linear transmission member. In addition, the second sheet 30 includes a second sheet side fusion layer 32 that fuses with the first sheet side fusion layer 22 of the first sheet 20. Thus, the first sheet 20 and the second sheet 30 can be fused with each other by the fusion layers 22, 32 of the first sheet 20 and the second sheet 30, and the first sheet 20 and the second sheet 30 are firmly fixed.

[0090] In addition, since the second sheet 30 is provided at positions on both sides of the bent portions 46, 47 along the extending direction of the first linear transmission members 40, 140, even if the first linear transmission members 40, 140 are pulled along the extending direction, the first linear transmission members 40, 140 and the first sheet 20 are not likely to be displaced.

[0091] In addition, since the second sheets 30 are provided at positions on both sides of each of the plurality of bent portions 46, 47, even if the first linear transmission members 40, 140 are pulled along the extending direction, the first linear transmission members 40, 140 and the first sheet 20 are not likely to be displaced in position.

[0092] In addition, the first sheet side fusion layer 22 is made of polyvinyl chloride, and the materials constituting the first coating layers 44, 144 are different from polyvinyl chloride. Therefore, the first linear transmission members 40, 140 having the first coating layers 44, 144 formed of materials different from polyvinyl chloride can be easily fusion-fixed to the polyvinyl chloride-based first sheet 20 via the second sheets 30.

[0093] In addition, since the second coating layer 54 is fused with the first sheet side fusion layer 22 and the second linear transmission member 50 is fixed to the first sheet 20, the first linear transmission members 40, 140 and the second linear transmission member 50 are fixed to the same first sheet 20. In addition, since the second coating layer 54 is made of a material different from that of the first coating layer 44, the first linear transmission member 40 and the second linear transmission member 50 having different coating layer materials are fixed to the first sheet 20 via the fusion layer 22.

[0094] In addition, since the second linear transmission member 50 is arranged on the first sheet 20 so as to avoid the second sheet 30, the overlap between the second sheet 30 and the second linear transmission member 50 can be suppressed.

[0095] [Embodiment 2]

[0096] The wiring member of Embodiment 2 will be described. Figure 5 FIG. is a cross-sectional view showing the wiring member of Embodiment 2. It should be noted that in the description of the present embodiment, the same reference numerals are given to the same components as those described so far, and the description thereof is omitted.

[0097] The wiring member 210 is different from the above-described wiring members 10, 110 in that a plurality of first linear transmission members 40 are provided. The number of the first linear transmission members 40 is not particularly limited and can be appropriately set. In Figure 5 the example shown, two first linear transmission members 40 are provided, but three or more may be provided.

[0098] In this example, a section where a plurality of first linear transmission members 40 are arranged in parallel will be described. In addition, in this example, a plurality of first linear transmission members 40 are branched (that is, a plurality of first linear transmission members 40 are parallel in a part of the section and not parallel in another part of the section). However, a section where a plurality of first linear transmission members 40 are arranged in parallel may not be provided. In addition, a plurality of first linear transmission members 40 may be parallel throughout.

[0099] Between a plurality of first linear transmission members 40 in a parallel section, a first sheet-side fusion layer 22 and a second sheet-side fusion layer 32 are fused. Thereby, it is possible to suppress arranging a plurality of first linear transmission members 40 in one annular portion formed by the first sheet 20 and the second sheet 30. That is, a plurality of annular portions formed by the first sheet 20 and the second sheet 30 are provided. One first linear transmission member 40 passes through each of the plurality of annular portions. At this time, in Figure 5 the example shown, a plurality of first linear transmission members 40 are held by one second sheet 30.

[0100] More specifically, one second sheet is provided so as to cross a plurality of first linear transmission members 40. The second sheet-side fusion layer 32 is fused to the first sheet-side fusion layer 22 at three or more positions in one second sheet including positions between the plurality of first linear transmission members 40 and positions on both sides thereof. Regarding the number of fusion portions WP of the first sheet 20 and the second sheet 30 along the width direction of the first sheet, the number obtained by adding 1 to the number of first linear transmission members 40 may be set, and of course, a larger number may also be set.

