Optical fiber connector and cable assembly

The utility model provides an optical fiber connector and a cable assembly, relates to the technical field of communication, and aims to solve the technical problem that an optical fiber connector is poor in use effect. The optical fiber connector provided by the utility model comprises an insertion core base and a sleeve. The ferrule base is provided with a through hole for an optical fiber to penetrate through, the peripheral surface of the ferrule base is provided with a first abutting surface, the first abutting surface and the axis form an included angle, the inner wall of the sleeve is provided with a first limiting surface, and the first limiting surface and the first abutting surface form an included angle with the axis; the first abutting surface abuts against the first limiting surface and is used for preventing the insertion core base from moving relative to the sleeve in the first direction and allowing the sleeve and the insertion core base to rotate relative to each other around the axis. In the optical fiber connector provided by the utility model, position limiting between the insertion core base and the sleeve is realized through mutual abutting between the first abutting surface and the first limiting surface, the sleeve and the insertion core base can be allowed to generate relative rotation at any angle around the axis, and the optical fiber connector has better use convenience.
