DOCUMENTS ON THE STATE OF TECHNICAL PATENT DOCUMENTS

[0003] Patent document 1: Published Japanese patent application no. 2018-137208 Outline of the invention; Problem to be solved by the invention

[0004] The cable harness disclosed in patent document 1 can have a compact shape by bending a functional outer element, which is formed into a planar shape, during packaging and transport. For example, wrapping with tape is considered to maintain a bent shape of the cable harness.

[0005] However, if the bending shape of the cable harness is maintained by wrapping it with tape, it is time-consuming to unwrap a section wrapped with tape in order to unfold the cable harness.

[0006] Accordingly, one object of the present invention is to provide a technique for maintaining a bending shape of a wiring element in which a wiring body is bent while the wiring element is easily unfoldable. MEANS TO SOLVENT THE PROBLEM

[0007] To solve the above problem, a wiring element, according to a first aspect, comprises: a wiring body with a wire-shaped transmission element and a base element to which the wire-shaped transmission element is fixed; and a temporary connecting part which, in a state in which the wiring body is bent in an intermediate section in an extension direction of the wire-shaped transmission element, connects sections in which a first part and a second part overlap, extending on opposite sides from a bending point in the wiring body in order to maintain a bending state of the wiring body, and which is configured to be able to break a state of connection between the first part and the second part by a relative separating movement of the first part and the second part.A wiring element according to the first aspect is a wiring element in which the temporary connection part has a direct fixing part formed from the base element in the first part and the base element in the second part, which are directly fixed to one another. A wiring element according to the first aspect comprises a planar element with a main surface on which the wire-shaped transmission element is fixed, as the base element, and a cover that covers the wire-shaped transmission element from a side opposite the planar element, wherein the cover is fixed to the planar element and not to the wire-shaped transmission element, and the temporary connection part connects the cover in at least either the first part or the second part.

[0008] A wiring element according to a second aspect is the wiring element according to the first aspect, in which the temporary connecting part has an adhesive part that lies between the first part and the second part and is bound to the first part and the second part.

[0009] A wiring element according to a third aspect is the wiring element according to the first or second aspect, wherein the temporary connecting part is designed to be able to release the state of connection between the first part and the second part with a force less than a force required to hold the planar element and the wire-shaped transmission element.

[0010] A wiring element according to a fourth aspect is the wiring element according to the first, second or third aspect, in which the temporary connecting part is designed to be able to undo the state of connection of the first part and the second part with less force than a force required to hold the planar element and the cover.

[0011] An arrangement structure of a wiring element according to a fifth aspect comprises: the wiring element according to one of the first, second, third and fourth aspects and an arrangement goal in which the wiring element is positioned in a state in which the state of connection of the first part and the second part by the temporary connection part is lifted and the first part and the second part are unfolded. EFFECTS OF THE INVENTION

[0012] In accordance with each aspect, the temporary connecting element is designed to be able to break the connection between the first and second parts through a relative separation movement of the first and second parts, so that the temporarily connected state established by the temporary connecting element can be dissolved through the unfolding process. Accordingly, the bending shape can be maintained at the wiring element where the wiring body is bent, while unfolding is easily achieved.

[0013] According to a second aspect, the temporary connecting part can be formed simply by the intermediate object, such as an adhesive or double-sided adhesive tape.

[0014] And according to each of these aspects, the other element does not need to be intended as the temporary connecting part.

[0015] According to a third aspect, a detachment of the wire-shaped transmission element from the planar element can be prevented if the state temporarily connected by the temporary connecting part is lifted.

[0016] According to each of the aspects, the temporary connecting part connects the cover to which the wire-shaped transmission element is not fixed, so that a detachment of the wire-shaped transmission element from the planar element can be prevented when the state temporarily connected by the temporary connecting part is lifted.

[0017] According to a fourth aspect, detachment of the cover from the planar element can be prevented if the temporarily connected state through the temporary connecting part is lifted.

