[0024] [Description of embodiments of this disclosure]

[0025] First, the implementation schemes of this disclosure are illustrated.

[0026] The fusion splice disclosed herein is as follows.

[0027] (1) A welding sheet comprising: a substrate layer having a first surface and a second surface; a welding base portion partially laminated to the first surface of the substrate layer, capable of welding with a linear conveying member; and an adhesive base portion partially laminated to the second surface of the substrate layer, having a greater adhesive force with the adhesive member than with the substrate layer; a first interval and a second interval being provided along the extension direction of the substrate layer, wherein the first interval is an interval in which the welding base portion is laminated relative to the substrate layer, avoiding the lamination interval of the adhesive base portion, and the second interval is an interval in which the adhesive base portion is laminated relative to the substrate layer, avoiding the lamination interval of the welding base portion. By providing the adhesive base portion, good adhesion can be obtained. In addition, by providing the first interval and the second interval, the area where the welding base portion is provided and the area where the adhesive base portion is provided can be reduced, and the weight increase of the welding sheet can be suppressed. Furthermore, by the absence of the adhesive base portion in the first interval, good welding performance between the welding base portion in the first interval and the linear conveying member can be obtained.

[0028] (2) In the weld sheet of (1), the second surface of the substrate layer may be exposed in the first interval, and the first surface of the substrate layer may be exposed in the second interval. This exposes the substrate layer. Furthermore, the weld sheet can be thinner in the first interval, resulting in good weldability.

[0029] (3) In the weld sheet of (1) or (2), the lamination interval of the weld base portion relative to the substrate layer and the lamination interval of the adhesive base portion relative to the substrate layer may be staggered in a non-overlapping manner. This suppresses the increase in weight of the weld sheet. Furthermore, even if the size of the weld base portion along the extension direction of the substrate layer is small, the welding tool is less likely to come into contact with the adhesive base portion.

[0030] (4) In any of the welded pieces (1) to (3), the size of the second interval may be larger than the size of the first interval along the extension direction of the substrate layer. This increases the area suitable for bonding along the extension direction of the substrate layer.

[0031] (5) In any of the welded pieces in (1) to (4), the substrate layer may have two straight regions extending in mutually different directions and a connecting region connecting the two straight regions. The first interval is provided at the end of each of the two straight regions on the side of the connecting region, and the second interval is provided in the connecting region. When the linear conveying member is configured to bend from one of the two straight regions through the connecting region to the other of the two straight regions, the linear conveying member is welded to the welded base portion of the first interval, thereby easily maintaining a bent path.

[0032] (6) In any of the welded pieces in (1) to (5), the resin material used as the main raw material for the welded base portion and the resin material used as the main raw material for the adhesive base portion may be the same. This makes it easier to weld the linear conveying member to the adhesive base portion.

[0033] (7) In any of the welded sheets in (1) to (6), the substrate layer may be formed of a sheet of fibrous material, and the adhesive base portion may be formed of a sheet uniformly filled inside, the surface of the adhesive base portion being smoother than the surface of the substrate layer. Thus, the adhesive base portion can be easily provided.

[0034] (8) Furthermore, the wiring component of this disclosure includes: any one of the fusion splices (1) to (7); and a linear conveying member, which is fused to the fusion substrate portion in the first interval. By providing the adhesive substrate portion, good adhesion can be obtained. In addition, by providing the first interval and the second interval, the area where the fusion substrate portion is provided and the area where the adhesive substrate portion is provided can be reduced, and the increase in weight of the fusion splice can be suppressed. Furthermore, by the absence of the adhesive substrate portion in the first interval, good fusion between the fusion substrate portion in the first interval and the linear conveying member can be obtained.

[0035] [Details of the embodiments of this disclosure]

[0036] The following is a reference to the appendix. Figure 1 Specific examples of the fusion splice of this disclosure will be described below. It should be noted that this disclosure is not limited to these examples, and as indicated by the scope of the claims, it is intended to include all modifications within the same meaning and scope as the claims.

[0037] [Implementation Method 1]

[0038] The following describes the fusion splice according to Embodiment 1. Figure 1 This is a perspective view showing the weld sheet 10 according to Embodiment 1.

