[0025] [Description of embodiments of this disclosure]

[0026] The embodiments of this disclosure are first described in detail.

[0027] The wiring components disclosed herein are as follows.

[0028] (1) A wiring component comprising: a plurality of linear transmission components; and a base component, wherein the plurality of linear transmission components are fixed to the base component via a fusion splice, the plurality of linear transmission components including a plurality of first linear transmission components and a plurality of second linear transmission components grouped according to a connection destination, the fusion splice including a first fusion splice and a second fusion splice different from the first fusion splice, the first fusion splice being a portion for fusion fixing the plurality of first linear transmission components in a parallel state to the base component, and the second fusion splice being a portion for fusion fixing the plurality of second linear transmission components in a parallel state to the base component.

[0029] According to this wiring component, multiple first linear transmission components and multiple second linear transmission components, grouped according to the connection destination, are fused and fixed to the base component via their respective first or second fusion splices. Therefore, in cases where there is a reduction, addition, or change in the type of multiple first or second linear transmission components, this can be addressed by changing the process of the first or second fusion splice. Furthermore, even if modifications are needed to the multiple first or second linear transmission components, this can be addressed by modifying the multiple first or second linear transmission components. Therefore, design changes or modifications to the wiring component can be easily accommodated.

[0030] (2) In the wiring component of (1), the first fusion splice and the second fusion splice may be separated.

[0031] Therefore, it is easy to weld multiple first linear transmission components and multiple second linear transmission components together without affecting each other.

[0032] (3) In the wiring component of (1), there may also be a boundary between the first fusion splice and the second fusion splice.

[0033] Therefore, it is easy to change the conditions and fuse multiple first linear transmission components with multiple second linear transmission components.

[0034] (4) In any of the wiring components in (1) to (3), the gap between the plurality of first linear transmission components and the plurality of second linear transmission components may be larger than the gap between the plurality of first linear transmission components and the gap between the plurality of second linear transmission components.

[0035] Therefore, it is easy to weld multiple first linear transmission components and multiple second linear transmission components separately.

[0036] (5) In the wiring component of (4), the gap between the plurality of first linear transmission components and the plurality of second linear transmission components may be larger than the gap between the plurality of first linear transmission components and the gap between the plurality of second linear transmission components in the end region of the plurality of first linear transmission components and the plurality of second linear transmission components.

[0037] Therefore, it is easy to set the positions of multiple first linear transmission components and multiple second linear transmission components according to the destination at the end.

[0038] (6) In any of (1) to (5) the wiring components may also be configured such that the plurality of first linear transmission components and the plurality of second linear transmission components are arranged on the base component in a manner to avoid crossing.

[0039] Therefore, it is not affected by the front-to-back relationship of the fusion splice caused by crossover, and can easily cope with design changes or modifications of wiring components.

[0040] (7) In any of (1) to (6) the wiring component may also be such that one end of the plurality of first linear transmission components is connected to a common one-end first connector, and the other end of the plurality of first linear transmission components is connected to a common other-end first connector, thereby the plurality of first linear transmission components constitute a first wiring module component, one end of the plurality of second linear transmission components is connected to a common one-end second connector, and the other end of the plurality of second linear transmission components is connected to a common other-end second connector, thereby the plurality of second linear transmission components constitute a second wiring module component, the second wiring module component being a component different from the first wiring module component.

[0041] In this configuration, multiple first linear transmission components constitute a first wiring module component, and multiple second linear transmission components constitute a second wiring module component that is different from the first wiring module component. Therefore, it is easy to make design changes to the multiple first linear transmission components and the multiple second linear transmission components separately, and also easy to make corrections.

[0042] Furthermore, the method for manufacturing the wiring component disclosed herein is as follows.

[0043] (8) A method for manufacturing a wiring component, wherein a plurality of first linear transmission components are welded together in a parallel manner to a base component, and a plurality of second linear transmission components are welded together in a parallel manner to the base component, and the operation of welding the plurality of first linear transmission components and the operation of welding the plurality of second linear transmission components are performed as independent operations with different welding timing or welding tools.

[0044] Therefore, it is easy to make design changes or modifications to the multiple first linear transmission components and multiple second linear transmission components respectively.

