HIGH-PRESSURE HERMETIC TERMINAL

摘要

A hermetic power terminal feed-through for use in high-pressure applications is disclosed as including a fused pin subassembly comprising a tubular reinforcing member and a current-conducting pin. The pin passes through the tubular reinforcing member and is fixed thereto by a fusible sealing material to create a hermetic seal. The fused pin subassembly is then joined and hermetically sealed to a terminal body. A method for manufacturing the high-pressure hermetic power terminal feed-through is also disclosed.

主权项

1. A high-pressure hermetic terminal comprising:
a cap-shaped, metal body comprising a generally planar top wall and a cylindrical side wall, the top wall comprising a thickness and having an opening extending therethrough in the direction of a longitudinal axis, the opening comprising a sidewall having a length equal to the thickness of the top wall; a metal, tubular reinforcing member located within the opening and extending along the longitudinal axis, an outer diameter of the reinforcing member being sized to closely fit within the opening such that an exterior surface of the reinforcing member is adjacent to a wall of the opening, the reinforcing member being joined to the body by a filler metal; a current-conducting pin extending through the reinforcing member along the longitudinal axis; and an electrically insulating fusible sealing material joining and hermetically sealing the current-conducting pin to the reinforcing member.
