摘要： A hermetic compressor according to the present disclosure may include an oil guide disposed on a rotating shaft between a driving motor and a main frame, the oil guide may include an oil block surrounding a main bearing surface between the main frame and the rotating shaft, and one end of the oil block may radially overlap a shaft support protrusion of the main frame. This can suppress oil returned after lubricating a compression unit from being scattered, thereby reducing a leakage of the oil to outside of a casing through a refrigerant discharge pipe.

摘要： Disclosed is an electric compressor. An electric compressor according to an embodiment of the present disclosure includes an electrically conductive part for electrically conductively connecting an inverter and a motor part. The motor part is detachably inserted through and coupled to the inverter and the motor part. Accordingly, the inverter and the electrically conductive part may be electrically conductive to each other by a simple structure. The electrically conducive part includes an elastic member. The elastic member is configured to cancel vibration generated along with the operation of the motor part. When the motor part is vibrated and moved, the elastic member is compressed or stretched to prevent the vibration of the motor part from being transferred to the inverter. Thus, it is possible to prevent the inverter from being damaged due to the vibration of the motor part. The electrically conductive part is brought into direct contact with a printed circuit board in the inverter. Accordingly, a busbar assembly for electrically conductively connecting the printed circuit board and the electrically conductive part is not required. As a result, there is no need for a space for housing the busbar assembly in the inverter, and thus it is possible to miniaturize the inverter and further the electric compressor.
