Summary of the Invention

Problems to be Solved by the Invention

[0004] Conditions suitable for fusing a special wire such as a twisted wire to a base member are often different from those suitable for fusing a normal wire such as a single-core electric wire to a base member.

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.

[0010] The wiring components of this disclosure are as follows:

[0011] (1) A wiring member comprising a base member and a standard wire fused to the base member, and a special wire fixed to the wiring member via a fixing part, wherein the fixing part is fixed in a manner different from the fusion of the base member and the special wire. Because the fixing part is fixed in a manner different from the fusion of the base member and the special wire, the standard wire and the special wire can be easily fixed to the base member.

[0012] (2) In the wiring member of (1), the fixing portion may include a binding portion where the wiring body and the special wire are bound by a binding member. Thereby, the special wire can be fixed without fusion.

[0013] (3) In the wiring member of (2), in the binding portion, the normal wire and the special wire may be bound by the binding member. Thereby, the special wire is fixed to the base member via the normal wire fixed to the base member.

[0014] (4) In the wiring member of (3), a side edge of the base member is recessed, and a portion of the normal wire passing over the recessed portion of the side edge of the base member may be bound to the special wire. Thereby, in the middle portion of the base member, the special wire and the normal wire can be easily bound.

[0015] (5) In the wiring member of (3) or (4), a plurality of the normal wires are arranged in parallel, and a part of the plurality of parallel normal wires may be bound to the special wire. Thereby, the special wire is fixed without winding a binding member around the entire periphery of the wiring body.

[0016] (6) In the wiring member of (2), in the binding portion, the base member and the special wire may be bound by the binding member. Thereby, the special wire is fixed to the base member via the binding member.

[0017] (7) In any one of the wiring members from (2) to (6), a plurality of fusion portions between the base member and the normal wire are provided at intervals in the longitudinal direction of the normal wire, and the binding portion may be provided between the plurality of fusion portions. Thereby, the special wire is fixed at the position of the middle portion in the base member.

[0018] (8) In the wiring member of (1), the base member is a first base member, and the fixing portion may include a fixing portion between a second base member different from the first base member and the special wire, and a fixing portion between the first base member and the second base member. Thus, the first base member to which the normal wire is fixed and the second base member to which the special wire is fixed are fixed, whereby the special wire is fixed to the wiring body.

[0019] [Details of Embodiments of the Present Disclosure] Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, and is shown by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.

[0020] [Embodiment 1] Hereinafter, the wiring member according to Embodiment 1 will be described. FIG. 1 is a schematic plan view showing a wiring member 10 according to Embodiment 1. FIG. 2 is a partial enlarged view of FIG. 1. FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 2.

[0021] The wiring member 10 includes a wiring body 20 and a special wire 50. The wiring body 20 includes a base member 30 and a normal wire 40. The normal wire 40 is fused to the base member 30.

[0022] The base member 30 may be any member as long as it has an arrangement surface on which the normal wire 40 is arranged. Hereinafter, it will be described assuming that the base member 30 is a sheet 30. The sheet 30 includes a fusion layer 31. The fusion layer 31 includes a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer 31 softens and fuses to the fusion partner. The type of such a resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be adopted.

[0023] The structure of the fusion layer 31 is not particularly limited. For example, the fusion layer 31 may be a sheet with a uniformly solid cross-section (also called a non-foamed sheet or solid sheet). Alternatively, the fusion layer 31 may be a foamed sheet or the like. Alternatively, the fusion layer 31 may be a fibrous sheet such as a knitted fabric, woven fabric, or nonwoven fabric.

[0024] The sheet 30 may have a single-layer structure consisting of a fusion layer 31. The sheet 30 may have a multi-layer structure. If the sheet 30 has a multi-layer structure, it is preferable that the fusion layer 31 appears on at least one main surface of the sheet 30. Here, the sheet 30 includes a fusion layer 31 and an additional layer 32. A normal wire 40 is fused to the fusion layer 31. One surface of the fusion layer 31 is designated as one main surface of the sheet 30.