[0039] The weld sheet 10 includes a substrate layer 20, a weld base portion 30, and an adhesive base portion 40. The substrate layer 20 has a first surface 21 and a second surface 22. The first surface 21 and the second surface 22 face opposite sides. The substrate layer 20 is continuously disposed from a first end to a second end along the extending direction of the weld sheet 10. The extending direction of the substrate layer 20 is the extending direction of the weld sheet 10. The weld base portion 30 is partially laminated onto the first surface 21 of the substrate layer 20. The weld base portion 30 is laminated along the extending direction of the substrate layer 20 at multiple locations with gaps. The adhesive base portion 40 is partially laminated onto the second surface 22 of the substrate layer 20. The adhesive base portion 40 is laminated along the extending direction of the substrate layer 20 at multiple locations with gaps. The surface of the weld sheet 10 with the weld base portion 30 is designated as the first surface of the weld sheet 10, and the surface with the adhesive base portion 40 is designated as the second surface of the weld sheet 10.

[0040] The substrate layer 20 holds the weld base portion 30 and the adhesive base portion 40. The substrate layer 20 may have a different structure than the weld base portion 30 and the adhesive base portion 40, or may be formed of a different material than the weld base portion 30 and the adhesive base portion 40. The substrate layer 20 may enhance the functions of the weld base portion 30 or the adhesive base portion 40, or add functions not present in the weld base portion 30 and the adhesive base portion 40 to the weld sheet 10.

[0041] Here, the substrate layer 20 has a single-layer structure. For example, the substrate layer 20 is formed of a sheet of fibrous material. The fibrous material sheet is an aggregate of fibers. The fibrous material sheet can be a structure in which yarns of fibers are regularly aggregated (e.g., textiles, knitted fabrics, etc.), or it can be a structure in which fibers are randomly aggregated (e.g., nonwoven fabrics, etc.). On the surface of the fibrous material sheet, the fibers constituting the fibrous material sheet can be napped. Through this napping, the surface of the fibrous material sheet adheres to the adhesive member 90 (see reference 90). Figure 4 The adhesive properties of the fiber material sheet decrease. For example, the substantial contact area between the surface of the fiber material sheet and the adhesive component decreases, or the fibers scatter from the fiber material sheet, thus reducing the adhesive properties. If the fiber material sheet is, for example, a nonwoven fabric or a textile or knitted fabric formed from multifilament yarns, the fibers constituting the fiber material sheet are prone to pilling on the surface of the fiber material sheet.

[0042] The main raw material constituting the substrate layer 20 is not particularly limited and can be appropriately set. For example, if the substrate layer 20 is a fiber material sheet, the fiber constituting the fiber material sheet can be a natural fiber or a chemical fiber such as a synthetic fiber. As a synthetic fiber, any type of fiber is acceptable, for example, it can be a polyester synthetic fiber such as polyethylene terephthalate (PET), a polyolefin synthetic fiber such as polyethylene (PE) or polypropylene (PP), or a polyamide synthetic fiber such as nylon.

[0043] The welding base portion 30 is capable of bonding with the linear conveying member 60 (see reference). Figure 2 The fusion-welded portion. The fusion-welded base portion 30 is more easily bonded to the covering layer 62 of the linear conveying member 60 (see reference 20). Figure 3 Welding. The main raw material of the welding substrate 30 may be the same as or different from the main raw material of the substrate layer 20. The main raw material of the welding substrate 30 may be a resin material, preferably a thermoplastic resin material. Preferably, the resin material of the welding substrate 30 is softened and welded to the linear conveying member 60. The type of resin material is not particularly limited, and polyvinyl chloride (PVC), PE, PP, PET, etc. may be used. For example, the welding substrate 30 may be composed of a resin material that is compatible with the resin material of the covering layer 62.

[0044] The structure of the welding substrate portion 30 is not particularly limited and can be appropriately designed. For example, the welding substrate portion 30 can be a sheet that is filled internally (also called a non-foamed sheet or a solid sheet, etc.). Alternatively, for example, the welding substrate portion 30 can also be considered as a foamed sheet, etc.

[0045] The adhesive substrate portion 40 is the portion with a greater adhesive force to the adhesive member 90 than the substrate layer 20. For example, because the surface of the adhesive substrate portion 40 is smoother than the surface of the substrate layer 20, resulting in less fuzzing, the adhesive force between the adhesive substrate portion 40 and the adhesive member 90 is greater than that between the substrate layer 20 and the adhesive member 90. The construction of the adhesive substrate portion 40 can be the same as or different from that of the welded substrate portion 30. For example, the adhesive substrate portion 40 can be formed from a solid sheet or a foam sheet. The main raw material of the adhesive substrate portion 40 can be the same as or different from that of the substrate layer 20. The main raw material of the adhesive substrate portion 40 can be the same as or different from that of the welded substrate portion 30. The main raw material of the adhesive substrate portion 40 can be a resin material, preferably a thermoplastic resin material. The type of resin material is not particularly limited, and PVC, PE, PP, PET, etc., can be used.

