본 고안은 전자렌지용 고주파 발생장치에 관한 것으로 특히 마그네트론의 입력부 구조를 개선하여 제조원가 절감과 생산성 향상을 꾀하도록 함에 주안점을 둔 것이다.The present invention relates to a high frequency generator for a microwave oven, and in particular, to focus on improving the structure of the input portion of the magnetron to reduce the manufacturing cost and productivity.

종래 마그네트론의 입력부 구조를 살펴보면 제1,2도에서와 같이 복수개의 배인을 부착한 원통형 몸체(10)내에 필라멘트(3)가 위치하고, 그 하방에는 상기 필라멘트 지지를 위한 금속재 센터리드(43')와 사이드 리드(5')가 위치하게 되는데 상기 각 리드의 하단부위는 세라믹(6')을 관통하여 하방 돌출되어 있다.Referring to the structure of the input portion of the conventional magnetron, as shown in FIGS. 1 and 2, the filament 3 is positioned in the cylindrical body 10 to which the plurality of vanes are attached, and below the metal center lead 43 'for supporting the filament. Side leads 5 'are positioned, and lower ends of the leads protrude downward through the ceramic 6'.

또한, 상기 세타라믹(6') 저면의 메탈라이즈 금속(7') (8')에는 72%은 합금으로 된 용접재를 이용하여 필라멘트단자(9') (10')가 접속되므로서, 외부로부터 공급된 전류가 필라멘트단자(9') (10')와 메탈라이즈 금속(7') (8')및 리드를 통해 필라멘트(3)로 흐르게 된다.Further, the filament terminals 9 'and 10' are connected to the metallized metals 7 'and 8' on the bottom of the ceramic 6 'using a welding material made of 72% silver alloy. An electric current supplied from the outside flows to the filament 3 through the filament terminals 9 'and 10' and the metallized metals 7 'and 8' and the leads.

마그네트론에 전류가 공급되면 팔라멘트(3)은 온도가 약 2,000℃정도로 상승하게 되는바 이에 대비하기 위하여 리드는 융점이 2,600℃인 매우 고가의 몰리브덴늄으로 제조하여 사용해 왔다.When the current is supplied to the magnetron, the filament 3 rises to a temperature of about 2,000 ° C. In order to prepare for this, the lead has been made of very expensive molybdenum having a melting point of 2,600 ° C.

그런데 마그네트론 작동시에도 상기 리드 하단부위의 용접재와의 접속부 실제온도는 약 300℃정도 밖에 되지않아 높은 내열성을 가지는 고가의 몰리브렌 늄으로 제조된 리드 하단부위를 세라믹(6')하방까지 연장하여 관통돌출 시킨 필요가 없음에도 불구하고, 이를 하방까지 신장시켜 줌으로서 제조원가가 매우 높아진다.However, even when the magnetron is operated, the actual temperature of the contact portion with the welding material at the lower end of the lead is only about 300 ° C, and the lower end of the lead made of expensive molybdenum having high heat resistance is extended to below the ceramic (6 '). Although it does not need to penetrate through, it extends it downward so that manufacturing cost becomes very high.

또한 필라멘트 단자는 세라믹(6')저면이 메탈라이즈 금속(7') (8')을 중간 개재 시켜놓고 용접해야 하므로 그 작업이 매우 번거롭고 불편한 문제점이 있었다.In addition, the filament terminal has a very troublesome and inconvenient problem because the bottom of the ceramic (6 ') has to be welded with the metallized metal (7') (8 ') in the middle.

따라서 본 고안의 목적은 상기와 같은 종래의 문제점을 해결함과 동시, 마그네트론 입력부구조를 개선하여 제조원가 절감과 생산성 향상을 제공함에 있는 것인바 이를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Therefore, the object of the present invention is to solve the conventional problems as described above, and to improve the structure of the magnetron input unit to provide a reduction in manufacturing cost and productivity, which will be described in detail based on the accompanying drawings.

도면 제4(a), 제4(b)도에서와 같이 세라믹(6)의 양측에 각기 단자삽입구멍(63) (64)을 관통 형성하고, 상측면 양측 오목부(61) (62)에는 각기 센터리드(4)와 사이드리드(5)의 하단부 삽입용 홈(64) (66)을 형성하면서 세라믹 상측에 분리 형성된 양측 오목부(61) (62)에는 상기 구멍 및 홈과 대향되는 부위에 구멍이 형성된 메탈라이징 금속(7) (8)을 각각 삽입 설치하였다.As shown in Figs. 4 (a) and 4 (b), the terminal insertion holes 63 and 64 are formed through the ceramic 6, respectively, and the upper side both recesses 61 and 62 are respectively formed. The recesses 64 and 66 for inserting the lower end portions of the center leads 4 and the side leads 5, respectively, are formed on both side recesses 61 and 62 separately formed on the upper side of the ceramic. The metallized metals 7 and 8 with holes formed therein were respectively inserted.