[0025] The additional layer 32 may be made of a different material or have a different structure than the fusion layer 31. The additional layer 32 enhances the functions of the fusion layer 31 or adds functions to the sheet 30 that are not present in the fusion layer 31. The material constituting the additional layer 32 may be a metal or the like, in addition to the materials described for the fusion layer 31. The structure of the additional layer 32 may be any of the structures described for the fusion layer 31. One surface of the additional layer 32 becomes the other main surface of the sheet 30.

[0026] The fusion layer 31 and the additional layer 32 are fixed together while the other surface of the fusion layer 31 and the other surface of the additional layer 32 are in contact. The manner in which the fusion layer 31 and the additional layer 32 are fixed together is not particularly limited, but it is preferable that they be fixed by fusion or adhesive. For example, if at least one of the fusion layer 31 and the additional layer 32 is a sheet with voids on its surface, such as a fibrous sheet or a foamed sheet, then a resin material or adhesive can fill the voids and fix them together. This produces a so-called anchoring effect, firmly fixing the fusion layer 31 and the additional layer 32 together.

[0027] Here, the fusion layer 31 is described as a solid sheet made of resin, and the addition layer 32 is described as a fibrous sheet. Here, the fusion layer 31 and the addition layer 32 are described as being fused together. In other words, the resin of the fusion layer 31 enters between the fibers of the addition layer 32 while in a fluid state, and then hardens. As a result, the state in which the resin of the fusion layer 31 enters between the fibers of the addition layer 32 is maintained, and the fusion layer 31 and the addition layer 32 are firmly fixed together.

[0028] The fusion layer 31 and the additional layer 32 are formed to be the same size (same planar shape). One of the fusion layer 31 and the additional layer 32 may be formed to be larger than the other. The entire contact area of ​​the fusion layer 31 and the additional layer 32 is fixed. Only a portion of the contact area of ​​the fusion layer 31 and the additional layer 32 may be fixed.

[0029] The sheet 30 may be made of a soft material. For example, the fusion layer 31 may be a resin layer with a uniform solid cross-section made of a soft resin such as soft PVC, and the additional layer 32 may be a nonwoven fabric made of PET, so that the sheet 30 is made of a soft material. For example, the sheet 30 may normally have flexibility that can follow the bending of the wire 40. In other words, the wiring member 10 may be able to be bent in the thickness direction (bending so that the folds follow the main surface of the sheet 30).

[0030] The standard wire 40 is a linear component that transmits electricity or light, etc. The sheet 30 is formed in a flat shape overall. The wiring body 20 is kept in a flat shape by fixing the standard wire 40 to the sheet 30. The special wire 50 is also a linear component that transmits electricity or light, etc. The special wire 50 is fixed to the flat wiring body 20, keeping the wiring member 10 in a flat shape. The standard wire 40 and special wire 50 that transmit electricity may be various signal lines or various power lines. Parts of the standard wire 40 and special wire 50 that transmit electricity may be used as antennas, coils, etc. that send signals or power to or receive signals or power from space.

[0031] Here, the standard wire 40 is assumed to be a single-core wire 40, and the special wire 50 is assumed to be a twisted wire 50. The single-core wire 40 has one core wire 41 and a covering layer 42 that covers the core wire 41. The core wire 41 is a single conductive path composed of one or more strands. The covering layer 42 is formed by extruding a resin material around the core wire 41. The twisted wire 50 is made by twisting together multiple covered wires 51. Figure 3 shows a twisted pair wire as a typical example of the twisted wire 50. The circular area R shown by the dashed line in Figure 3 indicates the range in which the multiple covered wires 51 in the twisted wire 50 move. The same applies to the following figures.

[0032] However, the combination of the standard wire 40 and the special wire 50 is not limited to this. For example, the special wire 50 may be a material that is more difficult to fuse to the sheet 30 than the standard wire 40. More difficult to fuse to the sheet 30 than the standard wire 40 means not only that it cannot be fused to the sheet 30, but also that even if it can be fused to the sheet 30, it takes more effort to fuse to the sheet 30 than the standard wire 40, or the fusion strength to the sheet 30 is lower than that of the standard wire 40 when fused under the same fusion conditions. For example, the special wire 50 may be more difficult to fuse to the sheet 30 than the standard wire 40 because it has more transmission lines or a more multilayered structure than the standard wire 40. Also, for example, the special wire 50 may be more difficult to fuse to the sheet 30 than the standard wire 40 because its cross-sectional shape is not uniform along its longitudinal direction, resulting in an uneven reaction force when pressed during fusion. For example, the special wire 50 is more difficult to fuse to the sheet 30 than the regular wire 40 because its coating layer is made of a material that is more difficult to fuse to the sheet 30 than the coating layer 42 of the regular wire 40.

