In addition, the forming angle of the cathode holder support 1 is formed at 140 °, and thermal expansion by heater heat for electron beam radiation results in deterioration of radiation performance, which is a characteristic of the electron beam, and red and green (G), there was a problem that the overall characteristics of the color of the blue (B) deteriorated.
이에 따라 본 고안의 목적은 상술한 문제점을 감안하여 안출한 것으로, 전자빔이 방사되는 캐소우드 홀더 지지부의 구조를 개선하여 적(R), 녹(G), 청(B)으로 구성되는 전자빔 색의 밸런스를 유지하는 특성과, 캐소우드의 열팽창을 억제하여 전자빔의 방사특성을 향상시키도록한 전자총을 제공한다.Accordingly, an object of the present invention has been devised in view of the above-described problems, and improves the structure of the cathode holder support portion from which the electron beam is radiated to improve the structure of the electron beam color composed of red (R), green (G), and blue (B). An electron gun is provided to maintain the balance and the thermal expansion of the cathode to improve the radiation characteristics of the electron beam.
이와 같은 목적을 달성하기 위해, 본 고안은 캐소우드 어셈블리(Assembly)의 열팽창에 의한 변형을 방지하기 위하여 캐소우드 홀더의 중심선(X-X')보다 캐소우드 홀더 지지부의 포밍 형상을 높게 형성하고 캐소우드 홀더 지지부의 곡률반경(R)이 180°보다 크게하고, 캐소우드 홀더 지지부의 중심선(X-X')선상에서 스트라이트(Stright)부를 갖는 것을 특징으로 하는 전자총을 제공한다.In order to achieve the above object, the present invention forms the forming shape of the cathode holder support higher than the centerline (X-X ') of the cathode holder in order to prevent deformation due to thermal expansion of the cathode assembly. The radius of curvature R of the wood holder support is greater than 180 °, and the electron gun is provided having a streak on the center line (X-X ') of the cathode holder support.
이하, 상술한 특징을 구비한 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention having the above-described features will be described in detail.
제2도에 알 수 있는 바와 같이 본 고안에 의한 캐소우드 홀더 지지부구조는 비드글라스에 의해 하단부일측에 고정설치되는 캐소우드 홀더 지지부(10), 상기 캐소우드 홀더 지지부(10)의 상부에 안치되면서 열전자를 방출하는 캐소우드(30)를 삽입 고정하는 캐소우드홀더(20)로 이루어진다.As can be seen in Figure 2 the cathode holder support structure according to the present invention is fixed to the cathode holder holder 10, which is fixed to one side of the lower end by the bead glass, while being placed on the upper portion of the cathode holder support 10 A cathode holder 20 is inserted into and fixed to the cathode 30 emitting hot electrons.
캐소우드 홀더 지지부(10)는 하부를 비드글라스에 함몰될 수 있도록 수평으로 형성하고, 중앙부위에는 히터에 의한 가열로서 열전저를 방출하는 캐소우드(30)가 안정적으로 안치될 수 있도록 반원형 형태로 형성한다. 이때 캐소우드 홀더(20)를 지지해주는 캐소우드 홀더 지지부(10)의 포밍(Foming)형상을 캐소우드 홀더의 중심선(X-X')보다 높게하여 중심선(X-X')선상에서 스트라이트부를 갖도록 하며 곡률반경(R)을 180°이상으로 한다. 캐소우드 홀더(20)는 열전자를 방출하는 캐소우드(30)를 삽입할 수 있도록 원통으로 형성되며 상기 캐소우드 홀더 지지부(10)의 상부에 안치된다.The cathode holder support 10 is formed horizontally so that the lower portion can be recessed in the bead glass, and in the center portion is formed in a semi-circular shape so that the cathode 30 for releasing the thermal electrode by heating by the heater can be stably placed. do. At this time, the foaming shape of the cathode holder support 10 for supporting the cathode holder 20 is higher than the center line (X-X ') of the cathode holder so that the stripes are formed on the center line (X-X'). The radius of curvature (R) is to be 180 ° or more. The cathode holder 20 is formed in a cylindrical shape so as to insert the cathode 30 for emitting hot electrons and is placed on top of the cathode holder support 10.
이하, 본 고안에 따른 바람직한 실시예의 작용 및 효과를 설명한다.Hereinafter, the operation and effect of the preferred embodiment according to the present invention.
캐소우드 홀더 지지부(10)의 중앙상부에 캐소우드 홀더(20)를 안정적으로 안치시켜 고정한 후, 상기 캐소우드 홀더(20)내에 히터가 삽입된 캐소우드(30)을 삽입하여 레이저로 용접고정시킨다. 이후 캐소우드 홀더 지지부(10)의 양측을 야견대를 이용하여 비드글라스(Bead Glass)로 고정시킨다. 이때 캐소우드 홀더(20)를 지지해주는 상기 캐소우드 홀더 지지부(10)의 상단부 포밍 형상을 상기 캐소우드 홀더(20)의 중심선(X-X')보다 높게 형성되고, 상기 캐소우드 홀더(20)를 지지하는 상기 캐소우드 홀더 지지부(10)의 곡률반경(R)이 180°이상으로 형성되며, 또는 상기 캐소우드 홀더 지지부(10)의 중심선(X-X')선상에서 스트라이트(Stright)부를 갖도록 형성되어 캐소우드 홀더를 지지하여 주므로 전자빔 방사에 의한 캐소우드 홀더의 열팽창을 억제하여 적(R), 녹(G), 청(B)으로 구성되는 전자빔 색의 밸런스를 유지하는 특성과 전자빔의 방사특성을 향상시키게 된다.After the cathode holder 20 is stably settled and fixed on the upper portion of the cathode holder support 10, the cathode 30 inserted with the heater is inserted into the cathode holder 20 to be fixed by welding with a laser. . After that, both sides of the cathode holder support 10 are fixed with bead glass using a nightstand. At this time, the upper end forming shape of the cathode holder support 10 for supporting the cathode holder 20 is formed higher than the center line (X-X ') of the cathode holder 20, the cathode holder 20 The radius of curvature (R) of the cathode holder support 10 for supporting the is formed to be 180 ° or more, or the streak (Stright) on the center line (X-X ') line of the cathode holder support 10 It is formed so as to support the cathode holder, thereby suppressing thermal expansion of the cathode holder by electron beam radiation to maintain the balance of the color of the electron beam composed of red (R), green (G), and blue (B) and electron beam.
