AI Technical Summary
During the twisting process, the conductor materials of the existing data cables are the same, so that the SMIC layer and the outer conductor cannot be tightly wrapped, and there are creeping gaps, which affect the distortion of video signal transmission.
Copper-tin alloy or copper-magnesium alloy material with a conductor hardness greater than that of the wire core, and the circle diameter formed on the contact side of the conductor and the wire core is smaller than the wire core diameter, ensuring that the conductor and the wire core are closely wrapped around and eliminating creeping gaps.
The video signal transmission is free of distortion, and the conductor is tightly wound with the wire core, avoiding the occurrence of signal distortion.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a data transmission cable. Background Art
[0002] With the gradual development of the communication industry, the requirements for the electrical performance of high-speed and high-frequency data cables have also been greatly improved. The current data cables use a structure manufacturing process of twisting conductors with a single specified wire diameter. It is extremely easy that during the twisting process of the core strand conductor and the outer conductor, since the conductors are all made of materials with the same strength for twisting operation, the core strand and the outer conductor cannot be tightly wound, and there are slight creeping gaps. During the manufacturing process of the outer rubber material of the electronic wire, it must pass through the internal pressure of the extruder die. The twisted conductor strands will creep due to the internal pressure of the die, resulting in changes in the front and rear sections of the twisting pitch, thus affecting the distortion of the video signal.
[0003] Therefore, it is necessary to design a data transmission cable to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a data transmission cable aiming at the problem of video signal distortion existing after the production of the cable in the prior art.
[0005] The technical solution of the utility model is: a data transmission cable, comprising a core, a conductor layer and an insulating layer which are arranged in sequence from inside to outside; the conductor layer comprises a plurality of conductors stranded outside the core, and the hardness of the conductors is greater than that of the core; the diameter of the circle formed by the side of the plurality of conductors in contact with the core is less than or equal to the diameter of the core.
[0006] The material of the core is pure copper.
[0007] The material of the conductors is copper-tin alloy or copper-magnesium alloy.
[0008] The material of the insulating layer is polyvinyl fluoride.
[0009] The diameter of the core is greater than that of the conductors.
[0010] The number of the cores is one; the number of the conductors is eight.
[0011] By adopting the above technical solution, the utility model has the following beneficial effects: the hardness of the conductors of the utility model is greater than that of the core, and the diameter of the circle formed by the side of the plurality of conductors in contact with the core is less than or equal to the diameter of the core, thus ensuring that after the conductors are stranded, they are more tightly wound around the core, without slight creeping gaps, and thus ensuring that the video signal transmission will not be distorted.
