Abstract
A sealed compressor has an electric motor received within a hermetically sealed shell. The electric motor drives a compressor pump unit. An electric connection provides electric power to the motor. A terminal housing is mounted on the shell, with a terminal plug for supplying electrical power from outside of the shell into a connector within the shell. A grommet is at an opening in the shell which allows passage of the electric connector from the terminal plug to the electric connection. The grommet has a first surface positioned on an opposed side of a wall of a housing spaced from the shell, and a second surface sealing against the shell. The grommet has an interior portion allowing passage of the electrical connections from the terminal plug into the electric connector within the shell.