[0046] A welding substrate portion 30 is fixed to the first surface 21 of the substrate layer 20, and an adhesive substrate portion 40 is fixed to the second surface 22 of the substrate layer 20. The method of fixing the substrate layer 20 to the welding substrate portion 30 and the method of fixing the substrate layer 20 to the adhesive substrate portion 40 are not particularly limited, but can be fixed by welding or bonding. For example, if the first surface 21 or the second surface 22 of the substrate layer 20 is a sheet with voids on its surface, such as a fibrous material sheet, the resin material or adhesive of the welding substrate portion 30 and the adhesive substrate portion 40 can enter the voids and be fixed. Thus, the so-called anchoring effect is achieved, and the substrate layer 20, the welding substrate portion 30, and the adhesive substrate portion 40 are firmly fixed.

[0047] Here, the fusion-bonded substrate portion 30 and the adhesive substrate portion 40 are solid sheets made of resin, and the substrate layer 20 is a sheet of fibrous material. Furthermore, the fusion-bonded substrate portion 30 and the adhesive substrate portion 40 are fused to the substrate layer 20. The resin in the fusion-bonded substrate portion 30 and the adhesive substrate portion 40, in a fluid state, enters between the fibers of the substrate layer 20 and is then cured. Thus, maintaining a state where the resin in the fusion-bonded substrate portion 30 and the adhesive substrate portion 40 enters between the fibers of the substrate layer 20 at equal intervals, the fusion-bonded substrate portion 30 and the adhesive substrate portion 40 are firmly fixed to the substrate layer 20.

[0048] The welding substrate portion 30 and the adhesive substrate portion 40 are formed to be smaller than the substrate layer 20. The area where the welding substrate portion 30 and the substrate layer 20 contact is entirely fixed. Alternatively, only a portion of the area where the welding substrate portion 30 and the substrate layer 20 contact is fixed. The area where the adhesive substrate portion 40 and the substrate layer 20 contact is entirely fixed. Alternatively, only a portion of the area where the adhesive substrate portion 40 and the substrate layer 20 contact is fixed.

[0049] The planar shapes of the welding substrate portion 30 and the adhesive substrate portion 40 are square. However, the planar shapes of the welding substrate portion 30 and the adhesive substrate portion 40 can also be other than square. The welding substrate portion 30 and the adhesive substrate portion 40 are formed to the same size. Alternatively, one of the welding substrate portion 30 and the adhesive substrate portion 40 may be formed to be larger than the other.

[0050] Along the extension direction, the weld sheet 10 has intervals where the lamination states of the weld base portion 30 and the adhesive base portion 40 relative to the substrate layer 20 differ. As intervals where the lamination states of the weld base portion 30 and the adhesive base portion 40 relative to the substrate layer 20 differ, four intervals may be generated, corresponding to combinations of the presence or absence of lamination of the weld base portion 30 relative to the substrate layer 20 and the presence or absence of lamination of the adhesive base portion 40 relative to the substrate layer 20. In this disclosure, these four intervals are referred to as the first interval S1 (refer to...). Figure 2 ), second interval S2 (refer to) Figure 2 ), third interval S3 (refer to) Figure 6 ) and the fourth interval S4 (refer to Figure 9 ).

[0051] The first interval S1 is the interval in which the welded substrate portion 30 is laminated relative to the substrate layer 20, but the adhesive substrate portion 40 is not laminated. The first interval S1 is the interval in which the welded substrate portion 30 is laminated relative to the substrate layer 20, avoiding the adhesive substrate portion 40. The second interval S2 is the interval in which the adhesive substrate portion 40 is laminated relative to the substrate layer 20, but the welded substrate portion 30 is not laminated. The second interval S2 is the interval in which the adhesive substrate portion 40 is laminated relative to the substrate layer 20, avoiding the welded substrate portion 30. The third interval S3 is the interval in which both the welded substrate portion 30 and the adhesive substrate portion 40 are not laminated relative to the substrate layer 20. The fourth interval S4 is the interval in which both the welded substrate portion 30 and the adhesive substrate portion 40 are laminated relative to the substrate layer 20.

[0052] A welding base portion 30 appears on the first surface of the welding sheet 10. The portion on the first surface of the welding sheet 10 where the welding base portion 30 may appear is either the first interval S1 or the fourth interval S4. The portion on the first surface of the welding sheet 10 where the welding base portion 30 may not appear is either the second interval S2 or the third interval S3. The first surface of the welding sheet 10 has irregularities in the thickness direction. The welding base portion 30 appears on the convex portion of the first surface of the welding sheet 10. The welding base portion 30 does not appear on the concave portion of the first surface of the welding sheet 10.