[0033] In the twisted wire 50, the arrangement of the insulated wires 51 changes periodically along its longitudinal direction. Therefore, the twisted wire 50 on the sheet 30 periodically has portions where the insulated wires 51 are stacked vertically on the sheet 30 (hereinafter referred to as the vertically aligned portion) and portions where they are aligned horizontally on the sheet 30 (hereinafter referred to as the horizontally aligned portion). Furthermore, even when fused under the same fusion conditions, the fusion strength to the sheet 30 may differ between the vertically aligned portion and the horizontally aligned portion. In addition, selectively fusing either the vertically aligned portion or the horizontally aligned portion of the twisted wire 50 is time-consuming. For these reasons, the twisted wire 50 is considered more difficult to fuse to the sheet 30 than a single-core wire.

[0034] The standard wire 40 and the special wire 50 are assumed to be components that connect parts to each other in a vehicle. Connectors C are provided at the ends of the standard wire 40 and the special wire 50, for example. By connecting these connectors C to connectors provided on the mating parts, the standard wire 40 and the special wire 50 are connected to the mating parts. In other words, this wiring member 10 is used as a wiring member 10 that electrically (or optically) connects various parts to each other in a vehicle, etc. Connector C may be fixed to the sheet 30. In the example shown in Figure 1, one end of the special wire 50 is incorporated into the same connector C into which the end of the standard wire 40 is incorporated. The other end of the special wire 50 is incorporated into a different connector C than the one into which the end of the standard wire 40 is incorporated. However, both ends of the special wire 50 may be incorporated into the same connector C into which the end of the standard wire 40 is incorporated. Also, both ends of the special wire 50 may be incorporated into different connectors C than the one into which the end of the standard wire 40 is incorporated.

[0035] The routes of the standard wires 40 and special wires 50 are set according to the location of the component to which they are connected. The standard wires 40 are fixed to the sheet 30, thereby maintaining them along the wiring route according to the location of the component to which they are connected. The standard wires 40 may also be fixed to the sheet 30 in a manner in which branch wires branch off from the main wire. The sheet 30 may also be formed in a shape in which the part where the main wire is fixed branches off from the part where the branch wire is fixed. Here, the standard wires 40 branch on the sheet 30. The sheet 30 branches according to the branching shape of the standard wires 40. The special wires 50 are fixed to the wiring body 20, thereby maintaining them along the wiring route according to the location of the component to which they are connected.

[0036] In the example shown in Figure 1, the special line 50 extends along at least one of the normal lines 40 in the portion where the normal lines 40 are placed on the sheet 30. The special line 50 may extend in a different direction from the normal lines 40 in the portion where the normal lines 40 are placed on the sheet 30. The special line 50 may branch off from other normal lines 40. For example, in Figure 1, the normal line 40 may extend between a connector C located to the left of the branch and a connector C located above the branch, and the special line 50 may extend between a connector C located to the left of the branch and a connector C located to the right of the branch.

[0037] The portion where the sheet 30 and the normal line 40 are fused together is called the fusion joint WP. Here, multiple fusion joints WP are provided at intervals along the longitudinal direction of the normal line 40. In the example shown in Figure 1, the fusion joints WP are provided at the ends of the straight sections (the boundary between the straight section and the curve) and at the ends of the sheet 30. Also, if the straight section is long, the fusion joints WP are provided in the middle of the straight section. In the example shown in Figure 1, the fusion joints WP are not provided in the middle of the curved section, but they may be provided in the middle of the curved section. However, the fusion joints WP may be provided in a continuous line along the longitudinal direction of the normal line 40 from one end to the other of the sheet 30.

