Mode for Carrying Out the Invention

[0011] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0012] The wiring member of the present disclosure is as follows.

[0013] (1) A wiring member including a plurality of linear transmission members and a base member to which the plurality of linear transmission members are fixed via a fusion bonding portion, the plurality of linear transmission members including a plurality of first linear transmission members and a plurality of second linear transmission members grouped according to connection destinations, the fusion bonding portion including a first fusion bonding portion and a second fusion bonding portion different from the first fusion bonding portion, the first fusion bonding portion being a portion for fusion bonding and fixing the plurality of first linear transmission members to the base member in a parallel state, and the second fusion bonding portion being a portion for fusion bonding and fixing the plurality of second linear transmission members to the base member in a parallel state.

[0014] According to this wiring member, a plurality of first linear transmission members and a plurality of second linear transmission members grouped according to connection destinations are fusion bonded and fixed to the base member via separate first fusion bonding portions or second fusion bonding portions. Therefore, when there is a reduction, addition, or wire type change in the plurality of first linear transmission members or the plurality of second linear transmission members, it can be dealt with by changing the process related to the first fusion bonding portion or the second fusion bonding portion. Also, even if repair is required for the plurality of first linear transmission members or the plurality of second linear transmission members, it can be dealt with by repairing the plurality of first linear transmission members or the plurality of second linear transmission members. Therefore, it is possible to easily cope with design changes or repairs of the wiring member.

[0015] (2) The wiring member of (1), wherein the first fusion part and the second fusion part may be separated from each other.

[0016] Thereby, a plurality of first linear transmission members and a plurality of second linear transmission members can be easily fused without affecting each other.

[0017] (3) The wiring member of (1), wherein a boundary may exist between the first fusion part and the second fusion part.

[0018] Thereby, a plurality of first linear transmission members and a plurality of second linear transmission members can be easily fused under different conditions.

[0019] (4) The wiring member according to any one of (1) to (3), wherein the gap between the plurality of first linear transmission members and the plurality of second linear transmission members may be larger than the gaps between the plurality of first linear transmission members and the gaps between the plurality of second linear transmission members.

[0020] Thereby, a plurality of first linear transmission members and a plurality of second linear transmission members can be easily fused separately.

[0021] (5) The wiring member of (4), wherein in the terminal regions of the plurality of first linear transmission members and the plurality of second linear transmission members, the gap between the plurality of first linear transmission members and the plurality of second linear transmission members may be larger than the gaps between the plurality of first linear transmission members and the gaps between the plurality of second linear transmission members.

[0022] Thereby, it is easy to set the positions of the plurality of first linear transmission members and the plurality of second linear transmission members according to the destinations of the terminals.

[0023] (6) The wiring member according to any one of (1) to (5), wherein the plurality of first linear transmission members and the plurality of second linear transmission members may be arranged on the base member so as to avoid intersection.

[0024] As a result, it is possible to easily cope with design changes or repairs of the wiring member without being affected by the order of fusion due to crossing or the like.

[0025] (7) Any one of the wiring members from (1) to (6), wherein one end of each of the plurality of first linear transmission members is connected to a common first connector on one end side, and each of the other ends of the plurality of first linear transmission members is connected to a common second connector on the other end side. Thus, the plurality of first linear transmission members are configured as a first wiring module component, and one end of each of the plurality of second linear transmission members is connected to a common first connector on one end side, and each of the other ends of the plurality of second linear transmission members is connected to a common second connector on the other end side. Thus, the plurality of second linear transmission members may be configured as a second wiring module component that is a separate component from the first wiring module component.

[0026] In this case, the plurality of first linear transmission members are configured as a first wiring module component, and the plurality of second linear transmission members are configured as a second wiring module component that is a separate component from the first wiring module component. Therefore, it is easy to separately design and modify the plurality of first linear transmission members and the plurality of second linear transmission members.

[0027] Also, the manufacturing method of the wiring member of the present disclosure is as follows.

[0028] (8) A manufacturing method of a wiring member, wherein a plurality of first linear transmission members are fused to a base member in parallel in a batch, a plurality of second linear transmission members are fused to the base member in parallel in a batch, and the operation of fusing the plurality of first linear transmission members and the operation of fusing the plurality of second linear transmission members are performed as separate operations with different fusing timings or fusing tools.

