Abstract
The utility model provides a three-core composite flat cable which comprises a power cable core, a lapped covering layer, a control cable core and a protecting sleeve layer. The power cable core comprises two parallel phase cable cores directly pulled. The phase cable cores are flat. A plurality of ground cable core conductors are distributed outside the phase cable cores in parallel. The phase cable cores are lapped by the lapped covering layer. The control cable core and the power cable core are directly pulled in parallel. The protecting sleeve layer wraps the control cable core and the power cable core in an extruding mode. Due to the control cable core, the phase cable cores and ground cable cores can be distinguished needless of being recognized. Winding is avoided, and the cable is easy to recognize and convenient to use and maintain.
Description
Technical field
The utility model relates to power cable field, specifically a kind of three 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.
Three core composite cables of the band control cable 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.
Utility model content
The utility model is in order to solve the problem of prior art, 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 three core composite flat cables of processing and convenient construction.
The utility model comprises power cable core, lapping layer, control cable core and restrictive coating, and 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, wrapped by lapping layer; Control cable core and power cable core and directly drag side by side, skin extrudes restrictive coating.
Further improve, it is stranded rear wrapped or extrude and control cable core sheath and form with upper control line core that described control cable core is two or two.
Further improve, described control core is that the outer extruded insulation of control line core conductor forms.
Further improve, described lapping layer is metal screen layer.
Further improve, the external diameter of described control cable core is identical with the height of 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.
The utility model beneficial effect is:
1, cable is flat, highly more circular low, and ground core is divided into some independent conductors, becomes flat to be arranged in side by side outside two phase cores arranged side by side, and length is arranged short simultaneously side by side compared with three cores, reduced to lay space, easy construction.
2, simultaneously transferring electric power and control signal, and independent mutually; Phase 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.
3, owing to there being the existence of controlling cable core, 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model comprises power cable core, lapping layer 5, controls cable core 2 and restrictive coating 3, and described power cable core comprises two phase cores 1 that directly drag side by side, and the outer one-tenth flat of phase core 1 is placed with some ground wire core conductors 4 side by side, wrapped by lapping layer 5.The equidistant gap arrangement of ground wire core conductor 4 or be covered with phase core 1 periphery is identical with the filament diameter size of phase core 1 conductor.
Control cable core 2 and directly drag side by side with power cable core, control cable core 2 and extrude restrictive coating 3 with power cable core skin.Described control cable core 2 external diameters are identical with the height of power cable core, are two or two stranded rear wrapped or extrude and control cable core sheath 7 and form with upper control line core 6, control core 6 and form for the outer extruded insulation of control line core conductor..
