[0007] KR 10 2010 0 107 147 A discloses a wiring component with a cover plate, in which a double-sided adhesive element is attached to an outer surface of the cover plate for fastening to the target body. OVERVIEW OF THE INVENTION TASKS TO BE SOLVED BY THE INVENTION

[0008] In a wiring harness described in JP 2018-137208A, a case arises where an additional flat section is to be welded to a functional outer element. However, it may occur that welding the additional flat section to the functional outer element proves difficult. For example, it may be difficult to weld the additional flat section advantageously to the functional outer element if a welding device becomes entangled on a wire-shaped transmission element during the welding process.

[0009] Accordingly, the invention is based on the objective of providing a technique for advantageously welding a flat part, to which a wire-shaped transmission element is fixed, with another flat part. MEANS OF SOLVING THE TASK

[0010] A wiring component according to the present disclosure is a wiring component that has the features of claim 1. EFFECT OF INVENTION

[0011] According to the present disclosure, the flat part to which the wire-shaped transmission element is fixed can advantageously be welded to the further flat part.

Fig. Figure 8 is a rear view illustrating a modified example of the wiring component. FORMS OF EXECUTION OF THE INVENTION

[0012] First, embodiments of the present disclosure are listed and described.

[0013] A wiring component according to the present disclosure is designed as follows. (1) A wiring component according to the invention has the features of claim 1. (2) The welding position where the fixing flat and the cover flat are welded together may be located at least at both ends of a side of the main pipe that is laterally opposed in a longitudinal direction. Accordingly, the fixing flat and the cover flat are welded together at a position that lies on both sides of the main pipe. (3) The cover plate may have a branching cover section that overlaps a branching section in which some of the wire-shaped transmission elements branch off from the main line. Accordingly, the branching section is also covered by the cover plate. (4) Welding positions where the fixing flat and the cover flat are welded together in the branching cover section may be arranged at several positions surrounding the branching section. Accordingly, the fixing flat and the cover flat are firmly fixed together in the branching cover section. (5) The cover plate can be arranged section by section along a longitudinal direction of the fixing plate. This counteracts any increase in the weight of the wiring component caused by the provision of the cover plate. (6) The cover plate may also comprise a first flat section and a second flat section, which are arranged at intervals along the longitudinal direction of the fixing flat section. The first flat section may cover an area comprising a branching section in which some of the several wire-shaped transmission elements branch off from the main line. The second flat section may cover an area comprising a parallel section in which some of the wire-shaped transmission elements of the several wire-shaped transmission elements are arranged in parallel. Welding positions at which the second flat section and the fixing flat section are welded together may be arranged on both lateral sides of the parallel section. Accordingly, the first flat section and the second flat section may advantageously be welded to the fixing flat section. (7) The fixing flat part may also have a first route section and a second route section branching off from the first route section; some wire-shaped transmission elements of the multiple wire-shaped transmission elements may branch off from other wire-shaped transmission elements in the first route section and be fixed to the second route section; and a section of the covering flat part covering a branch section may cover the first route section but not the second route section. Accordingly, the area in which the section covering the branch is arranged in the fixing flat part is reduced. (8) The fixing flat part may have a first route section and a second route section branching off from the first route section; some of the wire-shaped transmission elements may branch off from other wire-shaped transmission elements in the first route section and run along the second route section; and a section of the cover flat part covering a branching section may be branched in such a way that it covers both the first route section and the second route section. Accordingly, the section of the cover flat part covering the branch also has a branched shape. (9) Some of the wire-shaped transmission elements of the multiple wire-shaped transmission elements can branch off from other wire-shaped transmission elements on the fixing flat in a branching section and extend outwards from a side edge of the fixing flat. Accordingly, the area in which the fixing flat and the cover flat are arranged on the wire-shaped transmission element is reduced and an increase in the weight of the wiring component can be prevented. (10) The cover plate may have a higher stiffness than the fixing plate. Accordingly, the shape of the wiring component is maintained by the cover plate. (11) A double-sided adhesive element is attached to an outer surface of the cover plate and the double-sided adhesive element overlaps a branching section. Accordingly, the double-sided adhesive element is arranged over a comparatively large area. (12) The adhesive force between the outer surface and the double-sided adhesive element is greater than the adhesive force between the other main surface and the double-sided adhesive element. Accordingly, the strength of the fixation is higher in a case where the wiring component is attached and fixed to a target body by means of an adhesive than in a case where an adhesive is provided directly on the fixing surface. DETAILS OF EXAMPLES OF EXECUTION

[0014] With reference to the drawings, specific examples of a wiring component of the present disclosure are described below. The present disclosure is not limited to these examples, but is defined by the claims, and it is intended that equivalent meanings and all variations within the scope of the claims are included. Example of implementation

[0015] The following describes a wiring component according to an exemplary embodiment. Fig. Figure 1 is a schematic top view illustrating a wiring component 10 according to the embodiment. Fig. Figure 2 is a schematic rear view illustrating the wiring component 10 according to the embodiment. Fig. Figure 3 is a schematic enlarged view of an area A1 in Fig. 2. Fig. Figure 4 is a schematic enlarged view of an area A2 in Fig. 2. Fig. Figure 5 is a schematic enlarged view of an A3 area in Fig. 2. Fig. 6 is a schematic cross-sectional view along a line VI-VI in Fig. 4.

