no. 1 Embodiment approach
[0051] figure 1 It is an exploded perspective view of the transformer of the first embodiment. figure 2 yes figure 1 Completed perspective view of the transformer. image 3 yes figure 2 Front view (a), side view (b) of the transformer. Figure 4 yes figure 2 F-F cutaway view of the transformer. Figure 5 from below figure 2 perspective view of a transformer. Image 6 yes figure 1 Modification of the magnetic core of the transformer.
[0052] exist Figure 1 to Figure 6 Among them, the transformer 1 of this embodiment has: a bobbin 20 molded from an insulating resin, a coil 2 wound on the bobbin 20, and a magnetic core 10 placed on the bobbin 20. A horizontal type that is configured by lowering the height while lying on the ground.
[0053] The bobbin 20 has: a bobbin portion 21 around which a plurality of coils 2 are wound, a substantially circular flange portion 22 provided at both ends of the bobbin portion 21 and protruding toward the outer periphery of th...
no. 2 Embodiment approach
[0066] Figure 7 It is an exploded perspective view showing the transformer of the second embodiment. Figure 8 yes Figure 7 completed stereogram. Figure 9 yes Figure 8 Front view (a), side view (b) of the transformer. Figure 10 from below Figure 8 Completed perspective view of the transformer.
[0067] exist Figure 7 to Figure 10 Herein, the same components as those in the first embodiment are assigned the same reference numerals, and redundant descriptions are omitted.
[0068] In the second embodiment, the difference from the first embodiment is that only the side magnetic legs 11 are raised instead of the V-shaped side magnetic legs and the V-shaped terminal block in side view. Figure 9 As shown, the amount S of the lower part of the two ends 13 of the substantially quadrangular side magnetic legs and the lower part of the two ends of the magnetic legs 14 is increased upward, and the two ends 13 of the side magnetic legs 11 and the upper parts of the two ends...
no. 3 Embodiment approach
[0071] Figure 11 It is an exploded perspective view showing the transformer of the third embodiment. Figure 12 yes Figure 11 Front view (a), side view (b) of the completed transformer. Figure 13 from below Figure 11 Perspective view of the completed transformer.
[0072] exist Figure 11 to Figure 13 Herein, the same reference numerals are assigned to the same components as those in the second embodiment, and overlapping descriptions will be omitted.
[0073] In the third embodiment, the difference from the second embodiment is that Figure 11 As shown, a step portion 16 is provided between the side surfaces 14A of the magnetic legs 14 at both ends opposite to the central magnetic legs 15 of the magnetic core 10 and the lower surfaces 14B of the magnetic legs 14 at both ends, and the lower surfaces 14B of the magnetic legs 14 at both ends are formed as The point where the inside is higher than the outside.
[0074] Even if this is done, the same effect as above can...