[0018] The following describes a wiring element according to an exemplary embodiment. Fig. Figure 1 is a top view showing a wiring element 10 according to the embodiment. Fig. Figure 2 is a cross-sectional view of the wiring element 10, which runs along a line II-II in Fig. 1 is cut off. Fig. Figure 3 is a schematic cross-sectional view of the wiring element 10, which runs along a line III-III in Fig. 2 is cut off. In the Fig. In Figure 1, the wiring element 10 shown on the left of the sheet represents a state before bending a wiring body 12, and on the right of the sheet represents a state after bending the wiring body 12.

[0019] The wiring element 10 comprises a wiring body 12 and a temporary connecting part 40, which maintains a flexed state of the wiring body 12. For example, the wiring element 10 is a packaging form of the wiring body 12.

[0020] The wiring body 12 is an element mounted on a vehicle to supply power to the vehicle's respective equipment or to transmit and receive a signal. The wiring body 12 comprises a wire-shaped transmission element 20 and a base element 30 to which the wire-shaped transmission element 20 is fixed.

[0021] It is sufficient that the wire-shaped transmission element 20 is a wire-shaped element that transmits, for example, electricity or light. For example, the wire-shaped transmission element 20 can be a general wire having a core wire and a cover layer around the core wire, or it can also be a shielded wire, a twisted wire, an enamelled wire, a nichrome wire, a bare wire, or an optical fiber.

[0022] The wire-shaped transmission element 20, which transmits the current, can be various types of signal lines or various types of power lines. The wire-shaped transmission element 20, which transmits the current, can, for example, be used as an antenna or coil that transmits a signal or current to or from a room.

[0023] The wire-shaped transmission element 20 can be a single wire-shaped object or a composite object made of wire-shaped objects (a twisted wire and a cable consisting of wire-shaped objects covered with a sheath).

[0024] For example, a connection and a connector C are provided in a suitable manner according to a connection state of the wire-shaped transmission element 20 and the element on the other side in an end section of the wire-shaped transmission element 20.

[0025] At the in Fig. In the example shown in Figure 3, the wire-shaped transmission element 20 has a transmission wire body 22, which transmits current or light, and a cover layer 24 that covers the transmission wire body 22. If the wire-shaped transmission element 20 is a general wire, the transmission wire body 22 is a core wire, and the cover layer 24 is an insulating cover layer. In the example shown in Figure 3, the transmission wire body 22 is a core wire. Fig. In the 3 illustrated example, the wire-shaped transmission elements 22 with the same diameter and structure are positioned on a planar element 32, however, the diameter and structure of the wire-shaped transmission elements 20 can each be chosen in a suitable way, so that, for example, the wire-shaped transmission elements 20 with different diameters and different structures can be positioned on the same planar element 32.

[0026] The base element 30 is an element that holds the wire-shaped transmission element 20 in a state of two-dimensional support. The base element 30 here comprises the planar element 32 and a cover 34.

[0027] The wire-shaped transmission element 20 is positioned on a major surface of the planar element 32. The planar element 32 holds the wire-shaped transmission elements 20 in a state in which they are arranged side by side. The planar element 32 can be stiff enough to be curved and hold the wire-shaped transmission elements 20 in a two-dimensionally supported state, or it can be stiff enough to maintain a flat state and hold the wire-shaped transmission elements 20 in a two-dimensionally supported state. The planar element 32 can have a three-dimensionally shaped part, such as a part consisting of a wall partially resting on the planar element 32. In the present description, the planar element 32 is a curved element.

[0028] The material forming the planar element 32 is not limited in any particular way; however, the planar element 32 is formed from a material containing, for example, resin made of polyvinyl chloride (PVC), polyethylene terephthalate (PET), or polypropylene (PP). The planar element 32 can be, for example, a fibrous material containing fibers, such as a nonwoven, woven, or knitted fabric, or it can be a non-fibrous material. The non-fibrous material can be a planar material with a uniformly filled internal section or a foam consisting of a foamed resin. The planar element 32 can also contain a material such as metal.

[0029] The planar element 32 can consist of a single layer or several stacked layers. If the planar element 32 consists of stacked layers, it is considered, for example, that a resin layer and a resin layer are stacked together. Likewise, it is considered, for example, that a resin layer and a metal layer are stacked together. The planar element 32 can consist of a non-fiber layer and a non-fiber layer overlapping each other, a non-fiber layer and a fiber layer overlapping each other, or a fiber layer and a fiber layer overlapping each other.

