The invention discloses an electric control box used for controlling power-assisted steering. The electric control box comprises a PCB, a base and a cover plate. Tapered support columns and a right-angle trapezoidal thermal conduction seat are integrally formed on the base, the PCB is arranged on the tapered support columns, positioned through penetrating two positioning columns of the PCB and fixed to the thermal conduction seat by combining a bolt, the base and the cover plate are pressed together, installation bulges are inserted into corresponding installation notches, the tapered support columns are positioned in the cover plate, to cause the cover plate and the base to be buckled tighter and tighter, a round malassembly prevention mark is arranged on the position, close to the left front corner, of the top of the cover plate, four rectangularly-distributed upwards-extending cylinders are integrally formed on the base, threaded installation blind holes having equal number and corresponding position with the cylinders are formed in the back of the base, and a plurality of right-left extending bar-type thermal conduction grooves are formed in the back of the base. By adopting the structure, the problems that the base and the cover plate, and the PCB and the base shake slightly after being installed, the temperature of part of the PCB is too high, and the cover plate is arranged reversely are effectively avoided, and the electric control box used for controlling power-assisted steering has as a dustproof effect.
