1 / 36 “FLAT RIBBON TYPE CONDUCTIVE WIRE BODY AND FLAT RIBBON TYPE WIRE HARNESS TECHNICAL FIELD
[0001] The present invention relates to the technical field of electrical connections and, in particular, to a flat ribbon type conductor wire body and a flat ribbon type wire harness. FUNDAMENTALS
[0002] A power source and an electrical device in a vehicle are electrically connected by a wiring harness. Round wire is a technical solution commonly used by experts in the field today. With the gradual development of new energy vehicles, the functions of electrical devices in the vehicle are gradually increasing, and the available wiring space in the vehicle is decreasing. Meanwhile, as the power of the electrical devices used in new energy vehicles is much greater than that of traditional fuel vehicles, the problems of increased current carrying capacity, increased wire diameter, and increased electromagnetic interference from the wiring harness caused by the increased power are becoming increasingly prominent.Therefore, it became an urgent technical problem for those skilled in the art to find a technical solution that could fit into the vehicle's small wiring space and resolve the problem of electromagnetic interference generated by the wiring harness itself. SUMMARY
[0003] The present invention aims to provide a flat ribbon-type conductor wire body and a ribbon-type wire harness. Petition 870250084768, dated 09 / 19 / 2025, page 15 / 93 2 / 36 flat, which can adapt to the small wiring space in the vehicle and resolve the electromagnetic interference generated by the wiring harness itself. The flat ribbon-type wiring harness can be attached to a vehicle body and shaped according to the vehicle body's form. According to the skin effect principle, the cross-sectional area of the flat ribbon-type conductor wire body is smaller than that of a round wire with the same current-carrying capacity as the flat ribbon-type conductor wire body, so the flat ribbon-type conductor wire body requires less wiring space in the vehicle. Meanwhile, in the present invention, a shielding layer is inventively arranged outside an insulating layer of the flat ribbon-type conductor wire body, which can effectively resolve the electromagnetic interference in peripheral electrical devices generated by the flat ribbon-type conductor wire body when energized.Therefore, the technical solutions of the present invention can solve the problems of insufficient wiring space and electromagnetic interference in automobiles, especially new energy automobiles, to a certain extent.
[0004] The present invention provides a flat ribbon-type conductive wire body, including a conductive core body, an insulating layer, and a shielding layer. The insulating layer surrounds the conductive core body, and the shielding layer is disposed outside the insulating layer.
[0005] By providing the shielding layer, it is possible to make the body of the flat ribbon conductor wire have a good electromagnetic shielding function, a strong Petition 870250084768, dated 09 / 19 / 2025, p. 16 / 93 3 / 36 anti-electromagnetic interference capability and a low requirement for mounting space, and can be widely used in situations with high signal transmission stability requirements; meanwhile, it is possible to avoid the problems of large space occupied and high cost resulting from the use of large area shielding wires and satisfy the space requirement of the entire vehicle for the wiring harness layout.
[0006] In addition, the body of the flat ribbon-type conductor wire also includes a protective layer that surrounds the shielding layer. Furthermore, the shielding layer includes a shielding tape that is wrapped around the outer side of the insulating layer.
[0007] The shielding layer uses shielding tape that is wrapped around the outer side of the insulating layer, so that the shielding layer can be easily processed.
[0008] As an optional solution, the shielding tape is spirally wound with a defined overlap width on the insulating layer.
[0009] The shielding tape is wound in a spiral with a defined overlap width on the insulating layer, i.e., the shielding tape is wrapped densely around the insulating layer. Specifically, during winding, a portion of each turn of the shielding tape covers a previous turn of the shielding tape, with an overlap portion between them, and the width of the overlap portion is the overlap width. This winding method is simple and easy to operate, facilitates processing, and encloses the insulating layer. Petition 870250084768, dated 09 / 19 / 2025, page 17 / 93 4 / 36 and the conductor core body more completely without any exposed parts, thus obtaining a better shielding effect. As an optional solution, a plurality of shielding tapes can be alternately wrapped around the insulating layer, and specifically, the width of a position where the shielding tapes overlap and cross is the overlap width.
[0010] In addition, the defined overlap width is 1% to 95% of the width of the shielding tape.
[0011] For example, the adjusted overlap width is 5% to 50% of the width of the shielding tape.
[0012] The width of the overlapping portion can be from 1% to 95% of the width of the shielding tape. For example, the defined overlap width is from 5% to 50% of the width of the shielding tape, so that the shielding layer can enclose the insulating layer and the conductive core body more completely, and most of the conductive core bodies are enclosed by the shielding tape, thus further improving the electromagnetic shielding performance.
[0013] In addition, a shielding tape material includes an aluminum foil and / or a copper foil.
[0014] Aluminum foil and copper foil have light weights, high ductility, good electromagnetic shielding capabilities, low material cost, and low processing cost. As an optional solution, the shielding layer is made of one or more selected from the group consisting of a shielding metal and a composite material thereof, a shielding plastic, a shielding rubber, and shielding fabrics. Petition 870250084768, dated 09 / 19 / 2025, p. 18 / 93 5 / 36
[0015] In addition, the thickness of the shielding layer is from 0.001 mm to 27 mm.
[0016] The shielding layer with a thickness of 0.001 mm to 27 mm can ensure the shielding effect and can also prevent the assembly of the flat ribbon conductor body from being affected by an excessive bending radius. Furthermore, the shielding layer covers at least 7.8% of the surface area of the insulating layer, i.e., the shielding layer covers more than 7.8% of the surface area of the insulating layer. Additionally, the thickness of the gap between the insulating layer and the shielded layer is no greater than 157 mm, i.e., the thickness of the gap between the insulating layer and the shielded layer is less than or equal to 157 mm.
