[0021] [Description of embodiments of this disclosure]

[0022] The embodiments of this disclosure are first described by listing them.

[0023] The flat wiring component disclosed herein is described below.

[0024] (1) A flat wiring component comprising: a plurality of linear transmission components; a substrate having a fixing surface; and a shielding component surrounding the plurality of linear transmission components and the substrate, wherein the plurality of linear transmission components are directly fixed to the fixing surface in a parallel state, and the shielding component includes an overlapping side and an overlapping target side, wherein the overlapping side and the overlapping target side overlap without being separated by the substrate.

[0025] According to this flat wiring component, the overlapping side and the overlapping target side overlap without being separated by the substrate, thus reducing the gap between the overlapping side and the overlapping target side. Therefore, when multiple linear transmission components fixed to the substrate are surrounded by a shielding component, the gap at the joint of the shielding component can be minimized.

[0026] (2) In the flat wiring component of (1), the shielding component may include a first shielding sheet and a second shielding sheet, the overlapping side includes a side portion and a side portion of the first shielding sheet, the overlapping target side includes a side portion and a side portion of the second shielding sheet, the side portion of the first shielding sheet and the side portion of the second shielding sheet are kept in a state of overlapping outside the side portion of the substrate, and the other side portion of the first shielding sheet and the other side portion of the second shielding sheet are kept in a state of overlapping outside the other side portion of the substrate.

[0027] In this case, the overlap of the first and second shielding sheets makes it easy to surround multiple linear transmission components and substrates.

[0028] (3) In the flat wiring component of (1), the shielding component may include a shielding sheet, the overlapping side is one side of the shielding sheet, the overlapping object side is the other side of the shielding sheet, and the shielding sheet surrounds the plurality of linear transmission components and the substrate in a manner that is more than one circumference, and the shielding sheet is kept in a state in which one side of the shielding sheet overlaps with the other side.

[0029] Therefore, a single shielding sheet is used to surround multiple linear transmission components and the substrate.

[0030] (4) The flat wiring component according to any one of (1) to (3) may also include a plurality of segments arranged separately from each other along the extension direction of the plurality of linear transmission components.

[0031] This allows for a lighter substrate and also reduces material costs.

[0032] (5) The flat wiring component according to any one of (1) to (4) may also include bare wires surrounded by the shielding component.

[0033] The shielded components can be easily grounded using bare wires. Additionally, it reduces the amount of bare wires exposed from the shielded components.

[0034] (6) In the flat wiring component of (5), the shielding component may also be a stacked structure including a resin layer and a metal layer, wherein the metal layer is located on the inner periphery side of the resin layer.

[0035] The resin layer can strengthen the shielding components and provide insulation from the outside. Additionally, the inner circumferential metal layer can be made to contact the bare overhead wires to achieve conductivity.

[0036] (7) In the flat wiring component of (6), the shielding component may include a conductive adhesive layer disposed on the inner peripheral side of the metal layer, and the overlapping side and the overlapping object side are kept in a state of overlapping through the conductive adhesive layer.

[0037] In this case, the shielding component can be bonded to the bare busbar via a conductive adhesive layer. The conductive adhesive layer easily makes contact with the bare busbar over a large area. Furthermore, the overlapping sides and the overlapping target sides are kept in an overlapping state via the conductive adhesive layer. Therefore, gaps between the overlapping sides and the overlapping target sides can be suppressed, further improving the shielding effect.

[0038] (8) In the flat wiring component of (6), the shielding component may include an adhesive layer disposed on the inner peripheral side of the metal layer, the adhesive layer extending into a striped area intersecting the bare wire, and the overlapping side and the overlapping object side being maintained in a state of overlapping through the adhesive layer.

[0039] In this configuration, the shielding components can be bonded to the substrate, multiple linear transmission components, and bare overhead wires via an adhesive layer. Because the adhesive layer intersects with the bare overhead wires, it facilitates contact between the bare overhead wires and the exposed metal layer between the adhesive layer and the extended striped area. Furthermore, the overlapping sides and the overlapping target sides are held in an overlapping state via the adhesive layer. At this time, the extended striped area of ​​the adhesive layer intersects with the extending direction of the overlapping sides and the overlapping target sides, thus suppressing gaps between the overlapping sides and the overlapping target sides and further improving the shielding effect.

