따라서, 세라믹기판(14)상에 돌출형성된 입력부(11)를 통하여 P1에 부착된 슬라이드볼륨(Volume)을 통해 포커스 전압의 출력이 결정되고, P2에 부착된 슬라이드 볼륨을 통하여 스크린 출력전압이 결정되는 것이다.Accordingly, the output of the focus voltage is determined through the slide volume attached to P 1 through the input unit 11 protruding on the ceramic substrate 14, and the screen output voltage is determined through the slide volume attached to P 2 . It is decided.
이때, 세라믹기판(14)상의 한정된 공간내에서 7-10㎸의 고전압에 의한 전위차에 의해 세라믹기판 표면으로 아아크방전 및 CPT 방전이 일어나게 되어 포커스 유니트가 파괴되는 경우가 빈번하게 발생되는 문제점이 있었던 것이다.In this case, arc discharge and CPT discharge occur on the surface of the ceramic substrate due to the potential difference due to the high voltage of 7-10 kV within the limited space on the ceramic substrate 14, and the focus unit is frequently destroyed. .
본 고안은 상기한 바와같은 종래의 문제점을 개선하기 위하여 안출된 것으로서 그 목적은, 포커스 유니트의 세라믹 기판요홈에 일정패턴으로 형성되는 콘덕터의 회로간 아아크 방전 및 CPT 방전에 의한 표면누설(leakage)을 방지토록 함은 물론, 제품자체의 신뢰성을 향상시킬 수 있는 FBT의 포커스 유니트를 제공하는 데 있다.The present invention has been made to solve the above-described problems, and its object is to provide surface leakage by arc discharge and CPT discharge between circuits of a conductor formed in a predetermined pattern in a ceramic substrate groove of a focus unit. In addition, the present invention provides a FBT focus unit that can improve the reliability of the product itself.
상기 목적을 달성하기 위한 기술적인 구성으로서 본 고안은, 포커스 유니트의 세라믹 기판상에 일정패턴의 요홈을 형성하여 상기 요홈내에 콘덕터로 형성되는 회로를 형성토록 하는 것이 특징이다.As a technical configuration for achieving the above object, the present invention is characterized in that a certain pattern of grooves are formed on a ceramic substrate of a focus unit to form a circuit formed of a conductor in the grooves.
이하, 첨부된 도면에 의거하여 본 고안을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 2 도 (a)는 본 고안의 포커스 유니트 기판의 요홈내로 일정패턴의 콘덕터가 형성된 상태를 도시한 평면구조도이고, 제 2 도 (b)는 본 고안인 세라믹 기판의 일부확대 사시도로서, 입력부(1) 및 그라운드(2)가 일정패턴으로 형성된 콘덕터(3)가 세라믹기판(4)에 형성되며, 각각의 라운드부에 포커스 전압출력부(5) 및 스크린전압 출력부(6)가 P1, P2지점을 기준으로 형성된다.FIG. 2 (a) is a plan view showing a state in which a conductor of a predetermined pattern is formed in the recess of the focus unit substrate of the present invention, and FIG. 2 (b) is a partially enlarged perspective view of the ceramic substrate of the present invention, wherein A conductor 3 having a constant pattern (1) and ground (2) is formed on the ceramic substrate (4), and the focus voltage output section (5) and the screen voltage output section (6) are formed at each round portion. 1 , formed on the basis of the P 2 point.
또한, 포커스 유니트의 세라믹기판(4)상에 일정패턴의 요홈(7)을 형성하여 이 요홈내에 상기 콘덕터(3)로 되는 회로를 형성토록 한 구성으로 이루어진다.In addition, a concave groove 7 having a predetermined pattern is formed on the ceramic substrate 4 of the focus unit so that a circuit serving as the conductor 3 can be formed in the concave groove.
상기와 같은 구조를 갖는 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention having the structure as described above are as follows.
제 2 도 (a) 및 (b)에 도시한 바와같이, 세라믹기판(4)의 요홈(7)내에 형성된 입력부(1)를 통해 P1의 포커스 전압출력부(5)를 통하여 포커스 전압이 출력되고, P2에 부착된 스크린전압 출력부(6)를 통해 스크린 출력전압이 발생된다.As shown in FIGS. 2A and 2B, the focus voltage is output through the focus voltage output part 5 of P 1 through the input part 1 formed in the recess 7 of the ceramic substrate 4. The screen output voltage is generated through the screen voltage output unit 6 attached to P 2 .
한편, 세라믹기판(4)의 콘덕터(3)에는 7-10㎸의 고압에 의한 전위차에 의해 아아크 혹은 CPT 방전이 발생될 경우, 상기 콘덕터(3)의 회로는 세라믹기판(4)의 요홈(7)내에 형성되고 기판 표면으로 돌출되지 않기 때문에 상기 방전현상에 의한 표면누설(leakage)이 유효하게 차단시킬 수가 있다.On the other hand, in the case where arc or CPT discharge occurs in the conductor 3 of the ceramic substrate 4 due to a potential difference due to a high voltage of 7-10 kV, the circuit of the conductor 3 is a recess of the ceramic substrate 4.
