Abstract: A transformer structure having double-axis iron core is disclosed. The iron core structure mainly includes an iron core main body that has a base. The base has a parallel salient side convex part furnished respectively at the two opposite side edge thereof, and has a chamfered part furnished respectively at the two end parts corresponding to the side convex part thereof. It utilizes two iron core main bodies to be oppositely combined. In association with different shapes of coil, it is capable of forming various transformer structures and possesses a variety of combination, and is capable of adapting to various requirements of the product.

Abstract: A super-thin filter structure mainly has a channel furnished in the iron core with a penetrating hole furnished in the middle section thereof; a truncated angle parts is furnished at the end angles of the iron core; a containing concave part for containing the iron core is furnished and a center seat having a penetrating hole is furnished at the center thereof for placing into the penetrating hole of the iron core; a wire-guiding channels is also furnished at the bottom of the base; an upper cover is placed into the channel, and a center salient part having a penetrating hole is capable of placing into the penetrating hole and touching the center seat making the upper cover to clip the iron core in coordination with the base; a wire-guiding channels together with the wire-guiding channels is capable of simultaneously providing the winding of a coil.
