An electrical connector system, particularly one that connects armored electrical cables for oil wells through an upper surface connector that is mated to a feed-through mandrel, automatically operates a circuit breaker in the main power circuit as the upper connector is unmated from the mandrel. A pair of relay (R) wires are carried with the main power conductors through the upper connector. A set of relay (R) contacts, preferably pins and sockets, electrically connect the R wires between the connector and the mandrel. The contacts in the mandrel are wired together. Unmating the connector withdraws the R pins from their sockets which trips a relay or otherwise operates the main circuit breaker. Power (P) contacts, preferably pins and sockets, for the main power conductors are longer than the R pins so that power in the main conductors is shut off before arcing can occur. Preferably this "quick disconnect" relay circuit is used in conjunction with an improved lip seal formed on the mating end of a resilient insulating body filling the connector.

A field-attachable electrical connector splices the conductors of two armored cables without hand soldering. The connector has a rigid hollow housing with axial passages at both ends that receive and locate the cables. Insulating end supports locate and seal the conductors projecting from the outer armor jacket. A sealing connector, also formed of an insulating material, bridges the end supports and surrounds the stripped ends of the conductors of both cables and a pin contact secured on each conductor's end. A locking contact socket member with two axially oriented oppositely directed sockets is secured in a passage of the seal connector between a pair of the stripped ends. A spring clip carried on the pin contact mates with a recess in the socket connector to secure each pin contact in a reliable electrical connection within an associated socket. Each socket connector has a gas impermeable wall between its two sockets. The housing has a compact cross-sectional profile and is configured internally to be in a close-fitting relationship with the end supports and the sealing connection between the end supports.

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.

An aircraft ground power cable system having field-replaceable nose and contact components. The connector body is at one end integrally molded to a ground cable sheath and at the other end is provided with internal fixed contacts to which a replaceable nose section may be threadably secured. Weather- and water-tight seals are provided about the peripheral junction of the nose section and the connector body as well as about the sealing screws which secure the nose to the body. Also provided on the connector body in sealed relationship are a replaceable switch plate and switches mounted on that plate. The replaceable nose section includes replacement contacts for engaging mating contacts on the aircraft.

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.

A cable connector system includes a first set of contacts fixed in a housing and a second set of contacts fixed in a replaceable nose section. The second set of contacts is configured to mate with a standard power receptacle, for example, on an aircraft. Advantageously, a third set of contacts is fixed in an intermediate section, wherein the third set of contacts is adapted to mate the first set of contacts with the second set of contacts.