[0017] In addition, the insulating layer surrounds the conductive core body by means of one or more selected from the group consisting of an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a winding process and a weaving process.
[0018] In addition, the protective layer surrounds the shielding layer by means of one or more selected from the group consisting of an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a weaving process and a winding process.
[0019] In addition, a core body material Petition 870250084768, dated 09 / 19 / 2025, page 19 / 93 6 / 36 conductor is one or more selected from the group consisting of aluminum, aluminum alloy, copper, copper alloy, silver, and silver alloy.
[0020] Optionally, the conductor core body is a flat aluminum strip, which has the advantages of light weight, stable electrical connection performance, and low cost.
[0021] Moving on, the conductive core body material contains carbon or carbon-based compounds, such as graphite, carbon nanotubes, graphene, etc., which also possess excellent conductivity.
[0022] In addition, an insulating layer material is one or more selected from the group consisting of polyvinyl chloride, polyurethane, nylon, polypropylene, silicone rubber, cross-linked polyolefin, synthetic rubber, polyurethane elastomer, cross-linked polyethylene and polyethylene.
[0023] As an optional solution, the number of the conductor core body is one.
[0024] As an optional solution, the number of conductive central bodies is at least two, at least one of the conductive central bodies is externally enclosed by the insulating layer, and at least one insulating layer is enclosed by at least one shielding layer.
[0025] Specifically, the flat ribbon-type conductive wire body is a multi-core flat ribbon-type conductive wire body, which includes a protective layer, an insulating layer, and at least two conductive core bodies. Each of the protective layers, insulating layer, and conductive core body is flat in shape. At least one of the core bodies Petition 870250084768, dated 09 / 19 / 2025, page 20 / 93 7 / 36 conductors are externally wrapped by the insulating layer, and the protective layer is the outermost layer of the flat ribbon conductor wire body.
[0026] The flat ribbon-type conductive wire body includes at least two conductive core bodies. That is, a flat ribbon-type conductive wire body is integrated with a plurality of conductive core bodies, so as to obtain independent electrical connection of a plurality of paths, and a plurality of paths can be arranged by fixing a flat ribbon-type conductive wire body according to the present invention. On the one hand, it is possible to avoid the problem of low connection stability when a plurality of independent flat ribbon-type wire harnesses are connected to form a plurality of paths, thus avoiding the risk of falling after charging. On the other hand, a plurality of conductive core bodies are integrated into a conductive wire body, so that the structure is regular and compact and occupies less mounting space.On the other hand, the assembly process for multiple flat ribbon-type wire harnesses is streamlined, improving assembly efficiency and facilitating intelligent manufacturing. Furthermore, the flat ribbon conductor body not only allows for independent electrical connection of multiple paths but also achieves good electromagnetic shielding performance.
[0027] As an optional solution, the at least two conductive core bodies are arranged sequentially along a width direction of the conductive core body.
[0028] As an optional solution, at least two Petition 870250084768, dated 09 / 19 / 2025, p. 21 / 93 8 / 36 conductive core bodies are stacked along a thickness direction of the conductive core body.
[0029] As an optional solution, the plurality of conductive core bodies is arranged in both the width and thickness directions of the conductive core body.
[0030] Furthermore, the at least two central conducting bodies are arranged to be directly opposite each other in the same stacking direction.
[0031] The body of the flat ribbon conductor wire has a regular structure and is convenient to process and manufacture.
[0032] The body of the flat ribbon conductor wire not only allows independent electrical connection of a plurality of paths, but also achieves good electromagnetic shielding performance.
[0033] Furthermore, the plurality of insulating layers is formed integrally, so that the body of the flat tape type conductor wire is more stable and it is convenient to arrange the protective layer.
[0034] The present invention provides a flat ribbon-type wire harness, which includes a terminal and the body of the aforementioned flat ribbon-type conductor wire. The terminal is connected to one end of the conductive core body.

[0051] The technical solutions of the present invention will be described clearly and completely below with reference to the drawings. Obviously, the embodiments described are only a part, and not all, of the embodiments of the present invention. Petition 870250084768, dated 09 / 19 / 2025, p. 24 / 93 11 / 36 invention.
[0052] The components of the embodiments of the present invention generally described and illustrated in the drawings can be arranged and designed in several different configurations. Therefore, the following detailed description of the embodiments of the present invention represents only selected embodiments of the present invention and is not intended to limit the scope of the present invention.
[0053] All other embodiments derived by persons skilled in the art of the embodiments of the present invention without making inventive efforts shall fall within the scope of the present invention.
[0054] It should be noted that the flat ribbon-type conductor wire body according to the embodiments of the present invention can be used, but is not limited to, vehicles and can also be used in other devices and appliances that require electrical connections.
[0055] It should be noted that “a plurality of conductive core bodies 30”, that is, “at least two conductive core bodies 30” in the embodiments of the present invention means that the number of conductive core bodies 30 is two or more.
