ELECTRIC COMPRESSOR FOR AUTOMOBILE USE

摘要

An electric compressor for automobile use can satisfy a plurality of requirements, including protection of an inverter substrate, suppression of electromagnetic noise, vibration and noise, and the like. A cover (20B) covering the opening of the housing (11) of an electric compressor is made by laminating a conductive material layer (21) and an insulating material layer (22) composed of an insulating material. The conductive material layer (21) of the cover (20B) prevents leakage of electromagnetic noise radiated from an inverter substrate (12), and the like, to the outside of the housing (11). On the other hand, the insulating material layer (22) is provided to face inward of the housing (11) so that the inverter substrate (12) to which a high voltage is applied and the conductive material layer (21) of the cover (20B) are insulated from each other, thus making the electric compressor compact. Furthermore, vibration of the conductive material layer (21) is suppressed by the insulating material layer (22), thus reducing vibration and noise of the electric compressor.