[0045] [Details of embodiments of this disclosure]

[0046] Hereinafter, specific examples of the wiring components and methods of manufacturing the wiring components of this disclosure will be described with reference to the accompanying drawings. It should be noted that this disclosure is not limited to these examples, and as shown in the claims, it is intended to include all modifications within the meaning and scope equivalent to the claims.

[0047] [Implementation Method]

[0048] The wiring component and its manufacturing method according to the embodiments will be described below. Figure 1 This is a top view showing the wiring component 10. Figure 2 This is a bottom view showing the wiring component 10.

[0049] <About wiring components>

[0050] The wiring component 10 will be described. The wiring component 10 includes a plurality of linear transmission components 20 and 30 and a base component 40.

[0051] The plurality of linear transmission components 20 and 30 include a plurality of first linear transmission components 20 and a plurality of second linear transmission components 30.

[0052] Imagine the first linear transmission member 20 and the second linear transmission member 30 as linear transmission members that connect components in a vehicle to each other. The first linear transmission member 20 and the second linear transmission member 30 extend along wiring paths corresponding to the locations of components that become the connection destinations.

[0053] More specifically, the linear transmission components 20 and 30 can be any linear components that transmit electricity or light. For example, the linear transmission components 20 and 30 can be general electrical wires having core wires 20a and 30a and surrounding coverings 20b and 30b (see reference). Figures 4 to 6 It can also be bare wire, shielded wire, stranded wire, enameled wire, nickel-chromium alloy wire, optical fiber, etc.

[0054] The linear transmission components 20 and 30 used for transmitting electricity can also be various signal lines or power lines. Parts of these linear transmission components can also be used as antennas, coils, etc., for transmitting or receiving signals or power into or from space.

[0055] In addition, the linear transmission components 20 and 30 can be a single linear object or a composite of multiple linear objects (twisted wire, cable that combines multiple linear objects and covers them with a sheath, etc.).

[0056] Here, we will explain the assumption that the first linear transmission member 20 is an electric wire and the second linear transmission member is an electric wire.

[0057] The plurality of first linear transmission components 20 and the plurality of second linear transmission components 30 are grouped according to their connection destinations. For example, the plurality of first linear transmission components 20 and the plurality of second linear transmission components 30 are grouped in such a way that they belong to a common group if they have the same connection destination, and to different groups if they have different connection destinations.

[0058] In this embodiment, one end of each of the plurality of first linear transmission members 20 is connected to a common one-end first connector 28, and the other end of each of the plurality of first linear transmission members 20 is connected to a common other-end first connector 29. Thus, a first wiring module component 20M can be configured to consist of a plurality of first linear transmission members 20 assembled from one-end first connector 28 and other-end first connector 29.

[0059] It should be noted that the connection of the first linear transmission member 20 to the connectors 28 and 29 is performed, for example, by mounting the terminals installed at the ends of the first linear transmission member 20 to the cavities formed in the housings of the connectors 28 and 29. The connection of the first linear transmission member 20 to the connectors 28 and 29 can be performed before, simultaneously with, or after the operation of fixing the first linear transmission member 20 to the base member 40.

[0060] Similarly, one end of each of the plurality of second linear transmission members 30 is connected to a common one-end second connector 38, and the other end of each of the plurality of second linear transmission members 30 is connected to a common other-end second connector 39. Thus, a second wiring module component 30M can be configured as a plurality of second linear transmission members 30 assembled by one-end second connector 38 and other-end second connector 39.

[0061] Each end of the plurality of first linear transmission members 20 and each end of the plurality of second linear transmission members 30 are not connected to a common connector. Therefore, the first wiring module component 20M and the second wiring module component 30M can be treated as physically separate individual components before or after being fixed relative to the base component 40.

[0062] It should be noted that the number of the plurality of first linear transmission components 20 is arbitrary, and the number of the plurality of second linear transmission components 30 is also arbitrary. In this embodiment, there are four first linear transmission components 20 and three second linear transmission components 30.

[0063] Furthermore, connectors 28, 29, 38, and 39 mentioned above are connectors that connect to different connection object connectors. These different connection object connectors can be connectors installed on different devices, or they can be different connectors installed on the same device.

[0064] The base member 40 is a member having a main surface for fixing a plurality of first linear transmission members 20 and a plurality of second linear transmission members 30. The base member 40 can be formed as a sheet or as a three-dimensional shape. The main surface can be a plane, a curved surface, a concave-convex surface, or a surface composed of a plane and other curved surfaces. For example, the base member 40 can also be a member with a flat, flat portion, and more specifically, a bendable sheet member. The base member 40 preferably has flexibility in the thickness direction.

