[0018] [Description of embodiments of this disclosure]

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

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

[0021] (1) A wiring component having a wiring body and a pattern, wherein the wiring body includes a plurality of linear transmission components and a substrate, the plurality of linear transmission components being fixed to the substrate in a side-by-side manner, and the pattern being disposed on the wiring body such that at least a portion of the portion of the wiring body related to the substrate can be identified in two dimensions.

[0022] The pattern set on the wiring harness makes it easy to identify the predetermined positions in the wiring components.

[0023] Here, a linear transmission component refers to a linear component that transmits electricity or light, etc.

[0024] (2) It is conceivable that the above-mentioned pattern includes an outer edge identification pattern, wherein the outer edge identification pattern is formed in such a way that the color of the outer edge of the substrate is different from the color of the middle part of the substrate. In this case, a contrast is easily generated between the outer edge and the middle part of the substrate, making it easy to identify the outer edge of the substrate.

[0025] (3) It is conceivable that the above pattern includes a feature portion, which presents an appearance inconsistent with other parts in the above wiring harness. In this case, the part with the feature portion can be easily identified by recognizing the feature portion.

[0026] (4) It is conceivable that the aforementioned feature portion includes a shape-specific portion, which is a portion in the shape of the substrate whose shape is different from the shape of other portions. In this case, the feature portion can be formed by the shape of the substrate.

[0027] (5) It is conceivable that the aforementioned feature portion includes a path-specific portion, which is a portion in which the appearance of a part of the path of the linear transmission member in the substrate is formed differently from the appearance of the path of other parts. In this case, the feature portion can be formed by the appearance of the path of the linear transmission member.

[0028] (6) It is conceivable that the aforementioned feature includes a mark, which is applied to a portion of the surface of the aforementioned substrate. In this case, the feature can be formed by the mark on the substrate.

[0029] (7) It is conceivable that the aforementioned substrate comprises a sheet and a cover, the aforementioned linear transmission component is fixed to the aforementioned sheet, and the aforementioned cover is formed to have a higher rigidity than the aforementioned sheet and is fixed to the aforementioned sheet, covering the aforementioned linear transmission component. In this case, since the rigidity of the wiring component is increased by the cover, the wiring component is easier to maintain a constant shape. Therefore, by using a pattern to identify the position of a portion in the substrate, any position in the substrate can be easily determined.

[0030] [Details of the embodiments disclosed herein]

[0031] Specific examples of wiring components of this disclosure will now be described with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples, but is shown in the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0032] [Implementation Method 1]

[0033] The wiring components involved in Embodiment 1 will be described below. Figure 1 This is a top view showing the wiring component 10 according to Embodiment 1. Figure 2 It is along Figure 1 A cross-sectional view cut off along line II-II. Additionally, in Figure 1 , Figure 2 In order to make the differences in color based on pattern 40 easier to understand in the substrate 30, a sandy shading line is applied to a portion of it.

[0034] The wiring component 10 includes a wiring body 20 and a pattern 40 disposed on the wiring body 20.

[0035] The wiring harness 12 is a component mounted on a vehicle to supply power to various devices in the vehicle and to transmit and receive signals. The wiring harness 12 includes multiple linear transmission components 20 and a substrate 30. The wiring harness 12 is formed in a flat shape.

[0036] The linear transmission component 20 can be any linear component that transmits electricity or light. For example, the linear transmission component 20 can be a regular wire with a core wire and a sheath around the core wire, or it can be a shielded wire, twisted pair wire, enameled wire, nickel-chromium alloy wire, bare wire, optical fiber, etc.

[0037] The linear transmission component 20 for transmitting electricity can be various signal lines or various power lines. The linear transmission component 20 for transmitting electricity can be used as an antenna, coil, etc., to transmit signals or electricity into or from space.