[0029] As a result, it is easy to separately design and modify the plurality of first linear transmission members and the plurality of second linear transmission members.

[0030] [Details of Embodiments of the Present Disclosure] Specific examples of the wiring member and the manufacturing method of the wiring member of the present disclosure will be described below with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0031] [Embodiment] Hereinafter, the wiring member and the manufacturing method of the wiring member according to the embodiment will be described. FIG. 1 is a plan view showing the wiring member 10, and FIG. 2 is a bottom view showing the wiring member 10.

[0032] [Regarding the wiring member] The wiring member 10 will be described. The wiring member 10 includes a plurality of linear transmission members 20 and 30 and a base member 40.

[0033] The plurality of linear transmission members 20 and 30 include a plurality of first linear transmission members 20 and a plurality of second linear transmission members 30.

[0034] The first linear transmission member 20 and the second linear transmission member 30 are assumed to be linear transmission members that connect components in a vehicle. The first linear transmission member 20 and the second linear transmission member 30 extend along a wiring route according to the position of the component to be connected and the like.

[0035] More specifically, the linear transmission members 20 and 30 may be any linear members that transmit electricity, light, or the like. For example, the linear transmission members 20 and 30 may be general electric wires having core wires 20a and 30a and coatings 20b and 30b around the core wires (see FIGS. 4 to 6), or may be bare conductors, shielded wires, twisted wires, enameled wires, nichrome wires, optical fibers, or the like.

[0036] As the linear transmission members 20 and 30 that transmit electricity, various signal lines and various power lines may be used. A part of the linear transmission members that transmit electricity may be used as an antenna, a coil, or the like that sends or receives signals or power to or from space.

[0037] In addition, each of the linear transmission members 20 and 30 may be a single linear object or a composite of a plurality of linear objects (such as a twisted wire or a cable in which a plurality of linear objects are gathered and covered with a sheath).

[0038] Here, an explanation is given assuming that the first linear transmission member 20 is an electric wire and the second linear transmission member is an electric wire.

[0039] The plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are grouped according to the connection destination. For example, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 belong to a common group if the connection destinations are the same, and are grouped so as to belong to different groups if the connection destinations are different.

[0040] In the present embodiment, each of the one ends of the plurality of first linear transmission members 20 is connected to a common one-end side first connector 28, and each of the other ends of the plurality of first linear transmission members 20 is connected to a common other-end side first connector 29. Thereby, the plurality of first linear transmission members 20 can be configured as a first wiring module component 20M assembled by the one-end side first connector 28 and the other-end side first connector 29.

[0041] Note that the connection of the first linear transmission member 20 to the connectors 28 and 29 is made, for example, by attaching terminals attached to the end of the first linear transmission member 20 to 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 may be made before, simultaneously with, or after the operation of fixing the first linear transmission member 20 to the base member 40.

[0042] Similarly, one end of each of the plurality of second linear transmission members 30 is connected to a common first end-side second connector 38, and the other end of each of the plurality of second linear transmission members 30 is connected to a common second end-side second connector 39. Thus, the plurality of second linear transmission members 30 can be configured as a second wiring module component 30M grouped by the first end-side second connector 38 and the second end-side second connector 39.

[0043] 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 handled as physically separated separate components before being fixed to the base member 40 or after being removed.

[0044] Note that the number of the plurality of first linear transmission members 20 is arbitrary, and the number of the plurality of second linear transmission members 30 is also arbitrary. In this embodiment, the number of the plurality of first linear transmission members 20 is four, and the number of the plurality of second linear transmission members 30 is three.

[0045] Also, the connectors 28, 29, 38, and 39 are connectors that are connected to different destination connectors. The different destination connectors may be connectors provided on different devices respectively, or different connectors provided on the same device.

[0046] The base member 40 is a member having a main surface to which the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are fixed. The base member 40 may be formed in a sheet shape or in a three-dimensional shape. The main surface may be a flat surface, a curved surface, an uneven surface, or a surface formed by combining a flat surface and other curved surfaces, etc. For example, the base member 40 may be a member having a flat flat portion, and more specifically, a bendable sheet member. The base member 40 preferably has flexibility that can be easily bent in the thickness direction.

