HERMETIC TERMINAL WITH ELECTRICALLY INSULATING ANTI-TRACKING CAP

摘要

A hermetic terminal for carrying electric current into the housing of a hermetic compressor, including a cup-shaped metallic body member having a plurality of metallic conductor pins extending therethrough which are electrically insulated from the body member by hermetic glass seals. The body member includes a closed end having an inwardly facing contoured end surface, to which a correspondingly contoured contacting surface of an electrically insulating cap member is secured by means of a uniform layer of electrically insulating bonding material therebetween. The pins extend through passages in the cap member, whereby the cap member defines an oversurface distance between the pins and the body member. A portion of the oversurface distance is protected from contaminants within the compressor housing by means of an annular gap between the outer periphery of the cap member and the sidewall of the body member, and by respective annular gaps between the pins and corresponding passages in the cap member.