[0065] The material constituting the substrate component 40 is not particularly limited, but it is preferably formed of a material containing resins such as PVC, PE, PET (polyethylene terephthalate), and PP (polypropylene). The substrate component 40 can be a solid sheet uniformly filled internally, or it can be a non-woven fabric sheet in which multiple fibers are wound without being woven. The substrate component 40 may also contain materials such as metal. The sheet component can be a single layer or multiple layers stacked. In the case of multiple layers stacked, for example, consider a sheet component stacked with resin layers and resin layers. More specifically, for example, regarding the sheet component, consider stacking a resin sheet uniformly filled internally and a non-woven fabric sheet. Alternatively, for example, the sheet component may be stacked with resin layers and metal layers.

[0066] Multiple first linear transmission members 20 and multiple second linear transmission members 30 are fixed to the main surface of the base member 40 via welding portions 26 and 36. Welding portions 26 and 36 include a first welding portion 26 for fixing the multiple first linear transmission members 20 to the base member 40 and a second welding portion 36 for fixing the multiple second linear transmission members 30 to the base member 40. The second welding portion 36 is configured to be a different welding portion from the first welding portion 26.

[0067] A plurality of first linear transmission members 20 are welded and fixed to the base member 40 in a parallel manner via the first welding section 26. A plurality of second linear transmission members 30 are welded and fixed to the base member 40 in a parallel manner via the second welding section 36.

[0068] More specifically, the base component 40 is formed into a shape that is elongated in one direction.

[0069] A plurality of first linear transmission members 20 extend from one end of the base member 40 along its length to the other end. The ends of the plurality of first linear transmission members 20 may extend toward either side of the base member 40 along its length, or toward the outer edge of the base member 40 along its length.

[0070] In this embodiment, the plurality of first linear transmission members 20 sequentially include a straight portion 21La at one end, a curved portion 21Ca at one end, a straight portion 21M in the middle, a curved portion 21Cb at the other end, and a straight portion 21Lb at the other end. The straight portion 21La at one end, the straight portion 21M in the middle, and the straight portion 21Lb at the other end are portions that extend in a straight line on the base member 40, while the curved portion 21Ca at one end and the curved portion 21Cb at the other end are portions that extend in a curved shape on the base member 40, specifically in an arc shape.

[0071] One end-bent portion 21Ca is connected to one end of the intermediate straight portion 21M, and one end-straight portion 21La is connected to the opposite side of the intermediate straight portion 21M relative to the one end-bent portion 21Ca. The rotation angle of the one end-bent portion 21Ca is set according to the angle at which the one end-straight portion 21La extends relative to the intermediate straight portion 21M. In this embodiment, the intermediate straight portion 21M is along the length direction of the base member 40, and the one end-straight portion 21La is orthogonal to the length direction of the base member 40. Therefore, the rotation angle of the one end-bent portion 21Ca is set to 90 degrees, and more specifically, it is set to form a 1 / 4 arc.

[0072] Similarly, the other end curved portion 21Cb is connected to the other end of the intermediate straight portion 21M, and the other end straight portion 21Lb is connected to the other end curved portion 21Cb on the opposite side of the intermediate straight portion 21M. The other end curved portion 21Cb bends in the same direction as the one end curved portion 21Ca, and the other end straight portion 21Lb extends in the same direction as the one end curved portion 21Ca.

[0073] Adjacent first linear transmission members 20 among the plurality of first linear transmission members 20 may or may not be in contact with each other. In this embodiment, adjacent first linear transmission members 20 among the plurality of first linear transmission members 20 are in contact with each other.

[0074] In addition, similar to the first linear transmission member 20, the plurality of second linear transmission members 30 respectively include, in the same manner as the first linear transmission member 20, a straight portion 31La on one end, a curved portion 31Ca on one end, a straight portion 31M in the middle, a curved portion 31Cb on the other end, and a straight portion 31Lb on the other end.

[0075] The middle straight portion 31M extends along the length direction of the base member 40, the one-end side curved portion 31Ca and the other-end side curved portion 31Cb bend to the same side as the one-end side curved portion 21Ca and the other-end side curved portion 21Cb, and the one-end side straight portion 31La and the other-end side straight portion 31Lb extend to the same side as the one-end side straight portion 21La and the other-end side straight portion 21Lb.

