[0008] First, embodiments of the present disclosure are listed and described.

[0009] A wiring component according to the present disclosure is designed as follows.

[0010] (1) A wiring component comprises: at least one wire-shaped transmission element; a fixing flat part with a first main surface to which the at least one wire-shaped transmission element is fixed; at least one intermediate flat part which is fixed to the fixing flat part and has a first contact surface; and a double-sided adhesive element which is attached to the first contact surface, wherein, if a surface of the fixing flat part which is in contact with the intermediate flat part is a second contact surface, an adhesive force between the first contact surface and the double-sided adhesive element is greater than an adhesive force between the second contact surface and the double-sided adhesive element.When the wiring component is attached and fixed to the adhesive target body by means of the double-sided adhesive element, the double-sided adhesive element is accordingly arranged on the intermediate flat part, which results in a higher strength of the fixation than in a case where the double-sided adhesive element is arranged on the fixing flat part.

[0011] (2) The intermediate flat part may be fixed to another main surface of the fixing flat part, which is located on one side opposite the main surface of the fixing flat part to which the at least one wire-shaped transfer element is fixed. Accordingly, the other main surface of the fixing flat part is firmly fixed to the adhesive target body via the double-sided adhesive element and the intermediate flat part.

[0012] (3) The first contact surface can also be a surface of a plastic layer with a uniformly filled cross-section, and the second contact surface can be a surface of a fibrous material layer. The effective contact area of ​​the first contact surface with the double-sided adhesive element is larger than the effective contact area of ​​the second contact surface with the double-sided adhesive element. Accordingly, a simple embodiment is achieved in which the adhesive force between the first contact surface and the double-sided adhesive element is greater than the adhesive force between the second contact surface and the double-sided adhesive element.

[0013] (4) The fixing flat part may have a first layer and a second layer stacked on top of each other. The first layer may be a fixing layer that secures the at least one wire-shaped transfer element. The second layer may be the fiber material layer, and the intermediate flat part may be fixed to the second layer. A necessary function, other than fixing the at least one wire-shaped transfer element to the fixing flat part, may be added to the second layer. In this case, too, the intermediate flat part is fixed to the second layer, thus allowing one side of the second layer of the fixing flat part to be fixed to the adhesive target body.

[0014] (5) The intermediate flat part and the fixing flat part may be welded together. Accordingly, the intermediate flat part and the fixing flat part are firmly fixed to each other.

[0015] (6) The intermediate flat part can be arranged along a longitudinal direction of a section of the fixing flat part. This counteracts any increase in the weight of the wiring component caused by the provision of the intermediate flat part.

[0016] (7) Several intermediate flat parts may also be provided, and the multiple intermediate flat parts may comprise several flat section segments arranged at intervals along a longitudinal direction of the fixing flat part. Accordingly, the fixing flat part can be fixed to the adhesive target body at several positions along its longitudinal direction, thus counteracting any increase in the weight of the wiring component caused by the provision of the intermediate flat part.

[0017] (8) Several wire-shaped transmission elements may also be provided, a branching section may be arranged on the fixing flat part in which some wire-shaped transmission elements of the several wire-shaped transmission elements branch off from other wire-shaped transmission elements, and the intermediate flat part may have a section that covers the branching section. Accordingly, the branching section may be fixed to the adhesive target body.

[0018] (9) The intermediate flat part may have a higher stiffness than the fixing flat part. Accordingly, a shape of the wiring component is held by the intermediate flat part. DETAILS OF EXAMPLES OF EXECUTION

[0019] 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

[0020] 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.

[0021] The wiring component 10 comprises a wiring body 12, an intermediate flat part 40, and 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.

[0022] 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.

[0023] 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.

[0024] 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 example, several wire-shaped transmission elements 20 branch out on the fixing flat 30. A section where 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. In this example, there are two branching sections DP1 and DP2 on the fixing flat 30.

[0025] 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.

[0026] 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.

[0027] 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).

[0028] The respective wire-shaped transmission element 20 is fixed to a main surface of the fixing flat part 30. A fixing structure by which the respective wire-shaped transmission element 20 is fixed to the fixing flat part 30 is not specifically limited, 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, 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”.

[0029] 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.

[0030] 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.

[0031] 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.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.

[0032] 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.

