Technical Field

[0001] This utility model relates to the field of data transmission cable technology, specifically to a high-strength, ultra-low-loss data transmission cable. Background Technology

[0002] Currently, ordinary data transmission cables on the market generally do not have good tensile strength and have low tensile strength. When subjected to external force, the external force acts directly on the cable core, causing the conductor or insulation of the cable to deform and break, making the cable unable to work. In addition, their flame retardant and fire-resistant properties are relatively poor, and their safety cannot be guaranteed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a high-strength, ultra-low-loss data transmission cable, solving the problems raised in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A high-strength, ultra-low-loss data transmission cable includes several cable cores. Each cable core includes a conductor, the outer wall of which is covered with an insulation layer. The outer wall of the insulation layer is covered with a moisture-proof layer. The outer wall of the moisture-proof layer is covered with an inner tensile-strength wrapping layer. The outer wall of each cable core is covered with four metal layers, which are evenly distributed around a central tensile-strength core material. A microporous core is provided between every two metal layers. The outer wall of each metal layer is covered with a shielding layer. A filler layer is provided between the metal layers, the microporous core, and the shielding layer. The outer wall of the shielding layer is covered with an oxygen-barrier fireproof layer. The outer wall of the oxygen-barrier fireproof layer is covered with a flame-retardant layer. The outer wall of the flame-retardant layer is covered with a buffer layer. The outer wall of the buffer layer is covered with a foamed armor layer. The outer wall of the foamed armor layer is covered with an outer sheath.

[0005] Preferably, the cross-section of the buffer layer is configured as a corrugated structure, a plurality of first tensile cores are provided between the flame retardant layer and the buffer layer, and a plurality of second tensile cores are provided between the buffer layer and the foamed armor layer.

[0006] Preferably, the moisture-proof layer is made of non-woven fabric tape, the inner tensile wrapping layer is woven from aramid fibers, and the metal layer is made of aluminum foil.

[0007] Preferably, the central tensile-strength core material is a core structure formed by twisting aramid fiber bundles and stainless steel wires, and the outer wall of the central tensile-strength core material is covered with a friction-reducing layer, which is made of polytetrafluoroethylene material.

[0008] Preferably, the filler layer is made of powdered magnesium oxide material.

[0009] Preferably, the shielding layer adopts a structure in which tin-plated copper wire and aluminum-magnesium wire are spirally wound in opposite directions.

[0010] Preferably, the oxygen-barrier fireproof layer is made of aluminum hydroxide, and the flame-retardant layer is made of ceramicized silicone rubber.

[0011] Preferably, the foamed armor layer is formed by twisting multiple foamed armor cores concentrically, and the foamed armor cores are made of modified polypropylene foam material.