[0053] An adhesive substrate portion 40 appears on the second surface of the welded sheet 10. The portion on the second surface of the welded sheet 10 where the adhesive substrate portion 40 may appear is the second interval S2 or the fourth interval S4. The portion on the second surface of the welded sheet 10 where the adhesive substrate portion 40 may not appear is the first interval S1 or the third interval S3. The second surface of the welded sheet 10 has irregularities in the thickness direction. The adhesive substrate portion 40 appears on the convex portion of the second surface of the welded sheet 10. The adhesive substrate portion 40 does not appear on the concave portion of the second surface of the welded sheet 10.

[0054] The weld patch 10 is provided with at least the first interval S1 and the second interval S2 of the above four intervals along the extension direction. A third interval S3 and a fourth interval S4 may be provided along the extension direction of the weld patch 10, or they may not be provided.

[0055] Here, the lamination intervals of the welding substrate portion 30 relative to the substrate layer 20 and the lamination intervals of the adhesive substrate portion 40 relative to the substrate layer 20 are staggered in a non-overlapping manner. That is, the fourth interval S4 is not provided in the welding sheet 10. Moreover, here, from the first end along the extension direction of the substrate layer 20 toward the second end, the first interval S1 and the second interval S2 are alternately continuous without gaps. That is, only the first interval S1 and the second interval S2 are provided in the welding sheet 10 along the extension direction of the substrate layer 20, and the third interval S3 and the fourth interval S4 are not provided. Therefore, in the welding sheet 10, the concave and convex shapes of the first surface and the second surface are completely reversed. In the welding sheet 10, the welding substrate portion 30 is provided at both the first end and the second end along the extension direction of the substrate layer 20. Alternatively, in the welding sheet 10, the adhesive substrate portion 40 is provided at both the first end and the second end along the extension direction of the substrate layer 20. Alternatively, in the weld sheet 10, a weld base portion is provided at the first end along the extension direction of the substrate layer 20, and an adhesive base portion 40 is provided at the second end.

[0056] Here, on the first surface 21 of the substrate layer 20, no other layers are laminated in the portion where the welding base portion 30 is not provided. Therefore, in the second interval S2 of the weld sheet 10, the first surface 21 of the substrate layer 20 is exposed. On the first surface of the weld sheet 10, the substrate layer 20 appears in the portion different from the welding base portion 30 (here, a recess in the first surface of the weld sheet 10). Here, on the second surface 22 of the substrate layer 20, no other layers are laminated in the portion where the adhesive base portion 40 is not provided. Therefore, in the first interval S1 of the weld sheet 10, the second surface 22 of the substrate layer 20 is exposed. On the second surface of the weld sheet 10, the substrate layer 20 appears in the portion different from the adhesive base portion 40 (here, a recess in the second surface of the weld sheet 10).

[0057] exist Figure 1 In the example shown, the welding substrate portion 30 and the adhesive substrate portion 40 are integrally disposed from one end to the other along the width direction of the substrate layer 20. The welding substrate portion 30 may also be disposed only in a portion along the width direction of the substrate layer 20. Similarly, the adhesive substrate portion 40 may also be disposed only in a portion along the width direction of the substrate layer 20. For example, the welding substrate portion 30 and the adhesive substrate portion 40 may not be disposed at both ends along the width direction of the substrate layer 20, but only in the middle portion. In this case, at each end along the width direction of the substrate layer 20, the third interval S3 is continuous from one end to the other along the width direction of the substrate layer 20.

[0058] The weld strip 10 can be a flexible component. For example, the weld base portion 30 and the adhesive base portion 40 are solid sheets made of soft resin such as soft PVC, and the substrate layer 20 is made of non-woven fabric such as PET, thus the weld strip 10 is a flexible component. For example, the weld strip 10 can have the flexibility to follow the bending of the linear conveying member 60. That is, the wiring member 70 can also be bent in the thickness direction (the crease bends along the main surface of the weld strip 10).

[0059] <Wiring Component 70>

[0060] Figure 2 This is an explanatory diagram showing the situation where a linear conveying member 60 is fused to a welding piece 10 to form a wiring member 70. Figure 3 It is along Figure 2 A cross-sectional view along line III-III.

[0061] The wiring component 70 includes a fusion splice 10 and a linear conveying component 60. The linear conveying component 60 is disposed on a first surface of the fusion splice 10 such that it extends along the extension direction of the substrate. The linear conveying component 60 is fused with the fusion substrate portion 30 in a first interval S1.

