A plug single body 03 is assembled in the floating shell 01, and an optical cable fixing sleeve 02 is used for the optical cable to penetrate so that the optical fiber in the optical cable can be inserted into the plug single body 03. The floating shell 01 is provided with a plug floating spring 05, the front end of the plug floating spring 05 is pressed on the tail of the plug single body 03, the rear end of the plug floating spring 05 is pressed on the front end of the optical cable fixing sleeve 02, and the plug single body 03 and the rear shell 02 can float in the front-rear direction relatively through self elastic deformation. The plug single body 03 is provided with a locking elastic sheet 04 which can be clamped into a socket of the adaptive connector to realize locking of the insertion core parts of the two connectors.
The existing optical fiber connector faces the need of waterproof and dustproof, so the structure of the optical fiber connector shown in fig. 1 and 2 is improved by the technical staff, that is, a protective shell is added on the optical fiber connector, and a relatively sealed environment is formed by using the protective shell to resist the influence of the external environment on the core part of the optical fiber connector. As shown in fig. 3, the optical fiber connector further includes a housing assembly 06, the housing assembly 06 includes a cylindrical housing 07 and a locking cap 08 fitted around the cylindrical housing 06, the floating housing 01 of the optical fiber connector is accommodated in the cylindrical housing 07, and the optical cable fixing sleeve 02 is fixed relative to the cylindrical housing 07. The cylindrical shell 07 is provided with a blocking structure for blocking the locking cap 08 in the backward direction, the inner side of the locking cap 08 is provided with an inner step, and the inner step is positioned in front of the blocking structure; a spring 09 is disposed at the outer periphery of the cylindrical housing 07 and inside the locking cap 08, and two ends of the spring 09 respectively act on the inner step and the stopping structure to provide a forward elastic force to the locking cap 08. The steel ball is arranged at the inserting position of the shell of the adaptive connector, the ball groove is arranged at the inserting matching position of the cylindrical shell 07, when the two connectors are inserted and matched, the steel ball on the adaptive connector can be embedded into the ball groove on the cylindrical shell 07 to realize the locking of the two connectors, and meanwhile, the locking cap 08 bears the elastic supporting force of the spring 09 and can tightly press the cylindrical shell 07 and the adaptive connector shell inwards in the radial direction, so that the matching of the steel ball and the ball groove is tighter to ensure the connection stability of the cylindrical shell and the adaptive connector shell.

The optical fiber connector 10 is further provided with an unlocking component, so that the ferrule assembly and the housing assembly in the two connectors can be unlocked in one unlocking operation. Specifically, the unlocking member in this embodiment is a seesaw structure, and mainly includes a hinge base disposed on the support housing 16, the hinge base is rotatably assembled with a rotating shaft 171 extending in a direction perpendicular to the insertion direction, a front force arm 172 is connected to an upper side of an outer peripheral surface of the rotating shaft 171, and the front force arm 172 is a slender sheet structure and can swing downward with the rotation of the rotating shaft 171. The preceding arm of force 172 extends along the fore-and-aft direction, and its front end is arranged in the top of locking shell fragment 151 in LC fiber optic plug 15, and when pivot 171 rotated and drove preceding arm of force 172 and swung down, the front end of preceding arm of force 172 constitutes and presses the end, can push down locking shell fragment 151, and locking shell fragment 151 swings down can remove the locking relation of self and adapter connector mesochite casing, and when the force application was not put on locking shell fragment 151 to the preceding arm of force 172, locking shell fragment 151 can keep at locking state.
A rear force arm 173 cantilevered backward is connected to the lower side of the outer peripheral surface of the rotating shaft 171, the rear force arm 173 is a thin and long sheet structure and has a direction opposite to the cantilevered direction of the front force arm 172, one end of the rear force arm 173, which is far away from the front force arm 172, is linked with the cylindrical shell 11, and the rotating shaft 171 can be driven to rotate when the rear force arm 173 is driven by the cylindrical shell 11. Specifically, the front end of the rear arm 173 is connected to the outer peripheral surface of the rotary shaft 171, and the rear end of the rear arm 173 is provided with a long hole extending in the front-rear direction.
Correspondingly, an unlocking button 14 for realizing the linkage of the cylindrical shell 11 and the rear arm 173 is fixedly arranged on the inner wall surface of the cylindrical shell 11. Wherein the release button 14 comprises a fixed ring and a hooking button extending from the inner side of the fixed ring. An annular groove is formed in the inner wall surface of the cylindrical shell 11, a fixing ring of the unlocking buckle 14 is embedded into the annular groove to fix the whole unlocking buckle 14 and the cylindrical shell 11, and the hook buckle can extend into a long hole of the rear force arm 173 and can be in stop fit with the rear hole wall of the long hole in the inserting direction, so that the rear force arm 173 is driven to move backwards, and the rotating shaft 171 is driven to rotate.
Because the floating spring is arranged in the ferrule assembly, the LC fiber optic plug 15 can move relative to the cylindrical shell 11 and the locking cap 12 in the front-rear direction, when the cylindrical shell 11 moves back to unlock the shell of the adapter 20, the unlocking buckle 14 fixedly connected with the cylindrical shell can be driven to move back, the unlocking buckle 14 drives the rear force arm 173 to move so as to rotate the rotating shaft 171, and the rear force arm 173 is opposite to the overhanging direction of the front force arm 172 and is positioned on two opposite sides of the rotating shaft 171, so the rear force arm 173 moves to rotate the rotating shaft 171, the rotating shaft 171 rotates to drive the front force arm 172 to press the locking elastic sheet 151 downwards, and the cocked locking elastic sheet 151 can be unlocked from the adapter after being pressed downwards.
Specifically, when it is necessary to unlock the optical fiber connector 10 and the mating connector 20 in the present embodiment, as shown in fig. 6 and 7, the operator first pushes the locking cap 12 to move back toward the mating end (i.e., move back), at which time the locking spring 13 sleeved on the cylindrical housing 11 will contract and generate a force to the cylindrical housing 11 to retreat back toward the mating connector 20 by abutting with the outer convex edge of the cylindrical housing 11. Meanwhile, the cylindrical shell 11 and the LC optical fiber plug 15 therein are in a relatively floating state, and the relative positions of the cylindrical shell 11 and the LC optical fiber plug 15 in the cylindrical shell are not fixed in the front-rear direction, and at this time, the ferrule assembly in the optical fiber connector 10 and the ferrule portion in the adapter connector 20 are still in a connected state, the cylindrical shell 11 will move backward relative to the ferrule assembly, the release buckle 14 fixedly connected with the cylindrical shell 11 will also move backward, the rear force arm 173 at this time is driven by the release buckle 14 to move backward, and then the rotating shaft 171 will be driven to rotate backward, after the rotating shaft 171 rotates, the front force arm 172 opposite to the rear force arm 173 will swing downward along with the rotating shaft 171, so as to press down the tilted locking elastic sheet 151, after the locking elastic sheet 151 is pressed, the locking state of the ferrule portion in the adapter connector will be released, and in the whole unlocking process, only the operation of the ferrule portion of the housing assembly, the operation is more convenient.
