Summary of the Invention
Problems to be Solved by the Invention
[0004] When providing a cover that covers a wiring member having a linear transmission member and a sheet, it is desired to reduce the size of the sheet while suppressing a decrease in the fixing strength of the cover.
[0005] Therefore, an object is to provide a technique capable of reducing the size of the sheet while suppressing a decrease in the fixing strength of the cover.
Means for Solving the Problems
[0006] The adherent with a wiring member of the present disclosure includes a wiring member including a sheet and a linear transmission member fixed to the sheet, an adherent provided at a position in a vehicle where the wiring member is disposed and fixed to the sheet via a first fixing member, and a cover that covers the linear transmission member from a side opposite to the sheet, and the cover is an adherent with a wiring member that is fixed to the adherent via a second fixing member at least on one side of the wiring member.
Effects of the Invention
[0007] According to this disclosure, the sheet can be made smaller while suppressing a decrease in the fixing strength of the cover. [Brief explanation of the drawing]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.
[0010] The adherend with wiring components described herein is as follows:
[0011] (1) A wiring member comprising a sheet, a wiring member including a linear transmission member fixed to the sheet, a substrate provided in a vehicle at a position where the wiring member is arranged and fixed to the sheet via a first fixing member, and a cover covering the linear transmission member from the opposite side of the sheet, wherein the cover is fixed to the substrate via a second fixing member on at least one side of the wiring member. By fixing the cover to the substrate, it becomes easier to secure the necessary fixing strength of the cover, and it becomes possible to omit or reduce the area on the sheet for fixing the cover. This makes it possible to reduce the size of the sheet while suppressing a decrease in the fixing strength of the cover.
[0012] (2) In the adherend with wiring member of (1), the dimensions of the area in the width direction of the sheet where the cover and the adherend are fixed via the second fixing member may be larger than the dimensions of the side edge area of the sheet where the linear transmission member is not arranged. As a result, the area of the cover having dimensions larger than the side edge area of the sheet is fixed to the adherend.
[0013] (3) In the adherend with the wiring member according to (1) or (2), the cover may be fixed in a state where it is in contact with the linear transmission member and stretched along the width direction of the sheet. This allows the cover to press the wiring member toward the adherend.
[0014] (4) In any one of the wiring members attached to a substrate according to (1) to (3), the cover and the sheet may be separate components, and the cover may be fixed to the substrate on both sides of the wiring member. This makes it easy to use a material with different physical properties from the sheet as the cover.
[0015] (5) In any one of the adherents with a wiring member according to (1) to (3), the cover may be provided by folding back a part of the base material constituting the sheet, and the cover may be fixed to the adherent only on one side of the wiring member. Thereby, on one side, it is not necessary to fix the cover and the adherent, so that the fixing work of the cover and the adherent becomes easy.
[0016] (6) In any one of the adherents with a wiring member according to (1) to (5), both the first fixing member and the second fixing member may be adhesive members. Thereby, the wiring member, the adherent, and the cover can be easily fixed via the adhesive member.
[0017] (7) In the adherent with a wiring member according to (6), the cover has a sheet adhesion part that overlaps with the side edge part of the sheet and is adhered to the side edge part of the sheet via the adhesive member, and a part that protrudes outward from the side edge part of the sheet along the width direction of the sheet from the sheet adhesion part and is adhered to the adherent via the adhesive member. Thereby, the cover can be fixed to both the adherent and the sheet.
[0018] (8) Further, the wiring member with a cover of the present disclosure includes a sheet, a wiring member including a linear transmission member fixed to the sheet, and a cover that covers the wiring member. The cover has, at least on one side of the wiring member, a sheet adhesion part that overlaps with the side edge part of the sheet and is adhered to the side edge part of the sheet via the adhesive member, and a protruding part that protrudes outward from the side edge part of the sheet along the width direction of the sheet from the sheet adhesion part. It is a wiring member with a cover. By providing the sheet adhesion part, the cover can be temporarily held on the wiring member. Further, by providing the protruding part, the protruding part and the adherent can be fixed. In addition to the sheet adhesion part of the cover being fixed to the sheet, the protruding part is fixed to the adherent, thereby suppressing a decrease in the fixing strength of the cover while reducing the size of the sheet.
[0019] [Details of Embodiments of the Present Disclosure] Specific examples of the adherent with a wiring member of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0020] [Embodiment 1] Hereinafter, the adherent with a wiring member according to Embodiment 1 will be described. FIG. 1 is a plan view showing the adherent with a wiring member 10 according to Embodiment 1. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is an explanatory view showing a state of manufacturing the adherent with a wiring member 10.
[0021] The adherent with a wiring member 10 includes a wiring member 20, an adherent 40, and a cover 50. The wiring member 20 and the cover 50 are fixed to the adherent 40. The wiring member 20 is fixed to the adherent 40 via a first fixing member. The cover 50 is fixed to the adherent 40 via a second fixing member. In this example, both the first fixing member and the second fixing member are adhesive members 60. The cover 50 is fixed to the adherent 40 at least on one side of the wiring member 20. In this example, the cover 50 and the sheet 22 are separate members, and the cover 50 is fixed to the adherent 40 on both sides of the wiring member 20.