[0038] exist Figure 2 In the example shown, the linear transmission component 20 includes a transmission line body 22 for transmitting electricity or light, and a sheathing layer 24 covering the transmission line body 22. When the linear transmission component 20 is a regular electrical wire, the transmission line body 22 is the core wire, and the sheathing layer 24 is an insulating sheathing layer. Furthermore, in... Figure 2 In the example shown, multiple linear transmission components 20 with the same diameter and structure are arranged on a substrate 30. However, the diameter and structure of the multiple linear transmission components 20 can be set appropriately, and linear transmission components 20 with different diameters and structures can also be arranged on the same substrate 30.

[0039] Furthermore, the linear transmission component 20 can be a single linear object or a composite of multiple linear objects (such as stranded wire, a cable that combines multiple linear objects and covers them with a sheath). At the end of the linear transmission component 20, terminals, connectors C, etc., are appropriately provided depending on the connection method between the linear transmission component 20 and the mating component.

[0040] Multiple linear transmission components 20 are fixed to the substrate 30 in a parallel arrangement. The substrate 30 holds the multiple linear transmission components 20 in a flat manner. The substrate 30 is a component that holds the linear transmission components 20 in a two-dimensional positioning state. The substrate 30 includes a sheet 32 ​​and a cover 34.

[0041] A linear transmission member 20 is disposed on one main surface of the sheet 32. The sheet 32 ​​holds the multiple linear transmission members 20 in a side-by-side arrangement. The sheet 32 ​​may be a member with the rigidity to the extent that it can be bent and hold the multiple linear transmission members 20 in a planar positioning state, or it may be a member with the rigidity to the extent that it can hold the multiple linear transmission members 20 in a two-dimensional positioning state while maintaining a flat state. The sheet 32 ​​may also have a three-dimensional shape such as a partially erected wall. Here, the case where the sheet 32 ​​is a bendable member will be described.

[0042] The material constituting the sheet 32 ​​is not particularly limited. The sheet 32 ​​may be formed from materials containing resins such as PVC (polyvinyl chloride), PET (polyethylene terephthalate), and PP (polypropylene). The sheet 32 ​​can be a fibrous material containing fibers, such as non-woven fabric, woven fabric, or knitted fabric, or it can be a non-fibrous material. As a non-fibrous material, it can be a solid sheet uniformly filled internally or a foam formed by resin foaming. The sheet 32 ​​may also contain materials such as metal.

[0043] Sheet 32 ​​can be a single layer or multiple layers stacked together. In the case of multiple layers stacked together, for example, it can be a resin layer stacked with resin layers. Alternatively, for example, it can be a resin layer and a metal layer stacked together. Furthermore, sheet 32 ​​can be a component formed by overlapping non-fibrous material layers, overlapping non-fibrous material layers with fibrous material layers, or overlapping fibrous material layers with fibrous material layers.

[0044] The linear transmission member 20 is fixed to the sheet 32 ​​on its main surface in a manner arranged along a predetermined path. The sheet 32 ​​is formed as a strip extending along the path of the linear transmission member 20. The path of the linear transmission member 20 on the sheet 32 ​​can be appropriately set; the linear transmission member 20 can be arranged in a straight line or in a curved manner on the sheet 32. When the linear transmission member 20 is arranged in a curved manner on the sheet 32, the sheet 32 ​​can also be formed in a curved manner. Multiple linear transmission members 20 can also be arranged along different paths in a manner that branches or crosses on the sheet 32. In this case, the sheet 32 ​​can also be formed in a branching or crossing manner.

[0045] exist Figure 1 In the example shown, multiple linear transmission components 20 are bent midway and arranged in an L-shape. The sheet 32 ​​is formed in an L-shape along the path of the multiple linear transmission components 20. By forming the sheet 32 ​​in a shape that follows the path of the multiple linear transmission components 20, interference between the sheet 32 ​​and other components can be suppressed, and weight reduction can be achieved. Of course, the sheet 32 ​​does not necessarily have to be formed in a shape that follows the path of the multiple linear transmission components 20; it can also be formed in other shapes such as a square.

