Description
Technical field
The present invention relates to a kind of joints of optical fibre, especially a kind of multi-fiber connector.
Background technology
Optical fiber is used for broadband application more and more, comprising voice, video recording and data transmission.Consequently, Networks of Fiber Communications has comprised the interconnection point of many interconnection multifibers.Networks of Fiber Communications also comprises many connecting terminals; Be used for the optical fiber communication service extension to the user; Develop into " Fiber To The Curb " (FTTC), " optical fiber is to enterprise " (FTTB), " fiber-to-the-subscriber " (FTTH), " optical fiber is to the house " (FTTP), the general designation " FTTx ".
The joints of optical fibre; Be optical fiber with optical fiber between carry out the device that detachable (activity) is connected; It gets up the accurate butt joint of two end faces of optical fiber; Go so that the luminous energy of launching fiber output can be coupled to receive in the optical fiber to greatest extent, and make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have influenced reliability and each item performance of optical transmission system.The joints of optical fibre are widely used, and are various in style, are divided into single core and multicore (like MT-RJ) by fiber number; Can be divided into by bindiny mechanism's difference and to be threaded, push-in type bindiny mechanism, bayonet coupling mechanism, to slip into formula bindiny mechanism and push self-locking and connect.
Be to satisfy at a high speed and the needs of high-capacity optical fiber communication system middle-high density and high efficiency interconnection wiring, multi-core fiber is used more and more widely, and a plurality of optical fiber components are promptly arranged in the plug, from comprising 4,8,12 optical fiber, in addition more.At present; Existing multi-fiber connector; Like Chinese utility model patent disclosed " a kind of plug self-locking type fast fibre connector " (CN202141834U); Be made up of plug, socket, cable fixer, plug body, jack housing, said plug head becomes the joints of optical fibre with the socket front end to insert group; Be provided with a plurality of ferrule assemblies in the said plug, each ferrule assembly is made up of ceramic insertion core and lock pin tailstock, sheathed successively spring of lock pin tailstock and spring backstop, and spring backstop and spring offset, and the front end of ceramic insertion core is provided with a ceramic sleeve; Said socket front end be provided with said plug in the corresponding shoulder hole of ferrule assembly, ferrule assembly is housed in the shoulder hole, sheathed successively spring and spring backstop on the ferrule assembly, spring backstop and spring offset.Wherein, the setting of spring for the single ceramic lock pin provides the axial float amount when docking, is guaranteed the reliability that connects.
Yet, because the ferrule assembly quantity that comprises in the multi-core fiber is more and more, when plug docks with socket; Each ferrule assembly can cause unavoidably that in mutual butt joint the butt joint accuracy between the lock pin is not good; Thereby cause ferrule assembly under out-of-alignment situation, apply the grafting acting force, become hard grafting; Be prone to cause the insertion loss and the return loss of ceramic insertion core, finally have influence on the data transmission performance after the butt joint.
Summary of the invention