[0022] The wiring member 20 includes a sheet 22 and a linear transmission member 26. The linear transmission member 26 is fixed to the sheet 22. A plurality of linear transmission members 26 are arranged side by side on the first surface of the sheet 22. Each of the plurality of linear transmission members 26 is fixed to the sheet 22. The plurality of linear transmission members 26 are held in a state of being arranged side by side on the first surface of the sheet 22. Thereby, the wiring member 20 has a reduced height dimension with respect to the dimensions in the width direction and the length direction, and is flat.
[0023] The sheet 22 only needs to be capable of fixing the linear transmission member 26, and its material, structure, etc., are not particularly limited. Regarding the material constituting the sheet 22, here the sheet 22 is formed of a resin material. The material constituting the sheet 22 may be a material other than resin, such as metal or inorganic material. Regarding the structure of the sheet 22, here the sheet 22 has a two-layer structure. The structure of the sheet 22 may be a single-layer structure or a multi-layer structure of three or more layers.
[0024] The sheet 22 includes a first layer 23 and a second layer 24. The first layer 23 is a fusion layer 23. A linear transmission member 26 is fused and fixed to the fusion layer 23. The fusion layer 23 contains a resin material, preferably a thermoplastic resin material. The resin material of the fusion layer 23 softens and fuses to the fusion mating material. The type of resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc., can be used.
[0025] The structure of the fusion layer 23 is not particularly limited. For example, the fusion layer 23 may be a sheet having a uniform solid cross-section (also called a non-foamed sheet or solid sheet). Alternatively, the fusion layer 23 may be a foamed sheet or the like. Alternatively, the fusion layer 23 may be a fibrous sheet such as a knitted fabric, woven fabric, or nonwoven fabric. One surface of the first layer 23 becomes the first surface of the sheet 22.
[0026] The second layer 24 may be made of a different material or have a different structure than the fusion layer 23. The second layer 24 may enhance the functions of the fusion layer 23 or add functions to the sheet 22 that are not present in the fusion layer 23. The material constituting the second layer 24 may be a metal, an inorganic material, or the like, in addition to the materials described for the fusion layer 23. The structure of the second layer 24 may be any of the structures described for the fusion layer 23. One surface of the second layer 24 becomes the second surface of the sheet 22.
[0027] The first layer 23 and the second layer 24 are fixed together while the other surface of the first layer 23 and the other surface of the second layer 24 are in contact. The manner in which the first layer 23 and the second layer 24 are fixed together is not particularly limited, but it is preferable that they be fixed by fusion or adhesive. For example, if at least one of the first layer 23 and the second layer 24 is a sheet with voids on its surface, such as a fibrous sheet or a foamed sheet, then a resin material or adhesive can be inserted into the voids and fixed together. This produces a so-called anchoring effect, firmly fixing the first layer 23 and the second layer 24 together.
[0028] Here, the first layer 23 is described as a solid sheet made of resin, and the second layer 24 is described as a fibrous sheet. Here, the first layer 23 and the second layer 24 are described as being fused together. That is, the resin of the first layer 23 enters between the fibers of the second layer 24 while in a fluid state, and then hardens. As a result, the state in which the resin of the first layer 23 enters between the fibers of the second layer 24 is maintained, and the first layer 23 and the second layer 24 are firmly fixed together.
[0029] The first layer 23 and the second layer 24 are formed to be the same size (same planar shape). One of the first layer 23 and the second layer 24 may be formed to be larger than the other. The entire contact area of the first layer 23 and the second layer 24 is fixed. Only a portion of the contact area of the first layer 23 and the second layer 24 may be fixed.
[0030] The sheet 22 may be made of a soft material. For example, the sheet 22 may be made of a soft material, such as a solid sheet made of a soft resin such as soft PVC for the first layer 23 and a nonwoven fabric made of PET for the second layer 24. For example, the sheet 22 may have the flexibility to follow the bending of the linear transmission member 26. The wiring member 20 may be made capable of bending in the thickness direction (bending so that the folds follow the main surface of the sheet 22).
[0031] The linear transmission member 26 is a linear member that transmits electricity or light, etc. One or more linear transmission members 26 are provided. The linear transmission member 26 is assumed to be a member that connects parts to each other in a vehicle. For example, a connector is provided at the end of the linear transmission member 26. The linear transmission member 26 is connected to the other part by connecting this connector to a connector provided on the other part. In other words, the wiring member 20 is used as a wiring member 20 that electrically (or optically) connects various parts to each other in a vehicle, etc. The connector may be fixed to the sheet 22. The connector may be provided on the outside of the sheet 22.
[0032] The path of the linear transmission member 26 is set according to the position of the component to which it will be connected. By fixing the linear transmission member 26 to the sheet 22, the linear transmission member 26 is kept in a state that follows the wiring path according to the position of the component to which it will be connected. Here, the linear transmission member 26 extends in a straight line on the sheet 22. The sheet 22 is formed in a shape (in this case, a straight line) according to the path of the linear transmission member 26. However, the path of the linear transmission member 26 may be composed of a combination of straight and curved paths. The sheet 22 may also be composed of a combination of straight and curved paths. Multiple linear transmission members 26 may be fixed to the sheet 22 in a manner in which branch lines branch off from a main line. The sheet 22 may also be formed in a shape in which the part where the main line is fixed branches off from the part where the branch lines are fixed.