[0030] The wire-shaped transmission element 20 is fixed to the planar element 32. The wire-shaped transmission element 20 is fixed to the planar element 32 in a state where it is positioned along a predetermined path on a main surface of the planar element 32. The planar material 32 is formed into a ribbon-like shape that extends along the path of the wire-shaped transmission element 20. The path of the wire-shaped transmission element 20 on the planar element 32 can be selected appropriately; for example, the wire-shaped transmission element 20 can be positioned straight or curved on the planar element 32. If the wire-shaped transmission element 20 is curved and positioned on the planar element 32, the planar element 32 can also be curved.The wire-shaped transmission elements 20 can branch on the planar element 32 or be positioned so that they cross each other along different paths. In this case, the planar element 32 can also be branched or cross each other.

[0031] At the in Fig. In the example shown, the wire-shaped transmission elements 20 are branched midway and positioned to form an H-shape. The planar element 32 is formed along one of the paths of the wire-shaped transmission elements 20, also forming an H-shape. The planar element 32 is formed to follow the path of the wire-shaped transmission elements 20, thus preventing interference between the planar element 32 and the other component and achieving weight savings. Of course, it is not necessary for the planar element 32 to follow the path of the wire-shaped transmission elements 20; it can also be formed into a different shape, such as a square.

[0032] The wire-shaped transmission element 20 and the planar element 32 are fixed to one another. The above-mentioned fixing state can be either contact area fixing or non-contact area fixing, or both fixing states can be used together. Contact area fixing here means that a section where the wire-shaped transmission element 20 and the planar element 32 are in contact with each other is adhered and fixed. Non-contact area fixing refers to the fixing state that is not contact area fixing.For example, a sewing thread, another flat material, or an adhesive tape presses the wire-shaped transmission element 20 against the flat element 32, or a sewing thread, another flat material, or an adhesive tape surrounds the wire-shaped transmission element 20 and the flat element 32, thereby holding them together. In the following description, the wire-shaped transmission element 20 and the flat element 32 are in a contact-area fixation state. Any description of contact-area fixation is also applicable to non-contact-area fixation, provided that each element and material has a configuration to which non-contact-area fixation is not applicable.

[0033] For the contact area fixation, indirect and direct fixation can be used, or both fixations can be used together in different regions. Indirect fixation means that the wire-shaped transfer element 20 and the flat element 32 adhere and are fixed indirectly via an intermediate element such as an adhesive, a bonding agent, double-sided adhesive tape, or a hook-and-loop fastener. Direct fixation means that the wire-shaped transfer element 20 and the flat element 32 adhere and are fixed directly without an intermediate element, such as an adhesive, which is provided separately.Direct fixing involves melting, for example, resin contained in at least either the wire-shaped transfer element 20 or the flat element 32, causing the wire-shaped transfer element 20 and the flat element 32 to adhere and be fixed. In the following description, the wire-shaped transfer element 20 and the flat element 32 are in a state of direct fixing. Any description relating to direct fixing is also applicable to indirect fixing, provided that each element and material has a configuration to which indirect fixing is applicable.

[0034] To achieve such a direct fixation state, for example, melting the resin with heat or a solvent is considered. That is, the direct fixation state can be either direct fixation by heat or direct fixation by a solvent. Direct fixation by heat is preferred.

[0035] The means used to establish the state of direct fixation are not limited in any particular way; rather, various means can be used, including a known method such as welding, fusion, or fusion joining. For example, if the state of direct fixation is established by heat through welding, various welding methods such as ultrasonic welding, heat pressure welding, hot air welding, and high-frequency welding can be selected. If the state of direct fixation is established by these means, the wire-shaped transmission element 20 and the planar element 32 are in the state of direct fixation by these means. If the state of direct fixation is specifically established, for example, by ultrasonic welding, the wire-shaped transmission element 20 and the planar element 32 are in the state of direct fixation by ultrasonic welding.A section in which the state of direct fixation by heat is produced by welding (a fixing section between the wire-shaped transmission element 20 and the planar element 32) can be called a welded part, and the fixing section formed by ultrasonic welding can, for example, be called an ultrasonic welded part and the fixing section formed by heat pressure welding can be called a heat pressure welded part.

