  • Patent number: 4812006
    Abstract: A retention mechanism for an optical fiber cable connector which includes a compressible collet having an annular flange adjacent its front end and clamping portions adjacent its rear end. The annular flange includes a shoulder which is retained by an internal recess in the rear body portion of the connector to retain the collet in the connector. The clamping portions include inwardly facing shoulders and outwardly inclined walls. The collet is provided with slots adjacent its front and back ends. When the collet is fully inserted into the rear body portion, the shoulders of the clamping portions firmly clamp against the cable and are retained in their compressed state due to the retention of the inclined walls by the inner walls of the rear body portion.

  • Patent number: 4526438
    Abstract: A resilient alignment sleeve for a fiber optic connector which provides preferential attachment to one of two terminal pins. The sleeve has a relatively thick section extending over about 60 to 70% of the length of the sleeve and a relatively thin section extending over the remainder of the sleeve. The sleeve is retained on the terminal pin which is completely surrounded by the thick section due to increased frictional forces as compared with the thin section.
