[0018] [Description of embodiments of this disclosure]

[0019] The embodiments of this disclosure will be described first.

[0020] The wiring components disclosed herein are as follows.

[0021] (1) The wiring component comprises: a sheet, a retaining member fixed to the sheet, and a first linear transmission member held by the retaining member. The retaining member includes a retaining portion having a groove and a protrusion that narrows the width of the opening of the groove, and the first linear transmission member is received in the groove. The first linear transmission member is held by the retaining member fixed to the sheet. Because a protrusion is formed in the retaining portion, the first linear transmission member is not easily detached from the groove. Thus, regardless of the type of linear transmission member, it can be easily fixed to the sheet.

[0022] (2) In the wiring component of (1), the wiring component may also include a second linear transmission member fused to the sheet. Thus, in the wiring component, the second linear transmission member is directly held to the sheet.

[0023] (3) In the wiring assembly of (1) or (2), the retaining member may also be fused to the sheet. Thus, the component for fixing the sheet to the retaining member can be omitted in the wiring assembly.

[0024] (4) In any of the wiring components in (1) to (3), the first linear transmission component may include a linear transmission component with a coating layer made of a first resin material, and the surface of the sheet in which the first linear transmission component is disposed may be made of a second resin material different from the first resin material. Thus, the first linear transmission component, which is difficult to weld to the sheet, is fixed to the sheet by a retaining member.

[0025] (5) In any of the wiring components in (1) to (4), there may be multiple retaining members provided in the width direction of the sheet. Therefore, when the wiring component bends about an axis along the length direction, the sheet easily bends between the retaining members, and the bending of the retaining members is suppressed. Therefore, when the wiring component bends about an axis along the length direction, the linear transmission member is less likely to detach from the retaining members.

[0026] (6) In any of the wiring components in (1) to (5), the protrusion may be formed by thermally deforming the front end of the sidewall portion of the slot. This simplifies the shape of the retaining member before the protrusion is formed.

[0027] (7) In any of the wiring components in (1) to (6), the retaining members may be provided at multiple locations spaced apart along the length of the first linear transmission member, and the retaining members at these multiple locations may be fixed to one of the sheets. Thus, the multiple retaining members are positioned by the sheet. Furthermore, compared to the case where retaining members are provided throughout the entire first linear transmission member, the area where the retaining members are provided can be reduced.

[0028] [Details of the embodiments disclosed herein]

[0029] Specific examples of wiring components of this disclosure will now be described with reference to the accompanying drawings. Furthermore, this disclosure is not limited to these examples, but is shown in the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0030] [Implementation Method 1]

[0031] The wiring component 10 according to Embodiment 1 will be described below. Figure 1 This is a schematic top view of the wiring component 10 according to Embodiment 1. Figure 2 It is along Figure 1 A cross-sectional view cut off by line II-II. Figure 3 This is an exploded top view of the wiring component 10 according to Embodiment 1.

[0032] The wiring component 10 includes a sheet 20, a retaining component 30, and a plurality of linear transmission components 40.

[0033] The sheet 20 includes a weld layer 21. Here, the sheet 20 has a double-layer structure of weld layer 21 and additional layer 22. The sheet 20 may have a single-layer structure or a structure of three or more layers.

[0034] The weld layer 21 comprises a resin material, preferably a thermoplastic resin material. The resin material of the weld layer 21 softens and fuses to the welded object. The type of resin material is not particularly limited and can include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. One surface of the weld layer 21 is the surface of the sheet 20 that contacts the holding member 30 and a portion of the linear transport member 40.

[0035] The construction of the welded layer 21 is not particularly limited. For example, the welded layer 21 can be a sheet with a uniform solid cross-section (also called a non-foamed sheet or a solid sheet, etc.). Alternatively, the welded layer 21 can also be a foamed sheet, etc. Alternatively, the welded layer 21 can also be a sheet of fibrous material such as knitted fabric, woven fabric, or non-woven fabric.