[0016] The wiring component 10 comprises a wiring body 12 and a cover plate 40. The wiring component 10 also has a double-sided adhesive element 50. The wiring component 10 is attached to an adhesive target body 80 by means of the double-sided adhesive element 50. The wiring component 10 is, for example, installed in a vehicle. The adhesive target body 80 is an element to which the wiring component 10 is to be fixed in a vehicle. The adhesive target body 80 is, for example, a body frame, a body panel, or an interior trim panel in the vehicle.

[0017] The wiring body 12 comprises a wire-shaped transmission element 20 and a fixing flat part 30. It contains at least one wire-shaped transmission element 20. In the present example, several wire-shaped transmission elements 20 are included. Each wire-shaped transmission element 20 is, for example, a wire-shaped element that transmits electrical energy or light. The fixing flat part 30 is formed as a whole in a flat shape. The several wire-shaped transmission elements 20 are fixed to the fixing flat part 30, thus holding the wiring body 12 in a flat state. In the Fig. In the illustrated example 6, several wire-shaped transmission elements 20 with the same diameter and structure are arranged on a fixing flat 30. However, the diameter and structure of each of the several wire-shaped transmission elements 20 can be advantageously defined; thus, for example, wire-shaped transmission elements 20 with different diameters and different structures can be arranged on the same fixing flat 30.

[0018] It is assumed that the several wire-shaped transmission elements 20 are elements that connect components in a vehicle. For example, a connector C is provided at one end section of the wire-shaped transmission elements 20. This connector C is connected to a connector provided in the counterpart component, thus connecting the wire-shaped transmission element 20 to the counterpart component. That is, the present wiring component 10 is used as a wiring component 10 that, for example, electrically connects (or connects in such a way that they can communicate optically) components of different types in a vehicle. The connector C can be fixed to the fixing flat 30.

[0019] The routes of the multiple wire-shaped transmission elements 20 are configured according to the position of a component to which the wire-shaped transmission elements 20 are to be connected. The multiple wire-shaped transmission elements 20 are fixed to the fixing flat 30, thus maintaining a shape that follows a cabling route corresponding to the position of a component that is a connection destination for the respective wire-shaped transmission element 20. The multiple wire-shaped transmission elements 20 can be fixed to the fixing flat 30 in a state where a branch line diverges from a main line. The fixing flat 30 can also be configured in a shape where a section to which the branch line is fixed diverges from a section to which the main line is fixed.In this case, several wire-shaped transmission elements 20 branch out on the fixing flat part 30. A section at which some of the wire-shaped transmission elements 20 branch off from the other wire-shaped transmission elements 20 of the several wire-shaped transmission elements 20 is called a branching section DP. As in . Fig. 3 and Fig. As illustrated in Figure 4, in the present example there are two branching sections DP1 and DP2 on the fixing flat part 30.

[0020] The fixing flat 30 has a first route section 31 and a second route section 32 at positions corresponding to branch sections DP1 and DP2. The second route section 32 is a section that branches off from the first route section 31. Some of the multiple wire-shaped transmission elements 20 branch off from the other wire-shaped transmission elements 20 in the first route section 31 and are fixed to the second route section 32. The first route section is a section to which the main line is fixed. The second route section is a section to which the branch line is fixed. The main line has a branch line that branches off from a section of the main line. The main line has multiple wire-shaped transmission elements as the starting point of a branch of the branch line.The main line can be understood, for example, as one or more wire-shaped transmission elements with a greater weight than in the branch line, or as a greater number of wire-shaped transmission elements than in the branch line. The main line can also be understood as one or more wire-shaped transmission elements that are longer than the branch line.

[0021] The respective wire-shaped transmission element 20 comprises a transmission conductor 22 and a sheathing layer 24. The transmission conductor 22 transmits, for example, electrical energy or light. The sheathing layer 24 covers the transmission conductor 22. The respective wire-shaped transmission element 20 can be, for example, an ordinary cable with a conductor and a sheathing layer around the conductor, or it can be a shielded cable, a twisted-pair cable, an enamelled wire, a nickel-chromium wire, or an optical fiber cable.

[0022] The electrical energy-transmitting wire-shaped transmission elements 20 can be signal lines of various types or power supply lines of various types. Some of the electrical energy-transmitting wire-shaped transmission elements 20 can, for example, be used as an antenna or coil that transmits a signal or electrical energy to or from a location.

[0023] The respective wire-shaped transmission element 20 can be a single wire-shaped object or a composite object made up of several wire-shaped objects (a twisted line or a cable formed by several wire-shaped objects enclosed by a sheath).

