Refrigerator Compressors Electrical Connecting Terminals

Two types of terminal connections are used with hermetic and semi-hermetic compressors. On the hermetic compressors, pins or terminals are sealed within bakelite or ceramic. The semi-hermetic compressors use terminal boards with threaded bolts being used for the terminals. The board has an ‘0’ ring on both sides of it. The ‘0’ ring is designed to compress against the board and prevent the leakage of refrigerant and oil around the terminals.