[0046] The linear transmission component 20 and the sheet 32 ​​are fixed together. The fixing method can be contact fixing, non-contact fixing, or a combination of both. Contact fixing refers to fixing the linear transmission component 20 and the sheet 32 ​​by bonding the parts that contact each other. Non-contact fixing refers to a fixing method where the linear transmission component 20 is not fixed at the contact points. For example, the linear transmission component 20 is pressed against the sheet 32 ​​by sewing thread, other sheets, tape, etc., or the linear transmission component 20 and the sheet 32 ​​are sandwiched together by sewing thread, other sheets, tape, etc., thereby maintaining the linear transmission component 20 and the sheet 32 ​​in a fixed state. The following explanation describes the case where the linear transmission component 20 and the sheet 32 ​​are fixed at the contact points. The explanations regarding contact fixing can also be applied to non-contact fixing, provided the structure is not unapplicable.

[0047] The method of fixing this contact point can be indirect or direct, or both can be used in different areas. Indirect fixing refers to the indirect bonding and fixing of the linear transmission member 20 and the sheet 32 ​​through an intervening component such as an adhesive, glue, double-sided tape, or hook and loop fastener. Direct fixing refers to the direct bonding and fixing of the linear transmission member 20 and the sheet 32 ​​without the use of a separate adhesive. In direct fixing, for example, it is conceivable to bond by melting the resin contained in at least one of the linear transmission member 20 and the sheet 32. The following describes the case where the linear transmission member 20 and the sheet 32 ​​are in a directly fixed state. The descriptions of direct fixing can also be applied to indirect fixing, provided that the structure is not unapplicable.

[0048] When this directly fixed state is formed, one can imagine either the resin melting by heat or dissolving by a solvent. That is, the directly fixed state can be either heat-based or solvent-based. Preferably, the heat-based directly fixed state is preferable.

[0049] At this time, the method for forming a directly fixed state is not particularly limited, and various methods, including known methods such as fusion, welding, and fusion bonding, can be used. For example, when forming a heat-based directly fixed state through fusion, various fusion methods such as ultrasonic fusion, heat-pressure fusion, hot air fusion, and high-frequency fusion can be used. Furthermore, when a directly fixed state is formed through these methods, the linear transmission component 20 and the sheet 32 ​​become directly fixed based on that method. Specifically, for example, when a directly fixed state is formed through ultrasonic fusion, the linear transmission component 20 and the sheet 32 ​​become directly fixed based on ultrasonic fusion. The portion that forms a heat-based directly fixed state through fusion (the fixed portion of the linear transmission component 20 and the sheet 32) can also be called the fusion section, the fixed portion based on ultrasonic fusion can be called the ultrasonic fusion section, and the fixed portion based on heat-pressure fusion can be called the heat-pressure fusion section, etc.

[0050] In the case of direct fixation, only the resin contained in the coating layer 24 of the linear transport member 20 or only the resin contained in the sheet 32 ​​can be melted. In these cases, the molten resin adheres to the outer surface of the other, forming a relatively distinct interface. Alternatively, in the case of direct fixation, both the resin contained in the coating layer 24 of the linear transport member 20 and the resin contained in the sheet 32 ​​can be melted. In this case, the two resins may sometimes mix together without forming a distinct interface. In particular, when the coating layer 24 of the linear transport member 20 and the sheet 32 ​​contain easily compatible resins such as the same resin material, the two resins may sometimes mix together without forming a distinct interface.

[0051] Cover 34 is fixed to sheet 32. Cover 34 covers the linear transmission member 20 from the side opposite to sheet 32. Cover 34 is not fixed to the linear transmission member 20, but it can be fixed.

[0052] The sheet 32 ​​and the cover 34 are fixed at the portions extending laterally toward the linear conveying member 20. As a method of fixing the sheet 32 ​​and the cover 34, in Figure 2 The example shown illustrates direct fixation without the use of adhesives or other intervening agents. Of course, the fixation method between sheet 32 ​​and cover 34 is not limited to direct fixation; various fixation methods described in the fixation method between sheet 32 ​​and linear transmission member 20 can be used.

