Title:
INVERTER-INTEGRATED ELECTRIC COMPRESSOR AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/051718
Kind Code:
A1
Abstract:
Provided is an inverter-integrated electric compressor that achieves a large cost reduction due to a reduction in the number of components and the amount of assembly man-hours and due to a decrease in loss-related expenses. A circuit board 17 of an inverter circuit part 3 has: fastening holes 33 formed through the circuit board; and a connecting hole which has, on an inner surface thereof, a conduction part for conducting to wiring and is formed to penetrate through the circuit board. An electric power switching element 13 has a press-fit terminal 14. Caulking shafts 61 are formed in a protruding manner in a motor housing 4. The caulking shafts are inserted through the fastening holes and the caulking shafts that protrude from the fastening holes are deformed, whereby the circuit board is caulked and fastened to the motor housing. The press-fit terminal is press-fitted into the connection hole, whereby the electric power switching element is electrically connected to the circuit board.
