Positive locking connector

Abstract

A connector for connecting together two ends of a fluid-carrying line comprises two coupling halves. The female half includes a cylindrical female housing. A support sleeve is concentric with and mounted around part of the female housing, and the forward end is threaded to receive the male half. An actuator sleeve is around the support sleeve. A movable locking member in the form of balls are seated in opening through the support sleeve against the actuator sleeve. A trigger ring inside the support sleeve slides between a blocking position under the balls and an unblocking position releasing the balls. One surface of the actuator sleeve urges the balls against the trigger ring. The threaded forward end of the male half engages the threads of the female half. A nose section on the male half, which extends forward of the threads, engages a trigger actuator ring in the female half. The trigger actuator moves the trigger ring to the unblocking position permitting the balls to move inward to engage groves around the outside of the nose member. Movement of the trigger actuator allows fluid flow when the male member moves. When the two halves are apart the balls seat in pockets on the actuator sleeve so that the actuator and support rotate together. When the balls move inward against the nose, the actuator slides to release the balls from the pockets, which allows the actuator to rotate relative to the support.
