본 고안은 직열형 음극구조체에 관한 것으로서, 더 상세하게는 열전자 방출물질이 그 외주면에 코팅된 히이터를 지지하는 히이터 지지체의 개선에 관한 것이다.The present invention relates to a direct type cathode structure, and more particularly, to an improvement in a heater support for supporting a heater coated with a hot electron emitter on its outer circumferential surface.

직열형 음극구조체는 뷰파인더와 같은 초소형 음극선관의 전자총에 사용되는 것으로서, 그 통사적인 구조를 제1도에 나타내 보였다.The series cathode structure is used for an electron gun of a micro cathode ray tube such as a viewfinder, and its syntactic structure is shown in FIG.

이것은 그 내측면에 적어도 한쌍의 스토퍼(2a)가 형성된 대략 캔형의 제어전극(2)에 한쌍의 히이터지지체(3)가 지지되는 인슐레이터(4)가 삽입지지되고 상기 인슐레이터(4)가 삽입된 상기 제어전극(2)의 내측에는 인슐레이터(4)가 제어전극(2)으로부터 이탈되는 것을 방지하는 리테이터(5)가 용접고정된다. 그리고 상기 각 히이터 지지체(3)의 단부에는 히이터 용접면(3a)이 형성되어 그 외주면에 전자방사물질이 도포된 히이터(6)가 용접된다. 여기에서 상기 인슐레이터(4)를 지지하는 스토퍼(2a) 대신에 제어전극(2)에 삽입되는 스페이서를 사용하여도 무방하다.This is because the insulator 4 on which the pair of heater supports 3 are supported is inserted into the substantially can-shaped control electrode 2 having at least one pair of stoppers 2a formed therein, and the insulator 4 is inserted therein. Inside the control electrode 2, a retainer 5 which prevents the insulator 4 from being separated from the control electrode 2 is welded. The heater welding surface 3a is formed at the end of each heater support 3, and the heater 6 coated with the electromagnetic radiation material is welded to the outer peripheral surface thereof. Here, a spacer inserted into the control electrode 2 may be used instead of the stopper 2a supporting the insulator 4.

이와같이 구성된 종래 직열형 음극구조체(1)는 히이터 지지체(3)의 히이터 용접면(3a)이 평면상으로 형성되어 있으므로 히이터(6)의 단부를 소망하는 위치에 정확하게 용접할 수가 없었다. 즉, 상기 인슐레이터(4)에 고정된 히이터 지지체(3)의 히이터 정확한 용접위치를 착을 수 없을 뿐만 아니라 히이터가 평면을 따라 미끄러져 설정된 용접위치에 정확하게 용접할 수 없게 되는 것이다.Since the heater welding surface 3a of the heater support body 3 is formed in planar shape, the conventional direct type negative electrode structure 1 comprised in this way was not able to weld the edge part of the heater 6 to a desired position correctly. That is, not only can the heater not be welded to the correct welding position of the heater support 3 fixed to the insulator 4, but also the heater cannot slide correctly along the plane to be welded correctly to the set welding position.

상기와 같이 히이터(6)가 히이터 지지체(3)의 용접 위치에 정확하게 용접되지 않게 되면 상기 제어전극(2)의 전자빔통과공의 중심과 정확하게 일치하지 않게 되어 컷오프 에미션특성이 저하되게 되는 문제점을 야기시키게 된다.As described above, when the heater 6 is not accurately welded to the welding position of the heater supporter 3, the heater 6 does not exactly coincide with the center of the electron beam through hole of the control electrode 2, thereby reducing the cutoff emission characteristics. Cause it.

본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로서, 전자방사물질이 코팅된 히이터를 히이터 용접면이 설정된 위치에 용접할 수 있도록 하여 이를 채용한 전자총의 컷, 오프 에미션특성을 향상시킬수 있는 직열형 음극구조체를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, it is possible to weld a heater coated with an electromagnetic radiation material in the heater welding surface is set to a direct heat type that can improve the cut, off-emission characteristics of the electron gun employing this The purpose is to provide a cathode structure.