[0036] The additional layer 22 is formed of a different material than the weld layer 21, or has a different structure. The additional layer 22 enhances the functions of the weld layer 21, or adds functions not present in the weld layer 21 to the sheet 20. The material constituting the additional layer 22 can be metal or the like, in addition to the materials described for the weld layer 21. The structure of the additional layer 22 can be any of the structures described for the weld layer 21. One surface of the additional layer 22 is the surface of the sheet 20 facing the side opposite to the linear transport member 40.

[0037] While the other surface of the welded layer 21 contacts the other surface of the additional layer 22, the welded layer 21 and the additional layer 22 are fixed together. The method of fixing the welded layer 21 and the additional layer 22 is not particularly limited; fixing by welding or bonding is preferable. For example, if at least one of the welded layer 21 and the additional layer 22 is a sheet with voids on its surface, such as a fiber material sheet or a foam sheet, then a resin material or adhesive can penetrate into the voids and be fixed. Thus, an anchoring effect is achieved, and the welded layer 21 and the additional layer 22 are firmly fixed together.

[0038] Here, we will describe the case where the weld layer 21 is a solid sheet made of resin and the additional layer 22 is a sheet of fiber material. We will also describe the case where the weld layer 21 and the additional layer 22 are welded together. That is, the resin of the weld layer 21, in a fluid state, enters between the fibers of the additional layer 22 and is then cured. Thus, the state in which the resin of the weld layer 21 enters between the fibers of the additional layer 22 is maintained, and the weld layer 21 and the additional layer 22 are firmly fixed together.

[0039] The weld layer 21 and the additional layer 22 are formed to be the same size (the same planar shape). Alternatively, the weld layer 21 and the additional layer 22 may be formed such that one is larger than the other. The weld layer 21 and the additional layer 22 fix the contacting area as a whole. Alternatively, the weld layer 21 and the additional layer 22 may fix only a portion of the contacting area.

[0040] The sheet 20 can also be a flexible component. For example, the weld layer 21 is a resin layer with a uniform solid cross-section made of a soft resin such as soft PVC, and the additional layer 22 is a non-woven fabric made of PET, thus making the sheet 20 a flexible component. For example, the sheet 20 can also have flexibility to follow the bending of the linear transmission component 40. The wiring component 10 can also be bent in the thickness direction in the portion where the sheet 20 is provided (the bending is such that the crease is along the main surface of the sheet 20). However, the sheet 20 can also be a component that cannot be bent in the thickness direction. The sheet 20 can also be a component that can be bent in the thickness direction without breaking. The sheet 20 can also be a component that cannot be bent in the thickness direction without breaking.

[0041] The retaining member 30 includes a retaining portion 31. A groove 34 and a protrusion 35 are formed in the retaining portion 31. The retaining portion 31 includes a bottom 32 and a plurality of sidewall portions 33. The bottom 32 and the plurality of sidewall portions 33 are formed in a flat plate shape. The plurality of sidewall portions 33 are formed to protrude from one surface of the bottom 32. The plurality of sidewall portions 33 extend parallel to each other. The portion enclosed by the bottom 32 and two sidewall portions 33 forms the groove 34. A protrusion 35 is formed at the front end of the sidewall portion 33. The protrusion 35 narrows the width of the opening of the groove 34.

[0042] The retaining member 30 is fixed to the sheet 20. The retaining member 30 is fused to the sheet 20. Here, the other side of the bottom 32 is in contact with the fusion layer 21. The other side of the bottom 32 is fused to the fusion layer 21. It is possible that the entire other side of the bottom 32 is fused to the fusion layer 21. It is also possible that only a portion of the other side of the bottom 32 is fused to the fusion layer 21.

[0043] At least one retaining member 30 is provided. Here, multiple retaining members 30 are provided on a sheet 20. One retaining member 30 is formed to be smaller than the sheet 20. The width dimension of the retaining member 30 is smaller than the width dimension of the sheet 20. The length dimension of the retaining member 30 is smaller than the length dimension of the sheet 20.

