が生じる。In such a transformer, the flanges on one side of the primary and secondary coil bobbins, which are respectively incorporated into the core, are assembled with their flanges facing each other, and the bass core is positioned between the outer surfaces of the flanges that butt and engage. At this time, if the position of the bus core is not accurately determined for each assembly, variations will occur in characteristics such as excitation inductance and residual inductance.

容易になる。。According to the present invention, a continuous annular upright wall protruding outward in the axial direction is provided on the outer surface of one side of each coil bobbin, and
When abutted, these upright walls form a space that accommodates part or all of the bath core. Since the wall is continuous, the bus core can be securely restrained in any direction, allowing for accurate positioning of each human body.71
1. Variations in characteristics are eliminated and assembly work becomes extremely easy. .

される。Referring to FIG. 1, in the embodiment shown here, the leakage transformer has an E-type core 1 as the primary and secondary cores.
The two middle legs of each E-shaped core 1 and the bore part 4 (FIG. 2) of the coil bobbin 3 are aligned with each other, and the coil bobbin 3 is positioned between the side legs 5 in a V shape. Each coil bobbin/3 has flanges 6 at both ends, and when assembled into the core, these = 1 flanges on the outside of the coil bobbin 3, >6
The transformer is assembled with the two faces facing each other. Bass core 7 is installed between Kula and Shiro, which face each other.

となっている。In order to position the bass core 7, each of the facing flages 6 is provided with a continuous annular upright wall 8 projecting axially outward from its outer surface to form a pocket for the bass core. The flat α11 shape of this upright wall 8 is
In the embodiment shown in FIG. 2, it is rectangular. Figure 3 ((
In the example shown, it has a cylindrical shape to match the disk-shaped bass core 7.

きわめて容易となる。These straight walls 8 constitute a space that accommodates part or all of the bass core 7 when the bobbin 3 is butted against each other. In this way, the bus core 7 is constrained in all directions by the upright wall 8 and the outer surface of the flange and is precisely positioned 1, and the set s'/,! Since accurate positioning can be achieved simply by placing the bass core 7't on h' and + on the throat (, +), the task of setting -'/: 1'l; becomes extremely easy.