[0047] The material constituting the base member 40 is not particularly limited, but the base member 40 is preferably formed of a material containing a resin such as PVC, PE, PET (polyethylene terephthalate), or PP (polypropylene). The base member 40 may be a solid sheet material with a uniformly filled interior, or may be a non-woven fabric sheet in which a plurality of fibers are intertwined without being woven. The base member 40 may also contain a material such as metal. The sheet member may be a single layer or may be a plurality of layers laminated. When a plurality of layers are laminated, for example, it is conceivable that the sheet member is formed by laminating a resin layer and a resin layer. More specifically, for example, it is conceivable that the sheet member is formed by laminating a resin sheet material with a uniformly filled interior and a non-woven fabric sheet. Also, for example, it is conceivable that the sheet member is formed by laminating a resin layer and a metal layer.

[0048] A plurality of first linear transmission members 20 and a plurality of second linear transmission members 30 are fixed to the main surface of the base member 40 via fusing portions 26, 36. The fusing portions 26, 36 include a first fusing portion 26 that fixes the plurality of first linear transmission members 20 to the base member 40 and a second fusing portion 36 that fixes the plurality of second linear transmission members 30 to the base member 40. The second fusing portion 36 is a fusing portion different from the first fusing portion 26.

[0049] By the first fusing portion 26, the plurality of first linear transmission members 20 are fused and fixed to the base member 40 in a parallel state. By the second fusing portion 36, the plurality of second linear transmission members 30 are fused and fixed to the base member 40 in a parallel state.

[0050] More specifically, the base member 40 is formed in a shape that is long in one direction.

[0051] The plurality of first linear transmission members 20 extend from one end side in the longitudinal direction of the base member 40 toward the other end side. The ends of the plurality of first linear transmission members 20 may extend toward either side portion in the longitudinal direction of the base member 40 or toward the edge facing outward in the longitudinal direction at each end in the longitudinal direction of the base member 40.

[0052] In this embodiment, each of the plurality of first linear transmission members 20 includes, in this order, a first end straight portion 21La, a first end bent portion 21Ca, an intermediate straight portion 21M, a second end bent portion 21Cb, and a second end straight portion 21Lb. The first end straight portion 21La, the intermediate straight portion 21M, and the second end straight portion 21Lb are portions that extend linearly on the base member 40, and the first end bent portion 21Ca and the second end bent portion 21Cb are portions that extend in a curved shape, here, in an arc shape, on the base member 40.

[0053] The first end bent portion 21Ca is connected to one end side of the intermediate straight portion 21M, and the first end straight portion 21La is connected to the opposite side of the intermediate straight portion 21M with respect to the first end bent portion 21Ca. The turning angle of the first end bent portion 21Ca is set according to the angle at which the first end straight portion 21La extends with respect to the intermediate straight portion 21M. In this embodiment, the intermediate straight portion 21M is along the longitudinal direction of the base member 40, and the first end straight portion 21La is orthogonal to the longitudinal direction of the base member 40. Therefore, the turning angle of the first end bent portion 21Ca is 90 degrees, more specifically, set to form a quarter arc.

[0054] Similarly to the above, the second end bent portion 21Cb is connected to the other end side of the intermediate straight portion 21M, and the second end straight portion 21Lb is connected to the opposite side of the intermediate straight portion 21M with respect to the second end bent portion 21Cb. The second end bent portion 21Cb bends in the same direction as the first end bent portion 21Ca, and the second end straight portion 21Lb extends on the same side as the first end bent portion 21Ca.

[0055] Among the plurality of first linear transmission members 20, adjacent ones may or may not be in contact with each other. In this embodiment, adjacent ones among the plurality of first linear transmission members 20 are in contact with each other.

[0056] Also, similar to the first linear transmission member 20, each of the plurality of second linear transmission members 30 includes, in this order, a first end straight portion 31La, a first end bent portion 31Ca, an intermediate straight portion 31M, a second end bent portion 31Cb, and a second end straight portion 31Lb, similar to the first linear transmission member 20.

[0057] The intermediate straight portion 31M extends along the longitudinal direction of the base member 40, the one - end - side bent portion 31Ca and the other - end - side bent portion 31Cb are bent to the same side as the one - end - side bent portion 21Ca and the other - end - side bent 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.

[0058] Among the plurality of second linear transmission members 30, adjacent ones may or may not be in contact. In the present embodiment, adjacent ones among the plurality of second linear transmission members 30 are in contact.

[0059] Preferably, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are arranged on the base member 40 so as to avoid intersection.

