[0026] [Details of Embodiments of the Present Disclosure]

[0027] Hereinafter, specific examples of the wiring member of the present disclosure will be described with reference to the accompanying drawings. Figure 1 Note that the present disclosure is not limited to these examples, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0028] [Embodiment]

[0029] Hereinafter, the wiring member of the embodiment will be described. Figure 1 is a plan view showing the wiring member 10. Figure 2 is a cross-sectional view taken along the line II-II in Figure 1

[0030] The wiring member 10 is provided with a base member 20 and a linear transmission member 30.

[0031] The base member 20 has a holding surface 22. The linear transmission member 30 is disposed on the holding surface 22. On the holding surface 22, the linear transmission member 30 is held so as to trace a prescribed path. That is, the base member 20 is a member having the holding surface 22 that holds the linear transmission member 30 along the prescribed path. The base member 20 can be a member having the holding surface 22 for holding the linear transmission member 30. The base member 20 can be formed in a sheet shape, or can be formed in a three-dimensional shape. The holding surface 22 can be a flat surface, or can be a curved surface, or can be a concave-convex surface, or can be a composite surface of a flat surface and another curved surface, or the like.

[0032] Here, the base member 20 is described as a member having a flat flat portion (more specifically, a sheet member 20 that can be bent).

[0033] The sheet member 20 can be formed in a shape along the wiring path of the linear transmission member 30. Here, the sheet member 20 is formed in a rectangular shape that is long in one direction. The sheet member can also be bent. The sheet member can also have a portion bent in a curved shape. The sheet member can also have a branched portion.

[0034] ​The material constituting the sheet member 20 is not particularly limited, but the sheet member 20 can be formed of a material containing a resin such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), PP (polypropylene), or the like. The sheet member 20 can be a sheet material that is uniformly filled inside, or a nonwoven sheet, or the like. The sheet member 20 sometimes contains a material such as metal. The sheet member 20 preferably has flexibility that is easily bent in the thickness direction. The sheet member 20 can be a single layer, or can be a plurality of layers stacked. In the case of a plurality of layers stacked, for example, it is conceivable that a resin layer and a resin layer are stacked in the sheet member 20. More specifically, for example, it is conceivable that a nonwoven sheet and a resin sheet material that is uniformly filled inside are stacked in the sheet member 20. In addition, for example, it is conceivable that a resin layer and a metal layer are stacked in the sheet member 20.

[0035] The wire-like transmission member 30 is assumed to be a wire-like transmission member that connects components in a vehicle in a manner that enables communication or enables power supply. The wire-like transmission member 30 is provided on the holding surface 22 side in a manner that extends along a wiring path corresponding to the position of a component that is a connection destination or the like.

[0036] More specifically, the wire-like transmission member 30 is a wire-like member that transmits electricity or light, or the like. For example, the wire-like transmission member 30 can be a general electric wire having a core wire 32 and a covering 34 around the core wire 32, or can be a bare conductor, a shielded wire, a stranded wire, an enameled wire, a nichrome wire, an optical fiber, or the like.

[0037] As the wire-like transmission member 30 that transmits electricity, various signal wires, various power lines, or the like can be used. A part of the wire-like transmission member that transmits electricity or the like can also be used as an antenna, a coil, or the like that transmits or receives a signal or electricity to or from space.

[0038] In addition, the wire-like transmission member 30 can be a single wire, or can be a composite of a plurality of wires (a stranded wire, a cable in which a plurality of wires are gathered and covered with a sheath, or the like).

[0039] The wire-like transmission member 30 is held on the holding surface 22 of the sheet member 20. The specific structure for holding is not particularly limited as long as the wire-like transmission member 30 is held in a manner that is provided along a certain path with respect to the sheet member 20.

