본 고안은 음극선관용 전자총에 관한 것으로서, 특귀 전자총의 전극을 견고하게 고정할수 있는 음극선관용 전자총의 비이드글래스에 관한 것이다.The present invention relates to an electron gun for a cathode ray tube, and relates to a bead glass of an electron gun for a cathode ray tube capable of firmly fixing an electrode of a special electron gun.
종래 전자총의 비이드글래스(B)는 제1도에 도시된 바와같이 형성되어서 전자총(EG)을 구성하는 전극(G)의 매립부(M)가 몰입되는바 구조적인 결합에 의해 매립상태가 볼안정하여 작은 충격에 의해서도 전극(G)의 흔들림이 발생되어 화상의 떨림 또는 화이트 밸린스 등이 야기된다.The bead glass B of the conventional electron gun is formed as shown in FIG. 1 so that the buried portion M of the electrode G constituting the electron gun EG is immersed in the buried glass B. Even when a small impact is stable, shaking of the electrode G occurs, causing image shaking or white balance.
이는 바이드글래스(B)의 일측면이 호형으로된 사각형의 형상을 갖고 있어서 가열될때에 그 몸체가 골고루 가열되지 않으며, 걸과적으로 전극의 매립부(M)의 몰입상태가 블균일 하게된다. 또한 매립부(M) 부위에 조직의 뒤틀림에 의한 응력이 불균일하게 산포되기 때문인 것이다.This is because one side of the bead glass (B) has an arc-shaped quadrangular shape, the body is not evenly heated when heated, and the immersion state of the buried portion M of the electrode is unevenly uniform. In addition, it is because the stress caused by the distortion of the tissue is unevenly distributed in the buried portion (M).
이는 전극의 매립부(M)가 비이드글래스(B)에 매립될때에 두께가 부위 즉, 충분하게 가열 되지 않은 비이드글래스(B)의 중심부가 매립부(M)에 의하여 과다한 외력으로서 압착되기 때문인 것으로서, 경우에 따라서는 크랙이 밭생되는 문제점이 있었다.This is because when the buried portion M of the electrode is buried in the bead glass B, a portion having a thickness, that is, a central portion of the bead glass B that is not sufficiently heated, is compressed by the buried portion M as an excessive external force. As a result, in some cases, there was a problem that the cracks were born.
따라서 본 고안은 전극의 매립강도를 강화하여 매립 불량을 개선할수 있는 음극선관용 전자총의 비이드글래스를 제공함에 그 목적이 있다.Therefore, an object of the present invention is to provide a bead glass of a cathode ray tube electron gun that can improve a buried defect by strengthening the embedding strength of the electrode.
상기 목적을 달성하기 위하여 본 고안은 전자총의 전극 매립부를 몰입파지하여 전극들을 일정간격으로 고정지지하는 비이드글라스에 있어서, 음곽선관 네트에 마주대하는 부위를 만곡되게 호형으로 형성하며, 전극의 매립부가 몰입파지되는 부위에는 일정폭의 요입홈을 길이방향으로 길게 형성하여서, 비이드글래스의 두께가 전체적으로 가능한 일정하게 되도록 하는 점에 그 특징이 있다.In order to achieve the above object, the present invention has a bead glass for immersing and supporting the electrode buried portion of the electron gun to fix and support the electrodes at a predetermined interval. The immersion gripping portion is characterized in that the recessed groove having a predetermined width is formed long in the longitudinal direction, so that the thickness of the bead glass is as constant as possible as a whole.
