  • Publication number: 20100254833
    Abstract: Provided is a terminal device for an electric compressor including: a partition wall arranged between a container part for a compression mechanism drive motor present with a lubricant-containing fluid to be compressed and a circuit part for supplying power to the motor; and a power supply terminal member hermetically extending through the partition wall so as to supply power to the motor. An electric communication portion of the terminal member extending between the two parts is covered with insulating varnish.
