본 고안은 브라운관의 전자총에 있어서 전자총을 브라운관 네크부중심에 정확히 설치유지시키기 위한 전자총의 콘버전스컵 외주면에 부착설치되는 벌브스페이서의 탄력보상구조에 관한 것이다.The present invention relates to the elastic compensation structure of the bulb spacer which is attached to the outer circumferential surface of the convergence cup of the electron gun in order to maintain the electron gun in the center of the neck tube neck in the electron gun of the CRT.
제1도는 본 고안과 관련한 한 전형적인 전자총(1)의 설치상태를 예시한 것인데, 이 전자총(1)의 콘버전스컵(2) 외주면에는 전자총(1)을 해당 브라운관 네크부(4)의 중심에 위치시켜 지지함과 동시에 관내면의 도전막(5)과 접하여 전자총(1)상의 관련부품들에 양전압을 인가토록 하여주는 복수의(예컨대 3개의 동일한)벌브스페이서(3a)(3b)(3c)들이 부착설치된다.FIG. 1 illustrates the installation state of a typical electron gun 1 related to the present invention. The electron gun 1 is placed on the outer circumferential surface of the convergence cup 2 of the electron gun 1 at the center of the corresponding tube tube neck 4. A plurality of (e.g., three identical) bulb spacers 3a, 3b, and 3c which are positioned and supported and allow a positive voltage to be applied to related parts on the electron gun 1 in contact with the conductive film 5 on the inner surface of the tube. ) Are attached and installed.
이러한 벌브스페이서들은 도시된 예와 같이 복수개의 동일한 벌브스페이서 (3a)(3b)(3c)들을 콘버전스컵(2)의 외주면에 등간격 방사상으로 부착하여 설치되는 것이 보통이나 브라운관의 관종에 따라서는 이러한 벌브스페이서 (3a)(3b)(3c)들 이외에도, 브라운관에 대한 초기전압 인가시 관내의 잔존 공기분자들과 결합함으로써, 관내 진공도를 높여주는 역할을 하는 게터(GETTER)를 설치지지하기 위한 게터포스터(6)가 전자총(1)의 콘버전스컵(2) 일측에 함께 부착설치되는 경우가 있으며, 이 경우는 상기 게터서포터(6)가 지니는 자체 탄발력으로 인해 게터서포터(6)가 설치된 반대쪽으로 작용하는 부가적인 탄력을 보상해 주는 것이 필요하게 된다.Such bulb spacers are usually installed by attaching a plurality of identical bulb spacers 3a, 3b, 3c radially to the outer circumferential surface of the convergence cup 2 as shown in the example. In addition to these bulb spacers 3a, 3b, and 3c, a getter for installing and supporting a getter which serves to increase the vacuum in the tube by combining with residual air molecules in the tube when an initial voltage is applied to the CRT. The poster 6 may be attached to one side of the convergence cup 2 of the electron gun 1, in this case, the opposite side where the getter supporter 6 is installed due to the self-elasticity of the getter supporter 6. It is necessary to compensate for the additional elasticity acting.
이러한 게터서포터(6)의 설치로 인한 벌스스페이서 (3a)(3b)(3c)들간의 탄력중심의 편위를 보상하기 위해, 종래에는 제3도에서 보는 바와 같이 게터서포터(6) 양측의 벌스스페이서 (3b)(3c)들을, 나머지 벌브스페이서(3a) 및 상기 게터서포터(6)와 함께 힘의 균형을 이룰 수 있는 위치로 소정각도(a)씩 이동시킨 위치에 용접부착하였는데, 이는 벌브스페이서(3a)(3b)(3c)들의 부착위치 상호간에 각도조정이 매우 어렵고, 오차가 발생하기 쉽기 때문에 관련 전자총의 설계, 제작을 더욱 복잡하게 만들 뿐만 아니라 높은 불량발생률을 야기하는 요인이 되어 있다.In order to compensate for the deflection of the center of elasticity between the bulk spacers 3a, 3b and 3c due to the installation of the getter supporter 6, conventionally, as shown in FIG. 3, the bulk spacers on both sides of the getter supporter 6 are shown. (3b) and (3c) were welded to the position where the remaining bulb spacer 3a and the getter supporter 6 were moved by a predetermined angle (a) to a position where the force can be balanced. Since the angle adjustment between the mounting positions of 3a) (3b) and 3c is very difficult and error is likely to occur, it is not only to complicate the design and manufacture of the related electron gun but also to cause a high failure rate.
본 고안은 이러한 종래의 문제점을 해소하기 위해 안출된 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, it will be described in detail based on the accompanying drawings as follows.
즉, 본 고안은 제2도에 도시된 바와 같이 콘버젼스컵(2) 외주면에 복수의, 예컨대 3개의 동일한 벌브스페이서(3a)(3b)(3c)들과 하나의 게터서포터(6)를 부착한 전자총을 브라운관 네크부(4)내에 설치토록 된 것에 있어서, 상기 벌브스페이서(3a)(3b)(3c)들을 콘버젼스컵(2) 외주면에 등간격으로 부착설치하되, 게퍼서포터(6) 상호간의 힘의 균형이 이루어지게하는 내향돌출면(7)을 형성하여서 된 것이다.That is, the present invention attaches a plurality of, for example, three identical bulb spacers 3a, 3b, 3c and one getter supporter 6 to the outer circumferential surface of the convergence cup 2 as shown in FIG. In the case where one electron gun is installed in the CRT neck portion 4, the bulb spacers 3a, 3b and 3c are attached to the outer circumferential surface of the convergence cup 2 at equal intervals. It is by forming an inwardly projecting surface (7) to balance the power of.
이와 같이 된 본 고안은 상술한 바와 같이 브라운관 네크부(4)내면 일측에 형성된 내향 돌출면(7)에 의하여 그에 접하는 벌브스페이서(3a)의 탄력을 증대시켜 게터서포터(6)에 의한 부가의 탄력을 보상할 수 있도록 된 구조에 의해 상기 벌브스페이서(3a)(3b)(3c)들을 게터서포터(6)의 부실과 무관한 등간격으로 콘버전스컵(2) 외주면에 부착설치할 수 있기 때문에 이러한 종류의 전자총의 설계제작을 간편용이하게 할 수 있을 뿐만 아니라 불량발생율을 크게 줄일 수 있는 효과를 제공하게 되는 것이다.The present invention as described above increases the elasticity of the bulb spacer (3a) in contact with the inwardly projecting surface (7) formed on one inner surface of the CRT neck portion (4) as described above, the additional elasticity by the getter supporter (6) This type of bulb spacers 3a, 3b, and 3c can be attached to the outer circumferential surface of the convergence cup 2 at equal intervals irrelevant to the failure of the getter supporter 6 by a structure capable of compensating for Not only can the design and manufacture of the electron gun be simplified, but also the effect of greatly reducing the incidence of defects is provided.
