<p>The regulator casing comprises at least one circuit board from which a plurality of insulated electrical wires (3, 3'; 4, 4') extend,<BR> ```a dish-shaped metal container (10) in which the circuit board is fitted and which has at least one slot or opening (21) through which the electrical wires can extend, and a seat adjacent the slot or opening (21),<BR> ```a grommet (25) of electrically insulating material, through which the wires extend and which can be fitted in the seat in the container (10), the grommet (25) having an internal duct which, after the grommet has been positioned in the seat, permits the injection of a setting sealant material for sealing the spaces between the wires (3, 3', 4, 4') and the grommet (25) in a leaktight manner, and<BR> ```a cover (40) fined on the container (10) over the circuit board. The spaces between the cover (40), the container (10), and the grommet (25) are sealed in a leaktight manner by means of a setting sealant. The circuit board is an electronic speed regulator for an electric motor, particularly for a fan associated with a car radiator.</p> |
