Abstract

본 고안은 전극을 비이드 글래스에 고정하여 전자총을 구성하게 하는 개선된 매립편을 개시한다.The present invention discloses an improved buried piece that secures an electrode to a bead glass to form an electron gun.

종래에는 매립편의 지지강도가 약하여 전극이 틀어지거나 외부 충격등에 의해 유동 또는 이탈됨으로써 전자총 특성이 안정되지 못하는 문제가 있었다.Conventionally, there is a problem that the electron gun characteristics are not stabilized because the support strength of the buried piece is weak and the electrode is distorted or flows or leaves due to an external impact.

본 고안에서는 매립편의 텅에 인입홈을 형성하여 비이드 글래스와의 사이에 쐐기 역할을 하도록 함으로써 이러한 문제를 해결하였다.The present invention solved this problem by forming an inlet groove in the tongue of the buried piece to serve as a wedge between the bead glass.

본 고안은 브라운관에 관한 것으로, 특히 전자총 어셈블리를 구성하는 전극의 매립편(埋立片)에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly, to a buried piece of an electrode constituting an electron gun assembly.

브라운관은 전자총 어셈블리에서 발사된 전자빔을 편향수단에 의해 형광면의 각 위치에 순차적으로 주사시킴으로써 화상을 표시하는 장치이다.The CRT is an apparatus for displaying an image by sequentially scanning the electron beam emitted from the electron gun assembly to each position of the fluorescent surface by the deflecting means.

전자빔은 전자총 어셈블리의 캐소드(cathode)에서 발생된 열전자를 복수의 전극에 의해 집속(集束) 및 가속(加速)함으로써 형성된다.The electron beam is formed by focusing and accelerating hot electrons generated at the cathode of the electron gun assembly by a plurality of electrodes.

이에 따라 전자총 어셈블리는 제1도에 도시된 바와같이 다수의 전극(G)들이 동축으로 결합되어 이루어진다. 전극(G)들의 결합에는 일반적으로 비이드 글래스(bead glass : B)라는 일종의 유리막대가 사용되는데, 제2도에 도시된 바와같이 각 전극(G)의 외주에 부착되거나 형성된 매립편(E)에 비이드 글래스(B)를 열연화 상태로 압입시켜 경화시키면 전극(G)이 매립편(E)이 비이드 글래스(B)에 매립되어 복수의 전극(G)이 한 전자총 어셈블리로 결합된다.Accordingly, the electron gun assembly is formed by coupling a plurality of electrodes G coaxially as shown in FIG. In order to bond the electrodes G, a kind of glass rod called bead glass B is generally used. As shown in FIG. 2, the buried glass E attached or formed on the outer circumference of each electrode G is used. When the bead glass B is pressed in the thermosoftening state and cured, the electrode G is embedded with the buried piece E in the bead glass B, and the plurality of electrodes G are combined into one electron gun assembly.

매립편(E)은 제2도에 도시된 바와같이 하나 또는 복수의 텅(tungue : T)을 가지고 있는데, 도시된 구성에서는 두 텅(T)이 서로 내측을 향해 경사진 상태로 구성되어 있다.The buried piece E has one or a plurality of tongues T, as shown in FIG. 2, but in the illustrated configuration, the two tongues T are inclined inward to each other.

이러한 경사는 매립편(T)의 매립강도를 높이기 위해 형성된 것인바, 이 경사가 지나치면 비이드 글래스(B)에 캐비티(cavity)가 형성되는등 압입이 잘 이루어지지 않는 문제가 유발된다.This inclination is formed to increase the embedding strength of the buried piece (T), if the inclination is excessive, such as a cavity (cavity) is formed in the bead glass (B) causes a problem that the indentation is not made well.

이에 따라 종래의 매립편(E)은 그 매립강도가 약해 전극(G)들이 서로 정합되지 못하고 틀어지거나, 약간의 외부 충격에도 쉽게 유동하여 화이트 밸런스(white balance)등 특성이 변화되는 문제가 있었다.Accordingly, the conventional buried piece E has a problem in that its embedding strength is weak, so that the electrodes G are not matched with each other, are distorted, or are easily flowed even by a slight external impact, such that white balance and other characteristics are changed.

이와같은 종래의 문제점을 감안하여 본 고안의 목적은 비이드 글래스에는 매립강도를 향상시켜 안정된 브라운관 특성의 유지가 가능한 매립편을 제공하는 것이다.In view of such a conventional problem, an object of the present invention is to provide a buried piece of bead glass capable of maintaining stable CRT characteristics by improving embedding strength.

상술한 목적을 달성하기 위해 본 발명에 의한 전자총 전극의 매립편은 텅의 측부에 내측으로 인입되는 인입홈(recess)이 형성되는 것을 특징으로 한다.In order to achieve the above object, the buried piece of the electron gun electrode according to the present invention is characterized in that a recess is introduced into the side of the tongue.

이러한 구성에 의하면 매립편의 텅이 비이드 글래스에 진입하면 변화상태의 비이드 글래스의 일부가 이 인입홈에 밀려들어 경화됨으로써 매립편의 이탈이나 유동을 방지하는 쐐기(wedge) 작용을 하게 된다.According to such a configuration, when the tongue of the buried piece enters the bead glass, a part of the bead glass in the changed state is pushed into the inlet groove and hardened, thereby acting as a wedge to prevent the separation or separation of the buried piece.

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.

제3도에서, 전극(G)에 부착 또는 일체로 형성되어 전극(G)을 비이드 글래스(B)에 고정시키는 본 고안 매립편(E)은 비이드 글래스(B)에 매립될 복수의 텅(T)을 가지는데, 이 텅(T)의 측부에는 내측으로 인입되는 인입홈(R)이 형성된다.In FIG. 3, the buried piece E of the present invention, which is attached to or integrally formed with the electrode G and fixes the electrode G to the bead glass B, has a plurality of tongues to be embedded in the bead glass B. FIG. Although it has (T), in the side of this tongue (T) is formed an inlet groove (R) leading inward.

이 인입홈(R)은 매립편(E)의 텅(T)이 열연화상태의 비이드 글래스(B)에 진입하면 비이드 글래스(B)의 일부가 이 인입홈(R)내에 유입되어 경화됨으로써, 쐐기와 같이 매립편(E)을 비이드 글래스(B)내에 견고히 고정해주게 된다.When the tongue T of the buried piece E enters the bead glass B in the thermal softening state, a part of the bead glass B flows into the inlet groove R and hardens. As a result, the buried piece E is firmly fixed in the bead glass B like a wedge.

이에따라 외부 충격등에 의해 매립편(E)이 비이드 글래스(B)에서 유동되거나 이탈되지 않게 되어 전극(G)들의 정합상태가 유지되고 특성이 변화되는 문제가 근본적으로 방지된다.Accordingly, the buried piece E does not flow or escape from the bead glass B due to an external impact or the like, thereby preventing the problem of maintaining the matched state of the electrodes G and changing the characteristics.

이에 따라 본 고안은 특히 음극선관용 전자총 어셈블리에 우수하고 안정된 특성을 제공하는 효과가 있다.Accordingly, the present invention has an effect of providing excellent and stable characteristics, particularly in the electron gun assembly for cathode ray tubes.