[0040] (9) The flat wiring component according to any one of (6) to (8) may also include an adhesive layer disposed on the inner peripheral side of the metal layer, wherein the shielding component is bonded to the bare busbar via the adhesive layer, thereby holding the bare busbar in a state along the plurality of linear transmission components.

[0041] In this case, even if the bare wires are not fixed to the substrate, the shielding components can keep the bare wires along the linear transmission components.

[0042] (10) In the flat wiring component of (9), the shielding component can also hold the bare scrambled wires in position on the substrate.

[0043] Therefore, bare overhead wires and multiple linear transmission components can be easily kept in a parallel configuration on the substrate.

[0044] [Details of embodiments of this disclosure]

[0045] Hereinafter, specific examples of the flat wiring components of this disclosure will be described with reference to the accompanying drawings. Furthermore, this disclosure is not limited to these examples, but is shown in the claims and is intended to include all modifications equivalent to and within the scope of the claims.

[0046] [Implementation Method 1]

[0047] The flat wiring component according to Embodiment 1 will be described below. Figure 1 This is a top view of the flat wiring component 10. Figure 2 This is an exploded view of the flat wiring component 10. Figure 3 yes Figure 1 Sectional view along line III-III, Figure 4 yes Figure 1 The cross-sectional view along line IV-IV. Additionally, in each figure, descriptions are sometimes exaggerated or simplified for illustrative purposes. For example, the thickness of each layer of the shielding component 40 is exaggeratedly depicted as thicker.

[0048] <Overall Structure>

[0049] The flat cabling component 10 includes multiple linear transmission components 20, a substrate 30, and a shielding component 40.

[0050] Multiple linear transmission components 20 are held in a parallel configuration by being fixed to the substrate 30. A shielding component 40 surrounds the multiple linear transmission components 20 and the substrate 30. Thus, the shielding component 40 provides electromagnetic shielding for the multiple linear transmission components 20. Preferably, a de-scratching wire 28 is surrounded by the shielding component 40. The de-scratching wire 28 contacts and conducts through the shielding component 40 from its inner side. The de-scratching wire 28 extends outside the shielding component 40, allowing the shielding component 40 to be grounded via the de-scratching wire 28. Here, the grounding type of the de-scratching wire 28 can be either one-end grounding or two-end grounding, but for improved shielding effectiveness, two-end grounding is preferred.

[0051] To ensure good electromagnetic shielding of the shielding component 40, it is desirable to minimize the gap at the joints of the shielding component. This disclosure includes methods for minimizing this gap.

[0052] The following is a more detailed explanation.

[0053] <About linear transmission components>

[0054] The linear transmission component 20 is a linear member that transmits electricity or light. It is envisioned that the linear transmission component 20 is a member that connects components in a vehicle to each other. The linear transmission component 20 includes a transmission line body 22 and a cover layer 24. The transmission line body 22 is the transmission path for transmitting electricity or light. For example, if the linear transmission component 20 is an electrical wire, the transmission line body 22 is a conductor core. The conductor core is composed of one or more wires. The wires are formed using materials such as copper, copper alloys, aluminum, and aluminum alloys. Alternatively, if the linear transmission component 20 is an optical fiber, the transmission line body 22 consists of a core and a cladding. The cover layer 24 is a layer that covers the transmission line body 22. For example, if the linear transmission component 20 is an electrical wire, the cover layer 24 is an insulating coating. The cover layer 24 is, for example, made of a resin material. The resin material constituting the cover layer 24 is not particularly limited and can be appropriately chosen. The linear transmission component 20 can be, for example, a general electrical wire with a core wire and a surrounding covering layer, or it can be a shielded wire, stranded wire, enameled wire, nickel-chromium alloy wire, optical fiber, etc. The linear transmission component 20 can also be a component made by bundling multiple wires together.

[0055] The linear transmission component 20 for transmitting electricity can also be various signal lines or power lines. A part of the linear transmission component 20 for transmitting electricity can also be used as an antenna, coil, etc. to transmit or receive signals or electricity into or from space.

[0056] Alternatively, the linear transmission component 20 can also be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission component 20 with one transmission path. The linear transmission component 20 can 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 component 20 with multiple transmission paths. For example, a multi-core wire can also be a stranded wire, a cable that combines multiple linear objects and covers them with a sheath, etc.

[0057] A connector 26 is provided at the end of the linear transmission component 20, for example. The connector 26 includes a connector housing made of insulating resin and connector terminals that serve as transmission components. The end of the linear transmission component 20 is connected to the connector terminals. The connector housing holds a plurality of connector terminals. Thus, the plurality of connector terminals are held in a predetermined arrangement. The connector 26 is connected to a connector provided on the flat wiring component 10.

