Abstract
The utility model discloses a special coated communication cable. The cable comprises two conductors, wherein each conductor is formed by mixing and twisting three tinned copper wires and four same-diameter galvanized steel wires and is of a 'one plus six' regular arrangement structure, the center of each conductor is provided with one galvanized steel wire, and the three tinned copper wires and the other three same-diameter galvanized steel wires are arranged alternately around the galvanized steel wire in the center. The two conductors are placed in parallel and at intervals, insulating layers and a connecting rib are extruded outside the two conductors at the first attempt to form a cable, the connecting rib is connected between the insulating layers outside the two conductors, and a tensile belt is arranged in the connecting rib. The special coated communication cable is reasonable in structure design, is applicable to wired communication in field battle, radar communication connection and field engineering blasting environments, and has the characteristics of cold resistance, high tensile strength, fire resistance, small outer diameter, convenient wire take-up and play-off, high temperature resistance and flame retardancy.
Description
Technical field:
The utility model relates to telecommunication cable, relates in particular to a kind of extraordinary by multiple telecommunication cable.
Background technology:
Though three bronze medals, four steel constructions that existing insulate line also adopts, but these lines are to adopt bundle strand mode when stranded, and three tinned copper wires and four zinc-coated wires adopt bundle strand mode, not according to the regular arrangement architecture of 1+6, its center is 1 zinc-coated wire, be the zinc-coated wire mode alternately of 3 tinned copper wires and 3 same diameter on every side, add zinc-coated wire than the toughness height of tinned copper wire, its tinned copper wire in bundle strand process can't be in the same place by complete docile bundle with zinc-coated wire, tend to cause the big zinc-coated wire of toughness to carry on the back thigh, jump the shore, conductor is the phenomenon of rounding not.If conductor is rounding not, its insulation must extrude the very thick the thinnest point that insulate that could guarantee and reaches electric, machinery and instructions for use extruding.
As everyone knows, insulate line is to want frequent folding and unfolding on plate, if insulate line is big and heavy, this is very inconvenient in mobile use, and this is one of common insulate line shortcoming.Another shortcoming is that common insulate line mostly is to adopt two to thoroughly do away with edge core pair twist, the outside does not extrude the sheath mode, perhaps adopt two eradication edge cores to be arranged in parallel, the outside extrudes sheath and thoroughly does away with edge core bundle mode together to two, this dual mode is not science very, and for the pair twist mode, two thoroughly do away with the edge cores when stranded, its insulate line is exactly a circle basically, and is totally unfavorable when this lays for flat and narrow space.Another kind of parallelly add the sheath mode just much less, external diameter and weight are unfavorable for that greatly also wild environment uses.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of extraordinary by multiple telecommunication cable, reasonable in design, be applicable to that field operations wire communication, radar communication connect, open-air engineering explosion environment, have cold-resistant, tensile strength is high, fire-resistant, external diameter is little, retractable cable is convenient, high temperature resistant, fire-retardant characteristic.
The technical solution of the utility model is as follows:
Extraordinary by multiple telecommunication cable, comprise two conductors, it is characterized in that: described two conductors mix strand system formation by the zinc-coated wire of 3 tinned copper wires and 4 same diameter, and it is the regular arrangement architecture of 1+6, its center is a zinc-coated wire, be on every side the zinc-coated wire of 3 tinned copper wires and 3 same diameter alternately, described two conductors are parallel and place at the interval and disposable extruded insulation layer, dowel stranding in the outside, dowel is connected between the outer insulating barrier of two conductors, is provided with the tension band in the dowel.
Described extraordinary by multiple telecommunication cable, it is characterized in that: it is the flaming retarding cold resistant polyethylene that described insulating barrier and dowel adopt material.
The utility model has the advantages that:
1, conductor adopts three tinned copper wires and four zinc-coated wires to mix strand, and it is the regular arrangement architecture of 1+6, its center is a zinc-coated wire, be on every side the zinc-coated wire of 3 tinned copper wires and 3 same diameter alternately, this kind structure tinned copper wire can complete docile strand be in the same place with zinc-coated wire, back of the body thigh can not appear in conductor, jumps shore, the not phenomenon of rounding.And insulation does not need to extrude in the process of extruding and very thickly just can reach uniformity, just can satisfy electric, machinery and instructions for use, and its external diameter is little, and is in light weight, adopts the mixing of copper wire and steel wire stranded, and cooperation tension band can improve the advantages such as stretching resistance of cable.
2, polyvinyl chloride insulation and the polyvinyl chloride dowel on two conductors adopts parallel disposable extruding, the outside does not extrude sheath, it is with short production cycle, cost is low, and this kind structure, and the outside diameter of cable is little, can adapt to the narrow space environment, add no sheath, cable has lightweight advantage, adapts to mobile use the in the wild environment especially.
3, insulating barrier and dowel adopt low temperature resistant-40 ℃, high temperature resistant 90 ℃ of flame-retardant polychloroethylene insulation materials, cable has cold-resistant-40 ℃, even reach-45 ℃ low temperature, the environment that high temperature is 90 ℃, and cable has anti-flammability, can adapt to any rugged environment, this is common by the multiple not available advantage of telecommunication cable.
4, two parallel symmetrical structures of conductor, the interior tension band of muscle is connected, it is big to make that cable has stretching resistance, and anti-characteristic of dragging is because the parallel symmetric arrays of two eradication edge cores, do not exist a pine one tight, it is when tension, and two to thoroughly do away with the edge cores stressed evenly, do not exist one stressed big, the stressed little or phenomenon that do not stress, this can give full play to the pull resistance of two core cores.And common pair twist insulate line core, its two pair twist cores are when pair twist, owing to the equipment precision reason, two pair twist cores are asymmetric when pair twist, fully according to two axis that thoroughly do away with the edge cores around arrangement, have the tight phenomenon of a pine one, in this dilatory use in the open air, can cause two to thoroughly do away with edge core discontinuity, can not give full play to the pull resistance of two eradication edge cores, can't adapt to worse environment and use.

Embodiment:
Referring to Fig. 1:
Extraordinary by multiple telecommunication cable, comprise two conductors 1, two conductors 1 are made by the zinc-coated wire 1-2 mixing strand of 3 tinned copper wire 1-1 and 4 same diameter and are constituted, tinned copper wire 1-1 can complete docile strand be in the same place with zinc-coated wire 1-2 in the strand process processed, back of the body thigh can not appear in conductor, jump the shore, the phenomenon of rounding not, and it is the regular arrangement architecture of 1+6, its center is a zinc-coated wire, be on every side the zinc-coated wire of 3 tinned copper wires and 3 same diameter alternately, two conductor 1 parallel and interval placement and disposable extruded insulation layers 2 in the outside, dowel 3 strandings, dowel 3 is connected between two conductors 1 insulating barrier 2 outward, is provided with tension band 4 in the dowel 3.