[0056] As illustrated in Figures 1, 3, 5 and 6 to 11, the present invention provides a flat ribbon-type conductor wire body, which includes a conductive core body 30, an insulating layer 20 and a shielding layer 40. The insulating layer 20 surrounds the conductive core body 30. The shielding layer 40 is disposed outside the insulating layer 20. By providing the shielding layer 40, it is possible to make it so that Petition 870250084768, dated 09 / 19 / 2025, p. 25 / 93 12 / 36 flat ribbon conductor wire body, according to the embodiments, has a good electromagnetic shielding function, a strong anti-electromagnetic interference capability, and a low mounting space requirement, and can be widely used in situations with high signal transmission stability requirements; meanwhile, it is possible to avoid the problems of large space occupied and high cost resulting from the use of large-area round shielding wires with a shielding function and satisfy the space requirement of the entire vehicle for the wiring harness layout.
[0057] It should be noted that a length and width of the insulating layer 2 0 and a length and width of the shielding layer 40 can be defined according to a length and width of the conductive core body 30.
[0058] The shielding layer 40 is arranged outside the insulation layer 20 to enclose the insulation layer 20 and thus enclose the conductive core body 30. The shielding layer 40 and the insulation layer 20 may be closely bonded to each other. Alternatively, there is a gap between the shielding layer 40 and the insulation layer 20. The relationship between the thickness of the gap between the shielding layer and the insulation layer (i.e., a vertical distance from a point on the insulation layer to the shielding layer) and the interference released from the flat ribbon-type conductive wire body is illustrated as follows in Table 1: Table 1 Petition 870250084768, dated 09 / 19 / 2025, p. 26 / 93 13 / 36 Distance between the insulating layer and the shielding layer: Parameter 0mm 7mm 17mm 27mm 37mm 4 7mm 57mm 67mm 7 7mm 87mm Interference released 5.2 dB 5.9 dB 6.3 dB 6.9 dB 7.5 dB 8.3 dB 9.8 dB 11.1 dB 13.2 dB 14.3 dB Distance between the insulating layer and the shielding layer: Parameter 97mm 107mm 117mm 127mm 137mm 14 7mm 157mm 167mm 177mm 187mm Interference released 15.2 dB 15.9 dB 16.4 dB 16.9 dB 17.7 dB 18.8 dB 19.6 dB 23.5 dB 30.6 dB 35.6 dB
[0059] As can be seen from the test results shown in Table 1, when the distance between the shielding layer 40 and the insulating layer 20 (the thickness of the gap between the shielding layer and the insulating layer) is 157 mm, the interference released from the flat tape-type conductive wire body is 19.6 dB, which is less than 20 dB; when the distance between the shielding layer 40 and the insulating layer 20 is greater than 157 mm, the interference released from the flat tape-type conductive wire body is greater than 20 dB. According to the introduction to shielding effectiveness in the relevant standards, the shielding level requirements can be met when the released interference is less than 20 dB. Therefore, the gap should not be greater than 157 mm to ensure the shielding effect.
[0060] Specifically, the flat ribbon conductor body further includes a protective layer 10 that surrounds the shielding layer 40. In this embodiment, the protective layer 10 is disposed outside the shielding layer 40, so as to protect the shielding layer and extend the service life of the flat ribbon conductor body.
[0061] Each of the protective layer 10, the insulating layer 20 and the conductive core body 30 can be of Petition 870250084768, dated 09 / 19 / 2025, p. 27 / 93 14 / 36 flat shape.
[0062] An insulating layer material 20 may be polycarbonate, polyvinyl chloride (PVC), polyurethane (PUR), nylon (PA), polypropylene (PP), TPU, silicone rubber (SIR), XLPE, TPU, TPV, PE, polysulfone, polytetrafluoroethylene, polyethylene, polyphenylene ether, polyester, PPS, phenolic resin, urea formaldehyde, DAP, TPE, XPE, XLPE, PFE, ETFE, TPR, TPE-O, perfluoroalkoxy alkane, TPE-S, PBT, EZM, styrene-acrylonitrile copolymer, ABS, polymethacrylate, EVA, polyphenylene sulfide, polystyrene, PBT, polyoxymethylene resin, natural rubber, styrene-butadiene rubber, nitrile butadiene rubber, cis-butadiene rubber, isoprene rubber, ethylene-propylene rubber, rubber of Chloroprene, butyl rubber, fluorinated rubber, polyurethane rubber, polyacrylate rubber, chlorosulfonated polyethylene rubber, epichlorohydrin rubber, chlorinated polyethylene rubber, chlorosulfurized rubber, butadiene rubber, hydrogenated nitrile rubber.polysulfide rubber, etc.
[0063] For example, the insulating layer material 20 is one or more selected from the group consisting of polyvinyl chloride (PVC), polyurethane (PUR), nylon (PA), polypropylene (PP), silicone rubber (SIR), cross-linked polyolefin (XLPO), synthetic rubber, polyurethane elastomer, cross-linked polyethylene (XLPE) and polyethylene (PE), for example, a combination of polypropylene and polyethylene, or a combination of polyvinyl chloride and polyethylene, etc.
[0064] A conductive core body material 30 can Petition 870250084768, dated 09 / 19 / 2025, page 28 / 93 15 / 36 being one or more selected from the group consisting of nickel, cadmium, zirconium, chromium, manganese, aluminum, tin, titanium, zinc, cobalt, gold, and silver, or their alloys. Alternatively, the conductive core body material may be aluminum-magnesium alloy, aluminum-lithium alloy, aluminum-manganese alloy, aluminum-zinc alloy, or aluminum-silicon alloy. Alternatively, the conductive core body material may contain carbon or carbon-based compounds, such as graphite, graphene, carbon nanotubes, and the like. Optionally, the conductive core body material may be one or more selected from the group consisting of aluminum, aluminum alloy, copper, copper alloy, silver, and silver alloy.
