Abstract

본 고안은 전자총 어셈블리의 개선된 캐소드 지지구조를 개시한다.The present invention discloses an improved cathode support structure of an electron gun assembly.

종래에는 지지편을 캐소드 홀더의 소정위치에 정합시킬 수 있는 수단을 구비하고 있지 못해 캐소드와 G1전극간의 간격 불일치가 야기되는 문제가 있었다.Conventionally, there is a problem that the gap between the cathode and the G1 electrode is caused because the support piece is not provided with a means for matching the support piece to a predetermined position of the cathode holder.

본 고안에서는 캐소드 홀더에 삽입홈을 형성하여 지지편의 접합부가 삽입되도록 함으로써 종래의 문제를 해결하였다.In the present invention solved the conventional problem by forming an insertion groove in the cathode holder to be joined to the support piece.

본 고안은 음극선관(cathode ray tube) 제조에 관한 것으로, 더 상세히는 전자총 어셈블리(electron gun assembly)의 캐소드를 지지하는 지지구조에 관한 것이다.The present invention relates to the manufacture of cathode ray tubes, and more particularly to a support structure for supporting the cathode of an electron gun assembly.

음극선관은 전자총 어셈블리에서 발사된 전자빔을 스크린(screen)상에 선택적으로 랜딩(landing)시킴으로써 화상을 표시하는 장치이다. 이러한 전자총 어셈블리는 전자를 방출하는 캐소드와, 방출된 전자를 집속(集束) 및 가속(加速)시키는 복수의 전극들이 순차적으로 배열되어 일체로 조립된 구성이다. 이와같이 캐소드 및 각 전극들을 일체로 결합하는 방법으로는 통상 결정화 유리(multiform glass)로 된 막대, 예컨대 비이드 글래스(bead glass)를 열연화(熱軟化)시켜 이에 전술한 요소(element)들을 압입(壓入)시킨 후 경화시키는 방법이 사용된다.A cathode ray tube is a device that displays an image by selectively landing an electron beam emitted from an electron gun assembly on a screen. Such an electron gun assembly has a configuration in which a cathode for emitting electrons and a plurality of electrodes for focusing and accelerating the emitted electrons are sequentially arranged and integrally assembled. As such, a method of integrally combining the cathode and the respective electrodes is typically performed by softening a rod made of crystalline glass, for example, bead glass, and indenting the aforementioned elements. After hardening, the method of hardening is used.

이에따라 각 전극 및 캐소드에는 비이드 글래스에 매립되어 이를 고정시켜 주기 위한 고정수단이 요구되는 바, 각 전극에는 매립편이 형성 또는 부착되나 캐소드는 매우 작은 직경의 원통형이므로 매립편의 형성이나 부착이 대단히 어렵다. 따라서 캐소드는 별도의 지지수단에 의해 비이드 글래스에 매립고정되는 것이 일반적이다.Accordingly, each of the electrodes and the cathode is buried in the bead glass is required for fixing means for fixing it, each electrode is formed or attached to the buried piece, but the cathode is a very small diameter cylindrical form or attachment is very difficult. Therefore, the cathode is generally fixed to the bead glass by a separate supporting means.

제1도에는 이러한 종래의 캐소드 지지구조를 도시하였다. 캐소드(K)는 이를 감싸도록 구성된 캐소드 홀더(cathode holder; 1)에 접합 지지되어 있고, 이 캐소드 홀더(1)는 양단이 비이드 글래스(B)에 매립된 지지편(support strap; 2)에 그 외주가 접합되어 있다.1 shows such a conventional cathode support structure. The cathode K is bonded and supported by a cathode holder 1 configured to surround it, and the cathode holder 1 is attached to a support strap 2 whose both ends are embedded in the bead glass B. FIG. The outer periphery is joined.

그런데 이와같이 캐소드(K)를 고정하는데 있어서 특히 고려해야 할 사항은 캐소드(K)와 G1전극(G1)간에 정확한 간격을 유지시키는 것인데, 종래의 지지구조는 이를 정확히 일치시키기가 대단히 어려운 문제를 안고 있었다. 즉 캐소드(K)와 G1전극(G1)간의 실제적인 간격은 캐소드(K)를 비이드 글래스(B)에 대해 지지하는 지지편(2)의 캐소드 홀더(1)에의 접합에 의해 결정되어지는 바, 종래에는 이들을 상호 정합(alignment)시킬 별다른 수단을 구비하고 있지 못하다. 이에따라 자칫 지지편(2)이 캐소드 홀더(1)의 원래의 접합위치를 벗어난 위치에 접합되게 되어 캐소드(K)와 G1전극(G1)간의 간격이 설계치를 벗어나 음극선관의 컷 오프(cut-off)특성 저하를 초래하게 된다. 그러므로 종래의 지지구조는 완성된 음극선관의 화질을 열화(劣化)시키는등 그 품위(品位)와 신뢰성을 보장할수 없었다.However, the particular consideration in fixing the cathode (K) is to maintain a precise distance between the cathode (K) and the G1 electrode (G1), the conventional support structure had a very difficult problem to match exactly. That is, the actual spacing between the cathode K and the G1 electrode G1 is determined by the bonding of the support piece 2 supporting the cathode K to the bead glass B to the cathode holder 1. In the prior art, there is no other means for aligning them. As a result, the support piece 2 is joined to a position beyond the original bonding position of the cathode holder 1, so that the gap between the cathode K and the G1 electrode G1 is out of the design value and cut-off of the cathode ray tube. This will cause deterioration of characteristics. Therefore, the conventional support structure cannot guarantee the quality and reliability, such as deteriorating the image quality of the completed cathode ray tube.

