Abstract
A connector assembly connects a hub connector to a wellhead housing by utilizing a collet. The collet has an upper internal projection that engages the hub connector and a lower internal projection that engages the flange on the wellhead housing. An actuator ring moves the collet from an unlocked to a locked position, the actuator ring moving axially. A drive nut, when rotated, will move the actuator ring downward. Load screws extending through the drive nut force the actuator ring further downward after the drive nut has reached its lower position. Release pins extending through the actuator ring, when rotated inward, will pry against a release surface to move the actuator ring upward relative to the drive nut.
