Description
?
Technical field
The present invention relates to electric wire field, especially a kind of flexure type five core flat cables.
Background technology
Five-core cable in prior art, conventionally structure is all that five circular cores that are extruded with insulation are stranded, or four segment conductor-cores and a circular core stranded.Five-core cable core comprises 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.Five stranded particularly five 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 five-core cable, not only cable core poor stability, and material usage is large, has also increased cable weight and cost.As adopt five 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 five-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 five-core cable electromagnetic interference of structure is larger conventionally.
The prior art circular configuration outside diameter of cable is large, in wire casing, lays, and especially needs multi-cable simultaneously during overlapping laying, and takies that to lay space still very large, has limited use in small space; 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 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 five core flat cables of processing and convenient construction.
For solving above technical problem, a kind of flexure type five core flat cables of the present invention, this cable is flat structure, cable center 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, the outer wrapped twining package tape of ground wire core conductor and neutral core, twining package tape extrudes sheath outward.
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 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 the side in phase core periphery, and both quantity is identical.
