32 : 돌출부 R, G, B : 전자빔 통과공32: projection R, G, B: electron beam through hole
본 고안은 칼라 음극선관용 전자총에 관한 것으로, 더 상세하게는 열팽창에 의해 발생되는 열적 콘버어전스 드리프트(thermal convergence drift) 현상과 전자빔 상호간의 간섭을 방지할 수 있는 전자총의 전극에 관한 것이다.The present invention relates to an electron gun for a color cathode ray tube, and more particularly, to an electrode of an electron gun that can prevent thermal convergence drift caused by thermal expansion and interference between electron beams.
통상적으로 칼라 음극선관용 전자총은 음극선관의 네트부에 장착되어 형광막을 여기시키는 전자빔의 방출원으로써 열전자 방출원인 캐소오드와 보조 및 주렌즈를 이루는 복수개의 판상의 전극 및 팀전극을 구비하여 구성된다.Typically, an electron gun for a color cathode ray tube is provided with a plurality of plate-shaped electrodes and team electrodes constituting a cathode and a secondary and main lens as cathodes as hot electron emission sources as an emission source of an electron beam mounted on a net portion of a cathode ray tube to excite a fluorescent film.
상기와 같이 구성된 칼라 음극선관용 전자총은 각 전극에 소정의 전위가 인가됨에 따라 상기 캐소오드로부터 방출된 전자빔이 각 전극 사이에 형성되는 전자렌즈에 의해 집속 및 가속된 후 형광막의 주사위치에 따라 선택적으로 편향되어 형광막에 탠딩되게 된다.The electron gun for the color cathode ray tube configured as described above is selectively subjected to the electron beam emitted from the cathode by focusing and accelerating by an electron lens formed between each electrode as a predetermined potential is applied to each electrode. It is deflected and stands on the fluorescent film.
이러한 칼라 음극선관용 전자총의 판상 전극부재는 특히 캐소오드와 인접되게 설치되어, 전자빔을 제어하는 전국부재는 그 구조가 상대적으로 약하므로 제1도에 도시된 바와 같이 전극(12)에 형성된 전자빔 통과공(12H)과 대응되는 부위에 캐소오드(11)가 삽입되는 보강판부재(15)를 설치하고 있다. 상기와 같이 판상의 전극부재(12)에 보강판부재(15)를 설치하는 것은 판상전극부재(12)의 구조적 강도를 향상시킴과 아울러 각 캐소오드(11)로부터 방출되는 전자빔 상호간의 간섭을 방지하게 된다.The plate-shaped electrode member of the electron gun for the color cathode ray tube is particularly installed adjacent to the cathode, so that the nationwide member for controlling the electron beam is relatively weak in structure so that the electron beam passing hole formed in the electrode 12 is shown in FIG. The reinforcement board member 15 into which the cathode 11 is inserted is provided in the part corresponding to 12H. Installing the reinforcing plate member 15 on the plate-shaped electrode member 12 as described above improves the structural strength of the plate-shaped electrode member 12 and prevents interference between the electron beams emitted from the respective cathodes 11. Done.
그리고 상기 판상의 전극부재를 보강하기 위한 다른 실시예는 제2도에 도시된 바와같이 판상의 전극부재(21)에 전자빔 통과공(21H)를 감싸며 캐소오드(11)가 삽입되는 림(22a)이 형성된 보강판부재(22)를 설치하여 전자빔 상호간의 간섭을 방지하고 있다.Another embodiment for reinforcing the plate-shaped electrode member is shown in FIG. 2 is a rim 22a in which the cathode 11 is inserted while enclosing the electron beam passing hole 21H in the plate-shaped electrode member 21. The formed reinforcing plate member 22 is provided to prevent interference between the electron beams.
그러나 상기와 같이 판상의 전극부재(12)(21)에 보강판부재(15)(23)를 설치하여 전극의 구조적 강도를 향상시키고 전자빔 상호간의 간섭을 방지하고 있으나 이는 전극부재의 제작에 따른 많은 작업공수가 소요되는 문제점이 내재되어 있으며, 특히 열전자에 의해 전극부재의 열팽창시 열팽창량을 충분히 흡수할 수 없는 문제점이 내재되어 있다. 또한 상기 캐소오드와 인접되게 설치된 판상 전극부재(12)(21)에 보강판부재(15)(22)를 설치하는 것은 전국의 열적용량이 상대적으로 커지게되고 나아가서는 열적안정화 시간이 길어지게 되어 이를 채용한 음극선관의 초기 안정화시간이 길어지게 되는 문제점이 있다.However, as described above, the reinforcing plate members 15 and 23 are installed on the plate-shaped electrode members 12 and 21 to improve the structural strength of the electrodes and to prevent the interference between the electron beams. There is a problem in that labor is required, and in particular, there is a problem in that thermal expansion of the electrode member cannot be sufficiently absorbed by the thermal electrons. In addition, the installation of the reinforcing plate members 15 and 22 on the plate-shaped electrode members 12 and 21 provided adjacent to the cathode increases the heat capacity of the whole country and further increases the thermal stabilization time. There is a problem that the initial stabilization time of the cathode ray tube employing this becomes long.
본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로, 열팽창에 따른 열변형량을 줄일 수 있으며, 외부의 충격에 대해 완충효과를 가지며 구조가 간단한 칼라 음극선관용 전자총의 전극을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, it is possible to reduce the amount of thermal deformation due to thermal expansion, has a buffer effect against external impact, and has an object of providing an electrode of the electron gun for a color cathode ray tube simple structure.
