Insulated light-weight multi-core cable, threading jig and manufacturing method

Abstract

The invention provides an insulated light-weight multi-core cable, a threading jig and a manufacturing method. The insulated light-weight multi-core cable comprises a sheath and an insulated solid inner core which fills and is sleeved in the sheath; at least more than two mounting wire slots are annularly formed in the outer circumferential surface of the insulated solid inner core at equal intervals; an insulated barrier strip is formed between every two adjacent mounting wire slots; conductor cables are correspondingly installed in the mounting wire grooves; and every two adjacent conductorcables are isolated through the insulated barrier strip. The insulated light-weight multi-core cable is simple and convenient in production steps, the overall outer diameter is reduced, overall weightreduction is achieved, the size is reduced, the production period is shortened, and the light-weight effect is achieved; the formed multi-core cable can be bent towards any direction, so that bendingwiring is facilitated; and the insulated solid inner core can be prevented from rotating through the corresponding threading jig, so that the use is convenient.

Description

technical field [0001] The invention relates to a cable, in particular to an insulating and lightweight multi-core cable, a threading jig and a manufacturing method. Background technique [0002] A cable, usually composed of several wires or groups of wires, is a wire that transmits power or information from one place to another. At present, conventional three-core unshielded cables, such as power cords, are produced by extruding the conductors with an insulating layer, twisting the three cores, and then extruding the outer sheath, which requires three processes of insulation, cabling, and sheathing. Although this production method is relatively mature and widely used, it has the disadvantages of long production cycle, large production process loss and low production efficiency. In this invention, only one sheathing process is required to complete the production, and the insulation separation and cable formation of the conductors are all formed at the sheathing line, which ...

Problems solved by technology

The disadvantage of flat wires is that they do not have the flexibility of round wires. When wiring, the wires cannot be bent in any direction like round wires, especially for curved wires with a short length of meters. The wide surface is bent, which will cause the deformation of the wire and the internal conductor will shrink due to severe stretching
