Abstract
Abstract A connector assembly is disclosed for crimping onto a fiber optic cable or the like which has one or more single optical fibers and a strength member surrounding the optical fibers. A connector body is provided for receiving the optical fibers of the cable and has a rear end portion over which the strength member of the cable is positionable. The rear end portion of the connector body is provided with one or more annular crimp receiving, generally V-shaped peripheral grooves. A ferrule member is positionable over the grooved rear end portion of the connector body for crimping the strength member between the ferrule member and the connector body. The ferrule member is crimped to have one or more generally V-shaped crimping ribs which are nested in the grooves of the connector body clamping the strength member therebetween. The included angle of each of the V-shaped grooves of the connector body is smaller than that of the V-shaped ribs of the ferrule member so as to increase the number of crimping diameters between the connector body and the ferrule member. In one form of the invention, the rear end portion of the connector body has a transverse abutment surface for engaging the end of a jacket of the fiber optic cable providing an interface between the cable and the connector body.