[0044] The multiple retaining members 30 may all be formed in the same shape. Some of the multiple retaining members 30 may also be formed in a different shape than the other retaining members 30. For example, the number of slots 34 in one of the multiple retaining members 30 may be different from the number of slots 34 in the other retaining members 30.

[0045] exist Figure 2 In the example shown, four slots 34 are provided in a retaining member 30. The number of slots 34 provided in a retaining member 30 can be any number, from one to three, or more than five.

[0046] The multiple linear transmission components 40 are linear components for transmitting electricity or light, etc. For example, the linear transmission component 40 can be a regular wire with a core wire and a sheath around the core wire, or it can be a shielded wire, cable, enameled wire, nickel-chromium alloy wire, optical fiber, etc. Each linear transmission component 40 has a transmission line body 41 and a sheath 42.

[0047] The transmission line body 41 is the part that transmits electricity or light. The transmission line body 41 is equivalent to the conductor core in an electrical wire, and also to the fiber core and sheath in an optical cable. Each sheathing layer 42 covers the transmission line body 41. The sheathing layers 42 are formed by extruding a resin material or the like around the transmission line body 41. The type of resin material is not particularly limited; PVC, PE, PP, PET, etc., can be used.

[0048] The linear transmission member 40, which transmits electricity, can be various signal lines or power lines. A portion of the linear transmission member 40 can be used as an antenna, coil, or other device for transmitting or receiving signals or power into or from space. Furthermore, the linear transmission member 40 can be a single linear object or a composite of multiple linear objects (such as stranded wire, cables that combine multiple linear objects and cover them with a sheath). When the linear transmission member 40 is a cable, the sheath is also included in the covering layer 42.

[0049] Imagine multiple linear transmission members 40 as components connecting parts in a vehicle to each other. The ends of the linear transmission members 40 extend from the sheet 20 and are located outside the sheet 20. The middle portion of the linear transmission member 40, excluding the ends, is disposed on the sheet 20. A connector C, for example, is provided at the end of the linear transmission member 40. The linear transmission member 40 is connected to the mating component via this connector C, thereby connecting the linear transmission member 40 to the mating component. That is, this wiring component 10 is used in vehicles, etc., as a wiring component 10 for electrically (or optically) connecting various components to each other. The ends of the linear transmission members 40 may also be located on the sheet 20. The connector housing of the connector C may also be fixed to the sheet 20.

[0050] Multiple linear transport members 40 include a first linear transport member 40A and a second linear transport member 40B. The first linear transport member 40A and the second linear transport member 40B are fixed relative to the sheet 20 in different ways. Specifically, the first linear transport member 40A is held by a retaining member 30. The first linear transport member 40A is housed in a groove 34. The first linear transport member 40A is housed relative to the groove 34 at a position closer to the bottom 32 of the protrusion 35. Thus, the protrusion 35 prevents the first linear transport member 40A from detaching from the groove 34. The second linear transport member 40B is fused to the sheet 20. A fusion layer 21 is in contact with the second linear transport member 40B. The fusion layer 21 is fused to the outermost covering layer 42 of the second linear transport member 40B.

[0051] The covering layer 42 of the first linear transmission member 40A is made of a first resin material. The welding layer 21 of the sheet 20 is made of a second resin material different from the first resin material. Here, the covering layer 42 of the second linear transmission member 40B is also made of the same second resin material as the welding layer 21. Here, the retaining member 30 is also made of the same second resin material as the welding layer 21. The combination of the first resin material and the second resin material can be any combination as long as they are different resin materials. For example, the first resin material can be PVC and the second resin material can be PE, etc. Alternatively, for example, the first resin material can be PE and the second resin material can be PVC, etc.

