Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0016] like figure 1 As shown, a three-core flat cable with a small outer diameter according to the present invention has a flat structure, and two parallel phase cores 1 are arranged in the center of the cable. A ground core conductor 4 is wrapped with a wrapping tape 3 around the ground core conductor, and a sheath 5 is extruded outside the wrapping tape. The phase line core is composed of a phase line conductor 2 and a wrapping tape 3 wrapped around the phase line conductor 2; the phase line conductor 2 is formed by twisting several monofilaments 6; the ground line core The conductors 4 are arranged at equidistant intervals or are covered on the periphery of the phase core, and their diameter is the same as that of the monofilament 6 that constitutes the phase conductor; the ground core conductor 4 is a solid bare round conductor or an extruded insulated Solid round c...

Abstract

The invention discloses a three-core flat cable with a small outer diameter. The cable is of a flat structure, two paratactic phase wire cores are arranged in the center of the cable, a circle of ground wire core conductors are arranged outside the phase wire cores side by side, a wrapping tape is wrapped around the ground wire core conductors, and a protecting sleeve is wrapped around the wrapping tape in an extruded mode. The three-core flat cable has the advantages of being capable of being repeatedly moved, bent and vertically used, compact in structure, small in diameter and easy to machine, achieving convenient construction and the like.

Description

[0001] technical field [0002] The invention relates to the field of wires and cables, in particular to a three-core flat cable with a small outer diameter. Background technique [0003] In the prior art, the three-core cable generally has a structure in which three circular cores extruded with insulation are twisted, or three fan-shaped cores are twisted. The three-core cable core includes three third-class cores with the same conductor cross-section or two 2+1 cores with a large conductor cross-section and one conductor with a small cross-section. The twisting of three circular cores, especially the twisting of three 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 cores are easy to For this reason, filling materials are usually added and twisted together, and the outer layer needs to be tied tightly with a tape when t...
