본 고안은 음극선관용 전자총의 실드컵과 최종가속전극간의 결합구조를 개선한 것으로서, 특히 실드컵과 최종가속전극이 스폿트 용접되는 작업에서 실드켭과 가속전극간의 상대위치가 변동되는 것을 극소화할 수 있도록 구성된 것에 관한 것이다.The present invention improves the coupling structure between the shield cup and the final accelerating electrode of the electron gun for cathode ray tube, and in particular, it is possible to minimize the variation of the relative position between the shield on and the acceleration electrode during the spot welding of the shield cup and the final accelerating electrode. It is about what is configured.

전자총의 실드컵은 최종가속전극의 선단부에 결합되는 것으로서, 전자총의 부품중 스크린면에 가장 근접되며, 전자빔의 편향점 가까이에 위치된다. 이러한 실드컵은 제3도에 도시된 바와 같이 최종가속전극(20)과 용접이 되는바, 이때에 상기 실드컵(10)의 바닥면(11)에 일직선상으로 형성된 3개의 전자빔통과공(12)(12)(12)들의 중심축과 가속전극(20)의 전자빔통과공(22)(22)(22)의 중심축 모두는 동일 평면상에 위치되어야만 한다. 그러나 이들 실드컵과 가속전극은 전자빔통과공이 형성된 이후에 결합되기 때문에 용접되기 전에 서로의 위치를 잡아줄 수 있는 수단이 마련되어야 한다.The shield cup of the electron gun is coupled to the tip of the final accelerating electrode, which is closest to the screen surface of the components of the electron gun, and is located near the deflection point of the electron beam. The shield cup is welded to the final accelerating electrode 20 as shown in FIG. 3. At this time, three electron beam through holes 12 formed in a straight line on the bottom surface 11 of the shield cup 10. Both the central axis of the 12 and 12 and the central axis of the electron beam passing holes 22 and 22 and 22 of the acceleration electrode 20 should be located on the same plane. However, since the shield cup and the accelerating electrode are coupled after the electron beam through hole is formed, a means for positioning each other before welding is required.

이를 위하여 종래에는 상기 가속전극(20)과 실드컵(10)의 서로 대응되는 부위에 각각 반구형의 안내돌출부(P')와, 이에 대응되는 안내홈(H')을 마련하였던바, 보통4쌍정도를 90°간격으로 형성하였다. 그러나 상기한 안내돌출부(P')는 도시된 바와 같이 반구형의 돌출편을 갖도록 되어 있기 때문에 안내 돌출부(P')가 안내홈(W')에 끼워졌을 때에, 안내홈(H')의 가장자리가, 안내돌출부(P')의 저부 가장자리와 정확하게 마주 대하지 못하고, 완만하게 곡면을 이룬 안내돌출부(P')의 표면위에 위치될 우려가 있는 것이다.To this end, in the related art, hemispherical guide protrusions P ′ and corresponding guide grooves H ′ are respectively provided at portions corresponding to each other of the acceleration electrode 20 and the shield cup 10. Degrees were formed at 90 ° intervals. However, since the guide protrusion P 'has a hemispherical protrusion as shown in the drawing, when the guide protrusion P' is fitted into the guide groove W ', the edge of the guide groove H' It is not possible to exactly face the bottom edge of the guide protrusion P ', and may be located on the surface of the guide protrusion P' that is gently curved.

즉 상기한 안내돌출부(P')의 형상이 반구형으로 되어 있기때문에 이에 대응되는 안내홈(H')과 약간 엇비슷하게 결합된 우려가 있는바, 이와 같이 되면 상기한 바와 같은 필수적 요건, 즉 실드컵의 전자통과공의 중심축들과 가속전극의 전자빔통과공의 중심축이 동일 평면에 위치되어야만 하는 전자총의 기본적 조건을 벗어나서, 상기한 중심축들은 하나의 왜곡된 평면상에 위치된다. 결과적으로 전자총으로 부터의 전자빔이 소망하지 않는 궤도를 통하여 스크린면에 충돌되기 때문에 칼라 음극선관의 색순도가 불량해지거나 해상도가 저하되는 등의 문제점이 발생된다.That is, since the shape of the guide protrusion P 'is hemispherical, there is a possibility that the guide groove H' is slightly similar to the guide groove H 'corresponding thereto. The central axes of the electron passing holes of and the electron beam passing holes of the accelerating electrode deviate from the basic conditions of the electron gun, which must be located in the same plane, so that the central axes are located on one distorted plane. As a result, since the electron beam from the electron gun impinges on the screen surface through an undesired orbit, problems such as poor color purity of the color cathode ray tube and reduced resolution occur.