[0052] The retaining member 30 can also be a non-flexible member. The retaining member 30 can also be rigid, exhibiting elastic deformation such as the bottom 32 not being able to bend. For example, the sheet 20 and the covering layer 42 can be flexible members, while the retaining member 30 is a member harder than the sheet 20 and the covering layer 42. When the retaining member 30 and the weld layer 21 and the covering layer 42, which have different hardness than the retaining member 30, are formed from the same type of resin material, for example, they can be formed in the following way: That is, as a method to change the hardness of the resin material, methods including known methods can be used depending on the type of resin material. Specifically, for example, in the case of PVC, it is known that soft PVC and rigid PVC can be obtained by changing the amount of plasticizer added, etc. Rigid PVC is harder than soft PVC. By using soft PVC for the weld layer 21 and the covering layer 42 and rigid PVC for the retaining member 30, the retaining member 30 is harder than the sheet 20 and the covering layer 42. Furthermore, for example, in the case of PE resin material, it is known that low-density PE is softer than high-density PE. By using low-density PE in the weld layer 21 and the covering layer 42, and using high-density PE in the retaining member 30, the retaining member 30 is harder than the sheet 20 and the covering layer 42.

[0053] In the figures, the portion where the sheet 20 and the second linear transmission member 40B are fused together is designated as the fusion joint WP. Similarly, the portion where the sheet 20 and the retaining member 30 are fixed is designated as the fixing part FP. Here, the sheet 20 and the retaining member 30 are fused together. Therefore, the fixing part FP is also a fusion joint.

[0054] There is no particular limitation on the method for forming this welded state; various welding methods such as ultrasonic welding, heating and pressure welding, hot air welding, and high-frequency welding can be used. Furthermore, when a welded state is formed through these methods, the welded portion WP becomes a fixed welded state achieved by that method. Specifically, for example, if the welded portion WP is formed by ultrasonic welding, the welded portion WP becomes an ultrasonic welded portion.

[0055] Multiple welding sections WP are provided at intervals along the extension direction of the linear transport member 40. Alternatively, welding sections WP may be provided continuously along the extension direction of the linear transport member 40. Fixing sections FP are provided integrally along the width direction of the retaining member 30. Alternatively, multiple fixing sections FP may be provided at intervals along the width direction of the retaining member 30.

[0056] Holding members 30 are provided at multiple locations spaced apart along the length of the first linear transport member 40A. The holding members 30 at these multiple locations are fixed to a sheet 20. The holding members 30 are located to the side of the welded portion WP in the second linear transport member 40B. The holding members 30 may also be located to the side of a portion of the second linear transport member 40B where the welded portion WP is not provided.

[0057] One or more first linear transmission members 40A and second linear transmission members 40B are provided. The number of first linear transmission members 40A and second linear transmission members 40B can be any number; here, multiple first linear transmission members 40A and multiple second linear transmission members 40B are provided on both sides. Furthermore, in... Figure 1 and Figure 3 In the middle, there are four linear transmission components 40 with different paths, representing multiple linear transmission components 40.

[0058] The sheet 20 and the retaining member 30 hold the plurality of linear transmission members 40 in a side-by-side arrangement. Thus, the wiring member 10 is formed in a flat shape. Furthermore, the sheet 20 and the retaining member 30 hold the linear transmission members 40 in a state where they extend along a predetermined path. The path of the linear transmission members 40 is the path along which the linear transmission members 40 extend relative to the assembly object when the wiring member 10 is assembled to the assembly object (e.g., a vehicle). Therefore, when the wiring member 10 is assembled to a vehicle, etc., the linear transmission members 40 are easily positioned along a predetermined path within the vehicle, etc.

[0059] like Figure 1 As shown, the path of the linear transmission member 40 includes a bend 43 and a branch 44. The bend 43 is the portion where multiple linear transmission members 40 bend while remaining parallel. The branch 44 is the portion where a portion of the linear transmission members 40 branches off in a direction different from that of another portion of the linear transmission members 40. Here, a portion of the first linear transmission member 40A and the second linear transmission member 40B branches off from another portion of the first linear transmission member 40A and the second linear transmission member 40B. At the branch 44, one of the first linear transmission member 40A and the second linear transmission member 40B may also extend in a concentrated manner without branching. The first linear transmission member 40A and the second linear transmission member 40B may also branch. It is sufficient that at least one branch of one of the first linear transmission member 40A and the second linear transmission member 40B occurs at the branch 44.

