Claims

[Scope of utility model registration request]

(1) In a microwave oven transformer in which a filament coil is disposed between a primary coil and a secondary coil that are fitted to an iron core, insulation of the secondary coil and filament coil with respect to the iron core, and the secondary coil A sheet of insulating paper for insulating between the filament coil and the filament coil was placed over one end surface of the secondary coil on the primary coil side, and had a window in the center facing the fitting hole of the secondary coil. 1st
an insulating part, a second insulating part which is provided integrally and continuously at both ends of the first insulating part and covers the outer peripheral side surface of the secondary coil, and a second insulating part which is provided integrally and continuously at the tips of these second insulating parts. A third coil that covers one end surface of the secondary coil and the other end surface on the opposite side.
The fourth insulating part includes an insulating part and a fourth insulating part that is integrally provided at the tips of the third insulating parts and forms a cylindrical part that covers the inner circumferential surface of the fitting hole and projects from the window. A transformer for a microwave oven, characterized in that the filament coil is fitted into a protruding portion of the cylindrical portion.

(2) Utility model registration In the statement of claim (1), the insulating paper is opened and folded in a double-fold shape to form the window and to form a space between the insulating paper and the first insulating part. A transformer for a microwave oven, characterized in that it has an integral holding part that clamps the filament coil.
