A high pressure and temperature, hermetically sealed bulkhead connector with pin and socket contacts for use in logging tools is described. The bulkhead connector comprises (a) one or more contact(s) placed within one or more channels wherein the channels provide a clearance path between contact(s) and bulkhead body and travel at least a partial longitudinal distance between proximal and distal ends. The contact(s) reside in the channel(s) and include at least; an optional movement limiter section, one central elongated section, and one fixed section where the contact(s) is attached to the bulkhead body at the distal end. The body correctly positions respective ends of the contact so that the body secures contact(s) to be parallel to each other and the contact(s) have terminal ends for connection. This arrangement provides at least one pivotable, pliable, free floating contact extending away from the fixed distal end of the bulkhead body.

The present invention provides a modular electrical feedthrough system for use in offshore and top-side electrical submersible pump (ESP) installations. A modular electrical connection system includes a stab receptacle assembly for mating with a stab plug assembly and a compliance mount. The stab plug assembly includes stab plugs and guide funnels adapted to guide the stab receptacles into a mating position with the stab plugs. The compliance mount compensates for physical misalignment between stab receptacles and stab plugs. A tubing hanger assembly forms a pressure barrier at a production bore by use of a tubing hanger penetrator assembly including a set of seals to isolate the electrical penetrator from the production bore. A secondary penetrator assembly provides a redundant pressure barrier for increased safety and system reliability.

A technique facilitates construction of a sealed electrical connector, e.g. sealed pothead assembly. Depending on the application, the electrical connector may be used to connect a power cable and a powered component such as an electric submersible pumping system. The electrical connector comprises at least one connector component and at least one electrical component. An injection molding process is used to construct an injection molded feature sealed to a corresponding component, e.g. to the at least one electrical component. The injection molded feature is readily formed and located between the at least one electrical component and the at least one connector component to form a simple and reliable seal which prevents unwanted passage of fluids

A connector includes a housing (10) with cavities (11) into which terminal fittings (T) connected to end parts of wires (W) are to be accommodated from behind. A wire holding assembly (30) is to be mounted to a rear part of the housing (10) and includes vibration limiting portions (31) configured to limit the vibration of the wires in the cavities (11) by entering the cavities (11) from behind. A wall (36) extends along an outer surface of the housing (10). Locks (23, 44) are provided on the outer surface of the housing (10) and in the wall (36) and lockable to each other in a front-back direction. An inclination preventing portion (47) projects forward from the wall (36) and extends along the outer surface of the housing (10).

An electrical connection component for a machine cable and suitable for transmission of power with voltage levels greater than or equal to 1 kV, comprises a first electrical contact arranged for electrically coupling with a second contact and arranged for direct or indirect coupling to a conductor of the machine cable, also comprises a housing in which at least a portion of the first electrical contact is positioned. The housing has a body portion that is formed from a first polymeric material that has a first hardness. The housing also has a layer covering at least a portion of an outer surface of the body portion, the layer being formed from a second polymeric material that has a second hardness that is lower than the first hardness. The electrical connection component is arranged such that the layer reduces a transmission of an external impact force to the body portion.

A pipeline inspection tool 300 of this disclosure is adapted for use a first pipeline service machine 200, including a control bar 210, when connected to a first valve 206 providing access to an interior of a pipe 52. The tool includes a connector 302 adapted for use in a pressurized pipeline, the connector including an electrical wire interconnect 308 and connectable at one end 304 to a distal end 212 of the control bar and connectable at another end 306 to a module 310, 310A, 310B of the pipeline inspection tool, module including a pressurized housing 314 containing the inspection tool. The module also includes a bulkhead 316 having a square O-ring 318 and a rod 320 that extends through the bulkhead to place the square O-ring in compression. In some embodiments, the tool includes two modules 310A, 310B, one containing a camera 330, the other containing lights 340.

A plug-in connector for contact with a stacking plate of an electrolyzer includes a sheet-metal part having a tulip contact for contacting the stacking plate and a cladding made of a material which is dimensionally stable at 1000 C. A single cladding is allocated to each sheet-metal part, respectively, for contacting a single stacking plate.
