Abstract: An apparatus for providing dual metal to metal seals for sealing tubing encapsulated conductors or hydraulic tubing is disclosed. The apparatus utilizes a unitary, metal seal body that provides an external sealing surface for a first metal to metal seat and an extended portion that energizes a second metal to metal seal. The unitary metal seal body may have a forward end, a midsection, a back end, and an internal passageway proceeding from the back end through the forward end for receiving a tubing encapsulated conductor or hydraulic tubing. The unitary, metal seal body may utilized together in a system with a forward nut, a rear nut, an electrical or tubing connection housing, and three metal ring seals.

Abstract: An electrical connector adapted for mounting to an electrical apparatus used in either high pressure or high temperature, or both high temperature and high pressure, applications. A metal body is provided for mounting to the electrical apparatus with at least one conductor for carrying electricity to or from the electrical apparatus extending therethrough and a thermoplastic jacket is applied over the conductors to the end of the metal body that is subjected to either high pressure or high temperature, or both high temperature and high pressure, for sealing around the conductor. An insulative material is interposed between the metal body and the conductor for sealing around the conductor. In addition to providing two independent internal and two independent external seals, the glass-to-metal seal limits cold-flow (creep) of thermoplastic along the pin and through the metal body.

Abstract: In one embodiment of the present invention, there is provided a female power connector for connecting to a power cable. The power connector is designed to couple a male surface connector to a downhole pumping system. The power connector has a substantially cylindrical piece of pre-molded insulating material, a substantially tubular bushing designed to engage a coupling nut, a coupling nut for engaging a surface connector, and a sleeve. The cylindrical piece has a longitudinal axis, an outside surface defining an outside diameter, a first end, a second end, and a means for creating a fluid tight barrier adjacent to the second end. The cylindrical piece further defines a plurality of substantially circular cavities extending from the first end to the second end parallel to the longitudinal axis. Each channel has an inside surface defining an inside diameter. The bushing engages the coupling nut and the sleeve when the secondary molding is in place.
