[0019] like Figure 1 and Figure 2 As shown, a high-performance UTP communication cable for automobiles includes, from inside to outside, a conductor 1, an insulating layer 2, a wrapping tape 3, and a sheath layer 4;

[0020] Conductor 1 is composed of 7 strands of fine copper-tin alloy wires with a diameter of 0.15-0.16 mm, with a stranding direction of S and a pitch ratio of 13-15.

[0021] Insulation layer 2 is made of polypropylene (PP) material, with a thickness of 0.17-0.20 mm and a concentricity of >95%;

[0022] The wire core formed by the conductor 1 and the insulating layer 2 is twisted into two strands, the twisting direction is S, and the twisting pitch ratio is 7-10;

[0023] The wrapping tape 3 is made of a film tape with single-sided adhesive of PP material, with a thickness of 0.02-0.05 mm and a width of 10 mm. It is synchronously wrapped in the S direction during the stranding process (the longitudinal wrapping structure is generally used on the market), with the adhesive side of the single tape facing outward (the adhesive side faces the sheath layer 4);

[0024] The sheath layer 4 is made of polystyrene elastomer (TPE-S) material, with a thickness of 0.6-0.8 mm and a concentricity of more than 85%.

[0025] The effects of the traditional UTP communication cable and the high-performance UTP communication cable of the utility model are compared as follows:

[0026] Traditional UTP communication cable:

[0027] Return loss: 20-14.8dB (1-66MHz);

[0028] Attenuation: 0.6-7.8dB / 10m(1-100MHz);

[0029] LCL / LCTL: 46-34dB (1-200MHz);

[0030] The high-performance UTP communication cable of this utility model:

[0031] Return loss: 34-27dB (1-66MHz);

[0032] Attenuation: 0.4-3.7dB / 10m (1-100MHz);

[0033] LCL / LCTL: 65-55dB (1-200MHz);

[0034] Among them, return loss: the larger the absolute value, the better the communication performance; attenuation: the smaller the absolute value, the better the communication performance; LCL / LCTL: the larger the absolute value, the better the communication performance.

[0035] The high-performance UTP communication cable of the utility model uses a high-conductivity alloy material as the conductor, which reduces the weight of the cable and improves the electrical conductivity and flexibility of the cable. By using a low-dielectric-constant PP material as the insulating layer, the high-temperature resistance and data transmission performance of the cable are improved, so that it can work normally in a high-temperature environment of 125 degrees, thereby improving the safety and reliability of the car. By using a PP wrapping tape as the isolation layer structure, the integrity and stability of the cable structure are effectively guaranteed, thereby improving the communication transmission capacity of the cable and ensuring the stable operation of the car. By using flame-retardant and weather-resistant TPE-S material as the sheath layer, the cable is protected from the external environment, thereby improving the service life and safety of the cable.

[0036] The utility model optimizes the structure and materials of the conductor, insulation layer, wrapping tape and sheath layer to achieve high-speed, high-reliability and low-loss communication performance. At the same time, the cable also has good flexibility, wear resistance and high temperature resistance, and can adapt to the complex working environment and variable installation conditions inside the car.

[0037] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
