Description
Technical field
The utility model belongs to field of cables, particularly a kind of four-core composite flat cable.
Background technology
Along with the develop rapidly of 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 entirety, to realize highly intelligentized requirement.
The four-core composite cable of the band control cable 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.The four-core composite cable of this structure band control cable core, 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 complexity, 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, waste material, increase 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, transport 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 when overlapping laying, take that to lay space still very large, in small space, limited use; Secondly, many round cables when laying installation, are easily wound around between cable together, and identification difficulty, working service trouble; Again, round cable core identification 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 in the time of vertical use, the stack of cable lower end is born and is discharged the twisting resistance transmitting above, therefore therefore twisting resistance maximum can be distorted distortion, bulge, broken skin until the heart yearn that fractures after the use several months.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 of flat cable of employing, 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.
Utility model content
The utility model is to overcome the shortcoming that prior art exists, transferring electric power and control signal simultaneously of a kind of while is provided, compact conformation, external diameter is little, and can repeatedly move, bending, the four-core four-core composite flat cable that vertically uses, be easy to the band control cable core of processing and convenient construction.
The disclosed a kind of four-core composite flat cable of the utility model, comprises the power cable core directly dragging side by side and controls cable core; Three phase cores are directly dragged at described power cable core center side by side, and the some ground wire core conductors of arranging side by side three phase core peripheries, extrude total sheath outward at ground wire core conductor.
As the further improvement of technique scheme, the conductor that described phase core is made up of some monofilament and wrapped insulating barrier at conductor form.
Another kind as technique scheme improves, and described ground wire core conductor is evenly distributed.
As the further improvement of technique scheme, described ground wire core conductor diameter is identical with filament diameter.
Another kind as technique scheme improves, and ground wire core conductor is solid naked round conductor, or for extruding the filled circles conductor of insulation.
Another kind as technique scheme improves, and described control cable core is controlled the stranded rear wrapped metal screen layer of core by some, and outermost extrudes sheath again and forms.
As the further improvement of technique scheme, described control core quantity is more than 2 or 2.
As the further improvement of technique scheme, described control core is made up of control line core conductor and the insulating barrier that is extruded in control line core conductor outside.
As the further improvement of technique scheme, the external diameter of described control cable core is identical with the height of power cable core.
The disclosed a kind of four-core composite flat cable of the utility model, transferring electric power and control signal simultaneously, and independent mutually.Phase core, core, control cable 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; Owing to there being the existence of cable core of control, without identification phase core, core, can differentiate whole phase cores, core, 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, width 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 reduce controlling cable core and the electromagnetic interference of electric equipment around, and external electromagnetic interference.
