FERRULE HOLDER FOR FIBER OPTIC CONNECTOR

An improved fiber optic connector of the type in which a fiber supporting ferrule (15) is slidably and resiliently biased independently of the surrounding load-bearing parts of the connector so that forces applied to the fiber optic cable jacket are not transmitted to the ferrule (15) and supported fiber to interrupt communications then in progress. In one of the embodiments, the needle of a syringe is inserted into a positioning tube (16) which confines an adhesive to the needed area, and prevents wicking of the adhesive to surrounding areas where it might interfere with the sliding action of the ferrule (15). It also wipes the needle as the syringe is withdrawn. A rear body element (13) provided with internal threads (50) which surround the cable jacket, which during a crimping operation, causes the jacket to deform into the threads for superior cable retention. Alternate embodiments include a rear body having means for engaging a sheath of a fiber optic cable, key means, and crimping operations with collet-like fingers.