[0101] Alternatively, a plurality of first linear transmission members 40 may be held by independent second sheets 30. In this case, the number of fusion portions WP of the first sheet 20 and the second sheet 30 along the width direction of the first sheet 20 needs to be twice the number of first linear transmission members 40. In addition, between a plurality of first linear transmission members 40 in a parallel section, the first sheet-side fusion layer 22 and the second sheet-side fusion layer 32 may not be fused. In this case, a plurality of first linear transmission members are arranged in one annular portion. Regarding the case of arranging a plurality of first linear transmission members in one annular portion, use Figure 6 will be described in detail. Figure 6 is a cross-sectional view showing a modified example of the wiring member 210 of Embodiment 2.

[0102] In Figure 6 the wiring member 310 shown, it is different from the above-described wiring member 210 in that a plurality of first linear transmission members 340 are arranged in the inner space of one annular portion. In the wiring member 310, an assembly portion 48 of a plurality of first linear transmission members 340 is provided. The assembly portion 48 is arranged in the inner space of one annular portion. Thereby, the assembly portion 48 can be easily fixed to the first sheet 20.

[0103] A plurality of first linear transmission members 340 may include linear transmission members that are not easily fused to the first sheet 20, such as the first linear transmission members 40 and 140 described above. The plurality of first linear transmission members 340 may also include linear transmission members that are easily fused to the first sheet 20, such as the second linear transmission member 50 described above. The collective portion 48 is the portion where the plurality of first linear transmission members 340 are collected, and thus, like the first linear transmission members 40 and 140 described above, it is a portion that is less likely to be fused to the first sheet 20 than the single second linear transmission member 50.

[0104] It is sufficient that the collective portion 48 is provided in at least a part of the paths of the plurality of first linear transmission members 340 on the first sheet 20. Either one or both of the end portions of the collective portion 48 may be located outside the first sheet 20. That is, the plurality of first linear transmission members 340 constituting the collective portion 48 may extend outward from the outer edge portion of the first sheet 20 while maintaining the state of the collective portion 48. Either one or both of the end portions of the collective portion 48 may also be located on the first sheet.

[0105] The structure of the plurality of first linear transmission members 340 constituting the collective portion 48 may remain unchanged from one end portion to the other end portion of the collective portion 48. The structure of the plurality of first linear transmission members 340 constituting the collective portion 48 may also change midway from one end portion of the collective portion 48 to the other end portion. A part of the plurality of first linear transmission members 340 constituting the collective portion 48 may be detached from the collective portion 48 midway from one end portion of the collective portion 48 to the other end portion. Another first linear transmission member 340 may also newly converge to the collective portion 48 midway from one end portion of the collective portion 48 to the other end portion. Either one or both of the detachment of these first linear transmission members 340 from the collective portion 48 and the convergence of the first linear transmission members 340 to the collective portion 48 may occur on the first sheet 20.

[0106] In the collective portion 48, the plurality of first linear transmission members 340 are not collected by a collecting member other than the second sheet 30. In the collective portion 48, the plurality of first linear transmission members 340 may also be collected by a collecting member other than the second sheet 30. Any member may be used as this collecting member. For example, the collecting member may be a bundling member such as an adhesive tape, or a pipe member such as a bellows. The collecting member is preferably a member that is continuously extruded and formed around the plurality of first linear transmission members 340, such as the outer skin 143. The collecting member may be continuously provided along the extending direction of the collective portion 48, or may be provided at a plurality of positions with an interval therebetween. When the collective portion 48 is collected by the collecting member, the second sheet 30 may cover the portion of the collective portion 48 collected by the collecting member, or may cover the portion not collected by the collecting member.

[0107] It is possible that the first coating layers 44 of all the first linear transmission members 40 are made of the same type of resin material. For example, it is possible that the resin material constituting the first coating layers 44 of all the first linear transmission members 40 is PE. Additionally, it is also possible that the resin material of the first coating layer 44 of a part of the first linear transmission members 40 and the resin material of the first coating layer 44 of another part of the first linear transmission members 40 are of different types. For example, it is also possible to provide first linear transmission members 40 with first coating layers 44 made of PE and first linear transmission members 40 with first coating layers 44 made of fluororesin.

[0108] In Figure 5 the example shown, in the parallel section, the plurality of first linear transmission members 40 are parallel at adjacent positions without sandwiching the second linear transmission member 50 therebetween. In this case, it is preferable that, as in the example shown in Figure 5 a plurality of first linear transmission members 40 are held by one second sheet 30.

[0109] In the parallel section, the plurality of first linear transmission members 40 may also be parallel while sandwiching the second linear transmission member 50 therebetween. In this case, it is preferable that the plurality of first linear transmission members 40 are held by independent second sheets 30. It is also possible that two first linear transmission members 40 are respectively located on the outermost sides along both sides of the juxtaposition direction of the plurality of linear transmission members 40, 50.

