Abstract
A fiber optic connector having a deformable rear end adapted to clamp a terminated fiber optic cable in such manner that the fiber and buffer of the cable are capable of limited axial movement within a surrounding sheath. To prevent the buffer from being clamped, a hollow tubular insert is positioned between the buffer and the sheath. The insert includes an enlarged terminal which radially spreads the strength members surrounding the buffer in a uniform distribution and offers protection from subsequent clamping on the outer surface of the sheath. The enlarged terminal also serves as a stop means when inserted between the buffer and the sheath. The rear body element of the connector is provided with internal threads which surround the cable jacket and strength members which, during a clamping operation, causes the sheath and strength members to deform into the threads for superior cable retention.