[0038] The means for forming the fused state between the sheet 30 and the normal wire 40 are not particularly limited, and various fusion methods such as ultrasonic fusion, heat and pressure fusion, hot air fusion, and high-frequency fusion can be employed. When the fused state is formed by these means, the fused portion WP is fixed by that means. Specifically, for example, if the fused portion WP is formed by ultrasonic fusion, the fused portion WP becomes an ultrasonically fused portion.

[0039] The sheet 30 and the normal wire 40 are fused together by at least one of their resin materials melting and adhering to the other. Preferably, both the sheet 30 and the normal wire 40 are fused together by both of their resin materials melting and adhering to each other. The resin material constituting the fusion layer 31 is preferably of the same type as the resin material constituting the coating layer 42. For example, both the resin material constituting the fusion layer 31 and the resin material constituting the coating layer 42 may be PVC.

[0040] The special wire 50 is fixed to the wiring body 20 via a fixing part 12. The fixing part 12 is fixed in a manner different from fusion bonding between the sheet 30 and the special wire 50. Here, the fixing part 12 is a binding part 12. The binding part 12 is the part where the wiring body 20 and the special wire 50 are bound and fixed together by a binding member 60. Here, the wiring member 10 is provided with multiple (four in this case) fixing parts 12. All four fixing parts 12 are binding parts 12. The four fixing parts 12 may include fixing parts other than binding parts 12.

[0041] Here, in the binding section 12, the regular wire 40 and the special wire 50 are bound together by the binding member 60. In the binding section 12, the sheet 30 is not bound to the special wire 50. In the binding section 12, of the regular wire 40 and the sheet 30, only the regular wire 40 is bound to the special wire 50. Such a binding section 12 may be called a regular wire binding section. Here, all four binding sections 12 are regular wire binding sections. The four binding sections 12 may include binding sections 12 other than regular wire binding sections (for example, the base member binding section or wiring body fixing section described later).

[0042] The fastening member 60 can be anything as long as it can fasten the wiring body 20 (in this case, the ordinary wire 40) and the special wire 50. For example, the fastening member 60 may be an adhesive tape or a cable tie. The adhesive tape includes, for example, a base layer and an adhesive layer. The adhesive layer is laminated on one surface of the base layer. The cable tie includes, for example, a band portion and a band fixing portion. The band fixing portion is connected to the base end of the band portion and can fix the tip of the band portion wrapped around the object to be fastened. The cable tie may be a cable tie in which the extending direction of the band portion is restricted so that it can be wrapped around the object to be fastened in a flattened position. The cable tie may be a normal cable tie in which the extending direction of the band portion is not restricted. The fastening member 60 may be wrapped around the twisted wire 50, for example, along a circular range R which is the range in which the insulated wire 51 moves.

[0043] Here, in two of the four standard wire binding sections 12a, the portion of the standard wire 40 that extends outward along the longitudinal direction of the sheet 30 is bound. In two of the four standard wire binding sections 12b, the portion of the standard wire 40 located in the middle of the sheet 30 along the longitudinal direction of the sheet 30 is bound. The standard wire binding sections 12b are provided between multiple fusion sections WP. The four standard wire binding sections 12 are arranged in the order of standard wire binding sections 12a, 12b, 12b, 12a along the longitudinal direction of the special wire 50 from one end to the other. Between each of the two sets of standard wire binding sections 12a and 12b, the standard wire 40 and the special wire 50 extend in a straight line. Between the two standard wire binding sections 12b, there is a section where the standard wire 40 and the special wire 50 bend. In the example shown in Figure 1, in the section where the normal line 40 and the special line 50 bend, the special line 50 is located on the outer circumference side of the normal line 40. In the section where the normal line 40 and the special line 50 bend, the special line 50 may be located on the inner circumference side of the normal line 40. Instead of the two normal line binding sections 12b, one normal line binding section may be provided where the normal line 40 and the special line 50 bend. In other words, the special line 50 bends and extends inside the normal line binding section, and the special line 50 may extend in directions that intersect each other on one side and the other side of the normal line binding section.