[0058] It should be noted that the flat cabling component 10 may include multiple linear transmission components 20, and their number is not particularly limited. In addition, the flat cabling component 10 may also include multiple linear transmission components 20 of different thicknesses or types.

[0059] <About the substrate>

[0060] The substrate 30 has a fixing surface 31. Multiple linear transmission components 20 are arranged in a parallel configuration and directly fixed to the fixing surface 31 at their contact points. The substrate 30 is only required to directly fix the contact points of the linear transmission components 20; the material and structure are not particularly limited. Regarding the material constituting the substrate 30, it is here formed of a resin material. Since the substrate 30 is formed of a resin material, it can be considered to not contain metal.

[0061] The substrate 30 can be a single-layer structure, a two-layer structure, or a multi-layer structure with three or more layers. The substrate 30 may also include at least a welding layer. The linear transmission component 20 is welded and fixed to the welding layer. The welding layer contains a resin material, preferably a thermoplastic resin material. The resin material of the welding layer softens and welds to the object being welded. The type of resin material is not particularly limited and can be polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc.

[0062] The structure of the welded layer is not particularly limited. For example, the welded layer can also be a solid sheet with a uniform solid cross-section (also called a non-foamed sheet or solid sheet, etc.). Alternatively, the welded layer can also be a foamed sheet, etc. Alternatively, the welded layer can also be a sheet of fibrous material such as woven fabric, fabric, or non-woven fabric. One surface of the first layer is the fixing surface 31 of the substrate 30.

[0063] In this embodiment, an example of a single-layer structure for the substrate 30 is described. Additional layers may also be added to the substrate 30. These additional layers may be formed of a different material than the weld layer, or have a different structure. The additional layers enhance the functionality of the weld layer, or add functionality to the substrate 30 that the weld layer does not possess.

[0064] The substrate 30 can also be a flexible component. For example, the substrate 30 can be bent in the thickness direction in a manner that allows it to follow the bending of the linear transmission component 20.

[0065] The paths of the multiple linear transmission components 20 are set according to the positions of the components that become the connection destinations. By fixing the multiple linear transmission components 20 to the substrate 30, the multiple linear transmission components 20 are kept in a state along wiring paths corresponding to the positions of the components that become their respective connection destinations.

[0066] In this embodiment, multiple linear transmission components 20 are fixed to the fixing surface 31 in a parallel configuration. The paths of the multiple linear transmission components 20 can be straight paths only, or they can be a combination of straight and curved paths. Therefore, the fixing surface 31 can hold the multiple linear transmission components 20 in a parallel configuration along a straight path, or it can hold the multiple linear transmission components 20 in a parallel configuration along a path that combines straight and curved paths. In this embodiment, the multiple linear transmission components 20 are held in a parallel configuration along a straight path. The multiple linear transmission components 20 can be in contact with each other or separated from adjacent linear transmission components.

[0067] It should be noted that, here, multiple linear transmission components 20 extend along the same path. Alternatively, some linear transmission components 20 may branch off from other linear transmission components 20. The branching point can be on the substrate 30 or at a location away from the substrate 30.

[0068] <Regarding Fixed Structures>

[0069] Multiple linear transmission components 20 are directly fixed to the fixing surface 31 of the substrate 30 at their contact points. Direct fixing at contact points means that the linear transmission components 20 and the substrate 30 are directly and tightly bonded without being separated by adhesives or the like. In direct fixing at contact points, for example, it is considered to achieve bonding by melting the resin contained in at least one of the substrate 30 and the linear transmission components 20. In this embodiment, the linear transmission components 20 and the substrate 30 are fixed via a welding fixing portion 38.

[0070] When the contact area is directly fixed, the resin may be melted by heat or by a solvent. That is, the direct fixing of the contact area can be based on heat or on solvent. The direct fixing of the contact area based on heat is preferred.

[0071] At this time, there is no particular limitation on the means of directly fixing the contact parts, and known methods such as welding can be used. For example, when forming a heat-based direct fixing state of the contact parts by welding, various welding methods such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding can be used. Furthermore, when the contact parts are directly fixed by these methods, the linear transmission component 20 and the substrate 30 become directly fixed by these methods. Specifically, for example, when the contact parts are directly fixed by ultrasonic welding, the linear transmission component 20 and the substrate 30 become directly fixed by ultrasonic welding. Therefore, welding is one method of directly fixing the contact parts.

