Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0018] like figure 1 As shown, a curved five-core flat cable according to the present invention has a flat structure, three parallel phase cores 1 are arranged in the center of the cable, and a half-circle of ground wires are arranged side by side outside the phase core 1 The core conductor 4 and several neutral wire cores 7 in a half circle, the ground wire core conductor 4 and the neutral wire core 7 are wrapped with a wrapping tape 3 , and the wrapping tape is extruded and wrapped with a sheath 5 . 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 neutral line core 7 is composed of a neutral conductor 8 and an outer insulation layer extruded on the neutral conductor 8 9; the phase line conductor 2 is formed by twisting several monofilaments 6; the ground line core conductor 4 and the neutral...

Abstract

The invention discloses a bent type five-core flat cable. The cable is of a flat structure, three paratactic phase wire cores are arranged in the center of the cable, a half circle of ground wire core conductors and a half circle of neutral wire cores are arranged outside the phase wire cores side by side, a wrapping tape is wrapped around the ground wire core conductors and neutral wire cores, and a protecting sleeve is wrapped around the wrapping tape in an extruded mode. The five-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 electric wires and cables, in particular to a curved five-core flat cable. Background technique [0003] The five-core cable in the prior art is usually constructed by twisting five circular cores extruded with insulation, or twisting four fan-shaped cores and one circular core. The five-core cable core includes five fifth-grade cores with the same conductor cross-section, three "three big and two small" cores with large conductor cross-sections and two small conductor cross-sections, or "four big four" with large conductor cross-sections and one small conductor cross-section. A small" core. The twisting of five circular cores, especially the twisting of five 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...
