Abstract
The present case is hard -pressed bale formula optical cable, includes: the oversheath, it is outermost inoxidizing coating, two -sided plastic -coated steel band, it is located the oversheath inner circle, the steel wire armouring, its evenly distributed in the inlayer of two -sided plastic -coated steel ring, fiber core, it comprises the multifiber, is located the intermediate position of optical cable, PBT pine sleeve pipe, the mode of fiber core parcel is located its skin, hinder water -blocked cable cream, it is in with the spraying mode on the two -sided plastic -coated steel band fill in two -sided plastic -coated steel band with between the PBT pine sleeve pipe, the fine cream that blocks water, it is filled and is in PBT pine cover intraduct. The hard -pressed bale formula optical cable of present case can improve the compressive capacity of optical cable effectively, can absorb with the influence that stops most external mechanical forces and environmental factor optic fibre in to the optical cable, therefore have outdoor optical cable advantage.
Description
Technical field
The utility model relates to optical cable field, is specifically related to a kind of pipe core hard-pressed bale formula optical cable.
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, may there is sewage and mouse etc. in pipeline, cable lifetime is in the presence of a harsh environment seriously affected by environment simultaneously.Simultaneously because the optical fiber dense degree in this kind of optical cable is not high, branch capability is little, can not adapt to repeatedly the requirement of branch, and increasing along with fiber number, its external diameter increases rapidly, fixedly brings difficulty to laying, solution also not good at present.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure hard-pressed bale formula optical cable that is simple, that easily realize.
For achieving the above object, the utility model is achieved through the following technical solutions:
Hard-pressed bale formula optical cable, comprising:
Oversheath 1, it is outermost protective layer;
Double plastic-coated steel band 2, it is positioned at described oversheath inner ring;
Wire armoring 3, it is uniformly distributed in the internal layer of described double plastic-coated steel ring,
Fiber cores 6, it is made up of multifiber, is positioned at the centre position of described optical cable;
PBT Loose tube 4, is positioned at by the mode that described fiber cores is wrapped up in its skin;
Block water cable cream 5, and it is filled between described double plastic-coated steel band and described PBT Loose tube in the mode be sprayed on described double plastic-coated steel band;
Block water fine cream 7, and it is inner that it is filled in described PBT Loose tube.
Preferably, described hard-pressed bale formula optical cable, wherein, described oversheath is medium density polyethylene, i.e. MDPE protective layer.
Preferably, described hard-pressed bale formula optical cable, wherein, described wire armoring is made up of even number bar armouring wire.
Preferably, described hard-pressed bale formula optical cable, wherein, described fiber cores is made up of 12 to 144 optical fiber.
Preferably, described hard-pressed bale formula optical cable, wherein, described PBT pine pipe box material is polybutylene terephthalate.
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, directly on steel band, spray one deck sprays special cable cream, and every 1 meter of length can fill about half meter, save most ointment, and play good block-water effect.Outside sub-optical cable unit, be provided with even number bar armouring wire, 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; The hard-pressed bale formula optical cable of this case can improve the anti-pressure ability of optical cable effectively, 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hard-pressed bale formula optical cable described in the utility model one embodiment.
Wherein, 1-oversheath, 2-double plastic-coated steel band, 3-wire armoring, 4-PBT Loose tube, 5-blocks water cable cream, 6-fiber cores, and 7-blocks water fine cream.

Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
Hard-pressed bale formula optical cable, refers to accompanying drawing 1, comprising:
Oversheath 1, it is outermost protective layer;
Double plastic-coated steel band 2, it is positioned at described oversheath inner ring;
Wire armoring 3, it is uniformly distributed in the internal layer of described double plastic-coated steel ring, and wire armoring can bear mechanical tensile forces;
Fiber cores 6, it is made up of multifiber, is positioned at the centre position of described optical cable;
PBT Loose tube 4, is positioned at by the mode that described fiber cores is wrapped up in its skin;
Block water cable cream 5, and it is filled between described double plastic-coated steel band and described PBT Loose tube in the mode be sprayed on described double plastic-coated steel band;
Block water fine cream 7, and it is inner that it is filled in described PBT Loose tube.
Further, described oversheath is medium density polyethylene, i.e. MDPE protective layer.
Further, described wire armoring is made up of even number bar armouring wire.
Further, described fiber cores is made up of 12 to 144 optical fiber.
Further, described PBT pine pipe box material is polybutylene terephthalate.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
