Embodiment Construction

[0013] Combine below Figure 1 to Figure 4 Specific examples:

[0014] A soft magnetic metal magnetic powder core includes a bottom plate 4 on which a center post 3 and a side leg 1 are arranged. The side leg 1 and the center post 3 form a winding window 2 that can accommodate a coil.

[0015] Preferably, the center column is cylindrical, the center column is arranged at the opening of the bottom plate, and the distance between the outer arc of the center column and the opening is greater than or equal to the distance between the inner arc and the side leg.

[0016] Preferably, the side leg is horseshoe-shaped, and the outer side of the horseshoe-shaped side leg is a right-angle chamfer or an arc chamfer.

[0017] Winding window size requirements: such as figure 2 Among them, the width of 5 locations is greater than or equal to the width of 6 locations to ensure that the core bottom plate completely covers the coil to avoid magnetic leakage. The cross-sectional area of ​​21 points i...
