The wound core of a transformer to which a cylindrical coil bobbin is applied has the shape shown in FIGS. Some have a letter-shaped or multi-stage cross-sectional shape. That is, the wound cores 1 and 1' shown in FIGS. 5 and 6 are obtained by preparing in advance a plurality of strips having excellent magnetic properties and having different width directions, and winding the strips according to a shape. This wound core 1, 1'
On the other hand, a cylindrical coil bobbin 2, which has been divided into two in advance, is pressed against the pressure contact surface 3, and by rotating this coil bobbin 2 with respect to the winding core 1, the winding wire (not shown) of the coil bobbin 2 is rotated. It is designed to be applied.

has a rounded shape. In addition, coil bobbin 2
The stepped portions X 9 to X 12 that do not abut are also rounded, but these portions may be at right angles. In this way, by making the stepped portions X 1 to X 8 rounded, it is unlikely that the inner surface of the coil bobbin 2, especially its contact portion 3, will get caught or that it will be impossible to press the coil bobbin 2. . It also becomes possible to increase the effective area of the cruciform cross-section, thus contributing to the miniaturization of the transformer.

has a rounded shape. In this case as well, the stepped portions Y 13 to Y 20 that do not contact the coil bobbin 2 are also rounded, but these portions may be at right angles. In this way, by making the stepped portions Y 1 to Y 12 rounded, the inner surface of the coil bobbin 2,
In particular, it is rare that the pressure contact portion 3 gets caught or that the coil bobbin 2 becomes impossible to pressure contact.

FIG. 1A is a plan view of a material for explaining an embodiment of the method for cutting out the band material for the cruciform cross-section wound core shown in FIG. 7 according to the present invention. In FIG. 1A, edges 41a and 4 on both sides of a material 41 having straight edges are shown.
1b remains straight and is cut out along one predetermined curve 42. Thereby, two continuous strips 1 are obtained. In this case, one row of uneven portions of the strip 1 corresponds to one example of uneven portions of the strip 1, thereby increasing the utilization probability of the material. And location 4
Each strip 1 is obtained by cutting 3.

従つて、上述の半円は半楕円形状である。 The basic idea of manufacturing the cross-shaped cross section of FIG. 1A is to draw semicircles one on top of the other as shown in the figure, and determine the pattern of the cutout lines 42 so that they touch each other. However, in reality, the length direction of the cut out strip material 1 is about 500 times the width direction,
Therefore, the semicircle mentioned above has a semi-elliptical shape.
第１Ａ図のごとく帯材を切抜くと、素材４１の
使用効率はほぼ100％である。 When the strip material is cut out as shown in FIG. 1A, the usage efficiency of the material 41 is approximately 100%.

とにより各帯材１′が得られる。 FIG. 2 is a plan view of a material for explaining another embodiment of the method for cutting out the multi-section cross-section wound core strip material of FIG. 8 according to the present invention. In FIG. 2, edges 41a and 41b on both sides of a material 41 having straight edges are shown.
remains straight and is cut out along one predetermined curve 42. This results in two consecutive strips 1'
get. In this case as well, the uneven portions of one example of the strip material 1' correspond to the uneven portions of one row of the strip material 1', thereby increasing the utilization efficiency of the material. However, the shaded portions are truncated, and therefore the usage efficiency of the material 41 is slightly reduced. Each strip 1' is then obtained by cutting at the location 43'.
