The thickness d of the capacitor insertion hole 4 of the terminal plate 2 is thinner, and the 2M8 capacitor lead wiring is provided on the bottom of the terminal plate 2, which weakens the strength of the terminal plate 2. Problems such as deformation of the terminal plate 2, destruction of the internal capacitor 10, and narrowing of the spacing between the pin terminals 9 have occurred. In addition, burrs were likely to occur in the fitting window 6 of the terminal plate 2 of the mold, resulting in insufficient fitting and shortened mold life.