[0053] Sheet 32 ​​and cover 34 may use the same sheet component or different sheet components. Here, sheet 32 ​​and cover 34 use different sheet components. Here, the sheet component for sheet 32 ​​is more suitable for fixing to the linear transport member 20 than the sheet component for cover 34. The sheet component for cover 34 has higher rigidity and better shape retention than the sheet component for sheet 32. For example, sheet 32 ​​is a component having a first layer and a second layer. The first layer is formed into a solid sheet shape from the same material as the covering layer 24 of the linear transport member 20 for fixing the linear transport member 20. The second layer is formed of nonwoven fabric and overlaps with the first layer. Cover 34 is a component formed into a solid sheet shape from nylon or the like.

[0054] The cover 34 is formed in the same shape as the sheet 32, covering the entire sheet 32. Therefore, the substrate 30 is formed in an L-shape with two orthogonal strip portions 36a and 36b. Of course, the cover 34 can also be formed in a different shape than the sheet 32, or it can cover a portion of the sheet 32.

[0055] Pattern 40 enables the identification of the two-dimensional position of at least a portion of the wiring harness 12 related to the substrate 30. The two-dimensional position referred to here is the two-dimensional position in a top view of the wiring harness 12 (substrate 30), that is, the two-dimensional position when viewed from a direction orthogonal to the thickness direction. Therefore, pattern 40 enables the identification of the two-dimensional position of at least a portion of the wiring harness 12 related to the substrate 30 in a top view. Furthermore, the portion related to the substrate 30 does not necessarily have to be the substrate 30; for example, it could be a portion of the linear transmission member 20 fixed to the substrate 30. Here, pattern 40 is configured to be identifiable in a top view from the cover 34 side. Of course, pattern 40 could also be configured to be identifiable in a top view from the sheet 32 ​​side. Pattern 40 is provided on the portion related to the substrate 30. In this example, pattern 40 is formed as an outer edge identification pattern.

[0056] The outer edge identification pattern 40 is the portion of the outer edge of the substrate 30 whose color differs from the color of the middle portion of the substrate 30. Figure 2 In the example shown, the outer edge identification pattern 40 is provided by marking the surface of the substrate 30 with a color different from that of the substrate 30. The material of the marking is not particularly limited. For example, the substrate 30 can be coated with paint, or a thin strip-shaped part narrower than the substrate 30 can be attached as the marking.

[0057] Of course, the outer edge identification pattern 40 is not limited to a mark. For example, if the surface of the cover 34 and the surface of the sheet 32 ​​are different colors, the protrusion formed by the outer edge of one of the sheet 32 ​​and the cover 34 extending from the outer edge of the other can also be used as the outer edge identification pattern 40.

[0058] The width of the outer edge identification pattern 40 is not particularly limited, as long as it is a recognizable size. For example, when using image processing to identify the outer edge identification pattern 40, the width of the outer edge identification pattern 40 can be set according to the resolution of the imaging unit. Specifically, in the captured image obtained by imaging the entire substrate 30, the number of pixels in the width direction of the outer edge identification pattern 40 can be a few pixels.

[0059] Preferably, the substrate 30 is not rotationally symmetrical in the top view. That is, it is preferable that the substrate 30 is formed in a non-rotationally symmetrical shape in the top view. If the substrate 30 is formed in a non-rotationally symmetrical shape in the top view, then there is no combination of positions in the substrate 30 that would be rotationally symmetrical. In other words, there is no rotationally symmetrical position in the substrate 30 corresponding to a predetermined position. Therefore, the predetermined position of the substrate 30 can be easily identified by recognizing its outer edge. Of course, the substrate 30 can also be rotationally symmetrical in the top view. For example, the substrate 30 can be rotationally symmetrical in the top view when multiple rotationally symmetrical positions in the substrate 30 are identified without distinction.

[0060] <Action>

[0061] An example of operation for identifying a predetermined position of the wiring component 10 using the above-described pattern 40 will be described. Here, an example of operation for identifying a predetermined position of the wiring component 10 using general image recognition technology will be described.

[0062] First, the wiring component 10 is photographed from the thickness direction. The photographing area can be the entire wiring component 10, the entire substrate 30, or the portion of the substrate 30 that includes the pattern 40. For example, if the pattern 40 is an outer edge identification pattern 40, it is preferable to include at least the entire substrate 30 in the photographing area.

