The right four-core composite cable of band control core of prior art, 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 length of cable, and structure is not compact.
Summary of the invention
The present invention overcomes the shortcoming that prior art exists, and provides a kind of signal to disturb little, simultaneously transferring electric power and control signal, 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 right four-core composite flat cable of core.
Disclosed by the invention a kind of with controlling the right four-core composite flat cable of core, this cable is flat structure, three phase cores are directly dragged at the center of described cable side by side, the outer wrapped band of phase core, band arrange side by side outward some ground cores with at least one pair of control core pair, cable outermost layer extrudes oversheath.
Further improve, the phase conductor that described phase core consists of some monofilament and wrapped insulating barrier in phase conductor form.
Further improve, described control core is to controlling cores, wrappedly control the metal knitted screen outside cores and the thin sheath being extruded in outside metal knitted screen forms at 2 by 2 that directly drag.
Further improve, described ground core with control core equity apart from gap arrangement or be covered with outside band.
Further improve, this cable be phase core, core cross-sectional sizes equate etc. quadrature arrangement or equate " three large one little " structure less with core cross section, ground for phase core cross-sectional sizes.
Beneficial effect of the present invention is:
Compared with prior art, of the present invention a kind of with controlling the right four-core composite flat cable of core, transferring electric power and control signal simultaneously, and have mutually metal screen layer to shield, independent mutually, signal disturbs little; 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, with control core to together with 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 with control core to together with; flat is arranged in outside three phase cores arranged side by side side by side, makes 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.
