A connector assembly includes a pin connector for receipt by a box connector. The pin connector features a neck portion having external threads; the box connector features a collar portion having internal threads, generally complementary for meshing with the external threads. The connectors may be threadedly joined together by longitudinally inserting the pin connector into the box connector, whereupon the two connectors are mutually sealed at two locations on opposite sides of the internal and external threads to define, with the threads, an annular region. Application of fluid pressure to the annular region may radially expand the region to permit further insertion of the pin connector into the box connector to mutually align the internal and external threads. Release of the fluid pressure permits mutual meshing between the threads to threadedly connect the pin and box connectors. The connector assembly may be released by like application of fluid pressure to radially expand the annular region, or by mutual rotation between the pin and box connectors, to disengage the meshing between the internal and external threads. |
