The invention discloses a rectangular case type electric power-assisted steering controller which comprises a PCB (Printed Circuit Board), a base and a cover board, wherein a conical support column and a heat conducting seat 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 base and the cover board are pressed together; installation bulges are inserted into corresponding installation notches; the conical support column is positioned in the cover board and enables the cover board and the base to be fastened tighter and tighter; four circular columns which are in rectangular distribution and extend upwards are integrally formed on the base; and the back side of the base is provided with four thread installation blind holes corresponding to the four circular columns in position. 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, and has a dustproof effect.