[0024] The respective wire-shaped transmission element 20 is fixed to a main surface of the fixing flat part 30. The fixing flat part 30 can be a plastic flat part. For example, the fixing flat part 30 can be made of a plastic such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET). The fixing flat part 30 can be a flat part with a uniformly filled cross-section. The fixing flat part 30 can also be a fibrous material such as a braided fabric, a woven fabric, or a nonwoven fabric. The fixing flat part 30 can also be, for example, a foam flat part. The fixing flat part 30 can have a single-layer structure or a multi-layer structure. The fixing flat part 30 can have a metal layer.

[0025] In this case, the fixing flat part 30 has a first layer 33 and a second layer 34 stacked on top of each other. The fixing flat part 30 has a double-layer structure. The fixing flat part 30 has no further layers besides the first layer 33 and the second layer 34. However, the fixing flat part 30 can also have a structure of three or more layers. The fixing flat part 30 can have a layer that is different from the first layer 33 and the second layer 34.

[0026] The first layer 33 can be a plastic layer with a uniformly filled cross-section. The wire-shaped transmission element 20 is fixed to the first layer 33. The first layer 33 is a fixing layer. The plastic material of the first layer 33 is, for example, the same as that of the sheathing layer 24. A surface of the first layer 33 is a major surface of the fixing flat part 30.

[0027] The second layer 34 is a fibrous material layer. The cover plate 40 is fixed to the second layer 34. One surface of the second layer 34 is the other main surface of the fixing plate 30.

[0028] The first layer 33 and the second layer 34 are fixed to one another, with the other surface of the first layer 33 and the other surface of the second layer 34 being in contact with each other. The fixation state in which the first layer 33 and the second layer 34 are fixed to one another is not specifically restricted; however, fixation by welding or bonding is preferred. Specifically, the first layer 33, which is a plastic layer, and the second layer 34, which is a fiber material layer, are preferably fixed by the plastic of the plastic layer or by an adhesive that penetrates the interfiber space of the fiber material layer. Such a configuration creates the so-called anchoring effect, thus firmly fixing the first layer 33 and the second layer 34 to one another. In the present case, the first layer 33 and the second layer 34 are welded together.This means that the plastic of the first layer 33, which is a plastic layer, penetrates the interfiber space of the second layer 34, which is a fiber material layer, in a liquid state and is then cured. Accordingly, a state is maintained in which the plastic of the plastic layer penetrates the interfiber space of the fiber material layer, and the first layer 33 and the second layer 34 are fixed to one another. The first layer 33 and the second layer 34 are of the same size. One layer of the first layer 33 and the second layer 34 can also be larger than the other. The first layer 33 and the second layer 34 are fixed to one another over the entire area where they are in contact. The first layer 33 and the second layer 34 can also be fixed to one another only in a portion of the area where they are in contact.

[0029] The fixing flat part 30 can be a flexible element. For example, the first layer 33 is a plastic layer with a uniformly filled cross-section made of a flexible plastic such as soft PVC, the second layer 34 is a nonwoven fabric made of PET, and the fixing flat part 30 is a flexible element. The fixing flat part 30 can, for example, be plastic so that it can follow bends in the wire-shaped transmission element 20. That is, the cable body 12 can also be bendable in one thickness direction (bendable in such a way that a fold line follows the main surface of the fixing flat part 30).

[0030] A fixing structure by which the respective wire-shaped transmission element 20 is fixed to the fixing flat part 30 is not specifically restricted, as long as the wire-shaped transmission element 20 is fixed to the fixing flat part 30. The fixed state can be achieved by fixing to contact surfaces or by fixing without involving the contact surfaces, or both types of fixing can be combined. In this context, "fixation to contact surfaces" means that a section in which the respective wire-shaped transmission element 20 and the fixing flat part 30 are in contact with each other is fixed by a material bond.“Fixation without contact surface involvement” means a state that differs from “fixation at contact surfaces” and in which a sewing thread, a cover, or an adhesive tape presses the wire-shaped transmission element 20 against the fixing flat part 30 or encompasses the wire-shaped transmission element 20 and the fixing flat part 30 from both sides to hold them in a fixed state. In the following description, the wire-shaped transmission elements 20 and the fixing flat part 30 are in the state of “fixation at contact surfaces”.

[0031] For fixing to contact surfaces, indirect fixing, direct fixing, or both fixing methods can be used in different areas. In this context, "indirect fixing to contact surfaces" means that the respective wire-shaped transfer element 20 and the fixing flat part 30 are indirectly fixed to one another via an intervening adhesive, an adhesion agent, or a double-sided adhesive tape. "Direct fixing to contact surfaces" means that the respective wire-shaped transfer element 20 and the fixing flat part 30 are directly fixed to one another without a separately provided adhesive or the like being placed between them.In the case of direct fixation to contact surfaces, it is conceivable, for example, that plastic contained in the respective wire-shaped transmission element 20 and / or the fixing flat part 30 is liquefied and the respective wire-shaped transmission element 20 and the fixing flat part 30 are thereby fixed to each other in a materially bonded manner.

