  • Sealed terminal assembly for hermetic compressor
    Patent number: 6372993
    Abstract: A terminal assembly for a hermetic compressor having a shell includes a terminal block secured to the shell. A terminal fence surrounds the terminal block and is also fixedly secured to the shell. An intermediate gasket sealingly engages both the shell and the terminal block. A power plug is electrically connected to the terminal block and sealingly engaged by the intermediate gasket. A terminal block cover is secured to the shell in order to retain the connection between the various components. The terminal assembly once properly installed is capable of sealing the electrical connection for the compressor from direct contamination by high humidity and salt water spray normally experienced during trans-oceanic shipping.