이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도 및 제3도에 고안에 따른 비이드글래스(Ba)를 채용한 음극선관용 전자총이 도시되어 있는바, 전자총을 구성하는 각 전극들의 매립부(M1) 양측에 매립부(M1)와 비슷한 높이로 넓은 폭을 가진 비이드글래스(Ba)에 몰입고정되는 별도의 전극 지지체(S)을 고착하는 한편, 비이드글래스(Ba)의 내측면에는 길이 방향으로 요입홈(B0)을 형성한다. 또한 비이드글래스의 두께를 일정하게 하기 위하여 상기 내측면에 대응되게 내측면이 만곡된 만큼 외측면을 돌출되게 형성한다. 따라서 제3도에 도시된 바와같이 요입홈(B0)에는 상기 전극(G)의 매립부(M1)가 고착되고 요입홈(B0)이 형성되지 않은 그 양측(U)에는 전극 지지체(5)가 고착된다.2 and 3, the electron gun for the cathode ray tube employing the bead glass (Ba) according to the invention is shown, the buried portion (M 1 ) on both sides of the buried portion (M 1 ) of the electrodes constituting the electron gun While fixing the separate electrode support (S) immersed in the bead glass (Ba) having a wide width to a height similar to the other, while the recessed groove (B 0 ) in the longitudinal direction on the inner surface of the bead glass (Ba) Form. Further, in order to make the thickness of the bead glass constant, the outer surface is formed to protrude as much as the inner surface is curved to correspond to the inner surface. Thus it iphom (B 0) is the electrode substrate buried portions (M 1) is fixed and requires iphom (B 0) the two sides (U) is not formed of the electrode (G) as shown in FIG. 3 ( 5) is stuck.
이와 갈이 구성된 본 고안은 전자총의 비이드글래스(Ba) 두께를 일정하게 형성함으로써 전자총의 전극(G)을 고착하기 위하여 이를 가열하게 되면 비이드글래스(Ba)의 전체가 일정하게 가열된다. 따라서 전극들의 매립부(M1)와 전극지지체(S)가 비이드글래스(Ba)에 매립 될때에 고른 압착력으로서 비이드글래스의 몸체에 파고 들게된다. 따라서 응력의 산포가 고르게 되며 나아가서는 비이드글래스(Ba)의 균열이 억제된다.The present invention is composed of a galvanic glass (Ba) of the electron gun by forming a constant thickness to be fixed to the electrode (G) of the electron gun to heat it, the entire bead glass (Ba) is constantly heated. Therefore, when the buried portion (M 1 ) and the electrode support (S) of the electrodes are embedded in the bead glass (Ba) is to be dug into the body of the bead glass as an even pressing force. Therefore, the stress distribution is even, and further, cracking of the bead glass Ba is suppressed.
이는 비이드글래스(Ba)가 가열될 때에 그 몸체의 표면으로부터 그 중심부까지 전달되는 열량이 일정하여서 그 몸체의 중심부까지도 충분하게 가열되므로 전극(G)의 매립부(M1)가 깊게 매립되어도 응력이 집중 또는 불균일한 산포가 방지되며 나아가서는 비이드글래스의 깨어짐을 방지할 수 있는 것이다. 또한 전극들의 매립부(M1)뿐만 아니라 전극지지체(5)가 비이드글래스(Ba)에 매립되고 비이드글래스의 폭이 종래보다 넓게 형성되어 있기 때문에 각 전극들의 매립강도를 높일 수 있다.This is because even when the bead glass Ba is heated, the amount of heat transferred from the surface of the body to the center of the body is constant, so that even the center of the body is sufficiently heated, even when the buried portion M 1 of the electrode G is embedded deeply. This concentration or non-uniform dispersion is prevented and further, the bead glass can be prevented from breaking. In addition, since the electrode support 5, as well as the buried portion M 1 of the electrodes, is embedded in the bead glass Ba and the width of the bead glass is wider than in the related art, the embedding strength of each electrode may be increased.
이와 같은 본 고안 음극선관용 전자총의 비이드글래스는 설계가 단순하고 매립강도 중심적을 설계되어 있으므로 전극의 융착시 매립불량 및 크랙을 방지할수 있기 때문에 전자총의 신뢰성을 제공하며 생산성을 크게 향상시킬수 있는 것이다.Since the bead glass of the present invention cathode ray tube electron gun has a simple design and is designed with a center of embedding strength, it is possible to prevent poor filling and cracks during welding of the electrode, thereby providing reliability of the electron gun and greatly improving productivity.
