본 고안은 음극선관용 전극 구조체에 관한 것이다.The present invention relates to an electrode structure for a cathode ray tube.

음극선관용 전극 구조체는 방열형과 직열형이 있으며, 직열형은 속동성을 갖는 반면에 수명이 짧은 결점이 있고, 방열형은 스타트 시간이 긴 대신 장시간 사용에도 균일한 특성을 나타낸다.Cathode ray tube electrode structure has a heat dissipation type and a direct heat type, while the direct heat type has a fastness while having a short lifespan, and the heat dissipation type shows uniform characteristics even for long time use instead of a long start time.

방열형 전극 구조체에서 속동성을 기대할 수 없는 이유는 전자방상 물질이 피착된 금슥재 캠이 슬리브 내애 배치되는 히이터에 의해 가열되는 관계로 전자방사 물질의 확산 속도가 느리다는 구조적인 결합에 기인한다.The reason why the fastness cannot be expected in the heat dissipating electrode structure is due to the structural coupling that the diffusion rate of the electrospinning material is slow due to the heating of the metal cam deposited with the electrospinning material by the heater disposed in the sleeve.

종래부터 방열형 전극구조체의 속동능력을 향상시키기 위하여 히이터의 열 손실을 방지하려는 노력이 계속되고 있으나, 제l도의 도시와 같이 히이터(H)가 수용되는 슬리이브(S)는 그 하부가 열려져 있기 때문에, 이를 통해 누설되는 열 손실이 전체의 20%정도를 점유하고 있는 실정이다.Conventionally, efforts have been made to prevent heat loss of the heater in order to improve the speed capability of the heat dissipating electrode structure, but as shown in FIG. 1, since the lower portion of the sleeve S in which the heater H is accommodated is opened. Therefore, the heat loss leaked through this occupies about 20% of the total.

본고안의 목적은 슬리이브의 하측 개구를 통해 누설되는 열량을 방지함으로씨 금속캡의 가열 시간을 단축하여야 함에 있다.The purpose of this paper is to shorten the heating time of the seed metal cap by preventing the amount of heat leaking through the lower opening of the sleeve.

이에 따라 본 고안은 히이터를 지지하는 단자에 열 차폐판을 일체로 형성하여 홀더의 하측 개구를 차단할수 있도록 구성함을 특징으로 한다.Accordingly, the present invention is characterized in that the heat shield plate is integrally formed on the terminal supporting the heater to block the lower opening of the holder.

이하 본 고안을 첨부 도면 제2도 내지 제4도를 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 4.

제2도는 본 고안에 적용되는 히이터의 지지단자를 형성하는 소재(1)의 형상을 도시한다.2 shows the shape of the material 1 forming the support terminal of the heater applied to the present invention.

소재(1)은 단자부(2)의 상단에 홀더(5)의 외경보다 조금 큰 반경(L)을 갖는 반원상의 차폐판(3)을 일체로 보유함과 아울러, 이 차페판(3)의 중앙측으로 뻗어진 단자부(2)는 접힘선(4)에 따라 절곡되어 제3도의 도시와 같은 지지단자(1')로 형성된다.The material 1 integrally holds a semicircular shielding plate 3 having a radius L slightly larger than the outer diameter of the holder 5 at the upper end of the terminal portion 2, and at the center of the shield plate 3. The terminal portion 2 extending to the side is bent along the fold line 4 and is formed of the supporting terminal 1 'as shown in FIG.

이렇게 만들이지는 지지단자(l')의 단자부(2)로 히이터(H)의 종단이 용접 연결된 다음, 제4도의 도시와 같이 통상적인 전극구조체와 마찬가지로 홀더(5)의 하루에 설치된다.The end of the heater H is welded to the terminal portion 2 of the supporting terminal 1 ', which is made in this way, and is then installed in one day of the holder 5 as in the conventional electrode structure as shown in FIG.

이 경우에 슬라이브(8)의 하측 개구는 지지단자(1')가 보유하는 차폐판(3)에 의해 차단되어 히이터(H)의 열손실을 막아주는 효과를 나타낸다.In this case, the lower opening of the slave 8 is blocked by the shielding plate 3 held by the support terminal 1 ', thereby preventing the heat loss of the heater H.

그리고 차폐판(3)은 홀더(5)의 외경과 보다 조금 큰 반경을 가지고 있기 때문에 1쌍의 지지단자(1')가 상호대칭상으로 배치되면, 홀더(5)의 하측 개구는 서로 대치하는 차폐판(3)에 의해 거의 안전히 차단되어질 수 있다.Since the shielding plate 3 has an outer diameter of the holder 5 and a slightly larger radius, when the pair of support terminals 1 'are arranged in symmetry, the lower openings of the holder 5 face each other. It can be almost safely blocked by the shield plate 3.
