In addition, the winding portion 11 has a substantially tubular structure to provide a portion of the core 20, wherein the winding portion 11 has a first baffle 111 near the second outlet portion 13 and at least one second baffle 112 for distinguishing a winding area of the first winding 30 from a winding area of the second winding 40. The first baffle 111 is different from the second baffle 112, the second baffle 112 is designed to surround the winding portion 11, but the first baffle 111 is only disposed on a portion of the winding portion 11 and does not surround the winding portion 11. In addition, the second wire outlet portion 13 has a first inclined surface 131 facing the wire winding portion 11, a first partition 132 disposed on the first inclined surface 131, and a first stopper 134 disposed corresponding to the first stopper 111 and defining a wire passage 133 together with the first stopper 111.
