Abstract
The invention discloses a three-core flat cable with a small outer diameter. The cable is of a flat structure, two paratactic phase wire cores are arranged in the center of the cable, a circle of ground wire core conductors are arranged outside the phase wire cores side by side, a wrapping tape is wrapped around the ground wire core conductors, and a protecting sleeve is wrapped around the wrapping tape in an extruded mode. The three-core flat cable has the advantages of being capable of being repeatedly moved, bent and vertically used, compact in structure, small in diameter and easy to machine, achieving convenient construction and the like.
Description
?
Technical field
The present invention relates to electric wire field, the three core flat cables that especially a kind of external diameter is little.
Background technology
Three-core cable in prior art, structure is all that three circular cores that are extruded with insulation are stranded conventionally, or three segment conductor-cores are stranded.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.Three stranded particularly three circular cores of unequal section of circular core are stranded, 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 three-core cable, 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 the three-core cable 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, transportation difficulty, and takies that to lay space large.Besides, the three-core cable electromagnetic interference of the common structure of three cores is larger.
Chinese patent ZL 200620073748.5 has announced a kind of three-core cable, adopts circular shape concentric structure, has dwindled the outside diameter of cable, the waste of material that has reduced stranded increase length, has alleviated weight, not only reduces 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 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, provide a kind of and can repeatedly move, crooked, vertically use, compact conformation, external diameter is little, is easy to three core flat cables of processing and convenient construction.
For solving above technical problem, the three core flat cables that a kind of external diameter of the present invention is little, this cable is flat structure, cable center is provided with two phase cores arranged side by side, at the phase core some ground wire core conductors of a circle of arranging side by side outward, the outer wrapped twining package tape of ground wire core conductor, twining package tape extrudes sheath outward.
Described phase core by phase conductor and wrapped outside phase conductor twining package tape form.
Described phase conductor is by some stranded the forming of monofilament.
The described equidistant gap arrangement of ground wire core conductor or be covered with at phase core peripherally, its diameter is identical with the filament diameter of formation phase conductor.
Described ground wire core conductor is solid naked round conductor or is the filled circles conductor that extrudes insulation.
Beneficial effect of the present invention is:
Compared with prior art, the three core flat cables that external diameter of the present invention is 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, and become flat to be arranged in side by side outside two phase cores arranged side by side, length is arranged short simultaneously side by side compared with three cores, reduced to lay space, easy construction; Ground core flat is arranged in outside two 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, the three core flat cables that a kind of external diameter of the present invention is little, this cable is flat structure, cable center is provided with two phase cores 1 arranged side by side, at the outer some ground wire core conductors 4 of a circle of arranging side by side of phase core 1, the outer wrapped twining package tape 3 of ground wire core conductor, twining package tape extrudes sheath 5 outward.Described phase core is by phase conductor 2 and wrappedly at the outer twining package tape 3 of phase conductor 2, form; Described phase conductor 2 forms by some monofilament 6 are stranded; The described equidistant gap arrangement of ground wire core conductor 4 or be covered with at phase core peripherally, its diameter is identical with monofilament 6 diameters of formation phase conductor; Described ground wire core conductor 4 is for solid naked round conductor or for extruding the filled circles conductor of insulation.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection scope of the present invention.