[0062] The linear conveying member 60 is a linear member that transmits electricity or light, etc. The linear conveying member 60 includes one or more. Here, multiple linear conveying members 60 are included. The weld patch 10 is integrally formed into a flat shape. Multiple linear conveying members 60 are fixed to the weld patch 10 in a manner arranged in the width direction of the weld patch 10, and the wiring member 70 remains in a flat shape.

[0063] The linear transmission member 60 is envisioned as a component that connects parts in a vehicle to each other. For example, a connector C is provided at the end of the linear transmission member 60. The linear transmission member 60 is connected to the opposite component by connecting to a connector provided on the opposite component via this connector C. In other words, this wiring member 70 is used as a wiring member 70 for electrically (or optically) connecting various components to each other in a vehicle or the like. The connector C may also be fixed to the fusion splice 10.

[0064] The path of the linear conveyor 60 is set according to the position of the component that becomes the connection destination. The linear conveyor 60 is fixed to the welding strip 10, and remains in a state along a wiring path corresponding to the position of the component that becomes its respective connection destination. The linear conveyor 60 may also be fixed to the welding strip 10 as a branch line branching from the main line. The welding strip 10 may also be formed in a shape where the fixed branch line branches from the fixed main line. The linear conveyor 60 may also have a curved path on the welding strip 10. The planar shape of the welding strip 10 may also be a shape that is curved according to the curved path of the linear conveyor 60.

[0065] The linear transmission member 60 includes a transmission line body 61 and a sheathing layer 62. The transmission line body 61 transmits electricity or light, etc. The transmission line body 61 is equivalent to the core wire in an electric wire or the core and cladding in an optical fiber. The sheathing layer 62 covers the transmission line body 61. For example, the sheathing layer 62 is obtained by extruding resin or the like around the transmission line body 61. For example, the linear transmission member 60 can be a general electric wire with a core wire and a sheathing layer 62 around the core wire, or it can be a shielded wire, stranded wire, enameled wire, nickel-chromium wire, optical fiber, etc.

[0066] The linear transmission member 60 for transmitting electricity can be various signal lines or various power lines. A part of the linear transmission member 60 for transmitting electricity can also be used as an antenna, coil, etc., to transmit or receive signals or electricity into or from space.

[0067] In addition, the linear transmission member 60 can be a single linear object or a composite of multiple linear objects (such as stranded wire, cable obtained by combining multiple linear objects and covering them with an outer sheath).

[0068] The linear conveying member 60 and the welding piece 10 are fixed by welding together the covering layer 62 and the welding base portion 30. The part where the linear conveying member 60 and the welding piece 10 are welded together is called the welding section WP. At the welding section WP, the materials of the covering layer 62 and the welding base portion 30 can be melted and mixed. In this case, the resin material of the main raw material of the covering layer 62 can be the same as the resin material of the main raw material of the welding base portion 30. Alternatively, only one of the resin material of the covering layer 62 and the resin material of the welding base portion 30 can be melted and bonded to the other side of the member.

[0069] The welding of the linear conveying member 60 and the welding plate 10 can be performed by a welding machine having a heating and pressurizing mechanism. This welding machine is not particularly limited, but may be, for example, an ultrasonic welding machine UW. The ultrasonic welding machine UW includes a welding head H and an anvil A as the heating and pressurizing mechanism. The welding head H is a member located on one side relative to the two members being welded and imparts ultrasonic vibrations to the part to be welded. The anvil A is located on the opposite side of the welding head H relative to the two members being welded. The two members being welded are clamped by the welding head H and the anvil A while receiving ultrasonic vibrations from the welding head H. Frictional heat is generated in the part to be welded by this ultrasonic vibration, thereby heating the part to be welded. At this time, from the viewpoint of efficiently heating the part to be welded (here, efficiently generating frictional heat based on ultrasonic vibration in the part to be welded), it is preferable that the distance between the heating member (here, the welding head H) and the part to be welded is close. In this example, the heating member (here, the welding head H) is located on the side of the welding plate 10. In this example, since no adhesive base portion 40 is provided in the first interval S1, the welding head H can be brought close to the fusion base portion 30 accordingly. As a result, good fusion between the linear conveying member 60 and the fusion piece 10 can be obtained.

[0070] exist Figure 2 In the example shown, only a portion of the weld base portion 30 extending along the substrate layer 20 is the weld portion WP. The weld base portion 30 has portions that are weld portions WP along the extension direction of the substrate layer 20 and portions that are not weld portions WP. This is because the weld head H is smaller than the weld base portion 30. In the case where the first interval S1 and the second interval S2 are continuous along the extension direction of the substrate layer 20 without any gaps, as in this example, by making the weld head H smaller than the weld base portion 30, the possibility of interference between the adhesive base portion 40 and the weld head H can be reduced. It should be noted that it is also possible for the entire weld base portion 30 extending along the extension direction of the substrate layer 20 to be the weld portion WP.