[0036] In the case of direct fixation, it is possible that only the resin contained in the cover layer 24 of the wire-shaped transfer element 20 is melted, or only the resin contained in the planar element 32 is melted. In these cases, the molten resin adheres to an outer surface of the resin on the other side, and in some cases a relatively clear interface may be formed. In the case of direct fixation, both the resin contained in the cover layer 24 of the wire-shaped transfer element 20 and the resin contained in the planar element 32 may be melted. In this case, there may be instances where the two resins are mixed and no clear interface is formed.If, in particular, the cover layer 24 of the wire-shaped transmission element 20 and the planar element 32 have compatible resin, for example, the same resin material, there may be a case in which the two resins are mixed and no clear interface is formed.

[0037] The cover 34 is fixed to the flat element 32. The cover 34 covers the wire-shaped transmission element 20 from a side opposite the flat element 32. The cover 34 is not fixed to the wire-shaped transmission element 20, but can also be fixed to it.

[0038] The fixation state of the fixing of the planar element 32 and the cover 34 is as follows: Fig. The example shown in Figure 3 illustrates indirect fixing using an intermediate object 36, such as an adhesive. It is clear that the fixing state of the planar element 32 and the cover 34 is not limited to indirect fixing; rather, various types of fixing states are available, as described by the fixing state of the planar element 32 and the wire-shaped transfer element 20.

[0039] The same flat element can be used for both the flat element 32 and the cover 34, or different flat elements can be used. Here, different flat elements are used for the flat element 32 and the cover 34. The flat element used for the flat element 32 is better suited for fixing it to the wire-shaped transmission element 20 than the flat element used for the cover 34. The flat element used for the cover 34 has higher stiffness than the flat element used for the flat element 32 and exhibits very good dimensional stability.For example, the planar element 32 is an element with a first layer formed from the same material as the cover 24 of the wire-shaped transmission element 20 to form a solid planar shape and to which an electrical wire is fixed, and a second layer formed from a non-woven fabric and overlapping with the first layer, and the cover 34 is an element formed, for example, from nylon to form a solid planar shape.

[0040] The cover 34, for example, is formed with such rigidity that it is difficult to bend. In this case, it is sufficient for the wiring element 10 to be provided with a bending element that allows for easy bending. The bending elements in the Fig. In the example shown in Figure 2, two lightweight bending parts 16 and 17 are provided. Lightweight bending part 16 is a part on which a section with an accordion structure 35 is provided in the cover 34, featuring alternating raised and recessed areas. Lightweight bending part 17 is a part on which the cover 34 is partially omitted. In particular, lightweight bending part 17 is a part on which the cover 34 is provided at intervals. The wiring body 12 is bent at sections of the lightweight bending parts 16 and 17.

[0041] The temporary connecting element 40 maintains the bent state of the wiring body 12 in a state where the wiring body 12 is bent in the direction of extension within an intermediate section of the wire-shaped transmission element 20. The temporary connecting element 40 joins sections where a first part and a second part, extending alternately on opposite sides from the bend point in the wiring body 12, overlap each other to maintain the bent state of the wiring body 12.

[0042] The temporary connecting element 40 is designed to break the connection between the first and second parts by means of a relative separation movement between them. The direction of this relative separation movement is not specifically limited. For example, a movement in a direction where the first and second parts overlap (downward on the sheet) is also possible. Fig. 2), or a movement in a direction perpendicular to it (in a direction from right to left on the page in Fig. 2 or in a normal direction on the sheet in Fig. 2).

[0043] It is sufficient that the temporary connecting part 40 can temporarily (or provisionally) connect the first part and the second part, and its design is not limited in any particular way. For example, in the case of the Fig. 2 and Fig. In the example shown in Figure 3, an adhesive part 42 is provided as the temporary connecting part 40. The adhesive part 42 can be considered an example of an indirect fixing part.