[0033] The linear transmission member 26 includes a transmission line body 27 and a coating layer 28. The transmission line body 27 is a transmission path for transmitting electricity or light. For example, if the linear transmission member 26 is an electric wire, the transmission line body 27 is a conductor core wire. The conductor core wire is composed of one or more strands. The strands are formed from materials such as copper, copper alloy, aluminum, aluminum alloy, etc. Also, for example, if the linear transmission member 26 is an optical fiber, the transmission line body 27 is a core and cladding. The coating layer 28 is a layer that covers the transmission line body 27. The resin material constituting the coating layer 28 is not particularly limited and can be set as appropriate. For example, the linear transmission member 26 may be a general electric wire having a core wire and a coating layer around the core wire, or it may be a shielded wire, twisted wire, enameled wire, nichrome wire, optical fiber, etc.
[0034] The linear transmission member 26 that transmits electricity may be various signal lines or various power lines. Part of the linear transmission member 26 that transmits electricity may be used as an antenna, coil, etc., that sends signals or power to or receives signals or power from space.
[0035] Furthermore, the linear transmission member 26 may be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member with one transmission path. The linear transmission member 26 may also be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A multi-core wire is a linear transmission member 26 having multiple transmission paths. A multi-core wire may be, for example, a twisted wire, a cable in which multiple linear objects are bundled together and covered with a sheath, etc.
[0036] The sheet 22 and the linear transmission member 26 are fixed together via spot fixing portions 30 that are partially fixed along the extending direction of the linear transmission member 26. Multiple spot fixing portions 30 are provided at intervals from each other along the extending direction of the linear transmission member 26. The spacing of these spot fixing portions 30 is not particularly limited and can be set as appropriate. However, the fixing portions between the sheet 22 and the linear transmission member 26 do not necessarily have to be spot fixing portions 30. The fixing portions between the sheet 22 and the linear transmission member 26 may be provided continuously along the extending direction of the linear transmission member 26.
[0037] The fixing method at the spot fixing portion 30 between the sheet 22 and the linear transmission member 26 may be any fixing method. Such fixing methods may include fixing at the contact portion, fixing at the non-contact portion, or a combination of both. Here, fixing at the contact portion means that the portion where the sheet 22 and the linear transmission member 26 come into contact is stuck together and fixed. Fixing at the non-contact portion is a fixing method that does not involve fixing at the contact portion, for example, by using sewing thread, a cover, adhesive tape, etc. to press the linear transmission member 26 toward the sheet 22 or to sandwich the sheet 22 and the linear transmission member 26 and maintain that state. In the following description, the sheet 22 and the linear transmission member 26 will be described assuming that they are in a state of contact portion fixing.
[0038] The manner in which the contact area is fixed may be indirect, direct, or both may be used in combination in different areas. Indirect fixing of the contact area means that the sheet 22 and the linear transmission member 26 are indirectly attached and fixed to each other via an adhesive, such as an adhesive, tack, or double-sided adhesive tape, provided between them. Direct fixing of the contact area means that the sheet 22 and the linear transmission member 26 are directly attached and fixed to each other without the use of an adhesive or the like. In direct fixing of the contact area, for example, the resin contained in at least one of the sheet 22 and the linear transmission member 26 may be melted to cause them to stick together and be fixed.
[0039] In forming such a state of direct fixation of the contact area, the resin may be melted by heat, for example, or by a solvent. In other words, the state of direct fixation of the contact area may be a state of direct fixation of the contact area by heat, or a state of direct fixation of the contact area by a solvent. Preferably, the state of direct fixation of the contact area by heat is preferred.
[0040] The means for forming the state of direct fixation of the contact area is not particularly limited, and known means such as welding, fusion, and welding can be used. Here, at the spot fixing portion 30 between the sheet 22 and the linear transmission member 26, the sheet 22 and the linear transmission member 26 are fused together. In this case, the fusion layer 23 of the sheet 22 and the outermost layer of the linear transmission member 26 are fused together. The outermost layer of the linear transmission member 26 is a coating layer 28. It is preferable that the material of the coating layer 28 and the material of the fusion layer 23 are compatible. Here, the resin material constituting the coating layer 28 is of the same type as the resin material constituting the fusion layer 23. For example, the resin material constituting the fusion layer 23 and the resin material constituting the coating layer 28 are PVC or polyolefin.
[0041] The sheet 22 has side edges 25 where the linear transmission members 26 are not placed. The linear transmission members 26 are placed in the width direction of the sheet 22, leaving a gap at the side edges 25 of the sheet 22. The linear transmission members 26 are placed in the width direction of the sheet 22, closer to the center than the side edges 25 of the sheet 22. Here, the dimensions of the side edges 25 along the width direction of the sheet 22 are smaller than the diameter of the linear transmission members 26. The dimensions of the side edges 25 along the width direction of the sheet 22 may be the same as or larger than the diameter of the linear transmission members 26.
