Abstract
An adapter assembly for optical fiber connectors comprises a base having a profiled axial bore, a receptacle housing and a receptacle. The receptacle housing has at least one four sided compartment structure extending forwared from the base and open at a front receiving end. Within the housing is the receptacle comprising a socket extending from the adapter base and having bore a axially alinged with the bore of the base to form an extension thereof and. The receptacle is adapted to receive an alignment ferrule of an optical fiber connector. The receptacle further has two catch pieces of cantilever form extending from the base parallel to and on opposing sides of the longitudinal axis of the socket. The catch pieces terminate in protrusions and lip structures for intermating with a push-pull type of optical fiber connector. Each lip structure of each catch piece has at least three inwardly beveled surfaces leading from the lip edge of each structure forward toward the interconnection with the push-pull optical fiber connector to facilitate lead-in of the connector during connection to the adapter assembly.