[0076] Adjacent second linear transmission members 30 among the plurality of second linear transmission members 30 may or may not be in contact with each other. In this embodiment, adjacent second linear transmission members 30 among the plurality of second linear transmission members 30 are in contact with each other.

[0077] Preferably, a plurality of first linear transmission members 20 and a plurality of second linear transmission members 30 are arranged on the base member 40 in a manner to avoid crossing.

[0078] For example, multiple intermediate straight sections 21M and multiple intermediate straight sections 31M are arranged side by side on the base member 40. The multiple intermediate straight sections 21M and multiple intermediate straight sections 31M may or may not be connected. In this embodiment, the intermediate straight section 21M on the side of the intermediate straight section 31M among the multiple intermediate straight sections 21M is connected to the intermediate straight section 31M on the side of the intermediate straight section 21M among the multiple intermediate straight sections 31M.

[0079] One-sided curved portion 31Ca is located on the outer periphery of one-sided curved portion 21Ca. In this embodiment, one end of the intermediate straight portion 31M extends to a position outside the middle straight portion 21M, and the one-sided curved portion 31Ca is positioned further outward than the one-sided curved portion 21Ca from the middle straight portion 21M. At this position, the one-sided curved portion 31Ca bends in the same direction as the one-sided curved portion 21Ca, thereby the one-sided curved portion 31Ca is located on the outer periphery of the one-sided curved portion 21Ca.

[0080] A gap is formed between the one-end side bend 31Ca and the one-end side bend 21Ca. That is, a gap larger than the gap between the multiple one-end side bends 31Ca and the multiple one-end side bends 21Ca is formed between the group of multiple one-end side bends 31Ca and the group of multiple one-end side bends 21Ca.

[0081] One-end straight sections 21La and 31La extend from each end of one-end curved sections 21Ca and 31Ca. Multiple one-end straight sections 21La and multiple one-end straight sections 31La run parallel to each other. Furthermore, a gap S is formed between the multiple one-end straight sections 21La and the multiple one-end straight sections 31La. That is, a gap larger than the gap between the multiple one-end straight sections 21La and the gap between the multiple one-end straight sections 31La is formed between the groups of multiple one-end straight sections 21La and the groups of multiple one-end straight sections 31La.

[0082] Therefore, in the end regions of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, the gap S between the group of the plurality of one-end straight sections 21La and the group of the plurality of one-end straight sections 31La is set to be larger than the gap between the plurality of one-end straight sections 21La and the gap between the plurality of one-end straight sections 31La.

[0083] Similarly, the other end curved portion 31Cb is located on the outer periphery of the other end curved portion 21Cb, and the other end straight portions 21Lb and 31Lb extend from their respective ends.

[0084] It should be noted that the path example of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 described above is just one example. For example, at least one end of the plurality of first linear transmission members 20 or the plurality of second linear transmission members 30 may extend in the same direction as the intermediate straight portion. Alternatively, one end of the plurality of second linear transmission members 30 may extend to the opposite side relative to one end of the plurality of first linear transmission members 20. Furthermore, more straight portions may be continuous with more curved portions, and the plurality of first linear transmission members 20 or the plurality of second linear transmission members 30 may be arranged along a more complex path.

[0085] Multiple first linear transmission components 20 are fixed to the base component 40 via a first weld 26, and multiple second linear transmission components 30 are fixed to the base component 40 via a second weld 36 that is different from the first weld 26.

[0086] It should be noted that welding refers to the process by which the resin contained in at least one of the first linear transport member 20 or the second linear transport member 30 and the matrix member 40 melts due to an increase in temperature, thereby adhering and fixing them tightly. That is, the welded portions 26 and 36 are portions that are welded and fixed by heat.

[0087] At this time, various welding methods can be employed to form the welded portions 26 and 36 by heating and welding, such as ultrasonic welding, heat and pressure welding, hot air welding, or high-frequency welding. Furthermore, when the welded portions 26 and 36 are formed by these methods, the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are fixed in a welded state based on this method. Specifically, for example, when the welded portions 26 and 36 are formed by ultrasonic welding, the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are in a state where the welded portions 26 and 36 are formed by ultrasonic welding.