[0032] In the formation of such a state of direct fixation at contact surfaces, it is conceivable that the plastic is liquefied, for example, by heat or by a solvent. That is to say, the state of direct fixation at contact surfaces can be a state of direct fixation at contact surfaces achieved by heat or a state of direct fixation at contact surfaces achieved by a solvent. Direct fixation at contact surfaces achieved by heat is preferred.

[0033] Possible means of establishing the state of direct fixation to the contact surfaces are not specifically limited; known methods such as welding, fusion, and fusion joining can be used. For example, if the state of direct fixation to the contact surfaces is achieved by welding, various welding agents such as ultrasonic welding, high-pressure welding, hot air welding, and high-frequency welding can be used. When the state of direct fixation to the contact surfaces is established by these means, the respective wire-shaped transmission element 20 and the fixing flat part 30 are in the state of direct fixation to the contact surfaces brought about by these means.

[0034] In particular, if the state of direct fixation to contact surfaces is formed, for example by ultrasonic welding, the respective wire-shaped transmission element 20 and the fixing flat part 30 are in the state of direct fixation to contact surfaces caused by ultrasonic welding.

[0035] In the following description, the wire-shaped transmission elements 20 and the fixing flat part 30 are in the state of direct fixation to their contact surfaces.

[0036] Each of the multiple wire-shaped transmission elements 20 can be fixed to the fixing flat part 30 at several positions at intervals along its longitudinal direction. Each of the multiple wire-shaped transmission elements 20 can be fixed to the fixing flat part 30 continuously along its entire longitudinal direction.

[0037] The cover plate 40 covers the other main surface of the fixing plate 30. The cover plate 40 is fixed to the other main surface of the fixing plate 30. The cover plate 40 is fixed to a section of the fixing plate 30 that is offset from (spaced a predetermined distance from) a section to which the wire-shaped transmission element 20 is fixed.

[0038] The cover plate 40 can completely or partially overlap the fixing plate 30. The cover plate 40 can be made of the same material as the fixing plate 30 or of a different material. The cover plate 40 can be a plastic plate. For example, the cover plate 40 can be made of a plastic such as PVC, PE, PP, or PET, in the same way as the fixing plate 30.

[0039] A flat part consisting of the fixing flat part 30 and the cover flat part 40 can have a higher stiffness than the other of the two. In this case, the cover flat part 40 is designed with a higher stiffness than the fixing flat part 30. For example, the cover flat part 40 is made of a rigid plastic material such as rigid PVC, nylon, PET, or PP, so that it has a uniformly filled cross-section. It is also possible that the cover flat part 40 can prevent bending of the cable body 12. In this case, it is described that the cover flat part 40 has a single-layer structure consisting of a single plastic layer. The plastic layer has a higher stiffness than the fixing flat part 30. The cover flat part 40 can also have a multi-layer structure.

[0040] The cover plate 40 and the fixing plate 30 are fixed to one another, with a surface of the plastic layer of the cover plate 40 and a surface of the fiber material layer of the fixing plate 30 in contact with each other. The cover plate 40 and the fixing plate 30 are fixed to one another by welding. The state of fixation of the cover plate 40 and the fixing plate 30 is not specifically limited as long as they are fixed by welding; examples include the following three states. The cover plate 40 and the fixing plate 30 can be welded to one another according to any one of the following three states, and it is preferred that the cover plate 40 and / or the fixing plate 30 be melted so that the cover plate 40 and the fixing plate 30 can be fixed to one another.

[0041] The first state is as follows: In the plastic layer of the cover plate 40 and the fiber layer of the fixing plate 30, the plastic of the cover plate 40's plastic layer is heated and melted, for example, by ultrasonic welding, so that it comes into contact with the fixing plate 30 and adheres to it, thus welding the cover plate 40 and the fixing plate 30 together. In this process, the plastic of the plastic layer in the cover plate 40 can either only be in contact with the surface of the fiber layer or it can also penetrate the fiber layer. If the plastic of the plastic layer in the cover plate 40 penetrates the fiber space of the fiber layer and is fixed to it, this configuration creates the so-called anchoring effect, thus firmly fixing the cover plate 40 and the fixing plate 30 together.This means that the plastic of the plastic layer in the cover flat part 40, in its liquid state, penetrates the interfiber space of the fiber material layer in the fixing flat part 30 and is then cured. Accordingly, a state is maintained in which the plastic of the plastic layer in the cover flat part 40 penetrates the interfiber space of the fiber material layer in the fixing flat part 30, and the cover flat part 40 and the fixing flat part 30 are fixed to one another.

[0042] The second state is as follows: The plastic of the fixing layer in the fixing flat part 30 is melted and penetrates the fiber material layer. Then the plastic of the fixing layer, which has penetrated the fiber material layer, comes into contact with the surface of the cover flat part 40 and adheres to it, thereby welding the cover flat part 40 and the fixing flat part 30 together.

