PRESSURE-BLOCKING FEEDTHRU WITH PRESSURE-BALANCED CABLE TERMINATIONS

摘要

A pressure-blocking feedthru that is exposable to varying temperatures and pressures includes various components. For example, the pressure-blocking feedthru might include pressure-blocking assemblies that each include a respective pressure-barrier shell and insulated pin assembly. The pressure-blocking feedthru also includes an interface assembly that couples the pressure-blocking assemblies to one another. The interface assembly includes a double-ended socket for coupling the insulated pin assemblies and a sleeve that circumscribes the doubled ended socket and at least part of the first and the second ceramic pin assemblies. In addition, the pressure-blocking assemblies might each be connected to a cable-connection assembly that employs a pressure-balanced cable termination.
