[0015] Figure 3 It is a cross-sectional view showing a modified example of the wiring member. DETAILED DESCRIPTION
[0016] [Description of Embodiments of the Present Disclosure]
[0017] First, embodiments of the present disclosure will be described.
[0018] The wiring member of the present disclosure is as follows.
[0019] (1) A wiring member comprising: a sheet; a plurality of first linear transmission members arranged on the sheet; and a second linear transmission member intersecting at least two of the plurality of first linear transmission members, wherein a first intersection section is defined as a first intersection section, wherein two intersection sections located at opposite ends of the second linear transmission member in the longitudinal direction of the at least two intersection sections where each of the at least two first linear transmission members intersects with the second linear transmission member are connected by the second linear transmission member. The second linear transmission member is fixed to the sheet at a plurality of locations spaced apart along the longitudinal direction. The length of the first intersection section is greater than the largest fixed interval of the fixed intervals of the second linear transmission member, excluding at least the first intersection section. In the first intersection section, the second linear transmission member is located closer to the sheet than the at least two first linear transmission members. Thus, in the first intersection section, the second linear transmission member is less likely to lift from the sheet.
[0020] (2) In the wiring member of (1), the portion where the second linear transmission member is fixed to the sheet may be provided in the first intersection section. This makes it more difficult for the second linear transmission member to lift off from the sheet in the first intersection section.
[0021] (3) In the wiring member of (1), the second linear transmission member may not be fixed to the sheet in the first intersection section. Even in this case, the second linear transmission member is not easily lifted from the sheet by being pressed by the plurality of first linear transmission members.
[0022] (4) In any one of the wiring members of (1) to (3), at least one of the plurality of first linear transmission members may be a thicker linear transmission member than the second linear transmission member. Thus, the second linear transmission member is pressed by the thicker linear transmission member, making it less likely for the second linear transmission member to lift off the sheet.
[0023] (5) In any one of the wiring members of (1) to (4), the coating layers of the plurality of first linear transmission members and the second linear transmission members may be fused to the sheet. Thus, the plurality of first linear transmission members and the second linear transmission members can be easily fixed to the sheet.
[0024] (6) In any one of the wiring members of (1) to (5), at least one of the plurality of first linear transmission members may intersect with the plurality of second linear transmission members, and in each of the at least one first linear transmission member, a section where the intersection portions located at both ends of the first linear transmission member in the longitudinal direction are connected by the first linear transmission member is defined as a second intersection section. The at least one first linear transmission member is fixed to the sheet at a plurality of locations spaced apart along the longitudinal direction of the first linear transmission member, and the length of the second intersection section is smaller than the largest fixed interval of the fixed intervals of the first linear transmission member, excluding at least the second intersection section. Thus, the fixed intervals of the first linear transmission members in the second intersection section can be prevented from becoming larger, and the first linear transmission members are less likely to warp from the sheet.
[0025] (7) In the wiring member of (6), the fixed interval of the first linear transmission member including the second intersection section may be smaller than the largest fixed interval excluding the second intersection section. This can prevent the fixed interval of the first linear transmission member from increasing in the second intersection section, and the first linear transmission member is less likely to warp from the sheet.
[0026] (8) In any one of the wiring members of (1) to (7), the at least two first linear transmission members may be arranged in parallel in a parallel section, and the second linear transmission member may intersect with the at least two first linear transmission members in the parallel section. This can reduce the length of the first intersecting section.
[0027] [Details of the embodiments of the present disclosure]
[0028] Below, with reference to the attached Figure 1 While describing specific examples of the wiring member of the present disclosure, it should be noted 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.
[0029] [Implementation Method 1]
[0030] Hereinafter, the wiring member according to the first embodiment will be described. Figure 1 This is a plan view showing wiring member 10 according to the first embodiment. Figure 2 It is along Figure 1 The cross-sectional view when the II-II line is cut. Figure 1 and Figure 2 The portion indicated by the imaginary line in FIG. 1 is the fixing portion FP.
