Electric compressor

Abstract

An electric compressor includes a rotary shaft, a compression part, a motor, an inverter, an inverter housing, a motor housing arranged next to the inverter housing in a radial direction of the rotary shaft, a compression part housing, a shaft support member, a conductive pin that is electrically connected to the motor, an inverter terminal, and an electrical connecting member. The electrical connecting member has a busbar, a first terminal, a second terminal, and a case. The busbar is bent such that the first terminal is engaged with the conductive pin and the second terminal is engaged with the inverter terminal by moving the electrical connecting member in an axial direction of the rotary shaft.

What is claimed is: 
     
         1 . An electric compressor comprising:

         2 . The electric compressor according to  claim 1 , wherein
 the first terminal is a receptacle terminal with which the conductive pin is engaged in the axial direction,   the second terminal extends in the axial direction, and   the busbar has an edge-wise bending portion at which the busbar is bent by edge-wise bending so that the second terminal is engaged with the inverter terminal and a pair of flat-wise bending portions at which the busbar is bent between the edge-wise bending portion and the receptacle terminal by flat-wise bending so that a position of the receptacle terminal is adjusted in a surface direction of the bottom wall of the motor housing, the surface direction being perpendicular to the axial direction.   
     
     
         3 . The electric compressor according to  claim 2 , wherein
 the receptacle terminal has an opening into which the conductive pin is inserted; and   an opening diameter of the opening is larger than a diameter of the conductive pin.   
     
     
         4 . The electric compressor according to  claim 1 , wherein
 a high voltage connector that supplies power from an external power source to the motor and a communication connector that sends control signals from an external controller to the inverter are each connected to the inverter housing, the control signals having a power smaller than the power supplied from the external power source, and   the high voltage connector is disposed on an opposite side to the communication connector across the electrical connecting member.   
     
     
         5 . The electric compressor according to  claim 1 , wherein
 the inverter housing has an extending portion that extends from the bottom wall of the motor housing in the axial direction, and   the extending portion protrudes from the bottom wall of the motor housing in the axial direction over the electrical connecting member.
