Abstract: An electric compressor includes a compression portion, an electric motor, a drive circuit, a housing having a cylindrical shape and accommodating the compression portion and the electric motor, a cover attached to the housing and cooperating with the housing to accommodate the drive circuit, and a protector. The protector is configured to protect the cover from an external force. The protector includes a fixing portion that is fixed to the housing and a protection portion that is formed in a plate-like shape. The protection portion is disposed to face and to be spaced from the cover. The protector extends in a diametrical direction of the housing. A plurality of recesses is formed in the protection portion toward the cover such that the protection portion projects toward the cover. The recesses extend in an extending direction of the protector.

Abstract: An electric compressor includes a housing and a cover. The housing accommodates a compression portion and an electric motor. The cover is attached to an outer surface of the housing and cooperates with the outer surface of the housing to define an accommodation space. An inverter is accommodated in the accommodation space and configured to drive the electric motor. The inverter includes a circuit board, an electrolytic capacitor, and a capacitor cover at least partly covering the electrolytic capacitor. The electrolytic capacitor includes a cylindrical main body having a first end and a second end, a lead extending from the first end of the main body and connected to the circuit board, and a pressure relief vent on the second end of the main body. The capacitor cover is interposed between the circuit board and a peripheral edge of the second end of the electrolytic capacitor.

Abstract: The electric compressor includes a housing having electrical conductivity, an inverter, a cover having electrical conductivity, a sealing portion, and a shielding portion having electrical conductivity. The cover is attached to the housing, thereby defining an accommodating space in which the inverter is accommodated. The sealing portion has a main body portion made of resin and a metal portion having electrical conductivity. The sealing portion is provided in a gap between the housing and the cover. The shielding portion is joined to the metal portion and electrically grounded. The metal portion is provided in the accommodating space, and has an outer circumferential edge embedded in the main body portion. The shielding portion is arranged so as to face a third surface of the main body portion and so as to extend from the metal portion toward at least one of the first surface and the second surface.