[0044] The adhesive part 42 has an intermediate object 44 located between the first part and the second part, and bonded to both. The intermediate object 44 can be an adhesive or an adhesive other than the adhesive. Examples of adhesives other than the adhesive include a hot-melt adhesive, a thermosetting adhesive, a moisture-curing adhesive, and a two-liquid adhesive. When using an adhesive other than the adhesive, the first part and the second part cannot be rebonded if they are separated and remain unchanged.

[0045] An alternative indirect fixing element to the adhesive part 42 can be provided as the temporary connecting part 40. For example, a hook and loop fastener can be provided as an alternative indirect fixing element to the adhesive part 42.

[0046] Fig. Figure 4 is a schematic cross-sectional view showing a modified example of the temporary connection part 40. In the case of the Fig. In the example shown in Figure 4, a direct fixing part 46 is provided as the temporary connecting part 40.

[0047] The direct fixing part 46 is formed from a base element 30 in the first part and a base element 30 in the second part, which are directly fixed to each other. In particular, in the case of the Fig. In the example shown in Figure 4, the direct fixing element 46 is formed from the cover 34 in the first part and the cover 34 in the second part, which are directly fixed to one another. The direct fixing here is similar to that described for the fixing state of the planar element 32 and the wire-shaped transmission element 20.

[0048] At the in Fig. In the example shown, temporary connecting parts 40a and 40b maintain a state in which the wiring body 12 is bent into three overlapping parts. Specifically, in the wiring element 10, the wiring body 12 has a base part 13, a first bent part 14, and a second bent part 15. The first bent part 14 is a part that extends from one end section of the base part 13 and is bent so that it overlaps the base part 13. The second bent part 15 is a part that extends from the other end section of the base part 13 and is bent so that it overlaps the first bent part 14. The temporary connecting part 40a then connects the base part 14 and the first bent part 14. The temporary connecting part 40b connects the first bent part 14 and the second bent part 15.Accordingly, in the section relating to the temporary connecting part 40a, the base part 13 and the first bent part 14 function as the first part and the second part, respectively. In the section relating to the temporary connecting part 40b, the first bent part 14 and the second bent part 15 function as the first part and the second part, respectively.

[0049] It is clear that the wiring element 10 does not require the section where the wiring body 12 is bent into three overlapping parts. The wiring element may have one section where the wiring body 12 is bent into two overlapping parts, or it may have one section where the wiring body 12 is bent into four or more overlapping parts. The wiring element may also have only one section where the wiring body 12 is bent into two overlapping parts.

[0050] In the case that the base element 30 comprises the planar element 32 and the cover 34, the temporary connecting part 40 can connect the planar elements 32 to each other, connect the covers 34 to each other, or connect the planar element 32 and the cover 34 to each other. In the case of the Fig. In the example shown, the temporary connecting part 40a connects the covers 34 to each other. The temporary connecting part 40b connects the planar element 32 and the cover 34.

[0051] If several temporary connecting parts 40 are provided, the temporary connecting parts 40 can have the same temporarily connected state or different temporarily connected states. For example, in the Fig. In the example shown, both temporary connecting parts 40a and 40b are the adhesive parts 42, however, one of them can be, for example, the direct fixing part 46.

[0052] If the temporary connecting parts 40 have the same temporarily connected state, the materials from which the temporary connecting parts 40 are formed can be the same or different from each other. Here, in the Fig. In the example shown, the combination of elements connected by temporary connecting part 40a and the combination of elements connected by temporary connecting part 40b are different from each other. In this case, temporary connecting parts 40a and 40b can be made of the same material or of different materials to correspond to the respective material combination.

[0053] It is sufficient that the temporary connecting element 40 is designed to be able to release the connection between the first part and the second part with a force less than that required to hold the planar element 32 and the wire-shaped transmission element 20. Accordingly, separation of the planar element 32 and the wire-shaped transmission element 20 from one another can be prevented when the state temporarily connected by the temporary connecting element 40 is released. In particular, it is sufficient that the temporary connecting element 40b, which temporarily connects the planar element 32, is designed to be able to release the connection between the first part and the second part with a force less than that required to hold the planar element 32 and the wire-shaped transmission element 20.

