Tubular connector
This patent describes a tubular connector. It comprises: a first tubular member; a second tubular member; a sleeve slidably mounted on the exterior of one of the tubular members and extending toward the other of the tubular members, at least a portion of the sleeve being spaced from one of the tubular members to form a pressure chamber and including sealing means between the sleeve and one of the tubular members at the upper and lower ends of the spaced portion to seal the pressure chamber, a port extending through one of the tubular members into the pressure chamber to supply pressure fluid thereto to move the sleeve between latched and released positions, a plurality of latching fingers carried within the interior of the sleeve and having shoulders for clamping engagement with the tubular members to latch them together in abutting end-to-end relationship when the sleeve is moved axially to latched position, initial axial latching movement of the sleeve carrying the latching fingers axially with respect to the tubular members to place the shoulders into position surrounding the ends of the tubular members, means for restraining the axial movement of the latching fingers with the sleeve after they are in surrounding position to the ends of the tubular members, mating cam surfaces on the interior of the sleeve and on the exterior of the latching fingers coacting to move the latching fingers into clamping engagement with the ends of the tubular members during the axial movement of the sleeve subsequent to the restraining of the axial movement of the latching fingers, and means for isolating the interior of the sleeve and the latching means for the environment surrounding the tubular members when they are latched together.