[0065] Based on the above embodiments, shielding layer 40 can be woven protecting metal parts (e.g., copper or aluminum) or a mixed fabric protecting metal and plastic parts (e.g., plastic parts such as ABS with a metal layer such as copper or aluminum on their outer side), or shielding layer 40 is a sheet structure, or shielding layer 40 is a structure in which a plurality of shielding tapes are crossed and overlapped, or shielding layer 40 is a layered structure formed by metal and plastic, such as a PET aluminum sheet.
[0066] The shielding layer may be formed from one or more selected from the group consisting of shielding metal and a composite material thereof, shielding plastic, shielding rubber, and shielding fabrics. Shielding plastic and shielding rubber are formed by adding Petition 870250084768, dated 09 / 19 / 2025, page 29 / 93 16 / 36 of a metallic material, such as copper or aluminum, or a material like graphene in a raw material during the production of plastics or rubber. The structure that forms the shielding fabrics has a part made of a shielding metal.
[0067] Optionally, as illustrated in Figures 12 and 13, in the embodiment, the shielding layer 40 includes a shielding tape 41 that is wound to wrap around an outer side of the insulation layer 20, so that the shielding layer 40 can be easily processed.
[0068] Shielding tape 41 can be wrapped in various ways, provided it can wrap around the insulating layer 20. For example, a plurality of turns of shielding tape 41 independent of each other are arranged along a length direction of the insulating layer 20. It can be understood that the shielding tape 41 has a plurality of sections. It may be possible to wrap one section of the shielding tape 41 in one position on an outer wall of the insulating layer 20 and then wrap another section of the shielding tape 41 in an adjacent position and then repeat the above operations until the entire conductive core body 30 wrapped with the insulating layer 20 is wrapped by the shielding tape 41.Optionally, each turn of the shielding tape 41 and the previous turn of the shielding tape 41 have an overlapping portion, so that the shielding layer 40 achieves a better wrapping effect on the insulating layer 20, and the body of the flat tape-type conductor wire achieves a better electromagnetic shielding effect.
[0069] As an optional solution, as illustrated in Figure 12, the shielding tape 41 is spirally wound with Petition 870250084768, dated 09 / 19 / 2025, page 30 / 93 17 / 36 a defined overlap width on the insulating layer 20, i.e., the shielding tape 41 is densely wound on the insulating layer 20. Specifically, during winding, a portion of each turn of the shielding tape 41 covers a previous turn of the shielding tape 41, with an overlapping portion 42 between them, and the width of the overlapping portion 42 is the overlapping width. A continuous section of shielding tape 41 can be wound on the insulating layer 20 without interruption. The winding method is simple and easy to operate, facilitates processing, and envelops the insulating layer 20 and the conductor core body 30 more completely without any exposed part, thus obtaining a better shielding effect.
[0070] The defined overlap width, i.e., the width of the overlap portion 42, can be from 1% to 95% of the width of the shielding tape 41. Table 2 shows the shielding effectiveness of the flat tape conductor body when the defined overlap width is from 0% to 5% of the width of the shielding tape 41. Table 3 shows the shielding effectiveness of the flat tape conductor body when the defined overlap width is from 0% to 100% of the width of the shielding tape 41. Details follow: Table 2 Percentage of overlap Parameter 0% 1% 2% 3% 4% 5% Shielding effectiveness 1 9.7 dB 2 5.9 dB 2 7.2 dB 2 8.4 dB 2 9.2 dB 4 4.3 dB Table 3 Overlap Percentage Parameter 0% 5% 15% 20% 25% 30% 35% 40% 45% 50% Petition 870250084768, dated 09 / 19 / 2025, page 31 / 93 18 / 36 Shielding Effectiveness 19.7 dB 44.3 dB 48.7 dB 53.6 dB 57.1 dB 60.9 dB 62.2 dB 65.3 dB 68.2 dB 7.21 dB Overlap Percentage Parameter 55% 60% 65% 70% 75% 80% 85% 90% 95% 100% Shielding Effectiveness 72.2 dB 72.2 dB 72.3 dB 72.6 dB 72.9 dB 73.2 dB 73.5 dB 73.6 dB 73.8 dB 73.8 dB
[0071] As can be seen from the test results shown in Tables 2 and 3, when the defined overlap width is greater than 1% of the width of the shielding tape 41, the shielding effectiveness is greater than 20dB, which meets the requirements of the relevant standards; when the defined overlap width is greater than 95%, the shielding effectiveness is almost unchanged. In order to save the amount of shielding tape used, the range of the defined overlap width is limited to 1% to 95%. As can be seen from the data above, when the adjusted overlap width is 5% of the width of the shielding tape 41, the shielding effectiveness is obviously improved; when the percentage of the defined overlap width reaches 50%, the shielding effectiveness can reach 72.1 dB; and when the percentage of the defined overlap width exceeds 50%, the test data obviously does not change.In order to reduce the amount of shielding tape used, it is recommended that the defined overlap width, i.e., the width of the overlap portion 42, be exemplarily from 5% to 50% of the width of the shielding tape 41.
[0072] As illustrated in Figure 12, the material of the shielding tape 41 can be a material with electromagnetic shielding function, such as a PET aluminum foil.
