Double magnetic circuit ironcore

The utility model discloses a magnetic conductive core used in magnet conductor provided with two groups of transformer coil. The utility model comprises a first core and a second core. The first core is provided a left central core on the left side and a right central core on the right side. And outside the left central core is provided a left external hoop core, while outside the right central core is provided a right external hoop core. Between the left central core and the right central core is arranged a leakage sensing core and the second core has she same structure with the first core and is connected with the first core symmetrically. What needs to be noted is that the empty space between the leakage sensing core of the first core and the leakage sensing core of the second core forms a high leakage inductance producing area, across which the utility double magnetic circuit core provides the two groups of transformer coil with multiple high voltage output and high leakage sensing amount to meet the applied demand of the electronic industry.
