Description
Technical field
The present invention relates to a kind of rapid-result soon end assembly of field-installed closed type optical fiber that is used for, assembly is held in the fast short-term training of field-installed closed type optical fiber that is used for that is specifically related to various model built-in types.
Background technology
At present, along with the develop rapidly of Fibre Optical Communication Technology, the PON access technology has become the main solution that global FTTH (Fiber to the home) popularizes in an all-round way.Yet, insert at this last kilometer and to install, how to accomplish to register one's residence that cost is low, easy for installation, quickness and high efficiency, it is very crucial possessing good optical property, high unfailing performance simultaneously again.
Install for the access of FTTH (Fiber to the home), traditional optical fiber fusion welding technology is because its cost is high, receive the restriction in place, installation personnel to need professional training etc. former thereby can't obtain large-area popularization when installing.The fast rapid-result end of optical fiber assembly has become the optimal selection scheme that present FTTH inserts with its advantage such as easy for installation, quick, efficient.
Assembly is held in the fast short-term training of built-in type that has common in existing fast rapid-result end assembly; It is a pre-buried optical fiber in the ceramic insertion core endoporus; One end forms the termination of docking with normal connector with ceramic insertion core behind grinding and polishing; The other end then exposes certain-length and guarantees that end face is smooth, then bared end optical fiber is installed in the V-type groove, and the V-type groove is equipped with corresponding optical fiber briquetting and is used for fixing the butt joint of going into optical fiber and pre-buried optical fiber outward; In the V-type groove, preset the coupling gel during butt joint in advance, eliminate the Fei Nier reflection when being used for fiber alignment.The existence and the quality of coupling gel directly influence the fiber alignment effect.The loss of coupling gel or pollution will directly cause butt joint to be lost efficacy.There is not hermetic fiber docking point function in the design of existing fast rapid-result end assembly, not protection coupling gel, the coupling gel runs off and pollutes in various rugged surroundings, has caused the fiber alignment inefficacy.Portioned product will lose efficacy about 1 year under arms at present, and the coupling gel runs off or pollutes is main cause.
Summary of the invention
For solving prior art problems, the purpose of this invention is to provide a kind of fast rapid-result end assembly of field-installed closed type optical fiber that is used for, possess good optical performance and high reliability.The present invention has solved inefficacy of coupling gel or the bad problem that the fast rapid-result end assembly of present optical fiber exists fully.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of fast rapid-result end of field-installed closed type optical fiber assembly that is used for comprises the lock pin body and is positioned at the endoporus of lock pin body that pre-buried optical fiber and incoming fiber optic are inserted by lock pin body two ends respectively; Offer until the coupling gel that exposes endoporus on the said lock pin body and preset mouth; Wherein, said lock pin body on an end of incoming fiber optic, closely be socketed with one have in the sealing shroud of shaft through-hole, said sealing shroud is used for sealing coupling gel and presets mouth; Incoming fiber optic gets into lock pin body endoporus by middle shaft through-hole, and presets effected with pre-buried optical fiber at the coupling gel and dock.
In this programme, two optical fiber preset the effected butt joint at the coupling gel, through sealing shroud docking point are realized sealing, prevent the matching fluid pollution, run off or volatilization.
Said sealing shroud also comprises is located at the terminal micropore of middle shaft through-hole, and incoming fiber optic is pierced in the middle shaft through-hole by micropore; Said sealing shroud also comprises is located at the terminal V-type groove platform of micropore, and incoming fiber optic is pierced in the micropore by V-type groove platform.
Said sealing shroud material is plastics or metal; Said lock pin body is stupalith, metal material, glass material or organic material.
Said coupling gel presets mouth and is groove-like, and has one or more; Said coupling gel presets mouth and is platform-like.Said sealing shroud carries out sealing and fixing through sealing glue and lock pin body.
Compared with prior art, the invention has the advantages that:
One, high performance optical fiber quick connector core possesses good optical property and high reliability.
Two, in whole making flow process, pre-buried fiber optic protection is difficult for being damaged in the inside of lock pin body, has guaranteed its quality and cost in factory process.And present optical fiber quick connector all to be pre-buried optical fiber expose, when assembling, fracture easily, it is impaired or be stained with booty to occur fiber end face simultaneously, causes butt joint to be lost efficacy.
Three, being used for fixing two fiber alignments point is the tube bank of high-precision ceramic insertion core endoporus, and endoporus is accomplished 1um easily with interior tolerance grade, make two fiber alignments after loss less than 0.1dB.And the V-type groove major part at existing quick coupler fiber alignment place all adopts organic material, this material easy ageing, distortion, and also precision is not high.Some quick coupler adopts metal material to process, and same precision is difficult to reach requirement, and cost is very high.
Four, the pre-buried optical fiber of whole quick coupler is all in the inside of lock pin body, and all material is consistent, is not acted upon by temperature changes, and the reliability of entire product is guaranteed.
Five, docking point is realized sealing, prevents the matching fluid pollution, runs off or volatilization.The optical fiber quick connector part of installing and using at present will lose efficacy about 1 year, and the coupling gel runs off, volatilizees or receive pollution is main cause.The part Company products has been taked the finedraw encapsulation scheme, runs off or pollutes and lost efficacy but cause mating the gel volatilization through long-time this aging of product distortion of being on active service.