[0031] The wiring member 10 includes a sheet 20 and a plurality of linear transmission members 30. The plurality of linear transmission members 30 are fixed to the sheet 20. The sheet 20 is formed into a flat shape as a whole. The plurality of linear transmission members 30 are fixed to the sheet 20, so that the wiring member 10 is maintained in a flat shape.
[0032] The sheet 20 is not particularly limited in material or structure, as long as it can secure the plurality of linear transmission members 30. Regarding the material constituting the sheet 20, the sheet 20 is herein formed of a resin material. Materials other than resin, such as metals and inorganic materials, may also be used to constitute the sheet 20. Regarding the structure of the sheet 20, the sheet 20 is herein shown to have a two-layer structure. The sheet 20 may also have a single-layer structure or a multi-layer structure of three or more layers.
[0033] Sheet 20 includes a first layer 22 and a second layer 24. First layer 22 is a fusion layer. Linear transmission member 30 is fused and fixed to the fusion layer. The fusion layer comprises a resin material (preferably a thermoplastic resin material). The resin material of the fusion layer softens and fuses to the fusion partner. The type of resin material is not particularly limited; polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and the like can be used.
[0034] The structure of the fusion layer is not particularly limited. For example, the fusion layer can be a sheet having a uniform solid cross-section (also referred to as a non-foamed sheet or solid sheet). Alternatively, for example, the fusion layer can be a foamed sheet. Alternatively, for example, the fusion layer can be a sheet of fiber material such as woven fabric, woven fabric, or non-woven fabric. One surface of the first layer 22 is defined as one principal surface of the sheet 20.
[0035] The second layer 24 is formed of a different material than the fusion layer or has a different structure. The second layer 24 enhances the functionality of the fusion layer or adds functionality not possessed by the fusion layer to the sheet 20. In addition to the materials described above for the fusion layer, the second layer 24 may also be made of metals, inorganic materials, and the like. The structure of the second layer 24 may be any of the structures described above for the fusion layer. One surface of the second layer 24 serves as the other principal surface of the sheet 20.
[0036] The first and second layers 22, 24 are fixed together when the other surface of the first layer 22 and the other surface of the second layer 24 are in contact. The method for fixing the first and second layers 22, 24 is not particularly limited, but preferably, they are fixed together by fusion or bonding. For example, if at least one of the first and second layers 22, 24 is a sheet with voids in its surface, such as a fiber sheet or a foam sheet, the resin material or adhesive can enter the voids and secure the first and second layers. This creates a so-called anchoring effect, firmly securing the first and second layers 22, 24.
[0037] Here, the first layer 22 is described as a solid sheet made of resin, and the second layer 24 is described as a sheet of fiber material. The first layer 22 and the second layer 24 are fused together. In other words, the resin in the first layer 22, while still fluid, enters between the fibers of the second layer 24 and then solidifies. This maintains the resin in the first layer 22 between the fibers of the second layer 24, firmly securing the first and second layers 22 and 24.
[0038] The first layer 22 and the second layer 24 are formed to be the same size (the same planar shape). Alternatively, one of the first layer 22 and the second layer 24 may be formed larger than the other. The entire contact area between the first layer 22 and the second layer 24 may be fixed. Alternatively, a portion of the contact area between the first layer 22 and the second layer 24 may be fixed.
[0039] The sheet 20 can be a flexible member. For example, the first layer 22 can be a solid sheet made of a soft resin such as soft PVC, and the second layer 24 can be a nonwoven fabric made of PET. The sheet 20 can be a flexible member. For example, the sheet 20 can have flexibility to follow the bending of the linear transmission member 30. The wiring member 10 can bend in the thickness direction (curve with the fold along the main surface of the sheet 20).