[0072] Here, the outermost layer of the linear transmission component 20 is fused to the fixing surface 31 of the substrate 30. In the linear transmission component 20, the outermost layer is a cover layer 24 located at the outermost periphery. The cover layer 24 is made of a material that can be fused to the fixing surface 31 in the substrate 30. The type of resin material constituting the cover layer 24 can also be the same as the resin material constituting the fixing surface 31.

[0073] The linear transmission component 20 can be fixed intermittently or continuously relative to the substrate 30 along the extension direction of the linear transmission component 20.

[0074] Alternatively, linear transmission components 20 can be fixed on both sides of the substrate 30.

[0075] <About Split Pieces>

[0076] The substrate 30 includes a plurality of segmented pieces 32 arranged separately from each other along the extending direction of the plurality of linear transmission members 20. Figure 2 The diagram shows three segments 32. The number of segments 32 in the flat wiring component 10 is arbitrary; it can be two or more.

[0077] The length of the direction in which the segment 32 extends orthogonally to the extension direction of the linear transmission member 20 is sufficient to maintain the multiple linear transmission members 20 in a parallel state; for example, it can be the sum of the diameters of the multiple linear transmission members 20 or more.

[0078] The length of the segment 32 along the extension direction of the linear transmission member 20 can be as small as possible to ensure sufficient strength to maintain the multiple linear transmission members 20, for example, it can be 1cm to 10cm. For example, the length of the segment 32 along the extension direction of the linear transmission member 20 can also be smaller than the length of the segment 32 in the direction orthogonal to the extension direction of the linear transmission member 20.

[0079] The spacing between the multiple segments 32 can be any size that allows the multiple linear transmission components 20 to be kept in a parallel state between the segments 32, for example, it can be 2cm to 30cm.

[0080] From the viewpoint of reducing material costs of substrate 30 and lightweighting of flat wiring component 10, it is preferable that the spacing of the plurality of segments 32 is longer than the length of the segments 32 along the extension direction of the linear transmission component 20.

[0081] It should be noted that it is not necessary for multiple segment pieces 32 to exist between one end and the other end of the linear transmission component 20; alternatively, only one substrate 30 may be provided between one end and the other end of the linear transmission component 20.

[0082] <About shielding components>

[0083] The shielding member 40 surrounds multiple linear transmission members 20 and the substrate 30. That is, the shielding member 40 is an extended sheet-like component. The shielding member 40 is not a seamless cylindrical component, but rather an extended sheet-like component. Therefore, with the shielding member 40 surrounding the multiple linear transmission members 20 and the substrate 30 for more than one circumference, the sides are connected to each other to form a cylindrical shape.

[0084] In this embodiment, the shielding member 40 includes an overlapping side 44 and an overlapping target side 48. When the overlapping side 44 and the overlapping target side 48 overlap, if a substrate 30 is sandwiched between them, a gap corresponding to the thickness of the substrate 30 will be generated between the shielding members 40, which may become a cause of electromagnetic wave leakage. Therefore, the overlapping side 44 and the overlapping target side 48 overlap without being separated by the substrate 30.

[0085] In this embodiment, the shielding component 40 includes a first shielding plate 42 and a second shielding plate 46.

[0086] The widths of the first shielding plate 42 and the second shielding plate 46 are set to exceed the width of the substrate 30. Therefore, the two sides of the first shielding plate 42 and the second shielding plate 46 can be located beyond the substrate 30 in the width direction.

[0087] The lengths of the first shielding plate 42 and the second shielding plate 46 in the longitudinal direction of the linear transmission component 20 can also be set to exceed the length of the area where the plurality of segmented plates 32 exist. In this case, the first shielding plate 42 and the second shielding plate 46 can cover the entire area of ​​the plurality of linear transmission components 20 held by the plurality of segmented plates 32. However, a portion of the plurality of segmented plates 32 can also be located outside the first shielding plate 42 and the second shielding plate 46.

[0088] One side and the other side of the first shielding plate 42 are overlapping sides 44. For example, a plurality of segmented plates 32 and a plurality of linear transmission components 20 are disposed on the first shielding plate 42. The segmented plates 32 are disposed on the first shielding plate 42 in a contact manner. The two sides of the first shielding plate 42 located outside the two sides of the plurality of segmented plates 32 are overlapping sides 44.

