摘要： A pair of guide holes for guide pin insertion and one or a plurality of optical fiber positioning holes extending inwardly from the front end surface are formed in a connector ferrule of an optical connector. A chamfer is formed on the opening edge portion of the guide hole of the connector ferrule on the front end surface side thereof. The opening diameter R of the guide hole at the front end surface is preferably 1.0 to 1.5 mm when the front end surface is slant polished at an angle of 8 degrees. Furthermore, the chamfering angle θ of the chamfer is preferably 90 to 150 degrees. Moreover, the average particle size of the filler contained in the connector ferrule is no more than 20 μm. As a result, the surface of the chamfer is comparatively smooth.

摘要： An end-face-side core 5 from which an optical fiber hole forming pin 1 is projected is fastened by a mold to a fiber-side core 10 from which an optical fiber hole forming pin 6 and a cavity forming member (for example, a tape fiber hole forming rectangular body 8) are projected, while the end-face-side core and the fiber-side core are opposed to each other, the cavity forming member being behind the optical fiber hole forming pin 6 and larger than the optical fiber hole forming pin. A resin is injected into a cavity formed in the mold. The mold is opened, the end-face-side core 5 and the fiber-side core 10 are slid in directions in which the end-face-side core and the fiber-side core are separated from each other, and a resin molded product is then taken out.

摘要： A ferrule for optical connector according to the present invention is provided with a fiber positioning hole, a pair of guide holes into which guide pins are inserted, and a connecting end face in which ends of the fiber positioning hole and guide holes open. A chamfer portion equivalent to a part of a surface of a body of revolution is formed at each guide hole on the connecting end face side. Further, the connecting end face is formed at an angle relative to a plane normal to the center axes of the pair of guide holes. In this structure, the slope of the connecting end face can suppress degradation of connection loss, and the provision of the chamfer portions can facilitate insertion of the guide pins, prevent damage of the connecting end face due to the guide pins, and also suppress degradation of connection loss due to the damage.