[0040] The plurality of linear transmission members 30 are linear members that transmit electricity, light, or the like. It is conceivable that the plurality of linear transmission members 30 are members that connect components within a vehicle. For example, a connector C is provided at the end of the linear transmission member 30. This connector C is connected to a connector provided on a counterpart component, thereby connecting the linear transmission member 30 to the counterpart component. In other words, the wiring member 10 is used as a wiring member 10 that electrically (or optically) connects various components within a vehicle, etc. The connector C may also be fixed to the sheet 20.
[0041] The paths of the multiple linear transmission members 30 are determined based on, for example, the locations of the components to be connected. By attaching the multiple linear transmission members 30 to the sheet 20, the multiple linear transmission members 30 are maintained along routing paths corresponding to, for example, the locations of the components to be connected. The paths of the multiple linear transmission members 30 can be a combination of straight and curved paths. The sheet 20 can also be configured with a combination of straight and curved paths. The multiple linear transmission members 30 can be attached to the sheet 20 in a manner that branches partially. The sheet 20 can also be formed in a branched shape. In this case, the multiple linear transmission members 30 bend on the sheet 20. Alternatively, the multiple linear transmission members 30 can branch on the sheet 20.
[0042] The linear transmission member 30 includes a transmission line body 31 and a coating 32. The transmission line body 31 is a transmission path for transmitting electricity or light. For example, if the linear transmission member 30 is an electric wire, the transmission line body 31 is a conductor core wire. The conductor core wire is composed of one or more wires. The wires are formed from materials such as copper, copper alloys, aluminum, and aluminum alloys. Alternatively, if the linear transmission member 30 is an optical fiber, the transmission line body 31 is composed of the core and cladding. The coating 32 is a layer covering the transmission line body 31. The resin material constituting the coating 32 is not particularly limited and can be selected as appropriate. For example, the linear transmission member 30 can be a conventional electric wire having a core wire and a coating surrounding the core wire, or it can be a shielded wire, stranded wire, enameled wire, nichrome wire, or optical fiber.
[0043] The power transmission linear member 30 may be various signal lines or power lines. A portion of the power transmission linear member 30 may be used as an antenna or coil for transmitting or receiving signals or power into or from space.
[0044] 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 a single transmission path. The linear transmission member 30 may also be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A single-core wire is a linear transmission member 30 with multiple transmission paths. Multi-core wires may be, for example, twisted wires or cables formed by combining multiple linear objects and covering them with a sheath.
[0045] Here, the linear transmission member 30 is fixed to the sheet 20 by fusion. In this case, the outermost layer of the linear transmission member 30 and the fusion layer are fused. The outermost layer of the linear transmission member 30 is the coating layer 32. The coating layer 32 is made of a material capable of fusing to the fusion layer. The resin material constituting the coating layer 32 is the same 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 32 may be PVC or polyolefin. However, the method of fixing the linear transmission member 30 to the sheet 20 is not limited to fusion. Fixation methods other than fusion will be described in detail in the modified examples described below.
[0046] The linear transmission member 30 is fixed to the sheet 20 at multiple locations spaced apart along the extending direction. Multiple fixing portions FP between the sheet 20 and the linear transmission member 30 are provided at intervals along the extending direction of the linear transmission member 30. The intervals between the fixing portions FP are not particularly limited and can be set as appropriate.
[0047] Here, eight linear transmission members 30 are included. These eight linear transmission members 30 are divided into two linear transmission members 30A, four linear transmission members 30B, and two linear transmission members 30C. One end of each linear transmission member 30A and 30B is connected to the same connector C. The other ends of each linear transmission member 30A and 30B are connected to different connectors C. The linear transmission members 30A and 30B branch off midway between one end and the other. In the parallel section where the linear transmission members 30A and 30B are arranged, the six linear transmission members 30 are arranged in parallel. The linear transmission members 30A and 30B are an example of a plurality of first linear transmission members arranged in parallel in at least a portion of the parallel section on the sheet 20.
