ELECTRIC COMPRESSOR FOR VEHICLE-MOUNTED AIR CONDITIONER

摘要

A highly reliable inverter-integrated electric compressor for a vehicle-mounted air conditioner in which vibration and deformation of a circuit board and a bus bar due to vehicle vibration are suppressed to prevent dropping off of an element, breakage of a solder joint and a weld, and a circuit short circuit. The electric compressor (1) has an inverter receiving section (11) provided to the outer periphery of a housing (2), and an inverter device (20) is received in the inverter receiving section (11). A control circuit board (26) forming the inverter device (20) is screwed to fixing-screw seat surfaces (29) arranged at portions of the inverter receiving section (11). At least one or more bases (40) are arranged on the inverter receiving section (11), and the bases (40) have the same height as the fixing-screw seat surfaces (29) supporting positions near positions substantially in the middle portions between adjacent fixing screws of the control circuit board (26) and/or positions near those positions on the control circuit board (26) at which large components are placed.
