Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Referring to Fig. 1, an anti-interference high-frequency data transmission cable provided by this embodiment includes a wire 1, a ground wire 2, an aluminum foil layer 3, a copper wire braid 4 and an outer layer 5, the aluminum foil layer 3, The copper wire braiding layer 4 and the outer coating layer 5 are coated on the wire 1 sequentially from the inside to the outside. The utility model has a reasonable structural design, and the wire 1 is cleverly covered with an aluminum foil layer 3, and the shielding effect is good. Strong anti-radiation and anti-interference ability; at the same time, the aluminum foil layer 3 is covered with a copper wire braid layer 4, which can effectively shield the entire cable, further improve anti-interference performance, reduce external interference, and effectively ensure data signal transmission.

The ground wire 2 is located between the aluminum foil layer 3 and the braided copper layer 4 . The outer covering layer 5 is an insulating layer made of PVC material, which can effectively protect the wire 1, is not easy to harden, is not easy to be damaged and worn by external forces, has high wear resistance and aging resistance, and can effectively protect personal safety and The performance of the power cord.

The wire 1 is formed by twisting three wires. Preferably, three wires and multiple filling tension ropes are twisted together to form a wire 1 with a circular cross section, and the wires and filling tension ropes are twisted skillfully, so that the filling tension ropes can fully fill the space between the wires The gaps form a tight and solid support to avoid the flattening of the wires when they are bent, effectively guarantee the wires, and greatly improve the tensile capacity.

The electric wire includes a conductor formed by twisting a plurality of core wires and a PVC insulating layer covering the conductor. The core wire is bare copper wire or tinned copper wire.
