US 2004/0105625 A1 · Optical fiber connector

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.

Dependent claims

An optical fiber connector attached to an end of an optical fiber and used with an adapter in an optical connection, said optical fiber connector comprising:

a housing attachable to and removable from said adapter;
a ferrule through which a cladding portion at said end of said optical fiber is inserted and supported, said ferrule being housed slidably toward an axial direction in said housing in a rotatable manner in an assembly step;
a compression coil spring mounted in said housing and biasing said ferrule along an axis and toward said end of said optical fiber;
and
a rotation-restricting slide mechanism disposed toward a base end of said housing, said rotation-restricting slide mechanism restricting rotation of said ferrule relative to said housing and allowing a sliding motion along said axis.