[0054] The temporary connecting element 40 connects the cover 34 in at least either the first part or the second part. With respect to the temporary connecting element 40a, the temporary connecting element 40 connects the cover 34 in both the base part 13 and the first bent part 14, that is, in both the first part and the second part. With respect to the temporary connecting element 40b, the temporary connecting element 40 connects the cover 34 in the second bent part 15, that is, in one of the first part and the second part. When the temporary connecting element 40 connects the cover 34 in this way, it is sufficient that the temporary connecting element 40 is designed to be able to release the connected state of the first part and the second part with a force less than that required to hold the planar element 32 and the cover 34.Accordingly, separation of the planar element 32 and the cover 34 from each other can be prevented if the state temporarily connected by the temporary connecting part 40 is lifted.

[0055] In the case of the adhesive part 42, for example, the intermediate object 44 is used with low adhesive force, so that the holding force of the temporary connecting part 40 may be reduced. In the case of the direct fixing part 46, the energy supplied during the formation of the direct fixing part 46 is reduced, so that the holding force of the temporary connecting part 40 may be reduced. More specifically, in the case of the direct fixing part 46 formed by ultrasonic welding, the energy supplied during the formation of the direct fixing part 46 can be reduced by reducing the vibration amplitude, welding pressure, and welding time.

[0056] In the case of the direct fixing element 46, for example, even with the same energy supplied during its formation, the holding force can be varied depending on the material combination. With the same energy supplied during the formation of the direct fixing element 46, the holding force between different material types tends to be lower than the holding force between the same material types. It is also applicable that the direct fixing element 46 is selected in the temporary connecting element 40b, which connects the planar element 32 and the cover 34, and the adhesive element 42 is selected in the temporary connecting element 40a, which connects the covers 34 to each other. <entfaltungsvorgang>

[0057] Fig. Figure 5 is an explanatory diagram depicting a state in which the wiring element 10, which has the adhesive part 42, is unfolded. In a Fig. In the example shown in Figure 5, the first part and the second part perform a separation movement in different directions, and the wiring element 10 is unfolded. The same applies to a [missing information - likely a specific example or diagram]. Fig. The example shown in Figure 6 is described below.

[0058] In the event that the wiring element 10, which has the adhesive part 42, is unfolded when the state temporarily connected by the adhesive part 42 is lifted, it is considered that a trace of it enters one of the following conditions or a condition of a combination of several conditions. A first condition is a condition in which an interface between the first part or the second part and the adhesive part 42 is subject to detachment. A second condition is a condition in which one of the first part and the second part adheres partially or completely to the other of the first part and the second part.Typical examples of the second condition include a condition in which an interlayer separation occurs between a section of an inner section of one of the first part and the second part, which forms the interface with the adhesive part 42, and a surrounding section of the same, and part of the interlayer separation in the first part or the second part adheres to the other part of the first part and the second part. A third condition is a condition in which an interlayer separation occurs between a section on one side of the first part and a section on one side of the second part in an inner section of the adhesive part 42. The example in . Fig. 5 represents the third condition.

[0059] In the case of the adhesive part 42 formed by the intermediate object 44, which has re-adherent properties upon clear detachment at an interface with the element on the other side, such as an adhesive, the adhesive part 42 can exhibit re-adherent properties when the wiring element 10, which comprises the adhesive part 42, unfolds and enters the first condition. In the case of the adhesive part 42 formed by the adhesive, a section where the wiring element 10, which comprises the adhesive part 42, unfolds and enters the second or third condition, does not have re-adherent properties or has reduced adhesive properties. For example, a section where the element on the other side does not adhere to a bonding surface of the adhesive part 42 formed by the adhesive, but enters the first condition, can enter a condition with re-adherent properties.However, if dust or dirt adheres to one surface of the element on the opposite side to the bonding surface of the adhesive part 42 formed by the adhesive, the section does not have re-adherent properties or has reduced adhesive properties. For example, a section where an interface between a fibrous material and the adhesive part 42 formed by the adhesive is subject to detachment and the fibrous material adheres to the bonding surface of the adhesive part 42 forms by the adhesive falls under the second condition and does not have re-adherent properties or has reduced adhesive properties.

