Abstract: The invention provides exemplary connector systems and methods for their use. In an exemplary embodiment, a connector system is provided which comprises a first and a second connector. In turn, each connector comprises a connector body having a central axis. Each connector further includes a latch spring that is generally aligned with the central axis and includes an offset oriented generally toward the central axis, a lead-in ramp and an inset notch which is oriented generally toward the central axis on a side of the connector body generally opposite to the latch spring. The first and the second connectors may be connected by abutting the connector bodies, with each latch spring being received over the lead-in ramp on the abutting connector and engaging with the inset notch on the abutting connector.

Abstract: The invention provides a connector system and methods for attaching a first and second connector. Each connector includes an elongate connector body and a coupling nut rotatably coupled about the connector body. Each coupling nut includes a center plate and a pair of latch arms, with each arm having a groove therein to define a tooth at a distal end of each arm. The arms are substantially parallel to the connector body. Each connector further includes at least one resilient member which resists movement of the arms away from their parallel orientation relative to the elongate body. The first and second connectors may be connected by abutting the connector bodies and rotating the coupling nuts so that the grooves and teeth of corresponding arms mate with each other.

Abstract: An environmentally safe wellhead for wells utilizing electrical submersible pumps which includes an internally tapered casing head into which an externally tapered tubing hanger is closely fitted and sealed. Openings are formed through the tubing hanger parallel to its axis and production tubing is threaded into one of the openings. The power cable for the pump is enclosed in a feedthrough connector disposed and sealed in another of the openings. Tightly fitted metal parts are used and O-ring seals are disposed between the tapered walls of the casing head and hanger as well as between the wall of the opening and the feedthrough connector for the power cable. The feedthrough connector has a metal shell and a separable threadably connected cap member, the interior of which is substantially filled with resilient high dielectric constant material bonded to insulating layers disposed on contacts for the conductors of the cable.

Abstract: An attachable aircraft ground connector which includes a connector body insertable in the input power socket of a parked aircraft, the connector body having a replaceable nose and contacts at one end and a grommet mounted at the other end, the grommet being detachably retained in place by removable screws and the body and grommet having complementary resilient elements so disposed and cooperating as to maintain a sealing relationship between the two under the urging of said removable screws. Within the grommet, a peripheral clamp is provided to hold in place an input power line.