[0040] For example, the linear transmission member 30 can be fused (also referred to as welded) with respect to the holding surface 22 of the sheet member 20. The fusion portion thus formed becomes a state in which at least one of the linear transmission member 30 and the sheet member 20 is melted / dissolved and adheres to each other. The fusion of the linear transmission member 30 and the sheet member 20 can be performed by ultrasonic fusion, or can be performed by heat fusion. Alternatively, the linear transmission member 30 and the sheet member 20 can be fused by dissolving at least one of the surfaces of the linear transmission member 30 and the sheet member 20 with a solvent. Alternatively, for example, the linear transmission member 30 can be fixed with respect to the sheet member 20 by an adhesive, a double-sided tape, or the like. Alternatively, for example, the linear transmission member 30 can be sewn with respect to the sheet member 20 by a thread or the like. Alternatively, for example, the linear transmission member 30 can be adhered to the holding surface 22 of the sheet member 20 in a state in which the linear transmission member 30 is disposed on the holding surface 22 of the sheet member 20 in a manner so as to cross the linear transmission member 30, and an adhesive tape can be adhered to the holding surface 22 of the sheet member 20 in a manner so as to cross the linear transmission member 30, whereby the linear transmission member 30 is held to the holding surface 22 of the sheet member 20.

[0041] Here, an example in which the linear transmission member 30 is an electric wire 30 having a core wire 32 and a covering 34 is described. Further, an example in which the electric wire 30 is fused to the holding surface 22 of the sheet member 20 via a fusion portion 38 is described. Further, in each drawing, the electric wire 30 can be held in a straight line on the holding surface 22, or can be held in a bent manner. In a case in which a plurality of electric wires 30 are present, a portion of the plurality of electric wires 30 can branch from another electric wire. Further, an end portion of the electric wire 30 extends from an end portion of the sheet member 20. The end portion of the electric wire 30 is connected to the connector 14.

[0042] The missing linear transmission member identification mark 28 indicating the position of the missing linear transmission member is provided on the holding surface 22. The missing linear transmission member identification mark 28 can be any mark as long as it is a mark that can be visually recognized. For example, the missing linear transmission member identification mark 28 can be provided by a concave-convex shape formed on the surface of the sheet member 20. Alternatively, for example, the missing linear transmission member identification mark 28 can be formed by a paint attached to the surface of the sheet member 20. In the present embodiment, an example in which the missing linear transmission member identification mark 28 is provided by a concave-convex shape formed on the surface of the sheet member 20 is described. In the present embodiment, the missing linear transmission member identification mark 28 is provided on the holding surface 22 of the sheet member 20. However, the missing linear transmission member identification mark 28 can be provided on the holding surface 22 of the sheet member 20, or can be provided on the holding surface 22 of the sheet member 20 and the holding surface 22 of the sheet member 20. Figure 1 and Figure 2 In the present embodiment, the missing linear transmission member identification mark 28 is formed by forming two short concave-convex portions at an interval corresponding to the diameter of the electric wire 30 with respect to the holding surface 22. Note that, regarding the reference numeral 28 of the missing linear transmission member identification mark 28, in the following description, a number is sometimes added in parentheses after the reference numeral 28 in order to distinguish between them.

[0043] The missing linear transmission member position will be described. First, the missing linear transmission member is a linear transmission member that is sometimes held on the holding surface depending on the kind of the wiring member but is not actually held. The missing linear transmission member position is a position at which a linear transmission member corresponding to such a missing linear transmission member can be held.

[0044] A more specific example will be described with reference to Figure 3 The wiring member 110 incorporated in the vehicle to a certain portion will be assumed. The wiring member 110 electrically connects, for example, two portions in the vehicle. The wiring member 110 sometimes has electric wires 30 incorporated or not incorporated depending on the level, optional components in the vehicle, in addition to the electric wires 30 common to the levels, optional components. For ease of description, the wiring member 110 including the most electric wires 30 will be assumed. The six electric wires 30 in the wiring member 110 are sometimes classified into electric wires 30(1), 30(2), 30(3), 30(4), 30(5), 30(6) as needed.

