Abstract

An electronic control unit includes a base plate that has a load-bearing area and a mounting area provided on a side of the load-bearing area. At least one guide hole penetrates the base plate and is provided in the mounting area. The electronic control unit further includes a housing mounted on the load-bearing area of the base plate. The housing includes a top wall and side walls extending downward from an edge of the top wall and continuously disposed around the top wall, with the top wall and the side walls collectively defining the accommodating space of the housing. The electronic control unit further includes a printed circuit board housed in the accommodating space between the base plate and the housing. Also, the electronic control unit includes an electrical connector electrically connected to the printed circuit board. The electrical connector is exposed through an opening provided on one of the side walls and is positioned above the guide holes. The electronic control unit has enhanced waterproof capabilities that are capable of effectively preventing water from entering the interior of the electronic control unit thereby improving the service life and operating precision of the electronic control unit.
