Abstract

The present invention provides an electric compressor capable of downsizing. The electric compressor is equipped with: an electric motor (131), which drives the compression mechanism (161); a drive circuit (121), which drives the electric motor (131); and a housing (111), which divides the electric motor (131) a motor chamber (151) for housing; a cover member (126), which cooperates with the case (111) to define a driving circuit chamber (152) for housing the driving circuit (121); and a relay terminal part (521) electrically connects the wires connected to the drive circuit (121) and the wires connected to the electric motor (131). The casing (111) has a partition wall (113) that partitions the motor chamber (151) and the drive circuit chamber (152). The relay terminal portion (521) is arranged between the partition wall (113) and the rotation shaft (156).

Description

technical field [0001] The present invention relates to a general electric compressor, and more particularly to an inverter-integrated electric compressor. Background technique [0002] Regarding the conventional electric compressor, for example, Japanese Patent Application Laid-Open No. 2012-184752 discloses the following electric compressor. short circuit (Patent Document 1). [0003] The electric compressor disclosed in Patent Document 1 includes: a casing; a compression mechanism and an electric motor housed in the casing; and an inverter casing fixed to a part of the outer peripheral wall of the casing to form an inverter housing chamber. ; and the inverter and airtight terminals, which are arranged in the inverter housing room. The airtight terminals are electrically connected to the inverter via a connector on the inverter side, and are electrically connected to lead wires drawn from the coils of the stator via a cluster block inside the case. [0004] In addition,...
