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： The ferrule 7 of the optical connector in accordance with the present invention has an optical fiber inserting portion 11 extending inward from an optical connection opening 10 formed in the nose surface 9, thereby projecting the end portion of an optical fiber 8 from the optical connection opening 10 in the nose surface 9. The nose surface 9 has a first flat portion 15 and a second flat portion 14. The second flat portion 14 extends while including the optical connection opening 10 therein. The first flat portion 15 extends so as to project ahead of the second flat portion 14. The end surface of the optical fiber 8 is disposed within the same plane as the first flat portion

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.