[0073] As an optional solution, the tape material of Petition 870250084768, dated 09 / 19 / 2025, page 32 / 93 19 / 36 Shielding 41 includes an aluminum foil and / or a copper foil. That is, shielding tape 41 may be an aluminum foil tape that is wrapped around the insulating layer 20 to form an aluminum foil shielding layer. Shielding tape 41 may also be a copper foil tape that is wrapped around the insulating layer 20 to form a copper foil shielding layer. In this case, if shielding tape 41 is densely wrapped, a continuous section of aluminum foil tape or copper foil tape may be wrapped around the insulating layer 20. Alternatively, shielding tape 41 includes both aluminum foil tape and copper foil tape.For example, as illustrated in Figure 13, shielding tape 41 is spliced by a section of aluminum foil tape 411 and a section of copper foil tape 412 to form a spliced or overlapping structure, and the aluminum foil tape 411 and the copper foil tape 412 have overlapping parts in the splice or overlapping position. In this case, if shielding tape 41 is tightly wound, the spliced or overlapping structure may wrap around the insulating layer 20.For another example, a plurality of 40 shielding layers are arranged sequentially from the inside out, that is, a 40 shielding layer surrounds the previous 40 shielding layer, in which at least one 40 shielding layer is an aluminum foil shielding layer formed by winding an aluminum foil tape and another 40 shielding layer is a copper foil shielding layer formed by winding a copper foil tape; or an aluminum foil shielding layer and a copper foil shielding layer are arranged. Petition 870250084768, dated 09 / 19 / 2025, page 33 / 93 20 / 36 alternately.
[0074] In embodiment, aluminum foil and copper foil generally have light weights, high ductility, good electromagnetic shielding capabilities, low material cost, and low processing cost. Comparatively, aluminum foil is lighter than copper foil, and copper foil has better shielding capabilities than aluminum foil. Aluminum foil or copper foil can be selected as needed. However, the scope of protection of the present invention is not limited to copper foil or aluminum foil, and any other shielding material is also possible.
[0075] Based on the above embodiments, the thickness of the shielding layer 40 can be adjusted according to specific conditions. For example, considering the influences of the shielding layer thickness on electromagnetic interference (EMI), radio frequency interference (FRI), and the bending radius of the flat ribbon conductor body comprehensively, it is possible to select an appropriate shielding layer thickness. A relationship between the shielding layer thickness and EMI, a relationship between the shielding layer thickness and FRI, and a relationship between the shielding layer thickness and an increment of the bending radius of the flat ribbon conductor body are shown below in Table 4. Table 4 Petition 870250084768, dated 09 / 19 / 2025, page 34 / 93 21 / 36 Shielding Layer Thickness Parameter 0.001 mm 0.05 mm 1 mm 3 mm 5 mm 7 mm 9 mm 11 mm 13 mm 15 mm Anti-E MI 2.1 dB 4.3 dB 5.4 dB 19.3 dB 27.6 dB 38.4 dB 45.5 dB 58.4 dB 68.5 dB 85.1 dB Anti-F RI 1.4 dB 2.6 dB 3.2 dB 14.4 dB 25.3 dB 35.2 dB 48.8 dB 67.7 dB 77.3 dB 88.1 dB Anti-Bending Radius Increment 1 mm 2 mm 4 mm 5 mm 6 mm 8 mm 9 mm 10 mm 12 mm 15.5 mm Shielding Layer Thickness Parameter 17mm 19mm 21mm 2.3mm 2.5mm 27mm 2.9mm 31mm 33mm 35mm Anti-E MI 96.4dB 104.2dB 113.3dB 116.6dB 117.9dB 119.6dB 120.6dB 120.6dB 120.8dB 120.9dB Anti-F RI 98.4dB 105.4dB 116.2dB 118.3dB 119.1dB 121.4dB 120.5dB 120.6dB 120.7dB 120.8dB Anti-bending radius increment 2.4mm 5.9mm 95mm 135mm 17.8mm 18.9mm 2.31mm 2.4.6mm 2.6.9mm 2.81mm
[0076] As can be seen from the test results shown in Table 4, when the thickness of shielding layer 40 is between 0.001 mm and 27 mm, the shielding effect of the flat ribbon conductor wire body, i.e., anti-electromagnetic interference (EMI) and anti-radio frequency interference (FRI), will be improved with increasing thickness, but when the thickness of shielding layer 40 exceeds 27 mm, the shielding capacity of the flat ribbon conductor wire body changes only slightly without obvious improvement; when the thickness of shielding layer 40 is between 0.001 mm and 27 mm, the increment of the bending radius of the flat ribbon conductor wire body increases with increasing thickness, but when the thickness of shielding layer 40 exceeds 27 mm, the increment of the radius Petition 870250084768, dated 09 / 19 / 2025, p. 35 / 93 The curvature of the 22 / 36 flat ribbon conductor wire exceeds 200 mm, which is not conducive to practical processing. Therefore, the shielding layer thickness is typically between 0.001 mm and 27 mm.
[0077] Based on the above embodiments, the surface area of the insulating layer covered by the shielding layer can be adjusted as needed. Table 5 shows the shielding effectiveness of the flat tape conductor body when the shielding layer covers 0.8% to 7.8% of the insulating layer surface area. Table 6 shows the shielding effectiveness of the flat tape conductor body when the shielding layer covers 0.8% to 100% of the insulating layer surface area. Table 5 "X. Area covered by insulating layer Parameter x". 0.80% 1.80% 2.80% 3.80% 4.80% 5.80% 6.80% 7.80% Shielding effectiveness 5.2 dB 6.8 dB 7.9 dB 12.6 dB 14.8 dB 16.5 dB 18.2 dB 20.2 dB Table 6 X*..

