Diameter is small, saves material, at low cost, light-weight, and unique interior hexagonal structure design can avoid the slippage between every layer of sheath, and
And drag performance with excellent tension.
In order to solve the above-mentioned technical problem, the utility model provides interior hexagonal ADSS communications optical cables, including cable core and packet
Wrap up in the sheath of cable core;The cable core includes the nonmetallic strengthening core being arranged from inside to outside, microbeam pipe;The microbeam pipe is more,
It include multifiber in the every microbeam pipe;The sheath includes inner sheath and oversheath;The inner sheath is regular hexagon
Sheath, the oversheath are interior hexagonal sheath and are fitted closely with the inner sheath.
Further, the inner sheath includes non-metal reinforced layer and the aramid yarn that wraps up the non-metal reinforced layer
Layer.
Further, the aramid yarn layer outer wrapping water blocking layer.
Further, it is provided with tear rope in the water blocking layer.
Further, the nonmetallic strengthening core is KFRP strengthening cores.
Compared with prior art, the utility model has the beneficial effects that:
1, optical cable uses a kind of special interior hexagonal structure in the utility model, and this design is so that between each layer sheath
More closely, structure is more firm, can avoid the slippage between every layer of sheath for contact.
2, in the utility model relative to traditional circular optical cable, greatly save material, not only reduce expense cost, but also make
It is more light and handy to obtain optical cable.
3, the utility model uses micro- bundle tube structure, and cable core is more compact, and optic cable diameter is small.
4, the nonmetallic strengthening core of the utility model use so that the optical cable have good tensile property.
5, there are certain the air gaps between the utility model microbeam pipe and its housing, enhance the flexible of the optical cable
Degree, has good anti-cushion performance.
6, the utility model waterstop and aramid yarn are used in combination so that the optical cable can waterproof it is high pressure resistant.
7, it is also surrounded by tear rope in the utility model waterstop, resists the ability that pulls with good, and energy absorbing cable makes
With the heat distributed in the process.

The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment
Referring to Fig.1, the utility model discloses a kind of interior hexagonal ADSS communications optical cables, by cable core, inner sheath, oversheath group
At.Inner sheath is positive hexagonal sheath, and oversheath is interior hexagonal sheath.Cable core includes optical fiber 1, KFRP strengthening cores 2 and microbeam pipe 3.
Wherein, KFRP strengthening cores are hexagon, and six face of side wall bears against the microbeam pipe of six roots of sensation package fiber optic bundle, every pipe 12 in microbeam pipe
Core, totally 6 pipe, microbeam pipe outside diameter are 1.3 ± 0.05mm or so, and using LSZH sheaths, spatial arrangement is close.Hexagon sheath includes
Non-metal reinforced layer 4, aramid yarn layer 5, waterstop 6.Microbeam pipe can be fixed and be wrapped up by hexagon non-metal reinforced layer 4, microbeam
Pipe is not easy play displacement.Coat aramid yarn 5 and the waterstop 6 for capableing of waterproof successively outside non-metal reinforced layer 4.This hexagon
Structure is relative to traditional circular configuration, since the presence of six corner angle makes the package between each layer sheath more closely,
Avoid the slippage between every layer of sheath.It is additionally provided with tearing rope 8 in waterstop, can be dragged with tension and absorbing cable uses process
In the heat that distributes.Oversheath 7 is in interior hexagon, and the outer wall of inner wall and inner sheath tightly fastens, and makes oversheath and inner sheath
It fits closely contact to be not easy to slip, the utility model uses HDPE oversheaths.
ADSS communications optical cables are subjected to dead weight and external load, therefore to optical cable itself as All Dielectric self-support
Weight demands it is high.The present embodiment use very cleverly in hexagonal construction the contact of every layer of sheath can not only be made more tight
Close, cable core capacity bigger can also save material, mitigate the weight of optical cable.Such as the external protection structural representation that Fig. 2 is cable core
Figure.Positive hexagonal external protection 9 and traditional round external protection 10 in comparison diagram, it can be seen that positive hexagonal external protection 9 is more
To save material, and optical cable is as a kind of multilayered structure, and in the case where every layer of protective layer saves material, overall weight is just significantly
It reduces.ADSS communications optical cables in the present embodiment are more light and handy, cost reduction, and weight is small.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new
Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest range consistent with novel point.