[0089] One side and the other side of the second shielding plate 46 are overlapping object sides 48. For example, the second shielding plate 46 covers the plurality of segmented pieces 32 and the plurality of linear transmission members 20 on the first shielding plate 42. The second shielding plate 46 is configured to contact the plurality of linear transmission members 20. The two sides of the second shielding plate 46 located outside the two sides of the plurality of segmented pieces 32 are overlapping object sides 48.

[0090] On the outer side of the other side of the multiple segmented pieces 32, the overlapping side 44, which is the other side of the first shielding piece 42, and the overlapping object side 48, which is the other side of the second shielding piece 46, remain in an overlapping state.

[0091] Thus, the multiple linear transmission components 20 are surrounded by the first shielding plate 42 and the second shielding plate 46. In addition, on the outer side of the arrangement direction of the multiple linear transmission components 20, the first shielding plate 42 and the second shielding plate 46 overlap without being separated by the substrate 30, thereby minimizing the gap between the seam of the first shielding plate 42 and the second shielding plate 46.

[0092] The structure that keeps the overlapping side 44 and the overlapping object side 48 in an overlapping state can be implemented by any structure. For example, the overlapping side 44 and the overlapping object side 48 can also be implemented by an adhesive layer, adhesive, glue, or welding.

[0093] In this embodiment, the first shielding sheet 42 and the second shielding sheet 46 have an adhesive layer 41c. The overlapping side 44 and the overlapping object side 48 are held in an overlapping state via the adhesive layer 41c.

[0094] More specifically, the first shielding sheet 42 and the second shielding sheet 46 constituting the shielding component 40 are respectively laminated structures comprising a resin layer 41a and a metal layer 41b. The metal layer 41b is a metal foil, such as aluminum foil or copper foil. The resin layer 41a is superimposed on the metal layer 41b. The resin layer 41a reinforces the metal layer 41b. In addition, the metal layer 41b is insulated from one of its main surfaces.

[0095] The metal layer 41b is located on the inner periphery side of the resin layer 41a. That is, the resin layer 41a is located on the outer periphery side of the metal layer 41b, and the metal layer 41b is insulated from the outside by the resin layer 41a.

[0096] The first shielding sheet 42 and the second shielding sheet 46 constituting the shielding component 40 each include an adhesive layer 41c disposed on the inner peripheral side of the metal layer 41b.

[0097] The adhesive layer 41c preferably extends into a striped region. That is, it is preferable that the plurality of strip-shaped adhesive portions of the adhesive layer 41c extend in a parallel manner with intervals between them. In this case, the first shielding sheet 42 and the second shielding sheet 46 can adhere to other portions where the adhesive layer 41c is present. Furthermore, the metal layer 41b is exposed in the gaps between the strip-shaped adhesive portions of the adhesive layer 41c. Therefore, the metal layer 41b can make conductive contact with other conductive portions in the gaps of the adhesive layer 41c.

[0098] Preferably, the direction of the stripe extension of the adhesive layer 41c, i.e. the direction of the extension of the strip adhesive portion, intersects with the extension direction of the linear transmission component 20.

[0099] The overlapping side 44 and the overlapping object side 48 are bonded together via the adhesive layer 41c. In this case, when the stripes of the adhesive layer 41c, i.e. the strip-shaped adhesive portion, intersect the extending direction of the overlapping side 44 and the overlapping object side 48, the overlapping side 44 and the overlapping object side 48 can be easily bonded together without gaps.

[0100] Furthermore, if the direction in which the stripes of the adhesive layer 41c extend on the overlapping side 44 intersects the direction in which the stripes of the adhesive layer 41c extend on the overlapping object side 48, then the overlapping side 44 and the overlapping object side 48 can be bonded more easily without gaps.

[0101] It should be noted that the adhesive layer can extend to the entire metal layer 41b, or it can be arranged in a grid-like or multiple dot-like manner on the metal layer 41b.

[0102] <About the anti-dampening cable>

[0103] As described above, the flat wiring component 10 may also include a stripper wire 28 surrounded by the shielding component 40. The stripper wire 28 is a conductive path for grounding to the metal body of a vehicle or similar component. The grounding path may also be via a connector, in which case the insulating shrink tubing can be shortened, which is cost-effective. The stripper wire 28 is electrically connected to the shielding component 40.

