<p><P>PROBLEM TO BE SOLVED: To provide an electric connection box with improved heat dissipation properties. <P>SOLUTION: A power substrate 18 and a control substrate 20 are housed in a casing 11. The casing 11 includes a base part 15, and a power substrate housing part 19 and a control substrate housing part 21 which protrude from an upper wall 16 of the base 15, face each other with a gap, and house both substrates 18, 20. A ventilation passage 43 for circulating air is formed between the housing parts 19, 21. At a connector block 14, a fitting part 34 is formed which opens in the direction different from the protruding direction of both housing parts 19, 21 and can be fitted to a mating connector. In the fitting part 34, a first terminal metal fitting 35 and a second terminal metal fitting 37 are arranged which can be electrically connected to the mating connector. The terminal metal fittings 35, 37 are introduced into the casing 11, and electrically connected to the control substrate 20 and an auxiliary circuit substrate 22. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