[0088] In this embodiment, the welded portion 26 is a partial welded portion where the resin constituting the base member 40 and the resin coating constituting the first linear transmission member 20 are fixed together by ultrasonic welding. Similarly, the welded portion 36 is a partial welded portion where the resin constituting the base member 40 and the resin coating constituting the second linear transmission member 30 are fixed together by ultrasonic welding.

[0089] Furthermore, the second weld portion 36 differs from the first weld portion 26 in that it is a structure capable of welding the first weld portion 26 and the second weld portion 36 separately, rather than a structure where welding one of the first weld portion 26 and the second weld portion 36 necessitates welding the other. The ability to weld separately includes situations where welding can be performed at different times and situations where welding can be performed using different welding tools. For example, the first weld portion 26 and the second weld portion 36 are formed by clamping the first linear transmission member 20 or the second linear transmission member 30 to the base member using a welding head and anvil for ultrasonic welding and imparting ultrasonic vibration energy. In this case, the first weld portion 26 and the second weld portion 36 can be formed using different combinations of welding heads and anvils, or they can be formed at different times using the same combination of welding head and anvil.

[0090] Imagine that, in order to impart energy for melting under pressure, a first weld portion 26 and a second weld portion 36 are formed by sandwiching a first linear transport member 20 or a second linear transport member 30 between two welding tools and a base member 40. The two weld portions are, for example, a welding head and anvil for ultrasonic welding. Therefore, it is assumed that traces of welding tools remain between the first linear transport member 20 or the second linear transport member 30 and the base member 40. That is, at the location where the first linear transport member 20 or the second linear transport member 30 is fixed to the base member 40, there are welding tool traces 26a and 36a recessed in the first linear transport member 20 or the second linear transport member 30 on the side opposite to the base member 40 (see reference). Figure 1The portion of the welding tool marks (26b, 36b) recessed on the side opposite to the linear transmission members 20, 30 in the base member 40 is the first weld portion 26 or the second weld portion 36.

[0091] Since the first welded portion 26 and the second welded portion 36 are respectively configured as welded portions, traces remain of the formation of the first welded portion 26 and the second welded portion 36.

[0092] For example, in Figure 2 In this design, the first welded portion 26 and the second welded portion 36 are envisioned to be separated in such a way that the first welded portion 26 (and its welding tool mark 26b) welds the straight portion 21La at one end to the base member 40 and the second welded portion 36 (and its welding tool mark 36b) welds the straight portion 31La at one end to the base member 40.

[0093] For example, if the first weld portion 26 and the second weld portion 36 are formed in different regions at different times, then the first weld portion 26 and the second weld portion 36 are formed in separate positions. Alternatively, if the first weld portion 26 and the second weld portion 36 are formed in different regions that are separated from each other at the same time using different welding tools, then the first weld portion 26 and the second weld portion 36 are formed in separate positions.

[0094] In particular, the gap S between the straight portion 21La at one end of the first linear transmission member 20 and the straight portion 31La at one end of the second linear transmission member 30 is larger than the gaps between the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, thus facilitating the separation of the first weld portion 26 and the second weld portion 36. In this embodiment, the gap between the plurality of first linear transmission members 20 is 0, and the gap between the plurality of second linear transmission members 30 is also 0. It should be noted that the gaps between the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 may unavoidably exist due to the bending tendency of the linear transmission members 20 and 30 and the limits of the position alignment process.

[0095] For example, in Figure 2 In this context, it is envisioned that a boundary B exists between the first welded portion 26 (and its welding tool mark 26b) which is manifested as a first welded portion 26 that welds the intermediate straight portion 21M to the base member 40 and a second welded portion 36 (and its welding tool mark 36b) that welds the intermediate straight portion 31M to the base member 40.

[0096] Boundary B can be a mark on the outer edge of the part of the welding tool that contacts the base member 40, such as the edge mark of the contact surface of the welding head or anvil used for ultrasonic welding. It is assumed that even when the welding tool mark 26b of the first welding portion 26 and the welding tool mark 36b of the second welding portion 36 are arranged adjacently, their boundary B will remain as an edge mark of the welding tool. For example, if a group of multiple intermediate straight sections 21M and a group of multiple intermediate straight sections 31M are adjacent to each other, even if the welding tools used for welding both are pressed against the base member 40 in the adjacent area, the mark of the welding tool will remain at their boundary B.

