제1도는 본 고안의 일부를 절제한 상태의 단면도.1 is a cross-sectional view of a state in which a part of the present invention is removed.

1 : 요오크 2 : 절연체1: yoke 2: insulator
2' : 통공 3,3' : 자석이다.2 ': through hole 3,3': magnet.
본 고안은 원주형 자석과 안테나가 양극통측면으로 나오도록 설치한 마그네트론에 있어서, 요오크를 음극으로 구성하되, 이를 절연체로 감싸도록 하여 절연구조 및 자기효율을 높힐 수 있도록 마그네트론에 관한 것이다.The present invention relates to a magnetron in which a magnet and an antenna are installed to come out of the anode cylinder side, and the yoke is configured as a cathode, and the insulation structure and magnetic efficiency are increased by enclosing the yoke with an insulator.
종래의 마그네트론은 요오크가 양극측으로 구성되어 있어 음극측에 삽입되어 있는 자석과는 필연적으로 절연을 시켜야만 했다.In the conventional magnetron, the yoke is configured on the anode side, so it is inevitable to insulate the magnet inserted into the cathode side.
따라서, 요오크와 자석 사이에 절연물을 삽입하고 있으며, 이는 양측 자석의 자기회로를 구성시켜 주는 역할을 하는 요오크의 자기회로에 일종의 자기저항을 삽입한 것과 같은 상태가 되어 충분한 자기효율을 얻을 수 없었다.Therefore, an insulator is inserted between the yoke and the magnet, which is equivalent to the insertion of a kind of magnetoresistance into the magnetic circuit of the yoke, which serves to compose the magnetic circuits of both magnets, thereby obtaining sufficient magnetic efficiency. There was no.
또한, 자석은 마그네트론이 작동할때 발생하는 열로 인하여 매우 고온으로 가열되므로 자석과 요오크 사이의 절연물이 고무의 성질을 갖고 있는 재질일 경우에는 열에 매우 약하여 절연이 파괴되기 쉽고 따라서 누설 자속이 증가되는 원인이 있었으며, 이를 해소시키기 위하여 내열성이 좋은 재질을 서용하게 되면 요오크와 자석 사이의 절연물은 가능한한 얇게 하여야 하는데, 내열성이 강한 재질일 경우 이온대립 방전현상이 일어나 장시간 마그네트론을 작동할 경우 절연 파괴가 발생할 우려가 있었다.In addition, since the magnet is heated to a very high temperature due to the heat generated when the magnetron is operating, if the insulation between the magnet and the yoke is a material having a rubber property, it is very weak to heat and thus the insulation is easily destroyed, thus increasing the leakage flux. If a heat resistant material is used to solve this problem, the insulation between the yoke and the magnet should be made as thin as possible.In the case of a strong heat resistant material, ion opposing discharge occurs, and the insulation breakdown when the magnetron is operated for a long time. There was a risk of this.
본 고안은 요오크를 양극측으로 구성함으로서 많은 문제점이 야기되는 것을 해소하기 위한 것으로 요오크를 음극으로 구성하되, 이를 절연체로 감싸주도록 구성한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to solve that many problems caused by configuring the yoke on the anode side, but to configure the yoke as a cathode, it is configured to surround it with an insulator as described in detail by the accompanying drawings as follows.
즉, 측방향에 안테나(4)를 설치하여 이를 중심으로 절연세라믹(5), 양극통(6), 필라멘트 플러그(7), 자석(3)(3')을 상·하로 대칭되게 형성하여 이의 외부에 요오크를 형성한 것에 있어서, 요오크(1)를 음극으로 구성하여 이의 표면에 내열성이 좋은 절연체(2)를 복착시키되 절연체(2)의 하부 내측에 통공(2')을 천설하여 이 부분에서만 자석(3')과 요오크(1)가 직접 접촉되도록 구성하여서 된 것이다.That is, the antenna 4 is installed in the lateral direction, and the insulating ceramic 5, the anode cylinder 6, the filament plug 7, and the magnets 3, 3 'are symmetrically formed up and down symmetrically. In the case where the yoke is formed on the outside, the yoke 1 is constituted by a cathode, and a surface of the insulator 2 having good heat resistance is deposited on the surface thereof. The magnet 3 'and the yoke 1 are configured to be in direct contact with each other only.
이상과 같은 본 고안은 음극인 요오크(1)의 표면을 내열성이 좋은 절연체(2)로 감싸도록 함으로서 요오크(1)를 음극으로 구성하더라도 고열에 의한 위험성을 방지시키고 이온대립방전 현상이 일어나지 않으며, 요오크(1) 표면의 절연체(2)에 형성된 통공(2')에 의하여 요오크(1)와 자석(3')이 접촉토록 함으로서 소정의 전류가 흐르도록 하여 전기적으로 단락되지 않도록 한 것으로 자석(3)(3')과 요오크(1)가 공히 음극이 되는 것이다.The present invention as described above wraps the surface of the yoke 1, which is a cathode, with an insulator 2 having good heat resistance, thereby preventing the risk of high temperature and causing ion opposing discharge even if the yoke 1 is composed of a cathode. In addition, the yoke 1 and the magnet 3 'are brought into contact by the through holes 2' formed in the insulator 2 on the surface of the yoke 1 so that a predetermined current flows so as not to be electrically shorted. The magnets 3, 3 'and the yoke 1 are both cathodes.
이에 따라 자기효율을 증가시키고 종래에 비하여 비교적 소형의 자석을 사용할 수 있으며, 요오크(1)를 음극의 고압측으로 구성하고 이의 표면에 내열이 좋은 절연체(2)로 감싸주므로서 자석(3)(3')과의 사이에서 절연파괴 현상을 제거하며 음극의 고열에 의한 위험성을 방지하고 내압불량을 감소시키는 등의 특징을 지닌 것이다.Accordingly, it is possible to increase the magnetic efficiency and to use a relatively small magnet as compared to the conventional one. The magnet 3 is formed by forming the yoke 1 on the high pressure side of the cathode and wrapping it with an insulator 2 having good heat resistance on its surface. 3 ') is to remove the insulation breakdown phenomenon, to prevent the risk of high temperature of the cathode and to reduce the breakdown pressure.
