Two level curl, the one-level straight flange is parallel with the two level straight flange, and the distance of two straight flanges is 4mm, the one-level curl and two
Level curl is tangent with one-level straight flange and two level straight flange respectively, and whole magnetic core is on one-level straight flange and the midpoint line pair of two level straight flange
Claim, described plate upper surface includes three-level straight flange and level Four straight flange, and the one-level of the three-level straight flange and the center pillar top surface is straight
Side is located in approximately the same plane, and the plane is perpendicular to bottom plate.
Preferably, the face that the bottom plate contacts with lateral column is curved surface.
Preferably, the bottom plate, lateral column and center pillar are formed in one.
Preferably, the high 7.5mm of described lateral column, middle pillar height 5mm, the wide 6mm of bottom plate.
Preferably, the tangent line on the summit of described center pillar one-level curl is parallel with the tangent line on two level curl summit, and two cut
The distance of line is 7.7mm.
The beneficial effects of the utility model are：By being 4mm by the size increase of the one-level straight flange of center pillar and two level straight flange,
On the premise of EPC type magnetic core platypelloid type characteristics are met, increase power, reduce temperature rise.