[0063] Next, pattern 40 is identified in the captured image. Pattern 40 can be identified, for example, by performing edge extraction processing on the captured image. Specifically, for example, when pattern 40 is an outer edge identification pattern 40, the contrast between the outer edge identification pattern 40 and the middle portion closer to the center in the captured image becomes greater. Therefore, in the captured image, the outer edge identification pattern 40 can be identified by extracting the portion with the larger contrast difference.

[0064] Next, the identified pattern 40 is used to identify the two-dimensional position of a predetermined location in the wiring component 10 related to the substrate 30. For example, by performing shape matching using the identified pattern, the two-dimensional position of the predetermined location in the wiring component 10 related to the substrate 30 can be identified. Specifically, when the pattern 40 is an outer edge identification pattern 40, by comparing the obtained outer edge identification pattern 40 with pre-stored data, the two-dimensional position of a portion of the outer edge identification pattern 40 in the wiring component 10, i.e., the two-dimensional position of the outer edge of the substrate 30 in the wiring component 10, can be identified. Therefore, the pattern 40 can also be regarded as a pattern that facilitates the detection of the position of at least a portion of the portion in the wiring component 10 related to the substrate 30 when shape matching is performed based on an image of the wiring component 10 taken from the thickness direction.

[0065] By identifying the two-dimensional position of the predetermined position in the wiring component 10 related to the substrate 30, the position of the part held by the robot or the like during the assembly operation (e.g., the position of the connector, the position of the clamp) can be determined based on the obtained two-dimensional position information, thereby enabling the smooth automatic assembly operation.

[0066] According to the wiring component 10 configured as described above, the predetermined position in the wiring component 10 can be easily identified by the pattern 40 formed on the wiring body 12. In addition, since the outer edge identification pattern 40 is formed as the pattern 40, contrast is easily generated in the outer edge of the substrate 30, thereby making it easy to identify the outer edge of the substrate 30.

[0067] Furthermore, since the rigidity of the wiring component 10 is increased by the cover 34, it is easy to maintain the shape of the portion associated with the substrate 30. Therefore, by using the pattern 40 to identify the position of a portion of the substrate 30, it is easy to determine any position within the substrate 30.

[0068] [Implementation Method 2]

[0069] The wiring components involved in Embodiment 2 will be described. Figure 3 This is a top view showing the wiring component 110 according to Embodiment 2. Furthermore, in the description of this embodiment, the same reference numerals are used for the same components as those described so far, and their descriptions are omitted. The same applies in the descriptions of the following embodiments.

[0070] In the wiring component 110 according to Embodiment 2, the pattern 140 is different from the pattern 40 in the wiring component 10 according to Embodiment 1. Specifically, a feature portion 140 is provided as the pattern 140. The feature portion 140 is a part of the wiring body 12 that presents an appearance inconsistent with other parts. The outer edge identification pattern 40 is used to identify the entire part related to the substrate 30, while the feature portion 140 is used to identify a part related to the substrate 130.

[0071] In this example, a shape-specific portion 140 is formed as a feature portion 140. The shape-specific portion 140 is a portion of the substrate 130 whose shape differs from the shapes of other portions. Furthermore, in Figure 3 In the example shown, a portion of the sheet 132 is shaped differently from the other portions, thus becoming a shape-specific part 140. Of course, a portion of the cover 34 could also be shaped differently from the other portions, thus becoming a shape-specific part 140.

[0072] The location of the shape-specific portion 140 is not particularly limited and can be formed at any location on the substrate 130. Here, the shape-specific portion 140 is formed on the outer edge of the substrate 130. Therefore, in the outer edge of the substrate 130, the shape of the shape-specific portion 140 is formed differently from the shape of other parts. In particular, the shape-specific portion 140 is formed at the corner of the substrate 130.

[0073] The shape-specific portion 140 is formed such that portions extending from two edges of the corner constituting the substrate 130 are connected. This prevents the shape-specific portion 140 from being obscured by bending. More specifically, in Figure 3 In the example shown, the shape-specific portion 140 is formed in the outer edge of the substrate 130 on the inner peripheral side of the corner where the strip-shaped portions 36a and 36b intersect and bend. The shape-specific portion 140 is formed such that a portion extending from the edge of the strip-shaped portion 36a is connected to a portion extending from the edge of the strip-shaped portion 36b.

