The present invention relates to an optical connector and an optical connector assembling method allowing simplification of assembly, improvement of reliability, and lower prices. The optical connector comprises a connector plug for holding a coated optical fiber and a connector socket for holding a coated optical fiber. The connector plug has a fiber holding portion disposed in a plug housing, and a fiber inserting hole is provided in the fiber holding portion. A fiber deflection space for allowing deflection of the coated optical fiber, when the coated optical fibers are butted, is provided in the plug housing. The connector socket has a fiber holding portion disposed in a socket housing, and a fiber inserting hole is provided in the fiber holding portion. A fiber deflection space for allowing deflection of the coated optical fiber, when the coated optical fibers are butted, is provided in the socket housing.

Optical connector and optical connector assembling method

An optical connector ferrule molding diefor molding an optical connector ferrule having a plurality of optical fiber holes comprises an upper diea lower dieand an intermediate diewhereas the intermediate diecomprises a plurality of optical fiber hole forming pinsfor forming optical fiber holes. The lower dieis provided with a protrusionfor forming a window hole of the optical connector ferrule, whereas the optical fiber hole forming pinsprojecting from the intermediate dieare secured by through holespenetrating through the protrusionand V-grooves
