Abstract
The present invention provides an optical fiber connector for making high-precision optical connections between optical fibers. During assembly, a ferrule is rotationally adjusted around its axis 360° without stepping. The assembly, including this rotational adjustment, can be performed easily and reliably.An optical fiber connector 1 comprises: a housing 2 that can be mounted on and removed from an adapter A; a ferrule 3 through which a cladding portion F1 at the end of an optical fiber F is inserted is rotatably housed in the housing 2 so that it can move along the axial direction; a compression coil spring 4 biasing the ferrule 3 in the axial end direction; and a rotation-restricting slide mechanism 5 that restricts rotation of the ferrule 3 relative to the housing 2 at the base-end side of the housing 3 and that allows the ferrule 3 to slide in the axial direction.
