Abstract:
An optical fiber connector for terminating a fiber cable having a buffered optical fiber therein wherein an end portion of the fiber has been stripped of its buffer, said connector comprising:a ferrule having a receiving end, a terminating end, and a tapered ferrule bore therein having a larger diameter at said receiving end than at said terminating end; a barrel having a barrel bore therein, said barrel being arranged and configured to receive at one end said receiving end of said ferrule wherein said bores of said barrel and said ferrule are axially aligned, said barrel bore forming a receiving sleeve at its second end; an insert slidably disposed within said ferrule bore, said insert having a receiving end for receiving a buffered portion of the optical fiber and a support end for supporting the stripped portion of the optical fiber and an insert bore extruding therethrough, said insert bore having a tapered portion in the region of said receiving end forming a stop against which the buffer portion of the optical fiber bears when inserted in said insert bore; said support end of said insert having tapered first resilient gripping members for gripping the unbuffered portion of the optical fiber, the taper of said first gripping member substantially matching the taper of said ferrule tapered bore; said receiving end of said insert having second resilient gripping members for gripping the buffered portion of the optical fiber when deformed; and said insert member having an external portion at said receiving end adapted to bear against said receiving sleeve portion of said barrel for deforming said second resilient gripping members when said insert is moved tranlationally toward said support end, said barrel, said insert, and said ferrule being longitudinally displacable relative to each other.
