る。 As shown in FIG. 6, the holes 35 and 36 for passing the external lead wires provided in the first flange 32 and the second flange 33 of the secondary bobbin 12 are eccentric to each other in the lower and upper stages. Therefore, when the external lead wire 14 is forcibly bent by inserting the external lead wire 14 into the holes 35 and 36 as shown in FIG. The wire 14 is engaged with the holes 35 and 36, and becomes difficult to come off against external tensile force. In particular, the opening edges 66, 67, 68 other than the outer opening edge 65 of the hole 35 of the first flange 32 are formed at right angles without dropping the edges. By locking the wire 14 and using a silicone coated wire with a wire diameter of about 3 mm as the external lead wire 14, a sufficient elastic restoring force against bending is exerted, so that the external lead wire 14 can be reliably prevented from coming off. Further, as is clear from FIG. 6, the outer diameter of the protrusions 27, 28 of the primary bobbin 11 and the inner diameter of the winding drum 31 of the secondary bobbin 12 are formed to be approximately equal, and when these are fitted, the Next bobbin 11
The protrusions 27 and 28 are connected to the winding drum 31 of the secondary bobbin 12.
to prevent looseness between the bobbins 11 and 12, and to maintain a uniform distance between the primary coil 29 and the secondary coil 38. The provided external lead wire insertion hole 22 is formed so as to face the inner space of the large diameter portion 37 of the secondary bobbin 12 so that there is no problem in drawing out the external lead wire 13 of the primary coil 29. do.

The protrusion 28a and the lower protrusion 28b are formed on the outer circumferential surface of the winding drum 21 over an approximately 90° range, with discontinuous intervals 6 on both sides between them.
2 is also formed over an approximately 90° range, and a number of holes 22 for inserting lead wires are provided in a corresponding number to the discontinuous spaces 45 of the upper projection 28a.

1, secondary bobbin 12, and iron cores 2 and 3, this transformer is immersed upside down in a vacuum tank containing a filler such as a range, and vacuum impregnation is performed. The filler is iron core 3
It penetrates into the winding drum 31 of the secondary bobbin 12 from the gap 71 between the and the arc-shaped concave groove 59, and furthermore, in FIG.
2. The discontinuous spacing 61 between the protrusions 27, the spacing 73 on the surface of the primary coil 29, the discontinuous spacing 62 between the protrusions 28, and the spacing 74 on the surface of the non-wound portion 26 are sequentially penetrated into these spaces. Fill in the internal gap. At that time, the air in this internal space is drawn from the notch-shaped groove 42 to the iron core 2.
Since the air is evacuated to the outside through the gap 75 (shown in FIG. 1) between the curved surfaces of the bobbins 11 and 12, the filler can penetrate smoothly and reliably.

ガスを発生するアウトガスの問題がない。
According to the present invention, two flanges are molded with a gap between them, instead of being integrally molded into one piece.
Since holes with a slightly larger diameter than the external lead wire for passing the same external lead wire through each flange are provided eccentrically from each other, the external lead wire inserted through both holes is forcibly bent. As a result, the external lead wire is pressed against the corner of the hole opening by its own elastic restoring force, and does not shift in this hole even if pulled from the outside, and has a simple structure and effective prevention effect. The operation is easy because the external leads only need to be inserted through two holes. Since the external lead wires can be fixed in this way without using adhesive tape, there is no problem of outgassing in which the adhesive of the adhesive tape generates gas due to heat generated during voltage changing operation.
