  • Installation structure of printed-circuit board for electronic control unit
    Patent number: 6341063
    Abstract: A casing of an ECU is formed within an air cleaner of an intake module for an internal combustion engine. The casing faces an intake air passage, and formed in a pocket, so that the casing is easily formed and the water and dust proof performances thereof are improved. A printed-circuit board to which a metal plate is fixed is inserted into the casing along slits formed on an inner wall of the casing. The slits pinch the printed-circuit board and the metal plate at the rear end area thereof. Thus, anti-stress and anti-vibration performances of the printed-circuit board are improved. The metal plate including convexes and concaved contacting portions is easily formed by pressing an aluminum or steel plate. Thus, the metal plate is formed with low cost. Further, the metal plate appropriately includes holes, thereby promoting the heat radiation and reducing the weight thereof.