[0042] The adherend 40 is provided at the location in the vehicle where the wiring member 20 is positioned. The first end of the wiring member 20 extends outward from the first end of the adherend 40. The second end of the wiring member 20 extends outward from the second end of the adherend 40. Either one or both of the first and second ends of the wiring member 20 may be positioned on the adherend 40.
[0043] The adherend 40 is fixed to the sheet 22 of the wiring member 20 by an adhesive member 60. The second surface of the sheet 22 is fixed to the adherend surface 42 of the adherend 40. Here, the adherend surface 42 is made of metal. The adherend 40 is a member that includes a metal member, such as a single metal member or a composite member of a metal member and a resin member. The surface of this metal member is the adherend surface 42. However, the adherend surface 42 may also be made of resin. In this case, the adherend 40 is a member that includes a resin member, such as a single resin member or a composite member of a metal member and a resin member, and the surface of the resin member is the adherend surface 42.
[0044] The adherend 40 may be a vehicle-mounted component that is assembled to the vehicle together with the wiring member 20. The adherend 40 and the wiring member 20 may be transported to the vehicle assembly plant as the adherend 10 with the wiring member attached. For example, the adherend 40 may be a bracket or the like. The adherend 40 may have functions other than fixing the wiring member 20 and the cover 50. Such functions may include, for example, fixing equipment. The adherend 40 may also be provided with a fixing part to the vehicle. If the adherend 40 and the vehicle are screwed together, the fixing part provided on the adherend 40 may be any part used for screw fastening, such as a through hole, screw hole, nut, stud bolt, etc.
[0045] The adherend 40 may be a component that is pre-assembled to the vehicle before the wiring member 20 is assembled to the vehicle. The adherend 40 and the wiring member 20 may be transported separately to the vehicle assembly plant. For example, the adherend 40 may be a body panel, a body frame, or the like.
[0046] The cover 50 covers the linear transmission member 26 from the side opposite to the sheet 22. The linear transmission member 26 is surrounded by the sheet 22 and the cover 50. The linear transmission member 26 is not fixed even though it is in contact with the cover 50. The cover 50 has a cover body portion 52 and an attachment fixing portion 56.
[0047] The cover body portion 52 is the part that covers the wiring member 20. The cover body portion 52 covers the linear transmission member 26 and the sheet 22. Here, the cover body portion 52 is in contact with at least some of the linear transmission member 26. The multiple linear transmission member 26 includes large-diameter linear transmission member 26 and small-diameter linear transmission member 26. The cover body portion 52 is in contact with at least the large-diameter linear transmission member 26. Here, multiple small-diameter linear transmission member 26 are provided. The cover body portion 52 is in contact with some of the small-diameter linear transmission member 26 and not with some of the other small-diameter linear transmission member 26. The portion where the linear transmission member 26 and the cover body portion 52 are in contact with each other is not fixed.
[0048] The adherend fixing portion 56 is the part that is fixed to the adherend 40. The adherend fixing portion 56 is located on the side of the cover body portion 52. Here, the adherend fixing portion 56 and the adherend surface 42 are fixed via the adhesive member 60. Therefore, in this case, the adherend fixing portion 56 is the adherend adhesive portion 56.
[0049] Here, since the adherend surface 42 is a flat surface, the adherend adhesive portion 56 and the portion of the cover body 52 that covers the linear transmission member 26 are separated in the thickness direction of the wiring member 20. The portion of the cover body 52 that covers the linear transmission member 26 protrudes more from the adherend adhesive portion 56 in the thickness direction of the wiring member 20 relative to the adherend surface 42. Here, the cover 50 absorbs the thickness of the wiring member 20 by bending and extending in the thickness direction between the adherend adhesive portion 56 and the portion of the cover body 52 that covers the linear transmission member 26. The cover 50 rises from the adherend adhesive portion 56 toward the portion of the cover body 52 that covers the linear transmission member 26, moving away from the adherend surface 42. Here, the portion between the adherend adhesive portion 56 and the portion of the cover body 52 that covers the linear transmission member 26 is referred to as the rising portion 53.
[0050] The rising portion 53 covers the side edge 25 of the sheet 22. The rising portion 53 may or may not be in contact with the side edge 25 of the sheet 22. If the rising portion 53 and the side edge 25 of the sheet 22 are in contact, the rising portion 53 and the side edge 25 of the sheet 22 may or may not be fixed. In this example, the rising portion 53 and the side edge 25 of the sheet 22 are not fixed.
[0051] The base material constituting the cover 50 can be any of the various sheets described in the section on the base material constituting the sheet 22, such as a solid sheet, a foamed sheet, or a fibrous sheet. The base material constituting the cover 50 may be of the same type as the base material constituting the sheet 22. The base material constituting the cover 50 may be of a different type than the base material constituting the sheet 22. The base material constituting the cover 50 may be a sheet with excellent abrasion resistance. For example, the fibrous sheet used in the second layer 24 of the base material constituting the sheet 22 may be used alone as the base material constituting the cover 50. Alternatively, the base material constituting the cover 50 may be a solid sheet made of resin such as PP or polyamide (nylon), which has higher rigidity than a fibrous sheet.