[0060] In the case of the adhesive part 42 formed by the intermediate object 44, which has no re-adherent properties as long as it is not processed, such as a hot-melting adhesive, or of the adhesive part 42 formed by the intermediate object 44, which also has no re-adherent properties when processed, such as a thermosetting adhesive, the trace of the adhesive part 42 has no re-adherent properties at least when the wiring element 10, which has the adhesive part 42, is unfolded and enters one of the first to third conditions, at least when it remains unchanged.

[0061] Fig. Figure 6 is an explanatory diagram showing a state in which the wiring element 10, which has the direct fixing part 46, is unfolded.

[0062] In the event that the wiring element 10 is unfolded with the direct fixing part 46 when the state temporarily connected by the direct fixing part 46 is lifted, it is considered that a track 50 of the same enters one of the first and second conditions described above. That is, the first condition is a condition in which the interface between the first part and the second part in the direct fixing part 46 is subject to detachment. The first condition can occur if resin of only one of the different material types is melted and the direct fixing part 46 is formed. The second condition is a condition in which one of the first part and the second part is partially or completely adhered to the other of the first part and the second part. The second condition can occur if resin of both different material types is melted and the direct fixing part 46 is formed.Typical examples of the second condition include a condition in which an interlayer separation occurs between a section of an inner section of the first part and the second part, which has the interface of the direct fixing part 46, and a surrounding section of the same, and part of the interlayer separation is deposited on the other part of the first part and the second part. The example in . Fig. 6 represents the second condition.

[0063] In the case that the wiring element 10 is unfolded with the direct fixing part 46, even if the wiring element 10 enters one of the first to third conditions, the track 50 of the direct fixing part 46 has no re-adherent properties at least if it remains unchanged.

[0064] For the temporary connecting part 40, it is preferred that the track of the temporary connecting part 40 has no re-adherent properties when it remains unchanged once the temporarily connected state of the first part and the second part is lifted. <Anordnungsstruktur 100 des Verdrahtungselements>

[0065] Fig. Figure 7 is a schematic cross-sectional view showing an arrangement structure 100 of a wiring element according to an exemplary embodiment.

[0066] The wiring element 10 described above is unfolded and positioned on an arrangement target 80 to form the arrangement structure 100 of the wiring element.

[0067] The design objective 80 is not limited in any particular way. Design objective 80 is any element of a vehicle, such as a roof, a floor, a dashboard, or a reinforcement within a vehicle.

[0068] If the wiring element 10 is to be distinguished from the one after unfolding, the wiring element 10 after unfolding is referred to as wiring element 10A in the following description. In wiring element 10A, a state is released in which the temporary connecting part 40 connects the first part and the second part, and the first part and the second part are unfolded. When the wiring element 10 is unfolded and the temporary connecting part 40 is released, the track 50 of the temporary connecting part 40 remains in the wiring element 10A after unfolding. In the arrangement structure 100 of the wiring element, the track 50 of the temporary connecting part 40 is not used for fixation to the arrangement target 80.

[0069] It is sufficient that reconnection cannot be achieved as long as the track 50 of the temporary connection part 40 in the arrangement structure 100 of the wiring element remains unprocessed and unchanged. Accordingly, it can be prevented that the track 50 of the temporary connection part 40 adheres to a surrounding element after unfolding and interferes with an arrangement process for the wiring element 10. For example, once the temporarily connected state of the first part and the second part is broken, the temporary connection part 40 is selected that has no re-adherent properties when left unchanged. When the wiring element 10, which has this temporary connection part 40, is unfolded, reconnection cannot be achieved as long as the track 50 of the temporary connection part 40 remains unprocessed and unchanged.

[0070] In the wiring element 10, the wiring body 12 is bent such that the bent parts 14 and 15 overlap each other on a surface of the base part 13 on a side opposite a surface which is opposite a side of the arrangement target 80. In the arrangement structure 100 of the wiring element, a track 50a of the temporary connecting part 40a is not located on the side of the arrangement target 80. The temporary connecting part 40b connects the first bent part 14 and the second bent part 15. If the track 50b of the temporary connecting part 40b remains in the first bent part 14, the track 50b of the temporary connecting part 40b is located on the side of the arrangement target 80; however, if the track 50b of the temporary connecting part 40b does not remain in the first bent part 14, the track 50b of the temporary connecting part 40b is not located on the side of the arrangement target 80.If the track 50 of the temporary connecting part 40 is not on the side of the arrangement target 80 after unfolding, it can be prevented that the track 50 of the temporary connecting part 40 adheres to an unintended location in the arrangement target 80 and interferes with an arrangement process for the wiring element 10.

