Groove on the said groove platform is the V-type groove, and said ring set is through fluid sealant and lock pin body sealing and fixing.Also be provided with the lock ring cover that is used to compress briquetting on the said briquetting.
Concrete, said lock pin body material is pottery, metal, glass or plastics.The material of said optical fiber locking device is pottery, metal, glass or plastics.Lock pin body end face and external diameter grind to form adaptive conventional flexible jumper PC, APC or LC model connector.
The utility model utilizes the high precision inner-pore butt joint of ceramic insertion core to replace existing plastics V-type groove, and it is not only easy for installation, quick, efficient and the cost of registering one's residence is low, possesses good optical property and high reliability simultaneously again.
The utility model uses ceramic insertion core endoporus docking point to replace the advantage of butt joint in the existing V groove to be:
One, the fast rapid-result end assembly of high-performance optical fiber 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, two fiber alignments point is the docking platform that high-precision ceramic insertion core endoporus forms, and the lock pin endoporus is accomplished 1um easily with interior tolerance grade, make two fiber alignments after loss less than 0.1dB.
Four, the lock pin endoporus at fiber alignment place is indeformable under the external force extruding, does not lose efficacy.And the V-type groove that uses organic material is under the extruding of external force extruding or self-contained spring, and easy deformation lost efficacy.
Five, the assembled on site one-time success rate is high, superior performance.
