Claims

[Scope of claim for utility model registration] A primary coil and two
In a transformer in which a pass iron core is arranged between the secondary coil and a heater winding is arranged next to the secondary coil, an insulator made of an electrical insulator and fitted between the central leg and the side legs of the iron core. The insulating member is provided with an inner insulating wall in contact with the central leg side of the iron core, and an outer insulating wall facing the inner insulating wall and in contact with the side leg side of the iron core. An end wall connecting the wall and the outer insulating wall is provided, and a locking protrusion that protrudes toward the mutually opposing surface of the inner insulating wall and the outer insulating wall is provided at the tip of at least one of the inner insulating wall and the outer insulating wall. established,
The secondary coil and the heater winding are housed in the winding accommodating portion surrounded by the end wall, the inner insulating wall, and the outer insulating wall, and the end face of the heater winding or the secondary coil is engaged with the locking protrusion. A transformer characterized in that the heater winding and the secondary coil are held by the insulating member by stopping them.