[0060] Here, the sheet 20 is shaped to follow the path of the linear conveying member 40. The sheet 20 has a portion that bends according to the bending path of the linear conveying member 40. That is, the sheet 20 also bends at the bending portion 43. The sheet 20 has a portion that branches according to the branching path of the linear conveying member 40. That is, the sheet 20 also branches at the branching portion 44. The sheet 20 can also be formed into a large square, etc.

[0061] Crossings 45 and 46 are provided where multiple linear transmission members 40 intersect. Here, crossings 45 and 46 include branch crossings 45 and configuration-switching crossings 46. A branch crossing 45 is a section where one group of linear transmission members 40 intersects with another group of linear transmission members 40. A branch crossing 45 is provided at a branch section 44. A configuration-switching crossing 46 is a section where parallel linear transmission members 40 are intersected to change their arrangement order. A configuration-switching crossing 46 is provided at a parallel path section. A configuration-switching crossing 46 may also be provided at a branch section 44. The combination of the two linear transmission members 40 constituting crossings 45 and 46 can be any combination. At crossings 45 and 46, a first linear transmission member 40A may intersect with a second linear transmission member 40B. At crossings 45 and 46, the first linear transmission members 40A may intersect with each other, or the second linear transmission members 40B may intersect with each other.

[0062] Two retaining members 30 are provided on both sides of the bend 43. Multiple linear transmission members 40 bend between the two retaining members 30. Three retaining members 30 are provided at the location sandwiching the branch 44 and the branch intersection 45. Multiple linear transmission members 40 branch and cross between the three retaining members 30. Two retaining members 30 are provided on both sides of the configuration interchange intersection 46. Multiple linear transmission members 40 cross between the two retaining members 30.

[0063] The first linear transport member 40A and the second linear transport member 40B are parallel to each other in at least a portion of the sheet 20. Figure 1 In the example shown, the parallel section of the first linear transmission member 40A and the second linear transmission member 40B covers the entire section disposed on the sheet 20.

[0064] In the section where the first linear transmission member 40A and the second linear transmission member 40B run parallel, the number of first linear transmission members 40A may be greater, the number of second linear transmission members 40B may be greater, or the number of both may be the same. Figure 2 In the example shown, four first linear transmission members 40A and three second linear transmission members 40B run in parallel.

[0065] Multiple parallel second linear transmission members 40B are spaced apart from each other. The spacing between the second linear transmission members 40B is smaller than the diameter of the second linear transmission members 40B. The spacing between the second linear transmission members 40B can also be the same as or larger than the diameter of the second linear transmission members 40B.

[0066] The protrusion 35 is formed by thermally deforming the front end of the sidewall portion 33 of the groove 34. Figure 4 The formation of protrusion 35 is explained. Figure 4 This is an explanatory diagram showing the formation of protrusion 35.

[0067] Figure 4 The retaining member 30 indicated by the solid line is the retaining member 30 before the protrusion 35 is formed. Hereinafter, in order to distinguish it from the retaining member 30 and the side wall portion 33 after the protrusion 35 is formed, the retaining member 30 and the side wall portion 33 before the protrusion 35 is formed are sometimes referred to as retaining member 30S and side wall portion 33S.

[0068] No protrusion 35 is formed on the sidewall portion 33S of the retaining member 30S. In the retaining member 30S, the height of the sidewall portion 33S is greater than the height of the sidewall portion 33 of the retaining member 30. The sidewall portion 33 extends from the base end to the front end with the same degree of thickness. The inward-facing surface of the front end of the sidewall portion 33 can also be formed as an inclined surface for guiding the linear transfer member 40 to the groove 34. The width of the groove 34 at the front end of the sidewall portion 33 can also be wider than the width of the groove 34 on the bottom 32 side. The retaining member 30S is made of resin and is formed by extrusion molding or injection molding, etc. The type of resin material is not particularly limited and can be PVC, PE, PP, PET, etc. When the retaining member 30 is fused to the weld layer 21, the resin material is preferably the same as the resin material of the weld layer 21.

