The bottom of the magnetic core body 10 is inserted into the transverse groove 31, and the front and rear side walls of the bottom of the magnetic core body 10 are close to the front and rear inner walls of the transverse groove 31.

[0019] Furthermore, the small frame 40 is wound with windings 41, and the four connection ends 42 of the two windings 41 extend upward above the middle through slot of the upper insulating clamping plate 60 and the corresponding long through slot 21 on the top glass fiber insulating plate 20. In the attached figure, there is a short-circuit plate connected between the two connection ends 42, which needs to be removed during subsequent installation.
[0020] Furthermore, the corresponding edges of the glass fiber insulation board 20, the bottom plate 30, and the two insulation clamping plates 60 are sleeved with a plurality of vertical fixing screws 1, and each vertical fixing screw 1 is screwed with a first nut 2, a second nut 3, a third nut 4, and a fourth nut 5 in sequence from top to bottom, the bottom rotating portion of the vertical fixing screw 1 is below the bottom plate 30, the fourth nut 5 is clamped between the bottom rotating portion of the vertical fixing screw 1 and the bottom surface of the bottom plate 30, the top surface of the third nut 4 is pressed against the bottom surface of the insulation clamping plate 60 below, the bottom surface of the second nut 3 is pressed against the top surface of the insulation clamping plate 60 above, and the bottom surface of the first nut 2 is pressed against the top surface of the glass fiber insulation board 20. The vertical fixing screw 1, the first nut 2, the second nut 3, the third nut 4, and the fourth nut 5 are all made of nylon material and have an insulation effect.