[0074] The shape of the shape-distinct part 140 is not particularly limited; it can be formed into any shape as long as it differs from the other parts. Preferably, the shape of the shape-distinct part 140 is non-rotationally symmetrical in a top view. Figure 3 In the example shown, the shape feature 140 is formed as a square with a missing corner in the top view. The shape feature 140 can also be regarded as a stepped shape with continuous corners facing the same direction.

[0075] The size of the shape-specific part 140 is not particularly limited, as long as it is a recognizable size. For example, when using image processing to recognize the shape-specific part 140, the shape-specific part 140 can be set according to the resolution of the imaging unit, etc. For example, the shape-specific part 140 can be formed to a size smaller than or equal to the width of the substrate 130. In addition, the shape-specific part 140 can also be formed to a size smaller than or equal to the dimension of the parallel direction of the plurality of linear transmission members 20 (the interval between the two outermost linear transmission members 20).

[0076] Even when pattern 140 is feature 140, feature 140 can be identified using general image recognition technology, just as in the operation example described in Embodiment 1, thereby identifying the predetermined position of wiring component 110. In this case, when pattern 140 is feature 140, and the position of feature 140 can be deduced to some extent during shooting, it is not necessary to include the entire substrate 130 in the shooting range; only the area that includes at least the entire feature 140 needs to be included in the shooting range.

[0077] According to the wiring component 110, a predetermined position in the wiring component 110 can also be easily identified by the pattern 140 provided on the wiring body 112. Since the wiring component 110 has a feature portion 140 provided as a pattern 140, the portion having the feature portion 140 can be easily identified by recognizing the feature portion 140. Furthermore, since the feature portion 140 has a shape-specific portion 140 formed as a feature portion 140, the feature portion 140 can be formed by the shape of the substrate 130.

[0078] [Implementation Method 3]

[0079] The wiring components involved in Embodiment 3 will be described. Figure 4 This is a top view showing the wiring component 210 according to Embodiment 3.

[0080] In the wiring component 210 according to Embodiment 3, the feature portion 240 is different from the feature portion 140 in the wiring component 110 according to Embodiment 2. In this example, the feature portion 240 is a path-specific portion 240. In the path of the linear transmission component 20 in the substrate 230, the appearance of a portion of the path of the path-specific portion 240 is different from the appearance of other portions of the path.

[0081] In the path of the linear transmission member 20, the portion designated as the path-specific part 240 is not particularly limited; any portion whose appearance differs from that of other parts of the path can be designated as the path-specific part 240. Here, the curved portion in the linear transmission member 20 is designated as the path-specific part 240. In this case, it is preferable to designate the portion from the beginning of the curve to the end of the curve as the path-specific part 240.

[0082] Furthermore, in the path-specific section 240, parts of the same path can exist as long as the appearance of the path is different. For example, even if there are multiple parts of the same curved section in the linear transmission member 20, if only one part is visible and the others are all blocked by the cover 34, the visible part can be used as the path-specific section 240.

[0083] Here, a path identification aid is provided to make the path of the path-specific section 240 more noticeable than the path of other parts. In the path-specific section 240, the cover 234 is not provided, and the linear transmission member 20 is exposed. The cover 234 is provided outside the path-specific section 240, serving as a path identification aid. Alternatively, a transparent cover can be provided in the path-specific section 240, while opaque covers are provided in other parts, also serving as a path identification aid. Furthermore, in the absence of a cover, the sheet 32 ​​in the path-specific section 240 can be a different color from the linear transmission member 20, while in other parts the sheet 32 ​​can be the same color as the linear transmission member 20, serving as a path identification aid.

[0084] When the feature portion 240 is a path-specific portion 240, it is preferable that the color of the linear transport member 20 (the color of the covering layer 24) and the color of the substrate 230 (in) Figure 4 In the example shown, the color of sheet 32 ​​is different. In particular, the color of the linear transmission component 20 and the color of the substrate 230 are preferably set to have a greater contrast, such as white and black. As a result, the path-specific section 240 is easily identifiable.

