이와 같이 배설된 고전압발생기는 보빈(20)에 의해 1,2차코일(5,11) 및 1,2차코어(1,3)가 절연되고, 따라서, 상기 1,2차코일(5,11)의 외측에 별도의 절연지를 외감시키지 않고, 1차코일(5)에 마이카시트를 감싸는 작업을 하지 않게 됨으로써, 공정수를 줄임과 동시에 절연지의 재료비를 절감시키고, 터미널(21)이 부착된 터미널지지대(23)를 체결나사(25)에 의해 간단히 1,2차코어(1,3)에 나합시킴에 따라 터미널 결합작업을 용이하게 한다.The high voltage generator thus disposed is insulated from the primary and secondary coils 5 and 11 and the primary and secondary cores 1 and 3 by the bobbin 20, and thus the primary and secondary coils 5 and 11. By not covering the outer side of the outer insulation paper) and wrapping the mica sheet in the primary coil (5), the process number is reduced and the material cost of the insulation paper is reduced, and the terminal 21 is attached to the terminal. The support 23 is easily screwed into the primary and secondary cores 1 and 3 by the fastening screw 25 to facilitate the terminal coupling operation.

상술한 바와 같이 본 발명에 의한 전자렌지용 고전압발생기의 절연장치에 의하면, 절연구조를 간단하게 함에 따라 절연지를 감싸는 작업을 줄이게 되어 공정수를 줄임과 동시에 절연지의 재료비를 절감시키고, 터미널의 결합작업을 용이하게 할 수 있다는 매우 효과적인 발명이다.As described above, according to the insulator of the high voltage generator for a microwave oven according to the present invention, as the insulation structure is simplified, the work of wrapping the insulating paper is reduced, thereby reducing the number of processes and reducing the material cost of the insulating paper.