[0069] The first linear transmission member 40A is housed in the groove 34 of the retaining member 30S. In this state, the front end of the side wall portion 33S of the retaining member 30S undergoes thermal deformation, forming... Figure 4 The protrusion 35, represented by an imaginary line, serves as a retaining member 30. The front end of the side wall portion 33S is, for example, flattened by the melting head 80.

[0070] More specifically, the melting head 80 has a front end face capable of contacting the front ends of the plurality of sidewall portions 33S. The melting head 80 is a device heated by a heating unit such as a heater. The melting head 80 is heated to a temperature capable of softening the sidewall portions 33S. The heated melting head 80 is pressed against the front ends of the sidewall portions 33S. As a result, the front ends of the sidewall portions 33S are softened and flattened by the melting head 80. The softened and flattened front ends of the sidewall portions 33S extend upward toward the openings of the grooves 34 on both sides. As a result, protrusions 35 are formed that narrow the openings of the grooves 34. As a result, the first linear transmission member 40A is held in a state of being received in the grooves 34.

[0071] exist Figure 2 In the example shown, the protrusions 35 of adjacent sidewall portions 33 do not contact each other. Therefore, the groove 34 is slightly open between the protrusions 35. The protrusions 35 of adjacent sidewall portions 33 can also contact each other. The opening of the groove 34 can also be completely blocked by the protrusions 35. The protrusion amount of the protrusion 35 can be set, for example, as follows. That is, the protrusion amount of the protrusion 35 can be set such that when the linear transmission member 40 detaches from the groove 34 after the protrusion 35 is formed, the member 30 is kept plastically deformed. In other words, the protrusion amount of the protrusion 35 can be set such that the linear transmission member 40 is not easily detached from the groove 34 within the range of maintaining the elastic deformation of the member 30. Thus, the linear transmission member 40 is not easily detached from the groove 34.

[0072] In addition, Figure 4 In the example shown, the melting head 80 is abutted by the plurality of first linear transfer members 40A, which are all housed in the groove 34 and held by a holding member 30. Due to reasons such as the different destinations of the other ends of the first linear transfer members 40A, it is sometimes difficult to simultaneously arrange multiple first linear transfer members 40A in the groove 34. In this case, the plurality of first linear transfer members 40A can be divided into multiple groups and arranged in groups. For example, the melting head 80 can be formed by... Figure 4 The first group, consisting of two of the four linear transmission members 40 shown, and the second group, consisting of the other two linear transmission members 40, are sequentially arranged in the slot 34 at different operating times. Alternatively, in this case, the protrusions 35 can be formed in groups. Furthermore, in this case, the positions of the protrusions 35 in the first group and the second group of slots 34 can be staggered in the extending direction. That is, the front end of the sidewall portion 33S of the first group of linear transmission members 40, which is housed at a first position along the extending direction, is thermally deformed to become the protrusion 35 for the first group. Similarly, the front end of the sidewall portion 33S of the second group of linear transmission members 40, which is housed at a second position along the extending direction and staggered from the first position, is thermally deformed to become the protrusion 35 for the second group.

[0073] Furthermore, the welding operation between the sheet 20 and the second linear conveying member 40B, the fixing operation between the sheet 20 and the holding member 30, and the forming operation of the protrusion 35 can be performed in any order. Any two or three of these operations can also be performed simultaneously.

[0074] <Effects of Implementation Method 1, etc.>

[0075] According to the wiring component 10 configured as described above, the first linear transmission member 40A is held by a holding member 30 fixed to the sheet 20. Since a protrusion 35 is formed in the holding portion 31, the first linear transmission member 40A is less likely to fall out of the groove 34. Therefore, regardless of the type of linear transmission member 40, it can be easily fixed to the sheet 20. Furthermore, the second linear transmission member 40B is fused to the sheet 20. Thus, by fusing the linear transmission member 40 that can be fused to the sheet 20 to the sheet 20, and holding the linear transmission member 40 that is difficult to fused to the sheet 20 by the holding member 30, it is easily held to the sheet 20.