[0097] <Example of manufacturing method for wiring components>

[0098] An example of the manufacturing method of the above-mentioned wiring component 10 will be described.

[0099] like Figure 3 As shown, a plurality of first linear transmission members 20 are disposed on the base member 40. The plurality of first linear transmission members 20 can be disposed on the base member 40 simultaneously, or the plurality of first linear transmission members 20 can be sequentially fused together from one end along the length direction and disposed on the base member 40.

[0100] Multiple first linear transmission components 20 are arranged in a parallel configuration, and these multiple first linear transmission components 20 are fused together to the base component 40. For example, as... Figure 4 As shown, welding is performed by using a pair of welding tools 50, 52 to clamp together a plurality of first linear transmission members 20 arranged side-by-side on the base member 40 and applying energy for welding. Thus, the plurality of first linear transmission members 20 are simultaneously welded and fixed to the base member 40 in a side-by-side configuration, forming first weld portions 26. The plurality of first weld portions 26 are formed at intervals along the length of the plurality of first linear transmission members 20. The plurality of first weld portions 26 can be formed sequentially or simultaneously along the length of the plurality of first linear transmission members 20.

[0101] Next, a plurality of second linear transmission members 30 are disposed on the base member 40. The plurality of second linear transmission members 30 can be disposed on the base member 40 simultaneously, or the plurality of second linear transmission members 30 can be sequentially fused together from one end along the length direction and disposed on the base member 40.

[0102] Multiple second linear transmission members 30 are arranged in a parallel configuration and then fused together to the base member 40. For example, ... Figure 5As shown, welding is performed by using a pair of welding tools 54 and 56 to clamp together a plurality of second linear transmission members 30 arranged side-by-side on the base member 40 and applying energy for welding. Thus, the plurality of second linear transmission members 30 are simultaneously welded and fixed to the base member 40 in a side-by-side configuration, forming second weld portions 36. The plurality of second weld portions 36 are formed at intervals along the length of the plurality of second linear transmission members 30. The plurality of second weld portions 36 can be formed sequentially or simultaneously along the length of the plurality of second linear transmission members 30.

[0103] When the number, material, or thickness of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 differ, the width or the shape of the contact surface may differ between the aforementioned welding tools 50, 52 and welding tools 54, 56. Furthermore, the welding conditions (e.g., welding time, target temperature, or pressure conditions) for forming the first welding portion 26 and the second welding portion 36 may differ.

[0104] By separating the first fusion joint 26 from the second fusion joint 36, multiple first linear transmission members 20 and multiple second linear transmission members 30 can be fused together under suitable conditions. Furthermore, by subdividing the multiple first linear transmission members 20 and multiple second linear transmission members 30 into bundles, they can be easily arranged in a side-by-side configuration.

[0105] In the above example, it is illustrated that the operation of welding multiple first linear transmission members 20 and the operation of welding multiple second linear transmission members 30 are performed as separate operations with different welding tools 50, 52 and welding tools 54, 56, and with different welding timings. Both can also be performed using the same welding tool.

[0106] In addition, such as Figure 6 As shown, welding tools 50 and 52 can also perform welding operations on multiple first linear transmission members 20 and welding operations on multiple second linear transmission members 30 at the same time as welding tools 54 and 56.

[0107] In this case, welding tools 50, 52 and welding tools 54, 56 can be arranged adjacent to each other. In this case, it is also contemplated that a gap may be formed between the first welding portion 26 and the second welding portion 36 due to a small gap or step between welding tools 50, 52 and welding tools 54, 56.

[0108] In addition, such as Figure 7As shown, when one end straight section 21La and one end straight section 31La are welded together, regardless of whether the two operations are performed at the same time or at different times, the welding tools 50, 52 and welding tools 54, 56 are configured separately. Therefore, it is considered that the first welding section 26 and the second welding section 36 are separated.

[0109] It should be noted that in the above embodiments and examples, an example is described in which the first weld portion 26 for welding the plurality of second linear transmission members 30 and the second weld portion 36 for welding the plurality of second linear transmission members 30 are located at the same position in the extending direction of these linear transmission members 20, 30. However, it is also possible to... Figure 8 As shown in the wiring member 110, the first fusion portion 126 corresponding to the first fusion portion 26 and the second fusion portion 136 corresponding to the second fusion portion 136 are staggered in the extension direction of the linear transmission members 20 and 30.