[0052] The adhesive member 60 fixes both the sheet 22 and the cover 50 to the adherend 40. Here, the area where the cover 50 and the adherend 40 are fixed is located at the same position along the extending direction of the wiring member 20 as the area where the wiring member 20 and the adherend 40 are fixed. The adhesive member 60 includes a first adhesive portion 61 and a second adhesive portion 62. The first adhesive portion 61 is the portion that adheres the sheet 22 and the adherend 40. The second adhesive portion 62 adheres the cover 50 and the adherend 40. The first adhesive portion 61 and the second adhesive portion 62 are separate parts of the adhesive member 60. The first adhesive portion 61 and the second adhesive portion 62 are provided in a series along the width direction of the sheet 22. The first adhesive portion 61 overlaps with the sheet 22. The second adhesive portion 62 protrudes laterally from the sheet 22. The second adhesive portion 62 overlaps with the adherend adhesive portion 56.
[0053] Here, a hot-melt adhesive is used as the adhesive member 60. A hot-melt adhesive is an adhesive that becomes more adhesive at room temperature when heated and softened. However, the adhesive member 60 is not particularly limited as long as it is an adhesive material. For example, the adhesive member 60 may be an adhesive other than a hot-melt adhesive, such as a thermosetting adhesive or an ultraviolet-curing adhesive. Alternatively, the adhesive member 60 may be an adhesive such as double-sided adhesive tape.
[0054] The metal adherend surface 42 of the adherend 40 is in contact with the hot melt adhesive. Also, the second surface of the sheet 22 and the adherend adhesion portion 56 of the cover 50 are in contact with the hot melt adhesive. Here, the second surface of the sheet 22 is the surface of the fiber material sheet. Therefore, some of the hot melt adhesive may seep into the interior of the fiber material sheet. In this case, a so-called anchoring effect is exerted, increasing the fixing strength between the hot melt adhesive and the sheet 22. Similarly, if the base material constituting the cover 50 is a fiber material sheet alone, some of the hot melt adhesive may seep into the adherend adhesion portion 56, and an anchoring effect may be exerted.
[0055] The hot melt adhesive can be heated, for example, using an induction heating device 80, as shown in Figure 3. When high frequency current flows through the coil in the induction heating device 80, the change in magnetic force generates an electric current (eddy current) in the metal member having the adhesion surface 42. The metal member having the adhesion surface 42 is heated by Joule heating caused by this eddy current. The hot melt adhesive in contact with the adhesion surface 42 is then heated by heat transfer from the adhesion surface 42, softens, and adheres to the adhesion surface 42 of the adherend 40, the second surface of the sheet 22, and the adhesion portion 56 of the cover 50.
[0056] At this time, the adhesive portion 56 of the cover 50 may be pressed toward the adhesive surface 42 by the press member 82. This increases the fixing strength between the adhesive portion 56 and the adhesive surface 42. Alternatively, the hot melt adhesive may be heated while the adhesive portion 56 is held between the press member 82 and the adhesive surface 42, and the cover 50 is taut. This makes it easier to maintain the taut state of the cover 50 after it has been fixed. The hot melt adhesive may be pre-bonded to either the adhesive surface 42 of the adherend 40 or the second surface of the sheet 22 before the adhesive surface 42 is fixed to the sheet 22 and the adhesive surface 42 is fixed to the cover 50.
[0057] In the width direction of the sheet 22, the dimensions of the area where the cover 50 and the adherend 40 are fixed via the second adhesive portion 62 are larger than the dimensions of the area of the side edge 25 of the sheet 22 where the linear transmission member 26 is not placed. In the example shown in Figure 2, dimension W1 is the dimension of the area of the side edge 25 of the sheet 22 in the width direction. Dimension W1 is the distance between the outermost linear transmission member 26 and the side edge 25 of the sheet 22 in the width direction of the sheet 22. Also, in the example shown in Figure 2, dimension W2 is the dimension of the area where the cover 50 and the adherend 40 are fixed via the second adhesive portion 62 in the width direction of the sheet 22. Dimension W2 is the dimension of the part of the cover 50 that is bonded to the adhesive member 60. As shown in Figure 2, dimension W2 is larger than dimension W1. Generally, the larger the bonding area with the adhesive member 60, the greater the fixing strength. While it would be desirable to have a fixing margin of dimension W2 for securing the cover 50, this fixing margin is provided on the adherend 40 side, rather than on the sheet 22. As a result, a fixing margin of dimension W2 does not need to be provided on the sheet 22, and the sheet 22 can be made smaller.
[0058] The cover 50 is fixed in contact with the linear transmission member 26 while being stretched along the width direction of the sheet 22. As a result, the cover 50 presses the linear transmission member 26 toward the adherend 40. Tensile stress is applied to the cover 50 along the width direction of the sheet 22. A force opposing the tensile stress is applied to the cover 50 from the second adhesive portion 62. At the contact portion between the cover 50 and the linear transmission member 26, the linear transmission member 26 pushes the cover 50 away from the adherend 40, and as a reaction force, a force toward the adherend 40 is applied to the linear transmission member 26.
