Compact four-core ribbon cable

Abstract

The invention discloses a compact four-core ribbon cable which is of a flat structure. The center of the cable is provided with three parallel phase cable cores. A plurality of ground cable core conductors are distributed outside the phase cable cores in parallel. Wrapping tape wraps the ground cable conductors. Protecting sleeves wrap the wrapping tape in an extruding mode. The compact four-core ribbon cable has the advantages of being capable of being moved repeatedly, bent and vertically used, compact in structure, small in outer diameter, easy to process, convenient to construct and the like.

Description

[0001] technical field [0002] The invention relates to the field of wires and cables, in particular to a compact four-core flat cable. Background technique [0003] The four-core cable in the prior art generally has a structure in which four circular cores extruded with insulation are twisted, or four fan-shaped cores are twisted. The four-core cable core includes four fourth-class cores with the same conductor cross-section or three 3+1 cores with a large conductor cross-section and one conductor with a small cross-section. The twisting of four circular cores, especially the twisting of four circular cores with different cross-sections, has a large gap between the cores, which not only makes the roundness of the cable poor, but also tends to loosen during extrusion and construction, and the wires The core is prone to shifting. For this reason, filler materials are usually added and twisted together. When twisting, the outer layer needs to be tied tightly with tape, and ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, there is a structure using a flat cable, although it can be moved repeatedly, bent, or used vertically, but the four cores are arranged in parallel at the same time, which increases the length of the cable, and the structure is not compact
