본 고안은 마그네트론의 요크체결 장치에 관한 것으로, 특히 마그네트론의 조립공정시에 상, 하요크를 상호 결합하기 용이하도록 한 것이다.The present invention relates to a yoke fastening device of a magnetron, in particular, to facilitate the coupling of the upper and lower yokes in the magnetron assembly process.
전자렌지에 사용되는 마그네트론은 일종의 2극 진공관으로서 이는 제 1 도와 같이, 직열형 캐소드의 필라멘트(7)를 중심으로 방사상 복수개의 배인(2)를 가진 원통형 양극인 애노드(1)와, 상기 배인(2)과 필라멘트(7)사이에 필라멘트(7)에서 방출된 열전자가 축방향인가된 자속과 음극, 양극 사이에 형성된 전장으로 사이클로트론 운동을 하면서 전자기파를 발생하는 작용공간(8)과, 상기 작용중 축방향으로 균일하며 강한자속을 인가시켜 주기위한 상, 하 자석(5), 자극(4), 외부요크(6)등으로 이루어진 자기회로부로 구성되어 있으며, 상기 작용공간(8)에서 발생된 전자기파는 안테나피더(3), 안테나씰(11), 세라믹(9)등으로 구성된 출력부를 통해 외부로 유도되고 있다.The magnetron used in the microwave oven is a kind of two-pole vacuum tube, which is a cylindrical anode having a plurality of radial vanes (2) around a filament (7) of a linear cathode, as in the first diagram, and the vane ( Between the 2) and the filament (7) the working space (8) for generating electromagnetic waves while performing cyclotron motion with the electric field formed between the axially applied magnetic flux and the cathode and the anode axially applied to the hot electrons emitted from the filament (7), It is composed of magnetic circuit part consisting of upper and lower magnets (5), magnetic poles (4), external yoke (6), etc. to apply uniform and strong magnetic flux in the axial direction, and electromagnetic waves generated in the working space (8). The outside is led to the outside through the output consisting of the antenna feeder (3), antenna seal (11), ceramic (9).
그리고, 종래의 요부요크(6)는 상, 하부요크(61, 62)로 구성되어, 마그네트론 몸체와 자석(5)을 가운데로 하여 서로 대응결합된 상태로 체결하였으며, 여기서 그 체결부위 틈새를 없애면서 자기효율을 높여주기 위해서는 용접, 나사조임, 돌출결합부의 대응결합등 다양한 체결 방법이 실시되었다. 특히 돌출결합부에 대응결합체결 방법은 제 2a 도와 같이 상부요크(61)에는 구부림 절곡편(61a)과 끼움홈(61b)을 형성시키고 하부요크(62)는 상기 구부림 절곡편(61a)과 끼움홈(61b)에 대응결합하는 절곡편(62a)을 형성시켜 이들을 상호 결합시키거나, 또는 (b)와 같이 하부요크(62)의 단부에는 펀칭요홈(62b)을 마련하고 이 펀칭요홈(62b)에 맞춰결합되는 구부림편(61c)을 상부요크(61) 소정부위에 대향형성시킨 형태로 되어있었다.In addition, the conventional yoke yoke (6) is composed of the upper, lower yoke (61, 62), the magnetron body and the magnet (5) in the center of the mating state coupled to each other, where the gap between the fastening part is eliminated In order to increase the magnetic efficiency, various fastening methods such as welding, screwing, and mating of protruding joints were implemented. In particular, the corresponding coupling method of the protruding coupling portion forms a bending bent piece 61a and a fitting groove 61b in the upper yoke 61 as shown in FIG. 2A, and the lower yoke 62 is fitted with the bent bending piece 61a. Forming the bending piece 62a corresponding to the groove 61b to couple them to each other, or as shown in (b) is provided with a punching groove 62b at the end of the lower yoke 62 and the punching groove 62b The bent piece 61c to be fitted in conformity with the upper yoke 61 was formed to face each other.
그러나, 이러한 선행기술들에 있어서는, 용접방법의 경우 그 공정이 복잡함은 물론 체결부위외의 구조파 누설방지를 할 수가 없고, 나사이용의 경우 체결성은 좋지만 공정과 소요부품이 많아지고 치수관리가 어려우며, 상기 돌출부 이용의 경우에는 그 구조적 특성으로 인해 횡방향 압력을 가해야하므로 제조공정의 적용이 어렵고 그 체결성 및 기밀특성등을 양호히 확보하는 데 불리한등의 문제점들이 지적된다.However, in these prior arts, in the case of welding method, the process is not only complicated, but also prevents structural wave leakage other than the fastening part. In the case of using the protrusions, problems such as difficulty in applying the manufacturing process and securing the fastening property and the airtight property, etc. are pointed out because of the structural characteristics, which require lateral pressure.
