<p>In an automotive vehicle, electrical components are housed in a waterproof connection box (1). An electronic control circuit (6) susceptible to heat damage is accommodated in a first accommodation portion (4) of the body of the electrical connection box (1), while a relay box (7) and a fusible link box (8) which release heat in use are accommodated in a second accommodation portion (5) of the body. The cover (3) is similarly sub-divided. Air is exhausted from the space (5) into the engine room through an exhaust pipe (10), and cool air from outside the vehicle flows into the space (5) through an intake pipe (9). Wire harnesses (13,14) connected with the components (6,7,8) are inserted through waterproof grommets. Heating of the electronic control unit (6) by the engine and by the heat releasing components (7,8) is minimized, and good waterproofing is achieved. <IMAGE></p> |
