  • Patent number: 6631071
    Abstract: A reliable capacitor module is provided which can solve the following problem: when a plurality of capacitors is mounted on a wiring board, the wiring board is distorted and deformed by the weight and cracks appear on mounting holes and the main body of the wiring board. The bottoms of metallic cases of the capacitors are fit in recesses formed on a mounting plate. In this state, lead wires drawn from the upper surfaces of the capacitors are electrically connected via the wiring board. With this configuration, a weight load of the plurality of capacitors is not applied at all, thereby preventing distortion and deformation of the wiring board and vibration causing cracks on the main body of the wiring board.