[0033] The fixing flat part 30 can have a single-layer structure. If the fixing flat part 30 has a single-layer structure, the layer is a fixing layer to which the at least one wire-shaped transmission element is fixed, and a layer to which the intermediate flat part is fixed. 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 be a flat part made of metal.

[0034] The fixing flat part 30 can also have a multilayer structure. If the fixing flat part has the multilayer structure, various types of layers described in connection with the single-layer structure described above can be used for the layer that forms the fixing layer. For the layer that does not form the fixing layer, various types of layers described in connection with the single-layer structure described above can be used, as well as a layer that is not suitable for fixing the at least one wire-shaped transmission element.

[0035] In this case, the fixing flat part 30 has a first layer 31 and a second layer 32 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 31 and the second layer 32. 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 31 and the second layer 32.

[0036] The first layer 31 is a fixing layer. The layer used as the first layer 31 is not specifically restricted, but can be any layer as long as it can fix the respective wire-shaped transmission element to the fixing flat part. For example, the first layer 31 can also be a uniformly plastic-filled plastic layer with a uniformly filled cross-section. The wire-shaped transmission elements 20 are fixed by the first layer 31. The plastic material of the first layer 31 is, for example, the same as that of the sheathing layer 24. A surface of the first layer 31 is a major surface of the fixing flat part 30.

[0037] The second layer 32 is a layer of fiber material. The intermediate flat part 40 is fixed to the second layer 32. One surface of the second layer 32 is the other main surface of the fixing flat part 30.

[0038] The first layer 31 and the second layer 32 are fixed to one another, with the other surface of the first layer 31 and the other surface of the second layer 32 being in contact with each other. The fixation state in which the first layer 31 and the second layer 32 are fixed to one another is not specifically restricted; however, fixation by welding or bonding is preferred. Specifically, the first layer 31, which is a plastic layer, and the second layer 32, 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 31 and the second layer 32 to one another. In the present case, the first layer 31 and the second layer 32 are welded together.This means that the plastic of the first layer 31, which is a plastic layer, penetrates the interfiber space of the second layer 32, which is a fiber material layer, in its 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 31 and the second layer 32 are fixed to one another. The first layer 31 and the second layer 32 are of the same size. One layer of the first layer 31 and the second layer 32 can also be larger than the other. The first layer 31 and the second layer 32 are fixed to one another over the entire area where they are in contact. The first layer 31 and the second layer 32 can also be fixed to one another only in a portion of the area where they are in contact.

[0039] The fixing flat part 30 can be a flexible element. For example, the first layer 31 is a plastic layer with a uniformly filled cross-section made of a flexible plastic such as soft PVC, the second layer 32 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).

[0040] 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.

[0041] The intermediate flat part 40 covers the wiring body 12. The intermediate flat part 40 covers the other main surface of the fixing flat part 30. The intermediate flat part 40 is fixed to the fixing flat part 30. The intermediate flat part 40 is fixed to a section of the fixing flat part 30 that is offset from (spaced a predetermined distance from) a section to which the wire-shaped transmission elements 20 are fixed. In the present example, the intermediate flat part 40 is fixed to the other main surface of the fixing flat part 30.

[0042] The intermediate flat part 40 can completely or partially overlap the fixing flat part 30. The intermediate flat part 40 can be made of the same material as the fixing flat part 30 or of a different material. The intermediate flat part 40 can be a flat part made of plastic. For example, the intermediate flat part 40 can be made of a plastic such as PVC, PE, PP, or PET, in the same way as the fixing flat part 30.

[0043] A flat part consisting of the fixing flat part 30 and the intermediate flat part 40 can have a higher stiffness than the other of the two. In this case, the intermediate flat part 40 is designed with a higher stiffness than the fixing flat part 30. For example, the intermediate 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 intermediate flat part 40 can prevent bending of the cable body 12. In this case, it is described that the intermediate 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 intermediate flat part 40 can also have a multi-layer structure.

[0044] The intermediate flat part 40 and the fixing flat part 30 are fixed to one another, with a surface of the plastic layer of the intermediate flat part 40 and a surface of the fiber material layer of the fixing flat part 30 in contact with each other. The fixing state of the intermediate flat part 40 and the fixing flat part 30 is not specifically restricted; however, fixing by welding or gluing is preferred. The intermediate flat part 40 and the fixing flat part 30 are welded together. The following three states are examples of fixing the intermediate flat part 40 and the fixing flat part 30 by welding.The intermediate flat part 40 and the fixing flat part 30 can be welded together in any one of the following three states, and it is preferred that the intermediate flat part 40 and / or the fixing flat part 30 be melted so that the intermediate flat part 40 and the fixing flat part 30 can be fixed together.

