Inverter-integrated electric compressor
First Claim
1. An inverter-integrated electric compressor in which an inverter accommodating section is provided on a periphery of a housing accommodating an electric motor and a compressing mechanism, and an inverter device that converts DC power supplied from a high-voltage power supply into three-phase AC power and supplies the three-phase AC power to the electric motor in the housing via a glass-insulated terminal is accommodated inside thereof,wherein the inverter device includes an inverter module constructed by integrally modularizing a power circuit board on which a semiconductor switching device and so on are mounted and a control board on which control and communication circuits and so on operating at low voltage are mounted,wherein attachment legs protruding outward from a module main body are provided at both ends of at least one side surface of the inverter module, andwherein the inverter module is accommodated in the inverter accommodating section by positioning the attachment legs in spaces at both ends of the glass-insulated terminal.

Abstract
Provided is an inverter-integrated electric compressor capable of reducing the size of an inverter accommodating section by modularizing a power circuit board and a control board and further reducing the size of an inverter device, as well as an accommodating section thereof, by improving the positional structure with respect to other electrical components. An inverter-integrated electric compressor including an inverter accommodating section provided on a periphery of a housing accommodating an inverter device includes an inverter module constructed by integrally modularizing a power circuit board and a control board, wherein attachment legs provided on both edges of at least one side surface of the inverter module protrude outward from a module main body, and the inverter module accommodates the inverter accommodating section with the attachment legs positioned in spaces at both ends of a glass-insulated terminal.