[0060] For example, the plurality of intermediate straight portions 21M and the plurality of intermediate straight portions 31M are arranged in parallel on the base member 40. The plurality of intermediate straight portions 21M and the plurality of intermediate straight portions 31M may or may not be in contact. In the present embodiment, among the plurality of intermediate straight portions 21M, those on the side of the intermediate straight portion 31M and those on the side of the intermediate straight portion 21M among the plurality of intermediate straight portions 31M are in contact.

[0061] The one - end - side bent portion 31Ca is located on the outer peripheral side of the one - end - side bent portion 21Ca. In the present embodiment, one end of the intermediate straight portion 31M extends outside one end of the intermediate straight portion 21M, and the one - end - side bent portion 31Ca is arranged at a position farther from the intermediate straight portion 21M than the one - end - side bent portion 21Ca on the outer side of the intermediate straight portion 21M. At this position, by bending the one - end - side bent portion 31Ca in the same direction as the one - end - side bent portion 21Ca, the one - end - side bent portion 31Ca is located on the outer peripheral side of the one - end - side bent portion 21Ca.

[0062] A gap is formed between the one - end - side bent portion 31Ca and the one - end - side bent portion 21Ca. That is, a gap larger than the gaps of the plurality of one - end - side bent portions 31Ca and the gaps of the plurality of one - end - side bent portions 21Ca is formed between the group of the plurality of one - end - side bent portions 31Ca and the group of the plurality of one - end - side bent portions 21Ca.

[0063] One - end - side straight portions 21La and 31La extend from the respective ends of the one - end - side bent portions 21Ca and 31Ca. The plurality of one - end - side straight portions 21La and the plurality of one - end - side straight portions 31La are parallel to each other. Also, a gap S is formed between the plurality of one - end - side straight portions 21La and the plurality of one - end - side straight portions 31La. That is, a gap larger than the gaps of the plurality of one - end - side straight portions 21La and the gaps of the plurality of one - end - side straight portions 31La is formed between the group of the plurality of one - end - side straight portions 21La and the group of the plurality of one - end - side straight portions 31La.

[0064] Therefore, in the terminal regions of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, the group of the plurality of one - end - side straight portions 21La, the group of the plurality of one - end - side straight portions 31La, and the gap S are set larger than the gaps of the plurality of one - end - side straight portions 21La and the gaps of the plurality of one - end - side straight portions 31La.

[0065] Similarly, the other - end - side bent portion 31Cb is located on the outer peripheral side of the other - end - side bent portion 21Cb, and the other - end - side straight portions 21Lb and 31Lb extend from their respective ends.

[0066] Note that the path examples of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are just examples. 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. Also, for any end of the plurality of first linear transmission members 20, any end of the plurality of second linear transmission members 30 may extend to the opposite side. Further, a larger number of straight portions and a larger number of curved portions may be continuous, 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.

[0067] The plurality of first linear transmission members 20 are fixed to the base member 40 via the first fusion portion 26, and the plurality of second linear transmission members 30 are fixed to the base member 40 by a second fusion portion 36 different from the first fusion portion 26.

[0068] Note that fusion bonding refers to the state where at least one of the resin included in, for example, the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 is melted by a temperature increase and adhered and fixed. That is, the fusion-bonded portions 26 and 36 are portions that are fusion-bonded and fixed by heat.

[0069] At this time, as the means for forming the fusion-bonded portions 26 and 36 by fusion bonding due to a temperature increase, various fusion-bonding means such as ultrasonic fusion bonding, heat and pressure fusion bonding, hot air fusion bonding, or high-frequency fusion bonding can be adopted. Further, when the fusion-bonded portions 26 and 36 are formed by these means, the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are in a state of being fusion-bonded and fixed by that means. Specifically, for example, when the fusion-bonded portions 26 and 36 are formed by ultrasonic fusion bonding, the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are in the state of the fusion-bonded portions 26 and 36 by ultrasonic fusion bonding.

[0070] In the present embodiment, the fusion-bonded portion 26 is a partial fusion-bonded portion where the resin constituting the base member 40 and the resin constituting the coating of the first linear transmission member 20 are fixed by ultrasonic fusion bonding. Further, the fusion-bonded portion 36 is a partial fusion-bonded portion where the resin constituting the base member 40 and the resin constituting the coating of the second linear transmission member 30 are fixed by ultrasonic fusion bonding.