[0045] The first state is as follows: In the case of the plastic layer of the intermediate flat part 40 and the fiber material layer of the fixing flat part 30, the plastic of the plastic layer of the intermediate flat part 40 is heated and melted, for example by ultrasonic welding, so that it comes into contact with the fixing flat part 30 and adheres to it, thus welding the intermediate flat part 40 and the fixing flat part 30 together. In this process, the plastic of the plastic layer in the cover flat part 40 can either only be in contact with the surface of the fiber material layer or it can also penetrate the fiber material layer. If the plastic of the plastic layer in the intermediate flat part 40 penetrates the fiber space of the fiber material layer and is fixed to it, this configuration creates the so-called anchoring effect, thus firmly fixing the intermediate flat part 40 and the fixing flat part 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 intermediate flat part 40 penetrates the interfiber space of the fiber material layer in the fixing flat part 30, and the intermediate flat part 40 and the fixing flat part 30 are fixed to one another.

[0046] 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 intermediate flat part 40 and adheres to it, thereby welding the intermediate flat part 40 and the fixing flat part 30 together.

[0047] The third state is as follows: The plastic forming the intermediate flat part 40 is melted and penetrates the fiber material layer in the fixing flat part 30. The plastic of the fixing layer in the fixing flat part 30 is also melted and penetrates the fiber material layer. The plastic of the intermediate flat part 40 in the fiber material layer and the plastic of the fixing flat part 30 then come into contact with each other and adhere to one another, thus welding the intermediate flat part 40 and the fixing flat part 30 together. In this third embodiment, the plastic forming the intermediate flat part 40 penetrates the fiber material layer in the fixing flat part 30; this configuration thus creates the so-called anchoring effect and the firm fixation of the intermediate flat part 30 and the fixing flat part 40.

[0048] When the intermediate flat part 40 and the fixing flat part 30 are fixed together by adhesive bonding, an adhesive is in contact with and adheres to both parts. The adhesive can either adhere only to the surface of the fiber material layer or penetrate the fiber material layer. If the adhesive penetrates the fiber material layer, this creates the so-called anchoring effect. Accordingly, the intermediate flat part 40 and the fixing flat part 30 are firmly fixed together by the adhesive.

[0049] The intermediate flat section 40 is provided in sections along a longitudinal direction of the fixing flat section 30. The intermediate flat section 40 comprises several flat section segments 41, 42, 43, and 44. Each of the flat section segments 41, 42, 43, and 44 covers only a partial section of the fixing flat section 30 along the longitudinal direction. The flat section segments 41, 42, 43, and 44 are provided at intervals along the longitudinal direction of the fixing flat section 30. The intermediate flat section 40 has a section that covers the branching sections DP1 and DP2. In this case, the flat section segments 42 and 43 cover the branching sections DP1 and DP2, respectively.

[0050] 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 section 41 is located at an end section of the fixing flat section 30. Flat sections 42 and 43 are central sections of the fixing flat section 30 and are located in branch sections DP1 and DP2. 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.

[0051] In the present example, the flat section 41 is provided at all of the several (in this case, five) end sections of the fixing flat section 30. The flat section 431 does not need to be provided at all of the several end sections of the fixing flat section 30. A given flat section 41 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 41 is provided at the end section of the fixing flat section 30 means that an end edge of the flat section 41 and an end edge of the fixing flat section 30 are at most 20 mm apart in a longitudinal direction.

[0052] The flat section 41 is welded to the fixing flat section 30 laterally, for example, to the wire-shaped transmission elements 20. The flat section 41 and the fixing flat section 30 are welded together at two positions. Two welding positions WP1, at which the flat section 41 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 WP1, at which the flat section 41 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.

[0053] The flat section 42 is provided in the branching section DP1. Branching section DP1 is a section in which the several wire-shaped transmission elements 20 branch into three sections. Three branch lines extend from a branching point in branching section DP1. 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 DP1. 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.