[0078] As can be seen from the test results shown in Tables 5 and 6, when the surface area of the insulating layer covered by the shielding layer is less than 7.8%, the shielding effectiveness of the conductor wire body is reduced. Petition 870250084768, dated 09 / 19 / 2025, page 36 / 93 23 / 36 flat tape type is less than 20 dB, which does not meet the relevant usage requirements, and when the surface area of the insulating layer covered by the shielding layer is greater than or equal to 7.8%, the shielding effectiveness is relatively good. Therefore, the shielding layer covers at least 7.8% of the surface area of the insulating layer.
[0079] Furthermore, based on any of the above technical solutions, the insulating layer 20 can be made of plastic, rubber, or similar materials. The insulating layer 20 can be formed by one or more selected from the group consisting of an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a winding process, and a weaving process. The insulating layer 20 formed by the above processes has sufficient strength, good stability, and high production efficiency.
[0080] The winding process means that a strip with insulating and adhesive material is wound around the body of the conductor wire in several layers to form a compact, staggered structure, so that a closed insulating environment is formed due to the viscosity of the insulating and adhesive material.
[0081] The weaving process means that a strip with insulating and adhesive material is woven and wound onto the outside of the conductor wire body in several layers to form a compact, staggered structure, so that a closed insulating environment is formed due to the viscosity of the insulating and adhesive material.
[0082] The extrusion process means a method of Petition 870250084768, dated 09 / 19 / 2025, page 37 / 93 24 / 36 processing in which, under the action between a barrel and a screw of an extrusion machine, a material is heated and plasticized while being pushed by the screw and then continuously passes through an extrusion machine head and a mold with a corresponding shape, so as to be manufactured into various cross-sectional products or semi-finished products.
[0083] The injection molding process means that molten raw material is pressurized, injected, cooled and separated by an injection molding machine, so as to be transformed into finished products with a specific shape in a mold with a corresponding shape.
[0084] The spraying process is a molding process in which a material is sprayed directly onto the surface of an object to be processed or into a cavity, and is subsequently solidified and molded.
[0085] The dip molding process is a plastic coating process that can be classified into two types, namely powder dip and liquid dip, according to the raw material of the dip. Powder dip is frequently used to coat metallic surfaces, which have the characteristics of the firm and hard bond of the powder coating. The liquid dip process mainly uses hot dip liquid. A thermoplastic coated film has the characteristic of being softened after being heated and cured into a film after being cooled, which is mainly a physical fusion and plasticization process, and the processing and production are simple. The liquid dip coating is thick and soft and Petition 870250084768, dated 09 / 19 / 2025, page 38 / 93 25 / 36 can serve as a protective product regardless of the mold.
[0086] Slush molding is also called coating coagulation molding and is an important method for manufacturing hollow soft products with paste plastics. The advantages of slush molding are low equipment cost, high production speed and simple process control, but the thickness and weight accuracies of the products are poor.
[0087] The electrophoresis process is a technological method in which a water-soluble organic coating with electrical charges is uniformly dissolved in a solution, a metallic material or a workpiece to be processed is taken as an anode or a cathode, and current is applied so that the organic coating is adhered to the workpiece to be processed and then dried and solidified to obtain finished products.
[0088] The protective layer 10 can be made of an insulating material, such as plastic, rubber, etc. The protective layer 10 can have both protective and insulating functions, thus improving the stability of the flat tape-type conductor wire body. The protective layer 10 can be formed by one or more selected from the group consisting of an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a winding process, and a weaving process. The protective layer 10 formed by the above processes has sufficient strength, good stability, and high Petition 870250084768, dated 09 / 19 / 2025, page 39 / 93 26 / 36 production efficiency.
[0089] The protective layer 10 may have various structural forms. For example, the protective layer 10 includes a plurality of protective layer segments arranged at intervals along a length direction of the conductive core body 30. Optionally, the protective layer 10 is arranged integrally outside the insulating layer 20 to facilitate processing.
[0090] It should be noted that the insulating layer 20 and / or the protective layer 10 can be formed by one or more selected from the group consisting of an extrusion process, an injection molding process, a spraying process, a dip molding process, an electrophoresis process, a winding process and a weaving process. The insulating layer 20 or the protective layer 10 formed by the above processes has sufficient strength, good stability and high production efficiency.
[0091] There may be one or more conductive core bodies, which will be described in detail with the following examples.
[0092] Implementation 1
[0093] Based on any of the above embodiments, there is a conductive core body in the flat ribbon-type conductive wire body according to that embodiment. Specifically, as illustrated in Figure 1, the flat ribbon-type conductive wire body according to this embodiment includes a conductive core body 30, an insulating layer 20, a shielding layer 40, and a protective layer 10. There is a conductive core body 30 and, Petition 870250084768, dated 09 / 19 / 2025, p. 40 / 93 27 / 36 correspondingly, there is an insulating layer 20. The insulating layer 20 surrounds the conductive core body 30, the shielding layer 40 surrounds the insulating layer 20, and the shielding layer 10 surrounds the shielding layer 40. Each of the protective layer 10, the insulating layer 20, and the conductive core body 30 can be of a flat shape.
[0094] By providing the 40 shielding layer, it is possible to make the body of the flat ribbon conductor wire according to this embodiment have a good electromagnetic shielding function, a strong anti-electromagnetic interference capability and a low requirement for mounting space and can be widely used in occasions with high demand for signal transmission stability; meanwhile, it is possible to avoid the problems of large space occupied and high cost resulting from the use of large area shielding wires with a shielding function and satisfy the space requirement of the whole vehicle for the wiring harness layout.