[0059] More specifically, as shown in Figure 3, the cover 50 before being fixed to the adherend 40 is flatter than the cover 50 after it is fixed to the adherend 40. When both side edges of the cover 50 are fixed to the adherend 40, the cover 50 bends and deforms so that the middle portion of the cover 50 absorbs the thickness of the wiring member 20. At this time, the cover 50 deforms so that tensile stress remains in the cover 50 along the width direction of the sheet 22. Then, with both side edges of the cover 50 fixed to the adherend 40 via the second adhesive portion 62, the cover 50 is in a deformed state and is maintained in a state where tensile stress is applied to the cover 50 along the width direction of the sheet 22. A force that opposes the tensile stress is applied to the cover 50 from the second adhesive portion 62. The second adhesive portion 62 also has fixing strength (mainly tensile shear adhesive strength) sufficient to support the tensile stress of the cover 50.
[0060] When the cover 50 is taut, even in a position where the cover body 52 does not cover the linear transmission member 26 from vertically above, the cover body 50 is prevented from sagging and separating from the wiring member 20. Examples of positions in which the cover body 52 does not cover the linear transmission member 26 from vertically above include a position in which the linear transmission members 26 are aligned vertically (a position in which the left-right direction in Figure 2 is the vertical direction), or a position in which the linear transmission members 26 are located vertically above the cover 50 (a position in which the bottom of Figure 2 is vertically above, and the top of Figure 2 is vertically below).
[0061] If there are multiple linear transmission members 26, it is not necessary for all of them to be in contact with the cover 50. The cover 50 only needs to be in contact with at least one linear transmission member 26 and press down only the linear transmission member 26 that is in contact with it. In this case, the cover 50 is in contact with the large-diameter linear transmission member 26 and some of the small-diameter linear transmission members 26, and is pressing down on these linear transmission members 26.
[0062] More specifically, the heights of the wiring members 20, particularly the heights of the multiple linear transmission members 26, are not aligned in the width direction of the sheet 22. The outer surfaces of the larger diameter linear transmission members 26 protrude more in the thickness direction of the wiring members 20 than the outer surfaces of the smaller diameter linear transmission members 26. As a result, the portion of the cover body 52 that contacts the larger diameter linear transmission members 26 protrudes more in the thickness direction of the wiring members 20 than other portions. As the sheet 22 is assumed to be taut, the cover body 52 extends straight outwards from the portion that contacts the larger diameter linear transmission members 26, inclined relative to the surface to be attached 42. The cover body 52 then bends toward the body adhesive portion 56 toward the body to be attached 40, while contacting the smaller diameter linear transmission members 26 located at the ends. The cover 50 contacts the larger diameter linear transmission members 26 and the smaller diameter linear transmission members 26 located at the ends, but does not contact the smaller diameter linear transmission members 26 between them.
[0063] In the extending direction of the wiring member 20, the area where the adhesive member 60 is provided can be set as appropriate. In the example shown in Figure 1, adhesive members 60 are provided at both ends of the adherend 40 along the extending direction of the wiring member 20. The wiring member 20 is positioned so that the spot fixing portion 30 does not overlap with the adhesive member 60. The adhesive member 60 is located between the spot fixing portions 30. This makes it difficult for heat from the adhesive member 60 to be transferred to the spot fixing portions 30. The wiring member 20 may also be positioned so that the spot fixing portion 30 overlaps with the adhesive member 60.
[0064] The adhesive members 60 for fixing the sheet 22 to the adherend 40 and the adhesive members 60 for fixing the cover 50 to the adherend 40 may be provided separately so as not to come into contact with each other. The adhesive members 60 for fixing the sheet 22 to the adherend 40 and the adhesive members 60 for fixing the cover 50 to the adherend 40 may be different. In this case, the area to which the cover 50 and the adherend 40 are fixed may be provided at a different position along the extending direction of the wiring member 20 from the area to which the sheet 22 and the adherend 40 are fixed. Along the extending direction of the wiring member 20, the area to which the cover 50 and the adherend 40 are fixed may be larger or smaller than the area to which the sheet 22 and the adherend 40 are fixed. For example, in the example shown in Figure 1, adhesive members 60 are provided at two points on both ends of the adherend 40 along the extending direction of the wiring member 20. The cover 50 and the adherend 40 may be fixed via adhesive members 60 provided at another position between these two points.
[0065] The cover 50 and the object to be adhered 40 may be fixed together via a series of adhesive members 60 arranged to connect one of the two adhesive members 60 shown in Figure 1. In this case, the adhesive members 60 may be arranged in a rectangular frame shape in a plan view.
[0066] <Effects, etc.> With the wiring member-equipped adherend 10 configured as described above, the cover 50 is fixed to the adherend 40, making it easier to secure the necessary fixing strength of the cover 50, and allowing the area for fixing the cover 50 in the sheet 22 to be omitted or reduced in size. This makes it possible to reduce the size of the sheet 22 while suppressing a decrease in the fixing strength of the cover 50.
[0067] Furthermore, in the width direction of the sheet 22, the dimensions of the area where the cover 50 and the adherend 40 are fixed via the second adhesive portion 62 are larger than the dimensions of the side edge portion 25 of the sheet 22 where the linear transmission member 26 is not placed. As a result, the area of the cover 50 that has dimensions larger than the side edge portion 25 of the sheet 22 is fixed to the adherend 40.