[0043] The third state is as follows: The plastic forming the cover plate 40 is melted and penetrates the fiber layer in the fixing plate 30. The plastic of the fixing layer in the fixing plate 30 is also melted and penetrates the fiber layer. The plastic of the cover plate 40 within the fiber layer and the plastic of the fixing plate 30 then come into contact and adhere to each other, thus welding the cover plate 40 and the fixing plate 30 together. In this third embodiment, the plastic forming the cover plate 40 penetrates the fiber layer in the fixing plate 30; this configuration thus creates the so-called anchoring effect and firmly fixes the cover plate 40 and the fixing plate 30.

[0044] The cover plate 40 is provided in sections along a longitudinal direction of the fixing plate 30. The cover plate 40 comprises several flat plate sections 41, 42, 43, and 44. Each of the flat plate sections 41, 42, 43, and 44 covers only a partial section of the fixing plate 30 along the longitudinal direction. The flat plate sections 41, 42, 43, and 44 are provided at intervals along the longitudinal direction of the fixing plate 30. The cover plate 40 has a branching cover section. The branching cover section covers an area that includes the branching sections DP1 and DP2. In this case, the flat plate sections 41 and 42 cover the branching sections DP1 and DP2, respectively. The flat plate sections 41 and 42 are each branching cover sections. The cover plate 40 may also not have a branching cover section. This means that the cover plate 40 can cover a side that is closer to the terminal device than the branching section DP.

[0045] The flat sections 41, 42, 43, and 44 are each rectangular, although concave polygonal, circular, or oval shapes are also possible. Each of the flat sections 41, 42, 43, and 44 has an area that covers a different portion of the fixing flat section 30. Flat sections 41 and 42 are central sections of the fixing flat section 30 and are located in branch sections DP1 and DP2. Flat section 43 is located at an end section of the fixing flat section 30. Flat section 44 is a central section of the fixing flat section 30 and is located in a section separate from branch sections DP1 and DP2.

[0046] The flat section 41 is provided in the branching section DP1. Branching section DP1 is a section in which the several wire-shaped transmission elements 20 branch into four sections. Four branch lines extend from a branching point in branching section DP1. Among the four branch lines, two branch lines are continuously connected m across the branching point and are perpendicular to each other. The angle between the two branch lines continuously connected via the branching point need not be a right angle.

[0047] As in Fig. Figure 3 illustrates a position where the flat section 41 is welded to the fixing flat section 30. This position is located between two branch lines that are continuously connected via the branch point; that is, it is located in a free corner whose edges are formed by the two branch lines continuously connected via the branch point. Accordingly, a welding position WP1 is provided in the flat section 41, which is the branch cover section welded to the fixing flat section 30, at a position that avoids the branch section DP1. The flat section 41 is welded to the fixing flat section 30 at four corner positions. The four welding positions WP1, where the flat section 41 and the fixing flat section 30 are welded together, are located at positions surrounding the branch section DP1.Accordingly, a welding position WP1 is provided at several positions in the branch cover section welded to the fixing flat part 30, surrounding the branch section DP1. However, only a single welding position WP1 may also be provided in the branch cover section welded to the fixing flat part 30. It is sufficient that the welding position WP1 is provided at least on one lateral side of the main line with respect to a longitudinal direction and is positioned away from the branch line. Preferably, the welding position WP1 is provided at least on both lateral sides of the main line with respect to the longitudinal direction.

[0048] As in Fig. As illustrated in Figure 4, the flat section 42 is provided in the branching section DP2. Branching section DP2 is a section in which the multiple wire-shaped transmission elements 20 branch into three sections. Three branch lines extend from a branching point in branching section DP2. Two of the three branch lines run in opposite directions, and the remaining branch line runs in a direction that intersects the directions in which the two branch lines run. This can also be understood as the branch line branching off from the main line, which runs in one direction in branching section DP2. The main line and the branch line are perpendicular to each other. However, the angle between the main line and the branch line need not be a right angle.

[0049] The flat section 42 is welded to the fixing flat section 30 laterally, for example, to the wire-shaped transmission elements 20. Accordingly, the welding positions WP2 and WP3 in the flat section 42, which is the branching cover section welded to the fixing flat section 30, are located at a position that avoids the branching section DP2. The flat section 42 and the fixing flat section 30 are welded together at three positions. The three welding positions WP2 and WP3, at which the flat section 42 and the fixing flat section 30 are welded together, are located at positions surrounding the branching section DP2. Accordingly, the welding positions WP2 and WP3 in the branching cover section welded to the fixing flat section 30 are located at several positions surrounding the branching section DP2.The welding positions WP2 and WP3 in the branch cover section welded to the fixing flat part 30 can be provided at a single location. It is sufficient that the welding positions WP2 and WP3 are provided at least on one lateral side of the main line with respect to the longitudinal direction and are offset from the branch line. Preferably, the welding positions WP2 and WP3 are provided at least on both lateral sides of the main line with respect to the longitudinal direction. As in . Fig. As illustrated in Figure 4, a welding position WP3 on one side of the main line (a side where the branch line does not run) can be larger than the two welding positions WP2 on the two sides of the branch line.