[0095] implementation 2
[0096] Based on any of the above embodiments, there are at least two conductive core bodies in the flat ribbon-type conductor wire body according to this embodiment. Specifically, as illustrated in Figures 2 to 11, the flat ribbon-type conductor wire body according to this embodiment includes a protective layer 10, an insulating layer 20, a shielding layer 40, and at least two conductive core bodies 30. Each of the protective layers 10, the insulating layer 20, and the conductive core body 30 is flat in shape. At least one body of Petition 870250084768, dated 09 / 19 / 2025, page 41 / 93 28 / 36 conductive core 30 is externally surrounded by insulating layer 20, and at least one insulating layer 20 is surrounded by at least one shielding layer 40. The shielding layer 10 is the outermost layer of the flat ribbon-type conductive wire body.
[0097] In this embodiment, the flat ribbon-type conductor body includes at least two 30 conductive core bodies, i.e., one flat ribbon-type conductor body is integrated into a plurality of 30 conductive core bodies, so as to obtain independent electrical connection of a plurality of paths, and a plurality of paths can be arranged by fixing a flat ribbon-type conductor body according to this embodiment. On the one hand, it is possible to avoid the problem of low connection stability when a plurality of independent flat ribbon-type wire harnesses are connected to form a plurality of paths, thus avoiding the risk of falling after loading. On the other hand, a plurality of 30 conductive core bodies are integrated into one conductor body, so that the structure is regular and compact and occupies less mounting space.On the other hand, the assembly process for multiple flat ribbon-type wire harnesses is streamlined, making assembly convenient, assembly efficiency high, and intelligent manufacturing easier. Furthermore, by providing a 40mm shielding layer outside the 20mm insulating layer, the flat ribbon-type conductor wire body can have good electromagnetic shielding, strong anti-electromagnetic interference capability, and low risk. Petition 870250084768, dated 09 / 19 / 2025, page 42 / 93 29 / 36 mounting space requirement, and can be widely used in situations with high signal transmission stability requirements; meanwhile, it is possible to avoid the problems of large space occupied and high cost resulting from the use of large-area shielding wires with a shielding function and satisfy the space requirement of the entire vehicle for the wiring harness layout. The flat ribbon-type conductor wire body according to this embodiment not only achieves a multipath arrangement but also achieves an electromagnetic shielding function.
[0098] The number of at least two central conducting bodies 30 can be two, three, four, five, etc., which can be adjusted as needed.
[0099] As illustrated in Figure 3, only one or some of the plurality of conductive core bodies 30 may be externally enclosed by the insulating layer 20, and other conductive core bodies 30 not enclosed by the insulating layer 20 are in direct contact with the protective layer 10, which may serve as the insulating layer thereof. Optionally, as illustrated in Figure 5, each of the conductive core bodies 30 is externally enclosed by the insulating layer 20, which achieves better insulating performance and facilitates processing. Optionally, as illustrated in Figures 4 to 11, each of the conductive core bodies 30 is externally enclosed by the insulating layer 20, which achieves better insulating performance and facilitates processing.
[0100] The specifications for the plurality of 30 central conducting bodies may differ. Some bodies Petition 870250084768, dated 09 / 19 / 2025, page 43 / 93 30 / 36 conductive core 30 bodies may have the same specification, and some conductive core 30 bodies may have different specifications. Optionally, the plurality of conductive core 30 bodies may have the same specification, that is, the sizes of the plurality of conductive core 30 bodies are the same, and the structures of the plurality of conductive core 30 bodies are the same, in order to facilitate processing.
[0101] The plurality of insulating layers 20 can be arranged in various ways. For example, the independent insulating layers 20 can be formed correspondingly by separately performing an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a winding process or a weaving process off each of the conductive core bodies 30. Optionally, the integral insulating layer 20 can be formed by simultaneously performing an extrusion process, an injection molding process, a spraying process, a dip molding process, a slush molding process, an electrophoresis process, a winding process or a weaving process off the plurality of conductive core bodies 30, i.e. the plurality of insulating layers 20 are formed integrally.In this way, the body of the flat ribbon-type conductor wire is more stable and the arrangement of the protective layer 10 is more convenient.
[0102] Furthermore, based on the above concretizations, the plurality of central conducting bodies 30 can be Petition 870250084768, dated 09 / 19 / 2025, p. 44 / 93 31 / 36 arranged in various ways. For example, the plurality of 30 central conducting bodies is arranged sequentially along the width direction of the same, which can also be understood as the plurality of 30 central conducting bodies being in a left-right arrangement.
[0103] The positions of the plurality of conductive central bodies 30 may be different in the direction of their thickness. For example, there are two conductive central bodies 30 arranged to be completely staggered; or, as illustrated in Figure 2, one conductive core body 30 and the other conductive core body 30 are partially overlapping. Alternatively, some conductive core bodies 30 may have the same position and other conductive core bodies 30 may have different positions in the direction of their thickness. For example, there are three conductive central bodies 30, two of which have the same position and the other has a different position from those of the two conductive central bodies 30 above.
[0104] As an optional solution, as illustrated in Figures 3 and 4, the plurality of conductive core bodies 30 are arranged to be directly opposite each other in the direction of their width, that is, the positions of the plurality of conductive core bodies 30 are consistent in the direction of their thickness. It can also be understood that a side perpendicular to the width direction of the conductive core body is a first side, and the first sides of two adjacent conductive core bodies are arranged face to face, so that the flat ribbon-type conductive wire body has a regular structure and is Petition 870250084768, dated 09 / 19 / 2025, p. 45 / 93 32 / 36 convenient to be processed and manufactured.