[0068] Furthermore, the cover 50 is fixed in a state where it is stretched along the width direction of the sheet 22 while in contact with at least some of the linear transmission members 26. This allows the cover 50 to press the wiring members 20 toward the adherend 40.
[0069] Furthermore, the cover 50 and the sheet 22 are separate components, and the cover 50 is fixed to the adherend 40 on both sides of the wiring member 20. This makes it easy to use a base material for the cover 50 that has different physical properties from the base material for the sheet 22.
[0070] Furthermore, both the first fixing member that secures the sheet 22 to the adherend 40 and the second fixing member that secures the cover 50 to the adherend 40 are adhesive members 60. This allows the wiring member 20, the adherend 40, and the cover 50 to be easily fixed together via the adhesive members 60.
[0071] [Embodiment 2] A wiring-equipped adherend according to Embodiment 2 will now be described. Figure 4 is a cross-sectional view showing a wiring-equipped adherend 110 according to Embodiment 2. Figure 5 is an explanatory diagram showing the manufacturing process of the wiring-equipped adherend 110. In this description of the embodiment, the same reference numerals are used for components similar to those described so far, and their descriptions are omitted. The same applies to the following descriptions of each embodiment and each variation.
[0072] In this example, the substrate constituting the cover 150 and the substrate constituting the sheet 22 are not different substrates but the same substrate, which is different from the adherend 10 with the wiring member described above. The cover 150 is provided by folding back a portion of the substrate constituting the sheet 22. The cover 150 is fixed to the adherend 40 only on one side of the wiring member 20 (the side on which the sheet 22 and the cover 150 are not connected). In the cover 150, the adherend adhesive portion 56 is provided only on one side of the wiring member 120. As a result, it is not necessary to fix the cover 150 and the adherend 40 on one side (the side on which the sheet 22 and the cover 150 are connected), making the fixing work between the cover 150 and the adherend 40 easier.
[0073] The portion of the base material that becomes the cover 150 is longer in the width direction of the sheet 22 than the portion that becomes the sheet 22. The width dimension of the region of the base material that has the portion that becomes the sheet 22 and the portion that becomes the cover 150 is longer than twice the width dimension of the portion that becomes the sheet 22.
[0074] In the base material, the portion that will become the cover 150 may be partially provided along the extending direction of the portion that will become the sheet 22. That is, if the relationship between the cover 150 and the sheet 22 is the same as the relationship between the cover 50 and the sheet 22 shown in Figure 1, the portion that will become the cover 150 may be partially provided in the base material in the portion corresponding to the area of the cover 50 shown in Figure 1. The base material may have a region along the extending direction that has only the portion that will become the sheet 22, and a region that has both the portion that will become the sheet 22 and the portion that will become the cover 150. The base material may have a region with a small width dimension and a region with a large width dimension along the extending direction. The region with a small width dimension corresponds to the region that has only the portion that will become the sheet 22, and the region with a large width dimension corresponds to the region that has both the portion that will become the sheet 22 and the portion that will become the cover 150.
[0075] In the example shown in Figure 4, the portion of the substrate that becomes the cover 150 has the same structure as the portion that becomes the sheet 22, that is, a two-layer structure including the first layer 23 and the second layer 24. The portion that becomes the cover 150 may have a different structure from the portion that becomes the sheet 22. For example, the portion that becomes the sheet 22 may include both the first layer 23 and the second layer 24, while the portion that becomes the cover 150 may not include the first layer 23 and consist only of the second layer 24.
[0076] [Embodiment 3] A wiring-equipped adherend according to Embodiment 3 will now be described. Figure 6 is a cross-sectional view showing a wiring-equipped adherend 210 according to Embodiment 3. Figure 7 is an explanatory diagram showing the manufacturing process of the wiring-equipped adherend 210.
[0077] The adherend 210 with wiring components in this example differs from the adherend 10 with wiring components in that the sheet 22 and the cover 250 are bonded together. The cover 250 has a sheet bonding portion 54 and an adherend bonding portion 56. The sheet bonding portion 54 is the portion of the cover 250 that overlaps with the side edge portion 25 of the sheet 22. The sheet bonding portion 54 is bonded to the side edge portion 25 of the sheet 22. The adherend bonding portion 56 protrudes outward from the sheet bonding portion 54 along the width direction of the sheet 22, beyond the side edge portion 25 of the sheet 22. In this example as well, the adherend bonding portion 56 is bonded to the adherend 40 via a second bonding portion 62. This allows the cover 250 to be fixed to both the adherend 40 and the sheet 22. The sheet bonding portion 54 may be fixed to the entire side edge portion 25, or to only a part of the side edge portion 25.
[0078] In this example, the sheet adhesive portion 54 is bonded to the sheet 22 via an adhesive member 360 that bonds the sheet 22 and the cover 250 to the adherend 40. Therefore, in addition to the first adhesive portion 61 and the second adhesive portion 62, the adhesive member 360 further has a third adhesive portion 63. The third adhesive portion 63 bonds the sheet adhesive portion 54 to the side edge portion 25 of the sheet 22. The sheet adhesive portion 54 is parallel to the sheet 22. The sheet adhesive portion 54 may be inclined with respect to the sheet 22.
