Description

A kind of five core composite flat cables

Technical field

The utility model relates to electric wire field, especially a kind of five core composite flat cables.

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.

Five core composite cables of the band control cable core of prior art, structure is stranded by controlling cable core and five circular cores that are extruded with insulation conventionally, or five segment conductor-cores are stranded rear stranded with control cable core.Five core power cables comprise five five cores such as grade that cross-sectional area of conductor is identical, " four large one little " core that " three large two little " core that three cross-sectional area of conductor are large, two cross-sectional area of conductor are little or four cross-sectional area of conductor be large, 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 five 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 segment conductor-core lay configuration, 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 five 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 five 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, five cores and control cables cable core are arranged in parallel simultaneously, have increased the length of cable, and structure is not compact.

Utility model content

The utility model is to overcome the shortcoming that prior art exists, and transferring electric power and control signal simultaneously of a kind of while is provided, and can repeatedly move, crooked, vertically use, compact conformation, external diameter is little, is easy to five core composite flat cables of processing and convenient construction.

For solving above technical problem, a kind of five core composite flat cables described in the utility model, this cable is flat structure, is by power cable core, to extrude oversheath with the side by side straight drag and drop postpone of control cable core to form; The center of power cable core is provided with three phase cores arranged side by side, at phase core arrange side by side outward some ground wire core conductors of half-turn and some neutral cores of half-turn, and the outer wrapped twining package tape of ground wire core conductor and neutral core, twining package tape extrudes sheath outward; After described control cable core is stranded by some control cores, extruding sheath forms.

Described phase core by phase conductor and wrapped outside phase conductor twining package tape form.

Described neutral core is by neutral conductor and be extruded in neutral conductor external insulation layer and form.

Described control core is more than 2 or 2, and it forms by controlling conductor and being extruded in the insulating barrier of controlling outside conductor.

Described phase conductor is by some stranded the forming of monofilament.

Described ground wire core conductor is with the equidistant gap arrangement of neutral core or be covered with in the both sides of phase core periphery, and both quantity is identical.

Described ground wire core conductor is identical with the diameter of the monofilament of formation ground wire core conductor with the diameter of neutral core.

Described ground wire core conductor is solid naked round conductor or is the filled circles conductor that extrudes insulation.

The utility model beneficial effect is:

Compared with prior art, a kind of five core composite flat cables described in the utility model, simultaneously transferring electric power and control signal, and independent mutually; Phase core, neutral core, core, control cable core and 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 controlling cable core, without identification phase core, neutral core, core, can differentiate whole phase cores, neutral core, core; Can not be wound around, between cable, easily, working service is convenient in identification.Flat, highly more circular low, and by neutral core, core be divided into some independent conductors, 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 five cores, reduced to lay space, easy construction.Neutral core, core flat be arranged in side by side outside three 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 controlling cable core and the electromagnetic interference of electric equipment around, and external electromagnetic interference.