[0104] In this embodiment, the stripper wire 28 is a bare stripper wire with the conductor core exposed. The stripper wire 28 can be made of the same material as the transmission line body 22 of the linear transmission component 20, or it can be made of a different material. However, the stripper wire 28 can cover the wire, or the covering layer can be partially removed. The stripper wire 28 can be a stranded wire made of multiple metal wires twisted together, or it can be a single wire.

[0105] The descrambling line 28 is arranged along the plurality of linear transmission components 20. The position of the descrambling line 28 is arbitrary; it can be located outside the parallel direction of the plurality of linear transmission components 20 or between the plurality of linear transmission components 20. If the descrambling line 28 is located outside the parallel direction of the plurality of linear transmission components 20, it is easier for the shielding component 40 to come into contact with the descrambling line 28.

[0106] The deflection line 28 can be located on the substrate 30 or outside the width direction of the substrate 30. If the deflection line 28 is located on the substrate 30, it is easy to keep the deflection line 28 in a parallel state relative to the multiple linear transmission components 20. If the deflection line 28 is located outside the width direction of the substrate 30, the shielding component 40 can be used to clamp the deflection line 28, which easily increases the contact area between the shielding component 40 and the deflection line 28.

[0107] The de-scratching line 28 may or may not be connected to the linear transmission component 20. If the de-scratching line 28 is far from the linear transmission component 20, the shielding component 40 can surround more of the area around the de-scratching line 28, easily increasing the contact area between the shielding component 40 and the de-scratching line 28. If the de-scratching line 28 is connected to the linear transmission component 20, when the shielding component 40 is pressed against the de-scratching line 28, the linear transmission component 20 can support the de-scratching line 28 from the opposite side, making it easier to press the shielding component 40 against the de-scratching line 28 with a stronger force, and the shielding component 40 is firmly adhered to the de-scratching line 28.

[0108] In this embodiment, the deflection line 28 is located on the fixing surface 31 of the substrate 30 on one side of the parallel direction of the plurality of linear transmission components 20. The outer surface of the deflection line 28 is metal, and the fixing surface of the substrate 30 is resin. The deflection line 28 is not fused to the substrate 30, and the deflection line 28 can be separated relative to the substrate 30.

[0109] When the first shielding sheet 42 and the second shielding sheet 46 of the shielding member 40 surround the substrate 30 and the plurality of linear transmission members 20, the overlapping side portion 44 and the overlapping target side portion 48 are overlapped on both outer sides of the substrate 30 through the adhesive layer 41c. Furthermore, between the overlapping portions of the overlapping side portion 44 and the overlapping target side portion 48 on both sides, the first shielding sheet 42 is bonded to the substrate 30, and the second shielding sheet 46 is bonded to the plurality of linear transmission members 20 on the opposite side of the substrate 30. It should be noted that the first shielding sheet 42 is bonded to the plurality of linear transmission members 20 between the dividing pieces 32.

[0110] The second shielding sheet 46 is held in a state covering the substrate 30 by being bonded to the first shielding sheet 42 and to the plurality of linear transmission members 20. Therefore, the second shielding sheet 46 is pressed against the deflection line 28 located on the substrate 30 and bonded to the deflection line 28 via the adhesive layer 41c. Thus, the deflection line 28 is held in position on the substrate 30 along the plurality of linear transmission members 20.

[0111] The adhesive layer 41c is disposed in the striped area relative to the metal layer 41b, so the metal layer 41b can contact and electrically connect with the stripping line 28 through the gaps in the adhesive layer 41c. In particular, since the striped area of ​​the adhesive layer 41c intersects with the stripping line 28, when viewed along the extension direction of the stripping line 28, exposed areas of the metal layer 41b appear at regular intervals in the gaps between the stripes of the adhesive layer 41c. Therefore, the stripping line 28 can contact the metal layer 41b more reliably. When the adhesive layer 41c is a conductive adhesive layer, the adhesive layer can be disposed across the entire surface, reducing the contact resistance between the metal part of the shielding member 40 and the stripping line, improving the shielding effect, and also increasing the adhesion.

[0112] Furthermore, the aforementioned flat wiring component 10 can also be held by other flat wiring components. These other flat wiring components can also be flat wiring components with a substrate that extends wider than the segment 32.

[0113] <Effects, etc.>

[0114] According to the flat wiring component 10 configured as described above, the overlapping side 44 and the overlapping object side 48 overlap in such a way that there is no substrate 30 between them, thus reducing the gap between the two connected metal layers 41b. Therefore, when the shielding component 40 surrounds the plurality of linear transmission components 20 fixed to the substrate 30, the gap at the joint of the shielding component 40 can be minimized, thereby improving electromagnetic shielding.

