Abstract
The utility model relates to an optical cable trade technical field, in particular to tension -resisting circular optical cable, including optical fiber body, optical fiber body has at least two optic fibre to constitute, optical fiber body ecderon pine sleeve pipe is wrapping up, pine sleeve pipe ecderon tensile layer wrapping up, tensile layer ecderon aramid fiber yarn layer is wrapping up, aramid fiber yarn layer ecderon sheath is wrapping up, tensile layer's surface evenly is provided with a plurality of slat gum strips along the circumference. Using the utility model discloses the time, through set up tensile layer, rubber strip and aramid fiber yarn layer outside optical fiber body, fibercuts, harm appear in the tensile strength and the crooked ability of effectual improvement optical cable when avoiding receiving drawing with the bending, can directly lay or lay in outdoor hidden pipe indoor. The utility model has the advantages of simple structure, it is reasonable to set up, and the cost of manufacture is low.
Description
Technical field
The utility model relates to optical cable industry technology field, particularly a kind of tension circular optical cable.
Background technology
In prior art, the inside cable that wiring system adopts mainly contains GJFJV type and GJFJBV type; ThisThe optical cable of two kinds of structures comprises optical fiber, tight sleeve layer, stiffener, sheath. These two kinds of optical cables in useThere is following shortcoming: 1, GJFJV type optical cable and GJFJBV type optical cable are loose cable structure, lay indoorShi Buneng draws; 2, the stretching resistance of GJFJV type optical cable and GJFJBV type optical cable can only reach 200N,Can only, in indoor use, can not be used for outdoor.
Therefore be necessary to provide a kind of tension circular optical cable.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure,Tension circular optical cable reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of tension circular optical cable described in the utility model, includes optical fiber body, described optical fiber bodyHave two optical fiber compositions at least; The loose sleeve pipe of this external quilt of described optical fiber is wrapped in, and described loose sleeve pipe is outer to be resistedDraw layer to be wrapped in, described tensile layer is outer to be wrapped in by aramid fiber layer, and described aramid fiber layer is outer to be wrapped up by sheath; The outer surface of described tensile layer is provided with some slat gum bars along even circumferential.
Further, the quantity of described rubber strip is two.
Further, the rounded shape of the cross section of described rubber strip.
Further, described aramid fiber layer adopts aramid fiber cotton yarn tape to be made, and aramid fiber cotton yarn tape is wrapped in tensionOn the outer surface of layer and rubber strip.
Further, described tensile layer adopts high-strength tensile fiber to make.
Adopt after said structure, the utility model beneficial effect is: a kind of tension described in the utility modelCircular optical cable, includes optical fiber body, and described optical fiber body has two optical fiber compositions at least; Described optical fiberThe loose sleeve pipe of this external quilt is wrapped in, and described loose sleeve pipe is outer to be wrapped in by tensile layer, and described tensile layer is outer by virtueSynthetic fibre layer is wrapped in, and described aramid fiber layer is outer to be wrapped in by sheath; The outer surface of described tensile layer is along circumferenceEvenly be provided with some slat gum bars.
In the time using the utility model, by tensile layer, rubber strip and aramid yarn being set at optical fiber body outwardLayer, effectively improves tensile property and the crooking ability of optical cable, avoids being subject to stretching and occurs light when bendingFine fracture, infringement; The wiring demand under thunderbolt occasion can be met, existing GJFJV type can be substitutedOptical cable and GJFJBV type optical cable, it both can directly lay or lay in outdoor hidden pipe, tension energy indoorPower is strong, and transmission objective, mechanical performance and environmental performance all meet the requirements. The utlity model has structure letterThe advantages such as list, arranges rationally, and cost of manufacture is low.

Description of reference numerals:
1, optical fiber body; 2, loose sleeve pipe; 3, tensile layer; 4, rubber strip; 5, aramid fiber layer;6, sheath.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of tension circular optical cable described in the utility model, includes optical fiber body 1,Described optical fiber body 1 has two optical fiber compositions at least; The loose sleeve pipe 2 of the outer quilt of described optical fiber body 1 is wrapped in,Described loose sleeve pipe 2 is outer to be wrapped in by tensile layer 3, and described tensile layer 3 is outer to be wrapped in by aramid fiber layer 5,Described aramid fiber layer 5 is outer to be wrapped in by sheath 6; The outer surface of described tensile layer 3 is along even circumferential settingThere are some slat gum bars 4; This optical cable effectively improves tensile property and the crooking ability of optical cable, avoids being subject toWhile stretching with bending, there is fibercuts, infringement.
As the first optimal way of the present utility model, the quantity of described rubber strip 4 is two.
As the first optimal way of the present utility model, the rounded shape of cross section of described rubber strip 4,Improve rubber strip 4 pliabilities.
As the first optimal way of the present utility model, described aramid fiber layer 5 adopts aramid fiber cotton yarn tape to makeForm, aramid fiber cotton yarn tape is wrapped on the outer surface of tensile layer 3 and rubber strip 4.
As the first optimal way of the present utility model, described tensile layer 3 adopts high-strength tensile fiberMake.
In the time using the utility model, by tensile layer, rubber strip and aramid yarn being set at optical fiber body outwardLayer, effectively improves tensile property and the crooking ability of optical cable, avoids being subject to stretching and occurs light when bendingFine fracture, infringement; The wiring demand under thunderbolt occasion can be met, existing GJFJV type can be substitutedOptical cable and GJFJBV type optical cable, it both can directly lay or lay in outdoor hidden pipe, tension energy indoorPower is strong, and transmission objective, mechanical performance and environmental performance all meet the requirements. In addition, this is simple in structure, establishMeter is reasonable, low cost of manufacture.
The above is only preferred embodiments of the present utility model, therefore all according to the utility model patent applicationThe equivalence that structure, feature and principle described in scope done changes or modifies, and is included in the utility modelIn patent claim.
