Three-core compound flat cable with control line core pairs

A technology for controlling wire cores and flat cables. It is applied in the direction of flat/ribbon cables, power cables with shielding layers/conductive layers, insulated cables, etc., which can solve the problems of increased cable length and uncompact structure, and reduce laying costs. Space, saving filling material and strapping, convenient construction

Problems solved by technology

[0006] In the prior art, there is a structure using a flat cable. Although it can be moved repeatedly, bent, or used vertically, the three cores and the control cable core are arranged in parallel at the same time, which increases the length of the cable and the structure is not compact.

Embodiment Construction

[0015] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a three-core composite flat cable with a pair of control wire cores, the cable has a flat structure, the center of the cable is paralleled and directly dragged two phase cores 1, and the phase core 1 is wrapped around the wrapping tape 2, wrapped 24 ground wire cores 3 and 2 pairs of control wire core pairs 4 are arranged side by side outside the belt 2, and the outer sheath 5 is extruded on the outermost layer of the cable.

[0017] The phase core 1 is composed of a phase conductor 7 composed of several monofilaments 6 and an insulating layer 8 wrapped around the phase conductor 7 .

[0018] The pair of control wire cores 4 is composed of two control wire cores 9 pulled directly, a metal braided shielding layer 10 wrapped around the two control wire cores 9 and a thin sheath 11 extruded outside the metal braided shie...

Abstract

The invention discloses a three-core compound flat cable with control line core pairs. The three-core compound flat cable is of a flat structure, two phase line cores are linearly dragged at the center of the cable side by side, a wrapping belt wraps the phase line cores, a plurality of ground wire cores and at least one control line core pair are arranged outside the wrapping belt side by side, and an outer sheath is arranged at the outermost layer of the cable in an extrusion mode. The three-core compound flat cable with the control line core pairs is small in signal interference, can simultaneously transmit electricity and control signals, and is capable of being repeatedly moved, bent and perpendicularly used, compact in structure, small in outer diameter, easy to process and convenient to construct.

Description

[0001] technical field [0002] The invention belongs to the field of electric wires and cables, in particular to a three-core composite flat cable with control core pairs. Background technique [0003] With the popularization of computer technology and the rapid development of the information industry, the intelligentization of residential quarters has become the development trend of modern buildings. , Under certain conditions, it is included in the integrated wiring system, and it is connected to form a complete and complete whole to meet the requirements of a high degree of intelligence. [0004] In the prior art, the three-core composite cable with a pair of control cores usually has the structure of twisting the control cable core with three extruded round cores with insulation, or twisting three fan-shaped cores and then twisting with the control cable core. . The three-core cable core includes three third-class cores with the same conductor cross-section or two 2+1...
