Iron core reactor and magnetic circuit clamping device thereof

The utility model discloses an iron core reactor and a magnetic circuit clamping device of the iron core reactor. The magnetic circuit clamping device comprises two pulling plates which are arranged oppositely and a plurality of magnetic circuit spacing plates. The plurality of magnetic circuit interval plates are fixed between the two pulling plates. Protrusions are arranged at two ends of each of the magnetic circuit spacing plates. The concave holes matched with the protrusions are formed in the pulling plates. An iron core is clamped between the two pulling plates. According to the magnetic circuit clamping device, on one hand, the iron core on the middle separating section of the magnetic circuit can be guaranteed to be effectively spaced by magnetic circuit spacing plates and not penetrate out of the magnetic circuit spacing plates; on the other hand, clamp degree of the iron core is strengthened, and the impregnation quality of the iron core reactor is enabled to be better, so that the integral strengt
