The present disclosure relates to a motor operated compressor, including a housing, a compressor provided in the housing, a motor connected to the compressor to drive the compressor, an inverter coupled to one side of the housing, and connected to the motor unit in an electrically conductive manner. The motor operated compressor includes a hermetic terminal assembly, one side of which extends into the inverter unit, and an opposite side of which extends into the housing. A plurality of busbars have one end of each busbar connected to the opposite side of the hermetic terminal assembly, and the other end of each busbar connected to the motor unit. A first insulating cover portion encloses and seals the hermetic terminal assembly and the plurality of busbars inside the housing, such that a conductive body connecting the motor unit and the inverter unit in the main housing is sealed from refrigerant.
