Abstract

An object of the present invention is to provide an electric compressor capable of easily connecting a conductive member to the connection terminal while maintaining insulation between the connection terminal and the housing. The electric compressor includes: a compression unit, an electric motor, a motor drive circuit, a conductive member electrically connected to the motor drive circuit, motor wiring, a connection terminal for electrically connecting the motor wiring to the conductive member, and an insulation housing the connection terminal inside. The terminal receiving member, and the housing. The terminal accommodating member includes a terminal holding member for holding the connection terminals, and a block for accommodating the terminal holding member. The terminal holding member has a holding portion that holds the connection terminal, and a closing wall portion that passes through the motor wire and closes the opening of the receiving hole.

Description

technical field [0001] The present invention relates to electric compressors. Background technique [0002] The electric compressor disclosed in Japanese Patent Application Laid-Open No. 2013-245555 includes: a compression unit for compressing refrigerant; an electric motor for driving the compression unit; a motor drive circuit for driving the electric motor; a conductive member electrically connected to the motor drive circuit; Motor wiring from the motor. In addition, the electric compressor includes: a connection terminal electrically connecting the motor wiring and the conductive member; an insulating terminal housing member housing the connection terminal; and a case housing the compression unit, the electric motor, and the terminal housing member. The terminal accommodating member has a block accommodating the connection terminals and a cover member covering the entire block. The block has an opening for accommodating the connection terminal therein. The opening of...
