INVERTER CIRCUIT BOARD AND INVERTER-CONTAINING ELECTRIC COMPRESSOR USING SAME

摘要

Provided is an inverter circuit board to which a P-N terminal is attached firmly and attached such that stress applied to the circuit board can be distributed, making it possible to prevent detachment of the P-N terminal or damage to the circuit board or any components mounted thereon. Also provided is an inverter-containing electric compressor. A P-N terminal (29) via which DC power is inputted is attached to this inverter circuit board (23), on which an inverter circuit (22) is mounted. The P-N terminal (29) is provided with the following: a pair of pins; a busbar of a prescribed length joined perpendicularly to one end of each pin; a resin molded member formed integrally with the pair of pins and the busbars; and surface-mounting terminals, soldered to the surface of the circuit board, and through-hole terminals, inserted into and soldered to through-holes (23A) in the circuit board, said terminals being provided on the pair of busbars. The surface-mounting terminals and through-hole terminals are attached to the circuit board by being soldered thereto.
