Abstract: Assembly workability of an electric compressor to which an inverter circuit section and a filter circuit section are attached is improved. The inverter circuit section (3) includes an inverter control board (17), a sleeve assembly (18), and a power module (14). The inverter control board, the sleeve assembly, and the power module are integrated. The filter circuit section (4) includes a filter circuit board (66) and a support member (67). The filter circuit board (66) and the support member (67) are integrated. The inverter circuit section and the filter circuit section are structured to be capable of being stored each individually within an inverter storing section (8) from the same direction and detachably attached to the housing (2).

Abstract: An electric compressor is provided which is capable of reducing the number of components in an inverter circuit section installed in an inverter storing section and attaining its miniaturization as well. A sleeve assembly (18) of an inverter circuit section (3) has positioning pins (37) and (38) for an inverter control board (17) and a power module (14). The positioning pins (37) and (38) are thermally caulked in a state in which the sleeve assembly (18) is interposed by the inverter control board (17) and the power module (14) to thereby make the inverter circuit section (3) integral. The integrated inverter circuit section (3) is installed in an inverter storing section (8) constituted on an outer surface of a housing (2).

Abstract: An electric compressor is provided in which the connection strength between lead terminals from a motor and an inverter circuit section is improved. The electric compressor 1 is constituted by electrically connecting lead terminals 24 to 26 of a motor and an inverter circuit section 3 for supplying power to the motor by a motor side connection terminal 28. The inverter circuit section 3 is protrusively provided with terminal connection portions 19 to 21 each having a screw groove portion. The motor side connection terminal 28 has a flat plate terminal portion. The flat plate terminal portion is fixed to the inverter circuit section 3 by a nut 91 screwed into each of the screw groove portions of the terminal connection portions 19 to 21 and electrically connected to the inverter circuit section 3 in that state.

Abstract: There is provided an electric compressor in which the connection strength between an inverter circuit section and an electrical circuit section connected thereto by a connection terminal is improved. An inverter circuit section (3) includes an inverter control board (17) and a resin-molded sleeve assembly (18). In the sleeve assembly, a sleeve (32) and a terminal connection portion (23) are integrally resin-molded in a state in which a screw groove portion is protruded. The inverter control board (17) and a filter side connection terminal (71) of a filter circuit section (4) are fastened together to the terminal connection portion with a nut (92) screwed into the screw groove portion, whereby the inverter control board 17 and the filter circuit section 4 are electrically connected.