[0048] The linear transmission member 30C intersects each of the linear transmission members 30A and 30B in an intersection region A1. The intersection region A1 is located in the parallel section where the linear transmission members 30A and 30B are aligned. The linear transmission member 30C is an example of a second linear transmission member that intersects with the plurality of first linear transmission members in the parallel section. Both ends of the linear transmission member 30C are connected to connectors C that are different from the connectors C connected to the linear transmission members 30A and 30B. At least one end of the linear transmission member 30C may also be connected to the same connector C as the connectors C connected to the linear transmission members 30A and 30B.
[0049] In this specification, the portion where the two linear transmission members 30 intersect on the sheet 20 is referred to as the intersection 40. Hereinafter, the portion where the two linear transmission members 30A and 30C intersect is sometimes referred to as the intersection 40AC. The portion where the two linear transmission members 30B and 30C intersect is sometimes referred to as the intersection 40BC. Furthermore, of the two linear transmission members 30 constituting a single intersection 40, the linear transmission member 30 located on the sheet 20 side is sometimes referred to as the lower linear transmission member, and the other linear transmission member 30 is sometimes referred to as the upper linear transmission member.
[0050] exist Figure 1 In the example shown, eight of the twelve intersections 40 in intersection area A1 are intersections 40AC, and four are intersections 40BC. In intersection area A1, linear transmission members 30A, 30B, and linear transmission member 30C intersect for branching. On either side of intersection area A1, linear transmission members 30A, 30B, and linear transmission member 30C extend in different directions. It should be noted that linear transmission members 30A, 30B, and linear transmission member 30C can also run parallel to each other on either side of intersection area A1.
[0051] The section where a linear transmission member 30 intersects with one or more other linear transmission members 30 in an intersection area A1 is defined as an intersection section. The intersection section where a linear transmission member 30 intersects with multiple other linear transmission members 30 in an intersection area A1 is defined as follows. Multiple intersections 40 are formed between the linear transmission member 30 and the multiple other linear transmission members 30. The two intersections 40 located at the outermost sides (ends) of the linear transmission member 30 along its longitudinal direction are defined as large outer intersections. The section where these two large outer intersections are connected by the linear transmission member 30 is defined as the intersection section where the linear transmission member 30 intersects with multiple other linear transmission members 30 in an intersection area A1. The length of the intersection section is defined as the length of the central axis of the linear transmission member 30 extending between the outer edges of the two large outer intersections.
[0052] For example, in the intersection region A1, one linear transmission member 30C intersects with six linear transmission members 30A and 30B to form six intersections 40AC and 40BC. Figure 1As shown, the largest outer intersections among the six intersections 40AC and 40BC are intersections 40AC1 and 40BC1. In a single linear transmission member 30C, the section connecting the two largest outer intersections 40AC1 and 40BC1 by the single linear transmission member 30C is defined as the intersection section. Here, the intersection section of the linear transmission member 30C is an example of a first intersection section. When multiple first linear transmission members 30A and 30B are provided and the multiple first linear transmission members 30A and 30B are not arranged parallel in the intersection area A1, the dimension connecting the two intersections located at the longitudinal ends of each second linear transmission member 30C by the second linear transmission member 30C is defined as the first intersection section.
[0053] Similarly, the intersection section of the linear transmission member 30A is a section where two intersection portions 40AC intersecting the two linear transmission members 30C are connected by the linear transmission member 30A. The intersection section of the linear transmission member 30A is an example of a second intersection section. The intersection section of the linear transmission member 30B is a section where two intersection portions 40BC intersecting the two linear transmission members 30C are connected by the linear transmission member 30B. The intersection section of the linear transmission member 30B is an example of a second intersection section. When the plurality of first linear transmission members 30A and 30B are not parallel in the intersection area A1, the dimension of connecting the two intersection portions located at both ends of the length direction of each first linear transmission member 30A and 30B by the first linear transmission members 30A and 30B is set as the second intersection section. The length dimension of the intersection section (second intersection section) of the linear transmission members 30A and 30B is Figure 1 The length dimension of the intersection section (first intersection section) of the linear transmission member 30C is Figure 1 、 Figure 2 Dimension D2 in.