[0071] Further, the fact that the second fusion part 36 is separate from the first fusion part 26 means that the first fusion part 26 and the second fusion part 36 can be fused separately, and it is not configured such that it is essential to fuse one of the first fusion part 26 and the second fusion part 36 in order to fuse the other. Being able to be fused separately includes the cases where they can be fused at different timings and the cases where they can be fused with different fusing tools for fusion. For example, the first fusion part 26 and the second fusion part 36 are formed by sandwiching the first linear transmission member 20 or the second linear transmission member 30 and the base member between a horn and an anvil for ultrasonic fusion and applying ultrasonic vibration energy. In this case, it is conceivable that the first fusion part 26 and the second fusion part 36 are formed by different combinations of horns and anvils, and it is also conceivable that they are formed at different timings by the same combination of horn and anvil.

[0072] In order to apply energy for melting in a pressurized state, it is assumed that the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are sandwiched between two fusing tools, whereby the first fusion part 26 and the second fusion part 36 are formed. The two fusion parts are, for example, a horn and an anvil for ultrasonic fusion. For this reason, it is conceivable that traces of the fusing tool remain on the first linear transmission member 20 or the second linear transmission member 30 and the base member 40. That is, at the location where the first linear transmission member 20 or the second linear transmission member 30 and the base member 40 are fixed, the fusing tool traces 26a, 36a that are recessed on the side opposite to the base member 40 of the first linear transmission member 20 or the second linear transmission member 30 (see FIG. 1), and the fusing tool traces (26b, 36b) that are recessed on the side opposite to the linear transmission members 20, 30 of the base member 40 include the portions that are the first fusion part 26 or the second fusion part 36.

[0073] Since the first fusion part 26 and the second fusion part 36 are configured as separate fusion parts, traces of separately forming the first fusion part 26 and the second fusion part 36 remain.

[0074] For example, in FIG. 2, as shown by a first fusion part 26 (and its fusion tool trace 26b) that fuses the one-end straight part 21La and the base member 40, and a second fusion part 36 (and its fusion tool trace 36b) that fuses the one-end straight part 31La and the base member 40, it is assumed that the first fusion part 26 and the second fusion part 36 are separated from each other.

[0075] For example, if the first fusion part 26 and the second fusion part 36 are formed in different regions at different timings, the first fusion part 26 and the second fusion part 36 are formed at separated positions. Also, if the first fusion part 26 and the second fusion part 36 are formed in different regions separated from each other by different fusion tools even at the same timing, the first fusion part 26 and the second fusion part 36 are formed at separated positions.

[0076] In particular, since a gap S between the one-end straight part 21La of the first linear transmission member 20 and the one-end straight part 31La of the second linear transmission member 30 is larger than the gaps of the plurality of first linear transmission members 20 and the gaps of the plurality of second linear transmission members 30, it is easy to form the first fusion part 26 and the second fusion part 36 separately. In the present embodiment, the gaps of the plurality of first linear transmission members 20 are 0, and the gaps of the plurality of second linear transmission members 30 are also 0. Note that there may be unavoidably generated gaps in the gaps of the plurality of first linear transmission members 20 and the gaps of the plurality of second linear transmission members 30 due to the bending habits of the linear transmission members 20 and 30 and the limits in the alignment process.

[0077] For example, in FIG. 2, as shown by a first fusion part 26 (and its fusion tool trace 26b) that fuses the middle straight part 21M and the base member 40, and a second fusion part 36 (and its fusion tool trace 36b) that fuses the middle straight part 31M and the base member 40, it is assumed that a boundary B exists between the first fusion part 26 and the second fusion part 36.

[0078] Boundary B may be the trace of the outer edge of the portion of the welding tool that contacts the base member 40, for example, the trace of the edge of the contact surface of the horn or anvil for ultrasonic welding. Even when the welding tool traces 26b of the first welding portion 26 and the welding tool trace 36b of the second welding portion 36 are adjacent to each other, it is conceivable that their boundary B remains as the edge trace of the welding tool. For example, even when a group of a plurality of intermediate straight portions 21M and a group of a plurality of intermediate straight portions 31M are adjacent to each other and in contact, and the welding tool for welding both is pressed against the base member 40 in the region where they are adjacent to each other, it is conceivable that the trace of the welding tool remains at their boundary B.

