Abstract
Electrical equipment coupled to a printed circuit board provides insulation ribs projecting from a face between terminal plates provided on an upper face of the electrical equipment. The insulation ribs are inserted into oblong holes of the printed circuit board when the electrical equipment is coupled to the printed circuit board. As a result, insulation distances, namely creepage distance, between the terminal plates are along the height of the insulation ribs projecting from the upper face of the terminal plates.
