Abstract

The utility model provides an optical cable of tough nature, includes: the oversheath, it is medium density polyethylene, MDPE inoxidizing coating promptly, two -sided plastic -coated steel band, it is located the oversheath inner circle, fiber core, it comprises the multifiber, PBT loose tube will the mode of fiber core parcel is located its skin, the fine cream that blocks water, it is filled and is in in the PBT loose tube, the nylon oversheath, it is located the skin of oversheath, hinder water -blocked cable cream, it is in with the spraying mode on the two -sided plastic -coated steel band is filled wherein, metal reinforcement, it is located the center of optical cable, the gasket for packing, its with PBT loose tube centers on around the metal reinforcement, stable structure is arranged into in the combination. The present case has set up the nylon oversheath at the skin of oversheath, has prevented the harm that various factorss such as sewage and mouse led to the fact the optical cable effectively, has guaranteed the life of optical cable, especially adapted in the pipeline construction use, toughness and life all strengthen greatly.

Description

A kind of optical cable of obdurability

Technical field

The utility model relates to optical cable, particularly relates to a kind of optical cable of obdurability.

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 one deck sheath of the prior art can not prevent the situations such as mouse baits for a long time.

Utility model content

For overcoming the deficiencies in the prior art, the purpose of this utility model is the optical cable providing a kind of obdurability, saves cost while being intended to anti-adverse environment.

For achieving the above object, the utility model is achieved through the following technical solutions:

An optical cable for obdurability, comprising:

Oversheath 1, it is medium density polyethylene, i.e. MDPE protective layer;

Double plastic-coated steel band 2, it is positioned at described oversheath inner ring;

Fiber cores 5, it is made up of multifiber;

PBT pine pipe box 4, is positioned at by the mode that described fiber cores is wrapped up in its skin;

Block water fine cream 3, and it is filled in described PBT pine pipe box;

Nylon outer sheath 6, it is positioned at the skin of described oversheath;

Block water cable cream 7, and it fills wherein in the mode be sprayed on described double plastic-coated steel band;

Metal reinforcement 8, it is positioned at the center of described optical cable;

Gasket for packing 9, itself and described PBT pine pipe box are centered around the surrounding of described metal reinforcement, and combination collocation becomes rock-steady structure.

Preferably, the optical cable of described obdurability, wherein, described fiber cores is made up of 12 to 144 optical fiber.

Preferably, the optical cable of described obdurability, wherein, described PBT pine pipe box material is polybutylene terephthalate.

Preferably, the optical cable of described obdurability, wherein, described metal reinforcement material is stainless steel.

Preferably, the optical cable of described obdurability, wherein, described nylon outer sheath material is nylon material.

Preferably, the optical cable of described obdurability, wherein, described 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, 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; Gasket for packing and PBT pine pipe box is adopted to be centered around the surrounding of described metal reinforcement, combination collocation becomes rock-steady structure, and be provided with nylon outer sheath at the skin of oversheath, 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, toughness and serviceable life strengthen all greatly.

Accompanying drawing explanation

Fig. 1 is the structural representation of the optical cable of the obdurability described in the utility model one embodiment.

Wherein, 1-oversheath, 2-double plastic-coated steel band, 3-blocks water fine cream, 4-PBT pine pipe box, 5-fiber cores, 6-nylon outer sheath, and 7-blocks water cable cream, 8-metal reinforcement, 9-gasket for packing.

Embodiment

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.

An optical cable for obdurability, refers to accompanying drawing 1, comprising:

Oversheath 1, it is medium density polyethylene, i.e. MDPE protective layer;

Fiber cores 5, it is made up of multifiber;

Block water fine cream 3, and it is filled in described PBT pine pipe box;

Nylon outer sheath 6, it is positioned at the skin of described oversheath;

Further, described fiber cores is made up of 12 to 144 optical fiber.

Further, described PBT pine pipe box material is polybutylene terephthalate.

Further, described metal reinforcement material is stainless steel.

Further, described nylon outer sheath material is nylon material.

Further, described gasket for packing is that solid PE restricts.

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.
