본 고안은 음극선관용 전자총의 히이터에 관한 것으로써, 특히 전원인가부의 강도 및 용접성이 향상되도록 개량한 것에 관한 것이다.The present invention relates to a heater of an electron gun for a cathode ray tube, and more particularly, to an improvement to improve the strength and weldability of a power supply unit.
일반적으로 음극선관용 전자총의 히이터는 직선상의 굵은 도전성 금속심선에 방열유효면적과 길이를 확보하기 위하여 발열선을 소정 피치간격으로 감은 다음 이를 히이터의 형상으로 코일링하여 발열부(11)와 전원인가부(12)를 형성하고 상기 발열부(11)에 알루미나(Al2O3) 절연층(13)을 피복한 다음 강산등으로 상기 도전성 금속심선을 제거함으로써 제조한다. (제 1 도 참조)In general, a heater of an electron gun for a cathode ray tube is wound around a heating wire at a predetermined pitch interval in order to secure a heat radiation effective area and length on a straight thick conductive metal core wire, and then coil it in the shape of a heater to generate a heat generating unit 11 and a power supply unit ( 12) is prepared by coating the alumina (Al 2 O 3 ) insulating layer 13 on the heat generating portion 11 and then removing the conductive metal core wire with a strong acid. (See Figure 1)
그러나 이와 같은 종래 음극선관용 전자총의 히이터는 도전성 금속심선이 제거된 상태이므로 절연층(13) 외부로 노출된 전원인가부(12)의 강도가 취약하여 이를 히이터 지지체등에 용접시 전원인가부(12)의 변형이나 파손이 발생되게 되며, 전원인가부(12)를 히이터 지지체등의 소정위치에 정확히 용접하기 어려운 등의 문제점이 있었다.However, since the heater of the conventional cathode ray tube electron gun has the conductive metal core removed, the strength of the power applying unit 12 exposed to the outside of the insulating layer 13 is weak, so that the power applying unit 12 is welded to the heater support. Deformation or breakage may occur, and it is difficult to accurately weld the power supply unit 12 to a predetermined position such as a heater support.
본 고안은 상술한 바와 같은 문제점을 감안하여 안출된 것으로서, 전원인가부의 강도 및 용접성을 향상시킨 음극선관용 전자총의 히이터를 제공함에 그 목적이 있다.The present invention has been made in view of the above problems, and an object thereof is to provide a heater of an electron gun for cathode ray tubes, which has improved the strength and weldability of a power supply unit.
상기의 목적을 달성하기 위하여 본 고안은, 코일스프링형상의 발열선이 코일링되어 발열부와, 전원인가부가 형성되고 상기 발열부에 절연층이 피복형성된 음극선관용 전자총의 히이터에 있어서, 상기 전원인가부가 소정직경과 길이를 가지는 도전성 금속심선에 나선형으로 권회되어 된 것을 점에 그 특징이 있다.In order to achieve the above object, the present invention provides a heater for a cathode ray tube electron gun in which a coil spring-shaped heating wire is coiled to form a heat generating portion and a power applying portion, and an insulating layer is formed on the heat generating portion, Its characteristic is that it is wound spirally on a conductive metal core wire having a predetermined diameter and length.
이하 첨부된 도면을 참조하여 본 고안에 따른 바람직한 일실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 2 도에는 본 고안에 따른 음극선관용 전자총의 히이터가 도시되어 있는 바, 이는 코일스프링 형상의 발열선(1)이 히이터형상으로 코일링 되어 발열부(1a)와 전원인가부(1b)를 형성하되, 상기 발열부(1a)에는 알루미나(Al2O3) 절연층(2)이 피복형성되고, 상기 전원인가부(1b)에는 그 외주에 상기 전원인가부가 권선되는 도전성 금속심선(3)이 마련된다.2 shows a heater of the electron gun for the cathode ray tube according to the present invention, in which the heating wire 1 of the coil spring shape is coiled into a heater shape to form the heating part 1a and the power applying part 1b. The alumina (Al 2 O 3 ) insulating layer 2 is formed on the heat generating part 1a, and the power applying part 1b is provided with a conductive metal core wire 3 around which the power applying part is wound. do.
여기에서 상기 도전성 금속심선(3)은, 발열선(1)의 코일링시 사용되는 도전성 금속심선의 제거시 강산에 발열부(1a)만을 담궈서 발열부(1a)의 도전성 금속심선만을 제거하고 전원인가부(1b)의 도전성 금속심선(3)을 잔류시킴으로써 형성된다.Here, the conductive metal core 3, by removing only the conductive metal core of the heating unit 1a by immersing only the heating unit 1a in a strong acid when removing the conductive metal core wire used in the coiling of the heating wire 1, the power supply unit It is formed by leaving the conductive metal core wire 3 of (1b).
그리고 도전성 금속심선(3)이 상기 전원인가부(1b)로부터 이탈되는 것을 방지함과 동시에 전원인가부(1b)의 용접성이 향상되도록 하기 위하여 전원인가부(1b)를 납작하게 가압변형시킨다.In addition, in order to prevent the conductive metal core wire 3 from being separated from the power supply unit 1b and to improve weldability of the power supply unit 1b, the power supply unit 1b is flatly deformed under pressure.
이와 같이 구성된 본 고안에 따른 음극선관용 전자총의 히이터는 전원인가부(1b)에 도전성 금속심선(3)이 마련되어 있으므로 전원인가부(1b)의 강도가 향상되어 전원인가부의 변형이나 파손이 극소화되게 되며, 전원인가부(1b)가 납작하게 가압변형되어 있으므로 도전성 금속심선(3)이 전원인가부(1b)로부터 이탈되는 것이 방지됨과 동시에 전원인가부의 용접성이 향상되게 된다.In the heater of the cathode ray tube electron gun according to the present invention configured as described above, since the conductive metal core wire 3 is provided in the power supply unit 1b, the strength of the power supply unit 1b is improved to minimize the deformation or damage of the power supply unit. Since the power applying portion 1b is flatly deformed under pressure, the conductive metal core 3 is prevented from being separated from the power applying portion 1b, and the weldability of the power applying portion is improved.
이상에서 설명한 바와 같은 본 고안 음극선관용 전자총의 히이터는 종래 발생되던 전원인가부의 변형이나 파손 및 전원인가부의 용접성 불량등의 제반문제점을 해소시킬 수 있게 되는 이점이 있다.As described above, the heater of the present invention cathode ray tube electron gun has an advantage of solving various problems such as deformation or breakage of the power supply unit and poor weldability of the power supply unit.