[0105] For another example, the plurality of central conducting bodies 30 can also be arranged in such a way that at least two central conducting bodies 30 are stacked along the thickness direction of the same, which can also be understood as the plurality of central conducting bodies 30 being in a top-down arrangement.
[0106] The positions of the plurality of conductive central bodies 30 may be different in the direction of their width. For example, there are two conductive central bodies 30 arranged to be completely staggered; or, as illustrated in Figure 7, one conductive core body 30 and the other conductive core body 30 are partially overlapping. Alternatively, some conductive core bodies 30 may have the same position and other conductive core bodies 30 may have different positions in the direction of their width. For example, there are three conductive central bodies 30, two of which have the same position and the other has a different position from those of the two conductive central bodies 30 above.
[0107] As an optional solution, as illustrated in Figures 8 to 10, the plurality of conductive core bodies 30 are arranged to be directly opposite each other in the direction of their thickness, that is, the positions of the plurality of conductive core bodies 30 are consistent in the direction of their width. It can also be understood that a side perpendicular to the direction of the thickness of the conductive core body is a second side, and the second sides of two conductive core bodies Petition 870250084768, dated 09 / 19 / 2025, p. 46 / 93 33 / 36 adjacent conductors are arranged face to face, so that the body of the flat ribbon conductor wire has a regular structure and is convenient to process and manufacture.
[0108] For another example, the plurality of conductive core bodies 30 can also be arranged as follows: as illustrated in Figure 11, a plurality of conductive core bodies 30 are arranged both in the direction of their width and in the direction of their thickness, that is, the plurality of conductive core bodies 30 are stacked both in the direction of their thickness and in the direction of their width. The arrangement of the plurality of conductive core bodies 30 according to this embodiment is suitable for the case where there are at least three conductive core bodies 30.
[0109] As illustrated in Figures 5, 10, and 11, when a plurality of insulating layers 20 are arranged independently of each other, a shielding layer 40 encloses at least one insulating layer 20. For example, the number of shielding layers 40 is the same as the number of insulating layers 20, both being plural, and the shielding layers 40 enclose the insulating layers 20 in a one-to-one correspondence; or, the number of shielding layers 40 is greater than one, and is less than the number of insulating layers 20, and at least one shielding layer 40 encloses a plurality of insulating layers 20; or, a shielding layer 40 simultaneously encloses a plurality of insulating layers 20. When a plurality of insulating layers 20 is integrally formed, the shielding layer 40 can directly enclose the outer walls of the Petition 870250084768, dated 09 / 19 / 2025, p. 47 / 93 34 / 36 plurality of insulating layers 20.
[0110] It does not matter whether a plurality of insulating layers 20 are arranged independently of each other or formed integrally, an insulating layer 20 is externally surrounded by at least one shielding layer 40, that is, the number of shielding layer(s) 40 can be one, two, three, four, etc. The insulating layer 20 can be externally surrounded by a plurality of shielding layers 40 in series from the inside out.
[0111] It should be noted that the flat ribbon-type conductor wire body according to the embodiments of the present invention may need to be bent in practical applications and may be bent in the same plane, which can be understood as the bending portion of the flat ribbon-type conductor wire body and the wire body portions of the flat ribbon-type conductor wire body on both sides of the bending portion are located in the same plane. Alternatively, the wire body portion on one side of the bending portion is located in one plane, and the wire body portion on the other side of the bending portion is located in another plane. For example, the flat ribbon-type conductor wire body is bent to form an acute angle, an obtuse angle, or a right angle, etc.
[0112] In practical applications, the flat ribbon-type conductor wire body according to the embodiments of the present invention may be ungrounded, i.e., the shielding layer may be ungrounded. Alternatively, the shielding layer of the flat ribbon-type conductor wire body according to the embodiments of the present invention may be Petition 870250084768, dated 09 / 19 / 2025, page 48 / 93 35 / 36 at least partially grounded. Table 7 below shows the influences of the two cases on antimagnetic field interference capability, antiradio interference capability, electromagnetic interference capability, and safety capability. Table 7 X. Capacity X. Technical Status of Yamada Shielding X. Antimagnetic Field Interference Capacity Anti-Radio Interference Capacity Electromagnetic Interference Capacity Safety Capacity The shielding layer is not grounded Having a risk of electromagnetic interference Having a risk of radio frequency interference Having electromagnetic interference in other components The cable core is damaged and the leaked current can burn the insulating layer The shielding layer is at least partially grounded Obviously improving the anti-electromagnetic interference capacity of the flat tape Obviously improving the anti-radio interference capacity of the flat tape The added shielding layer can protect the electromagnetic field generated in the cable If the cable core is damaged, the leaked current can flow to a grounding grid along the shielding layer, which achieves safety protection
[0113] In addition, based on any of the above embodiments, the present invention further provides a flat ribbon-type wire harness, which includes a terminal and the body of the flat ribbon-type conductor wire according to any of the above technical solutions. The terminal is connected to one end of the body of the flat ribbon-type conductor wire.

[0115] Finally, it should be noted that the above embodiments are used only to illustrate, rather than limit, the technical solutions of the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified or some or all of the technical features may be equivalently substituted, without causing the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of various embodiments of the present invention.