상기 목적을 달성하기 위하여 본 고안은, 상호 소정간격 이격된 세 개의 전자빔 통과공이 형성된 판상의 본체를 구비하여 된 칼라 음극선광용 전자총의 전극에 있어서, 상기 각 전자빔 통과공의 주위에 비딩가공되어 돌출된 돌출부를 구비하여 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention, in the electrode of a color cathode ray gun electron gun provided with a plate-shaped body formed with three electron beam passing holes spaced at a predetermined interval from each other, the beading process is protruded around each electron beam through hole It is characterized by having a protrusion.
본 고안에 있어서, 상기 비딩가공된 돌출부는 전자빔 방출원인 캐소오드를 감살 수 있도록 된 것을 그 특징으로 한다.In the present invention, the beaded protrusion is characterized in that the cathode can be reduced to the electron beam emission source.
이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
칼라 음극선관용 전자총은 열전자를 방출하는 캐소오드와 전자빔을 집속 및 가속하는 복수개의 판상의 전극 및 림전극을 구비하여 구성되는데, 제3도에는 본 고안에 따른 판상 전극(30)의 일예를 나타내 보였다.The electron gun for a color cathode ray tube includes a cathode and a plurality of plate-shaped electrodes and rim electrodes for focusing and accelerating electron beams. FIG. 3 shows an example of a plate-shaped electrode 30 according to the present invention. .
이것은 판상의 본체(31)에 소정의 간격으로 세 개의 전자빔 통과공(R)(G)(B)이 인라인 상으로 형성되고 각 전자빔 통과공(R)(G)(B)의 주위에는 비딩가공되어 일측방향으로 돌출된 돌출부(31)가 형성된다. 이때에 상기 돌출부(32)은 전자빔 통과공(R)(G)(B)과 인접되게 설치된 캐소오드를 감쌀 수 있도록 함이 바람직하다.This is formed by three electron beam through holes (R) (G) (B) formed in an in-line shape at predetermined intervals in the plate-shaped main body 31 and beading around each electron beam through holes (R) (G) (B). As a result, a protrusion 31 protruding in one direction is formed. At this time, the protrusion 32 is preferably so as to surround the cathode is installed adjacent to the electron beam through hole (R) (G) (B).
이와같이 구성된 본 고안에 따른 칼라 음극선관용 전자총의 작용을 설명하면 다음과 같다.Referring to the operation of the electron gun for color cathode ray tube according to the present invention configured as described above are as follows.
본 고안에 따른 칼라 음극선관용 전자총의 전극부재 즉, 캐소오드와 인접되게 설치된 전극(30)은 열전자 방출원인 캐소오드의 히이터로부터 발생된 열에 의해 가열됨에 따라 열팽창되게 되는데, 상기 전극(30)은 각 전자빔 통과공(R)(G)(B)의 가장자리에 비딩된 돌출부(32)가 형성되어 있으므로 열팽창량을 흡수할 수 있으며 외부로부터 가하여지는 충격을 완충시킬 수 있다.The electrode member of the electron gun for the color cathode ray tube according to the present invention, that is, the electrode 30 installed adjacent to the cathode is thermally expanded as it is heated by the heat generated from the heater of the cathode, which is the source of the hot electron emission, and the electrode 30 is each Since the projecting portion 32 beaded at the edges of the electron beam passing holes R, G, and B is formed, the amount of thermal expansion can be absorbed and the shock applied from the outside can be buffered.
또한 상기 전자총의 전극(30)의 돌출부(32)에는 캐소오드를 감싸고 있으므로 캐소오드로부터 방출된 전자빔의 간섭을 방지할 수 있어 캐소오드로부터 방출되는 전자빔의 컷오프 특성을 향상시킬 수 있으며, 특히 상기 전극(30)은 종래의 전극에 비하여 열포화용량이 적어 열적 포화상태가 짧은 시간내에 이루어지게 되므로 이를 채용한 음극선관의 초기안정화시간을 줄일 수 있다.In addition, since the projection 32 of the electrode 30 of the electron gun surrounds the cathode, the interference of the electron beam emitted from the cathode can be prevented, so that the cutoff characteristic of the electron beam emitted from the cathode can be improved. In particular, the electrode 30 has less thermal saturation capacity than a conventional electrode, and thus, the thermal saturation state is achieved within a short time, thereby reducing the initial stabilization time of the cathode ray tube employing the same.
이상에서 설명한 바와 같이 본 고안 칼라 음극선관용 전자총의 전극은 전자빔 통과공의 둘레에 캐소오드를 감싸는 돌출부를 비딩가공하고 형성함으로써 종래의 전극에 비하여 그 구조적 강도를 향상시킬 수 있고 제작에 따른 작업공수를 대폭 줄일 수 있는 이점을 가진다. 또한 전극의 열팽창에 따른 전극의 변형 특히 전자빔 통과공의 이동을 방지하여 열적 콘버어전스 드리프트 현상을 방지할 수 있는 이점을 가진다.As described above, the electrode of the present invention color cathode ray tube electron gun can be formed by beading and forming a protrusion surrounding the cathode around the electron beam through-hole, thereby improving its structural strength compared to the conventional electrode, and the labor of manufacturing It has the advantage of greatly reducing. In addition, the deformation of the electrode due to thermal expansion of the electrode, in particular, the movement of the electron beam through-holes is prevented to have an advantage of preventing the thermal convergence drift phenomenon.