[0054] The maximum fixed interval is the maximum fixed interval in the straight section of the fixed interval of the linear transmission member 30, excluding the intersection section. When the sheet 20 and the linear transmission member 30 are fused and fixed, the fixed interval is the dimension between the inner edges of the two fixing parts FP. The fixed interval is the length dimension of the portion of the linear transmission member 30 that is not fixed to the sheet 20 between the two fixing parts FP. For example, the maximum fixed interval of the linear transmission member 30A is Figure 1 In addition, for example, the maximum fixed interval of the linear transmission member 30B is Figure 1 In addition, for example, the maximum fixed interval of the linear transmission member 30C is Figure 1 、 Figure 2 Size D5 in size.
[0055] The length dimension of the intersection section (first intersection section) of the linear transmission member 30C is larger than the maximum fixed interval of the linear transmission member 30C. Figure 1 、 Figure 2 As shown, dimension D2 is larger than dimension D5. It should be noted that when there are multiple second linear transmission members 30C, when comparing the multiple second linear transmission members 30C, there may be cases where at least one of the length of the first intersection section and the maximum fixed interval differs. In this case, the length of the first intersection section in each second linear transmission member 30C only needs to be larger than the maximum fixed interval. The length of the first intersection section of a second linear transmission member 30C may be less than the maximum fixed interval of another second linear transmission member 30C. Alternatively, a single second linear transmission member 30C may intersect with multiple first linear transmission members 30A and 30B in each of multiple intersection regions. In this case, multiple first intersection sections may exist in a single second linear transmission member 30C, but the length of each of these multiple first intersection sections only needs to be larger than the maximum fixed interval of the single linear transmission member 30C.
[0056] In one intersection section of the linear transmission members 30C, the linear transmission members 30A and 30B serve as upper linear transmission members, and the linear transmission member 30C serves as a lower linear transmission member.
[0057] At least one of the six first linear transmission members 30A and 30B is a thicker linear transmission member than the second linear transmission member 30C. Here, two of the four linear transmission members 30B1 are thicker linear transmission members.
[0058] exist Figure 2 In the example shown, both the linear transmission member 30B1 and the linear transmission member 30C are single-core, standard electric wires. Because the conductor cross-sectional area of the linear transmission member 30B1 is larger than that of the linear transmission member 30C, the linear transmission member 30B1 is thicker than the linear transmission member 30C. However, the configuration in which the thick-diameter linear transmission member is thicker than the linear transmission member 30C is not particularly limited and can be set as appropriate. For example, the thick-diameter linear transmission member can be thicker than the linear transmission member 30C by being a shielded wire with a shielding layer. Furthermore, for example, the thick-diameter linear transmission member can be thicker than the linear transmission member 30C by being a multi-core wire.
[0059] In other words, the thickness of the linear transmission member 30 is determined by a complex combination of multiple factors, including the number of cores in the linear transmission member 30, the layer structure of the cored linear transmission member 30, and the thickness of each layer. The thick-diameter linear transmission member differs from the linear transmission member 30C due to these factors and is therefore thicker than the linear transmission member 30C.
[0060] In the intersection section, the sheet 20 and the linear transmission member 30 are not fixed. No fixing portion FP is provided in the intersection section. The sheet 20 and the linear transmission member 30 may also be fixed in the intersection section.
