Common mode inductor

The utility model discloses a common mode inductor, and relates to the technical field of common mode inductors. Comprising a framework and a magnetic core, the framework is provided with a transverse through hole, the magnetic core is inserted in the transverse through hole, a coil is wound on the magnetic core, the framework is provided with two end plates, clamping grooves are formed in the tops of the two end plates, grooves communicated with the clamping grooves are formed in the sides, away from each other, of the two end plates, and glands clamped in the clamping grooves are arranged on the two end plates. The two ends of the gland are provided with limiting arms clamped in the grooves, the sides, close to each other, of the two limiting arms are arranged in an inclined plane mode, the grooves are matched with the limiting arms in shape, and the two limiting arms are provided with clamping grooves which are tightened inwards to clamp the clamping grooves. According to the common mode inductor, through