[0044] The standard wire binding section 12b is provided at the location of the recess 33 of the sheet 30. The recess 33 is a recessed portion of the side edge of the sheet 30. Here, the recess 33 is recessed along the width direction of the sheet 30 to the portion that overlaps with the standard wire 40. Therefore, the depth dimension of the recess 33 is greater than the dimension from the standard wire 40 closest to the side edge of the sheet 30 along the width direction of the sheet 30 to that side edge. Also, here, the recess 33 is recessed to the portion between the parallel standard wires 40 along the width direction of the sheet 30. Therefore, the depth dimension of the recess 33 is smaller than the dimension from the standard wire 40 furthest from the side edge of the sheet 30 along the width direction of the sheet 30 to that side edge. The width dimension of the recess 33 (dimension along the longitudinal direction of the standard wire 40) should be the same as or greater than the width dimension of the binding member 60 (in this case, adhesive tape). In the standard wire binding section 12, the portion of the standard wire 40 that passes over the recess 33 of the sheet 30 is bound to the special wire 50. The binding member 60 fastens the regular wire 40 and the special wire 50 by passing through the recess 33.

[0045] In the wiring member 10, there is a parallel section in which multiple ordinary wires 40 run parallel to each other. An ordinary wire bundling section 12 is provided in the parallel section. In the parallel section, some of the ordinary wires 40 among the multiple parallel ordinary wires 40 are bundled with the special wire 50. In all four ordinary wire bundling sections 12, some of the ordinary wires 40 among the multiple parallel ordinary wires 40 are bundled with the special wire 50. Such an ordinary wire bundling section 12 may be called a partial wire bundling section. In some or all of the four ordinary wire bundling sections 12, all of the multiple parallel ordinary wires 40 may be bundled with the special wire 50. Such an ordinary wire bundling section may be called a full wire bundling section.

[0046] The number of ordinary wires 40 bound at the ordinary wire binding section 12 may be one or multiple. If there are multiple ordinary wires 40 bound at the ordinary wire binding section 12, the spacing between the ordinary wires 40 at the ordinary wire binding section 12 may be the same as the spacing between the ordinary wires 40 on the sheet 30 (the spacing between the ordinary wires 40 at the position where the fusion section WP is formed), or it may be narrower. The ordinary wires 40 may be spaced apart on the sheet 30, and may be in contact with each other at the ordinary wire binding section 12. At the ordinary wire binding section 12, the special wire 50 and the adjacent ordinary wire 40 may be in contact or separated.

[0047] If the binding member 60 is adhesive tape, a portion of the adhesive tape (the portion wrapped above the special wire 50 and the regular wire 40 in Figure 3) and another portion (the portion wrapped below the special wire 50 and the regular wire 40 in Figure 3) may be adhered together between the special wire 50 and the adjacent regular wire 40. This keeps the special wire 50 and the adjacent regular wire 40 separated. Similarly, between the regular wires 40, a portion of the adhesive tape may be adhered together to keep the regular wires 40 separated.

[0048] <Effects of Embodiment 1> With the wiring member 10 configured as described above, the fixing portion 12 is fixed in a manner different from fusion bonding between the sheet 30 and the special wire 50, so that the ordinary wire 40 and the special wire 50 can be easily fixed to the sheet 30.

[0049] Furthermore, the fixing section 12 includes a binding section 12 in which the wiring body 20 and the special wire 50 are bound together by a binding member 60. This allows the special wire 50 to be fixed to the wiring body 20 without the need for fusion bonding.

[0050] Furthermore, at the binding section 12, the regular wire 40 and the special wire 50 are bound together by the binding member 60. As a result, the special wire 50 is fixed to the sheet 30 via the regular wire 40 which is fixed to the sheet 30.

[0051] Furthermore, the portion of the regular wire 40 that passes through the recess 33 of the sheet 30 is bound to the special wire 50. This makes it possible to easily bind the special wire 50 and the regular wire 40 in the middle section of the sheet 30.

[0052] Furthermore, some of the parallel regular wires 40 are bundled with the special wires 50. This allows the special wires 50 to be secured without having to wrap the binding member 60 around the entire circumference of the wiring body 20.

