The invention relates to the technical field of optical fiber connectors, in particular to an optical fiber connector. The optical fiber connector comprises a ceramic ferrule shell, a ceramic ferrule, a spring and a shell body; in the process of assembly, fixing glue is dripped in the hole of the ceramic ferrule, the ceramic ferrule shell is fastened with the shell body, a processed optical fiber then sequentially runs through the shell body, and finally, the fiber core of the front end of the optical fiber is inserted in the hole in the ceramic ferrule. After the structure is adopted, the structure and the assembling method of the optical fiber connector optimize the conventional assembling steps, save the assembling time, and increase the production efficiency, so that assembly becomes simpler.