따라서 본고안은 실드컵과 최종가속전극간의 편위에 따라 칼라음극선관의 화질저하를 최대한으로 억제할 수 있는 음극선관용 전자총의 실드컵과 최종가속전극과의 결합구조를 제공함에 그 목적이 있다.Therefore, the purpose of this paper is to provide a coupling structure of the shield cup and the final acceleration electrode of the electron gun for cathode ray tube which can suppress the deterioration of image quality of the color cathode ray tube to the maximum according to the deviation between the shield cup and the final acceleration electrode.

상기의 목적을 달성하기 위하여 본 고안은 인라인형 전자총의 종단에 위치되는 최종 가속전극과 실드컵이 서로용접되기 전에 이들의 위치가 정밀하게 유지되도록 하기위하여, 상기 가속전극과 실드컵에 각각 복수쌍의 안내돌출부와 안내홈을 적정각도 간격으로 서로 대응되게 마련하되, 상기 안내돌출부를 반구형이 아닌 원통상으로 형성하여서 상기 안내돌출부와 안내홈 간의 미끄럼에 의한 편위가 발생되지 않도록 한 점에 특징이 있다.In order to achieve the above object, the present invention has a plurality of pairs of the acceleration electrode and the shield cup, respectively, so that their positions are precisely maintained before the final acceleration electrode and the shield cup are welded to each other. The guide protrusions and the guide grooves are provided to correspond to each other at appropriate angle intervals, but the guide protrusions are formed in a cylindrical shape instead of a hemispherical shape so that the deviation between the guide protrusions and the guide grooves does not occur. .

고안을 더욱 상세히 설명한다.Describe the design in more detail.

제1도에 인라인형의 전자빔통과공(12)(12)(12),(22)(22)(22)를 가진 실드컵(10)과 최종가속전극(20)이 각각 도시되어 있는바, 실드컵(10)의 바닥면(11)의 가장자리에 90°간격으로 그 단부가 폐쇄된 원통상의 안내돌출부(P)와 안내홈(H)이 번갈아 가면서 형성되어 있고, 최종가속전극(20)의 상하플랜지(21)의 양측단 가까이에는 상기 실드컵(10)의 안내돌출부(P)와 안내홈(H)과 대응되는 위치에 안내홈(H)과 안내돌출부(P)가 형성된다.In FIG. 1, the shield cup 10 and the final acceleration electrode 20 having the in-line electron beam through holes 12, 12, 12, 22, 22 and 22 are respectively shown. Cylindrical guide protrusions P and guide grooves H whose ends are closed at 90 ° intervals at the edges of the bottom surface 11 of the shield cup 10 are alternately formed, and the final accelerating electrode 20 Guide grooves H and guide protrusions P are formed at positions corresponding to the guide protrusions P and the guide grooves H of the shield cup 10 near both side ends of the upper and lower flanges 21.

이와 같이 구성된 실드컵(10)과 가속전극(20)의 결합상태를 살펴보면, 제2도에 도시된 바와 같이 서로 대응되게 형성된 안내돌출부(P)와 안내홈(H)에 의해서 가속전극(20)과 실드컵(10)간의 편위가 발생되지 않는다. 즉 안내홈(H)에 끼워진 안내돌출부(P)가 원통형으로 되어있기 때문에 종래의 반구형의 안내돌출부가 채용되었을때와 같이 이들이 엇비슷하게 편위되는 일이 없다. 따라서 가속전극(20)과 실드컵(10)간의 결합상태가 정밀하게 된다.Looking at the coupling state of the shield cup 10 and the acceleration electrode 20 configured as described above, the acceleration electrode 20 by the guide protrusion (P) and the guide groove (H) formed to correspond to each other as shown in FIG. And the deviation between the shield cup 10 does not occur. That is, since the guide protrusions P fitted into the guide grooves H are cylindrical, they are not biased similarly as in the case of employing the conventional hemispherical guide protrusions. Therefore, the coupling state between the acceleration electrode 20 and the shield cup 10 is precise.

이와같이 본 고안은 가속전극과 실드컵간의 정상결합위치가 정밀하게 셋팅되도록 하기 때문에 전자총의 구조적 정밀도를 향상시킨다. 특히 실드컵과 전극의 치합상태가 정상위치에서 안정화되기 때문에 고정위치를 교정할 필요가 없게 되고 따라서 용접작업이 매우 간편하고 신속하게 된다.As such, the present invention improves the structural precision of the electron gun because the normal coupling position between the acceleration electrode and the shield cup is set precisely. In particular, since the mating state of the shield cup and the electrode is stabilized at the normal position, it is not necessary to correct the fixed position, and thus the welding operation is very simple and quick.
