In addition, the primary coil 5 is to reduce the number of processes by removing the work surrounding the separate mica sheet, the bobbin 30 is polyphenylene sulfide (P, P, S) or poly butylene It is molded from the same material as terephthalate (P, B, T).

다음은 이와 같이 구성된 본 발명의 일실시예에 의한 전자렌지용 고전압발생기의 절연장치의 작용 및 효과에 대해서 설명한다.Next will be described the operation and effect of the insulation device of the high voltage generator for a microwave oven according to an embodiment of the present invention configured as described above.

조립 방법에 대해서 설명하면, 도선(5a)을 권회시킨 1차코일(5)의 일측에 절연지(P)를 감싸고, 필라멘트코일(7)의 외측에 절연지를 감싸고, 패스코어(9)의 일측에 절연지(P)를 감싸고, 2차코일(11)의 일측에 절연지(P)를 감싼 후, 차례로 적층시키고 상기와 같이 적층된 1차코일(5), 필라멘트코일(7), 패스코어(9), 2차코일(11)의 양측에 ㄴ자로 몰딩된 보빈(30)을 각각 배치시킨 후에 1차코어(11)의 내측으로 삽입한다.When the assembly method is described, the insulating paper P is wrapped on one side of the primary coil 5 on which the conducting wire 5a is wound, the insulating paper is wrapped on the outside of the filament coil 7, and on one side of the pass core 9. Wrap the insulating paper (P), wrap the insulating paper (P) on one side of the secondary coil (11), and then sequentially laminated and stacked as described above primary coil (5), filament coil (7), pass core (9) After arranging the bobbins 30 molded by the letter N on both sides of the secondary coil 11, the inner core 11 is inserted into the primary core 11.

상기와 같이 보빈(30) 및 각각의 절연지(P)가 일측에 외감된 1차코일(5), 필라멘트코일(7), 패스코어(9), 2차코일(11)이 1차코어(1)에 삽입되면, 2차코어(3)를 덮어 용접하고, 녹스는 것을 방지함과 동시에 소음을 감소시키도록 함침제가 충진된 함침조에 담근 후 꺼내어 건조시킨다.As described above, the primary coil 5, the filament coil 7, the pass core 9, and the secondary coil 11 having the bobbin 30 and each insulating paper P wound on one side thereof are the primary core 1. ), The secondary core (3) is covered and welded, soaked in an impregnated tank filled with impregnant so as to prevent rust and reduce noise, and then take out and dry.

건조가 다되면, 보빈(30)의 일측에 절곡 형성된 터미널고정부(30a)에 체결수단(31)을 이용하여 터미널(13)을 나합시키고, 인출된 필라멘트코일(7)을 상기 고정수단(40)인 걸림턱(41)에 걸어준다. 상기와 같이 조립된 고전압발생기를 전자렌지의 본체의 내부 일측에 고정시킨 후, 걸림턱(41)에 고정되어 인출된 필라멘트코일(7)을 타 전자부품에 접속시킨다.When the drying is finished, the terminal 13 is screwed to the terminal fixing portion 30a formed at one side of the bobbin 30 using the fastening means 31, and the drawn filament coil 7 is fixed to the fixing means 40. Hang on the jaw (41). After the high voltage generator assembled as described above is fixed to one inner side of the main body of the microwave oven, the filament coil 7 fixed to the locking jaw 41 and drawn out is connected to another electronic component.

The secondary cores 1 and 3 are prevented from contacting each other, and therefore, the filament coil 7 is prevented from generating internal pressure to ignite. In addition, since the filament coil 7 does not cover a separate tube for preventing the internal pressure generation, the filament coil 7 has an effect of reducing the number of work processes as well as the material cost.

상기에 있어서, 걸림턱(41)이 보빈(30)의 터미널(13)이 부착된 터미널고정부(30a)에 배설된 것을 예로 들어 설명하였으나, 이에 한정된 것은 아니면, 제6도에 도시한 제2실시예 따라 보빈(30)의 측면부 일측에 형성시켜 필라멘트코일(9)을 고정시킬 수도 있다.In the above description, the locking jaw 41 has been described as an example of being disposed in the terminal fixing part 30a to which the terminal 13 of the bobbin 30 is attached. However, the present invention is not limited thereto. In some embodiments, the filament coil 9 may be fixed to one side of the bobbin 30.

상술한 바와 같이 본 발명에 의한 전자렌지용 고전압발생기의 절연장치에 의하면, 절연재인 보빈의 일측에 필라멘트코일을 고정시키는 걸림턱을 배설하여 상기 필라멘트코일이 코어와 접촉되어 내압이 발생되어 발화되는 것을 방지할 수 있고, 필라멘트코일에 튜브를 피복시키지 않게 되어 작업공정수를 줄임과 동시에 재료비를 절감시킬 수 있다.As described above, according to the insulator of the high voltage generator for a microwave oven according to the present invention, by arranging a catching jaw to fix the filament coil to one side of the bobbin as an insulating material, the filament coil is in contact with the core to generate internal pressure to ignite. It can prevent and do not coat the tube on the filament coil, which can reduce the number of working steps and at the same time reduce the material cost.