[0079] In the example shown in Figure 6, the dimensions of the adherend adhesive portion 56 are larger than the dimensions of the sheet adhesive portion 54 in the width direction of the sheet 22. However, the dimensions of the adherend adhesive portion 56 may be the same as or smaller than the dimensions of the sheet adhesive portion 54 in the width direction of the sheet 22. The sheet adhesive portion 54 and the adherend adhesive portion 56 may together provide the width necessary for fixing the cover 250. The adherend adhesive portion 56 alone may also provide the width necessary for fixing the cover 250.
[0080] The sheet adhesive portion 54 may be provided even before the wiring member 20 is fixed to the adherend 40. In other words, the sheet 22 and the cover 250 may be fixed via the sheet adhesive portion 54 before the wiring member 20 is fixed to the adherend 40, thereby forming a covered wiring member 200.
[0081] The covered wiring member 200 comprises a sheet 22, a wiring member 20 including a linear transmission member 26 fixed to the sheet 22, and a cover 250 covering the wiring member 20. The cover 250 has a sheet adhesive portion 54 and a protruding portion 56B. The sheet adhesive portion 54 is the portion that overlaps with the side edge 25 of the sheet 22 on at least one side of the wiring member 20. The sheet adhesive portion 54 is the portion that is bonded to the side edge 25 of the sheet 22 via an adhesive member 363. The protruding portion 56B is the portion that protrudes outward from the sheet adhesive portion 54 along the width direction of the sheet 22, beyond the side edge 25 of the sheet 22.
[0082] With the covered wiring member 200, the sheet adhesive portion 54 is provided, allowing the cover 250 to be temporarily held on the wiring member 20. Furthermore, the protruding portion 56B is provided, allowing the protruding portion 56B and the adherend 40 to be fixed together, forming an adherend adhesive portion 56. In addition to the sheet adhesive portion 54 of the cover 250 being fixed to the sheet 22, the protruding portion 56B is also fixed to the adherend 40, which allows the sheet 22 to be made smaller while suppressing a decrease in the fixing strength of the cover 250.
[0083] The adhesive member 363 protrudes laterally beyond the side edge 25 of the sheet 22. The adhesive member 363 does not necessarily have to protrude laterally beyond the side edge 25 of the sheet 22. The adhesive member 363 is the portion that becomes the third adhesive portion 63 in the adherend 210 with the wiring member. For example, as shown in Figure 7, the adhesive member 363 is provided separately from the adhesive member 60. The adhesive member 363 may be the same type of adhesive member as the adhesive member 60. When the sheet 22 and the adherend adhesive portion 56 are bonded to the adherend 40 via the adhesive member 60, the adhesive member 363 may be integrated with the adhesive member 60. The adhesive member 363 may be a different type of adhesive member than the adhesive member 60.
[0084] The sheet adhesive portion 54 may not be provided before the wiring member 20 is fixed to the adherend 40, but may be provided when the wiring member 20 and cover 250 are fixed to the adherend 40. For example, as shown in Figure 3, when the wiring member 20 and cover 50 are fixed to the adherend 40, a part of the adhesive member 60 may be pressed by the press member 82 and protrude beyond the first surface of the sheet 22 in the thickness direction of the wiring member 20. In this case, the protruding part of the adhesive member 60 may enter between the first surface of the sheet 22 and the cover 50, fixing the first surface of the sheet 22 and the cover 50, resulting in the adherend 210 with wiring member shown in Figure 6.
[0085] [Differentiation] Up until now, it has been explained that in the width direction of the sheet 22, the dimensions of the area where the cover 50 and the adherend 40 are fixed via the second adhesive portion 62 are larger than the dimensions of the area of the side edge 25 of the sheet 22 where the linear transmission member 26 is not placed. However, this is not an essential configuration. In the width direction of the sheet 22, the dimensions of the area of the side edge 25 of the sheet 22 where the linear transmission member 26 is not placed may be the same as or larger than the dimensions of the area where the cover 50 and the adherend 40 are fixed via the second adhesive portion 62.
[0086] Furthermore, although the cover 50 has been described as being fixed in a state where it is in contact with the linear transmission member 26 and stretched along the width direction of the sheet 22, this is not an essential configuration. The cover 50 does not have to be stretched along the width direction of the sheet 22. In this case, the cover 50 may hang down toward the sheet 22 on the side of the large-diameter linear transmission member 26. The cover 50 may be in contact with all of the linear transmission members 26.
[0087] Furthermore, although the first and second fixing members have been described as both being adhesive members 60, this is not a mandatory configuration. Either one or both of the first and second fixing members may be fixing members other than adhesive members 60. For example, a clamp may be used as such a fixing member. In this case, the first fixing member may directly fix only the sheet 22 of the sheet 22 and cover 50 to the object to be attached 40. Similarly, the second fixing member may directly fix only the cover 50 of the sheet 22 and cover 50 to the object to be attached 40. Alternatively, the second fixing member may fix at least the portion of the cover 50 that does not overlap with the sheet 22 to the object to be attached 40, rather than directly fixing the sheet 22.
[0088] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of Symbols]