[0115] Alternatively, in cases involving multiple signal lines, each signal line can be individually covered with a tubular braided layer or shielding foil to create shielded wires. In this case, the processing cost of fusing the shielded wires to the substrate is higher than that of fusing ordinary wires to the substrate. Furthermore, the use of shielded wires may lead to larger-scale applications.

[0116] In this embodiment, the plurality of linear transmission components 20 fused to the substrate 30 are surrounded by the shielding component 40. Therefore, compared with the case of using shielded wires that shield multiple sets of signal lines individually, it is easier to achieve low cost and miniaturization. In addition, since the effects of fusion are difficult to affect the shielding component 40, stable shielding performance is easily obtained.

[0117] In fact, by using the absorption clamping method to evaluate the shielding performance in the frequency band of 9kHz to 1GHz, the results confirmed that a practically unobstructed shielding effect was achieved.

[0118] Furthermore, the shielding component 40 includes a first shielding sheet 42 and a second shielding sheet 46, wherein the overlapping sides 44 of the two sides of the first shielding sheet 42 and the overlapping target sides 48 of the two sides of the second shielding sheet 46 are maintained in a state of overlapping on the outer sides of the two sides of the substrate 30. Therefore, by overlapping the first shielding sheet 42 and the second shielding sheet 46, it is possible to easily surround a plurality of linear transmission components 20 and the substrate 30.

[0119] In addition, the substrate 30 includes a plurality of segmented pieces 32 that are arranged separately from each other along the extension direction of the plurality of linear transmission members 20, thus enabling the substrate 30 to be lightweight and also reducing material costs.

[0120] Furthermore, the flat cabling component 10 has bare stripper wires 28 surrounded by the shielding component 40, making it easy to ground the shielding component 40 through the bare stripper wires 28. Additionally, the amount of bare stripper wires 28 exposed from the shielding component 40 can be reduced.

[0121] Furthermore, the shielding member 40 is a laminated structure comprising a resin layer 41a and a metal layer 41b. Therefore, the resin layer 41a strengthens the shielding member 40, and the metal layer 41b insulates it from the outside. Additionally, the inner peripheral metal layer 41b can contact the bare stripped wire 28 to achieve conductivity. Moreover, since the bare stripped wire 28 can contact the shielding member 40 in more areas, the shielding member 40 can be reliably grounded via the stripped wire 28.

[0122] Furthermore, the shielding member 40 includes an adhesive layer 41c disposed on the inner peripheral side of the metal layer 41b, the adhesive layer 41c extending into a striped region intersecting with the bare stripe lines 28. Therefore, the shielding member 40 can be bonded to the substrate 30, the plurality of linear transmission members 20, and the bare stripe lines 28 via the adhesive layer 41c. Since the adhesive layer 41c intersects with the exposed stripe lines 28, it is easy for the exposed stripe lines 28 to come into contact with the metal layer 41b exposed between the adhesive layer 41c in the striped region. Additionally, the overlapping side 44 and the overlapping target side 48 are held in an overlapping state via the adhesive layer 41c. At this time, the striped region of the adhesive layer 41c intersects with respect to the extending directions of the overlapping side 44 and the overlapping target side 48, thus suppressing the gap between the overlapping side 44 and the overlapping target side 48, and further improving the shielding effect.

[0123] Furthermore, the shielding member 40 is bonded to the bare strip wire 28 via the adhesive layer 41c, which can hold the strip wire 28 in a state along the plurality of linear transmission members 20. Therefore, even if it is difficult to fix the bare strip wire 28 with exposed metal to the substrate 30, the shielding member 40 can hold the bare strip wire 28 in a state along the linear transmission members 20.

[0124] In addition, the bare stripping line 28 is held in position on the substrate 30 by the shielding member 40, so the stripping line 28 and the multiple linear transmission members 20 can be easily kept in a parallel state on the substrate 30.

[0125] [Implementation Method 2]

[0126] The flat wiring component 110 of Embodiment 2 will be described. Figure 5 This is a cross-sectional view of the flat wiring component 110. Figure 5 It is equivalent to Figure 3 A cross-sectional view. Furthermore, in the description of this embodiment, structural elements identical to those described in Embodiment 1 are labeled with the same reference numerals and their descriptions are omitted.

