Pulse transformer

The invention provides a pulse transformer, comprising a magnetic core composed of a first magnetic core body and a second magnetic core body, wherein winding wires are wound on the first magnetic core body in advance to form a corresponding winding coil, and then the first magnetic core body is mounted on the second magnetic core body so that the first magnetic core body and the second magnetic core body form a closed magnetic circuit, the winding coil comprises a first winding and a second winding, the first winding comprises two first winding wires, the first ends of the two first winding wires are respectively connected with a first electrode and a second electrode, the second ends of the two first winding wires are respectively connected with a third electrode and a fourth electrode, the second winding comprises two second winding wires, the first ends of the two second winding wires are respectively connected with fifth and sixth electrodes, the second ends of the two second winding wires are respectively connected with seventh and eighth electrodes. The start and tail ends of the two windings are both arranged on the same side of the first magnetic core body, and thus the insulation capability of primary and secondary windings can be improved and the requirement on magnetic core material can be reduced further.
