The invention discloses a simple electric control box specially used for controlling power-assisted steering, which comprises a PCB (Printed Circuit Board), a base and a cover board, wherein a conical support column and a heat conducting seat in a right trapezoid shape are integrally formed on the base; the PCB is arranged on the conical support column, is positioned through two positioning columns penetrating through the PCB, and is then fixed on the heat conducting seat by combining with screws; the cross sections of the two positioning columns are different; the conical support column is positioned in the cover board and enables the cover board and the base to be fastened tighter and tighter; the position, close to a left front corner, of the top of the cover board is provided with a circular anti-misloading mark; and four circular columns which are in rectangular distribution and extend upwards are integrally formed on the base, the back side of the base is provided with thread installation blind holes corresponding to the circular columns, and the back side of the base is provided with a plurality of strip-shaped heat conducting slots extending left and right. The structure effectively avoids the problem of unfirm connection between the base and the cover board as well as between the PCB and the base after installation and effectively avoids the problem of overhigh local temperature of the PCB, prevents the cover board and the PCB from being installed in an inverted way, and has a dustproof effect.