[0045] In addition, wiring members 110B, 110C, 110D in which any electric wire 30 is omitted with respect to the above-described wiring member 110 are set. The electric wires 30(1), 30(2), 30(3), 30(4), 30(5) are held on the holding surface 22 of the wiring member 110B, and the electric wire 30(6) is omitted. That is, the electric wire 30(6) is a missing linear transmission member. The electric wires 30(1), 30(4), 30(5) are held on the holding surface 22 of the wiring member 110C, and the electric wires 30(2), 30(3), 30(6) are omitted. That is, the electric wires 30(2), 30(3), 30(6) are missing linear transmission members. The electric wires 30(1), 30(2), 30(5) are held on the holding surface 22 of the wiring member 110D, and the electric wires 30(3), 30(4), 30(6) are omitted. That is, the electric wires 30(3), 30(4), 30(6) are missing linear transmission members.

[0046] As understood from Figure 3 In a case where any one of the wiring members 110B, 110C, 110D is observed alone, it is difficult to know which electric wire 30 is omitted, and thus it is difficult to identify the kind of the wiring member 110B, 110C, 110D. For example, in a case where the wiring member 110B is observed, it is difficult to know by itself whether there is an omitted electric wire (missing linear transmission member). Also in a case where the wiring members 110C, 110D are observed, it is difficult to know whether the gap between the electric wires 30 is a gap originally present or a gap present as a result of the presence of an omitted electric wire (missing linear transmission member).

[0047] In contrast, as Figure 1or Figure 4 As shown, when a missing linear transmission component identification mark 28 is marked at the location of the missing linear transmission component, it is easy to identify where the wire 30 is omitted. Figure 4 In this process, the components obtained by marking the missing linear transmission component identification mark 28 on the wiring component 110B are classified as wiring component 10B, the components obtained by marking the missing linear transmission component identification mark 28 on the wiring component 110C are classified as wiring component 10C, and the components obtained by marking the missing linear transmission component identification mark 28 on the wiring component 110D are classified as wiring component 10D.

[0048] For example, in wiring component 10B, the location of the omitted wire 30 (6) is marked with a missing linear transmission component identification mark 28 (6). Additionally, in wiring component 10C, the locations of the omitted wires 30 (2), 30 (3), and 30 (6) are marked with missing linear transmission component identification marks 28 (2), 28 (3), and 28 (6). Furthermore, in wiring component 10D, the locations of the omitted wires 30 (3), 30 (4), and 30 (6) are marked with missing linear transmission component identification marks 28 (3), 28 (4), and 28 (6). Figure 1 and Figure 2 The wiring component 10 shown corresponds to Figure 4 The wiring component 10D is used. Therefore, by observing the wiring components 10B, 10C, and 10D, it is easy to identify which of the wires 30(1), 30(2), 30(3), 30(4), 30(5), and 30(6) is retained or omitted. Thus, it is easy to identify the types of wiring components 110, 10B, 10C, and 10D.

[0049] It should be noted that, in Figure 4 In the wiring components 10C and 10D shown, multiple missing linear transmission component identification marks 28 are provided to indicate the locations of multiple missing linear transmission components. For example, in wiring component 10C, each of the multiple missing linear transmission component identification marks 28(2), 28(3), and 28(6) indicates the location of a corresponding missing linear transmission component. Alternatively, as in wiring component 10B, only one missing linear transmission component identification mark 28(6) indicating the location of one missing linear transmission component may be provided.

[0050] As with the wiring members 10C, 10D, in a structure in which at least a part of the plurality of electric wires 30 is held in a side-by-side state to the holding surface 22, the missing linear transmission member identification mark 28 can include an intermediate identification mark provided between the plurality of electric wires 30 at the side-by-side holding portion. In the wiring member 10C, the missing linear transmission member identification marks 28(2), 28(3) are intermediate identification marks. In the wiring member 10D, the missing linear transmission member identification marks 28(3), 28(4) are intermediate identification marks.

[0051] In addition, as with the wiring members 10B, 10C, 10D, in a structure in which at least a part of the plurality of electric wires 30 is held in a side-by-side state to the holding surface 22, the missing linear transmission member identification mark 28 can also include an outside identification mark provided at a position outside in the side-by-side direction. In the wiring members 10B, 10C, 10D, the missing linear transmission member identification mark 28(6) is an outside identification mark.

