Abstract

The invention provides a compact type three-core combined flat cable with control cable cores. The compact type three-core combined flat cable comprises a power cable core, a wrapping layer, the control cable cores and a protection sleeve all of which are wrapped sequentially from interior to exterior. The compact type three-core combined flat cable is characterized in that the power cable core comprises two phase cable cores which are parallel and pulled directly, a plurality of ground cable core conductors are distributed outside the phase cable cores in parallel in a flat mode, and the control cable cores are distributed outside the power cable core in a flat mode. According to the compact type three-core combined flat cable, a ground cable core twisted and combined with two phase cable cores in the prior art is divided into the cable conductors, the cable conductors are distributed outside the two parallel phase cable cores in parallel in the flat mode, the phase cable core in charge of power transmission is arranged at the innermost layer, the effect similar to that of steel wire armoring is achieved, the phase cable cores are well protected, damage caused by external force is effectively relieved, the shielding effect is achieved, and electromagnetic interference to surrounding electrical equipment and external electromagnetic interference are reduced effectively.

Description

A kind of compact three core composite flat cables with controlling core

Technical field

The present invention relates to power cable field, specifically a kind of five core composite flat cables with controlling core.

Background technology

Develop rapidly along with the universal and information industry of computer technology, intelligent residential areaization has become the development trend of modern architecture, by the comprehensive wiring system that formed by composite cable etc. the communication in intelligent construction, computer and various device and facility, include under certain conditions comprehensive wiring system in, be interconnected to form complete supporting integral body, to realize highly intelligentized requirement.

The compact three core composite flat cables of the band control core of prior art, structure is stranded by controlling cable core and three circular cores that are extruded with insulation conventionally, or three segment conductor-cores are stranded rear stranded with control cable core.Three-core cable core comprises third-class core that three cross-sectional area of conductor are identical or two cross-sectional area of conductor are large, a 2+1 core that cross-sectional area of conductor is little.No matter be the stranded of which kind of form, core gap is larger, not only make cable roundness poor, and extrude and the process such as construction in easily loose, and core easily channels bit, conventionally add packing material stranded together, and skin need be tightened with band when stranded for this reason, after stranded or stranding, extrude again sheath.This structure band is controlled three core composite cables of cable core, and not only cable core poor stability, and material usage is large, has also increased cable weight and cost.As adopt three stranded segment conductor-core structures, although cable core stability improves, core is processed into sector structure, processes round core complicated, needs strict control segment angle and fan-shaped height, and easily occurs the phenomenons such as in uneven thickness, insulating barrier splits; Secondly, no matter be three core composite cables of the band control cable core of which kind of stranded form, lay configuration, increases actual core length, wastes material, increases weight, and cable cost increases; Again, this structure also makes the outside diameter of cable larger, especially large specification cable, and large external diameter has not only increased manufacture, transportation difficulty, and takies that to lay space large.Besides, the composite cable power core of structure is larger to the electromagnetic interference of control core conventionally.

Adopt circular shape concentric structure, can dwindle the outside diameter of cable, reduce the waste of material of stranded increase length, alleviated weight, not only reduce to account for deposited space, easy construction, and reduced cost, be also conducive to reduce electric energy loss.But the outside diameter of cable of this structure still very greatly, highly high, when laying in wire casing, especially need multi-cable simultaneously during overlapping laying, take that to lay space still very large, in small space, limited use; Secondly, many round cables during laying installation, are easily wound around between cable together, and identification difficulty, working service trouble; Again, the identification of round cable core difficulty, particularly three uiform section conductors, need every core all to identify; Besides, while using round cable, due to its constructional feature, the torsional moment that makes whole cable is zero more difficult, a lot of occasions use cables also need repeatedly to move, bending, or vertically use, the torsion adding when the torsion of cable self and manufacture, and the torsion increasing is not noted in installation, especially when vertical use, the stack of cable lower end is born and is discharged the twisting resistance transmitting above, therefore twisting resistance is maximum, therefore after using the several months, can be distorted distortion, bulge, broken skin until the heart yearn that fractures.These are not only easily accidents caused, cause cable short circuit or damage equipment; And cause cable useful life to shorten.Therefore still have and be worth improved place.

In prior art, there is the structure that adopts flat cable, although can repeatedly move, bending, or vertically use, three cores and control cables cable core are arranged in parallel simultaneously, have increased the length of cable, and structure is not compact.

Summary of the invention

The present invention overcomes the shortcoming that prior art exists, a kind of simultaneously transferring electric power and control signal are provided, can repeatedly move, crooked, vertically use compact conformation, external diameter is little, and the band that is easy to processing and convenient construction is controlled the compact three core composite flat cables of core.

The present invention includes from inside to outside wrapped successively power cable core, lapping layer, control core and sheath, it is characterized in that: described power cable core comprises two phase cores that directly drag side by side, and phase core becomes flat to be placed with side by side some ground wire core conductors outward; Controlling core becomes flat to be arranged in side by side outside power cable core.

Further improve, the described equidistant gap arrangement of ground wire core conductor or to be covered with phase core peripheral is identical with the filament diameter size of phase line core conductor.

Further improve the described equidistant gap arrangement of control core or to be covered with power cable core peripheral.

Further improve, described lapping layer is metal screen layer.

Further improve, described phase core is the some solid naked round conductors that extrude or the some filled circles conductors that extrude insulation.

Beneficial effect of the present invention is:

1, former ground core stranded together with two-phase core is decomposed into several wire conductor; become flat to be arranged in side by side outside two phase cores arranged side by side; make the phase core of bearing electric power transfer be positioned at innermost layer; not only can play similar steel wire armoured effect; can play a very good protection to phase cable core, effectively alleviate and damaged by external force, but also can play shielding action; effectively reduced the electromagnetic interference of electric equipment around, and external electromagnetic interference.

2, phase core, ground wire core conductor all directly drag, and have saved packing material and band, have reduced the waste of material of stranded increase length, have alleviated weight.

3, simultaneously transferring electric power and control signal, can repeatedly move, crooked, vertically use, compact conformation, external diameter is little, is easy to processing and convenient construction.
