[0005] To achieve the above object, the utility model provides the following technical scheme: including the winding frame that can be wound inductance coil and the baffle of being set in the both ends of winding frame, at least one pair of symmetric insulation plate that is shielded in the outside of coil for electromagnetic shielding is provided between the baffle.

[0006] Preferably, the cross section of the winding frame is rectangular.

[0007] Preferably, the baffle extends radially outward along the internal passage of the winding frame, and the cross section of the baffle is in the shape of a mouth.

[0008] Preferably, the winding frame includes a group of straight plates and side plates, and the straight plates are oppositely arranged on both sides of the notches of the side plates.

[0009] Preferably, the cross section of the straight plates is trapezoidal, and the cross section of the side plates is in the shape of an I-beam.

[0010] Preferably, the insulation plates are oppositely arranged on the outer sides of the straight plates.

[0011] Preferably, the bottom of the baffle is provided with a sliding groove, and the upper and lower ends of the insulation plates slide in the sliding groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By inserting the insulation plates into the sliding groove provided at the bottom of the baffle, the sliding groove insulates the coil wound outside the winding frame, and blocks the electromagnetic interference. Attached Figure Description
