Methods for manufacturing and coupling movable optical fiber connector

The invention discloses a method for manufacturing a movable optical fiber connector, a process, and a method for coupling the movable optical fiber connector. After the surface of a completely cut optical fiber is subjected to melting spherical surface treatment, the optical fiber is fixed by a mechanical or cementing device arranged on the rear part of a ceramic positioning sleeve, the cut surface of the optical fiber is higher than the surface of the ceramic positioning sleeve, protrusion amount is equal to the deformation of the optical fiber, the optical fiber is radially centered in a positioning hole on the front part of the ceramic positioning sleeve, the optical fiber in the ceramic positioning sleeve before coupling is in a free state, and the optical fiber in the free state is subjected to elastic bending deformation and retracts to the ceramic positioning sleeve during coupling, so that the end face of the optical fiber is elastically coupled, and the movable optical fiber connector is reliably bu
