  • Patent number: 5394494
    Abstract: A fiber optic inline connector includes mating connector bodies each of which has a concentric protrusion at a connector end and a concentric cable passage that extends through the connector body from the connector end to a cable end. The concentric protrusions include a pair of diametrically opposed prongs and a pair of diametrically opposed slots that are orthogonally related to the diametrically opposed prongs so that the slots of each protrusion receive the prongs of the other protrusion to align the cable passages when the connector bodies are mated. The mated connector bodies are locked together by a pair of diametrically opposed stiff lock tongues and a pair of diametrically opposed flexible lock fingers at the connector end of each connector body that are spaced radially outwardly of the respective protrusions.

  • Patent number: 5381501
    Abstract: A fiber optic bundle connector includes a hollow cone having a neck ring and a larger inlet ring at opposite ends of a conical body, a divider disposed in the cone that divides the interior of the cone into several compartments and a terminal block having an end fitted into the inlet ring of the cone. The terminal block has a plurality of terminal cavities that extend through the terminal block to communicate with respective ones of the several compartments. A plurality of jacketed fiber optic cables each having a ferrule attached to its jacket, are inserted through the respective terminal cavities so that their jacket stripped core ends extend into the neck ring of the cone. The neck ring of the cone is deformed by a permanently deformed cinch ring to produce a tightly packed bundle of jacket stripped core ends at a connector end of the fiber optic bundle connector.
