Claims

[Scope of claim for utility model registration] A primary coil and two
In addition to placing the pass iron core between the next coil,
In a transformer in which a heater winding is arranged next to the secondary coil, a first insulating member made of an electrical insulator and fitted between the center leg and the side leg of the E-shaped core; and a second insulating member that overlaps the first insulating member and is fitted between the central leg and the side legs, and the first insulating member has the heater winding wound thereon. A winding frame portion to be rotated and a pass core accommodating portion that covers the pass core are integrally provided, and the second insulating member includes an inner insulating wall located on the center leg side of the E-type core, and an inner insulating wall located on the center leg side of the E-shaped core; An outer insulating wall located on the side leg side of the shaped iron core and an end wall connecting these inner insulating walls and outer insulating walls are provided, and the winding housing section surrounded by these inner insulating walls, outer insulating wall, and end wall is provided with the above-mentioned A secondary coil is fitted therein, and the outer insulating wall is further provided with a locking protrusion that protrudes toward the inner insulating wall and engages with a part of the first insulating member.