[0061] The length dimension of the second intersection section of the linear transmission member 30A is smaller than the maximum fixed interval of the linear transmission member 30A. Figure 1 As shown, dimension D1 is smaller than dimension D3. Similarly, the length dimension of the second cross section of the linear transmission member 30B is smaller than the maximum fixed interval of the linear transmission member 30B. Specifically, as shown in FIG. Figure 1 As shown, dimension D1 is smaller than dimension D4. Thus, even when the linear transmission members 30A and 30B are positioned as upper linear transmission members in the second intersecting section, they are less likely to lift from the sheet 20. It should be noted that when there are multiple first linear transmission members 30A (30B), when comparing the multiple first linear transmission members 30A (30B), at least one of the length of the second intersecting section and the maximum fixed interval may differ. In this case, the length of the second intersecting section of each first linear transmission member 30A (30B) may be smaller than the maximum fixed interval. The length of the first intersecting section of one first linear transmission member 30A (30B) may be greater than the maximum fixed interval of another first linear transmission member 30A (30B). Furthermore, a single first linear transmission member 30A (30B) may intersect with multiple second linear transmission members 30C in each of the multiple intersecting regions. In this case, a plurality of second intersecting sections exist in one first linear transmission member 30A ( 30B), but the length of each of the plurality of second intersecting sections may be smaller than the maximum fixed interval of the one linear transmission member 30A ( 30B).
[0062] The linear transmission members 30A, 30B, and 30C extend linearly in a section including the intersection 40. However, the linear transmission members 30A, 30B, and 30C may extend in a curved manner in the section including the intersection 40.
[0063] The linear transmission members 30A, 30B and the linear transmission member 30C intersect orthogonally in the intersection section. Alternatively, the linear transmission members 30A, 30B and the linear transmission member 30C may intersect obliquely in the intersection section. When the linear transmission members 30A, 30B and the linear transmission member 30C intersect obliquely in the intersection section, the intersection section becomes longer than when the linear transmission members 30A, 30B and the linear transmission member 30C intersect orthogonally.
[0064] <Effects of Embodiment 1, etc.>
[0065] If the fixed intervals in the linear transmission member 30 increase, the portion between the fixed portions FP is more likely to lift from the sheet 20. Furthermore, it becomes difficult for the upper linear transmission member to be fixed to the sheet 20 in the intersecting region. Therefore, if a linear transmission member 30 with a long intersecting region becomes the upper linear transmission member, it is more likely to lift from the sheet 20. In contrast, according to the wiring member 10 described above, the length dimension D2 of the intersecting region (first intersecting region) in the linear transmission member 30C is greater than the maximum fixed interval D5 of the fixed interval with the sheet 20, excluding at least the first intersecting region, and the linear transmission member 30C becomes the lower linear transmission member. Consequently, the linear transmission member 30C is less likely to lift from the sheet 20 than if the linear transmission member 30C were the upper linear transmission member in the intersecting region.
[0066] In addition, in the first intersection section, the linear transmission member 30C is not fixed to the sheet 20. Even in this case, the linear transmission member 30C is not easily lifted from the sheet 20 by being pressed by the plurality of linear transmission members 30A and 30B.
[0067] Furthermore, the linear transmission member 30C is pressed by the thick-diameter linear transmission member 30B1 and is therefore less likely to lift up from the sheet 20 .
[0068] Furthermore, the coating layers 32 of the plurality of linear transmission members 30 are fused to the sheet 20 . Thus, the plurality of linear transmission members 30 are easily fixed to the sheet 20 .
[0069] Furthermore, the length D1 of the intersection section (second intersection section) of the linear transmission members 30A and 30B is smaller than the largest fixed intervals D3 and D4 of the fixed intervals of the first linear transmission members 30A and 30B, excluding at least the second intersection section. This prevents the fixed intervals of the first linear transmission members 30A and 30B from increasing in the second intersection section, and also reduces the chance of the first linear transmission members 30A and 30B lifting from the sheet.
[0070] Furthermore, at least two first linear transmission members 30A and 30B are arranged parallel to each other in the parallel section, and the second linear transmission member 30C intersects with the at least two first linear transmission members 30A and 30B in the parallel section. This reduces the length D2 of the first intersecting section. However, the second linear transmission member 30C may intersect with the at least two first linear transmission members 30A and 30B in a section other than the parallel section.
