[0002] In the current high-speed data transmission process, electromagnetic interference between cables is an important problem that needs to be solved urgently. Electromagnetic interference will affect the integrity and reliability of data. The existing cable structure cannot effectively solve this problem, resulting in reduced transmission quality and limited transmission rate. Therefore, it is urgent to develop a new type of high-speed transmission cable to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0017] A high-speed transmission cable based on independent shielding space, see Figure 1 , which includes an outer sheath 10, a cross separator 20, and four wires 30;

[0018] Each electric wire 30 includes a wire pair 40, a shielding layer 50 and a conductive protective layer 60 arranged from the inside to the outside. The shielding layer 50 is arranged on the outer periphery of the whole formed by the wire pair 40, and the outer periphery of the shielding layer 50 is covered with the conductive protective layer 60.

[0019] The inner cavity of the outer sheath 10 is provided with a cross partition 20 along the length direction. The cross partition 20 divides the circular inner cavity into four sector-shaped area cavities 70 of equal arc. A wire 30 is arranged in each sector-shaped area cavity 70 .

[0020] In a specific implementation, the four wires 30 are of the same model, and the wire pair 40 in the central cavity of each wire 30 is formed by two conductors 41 covered with a corresponding insulating layer 42 on the outer periphery;

[0021] The outer ring of the insulating layer 42 formed by the combination of the wire pairs 40 is provided with a shielding layer 50, and the shielding layer is a braided shielding layer 50, and the braided shielding layer is tightly woven to form a complete shielding network;

[0022] The conductive protective layer 60 is coated on the outer circumference of the shielding layer 50 . The outer circumference of the conductive protective layer 60 is provided with uniformly distributed inner grooves 61 . The inner grooves 61 guide the electromagnetic waves to scatter in a specific direction, thereby reducing the crosstalk between different wires.

[0023] In specific implementation, the excess cavity between the outer surface of the wire pair 40 and the inner wall of the shielding layer 50 is filled with a first flame-retardant filling rope 80, and the excess cavity formed by the outer surface of the conductive protective layer 60 of the wire 30 and the fan-shaped area cavity 70 is filled with a second flame-retardant filling rope 90, which ensures the beauty of the appearance of the entire cable.

[0024] In specific implementation, the cross divider 20 includes a center block 21 and four straight edges 22. The connection positions of the center block 21 corresponding to two adjacent straight edges 22 are all arc transitions 211, and the ends of the straight edges 22 corresponding to the positions contacting the outer sheath 10 are semicircular surfaces 221 to ensure that the outer sheath 10 will not be damaged.

[0025] Its working principle is as follows: the cross divider divides the circular inner cavity into four sector-shaped area cavities with equal arcs, and a wire is arranged in each sector-shaped area cavity. Each wire has an independent shielding layer, and these shielding layers are isolated from each other by the cross divider, and each wire also includes a conductive protective layer, which further isolates the electromagnetic interference between each other; through the independent shielding space design, it effectively reduces the electromagnetic interference between line pairs, thereby improving the integrity and reliability of data transmission.