[0076] Furthermore, the retaining member 30 is fused to the sheet 20. Thus, the component that fixes the sheet 20 to the retaining member 30 can be omitted in the wiring component 10.

[0077] Furthermore, the first linear transport member 40A includes a coating layer 42 made of a resin material different from the resin material of the sheet 20. Therefore, the first linear transport member 40A, which is difficult to weld to the sheet 20, is fixed to the sheet 20 by the retaining member 30.

[0078] Furthermore, a protrusion 35 is formed by thermally deforming the front end of the side wall portion 33 of the groove 34. This simplifies the shape of the retaining member 30S before the protrusion 35 is formed. In addition, if the linear transmission member 40 is not removed from the groove 34 after the protrusion 35 is formed, the possibility of the linear transmission member 40 detaching from the groove 34 is suppressed by making the protrusion 35 larger.

[0079] Furthermore, the retaining members 30, which are provided at multiple locations spaced apart along the length of the first linear transmission member 40A, are fixed to a sheet 20. Thus, the multiple retaining members 30 are positioned by the sheet 20. Additionally, compared to the case where the retaining members 30 are provided throughout the entire first linear transmission member 40A, the area where the retaining members 30 are provided can be reduced.

[0080] [Implementation Method 2]

[0081] The wiring components involved in Embodiment 2 will be described. Figure 5This is a cross-sectional view showing the wiring component 110 according to Embodiment 2. Furthermore, in the description of this embodiment, the same reference numerals are used for the same components as those described so far, and their descriptions are omitted.

[0082] In the wiring assembly 110, the position of the retaining member 30 relative to the sheet 20 differs from that in the wiring assembly 110. Specifically, in the wiring assembly 110, multiple retaining members 30 are provided in the width direction of the sheet 20. Thus, as Figure 5 As shown, when the wiring component 110 bends about an axis along its length, the sheet 20 easily bends between the retaining members 30, and the bending of the retaining members 30 is suppressed. Therefore, when the wiring component 110 bends about an axis along its length, the linear transmission member 40 is less likely to detach from the retaining member 30.

[0083] exist Figure 5 In the example shown, two retaining members 30 are provided in the width direction of the sheet 20. Three or more retaining members 30 may also be provided in the width direction of the sheet 20. Additionally, in Figure 5 In the example shown, the two retaining members 30 are formed with the same shape. The two retaining members 30 can also be formed with different shapes. For example, the number of slots 34 in the two retaining members 30 can be different.

[0084] In addition, Figure 5 In the example shown, the second linear transmission member 40B is located between the two holding members 30. The two holding members 30 may also be arranged adjacent to each other so that the second linear transmission member 40B does not enter between the two holding members 30. Additionally, in Figure 5 In the example shown, the retaining member 30 is located at both sides of the sheet 20. Alternatively, the retaining member 30 may be located at one side edge of the sheet 20, and the second linear conveying member 40B may be located at the other side edge. Alternatively, the retaining member 30 may be located at the middle of the sheet 20, and the second linear conveying member 40B may be located at both sides of the sheet 20.

[0085] In a sheet 20, when the retaining members 30 are spaced apart at multiple locations along the extension direction of the first linear conveying member 40A, multiple retaining members 30 can be provided at all of the multiple locations along the width direction. Alternatively, multiple retaining members 30 can be provided at some of the multiple locations, and a single retaining member 30 can be provided at another location along the width direction.

[0086] [Variation Example]

[0087] So far, the case where wiring components 10 and 110 are equipped with the second linear transmission member 40B has been described, but this is not a necessary structure. Wiring components 10 and 110 may also be without the second linear transmission member 40B. For example, all the linear transmission members 40 in wiring components 10 and 110 may be held by the retaining member 30. Alternatively, for example, in wiring components 10 and 110, the linear transmission members 40 not held by the retaining member 30 may be fixed to the sheet 20 by a fixing method other than welding. As such a fixing method, for example, it may be bonding between the sheet 20 and the linear transmission member 40 via an adhesive or double-sided tape clamping member. Alternatively, for example, the linear transmission member may be pressed toward the sheet 20 by sewing, binding, single-sided tape, or a sheet different from the sheet 20.