[0050] As in Fig. As illustrated in Figure 5, a respective flat section 43 is provided at all of the several (in this case, five) end sections of the fixing flat section 30. The flat section 43 need not be provided at all of the several end sections of the fixing flat section 30. A respective flat section 43 can also be provided at only some of the several end sections of the fixing flat section 30. In this example, the condition in which the flat section 43 is provided at the end section of the fixing flat section 30 means that an end edge of the flat section 43 and an end edge of the fixing flat section 30 are at most 20 mm apart in a longitudinal direction.

[0051] The flat section 43 is welded to the fixing flat section 30 laterally, for example, to the wire-shaped transmission elements 20. The flat section 43 and the fixing flat section 30 are welded together at two positions. Two welding positions WP4, at which the flat section 43 and the fixing flat section 30 are welded together, are located on both lateral sides of the wire-shaped transmission elements 20. One of the two welding positions WP4, at which the flat section 43 and the fixing flat section 30 are welded together, is located in each of the two side edge sections of the fixing flat section 30.

[0052] The flat section 44 is provided on a central section of the fixing flat section 30, which runs along one direction. The flat section 44 is welded to the fixing flat section 30 laterally to the wire-shaped transmission elements 20 in the same manner as the flat section 43.

[0053] The flat sections 41 and 42 cover an area encompassing the branching sections DP1 and DP2. Flat sections 41 and 42 are fixed to the fixing flat section 30 at a position that avoids branching sections DP1 and DP2. Flat sections 43 and 44 cover an area encompassing a parallel section. The parallel section is a section in which at least some of the multiple wire-shaped transmission elements 20 are arranged parallel to one another. Welding positions, at which the flat sections 43, 44, and the fixing flat section 30 are welded together, are provided on both lateral sides of the parallel section. Accordingly, flat sections 41 and 42 are examples of a first flat section. Flat sections 43 and 44 are examples of a second flat section.

[0054] A double-sided adhesive element 50 is attached to the cover plate 40. The double-sided adhesive element 50 has two surfaces, both of which are planar and possess adhesive properties. The double-sided adhesive element 50 is an element that exhibits adhesive properties in a section that is in contact with the cover plate 40 and also in a section opposite it. The double-sided adhesive element 50 adheres to an outer surface of the cover plate 40 (a surface on one side opposite a surface fixed to the wiring body 12) and is planar. An outer surface of the double-sided adhesive element 50 adheres to the target body 80. An adhesive element can be provided on both surfaces of a carrier material flat part of the double-sided adhesive element 50. However, the double-sided adhesive element 50 can also have no carrier material flat part.

[0055] An area in which the double-sided adhesive element 50 is provided for the wiring body 12 is suitably configured. In the present example, a double-sided adhesive element 50 is provided on the entire outer surface of each of the flat sections 41, 42, 43, and 44. Accordingly, each double-sided adhesive element 50 is rectangular in shape to correspond to the outer shape of the respective flat sections 41, 42, 43, and 44. The respective double-sided adhesive element 50 can, for example, have a concave polygonal, circular, or oval shape. The respective double-sided adhesive element 50 can also be a different shape than the outer shape of the respective flat sections 41, 42, 43, and 44.For example, the respective double-sided adhesive element 50 can be provided in such a way that it has a frame-like shape that follows an outer edge of the respective flat section sections 41, 42, 43 and 44. If the cover flat section 40 is a large flat section, such as the fixing flat section 30, then a respective double-sided adhesive element 50 is preferably provided in a section of the cover flat section 40.

[0056] A surface of the cover plate 40 that is in contact with the double-sided adhesive element 50 is designated as the first contact surface CS1. A surface of the fixing plate 30 that is in contact with the cover plate 40 is designated as the second contact surface CS2. The adhesive force between the first contact surface CS1 and the double-sided adhesive element 50 is greater than the adhesive force between the second contact surface CS2 and the double-sided adhesive element 50 when the double-sided adhesive element 50 is positioned at the second contact surface CS2. The adhesive force can be evaluated, for example, using the results of separately conducted, identical peel tests (for example, tests according to JIS K6854).

[0057] If the section of the cover plate 40 that covers the fixing plate 30 is only partially fixed to the fixing plate 30, the double-sided adhesive element 50 is provided on a partial section of the fixing plate 30 that is covered by the cover plate 40 but not fixed to it, so that the adhesive force between the second contact surface CS2 and the double-sided adhesive element 50 can be measured. If the entire section of the cover plate 40 that covers the fixing plate 30 is fixed to the fixing plate 30, the section of the fixing plate 30 that is not covered by the cover plate 40 can also be considered the second contact surface CS2.That is, when the entire section of the cover flat 40 covering the fixing flat 30 is fixed to the fixing flat 30, the double-sided adhesive element 50 is provided on a section of the fixing flat 30 that is not covered by the cover flat 40, so that the adhesion force between the second contact surface CS2 and the double-sided adhesive element 50 can be measured.

