Abstract
The utility model provides an improved five-pin coaxial cable, which is characterized in that: at least the external of a conductor for a neutral core is applied with insulation; the neutral core and a grounding core are arranged concentrically on a same circle. Compared with existing five-pin coaxial cable, the utility model has more feasible arrangement, reduces the filler and covering band, has little outside diameter of cable, reduces the usage of materials, lowers down the production cost and weight, which brings much convenience for the engineering of large specification cable. In addition, with stable stranding and excellent round and flatness performance, the utility model will result in no losing and slip during the extruding and engineering process. The neutral core, after insulation processing, is separated from the ground core, which can be easily identified and ensures the use safety.
Description
Technical field
Utility model is the improvement to five core concentric cables, relates in particular to that a kind of external diameter is little, five core concentric cables of more compact structure.
Background technology
Chinese patent 96231635.0 disclosed lv power cables, structure are that the sector conductor of three tape insulations is formed cable core, and ground core and neutral core are divided into two concentric circless and arrange.Its deficiency is: ground core and neutral core are divided into two concentric circless, and space utilization is not compact, have not only increased the outside diameter of cable, take that to lay the space big, and the processing technology complexity, have also increased material usage simultaneously, have increased cable weight.
Chinese patent 97243370.8 disclosed concentric protection conductor low-voltage cables, structure is the corrugation shape phase core of three tape insulations, there is the neutral core of tape insulation at the center, and the uniform phase core of protection concentric conductor periphery is arranged outward.This cable conductor adopts insulation 4 cores, and not only external diameter is bigger, and four-core is stranded easily loose, and insulation is many with material, and cost is big relatively: secondly, and the stupefied core processing technology of watt shape complexity.
Chinese patent 02293982.2 disclosed concentric type five-core cable, employing be that four-core tape insulation conductor is stranded, concentric type conductor layer structure is arranged outward.Four-core tape insulation conductor wherein, be four fan-shaped, and three minor structures greatly.This cable conductor still is a quadrature arrangement, and compact inadequately, external diameter is bigger, and four-core is stranded easily loose, three big minor structures especially, and there is certain clearance in stranded core, and the cable roundness is relatively poor.
Therefore above-mentioned five core concentric cables still have is worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, a kind of compact conformation is provided, strandedly is difficult for the five core concentric cables loose, that roundness good, external diameter is little.
The utility model purpose realizes, main improve be with the neutral core in the five-core cable, core, evenly be arranged in the same circumference of cable with one heart, thereby realize the object of the invention.Specifically, utility model five core concentric cables, the cable core that comprises the stranded fan-shaped phase core composition of three jacket insulation, be arranged in one heart some outer neutral line core conductors of cable core and ground wire core conductor side by side, it is characterized in that each neutral line core conductor has insulation outward at least, neutral line core conductor respectively becomes a segmental arc with the ground wire core conductor, is distributed on one heart on the same circumference.
In order effectively to discern neutral core and ground core, if both all adopt the extruded insulation structure, then two insulation are with colouring discrimination, so that identification; For saving cable cost, utility model ground core can directly adopt bare conductor in addition, therefore only needs neutral line core conductor extruded insulation, can effectively distinguish identification equally.
To form the cable roundness good in order to make, Stability Analysis of Structures, each neutral core external diameter behind the said extruded insulation of utility model is better identical with various places core external diameter.And each neutral core, the core external diameter identical.
Be convenient and make, by the neutral core of cable design, the core cross section, it is divided into some filled circles conductors, promptly neutral core is the filled circles conductor that extrudes insulation; The ground core is solid naked round conductor.Neutral core, core filled circles conductor diameter determine, better be to make it to add behind the extruded insulation that arrangement can be abound with phase core excircle continuously.
Utility model five core concentric cables, can for phase line core, neutral core, the core cross-sectional sizes equate etc. five cored structures, also can be identical for phase line core, neutral core cross-sectional sizes, ground core cross section less " four big one is little " structure, or neutral core, less " three big two the is little " structure in core cross section.According to neutral core, core total cross section separately, arrange diameter by mentioned above principle design concentric circumferences.
Utility model five core concentric cables since with neutral core, core respectively be arranged in a segmental arc, be arranged in one heart side by side on the same circumference of the cable core periphery that the phase core forms.Existing five core concentric cables, winding displacement is more reasonable, tight, has not only saved packing material and band, and can dwindle the outside diameter of cable.The outside diameter of cable is little, takies not only that to lay the space little, and has reduced the consumption of material, has reduced production cost and weight, especially big specification five-core cable construction is brought convenience.Secondly, this structure winding displacement is reasonable, and cable core is stranded stable, roundness, good stability, extrude and process such as construction in can not occur loose, scurry a phenomenon.In addition, the concentric arrangement lay configuration can also play similar steel wire armoured effect, can play a very good protection to the phase cable core, effectively alleviates damaged by external force.Neutral core is distinguished with the ground core by insulation, can be good at identification, has also guaranteed safe in utilization.
Below in conjunction with a representative embodiment, further specify utility model.
Description of drawings
Accompanying drawing is utility model five core concentric cable structural representations.
Embodiment
Embodiment: referring to accompanying drawing, utility model five core concentric cables, the center is by three stranded fan-shaped phase conductor 1 stranded cable cores of forming that respectively extrude by insulation 2, the triple line cable core is outer wrapped or extruded inner cushion layer 3, the neutral core 4 that is extruded with insulation 5 respectively becomes a continuous segmental arc with ground core 6, be distributed on one heart on the outer same circumference of inner cushion layer, extruded sheath 7 outward.Each neutral core 4 and ground core 6 conductors, all adopt the filled circles conductor, diameter is determined, according to neutral core of design and core cross section, ground, can be abound with the inner cushion layer excircle by continuous adjacent arrangement, and neutral core external diameter and bare area core external diameter equal principle are definite behind the extruded insulation.
Sheath can be all kinds of sheaths among the GB2952 " protective coverings of cable " according to the difference of use occasion.
In addition, also can be neutral core, the non-adjacent arrangement of core, just suitably strengthen each neutral core, ground wire core conductor diameter.
