悪く、高価につく原因となっていた。Problems to be Solved by the Invention In the conventional method, when liquid thermosetting resin is poured into the insulating case 3 under reduced pressure and degassed, air bubbles in the resin are released from the surface of the exposed resin part. However, since the insulating case 3 and the fitting part of the coil were in close contact with each other, and there was no exposed part of the resin at the bottom of the coil, it was very difficult to remove the bubbles. As a result, voids remain in the resin and in the coil, causing poor insulation, resulting in very bad results in terms of reliability and defective rate of products as high-voltage transformers, resulting in poor yields and high costs. was.

られたことにょシ脱泡が非常に容易となる。Effect By providing a groove in a part of the insulating case that is in close contact with the coil, the resin is exposed at a lower area compared to the conventional case where the resin at the bottom of the coil was not exposed at all. In particular, defoaming becomes extremely easy.
この結果、樹脂内およびコイル内にボイドが残ることが
なくなり高信頼性を確保することができることになる。As a result, no voids remain in the resin or the coil, and high reliability can be ensured.