[0053] Furthermore, a binding section 12 is provided between multiple fusion sections WP. This fixes the special wire 50 to the middle section of the sheet 30.

[0054] [Embodiment 2] A wiring member according to Embodiment 2 will now be described. Figure 5 is a schematic plan view showing a wiring member 110 according to Embodiment 2. Figure 6 is a cross-sectional view taken along the line VI-VI in Figure 5. In the following description, components similar to those described above will be denoted by the same reference numerals and their descriptions will be omitted.

[0055] In the wiring member 110, the structure of the binding portion 112 differs from the structure of the binding portion 12 in the wiring member 10. Specifically, in the binding portion 112, the sheet 130 and the special wire 50 are bound together by a binding member 60. As a result, the special wire 50 is fixed to the sheet 130 via the binding member 60.

[0056] In the binding section 112, the normal wire 40 is not bound to the special wire 50. In the binding section 112, of the normal wire 40 and the sheet 130, only the sheet 130 is bound to the special wire 50. Such a binding section 112 may also be called a base material binding section 112.

[0057] The sheet 130 is provided with a portion for being bound to the special wire 50 by a binding member 60. Specifically, the sheet 130 has a normal wire arrangement portion 134 and an extension portion 135. The normal wire arrangement portion 134 is the portion where the normal wire 40 is arranged and fixed. The extension portion 135 is the portion that extends from the normal wire arrangement portion 134. The normal wire 40 is not fixed to the extension portion 135. Here, the extension portion 135 has a lateral extension portion 135a and a longitudinal extension portion 135b. The lateral extension portion 135a is the portion that extends laterally from the normal wire arrangement portion 134. The longitudinal extension portion 135b is the portion that extends from the lateral extension portion 135a in the longitudinal direction of the lateral extension portion 135a. The side edge of the longitudinal extension portion 135b is not connected to the side edge of the normal wire arrangement portion 134. Here, at the binding section 112, the special wire 50 is positioned on the extension section 135 of the sheet 130. The longitudinal extension section 135b of the extension section 135 is bound to the special wire 50. On the sheet 130, the transverse extension section 135a continues in a series along the longitudinal direction of the normal wire arrangement section 134. The transverse extension section 135a may be provided at multiple locations at intervals along the longitudinal direction of the normal wire arrangement section 134. The extension section may be formed in a planar shape such as an L-shape or a T-shape, having both a transverse extension section and a longitudinal extension section, and may be provided partially along the longitudinal direction of the normal wire arrangement section 134.

[0058] However, as shown in the following modified example, the special wire 50 does not necessarily have to be placed on the extension portion 135 of the sheet 130.

[0059] Figure 7 is a schematic plan view showing a modified example of the wiring member 110 according to Embodiment 2. Figure 8 is a cross-sectional view taken along the line VIII-VIII in Figure 7. In the wiring member 210 shown in Figure 7, the special wire 50 is not arranged on the sheet 230. The special wire 50 is arranged to the side of the sheet 230. The longitudinal extension portion 235 on the sheet 230 extends longitudinally from the longitudinal end of the normal wire arrangement portion 134. The longitudinal extension portion 235 is not fixed to the normal wire 40. In the binding portion 212, the binding member 60 binds the longitudinal extension portion 235 and the special wire 50. A part of the binding member 60 is located between the normal wire 40 and the longitudinal extension portion 235. Alternatively, the special wire 50 may be arranged to the side of the extension portion 135 on the sheet 130, and the longitudinal extension portion 135b may be bound to the special wire 50.

[0060] [Embodiment 3] A wiring member according to Embodiment 3 will now be described. Figure 9 is a schematic plan view showing a wiring member 310 according to Embodiment 3. Figure 10 is a cross-sectional view taken along line XX in Figure 9.