본 고안의 목적은 이러한 종래의 문제를 감안하여 지지편을 캐소드 홀더의 소정위치에 간단하고 정확하게 접합시킬 수 있는 전자총 어셈블리의 캐소드 지지구조를 제공하는 것이다.It is an object of the present invention to provide a cathode support structure of an electron gun assembly capable of simply and accurately joining a support piece to a predetermined position of a cathode holder in view of such a conventional problem.

이와같은 목적을 달성하기 위해 본 고안 캐소드 지지구조는 캐소드를 감싸도록 지지하는 캐소드 홀더와, 이 캐소드 홀더 외주를 접합하여 비이드 글래스에 매립되는 지지편을 구비하는 전자총 어셈블리의 캐소드 지지구조에 있어서, 캐소드 홀더의 외주에 지지편의 접합부가 삽입되는 삽입홈이 형성되어 구성되는 것을 특징으로 한다.In order to achieve the above object, the cathode support structure of the present invention is a cathode support structure of an electron gun assembly having a cathode holder supporting a cathode to be wrapped, and a support piece bonded to an outer circumference of the cathode holder and embedded in a bead glass, Characterized in that the insertion groove is formed is formed in the outer periphery of the cathode holder is inserted into the junction of the support piece.

이에따라 본 고안은, 지지편을 캐소드 홀더의 소정위치에 정확하게 접합할 수 있게되므로 캐소드와 G1전극간의 간격을 정확히 유지시킬 수 있게되어, 완성된 음극선관의 신뢰성 향상등에 효과를 발휘한다.Accordingly, the present invention enables the support piece to be bonded precisely to a predetermined position of the cathode holder, thereby making it possible to accurately maintain the gap between the cathode and the G1 electrode, thereby exerting an effect on improving the reliability of the completed cathode ray tube.

이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도 및 제3도에서, 본 고안에 의한 캐소드 지지구조는 종래의 일반적 구성을 대부분 포함하는 바, 캐소드(K)를 감싸도록 구성된 캐소드 홀더(11)와, 이 캐소드 홀더(11)의 외주에 접합되어 비이드 글래스(B)에 매립되는 지지편(12)을 구비한다. 지지편(12)의 중앙부에는 캐소드 홀더(11)의 외주에 접합되는 원호형의 접합부(13)가 형성되고, 양 선단에는 비이드 글래스(B)에 매립되는 매립부(14)가 형성된다. 한편 캐소드 홀더(11) 외주의 소정위치에는 본 고안의 특징에 따라 지지편(12)의 접합부(13)가 삽입되는 삽입홈(11a)이 형성된다.2 and 3, the cathode support structure according to the present invention includes most of the conventional general configuration, the cathode holder 11 configured to surround the cathode K, and the outer circumference of the cathode holder 11 The support piece 12 joined to and embedded in the bead glass B is provided. An arcuate joining portion 13 joined to the outer circumference of the cathode holder 11 is formed at the central portion of the support piece 12, and a buried portion 14 embedded in the bead glass B is formed at both ends. On the other hand, at a predetermined position on the outer circumference of the cathode holder 11, an insertion groove 11a into which the joint 13 of the support piece 12 is inserted is formed according to a feature of the present invention.

이와같은 구조적 특징을 가지는 본 고안에 의한 캐소드 지지구조는 캐소드 홀더(11)에 지지편(12)의 접합부(13)가 삽입되는 삽입홈(11a)이 형성되어 있으므로 지지편(12)을 캐소드 홀더(11)의 소정위치에 간단하고 정확하게 접합할 수 있게된다. 이에따라 캐소드(K)와 G1 전극(G1)간의 간격을 정확히 일치시킬 수 있게되므로 종래와 같은 음극선관의 컷 오프 특성 저하가 방지된다.Cathode support structure according to the present invention having such a structural feature is the cathode holder 11 is formed in the insertion groove (11a) is inserted into the junction portion 13 of the support piece 12, the support piece 12 to the cathode holder It is possible to join simply and accurately to the predetermined position of (11). As a result, the gap between the cathode K and the G1 electrode G1 can be exactly matched, thereby preventing the conventional cutoff characteristic of the cathode ray tube.

이와같이 본 고안에 의하면 캐소드를 소정의 위치에 간단하고 정확히 고정할 수 있다. 따라서 본 고안은 완성된 음극선관의 품위와 신뢰성을 향상시키는 효과가 있다.Thus, according to the present invention, the cathode can be fixed simply and accurately at a predetermined position. Therefore, the present invention has the effect of improving the quality and reliability of the finished cathode ray tube.
