Description
Technical field
This utility model is related to air-blowing optical cable, the nonmetallic air-blowing optical cable of particularly outdoor miniature central tubular.
Background technology
Communications optical cable is the prevailing transmission medium of social now various Information Networks.Traditional communications optical cable structural rigidity is big,
Into spring-like after releasing from disk tool, become " C " font after bending, easily cause when laying that pipeline is crowded, pipeline can not be obtained
Use to the limit.In addition, with the continuous development of communication network, original conduit resource cannot meet demand, and
The problems such as newly-built communication pipe faces high cost, destruction periphery traffic and environment again.
Utility model content
The purpose of this utility model is the shortcoming for overcoming prior art, there is provided a kind of light weight, diameter be little and pliability
The nonmetallic air-blowing optical cable of good outdoor miniature central tubular.
The purpose of this utility model is achieved through the following technical solutions：The nonmetallic air-blowing light of the miniature central tubular in outdoor
Cable, it include that oversheath, reinforcement, sleeve pipe, water blocking layer and optical fiber group, described oversheath are coated in the outer rim of reinforcement,
Described reinforcement is coated in the outer rim of sleeve pipe, and is arranged at intervals with the cambered outwards reinforcement in multiple footpaths on reinforcement, described
Reinforcement extend along sleeve pipe, described optical fiber group is located at the interior intracavity of sleeve pipe, and described water blocking layer is arranged on sleeve pipe and optical fiber
In cavity between group.
Described reinforcement is aramid fiber reinforcement, and described reinforcement works out for aramid fiber.
Described water blocking layer is filling paste.
Described water blocking layer by pricking yarn and filling paste is constituted, described prick yarn on the medial wall of sleeve pipe, described
Filling paste is filled in the cavity that pricks between yarn and optical fiber group.
Described water blocking layer is water blocking yarn, and described water blocking yarn claims wire, and the quantity of water blocking yarn is 8 ~ 16, described
Water blocking yarn is uniformly distributed and is close on the medial wall of described sleeve pipe.
This utility model has advantages below：
1st, whole optical cable effectively prevent Radio frequency interference and Electromagnetic Interference without metal structure；
2nd, optical cable total is closely, cable footpath is little, lightweight, be applied to air-blown installation, can effectively prevent sleeve pipe from bouncing back；
3rd, aramid fiber reinforcement and reinforcement is provided with, makes optical cable that there is excellent tensile property and excellent pliability；
4th, water blocking layer is provided with, it is ensured that the water resistance of optical cable, and low cost of manufacture, environmentally safe.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described：
Embodiment one：
As shown in figure 1, the nonmetallic air-blowing optical cable of outdoor miniature central tubular, it include oversheath 1, reinforcement 2, sleeve pipe 3,
Water blocking layer and optical fiber group 5, described oversheath 1 are coated in the outer rim of reinforcement 2, and described oversheath 1 is pe sheath,
Described reinforcement 2 is coated in the outer rim of sleeve pipe 3, and is arranged at intervals with the cambered outwards reinforcement 6 in multiple footpaths on reinforcement 2,
Described reinforcement 6 extends along sleeve pipe 3, and described optical fiber group 5 is located at the interior intracavity of sleeve pipe 3, and described water blocking layer is arranged on set
In cavity between pipe 3 and optical fiber group 5, described oversheath 1, reinforcement 2, sleeve pipe 3, water blocking layer are nonmetal structure, from
And cause optical cable to be effectively prevented Radio frequency interference and Electromagnetic Interference.
In the present embodiment, described reinforcement 2 is aramid fiber reinforcement, and described reinforcement 6 is for aramid fiber is worked out
Cause optical cable that there is excellent tensile property, structural strength and pliability, and reinforcement 6 into, aramid fiber reinforcement and reinforcement 6
Footpath convex, increased the contact area of oversheath 1 and reinforcement 2, so as to improve the switching performance of oversheath 1 and reinforcement 2.
In the present embodiment, described water blocking layer is filling paste 4, has fully ensured that the water resistance of optical cable, and has caused
The packing density of optical fiber group 5 is high, so that the cable footpath of optical cable is little, lightweight, so that optical cable can air-blown installation.
Embodiment two：
In the present embodiment, structure is substantially identical with embodiment one, and unique difference is：As shown in Fig. 2 described resistance
By yarn 7 is pricked and filling paste 4 is constituted, described pricks yarn 7 on the medial wall of sleeve pipe 3 to water layer, and described filling paste 4 is filled in
In the cavity that pricks between yarn 7 and optical fiber group 5, by pricking 4 waterproof of yarn 7 and filling paste, so as to enhance the water resistance of optical cable.
Embodiment three：
In the present embodiment, structure is substantially identical with embodiment one, and unique difference is：As shown in figure 3, described resistance
Water layer is water blocking yarn 8, and described water blocking yarn 8 claims wire, and the quantity of water blocking yarn 8 is 8 ~ 16, uniform point of described water blocking yarn 8
Cloth and it is close on the medial wall of described sleeve pipe 3, therefore the present embodiment, will not be during manufacture and use to week without the need for filling paste
Enclose environment, and the optical cable of the present embodiment is lightweight, cable outer diameter is little, low cost, be readily transported, lay more square
Just.
