WIPO Patent Application WO/2022/118880
Kind Code:
A1
Abstract:
According to the present invention, a circuit board (3) is accommodated in a housing (2), and an electrolytic capacitor (11) is mounted on a first surface (3A) of the circuit board (3). As a gas path (31), a first path (32) is formed, in the thickness direction of the circuit board (3), corresponding to an explosion-proof mechanism of the bottom surface of the electrolytic capacitor (11), and a second path (33) is formed which passes through the inside of the circuit board (3) along surfaces (3A, 3B) of the circuit board (3). When the explosion-proof mechanism is open and a gas is discharged, the gas is guided to a wide space (36) from a space (35) inside the housing (2) through a recessed groove (34) of the first surface (3A).
