Abstract
본 고안은 음극선관용 전자총의 개선된 컨버전스컵을 개시한다. 종래에는 각 벌브스페이서를 컨버전스컵의 외주에 소정각도 간격으로 접합하였는 바, 소정의 위치에 정확히 접합시키기가 대단히 어려울 뿐 아니라 자칫 오접합될 우려가 매우 높은 문제가 있었다. 본 고안에서는 벌브스페이서에 절곡부를 형성하고, 컨버전스컵에 벌브스페이서의 절곡부가 안착되는 복수의 안착홈을 형성함으로써 컨버전스컵의 소정위치에 각 벌브스페이서를 간단하고 정확하게 접합할 수 있도록 하였다.The present invention discloses an improved convergence cup of an electron gun for cathode ray tubes. Conventionally, since the bulb spacers are bonded to the outer periphery of the convergence cup at predetermined angle intervals, there is a problem that it is very difficult to accurately join the predetermined positions, and there is a high possibility of incorrect bonding. In the present invention, a bent portion is formed in the bulb spacer, and a plurality of seating grooves in which the bent portion of the bulb spacer is seated is formed in the convergence cup so that each bulb spacer can be easily and accurately bonded to a predetermined position of the convergence cup.

본 고안은 음극선관(陰極線管) 제조에 관한 것으로, 더 상세히는 전자빔을 발사하는 전자총(electron gun)의 컨버전스컵(convergence cup)에 관한 것이다.The present invention relates to the manufacture of cathode ray tubes, and more particularly to the convergence cup of an electron gun that emits an electron beam.
음극선관은 전자총으로부터 발사된 전자빔을 스크린(screen)상에 선택적으로 랜딩(landing)시킴으로써 화상을 표시하는 장치이다. 이러한 전자총은 전자를 방출하는 캐소드(cathode)와, 방출된 전자를 빔(beam)의 형태로 집속(集束) 및 가속(加速)시키는 복수의 전극들이 일체로 조립되어 제1도에 도시된 바와 같이 벌브(bulb; B)의 네크(neck; N)내에 장착됨으로써 음극선관을 구성하게 된다. 이때 전자총(A)의 전자빔 발사중심과 네크(N)의 중심이 불일치될 경우 화질이 열화(劣化)되게 되므로 음극선관의 제조시 이들간의 정합(alignment)은 매우 정밀하게 관리되어야 한다. 이를 위해 전자총(A)의 컨버전스컵(1)에 복수(통상3개)의 벌브스페이서(bulb spacer; 2)를 구비하여 네크(N)에 대해 탄성적으로 동심(同心) 지지하는 것이 일반적이다.A cathode ray tube is a device that displays an image by selectively landing an electron beam emitted from an electron gun on a screen. Such an electron gun is composed of a cathode for emitting electrons and a plurality of electrodes for focusing and accelerating the emitted electrons in the form of a beam, as shown in FIG. Mounted in the neck (N) of the bulb (B) to form a cathode ray tube. At this time, if the electron beam firing center of the electron gun A and the center of the neck N are inconsistent, the image quality deteriorates, so that the alignment between them should be managed very precisely during manufacture of the cathode ray tube. To this end, it is common to provide a plurality of (usually three) bulb spacers 2 in the convergence cup 1 of the electron gun A so as to elastically support the neck N concentrically.
제2도에는 이러한 종래 컨버전스컵(1)의 일례를 개략적으로 도시하였다. 이것은 컨버전스컵(1)의 외주에 복수의 벌브스페이서(2)를 각각 소정각도 간격으로 용접(welding) 등에 의해 접합한 구성이다.2 schematically shows an example of such a conventional convergence cup 1. This is a configuration in which a plurality of bulb spacers 2 are joined to the outer periphery of the convergence cup 1 by welding or the like at predetermined angle intervals, respectively.
그런데 전자총(A)을 네크(N)에 대해 동심으로 지지하기 위해서는 각 벌브스페이서(2)가 컨버전스컵(1)의 선단으로부터 동일한 높이와 각도에 접합되어야 하는 바, 종래에는 이를 정확히 일치시키기가 대단히 어려울 뿐 아니라 자칫 오접합(誤接合)될 우려가 매우 높았다. 이에 따라 전자총(A)이 네크(N)에 대해 틸트(tilt)되는 등 음극선관의 제조효율 및 신뢰성을 보장할 수 없는 문제가 있었다.However, in order to support the electron gun A concentrically with respect to the neck N, each bulb spacer 2 should be joined at the same height and angle from the tip of the convergence cup 1. Not only was it difficult, but there was also a high risk of misjunction. Accordingly, there is a problem that the manufacturing efficiency and reliability of the cathode ray tube cannot be guaranteed such that the electron gun A is tilted with respect to the neck N.