[0061] The wiring member 310 differs from the above-mentioned wiring members 10, 110, and 210 in that the fixing parts 14 and 16 are not the bundling parts 12, 112, and 212. Specifically, in the wiring member 310, the sheet 330 in the wiring body 20, that is, the sheet 330 to which the ordinary wire 40 is fused, is referred to as the first sheet 330. The special wire 50 is fixed to a second sheet 70, which is separate from the first sheet 330. The second sheet 70 is an example of a second base member. The fixing part 14 between the second sheet 70 and the special wire 50 is referred to as the special wire fixing part 14. The first sheet 330 and the second sheet 70 are fixed together. The fixing part 16 between the first sheet 330 and the second sheet 70 is referred to as the base member fixing part 16. Therefore, the fixing parts 14 and 16 in the wiring member 310 include the special wire fixing part 14 and the base member fixing part 16. In this way, the special wire 50 is fixed to the wiring body 20 by fixing the first sheet 330 to which the regular wire 40 is fixed and the second sheet 70 to which the special wire 50 is fixed.

[0062] The first sheet 330 and the second sheet 70 are preferably fixed together at their side edges. The first sheet 330 has a normal line arrangement section 134 and a lateral extension section 335. The second sheet 70 has a special line arrangement section 71 and a lateral extension section 72. A base member fixing section 16 is provided in the portion where the lateral extension section 335 and the lateral extension section 72 overlap.

[0063] The special wire fixing part 14 and the base member fixing part 16 may be of the same type of fixing method or of different types of fixing methods. Such fixing methods may be any type of fixing method. For example, such fixing methods may be adhesive parts fixed via an intermediary member such as adhesive or double-sided adhesive tape. Alternatively, such fixing methods may be sewn parts sewn with thread. Alternatively, such fixing methods may be locking parts using locking components such as rivets or staplers. Alternatively, such fixing methods may be fused parts. Even when a fused part is used as the special wire fixing part 14, the special wire 50 is fused to a second sheet 70 that is different from the first sheet 30 to which the ordinary wire 40 is fused. Therefore, the special wire 50 and the second sheet 70 can be fused at the fused part as the special wire fixing part 14 under fusion conditions suitable for the special wire 50. Therefore, compared to the case where the regular wire 40 and the special wire 50 are fused together to the first sheet 330, the special wire 50 and the second sheet 70 can be fused together more easily.

[0064] [Note] Up to this point, the special wire 50 has been described as a twisted wire 50, but this is not a mandatory configuration. For example, the special wire 50 may be a coaxial cable, an Ethernet® cable, an optical fiber cable, etc. Also, for example, if the coating layer 42 of the normal wire 40 is made of the same resin material as the fusion layer 31, the special wire 50 may be a single-core wire having a coating layer made of a different material than the fusion layer 31. For example, if the coating layer 42 of the fusion layer 31 and the normal wire 40 is PVC, the special wire 50 may be a single-core wire having a coating layer other than PVC. In this case, the resin material constituting the coating layer of the special wire 50 is not particularly limited as long as it is other than PVC, and may be, for example, polyolefins such as PE and PP, silicone resin, or fluororesin such as polytetrafluoroethylene. Such resin materials may be halogen-free. Halogen-free means that chlorine and bromine, which are halogens, are not contained, or if they are contained, they are only in trace amounts. For example, the IEC (International Electrotechnical Commission) standard defines halogen-free materials as those with a chlorine and bromine content of 900 ppm or less each, and a total chlorine and bromine content of 1500 ppm or less. Halogen-free linear transmission materials are also called non-halogen wires (for example, non-halogen electric wires in the case of electric wires).

[0065] Up to this point, an example has been described in which there is one special wire 50, but there may be multiple special wires 50. Multiple special wires 50 may be arranged on only one side of the wiring body 20, as in the wiring member 10 described above. Multiple special wires 50 may be arranged on both sides of the wiring body 20.

[0066] To date, examples have been described in which the binding portion 12 is either a standard wire binding portion 12 or a base material binding portion 112. However, the binding portion 12 may also bind both the standard wire 40 and the sheet 30 together with the special wire 50. Such a binding portion 12 may be called a wiring body binding portion. For example, when the wiring body 20 and the special wire 50 are in the positional relationship shown in Figure 7, the wiring body binding portion may be a binding member 60 that binds the longitudinal extension portion 235, the two standard wires 40 on the longitudinal extension portion 235, and the special wire 50 together.

[0067] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of Symbols]