[0058] As described above, the cover plate 40 has a single-layer structure formed by the plastic with a uniformly filled cross-section. The cover plate 40 is fixed to the second layer 34, which is the fiber material layer in the fixing plate 30, which has a double-layer structure formed by the first layer 33 and the second layer 34. Thus, the first contact surface CS1 is a surface of the plastic layer with a uniformly filled cross-section. The second contact surface CS2 is a surface of the fiber material layer. Accordingly, if a double-sided adhesive element 50 of the same size is provided at both the first contact surface CS1 and the second contact surface CS2, the effective contact area of ​​the contact between the first contact surface CS1 and the double-sided adhesive element 50 is larger than the effective contact area of ​​the contact between the second contact surface CS2 and the double-sided adhesive element 50.Accordingly, a design is achieved in a simple manner in which the adhesive force between the first contact surface CS1 and the double-sided adhesive element 50 is greater than the adhesive force between the second contact surface CS2 and the double-sided adhesive element 50.

[0059] Specifically, the surface of the fiber layer exhibits minute irregularities caused by the orientation of the multiple fibers (for example, gaps between the fibers or fiber bends). When the double-sided adhesive element 50 is applied to the surface of the fiber layer, it is in contact with the raised sections, but not with the recessed sections of the irregularities. Thus, the effective contact area between the double-sided adhesive element 50 and the fiber layer is smaller than the size of the double-sided adhesive element 50. Meanwhile, the surface of the plastic layer with a uniformly filled cross-section exhibits fewer irregularities than the fiber layer.Therefore, the effective contact area of ​​the actual contact between the double-sided adhesive element 50 and the plastic layer with a uniformly filled cross-section is equal to or slightly smaller than the size of the double-sided adhesive element 50. Thus, the effective contact area of ​​the contact between the first contact surface CS1 and the double-sided adhesive element 50 is larger than the effective contact area of ​​the contact between the second contact surface CS2 and the double-sided adhesive element 50.

[0060] Fig. Figure 7 is an explanatory diagram illustrating the wiring component 10 that is attached to the adhesive target body 80.

[0061] In this case, the cover plate 40 has a higher stiffness than the fixing plate 30. Thus, in a section where the cover plate 40 is provided, bending of the wiring component 10 caused by its own weight is prevented. Therefore, the wiring component 10 is secured in a simple manner, as described in Fig. Figure 7 illustrates the section where the cover plate 40 is provided, held in a flat form. As a result, the double-sided adhesive element 50 can be easily attached to the adhesive target body 80.

[0062] It is also conceivable that the fixing flat part 30 and the cover flat part 40 are welded together after the wire-shaped transmission element 20 has been fixed to the fixing flat part 30. In this case as well, according to the wiring component 10, the welding positions WP1, WP2, and WP3 are provided in the branch cover section welded to the fixing flat part 30 at positions further away from (away from) the branch sections DP1 and DP2. This prevents a welding device from becoming entangled with the wire-shaped transmission elements 20 when the fixing flat part 30 is welded to the cover flat part 40. Accordingly, the further cover flat part 40 can advantageously be welded to the fixing flat part 30 to which the wire-shaped transmission elements 20 are fixed.

[0063] The welding positions WP1, WP2, and WP3 in the branch cover section welded to the fixing flat 30 are provided at several positions surrounding the branch sections DP1 and DP2. Accordingly, the fixing flat 30 and the cover flat 40 are firmly fixed to each other in the branch cover section.

[0064] The cover plate 40 is provided section by section along the longitudinal direction of the fixing plate 30. This counteracts any increase in the weight of the wiring component 10 caused by the provision of the cover plate 40.

[0065] The cover plate 40 comprises the flat sections 41 and 42 as the first flat section and the flat sections 43 and 44 as the second flat section. The first flat section is fixed to the fixing flat section 30 at a position that avoids the branching sections DP1 and DP2. The second flat section is fixed to the fixing flat section 30 at a position that avoids the parallel section. Accordingly, the first and second flat sections can advantageously be welded to the fixing flat section.

[0066] The fixing flat section 30 has the first route section 31 and the second route section 32. The branching cover section covers the first route section 31, but not the second route section 32. Accordingly, the area in which the branching cover section is provided in the fixing flat section 30 is reduced in size.

[0067] The cover plate 40 has a higher rigidity than the fixing plate 30. Accordingly, the shape of the wiring component 10 is maintained by the cover plate 40. Accordingly, the section of the wiring component 10 to which the cover plate 40 is fixed is easily kept flat. Accordingly, the double-sided adhesive element 50 is also easily kept flat, and the double-sided adhesive element 50 can be easily attached to the adhesive target body 80.

[0068] The double-sided adhesive element 50 is attached to an outer surface of the cover plate 40, and the double-sided adhesive element 50 overlaps the branch sections DP1 and DP2. Accordingly, the double-sided adhesive element 50 is provided over a comparatively large area. The adhesive force between the outer surface of the cover plate 40 and the double-sided adhesive element 50 is greater than the adhesive force between the other main surface of the fixing plate 30 and the double-sided adhesive element 50. Therefore, the bond strength is higher when the wiring component 10 is attached to and fixed to the target body 80 by the double-sided adhesive element 50 than when the double-sided adhesive element 50 is provided on the fixing plate 30. Variation example

[0069] Fig. Figure 8 is a rear view illustrating a modified example of the wiring component 10.

