Description

A kind of four-core flat cable with controlling cable core

Technical field

The invention belongs to field of cables, particularly a kind of four-core flat cable with controlling cable 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 band of prior art is controlled the four-core flat cable of the band control cable core of core, and structure is stranded by controlling cable core and four circular cores that are extruded with insulation conventionally, or four segment conductor-cores are stranded rear stranded with control cable core.Quad core comprises fourth class core that four cross-sectional area of conductor are identical or three cross-sectional area of conductor are large, a 3+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 the four-core composite cable of cable core, and not only cable core poor stability, and material usage is large, has also increased cable weight and cost.As adopt four 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 the four-core composite cable 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 four 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, four-core and control cables cable core are arranged in parallel simultaneously, have increased the width of cable, and structure is not compact.

Summary of the invention

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

A kind of four-core flat cable with controlling cable core disclosed by the invention, comprises and is positioned at the power cable core that band is controlled the four-core flat cable center of cable core, arranges side by side some control core in power cable core periphery, at control core, extrudes sheath outward.

As the further improvement of technique scheme, three phase cores are directly dragged at described power cable core center side by side, the some ground wire core conductors of arranging side by side three phase core peripheries, wrapped lapping layer outside ground wire core conductor.

Another kind as technique scheme improves, the equidistant arrangement of described control core, or it is peripheral to be covered with power cable core.

As the further improvement of technique scheme, controlling between core and total sheath also wrapped one deck twining package tape.

As the another kind of technique scheme, improve, described lapping layer is metal screen layer, or outside described ground wire core conductor wrapped lapping layer again after wrapped metal screen layer.

Another kind as technique scheme improves, and between described three phase cores and ground wire core conductor, is also surrounded with twining package tape.

As the another kind of technique scheme, improve, the conductor that described phase core consists of some monofilament and wrapped insulating barrier 5 at conductor form.

As the further improvement of technique scheme, described ground wire core conductor is evenly distributed.

As further improving again of technique scheme, described ground wire core conductor diameter is identical with filament diameter.

As the further improvement of technique scheme, ground wire core conductor is solid naked round conductor, or for extruding the filled circles conductor of insulation.

Invent a kind of four-core flat cable of controlling cable core with the band of controlling core, transferring electric power and control signal simultaneously, and independent mutually.Phase core, core all directly drag, saved packing material and band, reduced the waste of material of stranded increase length, alleviated weight.Flat structure, can move, bending repeatedly, or vertically uses; As long as any phase core of identification, can differentiate whole cores; Can not be wound around, between cable, easily, working service is convenient in identification.Flat, highly more circular low, and ground core is divided into some independent conductors, and become flat to be arranged in side by side outside three phase cores arranged side by side, length is arranged short simultaneously side by side compared with four-core, reduced to lay space, easy construction.Ground core flat is arranged in outside three phase cores arranged side by side 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.
