ABSTRACT:
A connector employs a segmented nut and a seal. The connector includes a housing with a bore having a bowl in it. A shaft extends through the bore, the shaft having exterior threads. Segments are carried on the bowl and move between a upper retracted position to an engaged position. A drive system slides the segments down and rotates them until threads from the segments align with the shaft threads. Each segment has a resilient seal which also has a portion of a thread for sealing against the threads of the shaft. An actuator will move the seals from an outboard position which occurs during rotation to a sealing position after rotation.