[0054] The flat section 42 is, for example, welded laterally to the wire-shaped transmission elements 20 and the fixing flat section 30. The flat section 42 and the fixing flat section 30 are welded together at three positions. The three welding positions WP2 and WP3, where the flat section 42 and the fixing flat section 30 are welded together, are located at positions surrounding the branching section DP1. As shown 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.

[0055] The flat section 43 is provided in the branching section DP2. Branching section DP2 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 DP2. Among the four branch lines, there are pairs of branch lines that are continuously connected to each other via the branching point, perpendicular to each other. The angle between the two branch lines continuously connected via the branching point need not be a right angle.

[0056] A position where the flat section 43 is welded to the fixing flat section 30 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. The flat section 43 is welded to the fixing flat section 30 at four corner positions. The four welding positions WP4, where the flat section 43 and the fixing flat section 30 are welded together, are located at positions surrounding the branch section DP2.

[0057] 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 41.

[0058] A double-sided adhesive element 50 is attached to the intermediate flat part 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 intermediate flat part 40 and also in a section opposite it. The double-sided adhesive element 50 adheres to an outer surface of the cover flat part 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.

[0059] 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 intermediate flat section 40 is a large flat section, such as the fixing flat section 30, then the double-sided adhesive element 50 is preferably provided in a section of the intermediate flat section 40.

[0060] A surface of the intermediate flat part 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 flat part 30 that is in contact with the intermediate flat part 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).

[0061] 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 intermediate 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 intermediate 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.

[0062] As described above, the intermediate flat part 40 has a single-layer structure formed by the plastic layer with a uniformly filled cross-section. The cover flat part 40 is fixed to the second layer 32, which is the fiber material layer in the fixing flat part 30, which has a double-layer structure formed by the first layer 31 and the second layer 32. 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.

[0063] 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.

[0064] Fig. Figure 7 is an explanatory diagram illustrating the wiring component 10 that is attached to the adhesive target body 80.

[0065] In this case, the intermediate flat part 40 has a higher stiffness than the fixing flat part 30. Thus, in a section where the intermediate flat part 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 shown in Fig. Figure 7 illustrates the process, showing the intermediate flat part 40 held in a flat form in the section where it is provided. As a result, the double-sided adhesive element 50 can be easily attached to the adhesive target body 80.

[0066] According to the wiring component 10 with the above configuration, the double-sided adhesive element 50 is provided on the intermediate flat part 40. Accordingly, the strength of the fixation is higher in a case where the wiring component 10 is attached and fixed to the adhesive target body 80 by the double-sided adhesive element 50 than in a case where the double-sided adhesive element 50 is provided directly on the fixing flat part 30.

[0067] The first contact surface CS1 is a surface of the plastic layer with a uniformly filled cross-section, and the second contact surface CS2 is a surface of the fiber material layer. Therefore, the effective contact area of ​​the first contact surface CS1 with the double-sided adhesive element 50 is larger than the effective contact area of ​​the second contact surface CS2 with the double-sided adhesive element 50. Accordingly, a design is easily achieved 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.

[0068] Furthermore, a situation may arise where the double-sided adhesive element 50 is detached during maintenance of the wiring component 10 or during reattachment to the adhesive target body 80. If the double-sided adhesive element 50 is provided on the fiber material layer, there is a possibility that part of the fiber material layer will be damaged when the double-sided adhesive element 50 is detached from it. In contrast, in this case, the double-sided adhesive element 50 is provided on the plastic layer with a uniformly filled cross-section; thus, the double-sided adhesive element 50 is easily and cleanly detached when removed from the plastic layer with a uniformly filled cross-section, and the plastic layer is hardly damaged.Accordingly, the fixing flat part 30 and the intermediate flat part 40 can be reused unchanged even if the double-sided adhesive element 50 is detached from the wiring component 10.

[0069] The fixing flat part 30 has a second layer 32 as a fiber material layer; a necessary function, different from fixing the wire-shaped transmission element 20 to the fixing flat part 30, can be added to the second layer 32. In this case as well, the intermediate flat part 40 is fixed to the second layer 32, thus one side of the second layer 32 of the fixing flat part 30 can be fixed to the adhesive target body 80.

[0070] The intermediate flat part 40 and the fixing flat part 30 are welded together and thus firmly fixed to each other.