[0110] <Effects of Embodiment 2, etc.>

[0111] With the wiring member 210 configured as described above, the same effects as those of the wiring members 10, 110 of Embodiment 1 can also be obtained.

[0112] In addition, according to the wiring member 210, since the first sheet side fusion layer 22 and the second sheet side fusion layer 32 are fused between the plurality of first linear transmission members 40, it becomes a state where the plurality of first linear transmission members 40 are separated by the second sheet 30, and contact between the plurality of first linear transmission members 40 can be suppressed.

[0113] In addition, the second sheet side fusion layer 32 is fused to the first sheet side fusion layer 22 at three or more positions including the position between the plurality of first linear transmission members 40 and the positions on both sides thereof in one second sheet 30. Thus, the plurality of first linear transmission members 40 are fixed to the first sheet 20 by one second sheet 30.

[0114] [Modification Example]

[0115] In addition, so far, it has been described that the bending portions 46 and 47 are provided on the first linear transmission member 40, and the first sheet 20 and the second sheet 30 are fused at the positions on both sides of the bending portions 46 and 47, but this is not an essential structure. The bending portions 46 and 47 may not be provided on the first linear transmission member 40. Further, even when the bending portions 46 and 47 are provided on the first linear transmission member 40, the number thereof is not particularly limited, and may be one, or may be three or more. Further, even when the bending portions 46 and 47 are provided on the first linear transmission member 40, the first sheet 20 and the second sheet 30 may not be fused at the positions on both sides of the bending portions 46 and 47.

[0116] So far, it has been described that the second sheet 30 is provided on the first sheet 20 so as to cover a part of the first sheet 20 in the width direction, but this is not an essential structure. The second sheet 30 may also be provided on the first sheet 20 so as to cover the entire first sheet 20 in the width direction. In this case, the second linear transmission member 50 is disposed on the first sheet 20 at a portion covered by the second sheet 30.

[0117] Further, even when the second sheet 30 is provided on the first sheet 20 so as to cover a part of the first sheet 20 in the width direction, the second linear transmission member 50 may be disposed on the first sheet 20 at a portion covered by the second sheet 30.

[0118] When the second linear transmission member 50 is disposed on the first sheet 20 at a portion covered by the second sheet 30, the second linear transmission member 50 may be clamped by the first sheet 20 and the second sheet 30 in the same manner as the first linear transmission member 40. In this case, preferably, the second sheet 30 and the first sheet 20 are fused between the first linear transmission member 40 and the second linear transmission member 50, and the first linear transmission member 40 and the second linear transmission member 50 are separated. When the second linear transmission member 50 is disposed on the first sheet 20 at a portion covered by the second sheet 30, the second sheet 30 may be clamped by the first sheet 20 and the second linear transmission member 50. In this case, the fusion portion WP between the second linear transmission member 50 and the first sheet 20 is preferably provided at a position not overlapping the second sheet 30 along the extending direction of the second linear transmission member 50.

[0119] So far, it has been described that a part of the second sheet side fusion layer 32 along the extending direction of the first linear transmission members 40 and 140 is fused with the first sheet side fusion layer 22, but this is not an essential structure. It may also be that the entire second sheet side fusion layer 32 along the extending direction of the first linear transmission members 40 and 140 is fused with the first sheet side fusion layer 22.

[0120] In addition, so far, the second sheet 30 has been described as including the second side fusion layer 32, but this is not an essential structure. The second sheet 30 may not include the second side fusion layer 32. The second sheet 30 only needs to include a layer on the surface that can fuse with the first side fusion layer 22.

[0121] The color of the second sheet 30 (the color of the second side fusion layer 32) and the colors of the first coating layers 44 and 144 may be the same or different. If the color of the second sheet 30 (the color of the second side fusion layer 32) is different from the colors of the first coating layers 44 and 144, then when the second sheet 30 is partially disposed on the first linear transmission members 40 and 140, the position of the second sheet 30 is easily recognizable. Thereby, it is possible to prevent the fusion machine from colliding with portions of the first linear transmission members 40 and 140 where the second sheet 30 is not provided.

[0122] It should be noted that the respective structures described in the above-described embodiments and respective modification examples can be appropriately combined as long as they do not contradict each other.
