In order to solve the above-mentioned technical problems, this embodiment provides a vehicle-mounted ethernet cable, as shown in fig. 1, including at least two twisted pair-shaped core wires 10, and a first shielding layer 20, a second shielding layer 30 and an outer coating layer 40 sequentially coated on the core wires 10, wherein the core wires 10 include a plurality of conductors 11, and pp foam layers 12 and pp skin layers 13 sequentially coated on the conductors 11. Through pp foam layer 12 and pp cortex 13 as the insulating layer of heart yearn 10, adopt pp foam layer 12 and pp cortex 13's foam skin structural design, and then realize lower more even insulating dielectric constant, provide stable, even medium for the high-speed transmission of signal, reduce the loss in the signal transmission process, possess stable signal transmission ability, promote wire rod impedance and decay simultaneously, keep high transmission rate and high frequency performance's stability, form double-deck shielding through first shielding layer 20 and second shielding layer 30, make the network line effectively shield the electromagnetic interference that each components and parts produced when practical application.
Specifically, the foaming degree of the pp foam layer 12 is 40%, so that the pp foam layer has a lower dielectric constant, provides a stable and uniform medium for high-speed transmission of signals, and reduces loss in the signal transmission process; the temperature resistance level of the foamed PP material after foaming can still be ensured to be between-40 and 105 ℃, so that the foamed PP material has an extremely long service life and can still ensure stable transmission of signals in high and low temperature environments. The foam skin structure design of the PP foam layer 12 and the PP skin layer 13 is adopted, so that the capacitance in water can be reduced, the impedance and attenuation of wires can be improved, and meanwhile, the selected PP material can meet the long-term aging requirement of 105 ℃ X3000 h.
The two core wires 10 form a differential pair twisting group through twisting, and the pair twisting structure can better shield external interference signals, so that lower mode conversion of wires during signal transmission can be ensured. The pair pitch of the two core wires 10 is 19mm, and the adopted pair pitch of 19mm enables the two core wires 10 to have higher bandwidth, so that the attenuation of the network wire before the frequency of 4GHz is free from resonance, and the stable transmission of high-frequency signals is ensured. The pair twisting adopts a full-back twisting bow wire, the stress generated by twisting the core wire 10 is completely released, the flexibility of the wire is improved, and the wire is ensured to have a more stable structure, so that the wire is ensured to have stable signal transmission capability when being fixedly and movably laid.
Further, each core wire 10 includes 7 conductors 11, and the exemplary conductors 11 are high-flexibility concentric stranded compact tin-plated annealed soft copper conductors, and the structural design is that 1 conductor 11 is arranged in the center, and the other 6 conductors 11 are surrounded by the conductor 11 in the center. After stranding, the conductors are compacted and molded through a compacting die, the compacting coefficient is 0.9, and then 7 compacted and stranded conductors are softer and more round, so that high flexibility of the wires is guaranteed, and meanwhile, a uniform and stable transmission medium is provided for high-speed signal transmission.
The first shielding layer 20 is a double layer aluminum foil. The thickness of the aluminum foil is 0.5 mu m, the double-layer aluminum foil is used as a wrapping shielding layer, the double-layer aluminum foil is wrapped on the two core wires 10 through the constant Zhang Lirao, the double-layer aluminum foil not only enables the network wire to have a better shielding effect, but also has a fixing and protecting effect on the core wires 10, so that the double-layer aluminum foil is more stable in structure and improves the anti-interference capability in practical application.
Further, the second shielding layer 30 is formed by braiding tin-plated copper, the braiding density is more than 85%, double-layer shielding is formed after the second shielding layer contacts with aluminum foil, the shielding effect is greatly improved, shielding attenuation is guaranteed to be lower than 55dB, and electromagnetic interference generated by other components and parts of the wire rod can be effectively shielded during practical application.