[0088] So far, the case where the retaining member 30 is fused to the sheet 20 has been described, but this is not a necessary structure. The retaining member 30 and the sheet 20 can be fixed in any way. For example, the retaining member 30 and the sheet 20 can be bonded together using adhesive or double-sided tape. Alternatively, the retaining member 30 and the sheet 20 can be fixed together using a locking member such as a stapler. In this case, a portion of the bottom 32 can protrude laterally to form a flange, and the locking member can lock the sheet 20 in a manner that passes through the flange.

[0089] Furthermore, the description up to this point assumes that the protrusion 35 is formed by thermally deforming the front end of the sidewall portion 33 of the groove 34, but this is not a necessary structure. The protrusion 35 can also be formed in advance before the linear transmission member 40 is inserted. In this case, it is preferable that the retaining portion 31 can elastically deform to enlarge the opening of the groove 34 to a size that allows the linear transmission member 40 to be inserted. In addition, when the protrusion 35 is formed by thermally deforming the front end of the sidewall portion 33 of the groove 34, the protrusion 35 is formed to protrude to both sides of one sidewall portion 33, but this is not a necessary structure. The protrusion 35 can also be formed to protrude to one side of one sidewall portion 33. Such a protrusion 35 can be formed, for example, by bending the front end of the sidewall portion 33 upwards on one side of the groove 34 while it is softened by heating.

[0090] Furthermore, the description up to this point assumes that all slots 34 house the first linear transmission member 40A, but this is not a necessary configuration. It is also possible that some slots 34 do not house the first linear transmission member 40A. Additionally, the description up to this point assumes that all the multiple first linear transmission members 40A housed in the slots 34 have the same construction, but this is not a necessary configuration. A portion of the multiple first linear transmission members 40A housed in the slots 34 may have a different construction than another portion. For example, the multiple first linear transmission members 40A housed in the slots 34 may include linear transmission members of different diameters (thin and thick) and linear transmission members of different diameters.

[0091] Furthermore, the description up to this point assumes that one first linear transmission member 40A is housed in a single slot 34, but this is not a mandatory configuration. Multiple first linear transmission members 40A may also be housed in a single slot 34. Multiple first linear transmission members 40A may be arranged in the height direction (depth direction) within a single slot 34. Multiple first linear transmission members 40A may also be arranged in the width direction within a single slot 34. Multiple first linear transmission members 40A may also be arranged obliquely within a single slot 34. The number of first linear transmission members 40A housed in multiple slots 34 may also vary.

[0092] Furthermore, the description up to this point assumes that the covering layer 42 of all the first linear transmission members 40A is made of a resin material different from the resin material of the weld layer 21, but this is not a necessary structure. Some or all of the covering layers 42 of the first linear transmission members 40A may also be made of the same resin material as the weld layer 21. For example, a linear transmission member 40 that is difficult to weld to the weld layer 21, such as a stranded wire, can be held in the holding member 30 and used as the first linear transmission member 40A.

[0093] Furthermore, when the path of the first linear transmission member 40A has a branch 44, the number of first linear transmission members 40A running parallel before and after the branch 44 can be changed. In this case, the shape of the holding member 30 can be common before and after the branch 44. The second linear transmission member 40B, which is fused to the sheet 20 in the path on one side of the branch 44, can also be housed in the holding member 30 in the path on the other side of the branch 44.

[0094] Furthermore, the number of linear transmission members 40 in various wiring harnesses can vary depending on the vehicle model, grade, option, etc. In this case, the shape of the retaining member 30 can be common among the various wiring harnesses. Linear transmission members 40, which may or may not be provided depending on the type of wiring harness, can also be retained by a common retaining member 30.

[0095] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