[0071] The intermediate flat section 40 is provided section by section along the longitudinal direction of the fixing flat section 30, thus counteracting any increase in the weight of the wiring component 10 caused by the provision of the intermediate flat section 40. The intermediate flat section 40 comprises the several flat section segments 41, 42, 43, and 44, which are provided at intervals along the longitudinal direction of the fixing flat section 30. Accordingly, the fixing flat section 30 can be fixed to the adhesive target body 80 at several positions along its longitudinal direction, thus counteracting any increase in the weight of the wiring component 10 caused by the provision of the intermediate flat section 40. The intermediate flat section 40 has a section that covers the branching section DP, so that the branching section DP can be fixed to the adhesive target body 80.

[0072] The intermediate flat part 40 has a higher stiffness than the fixing flat part 30; thus, the shape of the wiring component 10 is maintained by the intermediate flat part 40. Accordingly, the section of the wiring component 10 to which the intermediate flat part 40 is fixed is easily kept flat. Similarly, 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. Variation example

[0073] Fig. Figure 8 is a rear view illustrating a modified example of the wiring component 10.

[0074] The shapes of a fixing flat part 130 and a flat part section 143 in the branching section DP2 are shown in the Fig. 8 illustrated cabling component 110 differently.

[0075] The number of branches of the fixing flat part 130 in branching section DP2 is less than the number of branches of the wire-shaped transmission element 20. The multiple wire-shaped transmission elements 20 are branched into four sections, and the fixing flat part 130 is branched into three sections. In one direction of one of the branch lines, the fixing flat part 130 is not elongated. This branch line extends from a lateral edge of the fixing flat part 130. It is also possible that the fixing flat part 130 does not branch in branching sections DP1 and DP2.

[0076] The flat section 143 branches in the same direction as the fixing flat section 130. In this case, the flat section 143 branches into three sections. The flat section 143 is formed in the shape of a concave octagon with two re-entrant angles. The flat section 42, like the flat section 143 in branching section DP1, can be formed in a shape that branches into three sections. If the fixing flat section 130, like the fixing flat section 30 in branching section DP2, branches into four sections, the flat section 43 can be formed in a shape that branches into four sections.

[0077] The flat section 143 and the fixing flat section 130 are welded together at four positions. Two welding positions WP5, selected from the four welding positions WP5 and WP6, are located on sections that each have a re-entrant angle in the flat section 143. Each of the welding positions WP5 is positioned to run along two sides that form the re-entrant angle. Each of the welding positions WP5 is L-shaped. The remaining two welding positions WP6, selected from the four welding positions WP5 and WP6, are elongated on one side. Welding positions WP5 and WP6 are each located in an area larger than welding position WP4. Accordingly, the strength of the connection between the flat section 143 and the fixing flat section 130 is increased.

[0078] The double-sided adhesive element 50 can be provided along the entire flat section 143. 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.

[0079] Fig. Figure 9 is a schematic cross-sectional view illustrating a modification example for the cabling component 10.

[0080] In the Fig. In Figure 9, the wiring component 210 is provided by an intermediate flat part 240 on one side of a main surface of a fixing flat part 230. The wiring component 210 is attached to the adhesive target body 80, with a main surface of the fixing flat part 230, to which the wire-shaped transmission element 20 is fixed, facing the adhesive target body 80. In this case, a main surface of the fixing flat part 230 can be a surface of a plastic material layer such as a nonwoven fabric.

[0081] 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.

[0082] The description of the exemplary embodiment provides several flat sections 41, 42, 43, and 44, but this is not mandatory. The flat sections 41, 42, 43, and 44 can be omitted or added as needed. It is sufficient that at least one of the flat sections 41, 42, 43, and 44 is provided.

[0083] In the description of the exemplary embodiment, the intermediate flat part 40 has a higher stiffness than the fixing flat part 30; however, this is not mandatory. The intermediate flat part 40 can have the same or a lower stiffness than the fixing flat part 30. The intermediate flat part 40 can, for example, be a film.

[0084] 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.

[0085] A uniformly filled cross-section can also be understood as a shape in which, for example, at least the surface of the first contact area has minor gaps. The condition in which this surface has minor gaps means that the gaps formed in the surface of the first contact area are smaller than those in the second contact area.

[0086] All embodiments described in the exemplary embodiment and the examples of modifications can be freely combined, as long as they are not incompatible with each other.