[0071] <Fixing Structure of Wiring Component 70>

[0072] Figure 4 This is an exploded perspective view showing the fixed wiring component 70. Figure 5 This is a cross-sectional view showing the fixing structure of the wiring member 70.

[0073] The fixing object 80 of the wiring member 70 can be a component mounted on a vehicle, such as an interior component like the roof trim, an exterior component like a body panel, or the vehicle body itself. The fixing object 80 has a mounting surface 82. The wiring member 70 is mounted on the mounting surface 82. Alternatively, the mounting surface 82 can be flat, and the wiring member 70 can be mounted flat along the flat surface. Or, the mounting surface 82 can be curved, and the wiring member 70 can be mounted curved along the curved surface. Alternatively, a step can exist on the mounting surface 82, and the wiring member 70 can be mounted over the step.

[0074] An adhesive member 90 is provided on the configuration surface 82. The adhesive member 90 is not particularly limited, but may be, for example, a double-sided adhesive tape such as butyl tape. The adhesive member 90 is provided continuously along the extension direction of the weld sheet 10. The adhesive member 90 may also be provided intermittently along the extension direction of the weld sheet 10. In this case, the adhesive member 90 may be provided partially at the position of the configuration second interval S2.

[0075] The wiring member 70 is positioned on the placement surface 82 with the second surface of the adhesive base portion 40 in the weld bond 10 facing the adhesive member 90. The wiring member 70 is fixed to the fixing object 80 by bonding the adhesive base portion 40 to the adhesive member 90. Since the adhesive force between the adhesive base portion 40 and the adhesive member 90 is greater than that of the substrate layer 20, good adhesion is achieved. The portion of the second surface of the weld bond 10 where the adhesive base portion 40 is not located (e.g., the first section S1) may or may not contact the adhesive member 90.

[0076] <Effect>

[0077] Based on the fusion splice 10 configured as described above and the wiring member 70 equipped with the fusion splice 10, good adhesion can be obtained by providing the adhesive base portion 40. Furthermore, by providing the first interval S1 and the second interval S2, the areas where the fusion base portion 30 and the adhesive base portion 40 are provided can be reduced, thus suppressing the increase in weight of the fusion splice 10. Additionally, by eliminating the adhesive base portion 40 in the first interval S1, good fusion adhesion between the fusion base portion 30 in the first interval S1 and the linear conveying member 60 can be obtained.

[0078] Furthermore, the lamination areas of the welding substrate portion 30 relative to the substrate layer 20 and the lamination areas of the adhesive substrate portion 40 relative to the substrate layer 20 are staggered in a non-overlapping manner. As a result, the increase in weight of the welding sheet 10 is suppressed. In addition, even if the size of the welding substrate portion 30 along the extension direction of the substrate layer 20 is small, the welding tool is less likely to come into contact with the adhesive substrate portion 40.

[0079] Furthermore, in the first interval S1, the second surface 22 of the substrate layer 20 is exposed, and in the second interval S2, the first surface 21 of the substrate layer 20 is exposed. This allows the substrate layer 20 to be exposed. Additionally, in the first interval S1, the thickness of the weld patch 10 can be reduced, resulting in good weldability.

[0080] Furthermore, the resin material used as the main raw material for the welding substrate 30 is the same as the resin material used as the main raw material for the adhesive substrate 40. This makes it easier to weld the linear conveying member 60 to the adhesive substrate 40.

[0081] Furthermore, the substrate layer 20 is formed of a sheet of fibrous material, and the adhesive base portion 40 is formed of a sheet that is similarly filled internally. The surface of the adhesive base portion 40 is smoother than the surface of the substrate layer 20. As a result, the adhesive base portion 40 can be easily installed.

[0082] [Implementation Method 2]

[0083] The welding piece involved in Embodiment 2 will be described. Figure 6 This is a side view showing the fusion splice 110 and the wiring member 170 having the fusion splice 110 according to Embodiment 2. Figure 7 This is a side view showing the fixing structure of the wiring member 170 equipped with the fusion splice 110. It should be noted that in the following description of various embodiments and modifications, the same reference numerals are used for the same components as those described so far, and their descriptions are omitted.

[0084] The weld patch 110 differs from the weld patch 10 described above in that the size of the second interval S2 is larger than the size of the first interval S1 along the extension direction of the substrate layer 20. In the weld patch 110, by making the size of the second interval S2 larger than the size of the first interval S1 along the extension direction of the substrate layer 20, the area suitable for bonding can be increased along the extension direction of the substrate layer 20.

