Abstract

Provided is an inverter-integrated electric compressor excellent in joining strength and joining reliability at electrical joint. An inverter-integrated electric compressor wherein a motor is incorporated and a motor drive circuit including the inverter is surrounded by a compressor housing, characterized in that a bus bar joint section at which bus bars are electrically joined together is provided in the motor drive circuit, and a tip of at least one of the bus bars, the tip being located at the bus bar joint section, is split into small joining sections.

Claims

exact text as granted — not AI-modified
1 . An inverter-integrated electric compressor, wherein a motor is incorporated and a motor drive circuit including an inverter is provided in a housing space surrounded by a compressor housing, wherein a bus bar joint section at which bus bars are joined together to connect electrically is provided in said motor drive circuit, and that a tip, which is located at said bus bar joint section, of at least one of said bus bars is split into small joining sections. 
     
     
         2 . The inverter-integrated electric compressor according to  claim 1 , wherein said tips of both bus bars are provided with small joining sections. 
     
     
         3 . The inverter-integrated electric compressor according to  claim 1 , wherein at least one of said bus bars is provided as standing up from a board of said motor drive circuit. 
     
     
         4 . The inverter-integrated electric compressor according to  claim 1 , wherein at least one of said bus bars is provided on an IPM. 
     
     
         5 . The inverter-integrated electric compressor according to  claim 1 , wherein said joining is performed by a TIG welding. 
     
     
         6 . The inverter-integrated electric compressor according to  claim 1 , wherein the compressor is a compressor used for automotive air conditioning systems. 
     
     
         7 . The inverter-integrated electric compressor according to  claim 6 , wherein said compressor is mounted to an automotive engine.