[0012] Preferably, the outer sheath is made of flame-retardant thermoplastic polyurethane elastomer sheath material.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model provides a high-strength, ultra-low-loss data transmission cable with a cable core. The cable core consists of a conductor and, sequentially from the inside out, an insulation layer, a moisture-proof layer, and an inner tensile-resistant wrapping layer. The moisture-proof layer is made of non-woven fabric tape, which is moisture-proof, breathable, flexible, lightweight, non-flammable, non-toxic, non-irritating, and inexpensive, thus improving the moisture-proof performance of the cable core. The inner tensile-resistant wrapping layer is woven from aramid fibers, significantly improving the tensile strength of the cable core and ensuring its resistance to external tensile forces. It is not easily damaged or broken because it has a metal layer made of aluminum foil to prevent signal interference between cable cores. It also features a central tensile-strength reinforced core, a core structure formed by stranding aramid fiber bundles and stainless steel wire, which has high tensile strength and excellent tensile properties. In terms of lateral pressure resistance, it can alleviate the load stress applied to the cable core to a certain extent, reducing local stress concentration and preventing core breakage. Furthermore, it incorporates friction-reducing... The first layer is made of polytetrafluoroethylene (PTFE), and the friction-reducing layer provides excellent sliding properties, allowing sliding between the inner and outer layers of the cable core, creating an effect similar to a rolling bearing. This reduces sliding friction resistance, improves bending resistance, helps suppress wire and core breakage, enhances durability, and reduces safety hazards. A filler layer made of powdered magnesium oxide provides flame retardancy and heat insulation for the data transmission cable. Since powdered magnesium oxide is non-combustible, it isolates the flame from the metal layer in case of combustion on the outer layer, ensuring normal operation of the cable core. The microporous core filler further stabilizes the cable core structure and ensures a more uniform dielectric constant, guaranteeing stable and consistent data transmission performance. A shielding layer using tinned copper wire and aluminum-magnesium wire in a reverse spiral braiding structure replaces the original single copper or aluminum wire braiding structure. The tinned copper wire offers high rigidity and better conductivity, balancing flexibility and rigidity to significantly improve the data transmission cable's anti-interference capabilities. This invention features an oxygen-barrier fireproof layer made of aluminum hydroxide, which significantly improves the fire resistance and flame retardancy of the data transmission cable. Aluminum hydroxide undergoes an endothermic decomposition reaction during combustion, absorbing a large amount of heat from the surrounding air and lowering the temperature of the burning data transmission cable surface. The generated water molecules also absorb a significant amount of heat from the cable surface, and the resulting metal oxide crust prevents further contact between oxygen and organic matter. Furthermore, a flame-retardant layer made of ceramicized silicone rubber rapidly forms a hard, dense ceramic-like shell at high temperatures. This shell does not melt or drip in a fire environment, effectively isolating flames and preventing the spread of fire. During combustion, the ceramicized silicone rubber produces very little smoke and is non-toxic and harmless. This invention features a buffer layer encased on the outer wall of a flame-retardant layer, and a foamed armor layer encased on the outer wall of the buffer layer. The buffer layer has a corrugated cross-section. Several first tensile cores are provided between the flame-retardant layer and the buffer layer. The first tensile cores not only further increase the tensile strength of the data transmission cable but also prevent the buffer layer from damaging the flame-retardant layer. Several second tensile cores are provided between the buffer layer and the foamed armor layer. The second tensile cores not only further increase the tensile strength of the data transmission cable but also prevent the buffer layer from damaging the foamed armor layer. This invention features a foamed armor layer, constructed from multiple concentrically twisted foamed armor cores made of modified polypropylene foam material. This foamed armor layer replaces the traditional metal armor layer, significantly reducing the weight of the data transmission cable. It absorbs external impact energy through its own deformation, effectively protecting the cable from damage. Furthermore, the outer sheath, made of flame-retardant thermoplastic polyurethane elastomer, boasts tensile strength and abrasion resistance far exceeding other sheath materials. Its tear resistance, low-temperature flexural strength, oil resistance, and aging resistance are also outstanding, further extending the service life of the data transmission cable.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a high-strength, ultra-low-loss data transmission cable is provided.

[0021] Example 1: As shown in the attached diagram of the instruction manual. Figure 1 As shown, a high-strength, ultra-low-loss data transmission cable includes several cable cores 1. Each cable core 1 includes a conductor 1.1. The outer wall of the conductor 1.1 is covered with an insulation layer 1.2. The outer wall of the insulation layer 1.2 is covered with a moisture-proof layer 1.3. The outer wall of the moisture-proof layer 1.3 is covered with an inner tensile-strength wrapping layer 1.4. The outer wall of each cable core 1 is covered with four metal layers 2, which are evenly distributed around a central tensile-strength core material 3. A microporous core 5 is provided between every two metal layers 2. The outer wall of the metal layer 2 is covered with a shielding layer 6. A filling layer 4 is filled between the metal layer 2, the microporous core 5 and the shielding layer 6. The outer wall of the shielding layer 6 is covered with an oxygen-barrier fireproof layer 7. The outer wall of the oxygen-barrier fireproof layer 7 is covered with a flame-retardant layer 8. The outer wall of the flame-retardant layer 8 is covered with a buffer layer 10. The outer wall of the buffer layer 10 is covered with a foamed armor layer 12. The outer wall of the foamed armor layer 12 is covered with an outer sheath 13.