본 고안의 목적은 상기와 같은 종래 기술의 문제점을 개선하고져 안출한 것이다.An object of the present invention is to solve the problems of the prior art as described above.
본 고안은 특히 마그네트론의 상부요크에는 펀칭요홈을 두고, 하부요크에는 이 펀칭요홈에 대응되며 지그로 벌려지는 대칭날개편을 구비시킨 구성을 특징으로 하는 것이다.The present invention is characterized in that the upper yoke of the magnetron is provided with a punching groove, the lower yoke corresponding to the punching groove and provided with a symmetrical wing piece that is spread with the jig.
이하에서 이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail below.
즉, 제 3 도는 본 고안의 이 적용된 상, 하부요크(61, 62)의 결합부위를 나타내었다.That is, Figure 3 shows the coupling portion of the upper, lower yoke (61, 62) of the present invention.
여기서는 상부요크(61)에 소정크기의 펀칭요홈(611)이 펀칭돌부(612)에 의해 형성되어지고, 하부요크(62)에는 상기 펀칭요홈(611)에 대응된 대칭날개편(621)이 구비된다.Here, a punching groove 611 of a predetermined size is formed in the upper yoke 61 by a punching protrusion 612, and the lower yoke 62 is provided with a symmetrical wing piece 621 corresponding to the punching groove 611. do.
상기 대칭날개편(621)은 그 단부에 각기 절곡턱(622)을 가지며 그 중앙에 삼각홈(623)과 도면중 그 하단부측에 벌림홈(624)이 형성되어져 있다.The symmetrical wing piece 621 has a bent jaw 622 at each end thereof, and a triangular groove 623 is formed at the center thereof, and an opening groove 624 is formed at the lower end side thereof in the drawing.
이러한 구성의 본 고안은 마그네트론의 상, 하부요크(61, 62)를 상호 결합할 경우 상부요크(61)에 마련된 펀칭요홈(611)을 겨냥하여 하부요크(62)의 대칭날개편(621)을 진입시키고, 삼각날개형의 지그(J)를 상기 펀칭요홈(611)내로 삽입하여 아래로 삼각홈(623)을 눌러주면, 대칭날개편(621)은 펀칭요홈(611)내에서 좌우 대칭되게 벌어지게 되며, 따라서 이 펀칭 요홈(611)을 이루는 펀칭돌부(612)의 상단부에서 대칭날개편(62a)의 절곡턱(622)은 확개된 상태로 맞물려 고정되어 진다.When the upper and lower yokes 61 and 62 of the magnetron are coupled to each other, the present invention has a symmetrical wing piece 621 of the lower yoke 62, aimed at the punching groove 611 provided in the upper yoke 61. When entering, insert the triangular wing jig (J) into the punching recess 611 and press the triangular groove 623 downward, the symmetrical wing piece 621 is symmetrically opened in the punching recess 611. Therefore, the bent jaw 622 of the symmetrical blade piece 62a at the upper end of the punching protrusion 612 constituting the punching groove 611 is engaged and fixed in an expanded state.
이때 벌림홈(624)은 상기 대칭날개편(621)을 지그로 벌려줄때 그 벌어짐 작용을 원활히 도와준다.At this time, the gaping groove 624 smoothly assists the gaping action when the symmetrical wing piece 621 is opened with a jig.
이러한 본 고안은 마그네트론의 상, 하부요크(61, 62)를 체결시킨 경우에 이들 상, 하부 요크(61, 62)의 종축방향에서 힘을 가하여 체결 고정시키게 되므로 결합방향과 동일한 힘을 가해줄 수 있어 그 체결성능을 양호히 유지할 수 있고, 단순한 지그의 종축방향누름으로 간단히 소정부위의 결합을 완성하므로 그 작업이 용이하며 따라서 자기 회로상의 자기누설등도 줄어들어 이러한 기기의 동작적 성능도 좋게하는 유익한 특징이 있는 것이다.When the upper and lower yokes 61 and 62 of the magnetron are fastened, the present invention may apply the same force as the coupling direction because the upper and lower yokes 61 and 62 are fastened and fixed in the longitudinal direction of the upper and lower yokes 61 and 62. It is possible to maintain the fastening performance well, and it is easy to work by simply completing the joining of a predetermined part by simply pressing the longitudinal axis of the jig, and thus the magnetic leakage on the magnetic circuit is also reduced, which is an advantageous feature to improve the operational performance of such equipment. Is there.
