Conductor feedthrough and method of manufacture therefor

Abstract

A conductor feedthrough is provided for allowing an electrical conductor, cable, wire, etc., to be passed through a wall of a pressurized vessel (e.g., a compressor vessel forming part of a refrigeration or air conditioning system) while maintaining a hermetic seal within the vessel and providing resistance to mechanical stress imparted on the conductor. The feedthrough comprises a first casting formed on a portion of a conductor, a fitting engageable with the first casting and inserted into an aperture in a vessel wall, and a second casting formed on an end of the first casting. The fitting is engaged with the first casting in such a manner as to prevent relative rotational movement between the first casting and the fitting. The feedthrough maintains a hermetic seal within the vessel and locks the conductor in place to provide resistance to mechanical stress and/or torque applied to the conductor.