그후, 세라믹의 구멍(63) (64)에는 필라멘트단자(9) (10)를 하측으로부터 삽입시켜 그 상단시켜 그 상단부가 메탈라이징금속(7) (8)에 접촉되므로 결합 설치하며, 상부의 양측 홈(65) (66)으로는 각기 센터리드(4)와 사이드리드(5)의 하단부위를 삽입설치한뒤 용접재를 이용하여 메탈라이징 금속(7) (8)과 리드(4) (5) 및 필라멘트단자 (9) (10)를 완벽하고 견고하게 접착시켜 입력부를 구성하는 것이다(제3도 참조).Then, the filament terminals 9 and 10 are inserted into the holes 63 and 64 of the ceramic from the lower side thereof, and the upper ends thereof are brought into contact with the metallizing metals 7 and 8 so that the upper and lower sides thereof are joined to each other. Insert the lower end of the center lead (4) and the side lead (5) into the grooves (65) and (66), respectively, and then use metallized metals (7) (8) and leads (4) (5) using a welding material. ) And the filament terminals (9) and (10) are completely and firmly bonded to form an input unit (see FIG. 3).

이때 상기 필라멘트 단자(9) (10)의 세라믹 삽입부위는 원활한 삽입을 위하여 원기둥 형태로 하고, 하단의 전원 연결부위는 사각형으로 형성하여 접촉저항을 줄이도록 하는 것이 바람직하다.At this time, the ceramic insertion portion of the filament terminal (9) (10) is preferably in the form of a cylinder for smooth insertion, the lower end of the power connection portion is preferably formed to reduce the contact resistance.

이와같이 구성하므로서 양측리드(4) (5)와 필라멘트단자(9) (10)는 메탈라이징금속(7) (8)을 통해 전기적 접속이 행하여지며 이를 통하여 공급된 전원에 의한 마그네트론의 작동은 종래와 같이 이루어진다.In this configuration, both leads (4) (5) and filament terminals (9) (10) are electrically connected through metalizing metals (7) (8), and the operation of the magnetron by the supplied power is It is done together.

이상과 같이 리드(4) (5)의 하단부가 세라믹(6)을 관통하여 하향 돌출됨을 지양하고 메탈라이징 금속(7) (8)을 거쳐 홈(65) (66)내에 삽입되므로서 마그네트론 작동시 파라멘트(3)가 약 2,000℃로 상승하였을때 그로부터 리드에 전도된 열은 하단부를 통해 메탈라이징 금속(7) (8)과 세라믹(6) 내로 전달되어 대기중으로 방출된다.As described above, the lower end of the leads 4 and 5 is not projected downward through the ceramic 6 and inserted into the grooves 65 and 66 through the metalizing metals 7 and 8 so that the magnetron is operated. When the parameter 3 rises to about 2,000 ° C., the heat conducted from it to the leads is transferred through the lower end into the metalizing metal 7 and the ceramic 6 and released into the atmosphere.

또한 전원 연결용 필라멘트단자(9) (10)에는 리드로부터 직접 고열이 전달되지 않으므로 내열성이 비교적 낮은 철- 니켓 합금으로 제조 사용해도 무방하다.In addition, since high heat is not directly transmitted from the lead to the filament terminals 9 and 10 for power connection, it may be made of an iron-nickel alloy having a relatively low heat resistance.

이상과 같이 구성되고 작동되는 본 고안은 마그네트론 입력부 구조를 개선하여 리드의 길이를 종래의 것보다 짧게 형성하게 되므로 고가의 올리브덴늄이 절약되어 제조원가 절감뿐만 아니라, 필라멘트단자는 일반적으로 철- 니켓 합금으로 제조하여 세라믹의 구멍에 끼워지는 형태로 결합되므로서 종래의 용접접착 방식에 비해 결합 작업이 월등히 간편하고 수월해진 특징이 있다.The present invention, which is constructed and operated as described above, improves the structure of the magnetron input part and forms the lead length shorter than the conventional one, thus saving expensive olive dennium and reducing manufacturing cost, and the filament terminal is generally made of an iron-nickel alloy. It is characterized in that the coupling operation is much simpler and easier than the conventional welding method by being manufactured in the form of being fitted into the hole of the ceramic.
