Electric compressor

Abstract

In an electric compressor, an inverter includes a circuit board on which an electronic component is mounted, and an inverter housing portion that houses the inverter includes a housing body, a board fixing portion to which the circuit board is to be fixed, and a cover member. A predetermined electronic component included in the electronic component, such as a smoothing capacitor and a filter capacitor, is fixed to and disposed on the cover member-side surface of the circuit board in a state of being molded and sealed with thermosetting second insulating resin, and a vibration insulating member that reduces vibration of the cover member is disposed between the molded and sealed predetermined electronic component and the cover member.

         3 . The electric compressor according to  claim 2 , wherein
 the case member is fastened and fixed to the board fixing portion together with the circuit board.   
     
     
         4 . The electric compressor according to  claim 2 , wherein
 the cover member has a bulging portion that bulges in a direction away from the circuit board than other portions of the cover member and houses a tip end side of the case member therein, and   the vibration insulating member is sandwiched between a tip end surface of the case member and an inner surface of the bulging portion of the cover member.   
     
     
         5 . The electric compressor according to  claim 1 , wherein
 the predetermined electronic component is integrated with the circuit board by the thermosetting resin, and   the vibration insulating member is sandwiched between the molded and sealed predetermined electronic component and the cover member.   
     
     
         6 . The electric compressor according to  claim 5 , wherein
 the cover member has a bulging portion that bulges in a direction away from the circuit board than other portions of the cover member and houses a tip end side of the molded and sealed predetermined electronic component therein, and   the vibration insulating member is sandwiched between a tip end portion of the molded and sealed predetermined electronic component and an inner surface of the bulging portion of the cover member.   
     
     
         7 . An electric compressor comprising:
 a housing that houses an electric motor and a compression mechanism driven by the electric motor;   an inverter that drives the electric motor, the inverter including a circuit board on which an electronic component is mounted;   an inverter housing portion that houses the inverter, the inverter housing portion including a housing body having an opening, a board fixing portion which is provided so as to protrude from an inner bottom surface of the housing body facing the opening and to which the circuit board is fixed, and a cover member that closes the opening of the housing body; and   a vibration insulating member that reduces vibration of the cover member,   wherein a predetermined electronic component included in the electronic component is disposed on a cover member-side surface of the circuit board, and   the vibration insulating member is sandwiched between the predetermined electronic component and the cover member.   
     
     
         8 . The electric compressor according to  claim 7 , wherein
 the cover member has a bulging portion that bulges in a direction away from the circuit board than other portions of the cover member and houses a tip end side of the predetermined electronic component therein, and   the vibration insulating member is sandwiched between a tip end portion of the predetermined electronic component and an inner surface of the bulging portion of the cover member.   
     
     
         9 . The electric compressor according to  claim 1 , wherein
 the predetermined electronic component includes at least one of a smoothing capacitor that smooths DC voltage from a DC power supply, a filter capacitor that forms a noise filter, or a filter coil that forms the noise filter.   
     
     
         10 . The electric compressor according to  claim 7 , wherein
 the predetermined electronic component includes at least one of a smoothing capacitor that smooths DC voltage from a DC power supply, a filter capacitor that forms a noise filter, or a filter coil that forms the noise filter.