[0022] Example 2: As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a high-strength, ultra-low-loss data transmission cable includes a cable core 1, which consists of a conductor 1.1 and, sequentially from the inside out, an insulation layer 1.2, a moisture-proof layer 1.3, and an inner tensile-resistant wrapping layer 1.4 covering the conductor 1.1. The moisture-proof layer 1.3 is made of non-woven fabric, which is moisture-proof, breathable, flexible, lightweight, non-flammable, non-toxic, non-irritating, and inexpensive, thus improving the moisture-proof performance of the cable core 1. The inner tensile-resistant wrapping layer 1.4 is woven from aramid fibers, significantly improving the tensile strength of the cable core 1 and ensuring that it is not easily damaged or broken under external tensile forces. A metal layer 2, made of aluminum foil, is included to prevent signal interference between the cable cores 1. The cable incorporates a central tensile-strength reinforced core 3, which is a core structure formed by twisting aramid fiber bundles and stainless steel wires. This core possesses high tensile strength and excellent tensile properties. In terms of lateral pressure resistance, it can alleviate the load stress applied to the cable core 1 to a certain extent, reducing local stress concentration and preventing core breakage. A friction-reducing layer 3.1, made of polytetrafluoroethylene (PTFE), provides excellent sliding properties, allowing sliding between the inner and outer layers of the cable core 1, creating an effect similar to a rolling bearing. This low sliding friction resistance improves bending resistance, helps suppress wire and core breakage, enhances durability, and reduces safety hazards. Finally, a filler layer 4, made of powdered magnesium oxide, provides flame retardant and heat insulation for the data transmission cable. Since powdered magnesium oxide is non-combustible, when the outer layer of the data transmission cable burns, the filler layer 4 isolates the flame from the metal layer 2, ensuring the normal operation of the cable core 1. By incorporating microporous core 5, the structure of cable core 1 becomes more stable, and the overall dielectric constant becomes more uniform, thereby ensuring the stability and consistency of the data transmission cable's transmission performance. The shielding layer 6, which uses a reverse spiral braided structure of tin-plated copper wire and aluminum-magnesium wire, replaces the original single copper or aluminum wire braiding structure. The tin-plated copper wire is more rigid and has better conductivity, balancing flexibility and rigidity, significantly improving the data transmission cable's anti-interference capability.

[0023] The cable incorporates an oxygen-barrier fireproof layer 7, made of aluminum hydroxide. This layer significantly enhances the fire resistance and flame retardancy of the data transmission cable. The aluminum hydroxide undergoes an endothermic decomposition reaction during combustion, absorbing a large amount of heat from the surrounding air and lowering the surface temperature of the burning cable. The generated water molecules further absorb heat from the cable's surface, and the resulting metal oxide crust prevents further contact between oxygen and organic matter. Additionally, a flame-retardant layer 8, made of ceramicized silicone rubber, rapidly forms a hard, dense ceramic-like shell at high temperatures. This shell does not melt or drip in a fire environment, effectively isolating flames and preventing the spread of fire. During combustion, the ceramicized silicone rubber produces very little smoke, which is non-toxic and harmless.

[0024] The data transmission cable is equipped with a buffer layer 10 covering the outer wall of the flame-retardant layer 8, and a foamed armor layer 12 covering the outer wall of the buffer layer 10. The cross-section of the buffer layer 10 is designed as a corrugated structure. Several first tensile cores 9 are provided between the flame-retardant layer 8 and the buffer layer 10. The first tensile cores 9 not only further increase the tensile strength of the data transmission cable, but also prevent the buffer layer 10 from damaging the flame-retardant layer 8. Several second tensile cores 11 are provided between the buffer layer 8 and the foamed armor layer 12. The second tensile cores 11 not only further increase the tensile strength of the data transmission cable, but also prevent the buffer layer 10 from damaging the foamed armor layer 12.

[0025] The data transmission cable features a foamed armor layer 12, composed of multiple concentrically twisted foamed armor cores made of modified polypropylene foam. This foamed armor layer 12 replaces the traditional metal armor layer, significantly reducing the cable's weight. It absorbs external impact energy through its own deformation, effectively protecting the cable from damage. Furthermore, the cable includes an outer sheath 13 made of flame-retardant thermoplastic polyurethane elastomer. This outer sheath boasts significantly higher tensile strength and abrasion resistance than other sheath materials, along with outstanding tear resistance, low-temperature flexural strength, oil resistance, and aging resistance, further extending the cable's service life.