[0085] The dimensions of the first interval S1 and the second interval S2 that satisfy this condition are not particularly limited and can be appropriately set. For example, the dimension of the first interval S1 along the extension direction of the substrate layer 20 can be any value between 10 mm and 30 mm. For example, the dimension of the second interval S2 along the extension direction of the substrate layer 20 can be any value between 50 mm and 150 mm. Furthermore, for example, the difference between the dimension of the second interval S2 along the extension direction of the substrate layer 20 and the dimension of the first interval S1 along the extension direction of the substrate layer 20 can be any value between 50 mm and 150 mm. Furthermore, for example, the dimension of the second interval S2 along the extension direction of the substrate layer 20 can be any value between 2 and 10 times the dimension of the first interval S1 along the extension direction of the substrate layer 20. Furthermore, for example, the dimension of the first interval S1 along the extension direction of the substrate layer 20 can be smaller than the dimension of the substrate layer 20 along the width direction of the substrate layer 20, and the dimension of the second interval S2 along the extension direction of the substrate layer 20 can be the same as or larger than the dimension of the substrate layer 20 along the width direction of the substrate layer 20.

[0086] Furthermore, the weld patch 110 differs from the weld patch 10 described above in that it has a third section S3. The third section S3 is located between the first section S1 and the second section S2. Therefore, in the weld patch 110, similar to the weld patch 10, the lamination intervals of the weld base portion 30 relative to the substrate layer 20 and the lamination intervals of the adhesive base portion 40 relative to the substrate layer 20 are staggered in a non-overlapping manner. That is, the weld patch 110 does not have a fourth section S4. Additionally, by providing the third section S3, even if the size of the weld base portion 30 along the extension direction of the substrate layer 20 is small, it is less likely that the welding tool will come into contact with the adhesive base portion 40. Furthermore, as... Figure 6 As shown in the example, it becomes easy to make the entire welded portion WP along the extension direction of the substrate layer 20 in the welded base portion 30 a welded portion.

[0087] The size of the third section S3 along the extension direction of the substrate layer 20 is not particularly limited and can be appropriately set. For example, the size of the third section S3 along the extension direction of the substrate layer 20 can be smaller than the size of the first section S1 and the second section S2 along the extension direction of the substrate layer 20.

[0088] [Implementation Method 3]

[0089] The welding piece involved in Embodiment 3 will be described. Figure 8 This is a top view showing the fusion splice 210 and the wiring member 270 having the fusion splice 210 according to Embodiment 3.

[0090] The weld strip 210 differs from the weld strip 10 described above in that the substrate layer 20 has a curved path. Specifically, the substrate layer 20 has two straight regions 23 and 24 extending in mutually opposite directions and a connecting region 25 connecting the two straight regions 23 and 24. Figure 8 In the example shown, the extension directions of the two straight lines 23 and 24 are orthogonal, but they can also intersect at angles other than orthogonal. A first interval S1 is provided at the end of the connecting region 25 of each of the two straight lines 23 and 24. A second interval S2 is provided in the connecting region 25. It should be noted that the connecting region 25 is the area where the extended regions of the two straight lines 23 and 24 overlap. Typically, the connecting region 25 is parallelogram-shaped. Figure 8 As shown in the example, when the extension directions of the two straight regions 23 and 24 are orthogonal, the connecting region 25 is square in shape.

[0091] According to the welding piece 210 in this example, when the linear conveying member 60 is bent from one of the two straight regions 23 and 24 through the connecting region 25 to the other of the two straight regions 23 and 24, the linear conveying member 60 is welded to the welding base portion 30 of the first interval S1 provided at the end of the connecting region 25 side of each of the two straight regions 23 and 24, thereby easily maintaining the bent path.

[0092] [Variation Example]

[0093] Figure 9 This is a side view showing the fusion splice 310 and the wiring member 370 having the fusion splice 310 in the modified example.

[0094] A fourth section S4 is provided in the weld joint 310. The fourth section S4 is located between the first section S1 and the second section S2. The size of the fourth section S4 along the extension direction of the substrate layer 20 is not particularly limited and can be appropriately set. For example, the size of the fourth section S4 along the extension direction of the substrate layer 20 can be smaller than the size of the first section S1 and the second section S2 along the extension direction of the substrate layer 20. By providing the fourth section S4 in the weld joint 310, the weld joint 310 is less likely to bend between the first section S1 and the second section S2. When the fourth section S4 is provided in the weld joint 310, the fourth section S4 can also be welded to the linear conveying member 60, but it is preferable not to weld it.