[0052] Each of the above-described missing linear transmission member identification marks 28 is formed along the path of the corresponding electric wire 30. Thus, the missing linear transmission member identification mark 28 includes a plurality of marks 28a provided per 1 of the corresponding missing linear transmission members (electric wires) 30 and indicates the path of the corresponding missing linear transmission members (electric wires) 30. The missing linear transmission member identification mark 28 is not necessarily required to indicate the path of the corresponding missing linear transmission members (electric wires) 30. For example, as with the wiring member 210 shown in FIG. 21, the missing linear transmission member identification mark 228 can indicate only 1 position on the path of the corresponding missing linear transmission member (electric wire). Figure 5

[0053] The missing linear transmission member identification mark 28 can also be provided next to the fusion portion 38. In the present embodiment, each electric wire 30 is fused by a plurality of fusion portions 38. In the extension direction of the electric wire 30, the plurality of fusion portions 38 are provided at a prescribed interval. The interval of the plurality of fusion portions 38 can be constant or can be changed. In other words, the electric wire 30 is intermittently fused to the holding surface 22 by the plurality of fusion portions 38.

[0054] The missing linear transmission member identification mark 28 also includes a plurality of marks 28a provided intermittently along the path of the corresponding electric wire 30. The plurality of marks 28a are formed at the same interval as the plurality of fusion portions 38. Thus, the plurality of marks 28a are formed next to the plurality of fusion portions 38. For example, when the electric wire 30 is fused to the holding surface 22 to form the fusion portion 38, the plurality of marks 28a of the missing linear transmission member identification mark 28 can be easily formed using the device for the fusion, heat energy, and the like.

[0055] ​According to the wiring member 10B, 10C, 10D thus configured, in which the missing linear transmission member identification mark 28 in the holding surface 22 is a clue, it is easy to identify whether or not any of the electric wires 30 is missing with respect to the wiring member 110. Thus, the kind of the wiring member 110, 10B, 10C, 10D is easily identified.

[0056] Further, the wiring member 10B, 10C, 10D is provided with a plurality of missing linear transmission member identification marks 28. Thus, a plurality of kinds of wiring members 10B, 10C, 10D in which a plurality of the electric wires 30(1), 30(2), 30(3), 30(4), 30(5), 30(6) are missing can be easily identified.

[0057] Further, the missing linear transmission member identification mark 28 indicates the path of the electric wire 30. Thus, it is possible to identify the path of the missing electric wire 30, its connection destination, and the like. Thus, the identification of the wiring member 10B, 10C, 10D is further easily performed.

[0058] Further, in a case where the missing linear transmission member identification mark 28 includes the missing linear transmission member identification marks 28(2), 28(3), 28(4) as the intermediate identification marks provided between the electric wires 30 at the parallel portion of the plurality of electric wires 30, it is easy to identify whether the gap of the plurality of electric wires 30 is a simple gap or a gap generated as a result of the missing electric wire 30. Thus, the identification of the wiring member 10B, 10C, 10D is further easily performed. Further, in a case where the missing linear transmission member identification mark 28 includes the missing linear transmission member identification mark 28(6) as the outside identification mark provided outside the parallel direction of the electric wires 30 at the parallel portion of the plurality of electric wires 30, it is easy to identify whether the gap of the outside of the plurality of electric wires 30 is a simple gap or a gap generated as a result of the missing electric wire 30. Thus, the identification of the wiring member 10B, 10C, 10D is further easily performed.

[0059] Further, in a case where the missing linear transmission member identification mark 28 is provided beside the fusion portion 38, it is easy to form each mark 28a of the missing linear transmission member identification mark 28 at the time of fusion of the electric wire 30 to the holding surface 22.

[0060] Note that each structure described in the above embodiment and each modification example can be appropriately combined as long as they do not contradict each other.
