본 고안은 음극접지형 마그네트론에 있어서, 고전압측인 방열체 주위를 감싸는 고정판을 절연체로 절연하고 방열체를 절연지지체로 고정시킴으로서 절연상태를 양호하게 할 수 있도록한 마그네트론에 관한 것이다.The present invention relates to a magnetron in which a cathode grounding magnetron is insulated from a fixing plate surrounding a high heat sink on the high voltage side with an insulator and the heat sink is fixed with an insulating support to improve the insulation state.

종래의 마그네트론은 고정판과 분리되도록한 방열체가 직접 결합되었거나 근접되어있어 방열체의 날카로운 부분에 의해 절연파괴현상을 일으키는 결점이 있었으며, 고주파 에너지의 일부가 절연봉착제를 투과하여 외부로 누설되는 것을 방지하고 양극의 고전압부위로 부터의 감전위험을 방지하기위하여 마그네트론 을 완전히 도전성 및 도자성체로 차폐하여 마그네트론의 동작시발생하는 고열을 충분히 냉각시키지 못하였으며, 특히 송풍기등을 사용하여 강제공냉을 시킬 경우는 더운 공기가 고정판 외부로 완전히 배출되지 못하고 고정판의 내벽에 반사되어 마그네트론의 냉각이 불량한 결점등이 있었다.Conventional magnetrons have a defect in that the heat dissipating element to be separated from the fixed plate is directly coupled or adjacent to cause insulation breakdown due to the sharp part of the heat dissipating element. In order to prevent the risk of electric shock from the high voltage part of the anode, the magnetron is completely shielded with conductive and magnetic material, so that the high heat generated during the operation of the magnetron is not sufficiently cooled. The hot air was not completely discharged to the outside of the fixing plate and reflected on the inner wall of the fixing plate, resulting in a poor cooling of the magnetron.

본 고안은 종래 이러한 결점을 해결하기위한 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다. 즉, 고정판(1)의 상단에 요오크(2)를 형성하여 이의 내부에 양극통(3), 자석(11), 절연세라믹(12), 필라멘트(13), 안테나(7)를 형성한 통상의 마그네트론에 있어서, 양극통(3)의 외측에 방열체(4)를 형성하고 이의 상단으로 특정한 고주파의 λ/4길이의 외측 금속원통체(5)를 일체로 설치하며 이의 내부에 안테나(7)를 감싸는 내측금속원통체(6)를 형성하고 이의 상단으로 안테나 봉지절연체(8)를 설치하는 한편 요오크(2)와 외측금속원통체(5)를 절연토록 이들사이에 절연체(9)를 형성하며 방열체(4)와 고정판(1)의 측면과 저면부에 열전도성이 낮은 절연지지체(10)(10')(10")를 각각 설치하여서 된 것으로 미설명부호 14는 가스킷, 15는 음극도입선, 16은 고압도입선, 17은 음극단자, 18은 절연물이다.The present invention is to solve this drawback in the prior art described in detail by the accompanying drawings as follows. That is, the yoke 2 is formed at the upper end of the fixed plate 1, and the anode cylinder 3, the magnet 11, the insulating ceramic 12, the filament 13, and the antenna 7 are formed inside thereof. Magnetron, in which the heat sink 4 is formed on the outside of the anode cylinder 3, and at the upper end thereof, the outer metal cylinder 5 of a specific high frequency λ / 4 length is integrally installed and the antenna 7 is formed therein. The inner metal cylindrical body (6) enclosing the () is formed and the antenna encapsulation insulator (8) is installed at the upper end thereof, while the insulator (9) is interposed between the yoke (2) and the outer metal cylindrical body (5). Formed by installing insulating supports 10, 10 'and 10 ", respectively, at the side and bottom of the radiator 4 and the fixing plate 1, respectively. Cathode lead wire, 16 high pressure wire, 17 negative electrode terminal, 18 is an insulator.

이상과 같이 구성된 본 고안은 고압측인 방열체(4)를 일체로 구성하고 그 외측을 완만하게 하므로서 절연파괴를 방지하고, 고정판(1)을 절연지지체(10)(10')(10")로 절연하므로서 고압으로 부터의 감전위험 및 절연파괴를 방지하며 내. 외측금속원통체(6)(5)를 특정한 고주파의 λ/4길이로 하므로서 특정주파수의 고주파 누설을 방지할 수 있도록 한 것이다.The present invention constituted as described above is configured to integrally constitute a high-pressure radiator 4 and to smooth the outside thereof to prevent breakdown, and to fix the fixing plate 1 to the insulating supports 10, 10 ', 10 " It prevents the risk of electric shock and insulation breakdown from high voltage by insulating the inner and outer metal cylinders (6) (5) to λ / 4 length of specific high frequency to prevent high frequency leakage of specific frequency.

또, 고압측인 외측금속원통체(6)와 요오크(2)를 절연체(9)로 절연하고 자석(11)은 요오크(2)의 내측에 완전히 밀착토록하므로서 자기회로의 구성이 양호하고 누설자속이 감소되어 자기효율이 증가되며 음극도 입선(15)을 전기적으로 부착하여 외부로 용이하게 표출토록 하고 마그네트론의 냉각에 필요한 송풍로에 장애물이 없어지므로 냉각효율이 매우 좋은잇점을 지닌 것이다.In addition, since the outer metal cylinder 6 and the yoke 2 on the high pressure side are insulated from the insulator 9, the magnet 11 is brought into close contact with the inside of the yoke 2, and the structure of the magnetic circuit is good. The leakage flux is reduced, the magnetic efficiency is increased, and the negative electrode also has the advantage that the cooling efficiency is very good because it is electrically attached to the inlet line 15 so that it can be easily exposed to the outside and there is no obstacle in the blower path required for cooling the magnetron.