본 고안의 목적은 이러한 종래의 문제를 감안하여 각 벌브스페이서를 컨버전스컵의 소정위치에 간단하고 정확하게 접합시킬 수 있는 음극선관용 전자총을 제공하는 것이다.It is an object of the present invention to provide a cathode ray tube electron gun which can be simply and accurately bonded to each bulb spacer at a predetermined position of a convergence cup in view of such a conventional problem.
이와 같은 목적을 달성하기 위해 본 고안은 전자빔을 발사하는 복수의 전극과, 전자빔을 컨버전스 시키는 컨버전스컵과, 이 컨버전스컵에 접합되는 복수의 벌브스페이서 등을 구비하는 음극선관용 전자총에 있어서, 각 벌브스페이서의 소정위치에 절곡부가 형성되고, 컨버전스컵에 각 벌브스페이서의 절곡부가 각각 안착되는 복수의 안착홈이 소정각도 간격으로 형성되어 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a cathode ray tube electron gun including a plurality of electrodes for emitting an electron beam, a convergence cup for converging the electron beam, and a plurality of bulb spacers joined to the convergence cup. The bent portion is formed at a predetermined position of the plurality of seating grooves on which the bent portions of each bulb spacer are respectively seated in the convergence cup, characterized in that formed at predetermined angle intervals.
이에 따라 본 고안은, 각 벌브스페이서를 컨버전스컵에 간단하고 정확하게 접합시킬수 있게 되므로 음극선관의 제조효율 및 신뢰성 향상에 큰 효과를 발휘하게 된다.Accordingly, the present invention, since it is possible to simply and accurately bonded each bulb spacer to the convergence cup has a great effect on improving the production efficiency and reliability of the 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.
제3도 및 제4도에서, 본 고안에 의한 음극선관용 전자총의 컨버전스컵(11)은 본 고안의 특징에 따라 그 상단에 벌브스페이서(12)가 결합되는 복수의 안착홈(11a)이 소정각도 간격으로 각각 인입되어 형성된다. 이 안착홈(11a)은 바람직하기로 그 상단으로부터 각각 동일한 길이를 가진다. 이에 따라 각 벌브스페이서(12)에는 컨버전스컵(11)의 안착홈(11a)에 각각 안착되어 결합될 수 있도록 절곡부(12a)가 형성된다. 이 절곡부(12a)는 벌브스페이서(12)가 컨버전스컵(11)의 외주에 용접등으로 접합될수 있을 정도의 접합부(12b)를 제외한 소정의 위치에 형성되는 것이 바람직하다.3 and 4, the convergence cup 11 of the cathode ray tube electron gun according to the present invention has a plurality of seating grooves 11a to which the bulb spacer 12 is coupled at a predetermined angle according to the features of the present invention. It is formed by drawing in each interval. The seating grooves 11a preferably have the same length from their upper ends, respectively. Accordingly, each bulb spacer 12 is formed with a bent portion (12a) to be seated and coupled to each of the seating groove (11a) of the convergence cup (11). The bent portion 12a is preferably formed at a predetermined position except for the junction portion 12b such that the bulb spacer 12 can be joined to the outer circumference of the convergence cup 11 by welding or the like.
이와 같은 구조적 특징을 가지는 본 고안에 의한 전자총의 컨버전스컵과 벌브스페이서의 접합은 다음과 같다.The junction of the convergence cup of the electron gun and the bulb spacer according to the present invention having such a structural feature is as follows.
먼저 컨버전스컵(11)을 소정의 지그(도시안됨)에 세팅한다. 다음 컨버전스컵(11)의 안착홈(11a)에 벌브스페이서(12)의 절곡부(12a)를 각각 안착시킨다. 그러면 각 벌브스페이서(12)의 접합부(12b)가 컨버전스컵(11)의 외주에 각각 접촉된다. 이와 같은 상태에서 각 벌브스페이서의 접합부(12b)를 컨버전스컵(11)에 용접 등에 의해 순차적으로 접합한다.First, the convergence cup 11 is set to a predetermined jig (not shown). Next, the bent portions 12a of the bulb spacers 12 are respectively seated in the seating grooves 11a of the convergence cup 11. Then, the junction part 12b of each bulb spacer 12 contacts each outer periphery of the convergence cup 11, respectively. In this state, the joining portions 12b of the bulb spacers are sequentially joined to the convergence cup 11 by welding or the like.
이와 같이 본 고안에 의하면, 각 벌브스페이서를 컨버전스컵에 간단하면서도 정확하게 접합시킬 수 있게 되므로 종래와 같이 오접합에 의한 전자총의 틸트 등을 방지할 수 있다. 따라서 본 고안은 음극선관의 제조효율 향상 및 신뢰성 향상에 큰 효과가 있다.Thus, according to the present invention, since each bulb spacer can be easily and accurately bonded to the convergence cup, the tilt of the electron gun due to the misjunction can be prevented as in the prior art. Therefore, the present invention has a great effect on improving the production efficiency and reliability of the cathode ray tube.
