[0013] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0014] Example

[0015] In order to solve the above technical problems, this embodiment provides a high-strength vehicle-mounted Ethernet cable, such as Figure 1As shown, it includes two twisted core wires 10, and a tape layer 20 and an outer layer 30 coated on the core wire 10. The core wire 10 includes a tinned copper-clad steel conductor 111 located in the center, a plurality of tinned copper wire conductors 112 twisted and coated on the tinned copper-clad steel conductor 111, and an insulating layer 113 coated on the periphery of the tinned copper wire conductor 112. The conductor uses a 0.25mm tinned copper-clad steel conductor with a conductivity of 30% in the center, which not only makes the wire have ultra-high strength, but also ensures that the wire will not be affected by external forces during signal transmission. At the same time, due to the skin effect of its signal transmission, the tinned copper wire conductor 112 coated on the outer layer of the tinned copper-clad steel conductor 111 will provide a uniform and stable transmission medium for signal transmission, thereby ensuring the stability of signal transmission. It meets the current gigabit transmission rate requirements of vehicle-mounted network cables, and at the same time ensures that the network cable has sufficient strength to ensure stable transmission in the complex environment of the car.

[0016] Specifically, there are at least 8 tinned copper wire conductors 112, which are twisted and completely covered on the outer periphery of the tinned copper clad steel conductor 111, which can ensure the roundness of the entire conductor after twisting and provide a uniform medium for signal transmission. Among them, the wire diameter of the tinned copper clad steel conductor 111 is 0.25-0.3mm, and the wire diameter of the tinned copper wire conductor 112 is 0.15-0.2mm. Preferably, the wire diameter of the tinned copper clad steel conductor 111 is 0.25, and the wire diameter of the tinned copper wire conductor 112 is 0.15mm. The outer layer of 8 0.15mm annealed tinned copper wire conductors 112 are tightly twisted and completely cover the central tinned copper clad steel conductor 111. The design of this conductor not only makes the wire have ultra-high strength, ensuring that the wire will not be affected by external forces during signal transmission, but also the tinned copper wire conductor 112 provides a uniform and stable transmission medium, thereby ensuring the stability of signal transmission.

[0017] In the above scheme, the 30% conductivity tinned copper clad steel conductor 111 used in the center of the core wire 10 can ensure that the wire breaking force is above 80N, and at the same time ensure that the conductor resistance after twisting can meet the requirements of 26AWG conductor resistance.

[0018] Furthermore, in some embodiments, the insulating layer 113 can be made of modified polypropylene, which has higher temperature resistance and excellent flame retardant properties. The dielectric constant of 2.2 can ensure that the wire can be made with a smaller wire diameter while meeting the signal transmission requirements, thereby saving more space for vehicle wiring; it can ensure that the wire can work stably for a long time under high temperature conditions of 125°C, and its high flame retardancy ensures that the application of the wire has higher safety characteristics.

[0019] In order to ensure the stability of the twisted wire structure, this solution is different from the traditional wrapping. The tape layer 20 of this solution adopts a more tightly fitting wrapping method. The wrapping of the tape layer 20 makes the twisted structure more stable. At the same time, it prevents the outer layer 30 from adhering to the core wire 11 when the outer sheath is extruded. The wrapping is tighter, which reduces the air in the middle of the twisted pair group and makes the signal transmission more stable. In addition, in order to ensure that customers can avoid manually cutting off the excess tape layer 20, the tape layer 20 of this solution adopts a polyester tape with a self-adhesive layer, and the self-adhesive layer faces outward. When the outer layer 30 is extruded, the self-adhesive layer of the polyester tape is melted by the high temperature during extrusion, and then tightly fits on the outer layer 30. When the customer processes and peels, the outer layer and the polyester tape can be opened at one time to avoid repeated processing and avoid wasting time caused by secondary peeling.

[0020] Furthermore, the outer layer 30 is a thermoplastic elastomer layer resistant to 125°C. It has good chemical resistance, high temperature resistance, corrosion resistance, wear resistance, low temperature flexibility, etc., and its service life in the harsh environment of the car can be greater than 15 years. In addition, this outer layer 30 has a more stable dielectric constant, which provides strong support for the stability of the signal transmission of the core wire 10 while protecting the core wire 10.

[0021] In summary, the present application scheme is to coat the outer periphery of the twisted core wire with a tape layer and an outer layer, and the core wire includes a tinned copper clad steel conductor located in the center, a plurality of tinned copper wire conductors twisted and coated on the tinned copper clad steel conductor, and an insulating layer coated on the outer periphery of the tinned copper wire conductor. The conductor adopts a central tinned copper clad steel conductor, which not only makes the wire have super high strength, but also ensures that the wire will not be affected by external force during signal transmission. At the same time, due to the skin effect of its signal transmission, the tinned copper wire conductor coated on the outer layer of the tinned copper clad steel conductor will provide a uniform and stable transmission medium for signal transmission, thereby ensuring the stability of signal transmission. It meets the current gigabit transmission rate requirements of vehicle-mounted network cables, while ensuring that the network cable has sufficient strength to ensure stable transmission in the complex environment of the car.

[0022] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