[0085] According to the wiring component 210, a predetermined position in the wiring component 210 can also be easily identified by the feature portion 240, which is a pattern 240 formed on the wiring body 212. According to the wiring component 210, the feature portion 240 can be formed along the path of the linear transmission member 20. In addition, similar to the operation example described in Embodiment 1, the path feature portion 240 can be identified using general image recognition technology, thereby identifying the predetermined position of the wiring component 210.

[0086] [Implementation Method 4]

[0087] The wiring components involved in Embodiment 4 will be described. Figure 5 This is a top view showing the wiring component 310 according to Embodiment 4. Additionally, in Figure 5 In order to make the difference in color between the substrate 30 and the mark 340 easier to understand, a sandy shading line was applied to a portion of it.

[0088] In the wiring component 310 according to Embodiment 4, the feature portion 340 is different from the feature portions 140 and 240 in the wiring components 110 and 210 according to Embodiments 2 and 3. In this example, the feature portion 340 is a mark 340. The mark 340 is applied to a portion of the surface of the substrate 30.

[0089] The location where the mark 340 is applied is not particularly limited and can be applied to any location on the substrate 30. Here, the mark 340 is applied to the end of the substrate 30. More specifically, in Figure 5 In the example shown, mark 340 is applied to the end of the strip portion 36a opposite to the side intersecting with strip portion 36b in the substrate 30. For example, it is conceivable to apply mark 340 to a portion of the substrate 30 that remains planar in a direction orthogonal to the planar viewing direction. Therefore, mark 340 is less likely to tilt, thus reducing the likelihood of misidentification of mark 340. Figure 5 In the example shown, mark 340 is applied to the portion of the cover line transmission member 20 within the cover 34.

[0090] The shape of mark 340 is not particularly limited; it can be any shape as long as it differs from the other parts. Preferably, mark 340 is formed in a shape that is not rotationally symmetrical in a top view. Figure 3 In the example shown, mark 340 is formed as a square with a missing corner in the top view.

[0091] The size of the mark 340 is not particularly limited as long as it is a recognizable size. For example, when image processing is used to recognize the mark 340, the size of the mark 340 can be set according to the resolution of the imaging unit, etc. For example, the mark 340 can be formed to a size smaller than or equal to the width of the substrate 30. In addition, the mark 340 can also be formed to a size smaller than or equal to the dimension of the parallel direction of the plurality of linear transmission members 20 (the interval between the two outer linear transmission members 20).

[0092] The material of the mark 340 is not particularly limited. For example, the mark 340 can be made by coating the substrate 30 or by attaching a thin strip-shaped component that is narrower than the substrate 30.

[0093] According to the wiring component 310, a predetermined position in the wiring component 310 can also be easily identified by the feature portion 340, which is a pattern 340 formed on the wiring body 12. According to the wiring component 310, the feature portion 340 can be formed by marking 340 on the substrate 30. In addition, similar to the operation example described in Embodiment 1, the marking 340 can be identified by general image recognition technology, thereby identifying the predetermined position of the wiring component 310.

[0094] [Postscript]

[0095] This concludes the explanation of cases where the substrate includes a cover in wiring components, but this is not a mandatory structure. There are also cases where the substrate does not include a cover.

[0096] Furthermore, the case where the linear transmission component 20 is fixed on a sheet serving as a substrate in the wiring harness has been described, but this is not a necessary structure. For example, the linear conductor can also be fixed inside the substrate in the wiring harness. The wiring harness can also be a so-called FFC (flexible flat cable) formed by sandwiching multiple linear conductors between two thin films or by extruding resin material around multiple linear conductors.

[0097] Furthermore, this section has described the case where only one pattern is formed in a wiring component, but this is not a mandatory structure. Multiple patterns 40, 140, 240, and 340 can also be used in a single wiring component. In this case, multiple patterns 40, 140, 240, and 340 can be used in any combination.

[0098] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