[0127] In Embodiment 1, an example was described where the shielding member 40 includes a first shielding plate 42 and a second shielding plate 46. The base member does not necessarily have to include both the first shielding plate 42 and the second shielding plate 46; as in this embodiment, the base member 140 may also include a single shielding plate 142.

[0128] The shielding sheet 142 is formed to have a width more than twice the width of the plurality of parallel linear transmission components 20. One side of the shielding sheet 142 is an overlapping side 144, and the other side is an overlapping object side 148.

[0129] Furthermore, the shielding sheet 142 surrounds the plurality of linear transmission components 20 and the substrate 30 in a manner that extends more than one circumference. For example, the substrate 30 is disposed in a region on one side of the shielding sheet 142 in the width direction, and the plurality of linear transmission components 20 are disposed thereon. The central portion of the shielding sheet 142 in the width direction is bent, and the region on the other side of the shielding sheet 142 in the width direction covers the plurality of linear transmission components 20 on the opposite side of the substrate 30.

[0130] The overlapping object side 148 extends from and bends from the side of the shielding sheet 142 on the side opposite to the curved portion at the center in the width direction of the shielding sheet 142, overlapping the outer side of the overlapping side 144. The adhesive layer 41c of the overlapping object side 148 is bonded to the resin layer 41a on the outer side of the overlapping side 144.

[0131] In addition, the adhesive layer 41c of the overlapping side 44 and the adhesive layer 41c of the overlapping object side 148 can also be bonded to each other at the position where they extend outward toward the shielding sheet 142.

[0132] The exposed stripping wires 28 are located on the substrate 30 on the outer side of the arrangement direction of the plurality of linear transmission components 20. The shielding sheet 142 is pressed against the stripping wires 28 and bonded via the adhesive layer 41c. In addition, the metal layer 41b exposed between the adhesive layers 41c contacts the exposed stripping wires 28, and the stripping wires 28 are electrically connected to the shielding sheet 142.

[0133] According to this embodiment, except for the difference in the number of substrate components, the same effect as in embodiment 1 can be obtained.

[0134] In addition, since multiple linear transmission components 20 and substrate 30 are surrounded by a single shielding sheet 142, the number of components used in manufacturing can be reduced.

[0135] [Variation Example]

[0136] Figure 6 This is a cross-sectional view of a modified flat wiring component 210. This figure is a cross-sectional view of the portion without a substrate.

[0137] In this modified example, the shielding member 240 corresponding to the shielding member 40 has an adhesive layer 241c instead of an adhesive layer 41c. The adhesive layer 241c is a conductive adhesive layer. For example, the adhesive layer 241c may also be an adhesive layer in which conductive fillers are mixed into the adhesive. The conductive filler may be a metal such as carbon or Ni. In this case, the adhesive layer 241c extends entirely, at least in the area covering the stripping line 28. The adhesive layer 241c may also extend entirely to the inner surface of the metal layer 41b. As a result, the contact resistance between the adhesive layer 241c and the stripping line 28 can be reduced, and the metal layer 41b is connected to the stripping line 28 with low resistance. As a result, the shielding effect of the metal layer 41b can be improved.

[0138] Furthermore, the adhesive layer 241c can be bonded to the deflection line 28 with the largest possible area. Therefore, the adhesive layer 241c can also be bent in a manner that depicts a partial cylindrical shape along the outline of the deflection line 28 and bonded to the deflection line 28.

[0139] The adhesive layers 241c on the two surfaces can be bonded to both sides of the runout line 28, such that the adhesive layers 241c are bonded to the runout line 28 with the largest possible area. For example, the second shielding sheet 46 can also be pressed into the first shielding sheet 42 on both sides of the runout line 28. In this case, the adhesive layers 241c can also be bonded to each other while the metal layer 41b covers more than half a circumference of the runout line 28.

[0140] To increase the contact area between the adhesive layer 241c and the deflection line 28, the deflection line 28 can be thickened. For example, the deflection line 28 can also be thicker than the linear transmission component 20.

[0141] In this modified example, the shielding component 240 can be bonded to the stripping line 28 via a conductive adhesive layer 241c. The conductive adhesive layer 241c can easily make contact with the stripping line 28 over a large area. Furthermore, the overlapping side 44 and the overlapping target side 48 are held in an overlapping state via the conductive adhesive layer 241c. Therefore, gaps between the overlapping side 44 and the overlapping target side 48 can be suppressed, further improving the shielding effect.

[0142] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other.
