Process for manufacturing spliced conductor type cable

Abstract

The invention discloses a process for manufacturing a spliced conductor type cable. The process includes the steps that metal blanks are utilized to draw conductors, the conductors comprise the inner conductors and the outer conductors, wherein the cross sections of the inner conductors are circular, the inner conductors are formed by a plurality of core wires of which the cross sections are semicircular or of a sector shape, the cross sections of the outer conductors are of a circular ring shape, the outer conductors and the inner conductors are spliced to form circular cross sections, and the outer conductors are formed by splicing a plurality of core wires of which the cross sections are of a tile shape; the core wires of the inner conductors and the core wires of the outer conductors are spliced into wires of which the cross sections are circular, and then the wires are twisted around a center shaft by a wire twisting machine, wherein the cross sections of the core wires are semicircular or of the sector shape or of the tile shape; inner insulating layers wrap the wires in an extrusion molding mode, the plurality of sets of wires wrapped by the inner insulating layers are circular, and outer sheathes wrap the plurality of sets of twisted wires. According to the process, the core wires are machined into the semicircular shape or the sector shape or the tile shape which can be spliced to the circular shape, then, the core wires are twisted to produce the wires, and therefore gaps among the core wires are reduced, the compaction degree of the wires is increased, and the geometric dimensions of the wires are reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a manufacturing process for a spliced ​​conductor type cable. Background technique [0002] Cables are made by drawing, twisting and covering three processes. Cables are usually twisted wires, each with inner insulation, twisted around a center, and covered with a highly insulating covering. And each wire is formed by twisting a plurality of core wires. In the prior art, the cross-section of each core wire is circular. When multiple core wires are twisted, there will be a gap between the core wires, resulting in insufficient compression, resulting in a large geometric size of the wire and a large occupation. Usable area needs to be improved urgently. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to propose a splicing conductor type cable manufacturing process to improve the compression degree of the...
