본 고안은 음극 신관용 전자총에 있어서 음극의 히터(Heater)를 지지해주는 히터 지지체에 관한 것이다. 통상적인 음극 구조체는 제1도에 도시되어 있는 바와 같이 음극 슬리브(2)에 음극 캡(1)과 슬리브 지지체(3)를 용접한 다음 혹화 공정에 의한 열처리를 하고, 히터 지지체(5)에 의해 용접되어 지지된 히터(4)를 상기의 음극 슬리브(2)내로 삽입하여서 된 구성체이다.The present invention relates to a heater support for supporting a heater of a cathode in an electron gun for a cathode fuse. A typical negative electrode structure is welded to the negative electrode cap 1 and the sleeve support 3 to the negative electrode sleeve 2, as shown in FIG. 1, and then subjected to a heat treatment by a hardening process, and by the heater support 5 The heater 4 supported by welding is inserted into the said negative electrode sleeve 2, and it is a structure.

상기의 히터 지지체를 확대하여 보면, 제2도에서와 같이 히터 지지체(5)는 히티 용접용 지지체(7)와 이 지지체를 비이드 글래스와 접합하기 위한 보조 지지체(8)의 이체화된 지지체이고, 히터는 상기 지지체(7)의 용접부(6)에서 용접되어 고정된다.In the enlarged view of the heater support, as shown in FIG. 2, the heater support 5 is a transferred support of the support for welding the hitty 7 and the auxiliary support 8 for joining the support to the bead glass. , The heater is welded and fixed at the welded portion 6 of the support 7.

이와 같이 종래의 히터 지지체는 음극 슬리브 하단부의 개방에 의한 열방사 손실이 있었고, 또한 상기 개방부에 의한 열손실을 막기 위해 음극 슬리브와 히터지지체 사이의 간격을 좁히면 히터 용접이 곤란해지는 결점이 있었다.As described above, the conventional heater support has a heat radiation loss due to the opening of the lower end of the cathode sleeve, and the heater welding becomes difficult when the gap between the cathode sleeve and the heater support is narrowed to prevent heat loss caused by the opening. .

따라서, 본 고안은 상기에서 언급한 결점을 개선하기 위해, 음극 슬리브 하단의 개방부를 히터 지지체로 막아 열방사 손실을 줄이고, 히터 용접 공정의 용이성과 히터 지지체의 단순화를 위해 히터 용접용 지지체와 보조 지지체를 일체화 된 음극 선관용 전자총의 히터 지지체를 제공하는 데 그 목적이 있다.Therefore, the present invention reduces the heat radiation loss by blocking the opening of the lower end of the cathode sleeve with the heater support in order to improve the above-mentioned drawbacks, the support for heater welding and the auxiliary support for ease of the heater welding process and simplification of the heater support. Its purpose is to provide a heater support of the electron gun for the cathode ray tube integrated.

다음은 제3도에 의거하여 본 고안의 실시예를 상세히 설명한다.Next, the embodiment of the present invention will be described in detail with reference to FIG.

제3도는 본 고안에 따른 히터 지지체의 사시도로서, 참조번호 9는 종래의 히터 용접용 지지체와 보조 지지체를 일체화시킨 일체형 히터지지체이고, 참조번호 10은 히터(3)를 용접하기 위한 용접부(6)의 히터 라인쪽으로 형성시킨 홈이다.3 is a perspective view of a heater support according to the present invention, reference numeral 9 is an integrated heater support body integrating a conventional heater welding support and an auxiliary support, and reference numeral 10 denotes a weld 6 for welding the heater 3. The groove is formed toward the heater line.

제3도에서. 히터지지체(9)를 단순화 시키기 위해 일체화시켰고, 상기의 지지체(9)의 상면부를 종래의 것보다 넓게 하여 음극 슬리브 하단의 개방부에 의한 열방사 손실을 줄여 음극 특성을 향상시킴과 아울러 지지체의 제작 공정을 간단히 할 수 있게 하였다.In the third degree. In order to simplify the heater support 9, the upper surface of the support 9 is wider than the conventional one, thereby reducing the heat radiation loss caused by the opening of the lower end of the cathode sleeve, thereby improving the negative electrode characteristics and producing the support. The process was simplified.

그리고 히터와 지지체(3) 간의 용접을 용이하도륵 일체형 히터 지지체(9)의 측면에 원형의 홈(10)이 형성되게 하였다.The circular groove 10 is formed on the side surface of the integrated heater support 9 to facilitate welding between the heater and the support 3.

이상에서 설명한 바와 같이 본 고안에 의하면 일체형 히터 지지체는 음극 특성을 개선 시킴과 동시에 제조공정을 단군화시킬 수 있는 실용성이 있다.As described above, according to the present invention, the integrated heater supporter has the utility to improve the negative electrode characteristics and to shorten the manufacturing process.
