Abstract:
1. A fiber optic connector comprising: a molded, one-piece plug main body defining a central longitudinal axis that extends from a proximal end to a distal end of the plug main body, the plug main body including one or more exterior surfaces defining an exterior boundary of the plug main body that extends around the central longitudinal axis, the plug main body also including one or more interior surfaces defining an interior boundary of the plug main body that extends around the central longitudinal axis, the interior boundary defining a central longitudinal passage that extends through the plug main body along the central longitudinal axis, the exterior boundary of the plug main body defining a groove that extends around the central longitudinal axis, and the interior boundary of the plug main body defining a shoulder facing in a proximal direction; a cover that attaches to the proximal end of the one-piece plug main body, wherein a strength member of a fiber optic cable can be secured between the cover and the proximal end of the one-piece plug main body; a ferrule assembly including a ferrule member positioned at least partially within the central longitudinal passage, the ferrule member being aligned along the central longitudinal axis, the ferrule assembly also including a spring that biases the ferrule member in a distal direction, and the ferrule assembly abutting the shoulder of the interior boundary of the plug main body; an external sealing member mounted within the groove, the external sealing member including at least a portion that extends radially outwardly beyond the exterior boundary of the plug main body, the external sealing member defining a maximum outer cross-dimension less than or equal to 15 millimeters; an external fastener for securing the plug main body within a fiber optic adapter; a sleeve positioned over at least a portion of the cover and the proximal end of the one-piece plug main body, the sleeve having a proximal portion positioned proximally with respect to a proximal end of the external fastener and a distal portion positioned distally with respect to the proximal end of the external fastener; and a heat shrink layer positioned between the sleeve and the fastener.
