FEEDTHROUGH ASSEMBLY FOR WELL-LOGGING TOOL

摘要

A well-logging tool for a geological formation has a housing to be positioned within a borehole and has first and second openings. A feedthrough assembly includes an elongate electrical conductor having opposing first and second ends and a medial portion extending therebetween. An integrally formed, monolithic, dielectric layer surrounds the elongate electrical conductor and includes a first enlarged diameter end portion surrounding the first end of the elongate electrical conductor and is positioned within the first opening. A second enlarged diameter end portion surrounds the second end of the elongate electrical conductor and is positioned within the second opening. A reduced diameter portion surrounds the medial portion of the elongate electrical conductor.