[0079] <Example of manufacturing method of wiring member> An example of the manufacturing method of the above wiring member 10 will be described.

[0080] As shown in FIG. 3, a plurality of first linear transmission members 20 are arranged on the base member 40. The entire plurality of first linear transmission members 20 may be arranged on the base member 40 at the same time, or the plurality of first linear transmission members 20 may be arranged on the base member 40 while being sequentially welded from one end side along the longitudinal direction.

[0081] The plurality of first linear transmission members 20 are aligned in a parallel state, and the plurality of first linear transmission members 20 are collectively welded to the base member 40. The welding is performed, for example, as shown in FIG. 4, by sandwiching the plurality of first linear transmission members 20 arranged in a parallel state on the base member 40 with a pair of welding tools 50 and 52 and applying energy for welding. Thereby, the plurality of first linear transmission members 20 are simultaneously welded and fixed to the base member 40 in a parallel state, and the first welding portion 26 is formed. The plurality of first welding portions 26 are formed at intervals in the longitudinal direction of the plurality of first linear transmission members 20. The plurality of first welding portions 26 may be formed sequentially or simultaneously in the longitudinal direction of the plurality of first linear transmission members 20.

[0082] Next, a plurality of second linear transmission members 30 are arranged on the base member 40. The entire plurality of second linear transmission members 30 may be arranged on the base member 40 simultaneously, or the plurality of second linear transmission members 30 may be arranged on the base member 40 while being sequentially fused from one end side along the longitudinal direction.

[0083] The plurality of second linear transmission members 30 are aligned in a parallel state, and the plurality of second linear transmission members 30 are collectively fused to the base member 40. The fusing is performed, for example, as shown in FIG. 5, by sandwiching the plurality of second linear transmission members 30 arranged in a parallel state on the base member 40 with a pair of fusing tools 54 and 56 and applying energy for fusing. Thereby, the plurality of second linear transmission members 30 are fused and fixed to the base member 40 simultaneously in a parallel state, and a second fused portion 36 is formed. The plurality of second fused portions 36 are formed at intervals in the longitudinal direction of the plurality of second linear transmission members 30. The plurality of second fused portions 36 may be sequentially formed or simultaneously formed in the longitudinal direction of the plurality of second linear transmission members 30.

[0084] When the number, material, or thickness of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are different, there is a possibility that the widths or the shapes of the contact surfaces are different between the fusing tools 50, 52 and the fusing tools 54, 56. Also, there is a possibility that the fusing conditions for forming the first fused portion 26 and the second fused portion 36, such as the fusing time, the target temperature, or the pressurizing conditions, are different.

[0085] By separating the first fused portion 26 and the second fused portion 36, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 can be fused under conditions suitable for each. Also, by dividing the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 into smaller portions, it becomes easier to arrange them in a parallel state.

[0086] In the above example, the operation of fusing a plurality of first linear transmission members 20 and the operation of fusing a plurality of second linear transmission members 30 are described as separate operations in which the fusing tools 50 and 52 are different from the fusing tools 54 and 56, and the fusing timing is different. Both operations may be performed using the same fusing tool.

[0087] Also, as shown in FIG. 6, the operation of fusing a plurality of first linear transmission members 20 and the operation of fusing a plurality of second linear transmission members 30 may be performed at the same timing, with the fusing tools 50 and 52 being different from the fusing tools 54 and 56.

[0088] In this case, the fusing tools 50 and 52 and the fusing tools 54 and 56 may be arranged adjacent to each other. Even in that case, it is assumed that a gap is formed between the first fused portion 26 and the second fused portion 36 due to a fine gap or step between the fusing tools 50 and 52 and the fusing tools 54 and 56.

[0089] Also, as shown in FIG. 7, when fusing the one - end - side straight portion 21La and the one - end - side straight portion 31La, whether both operations are performed at the same timing or at different timings, the fusing tools 50 and 52 and the fusing tools 54 and 56 are arranged apart from each other, and thus, it is conceivable that the first fused portion 26 and the second fused portion 36 are separated.

[0090] In the above embodiment, in the above example, an example is described in which the first fused portion 26 for fusing a plurality of second linear transmission members 30 and the second fused portion 36 for fusing a plurality of second linear transmission members 30 are at the same position in the extending direction of those linear transmission members 20 and 30. However, like the wiring member 110 shown in FIG. 8, the first fused portion 126 corresponding to the first fused portion 26 and the second fused portion 136 corresponding to the second fused portion 136 may be arranged offset in the extending direction of the linear transmission members 20 and 30.

