Abstract
The present case is an optical cable of high resistance to pressure, includes: the oversheath, it is outermost inoxidizing coating, two -sided plastic -coated steel band, it is located the oversheath inner circle, the inner sheath, it is located the inlayer of two -sided plastic -coated steel band, double coated aluminium strip, it is located the inlayer of inner sheath, the optical fiber ribbon, it comprises the multifiber, PBT loose tube will the mode of optical fiber ribbon parcel is located its skin, the fine cream that blocks water, it is filled and is in in the PBT loose tube, metal reinforcement, it is located the center of optical cable, it is individual that little gasket for packing, its quantity are the even number, fills to be in in the middle of the PBT loose tube, hinder water -blocked cable cream, it is in with the spraying the last mode of double coated aluminium strip fill in in the double coated aluminium strip. The cable configuration of present case can absorb with the influence that stops most external mechanical forces and environmental factor optic fibre in to the optical cable, therefore have the advantage of outdoor optical cable.
Description
Technical field
The utility model relates to optical cable, particularly relates to a kind of optical cable of high resistance to pressure.
Background technology
The technology that usual outdoor filled type communications optical cable is identical, only in the difference of filling cable cream part, ointment pump or other factice for filling parts can not be used, spraying cable cream device is installed, be sprayed on steel, aluminium strip by special for spraying cable cream before steel, aluminium strip enter preforming tool, each rice sprays half meter of cable cream; If alone spraying can not play block-water effect, can use before spraying and fill cable cream, and use vulcanite scraper cream mould all to be struck off by cable cream all around cable core, only stay the cable cream at the stranded place of cable core, re-use spraying afterwards.Purposes due to inside cable determine the resistance to tension of optical cable poor, there is no stop water yet, be not suitable for laying use in pipeline, sewage and mouse etc. may be there is in pipeline simultaneously, cable lifetime is in the presence of a harsh environment seriously affected by environment, and once run into the larger situation of pressure ratio, general optical cable is not resistance to slightly large pressure long term.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model be to provide a kind of structure simply, the optical cable of durable for a long time high resistance to pressure.
For achieving the above object, the utility model is achieved through the following technical solutions:
An optical cable for high resistance to pressure, comprising:
Oversheath 1, it is outermost protective layer;
Double plastic-coated steel band 2, it is positioned at described oversheath inner ring;
Inner sheath 3, it is positioned at the internal layer of described double plastic-coated steel band;
Double plastic-coated aluminium strip 4, it is positioned at the internal layer of described inner sheath;
Fibre ribbon 6, it is made up of multifiber;
PBT pine pipe box 5, is positioned at by the mode that described fibre ribbon wraps up in its skin;
Block water fine cream 7, and it is filled in described PBT pine pipe box;
Metal reinforcement 8, it is positioned at the center of described optical cable;
Little gasket for packing 9, its quantity is even number, is filled in the middle of described PBT pine pipe box;
Block water cable cream 10, and it is filled in described double plastic-coated aluminium strip in the mode be sprayed on described double plastic-coated aluminium strip.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described oversheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described inner sheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described fibre ribbon is made up of 12 to 144 optical fiber arrangement rectangular in form.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described PBT pine pipe box material is polybutylene terephthalate.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described metal reinforcement material is stainless steel.
Preferably, described withstand voltage ruggedized fiber optic cable, wherein, described little gasket for packing is that solid PE restricts.
The beneficial effects of the utility model: the utility model structure is simple, under the prerequisite using jet printing type optical cable not affect at optical cable permeability performance, effectively can save great amount of cost, do not use and fill cable cream or use a small amount of filling cable cream, directly on steel aluminium strip, spray one deck sprays special cable cream, can save a large amount of starting material every year, and the block-water effect spraying cable cream is better than the block-water effect of filled type cable cream; Adopt and be respectively equipped with double plastic-coated steel band and double plastic-coated aluminium strip at oversheath and internal sleeve internal layer, spraying waterproof cable cream between some sub-optical cable units, effectively prevent the infringement that the various factors such as sewage and mouse causes optical cable, ensure that the serviceable life of optical cable, be highly suitable for construction usage in pipeline; Several little gasket for packings are also provided with in the position of other sky except sub-optical cable, by the comparison consolidation that optical cable inside is filled, effectively can improve the anti-pressure ability of optical cable, this structure Absorbable rod and stop most of external mechanical power and environmental factor on the impact of optical cable inner fiber, thus has outdoor optical cable advantage; Simultaneously because optical fiber is belt like combination, substantially increase optical fiber dense degree, adapt to the requirement that fiber cable network expansion optical distribution cable branch increases; Less optical cable external dimensions and square-section make it easy between building, building and internal channel Jian He building, building internal channel lay fixing and should not slide, and so just can ensure that optical cable has outdoor optical cable advantage and is suitable in features such as outdoor laid lay again.