[0071] [Modification]
[0072] Figure 3 It is a cross-sectional view showing a modified example of the wiring member 10 .
[0073] exist Figure 3 The wiring member 110 shown differs from the wiring member 10 described above in that the portion where the second linear transmission member is fixed to the sheet 20 is provided in the intersection region. According to this wiring member 110, since the portion where the second linear transmission member is fixed to the sheet 20 is provided in the intersection region, the second linear transmission member is less likely to lift from the sheet 20 in the intersection region.
[0074] Specifically, if Figure 3 As shown in FIG. 1 , a fixing portion FP1 is provided between two intersection portions 40AC1 and 40BC1 in the linear transmission member 30C. Figure 3 In the illustrated example, the fixing portion FP1 is provided in the portion between the upper linear transmission members of the linear transmission member 30C. The fixing portion FP1 may also be provided in portions other than these portions. The spacing between the upper linear transmission members on either side of the fixing portion FP1 is wider than the spacing between the other upper linear transmission members. The spacing between the upper linear transmission members on either side of the fixing portion FP1 may not be wider than the spacing between the other upper linear transmission members. The fixing portion FP may also be provided in the portion of the linear transmission member 30C that overlaps with the upper linear transmission members.
[0075] Furthermore, in wiring member 110, no thick-diameter linear transmission member is provided as the upper linear transmission member. Linear transmission members 30A and 30B are the same size as or thinner than linear transmission member 30C. In this case, the force exerted by linear transmission members 30A and 30B pressing against linear transmission member 30C is weaker than when thick-diameter linear transmission members are provided. In such cases, it is preferable to provide fixing portion FP1.
[0076] In addition, the fixed intervals of the first linear transmission members 30A and 30B including the second intersection interval (with respect to Figure 1The distance between the fixing portion FP on the left and the fixing portion FP on the right of the line indicating dimension D1 can be smaller than the maximum fixing distances D3 and D4 excluding the second intersection section. This prevents the fixing distance between the first linear transmission members 30A and 30B from increasing in the second intersection section, and makes it less likely that the first linear transmission members 30A and 30B will lift off the sheet 20.
[0077] In addition, the above description assumes that the intersection region A1 is provided for branching the plurality of linear transmission members 30, but this is not a required configuration. The intersection region may also be provided to change the arrangement order of the plurality of linear transmission members 30. In this case, it is preferable that the two linear transmission members 30 forming the intersection portion are arranged in parallel on both sides of the intersection portion.
[0078] In addition, the description thus far assumes that the wiring members 10 and 110 are provided with a single intersection region A1, but this is not a required configuration. Multiple intersection regions may be provided in the wiring member. Here, focusing on the relationship between the length of the intersection section and the maximum fixed interval in the upper linear transmission member, and the relationship between the length of the intersection section and the maximum fixed interval in the lower linear transmission member, the intersection region is divided into the following four intersection regions.
[0079] The first intersection region is an intersection region where the length of the intersection section of the upper linear transmission member is less than the maximum fixed interval and the length of the intersection section of the lower linear transmission member is longer than the maximum fixed interval. For example, the intersection region A1 is the first intersection region.
[0080] The second intersection region is an intersection region where the length of the intersection section of the upper linear transmission member is less than or equal to the maximum fixed interval, and the length of the intersection section of the lower linear transmission member is less than or equal to the maximum fixed interval. For example, the intersection region where the number of upper and lower linear transmission members is small is a second intersection region.
[0081] The third intersection region is an intersection region where the length of the intersection section of the upper linear transmission member is longer than the maximum fixed interval, and the length of the intersection section of the lower linear transmission member is less than the maximum fixed interval. For example, the intersection region formed by swapping the upper and lower linear transmission members in the intersection region A1 is the third intersection region.
[0082] The fourth intersection region is an intersection region where the length of the intersection section of the upper linear transmission member is longer than the maximum fixed interval, and the length of the intersection section of the lower linear transmission member is longer than the maximum fixed interval. For example, the intersection region where the number of upper and lower linear transmission members is large is the fourth intersection region.
