Anti-interference cable and production equipment thereof

Abstract

The invention discloses an anti-interference cable. The cable comprises a wire core and a supporting assembly. The outer surface of the wire core is wrapped with an insulating layer, the supporting assembly comprises a supporting ring and a supporting strip, the section of the supporting strip is cylindrical, six sets of supporting rods are annularly arranged between the supporting strip and the insulating layer at equal intervals, the supporting strip is wrapped with a metal corrugated pipe, and a rubber sleeve is arranged outside the metal corrugated pipe. The invention further provides production equipment of the anti-interference cable. The equipment comprises a base, wherein an extruder outer box body is fixedly mounted on the upper surface of the base. A cable forming cylinder is rotationally mounted in the extruder outer box body. Extrusion positioning assemblies are symmetrically arranged at the top of the extruder outer box body and the bottom of the base. Each extrusion positioning assembly comprises an electric push rod, positioning rollers are annularly arrayed in an arc-shaped plate at equal intervals, arc-shaped recesses are formed in the surfaces of the positioning rollers, and the situation that internal breakage is caused by forming extrusion in the extrusion process is prevented.

[0002] As the carrier of current, the cable transmits the power of the power station to thousands of households through the cable. It is an indispensable electrical component in modern life. During the production process of the cable, the cable is produced and processed from the inside to the outside. The production of the conductor, and then adding insulating layers, shielding layers and protective layers layer by layer outside the conductor, the more high-end cables, the more superimposed layers, the more complex the structure, and the lack of internal strength. , there are often partial breaks inside the cable, and the radiation and leaked electromagnetic waves of the cable not only seriously interfere with the normal operation of other electronic equipment, but also lead to equipment dysfunction and transmission errors.

[0003] In the cable production process, as the conductor enters the extruder, it is coated on the conductor and is extruded out of the extruder together with the conductor to form an insulating layer. If the air bubbles exist, the air bubbles will be retained in the insulating layer as the polymer insulating material hardens, which leads to uneven thickness of the insulating layer, thus affecting the quality of the cable. At this time, due to the structure of the cable, it cannot be disassembled and reprocessed , so the cables can only be sawed short or downgraded, resulting in losses for the enterprise and increased production costs
