Process for manufacturing shielding soft cable with two-core semicircular conductor for communication power supply

Abstract

The invention discloses a process for manufacturing a shielding soft cable with a two-core semicircular conductor for a communication power supply. The process mainly comprises a process for manufacturing the semicircular conductors of two core wires, a process for manufacturing the two core wires and a process for cabling, namely a braided wire consists of single wires; a plurality of braided wires form the conductor; the conductor sequentially enters a first frame-type strander and a die for re-stranding; the die behind the first frame-type strander is a circular die; the dies behind the subsequent frame-type stranders are semicircular pinch roller dies consisting of upper pinch rollers and lower pinch rollers; the conductor is gradually formed into a semicircular conductor in the process of passing through the semicircular pinch roller dies; by passing through the last frame-type strander and the semicircular pinch roller die, the semicircular conductor is formed and wrapped with a layer of binding strip so as to be fixed; insulation layers are squeezed outside the two semicircular conductors respectively so as to form the core wires; a die core and a die sleeve of a squeezing die are semicircular; planes of the two core wires are stranded relatively; the two core wires are cabled by pre-stranding; and a wrapping layer, a shielding layer and an outer sheath are wrapped outside the stranded core wires. The process is advanced and practical and is low in investment. The shielding soft cable with the two-core semicircular conductor for the communication power supply manufactured by using the process has high roundness, smaller outer diameter, high heat dissipation performance and low manufacturing cost and occupies a small space.

Description

technical field [0001] The invention relates to a manufacturing process of a power cable, in particular to a manufacturing process of a shielded flexible cable with two semicircular conductors for a communication power supply. Background technique [0002] Existing cables for communication power supply mostly have two cores, and the conductors of the core wires are generally round. In order to ensure the roundness of the cable, the manufacturing process of adding fillers to the cable core is adopted, resulting in a larger outer diameter of the finished cable and lower heat dissipation. The performance is poor, the cable laying takes up a lot of space, and the manufacturing cost of the cable also increases. The shielded flexible cable with two-core semicircular conductors for communication power supply can maintain good roundness without adding fillers. The outer diameter of the finished cable is small, the heat dissipation is good, and the cable laying takes up little space....
