Abstract
Description
Technical Field
[0001] This utility model relates to the field of information cable manufacturing technology, and in particular to a novel shielded network cable. Background Technology
[0002] With the rapid development of information technology, the demand for network communication is increasing, especially for high-speed data transmission. To meet these demands, network cables must not only ensure good signal transmission quality but also effectively resist external electromagnetic interference. Currently, most mainstream network cables on the market use a traditional cross-shaped structure to maintain the internal spatial layout of the cable and prevent mutual interference between the wire cores. However, this design suffers from low production efficiency and is prone to wire core damage, limiting its further application and development.
[0003] In response to these issues, the industry has proposed several improvement measures. One approach is to optimize the physical structure of the cable, such as adding a metal shielding layer or using higher-level insulation materials, to improve the overall performance of the cable.
[0004] Limitations of existing technology: Although existing technological improvements have enhanced the performance of network cables to some extent, they still cannot completely overcome the problem of stability degradation after prolonged use because their core structure has not fundamentally changed. Therefore, a new type of shielded network cable is proposed. Utility Model Content

[0006] This utility model provides a novel shielded network cable, which adopts the following technical solution:
[0007] A novel shielded network cable includes an iron wire, a hollow bracket insulation layer, wire cores, an aluminum foil shielding layer, a graphene shielding layer, a copper braided shielding layer, a PET Mylar waterproof layer, and an outer sheath protective layer. The iron wire is fixedly inserted through the center of the hollow bracket insulation layer. The hollow bracket insulation layer has multiple channels inside to accommodate the wire cores. The two strands of the wire cores pass through the channels. The two strands of the wire cores are jointly wrapped by the aluminum foil shielding layer. The graphene shielding layer is wrapped around the hollow bracket insulation layer. The copper braided shielding layer is wrapped around the graphene shielding layer. The PET Mylar waterproof layer is wrapped around the copper braided shielding layer. The outer sheath protective layer is wrapped around the PET Mylar waterproof layer.
[0008] By adopting the above technical solutions, the hollow bracket insulation layer can be extruded in one step instead of being placed before extrusion using the traditional cross-shaped structure. This not only improves production efficiency but also facilitates the stranding of the wire cores without damage or deformation, thereby improving the stability of cable performance. The aluminum foil shielding layer can effectively shield the double-stranded wire cores within the easy-to-access channels, forming an electromagnetic isolation layer and reducing electromagnetic interference to the wire cores. The graphene shielding layer and copper braided shielding layer further enhance the electromagnetic shielding performance of the multi-layered composite shielding structure, strengthening the cable's ability to resist external electromagnetic interference and making the cable more stable during use, ensuring high-quality and secure data transmission.
[0009] Optionally, the insulating layer of the lotus root-shaped hollow bracket is made of PP material.
[0010] By adopting the above technical solution, PP material has good insulation properties.
[0011] Optionally, the core includes a conductor and a conductor insulation layer wrapped around the surface of the conductor.
[0012] By adopting the above technical solution, the conductor insulation layer can provide insulation protection for the conductor, and the two wire cores need to be twisted together to reduce attenuation and signal crosstalk.
[0013] Optionally, the conductor insulation layer is made of PE material.
[0014] By adopting the above technical solutions, PE material has good insulation properties.
[0015] Optionally, the outer sheath protective layer includes an outer insulation layer, a pressure-resistant layer, a reinforcing layer, and a wear-resistant layer. The pressure-resistant layer is fixedly connected to the outer surface of the outer insulation layer, the reinforcing layer is fixedly connected to the outer surface of the pressure-resistant layer, and the wear-resistant layer is fixedly connected to the outer surface of the reinforcing layer.
[0016] By adopting the above technical solutions, the cables can be strengthened, their compressive strength and stability can be improved, and their service life can be extended.
[0017] Optionally, the compression-resistant layer is a rubber-filled layer.
[0018] By adopting the above technical solution, rubber has good elasticity and can play an impact resistance and buffering role when the cable is subjected to external pressure, thereby improving the cable's compressive strength and impact resistance.
[0019] Optionally, the reinforcing layer is a carbon fiber braided layer.
[0020] By adopting the above technical solutions, carbon fiber has extremely high structural strength, tensile strength and impact absorption capacity. When the cable is squeezed or bent, it is not easy for the cable to be damaged or broken. When the cable is punctured by a sharp object, it is not easy to puncture the cable, making the cable more durable in harsh environments and extending the service life of the cable.
[0021] Optionally, the wear-resistant layer is a nylon braided layer.
[0022] By adopting the above technical solution, nylon has extremely strong wear resistance, which can enhance the wear resistance of the cable surface and make the cable sheath less prone to damage.
[0023] In summary, this utility model has the following beneficial effects:
[0024] 1. This utility model, through the setting of the lotus root hollow bracket insulation layer, can be extruded in one step instead of the traditional cross-shaped insulation layer placed before extrusion. This not only improves production efficiency, but also facilitates the stranding of wire cores without damage or deformation due to compression, thereby improving the stability of cable performance.