상기 목적을 달성하기 위하여 본 고안은 인슐레이터 상에 소정의 간격으로 이격설치되며 히이터 용접면을 가지는 히이터 지지체를 구비하여된 직열형 음극구조체에 있어서, 상기 히이터 용접면에 히이터의 고정위치 설정용 인입홈을 형성하여 된 것을 특징으로 한다.In order to achieve the above object, the present invention has a heater structure having a heater support having a heater welding surface and spaced at predetermined intervals on an insulator, wherein the inlet groove for setting a fixed position of the heater on the heater welding surface is provided. Characterized in that formed.

이하 첨부된 도면을 참조하여 본 고안에 따른 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도에 나타내 보인 본 고안에 따른 직열형 음극구조체(10)는 그 내측면에 렌싱가공하여된 스토퍼(11)를 가지는 제어전극(11a)에 한쌍의 히이터 지지체(12)가 설치된 인슐레이터(13)가 삽입지지되는데, 상기 히이터 지지체(12)의 단부에는 히이터용접면(12a)이 형성되어 이에 전자방사물질이 그 외주면에 코팅된 히이터(14)가 용접된다. 여기에서 상기 히이터 용접면(12a)에는 본 고안의 특징에 따라 상기 히이터(14)의 용접위치를 고정하는 인입홈(12b)이 형성되는데, 이 인입홈(12b)은 상기 각 히이터 지지체(12)의 상호 대향되는 면으로부터 소정폭 후퇴된 위치에 형성된다.In the in-line type cathode structure 10 according to the present invention shown in FIG. 2, an insulator 13 having a pair of heater supports 12 installed on a control electrode 11 a having a stopper 11 lanced on an inner surface thereof is provided. ) Is inserted and supported, the heater welding surface 12a is formed at the end of the heater support 12 so that the heater 14 coated with the electromagnetic radiation material on its outer circumferential surface is welded. Here, the heater welding surface 12a is formed with an inlet groove 12b for fixing the welding position of the heater 14 according to the features of the present invention, the inlet groove 12b is each of the heater support 12 It is formed at a position where the predetermined width is retracted from the mutually opposing surfaces of.

이와같이 구성된 히이터 지지체(12)는 그 히이터 용접면(12a)에 히이터(14)의 용접위치를 설정하는 인입홈(12b)이 형성되어 있으므로 히이터(14)의 단부를 그 설정위치에 용이하게 용접할 수 있다. 즉, 상기 히이터 용접면(12b)에는 히이터(14)의 단부가 용접되는 설정위치에 인입홈(126)에는 히이터(14)의 단부가 용접되는 설정위치에 인입홈(12b)이 형성되어 있으므로 히이터(14)의 용접위치를 용이하게 찾을 수 있으며 상기 히이터(14)단부의 용접시에는 상기 단부가 히이터 용접면(12b)에 대해 미끄러지는 것을 방지할 수 있어 히이터를 설정위치에 용접할 수 있게되는 것이다.The heater support 12 constructed as described above has an inlet groove 12b for setting the welding position of the heater 14 on the heater welding surface 12a, so that the end of the heater 14 can be easily welded to the set position. Can be. That is, since the inlet groove 12b is formed in the setting position where the end of the heater 14 is welded to the heater welding surface 12b at the setting position where the end of the heater 14 is welded, the inlet groove 12b is formed in the heater welding surface 12b. The welding position of (14) can be easily found, and when welding the heater 14 end, the end can be prevented from slipping with respect to the heater welding surface 12b, so that the heater can be welded to the set position. will be.

이와같이 본 고안 직열형 음극구조체는 히이터 지지체의 히이터 용접면에 그 용접위치 설정용 인입홈이 형성되어 있으므로 히이터를 상기 히이터 용접면의 설정위치에 정확하게 용접할 수 있게 된다.As described above, the present invention-type negative electrode structure has an inlet groove for setting the welding position on the heater welding surface of the heater support, so that the heater can be accurately welded to the setting position of the heater welding surface.

따라서 히이터와 제어전극의 전자빔통과공의 센터를 정확하게 맞출수 있게되며 나아가서는 컷, 오프 특성을 향상시킬 수 있어 고해상도의 음극선관 제작이 가능하게 된다.Therefore, the center of the electron beam through hole of the heater and the control electrode can be precisely aligned, and further, the cut and off characteristics can be improved, thereby making a cathode ray tube of high resolution.
