Abstract: A magnetron for a microwave oven is provided that decreases noise in an ISM band by minimizing a size of a lower end shield, and thus, minimizing EMI generation. In the magnetron for the microwave oven, as a midpoint of a side lead hole is positioned inside a virtual circle formed by points positioned at a predetermined distance from a midpoint of the shield disc and a side lead is connected in a straight line, there are advantages that a further bending process is not generated and a defective rate that occurs in the manufacturing process of the shield disc may be decreased.

Abstract translation: 提供了一种用于微波炉的磁控管，其通过最小化下端屏蔽件的尺寸来降低ISM频带中的噪声，并因此最小化EMI产生。 在用于微波炉的磁控管中，由于侧导孔的中点位于由距屏蔽盘的中点预定距离处的点形成的虚拟圆的内部，并且侧导线连接成直线，所以存在 优点是不会产生进一步的弯曲过程，并且可以降低在屏蔽盘的制造过程中出现的缺陷率。