[0083] When the wiring member has multiple intersection regions, some or all of the intersection regions may be first intersection regions. This can suppress warping of the second linear transmission member in the first intersection regions. When some of the multiple intersection regions are first intersection regions, the intersection regions other than the first intersection regions are preferably second intersection regions. This can suppress warping of the linear transmission member 30 in the multiple intersection regions. It is also possible to provide a third or fourth intersection region in the wiring member.
[0084] A member that prevents the linear transmission member 30 from warping may be provided in the intersection region. For example, the member that prevents the linear transmission member 30 from warping may be a cover sheet that covers the intersection region. Alternatively, the member that prevents the linear transmission member 30 from warping may be a bonding member such as an adhesive or pressure-sensitive adhesive that bonds the upper and lower linear transmission members.
[0085] When the wiring member is provided with multiple intersection regions, a single linear transmission member 30 may form intersections in multiple intersection regions. A single linear transmission member 30 may serve as an upper linear transmission member at the intersections in multiple intersection regions. A single linear transmission member 30 may serve as a lower linear transmission member at the intersections in multiple intersection regions. A single linear transmission member 30 may serve as an upper linear transmission member at the intersection in one intersection region and as a lower linear transmission member at the intersections in other intersection regions. For example, the linear transmission members 30A and 30B may serve as either an upper linear transmission member or a lower linear transmission member at the intersection in an intersection region different from intersection region A1. Furthermore, for example, the linear transmission member 30C may serve as either a lower linear transmission member or an upper linear transmission member at the intersection in an intersection region different from intersection region A1.
[0086] As described above, the sheet 20 and the linear transmission member 30 may be secured by fusion or by a method other than fusion. The sheet 20 and the linear transmission member 30 may be secured by contact or non-contact locations, or a combination of both. Contact location securement refers to the contacting portions of the sheet 20 and the linear transmission member 30 being in close contact and secured. Non-contact location securement refers to a method other than contact location securement, such as using sutures, a cover, or adhesive tape to press the linear transmission member 30 toward the sheet 20, or to sandwich the sheet 20 and the linear transmission member 30 and maintain this position.
[0087] The contact point fixation method can be indirect contact point fixation, direct contact point fixation, or a combination of both in different areas. Indirect contact point fixation refers to the sheet 20 and the linear transmission member 30 being in close contact and fixed indirectly via an intermediate adhesive, sticky agent, double-sided adhesive tape, or the like. Direct contact point fixation refers to the sheet 20 and the linear transmission member 30 being in direct close contact and fixed without the use of a separate adhesive or the like. Direct contact point fixation can be achieved, for example, by melting or dissolving a resin contained in at least one of the sheet 20 and the linear transmission member 30 to achieve close contact and fixation.
[0088] When achieving this direct fixation of the contact portions, the resin can be melted by heat or dissolved by a solvent, for example. In other words, the direct fixation of the contact portions can be achieved by either heat or solvent. The preferred method is direct fixation of the contact portions by heat.
[0089] At this time, the means for achieving a directly fixed state of the contact portions is not particularly limited, but known means such as fusion can be used. For example, when achieving a directly fixed state of the contact portions by heat through fusion, various fusion means such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high-frequency fusion can be used. Furthermore, if a directly fixed state of the contact portions is achieved by these means, the sheet 20 and the linear transmission member 30 are in a state of directly fixed contact portions by this means. Specifically, for example, if a directly fixed state of the contact portions is achieved by ultrasonic fusion, the sheet 20 and the linear transmission member 30 are in a state of directly fixed contact portions by ultrasonic fusion. Therefore, the above-described fusion fixation is one form of directly fixed contact portions.
[0090] It should be noted that the configurations described in the above-mentioned embodiments and modifications can be appropriately combined as long as they do not conflict with each other.