[0095] Furthermore, the weld patch 310 has a first connecting portion 50 connecting the weld base portion 30. The first connecting portion 50 is made of the same material as the weld base portion 30, but is thinner than the weld base portion 30. In this case, the first surface 21 of the substrate layer 20 is completely covered by the weld base portion 30 and the first connecting portion 50. The first connecting portion 50 appears on the first surface of the weld patch 310, but the substrate layer 20 does not appear. In the first surface of the weld patch 310, the portion where the first connecting portion 50 appears is recessed compared to the portion where the weld base portion 30 appears. In the first surface of the weld patch 310, the portion where the first connecting portion 50 appears is either the second interval S2 or the third interval S3.

[0096] Additionally, the weld sheet 310 has a second connecting portion 52 that connects to the adhesive substrate portion 40. The second connecting portion 52 is made of the same material as the adhesive substrate portion 40, but is thinner than the adhesive substrate portion 40. In this case, the second surface 22 of the substrate layer 20 is completely covered by the adhesive substrate portion 40 and the second connecting portion 52. The second connecting portion 52 appears on the second surface of the weld sheet 310, but the substrate layer 20 does not. On the second surface of the weld sheet 310, the portion where the second connecting portion 52 appears is recessed compared to the portion where the adhesive substrate portion 40 appears. The portion on the second surface of the weld sheet 310 where the second connecting portion 52 appears is either a first interval S1 or a third interval S3.

[0097] Figure 10 This is a side view showing a modified example of the wiring member 70.

[0098] exist Figure 10 In the modified example of the wiring member 470 shown, a wire-like conveying member 60 is fused to both sides of the fusion splice 10. Similar to the wiring member 70, the wire-like conveying member 60 is fused to the fusion substrate portion 30 on the first side of the fusion splice 10. The wire-like conveying member 60 is fused to the adhesive substrate portion 40 on the second side of the fusion splice 10. This adhesive substrate portion 40 may have the same material and structure as the fusion substrate portion 30.

[0099] The linear conveying member 60 fused to the welding substrate portion 30 and the linear conveying member 60 fused to the adhesive substrate portion 40 are staggered along the width direction of the weld sheet 10. The linear conveying member 60 fused to the welding substrate portion 30 is located at one end along the width direction of the weld sheet 10. The linear conveying member 60 fused to the adhesive substrate portion 40 is located at the other end along the width direction of the weld sheet 10.

[0100] Figure 11 This is a side view showing the stack of wiring components and their fixing structure.

[0101] exist Figure 11In the example shown, three wiring components 70, 70A, and 470 are stacked to form a stack of wiring components. One of the three wiring components 70, 70A, and 470, wiring component 70, is identical to the aforementioned wiring component 70. The other wiring component 470 of the three wiring components 70, 70A, and 470 is identical to the aforementioned wiring component 470. The remaining wiring component 70A of the three wiring components 70, 70A, and 470 is different from the aforementioned wiring components 70, 170, 270, 370, and 470. No adhesive base portion 40 is provided on the weld patch 10A of wiring component 70A. In weld patch 10A, a weld base portion 30 is continuously provided along the extension direction of the substrate layer 20 from the first end to the second end on the first surface of the substrate layer 20. A wire-shaped conveying component 60 is welded to the first surface of weld patch 10A in wiring component 70A. In wiring component 70A, the wire-shaped conveying component 60 is not fused to the second side of the fusion splice 10A. In wiring component 70A, the second side 22 of the substrate layer 20 is exposed.

[0102] Three wiring components 70 are overlapped in the order of wiring component 70, wiring component 470, and wiring component 70A. The adhesive base portion 40 of the wiring component 70 faces the fixed object 80. The substrate layer 20 of the wiring component 70A faces the outer surface.

[0103] The linear conveying member 60 of the three wiring components 70, 70A, and 470 is located between the fusion splice 10 of the wiring component 70 and the fusion splice 10A of the wiring component 70A, and is protected by these fusion splices 10 and 10A. As in this example, the wiring component 470, on which the linear conveying member 60 is fused to both sides of the fusion splice 10, can also be provided as an intermediate layer of a stack of three or more wiring components.

[0104] In addition, it has been stated so far that the substrate layer 20 has a single-layer structure, but this is not a necessary structure. The substrate layer 20 can also have a multi-layer structure. In the case where the substrate layer 20 has a multi-layer structure, at least the second surface 22 of the substrate layer 20 may be composed of a sheet of fibrous material.

[0105] It should be noted that the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
