ABSTRACT:
A high pressure high temperature hermetically sealed electrical connector pin construction is set forth for use in down hole logging tools. On exposure to 28,000 psi at elevated temperatures, the present apparatus is able to handle such pressure and temperature cycling. Moreover, an elongate pin having two ends for forming electrical connections is used, the pin having a shoulder, a central threaded portion on one side of the shoulder and is formed of conductive metal that joins with a plastic body which is bonded thereto either by in situ molding to the pin or by an epoxy resin and the pin further threads to the body. In a multipin construction, the body is a circular insert for a surrounding cylindrical steel housing.