[0091] <Effects, etc.> According to the wiring member 10 configured as described above and its manufacturing method, a plurality of first linear transmission members 20 and a plurality of second linear transmission members 30 grouped according to connection destinations are fused and fixed to the base member 40 via separate first fusion portions 26 or second fusion portions 36.

[0092] Therefore, when there is a reduction, addition, or wire type change in the plurality of first linear transmission members 20 or the plurality of second linear transmission members 30, it can be dealt with by changing the process related to the first fusion portion 26 or the second fusion portion 36.

[0093] For example, as shown in FIG. 9, assume that a linear transmission member 20x is added to the plurality of first linear transmission members 20 planned at the initial stage. In this case, without changing the fusing tool and fusing conditions for forming the second fusion portion 36, the fusing tool or fusing conditions for forming the first fusion portion 26 may be changed. Therefore, only the manufacturing apparatus, conditions, etc. need to be partially changed, and it is easy to respond to design changes.

[0094] Also, even if rework is required for the plurality of first linear transmission members 20 or the plurality of second linear transmission members 30, it can be dealt with by reworking the plurality of first linear transmission members 20 or the plurality of second linear transmission members 30.

[0095] For example, as shown in FIG. 10, assume that a part of the traces of the plurality of first fusion portions 26 that fuse the plurality of first linear transmission members 20 to the base member 40 are formed at a position 26F shifted from the first linear transmission members 20. In this case, without affecting the plurality of second linear transmission members 30, the work of fusing the plurality of first linear transmission members 20 can be redone. Thus, by separately fusing the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, one defect can be separately repaired, and the repair work becomes easier compared to the case of repairing the whole. Therefore, it is easy to respond to design changes or repairs of the wiring member 10.

[0096] Also, since the first fusion portion 26 and the second fusion portion 36 are separated, it is easy to fuse the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 without affecting each other.

[0097] Also, since a boundary B exists between the first fusion part 26 and the second fusion part 36, it is easy to perform fusion with different conditions for the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 separately by the fusion tools 50, 52 or the fusion tools 54, 56, or by changing the timing.

[0098] Also, since 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 gaps between the plurality of linear transmission members and the gaps between the plurality of linear transmission members, it is easy to separately fuse the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30.

[0099] Also, in the terminal regions of the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30, the gap S between the one - end - side straight portion 21La (or the other - end - side straight portion 21Lb) of the plurality of first linear transmission members 20 and the one - end - side straight portion 31La (or the other - end - side straight portion 31Lb) of the plurality of second linear transmission members 30 is larger than the gap between the one - end - side straight portion 21La (or the other - end - side straight portion 21Lb) of the plurality of linear transmission members 20 and the gap between the one - end - side straight portion 31La (or the other - end - side straight portion 31Lb) of the plurality of linear transmission members 30. Therefore, it is easy to set 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 according to the destinations of the terminals of the linear transmission members 20, 30.

[0100] Also, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 are arranged on the base member 40 so as to avoid intersection. Therefore, each can be independently designed or repaired, and it is easy to respond to the design change or repair of the wiring member 10.

[0101] In addition, one end of each of the plurality of first linear transmission members 20 is connected to a common one - end - 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 - end - side first connector 29. As a result, the plurality of first linear transmission members 20 are configured as a first wiring module component 20M. Also, one end of each of the plurality of second linear transmission members 30 is connected to a common one - end - 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 - end - side second connector 39. Thus, the plurality of second linear transmission members 30 are configured as a second wiring module component 30M, which is a component different from the first wiring module component 20M. Therefore, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 can be separately designed and modified, and are also easy to repair.

[0102] Further, the plurality of first linear transmission members 20 are integrally fused to the base member 40 in a parallel state, and the plurality of second linear transmission members 30 are integrally fused to the base member 40 in a parallel state. In this case, both fusing operations are carried out as separate operations with different fusing timings or different fusing tools 50, 52, fusing tools 54, 56. Therefore, the plurality of first linear transmission members 20 and the plurality of second linear transmission members 30 can be separately designed and modified or easily repaired.

[0103] Note that the respective configurations described in the above - mentioned embodiments and each modification can be appropriately combined as long as they do not conflict with each other.