[0070] The shapes of a fixing flat part 130 and a flat part section 141 in the branching section DP1 are shown in the Fig. 8 illustrated cabling component 110 differently.

[0071] The number of branches of the fixing flat section 130 in branching section DP1 is less than the number of branches of the multiple wire-shaped transmission elements 20. The multiple wire-shaped transmission elements 20 are branched into four sections, while the fixing flat section 130 is branched into three sections. Only a single second route section 32 branches off from the first route section 31. In one direction of a branch line, the fixing flat section 130 is not elongated. This branch line extends from a lateral edge of the fixing flat section 130. It is also possible that the fixing flat section 130 does not branch in branching sections DP1 and DP2.

[0072] The flat section 141 branches in the same direction as the fixing flat section 130. In this case, the flat section 141 branches into three sections. The flat section 141, which is the branching cover section, is branched in such a way that it covers both the first route section 31 and the second route section 32. The flat section 141 is in the shape of a concave octagon with two re-entrant angles. The flat section 42 can, like the flat section 141, be in a shape that branches into three sections. If the fixing flat section 30 branches into four sections in the branching section DP1, the flat section 41 can be in a shape that branches into four sections.

[0073] The flat section 141 and the fixing flat section 130 are welded together at four positions. Two weld positions WP5, selected from the four weld positions WP5 and WP6, are located on sections of the flat section 141 that each have a re-entrant angle. Each weld position WP5 is positioned to extend along two sides forming the re-entrant angle. Each weld position WP5 is L-shaped. The remaining two weld positions WP6, selected from the four weld positions WP5 and WP6, are elongated on one side. Weld positions WP5 and WP6 are each located in an area larger than weld position WP1. This increases the strength of the connection between the flat section 141 and the fixing flat section 130.

[0074] The double-sided adhesive element 50 can be provided along the entire flat section 141. In the same manner as in Fig.5 The double-sided adhesive element 50 can also be provided in a rectangular shape in a section that includes the branching point.

[0075] According to the cabling component 110 of the present example, the flat section 141 covers both the first route section 31 and the second route section 32. Accordingly, the flat section 141, which is the branch cover section, also has a branched shape. If the flat section 141 has a higher stiffness than the fixing flat section 30, a route of an initial section of the branch line can now be controlled by the section of the flat section 141 that covers the second route section 32.

[0076] In the branching section DP1, some of the multiple wire-shaped transmission elements 20 branch off from the other wire-shaped transmission elements 20 on the fixing flat 130 and extend outwards from the side edge of the fixing flat 130. Accordingly, the area in which the fixing flat 130 and the cover flat 40 are provided on the wire-shaped transmission elements 20 is reduced, and an increase in the weight of the wiring component 110 can be prevented.

[0077] Furthermore, the description of the exemplary embodiment shows the double-sided adhesive element 50 provided on the outer surface of the cover plate 40; however, this is not mandatory. It is also possible that no double-sided adhesive element 50 is provided on the outer surface of the cover plate 40. In this case, it is conceivable that the wiring component is snapped and fixed to an adhesive target body by a snap-in element, such as a clamp.

[0078] In the description of the exemplary embodiment, the cover plate 40 has a higher stiffness than the fixing plate 30; however, this is not mandatory. The cover plate 40 can have the same or a lower stiffness than the fixing plate 30. The cover plate 40 can, for example, be a film.

[0079] In the description of the exemplary embodiment, several flat sections 41, 42, 43, and 44 are provided, but this is not mandatory. The flat sections 41, 42, 43, and 44 can be omitted or added as needed. Preferably, at least one of the flat sections 41, 42, 43, and 44 is provided.

[0080] In the description of the exemplary embodiment, the first contact surface CS1 is the surface of the plastic layer with a uniformly filled cross-section, and the second contact surface CS2 is the surface of the fiber material layer. This results in a greater adhesive force between the first contact surface CS1 and the double-sided adhesive element 50 than between the second contact surface CS2 and the double-sided adhesive element 50, although this is not mandatory. Other combinations are also possible for the first contact surface CS1 and the second contact surface CS2. For example, both the first contact surface CS1 and the second contact surface CS2 can be surfaces of plastic layers, each with a uniformly filled cross-section, with the first contact surface CS1 being flatter than the second contact surface CS2.This means that the first contact surface CS1 can have fewer surface irregularities (a lower surface roughness) than the second contact surface CS2. For example, it is possible for a material forming the first contact surface CS1 to be more compatible with the double-sided adhesive element 50 than a material forming the second contact surface CS2.

[0081] It is also conceivable that the wiring component 10 is transported in a state in which the double-sided adhesive element 50 is not adhered to the target body 80. In this case, it is preferred that the wiring component 10, in a state before the double-sided adhesive element 50 is adhered to the target body 80, furthermore has a release element provided on the outer surface of the double-sided adhesive element 50.