[0071] In the wiring element 10 with the above configuration, the temporary connecting part 40 is designed to be able to release the connection between the first and second parts by means of a relative separation movement of the first and second parts, so that the temporarily connected state established by the temporary connecting part 40 can be released by the unfolding process. Accordingly, the bending shape of the wiring element 10 can be maintained, and unfolding can be easily achieved.

[0072] If the temporary connecting part 40 has the adhesive part 42, the temporary connecting part 40 can be easily formed by the intermediate object 44, such as an adhesive or double-sided adhesive tape. If the temporary connecting part 40 has the direct fixing part 46, the other element does not need to be designated as the temporary connecting part 40.

[0073] The temporary connecting part 40 is designed to be able to release the state of connection between the first part and the second part with a force less than that required to hold the planar element 32 and the wire-shaped transmission element 20, so that a separation of the wire-shaped transmission element 20 from the planar element 32 can be prevented when the state temporarily connected by the temporary connecting part 40 is released.

[0074] The temporary connecting part 40 connects the cover 34, to which the wire-shaped transmission element 20 is not fixed. Accordingly, detachment of the wire-shaped transmission element 20 from the planar element 32 can be prevented when the temporarily connected state established by the temporary connecting part 40 is released.

[0075] The temporary connecting part 40 is designed to be able to release the state of connection between the first part and the second part with a force less than that required to hold the planar element 32 and the cover 34, so that separation of the cover 34 from the planar element 32 can be prevented when the state temporarily connected by the temporary connecting part 40 is released. Variation example, which is not claimed

[0076] Fig. Figure 8 is a schematic cross-sectional view that represents a modification example for the wiring element 10.

[0077] In the description above, the base element 30 in the wiring element 10 has the cover 34; however, this configuration is not necessary. There may be a case in which the base element 130 does not have the cover 34, as in a Fig. 8 shown wiring element 110. In this case, the temporary connecting part 40d connects the planar elements 32 to each other.

[0078] In the description above, the temporary connecting part 40 connects the portion of the base element 30 that overlaps with the wire-shaped transmission element 20; however, this configuration is not necessary. The temporary connecting part 40d can connect a portion that does not overlap with the wire-shaped transmission element 20 (a lateral section of the wire-shaped transmission element 20), as in the one shown in Fig. 8 examples shown.

[0079] At the in Fig. In the example shown in Figure 8, a wiring body 112 is bent such that the wire-shaped transmission elements 20 face each other. Alternatively, the wiring body 112 can be bent such that surfaces of the planar element 32, to which the wire-shaped transmission elements 20 are attached, face each other; however, this configuration is not necessary. The wiring body can be bent such that surfaces of the planar element 32, to which the wire-shaped transmission element 20 is attached, face each other. The wiring body can also be bent such that a surface of the planar element 32, to which the wire-shaped transmission element 20 is attached, faces each other, as does a surface of the same element, to which the wire-shaped transmission element 20 is not attached.

[0080] Furthermore, in the description above, the wire-like transmission element 20 is fixed to the flat element 32 as the base element 30 in the wiring body 12; however, this configuration is not necessary. For example, a wire-like conductor can be fixed to an inner section of the base element in the wiring body. A so-called flexible flat cable (FFC) can be used as the wiring body, which is formed, for example, by placing wire-like conductors between two films or by extruding a resin material around wire-like conductors.

[0081] Each embodiment and each variation described in the exemplary embodiment can be combined in a suitable manner, as long as they do not contradict each other.

[0082] Although the present invention is described in detail, the preceding description is in all aspects illustrative and does not limit the invention. It is therefore understood that numerous modifications and variants can be developed without departing from the scope of the invention.
