The utility model content
The purpose of this utility model provides a kind of pegging graft and conveniently satisfies the bearing accuracy and the low joints of optical fibre of production cost again, and a kind of optical fiber connector plug and socket also are provided simultaneously.
For achieving the above object, the utility model adopts following technical scheme: a kind of fiber connector socket, comprise the orientation direction pin that is arranged at this socket inserted terminal, described orientation direction pin comprises the pin body of cylindricality, one end of pin body is connected on the socket, the other end is a boot segment, and the rear end of boot segment is provided with and is used for the locating ring platform that cooperates with pilot hole location on the plug, and the axial length of described boot segment is greater than the axial length of locating ring platform.
Described locating ring platform is provided with chamfering towards the end face periphery of pin body boot segment.
The two ends of described orientation direction pin pin body are equipped with chamfering.
A kind of optical fiber connector plug, the inserted terminal of this plug is provided with the orientation direction pin-and-hole, described orientation direction pin-and-hole is a stepped hole, and this stepped hole comprises inner bullport and the pilot hole that is connected by the ledge structure transition with bullport, and the axial depth of bullport is greater than the axial depth of pilot hole.
The step transition place of described stepped hole is provided with chamfering.
A kind of joints of optical fibre, comprise plug and socket, the inserted terminal of socket is provided with the orientation direction pin, the inserted terminal of plug is provided with the orientation direction pin-and-hole that matches with the orientation direction pin, described orientation direction pin comprises the pin body of cylindricality, and an end of pin body is connected on the socket, and the other end is a boot segment, the rear end of boot segment is provided with and is used for the locating ring platform that cooperates with pilot hole location on the plug, and the axial length of described boot segment is greater than the axial length of locating ring platform; Described orientation direction pin-and-hole is the stepped hole that cooperates with described orientation direction pin.
The step transition place of described stepped hole is provided with chamfering.
Described locating ring platform is provided with chamfering towards the end face periphery of pin body boot segment.
The two ends of described orientation direction pin pin body are equipped with chamfering.
The joints of optical fibre of such scheme, adopt the mode channeling conduct location of ladder pin during its plug and socket inserting, be that the ladder pin is the pin that a stage casing has the ring platform, the ring platform is divided into the boot segment of front end and the construction section of rear end with pin, the pin-and-hole that cooperates with the ladder pin is a shoulder hole, the boot segment of ladder pin cooperates with the path hole section guiding of shoulder hole, the ring platform of ladder pin cooperates with the section location, hole, big footpath of shoulder hole, after adopting this structure, because boot segment does not relate to the problem of hi-Fix, therefore can adopt the mode of the low slightly clearance fit of size, and only need to adopt high-precision size can satisfy the connection accuracy requirement of the joints of optical fibre in cooperation place, ring platform location, because boot segment is a clearance fit, the grafting of more convenient like this plug and socket, and it no longer adopts whole high-precision processing, has reduced processing cost.In addition, the axial length of boot segment is greater than the axial length of ring platform, could guarantee that like this boot segment well plays guiding function after, encircle platform and just enter into hole, the big footpath of stepped hole section and accurately locate.
