Abstract
An optical fiber connector assembly for coupling an optical fiber cable having optical fibers to an instrument equipped with a light source and a photodetector. The connector assembly has a housing accommodating a pair of ferrules that support the optical fibers. The ferrules have cone-shaped heads and generally flat forward ends. The optical fibers have ends that are flush with the flat ends of the heads. The heads of the ferrules seat into cone-shaped recesses in receptacles mounted on the instrument. The light source and photodetector are aligned with the receptacles so that the light from the light source is transmitted to a first optical fiber and the light from second optical fibers is received by the photodetector. A screw mounted on the housing is threaded into a hole in the instrument to releasably connect the housing to the instrument and locate the heads in alignment with the cone-shaped recesses in the receptacles. Biasing means associated with the ferrules continuously bias and seat the heads in the cone-shaped recesses to maintain the alignment of the ends of the optical fibers with the light source and photodetector.
