Abstract

A motor-driven compressor includes a compression unit, an electric motor, a housing that includes an accommodating chamber and a wiring connection port, a motor driving circuit that includes a substrate arranged in the accommodating chamber, wiring electrically connected to the substrate and extending out of the housing through the wiring connection port, and a resin sealing member fitted to the wiring connection port. The wiring includes a primary conductor, which has a first end connected to the substrate and a second end, and a secondary conductor, which is connected to the second end of the primary conductor and arranged outside the housing. The secondary conductor includes a wire portion and a sheath that is made of an insulating material and covers the wire portion. The sealing member covers the sheath and a junction between the primary conductor and the secondary conductor.

Description

technical field [0001] The present invention relates to an electric compressor comprising a compression unit and an electric motor accommodated in a housing, and a base plate of a motor drive circuit accommodated in an accommodation chamber defined in the housing. Background technique [0002] Japanese Laid-Open Patent Publication No. 2011-144788 describes an example of an electric compressor installed in a vehicle. Such as Figure 7 As shown, an electric compressor 80 includes a housing 81 housing a compression unit and an electric motor 82 . The housing 81 includes one axial end connected to the inverter housing 84 . [0003] The housing 81 and the inverter housing 84 define a housing chamber housing the motor drive circuit 85 . The inverter housing 84 described above includes a tubular connector fitting 86 . The inverter case 84 further includes an insertion opening 87 for communicating the connector joint 86 with the accommodating chamber 83 . [0004] An internal co...
