Abstract
An apparatus is provided for use in molding a ferrule which must hold an optical fiber cable so the optical fiber lies precisely concentric with the cylindrical outside surface of the forward portion of the ferrule. A corepin which lies within a mold to form a ferrule cavity between them, has a rearward end held to the mold and a forward end which must be held precisely concentric with the inside surface of the ferrule cavity. A bushing of clover leaf design is positioned in the mold cavity, and has three radially-extending arms that precisely center the forward end of the corepin, while leaving spaces between the arms through which plastic can flow during the molding of the ferrule. The radially-outer arms of the bushing are tied by tying portions whose radially inside surfaces form an interrupted cylindrical outside surface of the ferrule.
