Patent ID: 8500340

Claim:
An optical ferrule assembly, the optical ferrule assembly comprising: a ferrule body, the ferrule body including an optical fiber loading hole extending therethough in a longitudinal direction; a notch part formed in the ferrule body, the notch part including a flat surface including the optical fiber loading hole; a retainer arranged in the notch part, the retainer including a lower abutting surface opposing to the flat surface, an inclined abutting surface formed on one end side of the lower abutting surface, an outer peripheral surface opposite the lower abutting surface, and a conical surface formed at the rear end of the retainer proximate the outer peripheral surface, the outer peripheral surface having a semi-cylindrical shape; and an annular member fit on an outer periphery of the ferrule body; wherein: the inclined abutting surface is opposed to the flat surface, and the lower abutting surface is inclined to the flat surface and separated from the flat surface, when the annular member is brought into contact with a portion of the outer peripheral surface; and the inclined abutting surface is inclined to the flat surface and separated from the flat surface, and the lower abutting surface is opposed to the flat surface, when the annular member is brought into contact with the whole of the outer peripheral surface.
