Claims

[Scope of utility model registration request]

In a high frequency transformer for a microwave oven, which is configured by mounting a primary coil bobbin in which a primary coil is wound around an E-type ferrite core, a secondary coil bobbin in which a secondary coil is wound, and an I-type ferrite core, an L-shaped fin is attached to the primary coil bobbin. is formed so as to extend to both sides, and a flange is formed on the secondary coil bobbin adjacent to the L-shaped fin so as to fit into the L-shaped fin, and the flange and the L-shaped fin together form the secondary coil bobbin. A microwave oven characterized in that a gap is formed between the E-type ferrite core and the I-type ferrite core, and the gap ensures an insulating distance between the high voltage part of the secondary coil and both ferrite cores. High frequency transformer.