[0110] <Effects, etc.>

[0111] According to the wiring component 10 configured as described above and its manufacturing method, a plurality of first linear transmission components 20 and a plurality of second linear transmission components 30, grouped according to the connection destination, are welded and fixed to the base component 40 via their respective first fusion splice 26 or second fusion splice 36.

[0112] Therefore, in the event of reduction, addition, or change of wire type of multiple first linear transmission members 20 or multiple second linear transmission members 30, the problem can be addressed by changing the process involved in the first welding section 26 or the second welding section 36.

[0113] For example, such as Figure 9 As shown, a linear transmission member 20x is added to the plurality of first linear transmission members 20 predetermined in the initial stage. In this case, the welding tool or welding conditions for forming the second welding portion 36 are changed without changing the welding tool or welding conditions for forming the first welding portion 26. Therefore, design changes can be easily addressed by only partially changing the manufacturing apparatus, conditions, etc.

[0114] Furthermore, even if modifications are required for the multiple first linear transmission members 20 or the multiple second linear transmission members 30, they can be addressed through modifications to the multiple first linear transmission members 20 or the multiple second linear transmission members 30.

[0115] For example, such as Figure 10As shown, traces of welding multiple first linear transmission members 20 to a portion of multiple first weld portions 26 of the base member 40 are formed at a position 26F offset from the first linear transmission member 20. In this case, the welding operation of the multiple first linear transmission members 20 is not affected, and the welding operation of the multiple first linear transmission members 20 is repeated. In this way, by welding the multiple first linear transmission members 20 and the multiple second linear transmission members 30 separately, defects in one can be corrected separately, and the correction operation becomes easier compared to correcting the whole. Therefore, design changes or modifications to the wiring member 10 can be easily addressed.

[0116] Furthermore, since the first welded portion 26 and the second welded portion 36 are separated, it is easy to weld the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 together without affecting each other.

[0117] Furthermore, since there is a boundary B between the first welded portion 26 and the second welded portion 36, the conditions can be easily changed by using welding tools 50, 52 or welding tools 54, 56 or by changing the timing, and the multiple first linear transmission members 20 and the multiple second linear transmission members 30 can be welded together.

[0118] In addition, the gap S between the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 is larger than the gap between the plurality of linear transmission members and the gap between the plurality of linear transmission members, so it is easy to weld the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 respectively.

[0119] Furthermore, in the end regions of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, the gap S between the straight portion 21La (or the straight portion 21Lb) at one end of the plurality of first linear transmission members 20 and the straight portion 31La (or the straight portion 31Lb) at one end of the plurality of second linear transmission members 30 is larger than the gap between the straight portions 21La (or the straight portion 21Lb) at one end of the plurality of linear transmission members 20 and the gap between the straight portions 31La (or the straight portion 31Lb) at one end of the plurality of linear transmission members 30. Therefore, the positions of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 on the base member 40 can be easily set according to the destination of the ends of the linear transmission members 20 and 30.

[0120] Furthermore, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are arranged on the base member 40 in a manner to avoid crossing. Therefore, design changes or modifications can be made independently, and design changes or modifications to the wiring member 10 can be easily addressed.

[0121] Furthermore, one end of each of the plurality of first linear transmission members 20 is connected to a common one-side first connector 28, and the other end of each of the plurality of first linear transmission members 20 is connected to a common other-side first connector 29, thereby constituting a first wiring module component 20M. Additionally, one end of each of the plurality of second linear transmission members 30 is connected to a common one-side second connector 38, and the other end of each of the plurality of second linear transmission members 30 is connected to a common other-side second connector 39, thereby constituting a second wiring module component 30M that is different from the first wiring module component 20M. Therefore, it is easy to make design changes to the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, and it is also easy to make corrections.

[0122] Furthermore, multiple first linear transmission components 20 are welded to the base component 40 in a parallel configuration, and multiple second linear transmission components 30 are welded to the base component 40 in a parallel configuration. In this case, the two welding operations can be performed as welding at different times or as separate operations using different welding tools 50, 52, 54, and 56. Therefore, it is easy to make design changes or modifications to the multiple first linear transmission components 20 and the multiple second linear transmission components 30 respectively.

[0123] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
