플라이백 트랜스포머의 브리더 저항 연결구조 {A structure for connecting bleeder resistrance in flyback transformer}{A structure for connecting bleeder resistrance in flyback transformer}

본 발명은 플라이백 트랜스포머의 브리더 저항 연결구조에 관한 것으로, 더욱 상세하게는 포커스 인출단자에서 브리더 저항에 연결되는 고전압 권선을 코일 권선 공정에서 내부로 인입 연결하여 구조를 단순화함으로써 생산성을 향상시키는 것이다.The present invention relates to a breather resistor connection structure of a flyback transformer, and more particularly, to improve productivity by simplifying the structure by connecting the high voltage winding connected to the breather resistor at the focus lead-out terminal into the coil winding process.

일반적으로 음극선관에 사용되는 텔레비젼 수상기의 플라이백 트랜스포머는 수평편향 출력의 귀선시간에 생기는 펄스를 이용하여 수상관용 고압을 얻는 단권 변압기이다.Generally, the flyback transformer of a television receiver used for a cathode ray tube is a single winding transformer which obtains the high voltage for a water pipe using the pulse which arises in the return time of a horizontal deflection output.

이러한, 플라이백 트랜스포머는 외주연에 코일이 권회된 고압보빈과 저압보빈이 중첩되어 하우징 내에 배치되고, 하우징의 일측에는 수상관에 적정한 포커스 전압 및 스크린전압을 공급하는 포커스 팩이 결합되며, 고압 보빈의 고전압 출력단과 포커스 팩의 포커스 및 스크린 출력단과의 사이에는 직사각형의 기판에 저항체를 박막 형태로 도포한 브리더 저항이 연결된다.Such a flyback transformer is disposed in a housing in which a high-pressure bobbin wound around a coil and a low-pressure bobbin are superposed on the outer circumference thereof, and one side of the housing is combined with a focus pack for supplying an appropriate focus voltage and screen voltage to the water pipe, and a high-pressure bobbin Between the high voltage output terminal of the focus pack and the focus and screen output terminal of the focus pack, a breather resistor coated with a resistor in a thin film form on a rectangular substrate is connected.

그런데, 종래 기술의 음극선관용 브러더 저항 연결구조는 도 1에서 도시한 바와 같이 고압 보빈(10)의 몸체부(12)에 코일(13)을 다수 회 권회하고 각 고압 단자핀(14)에 연결하되 고압 단자핀(14)에 고전압 권선(11)으로 연결된 저항(20)과 다이오드(30)로 전압을 승격시켜 고전압 출력단(15)을 통하여 고압을 발생한다.By the way, in the conventional cathode resistor tube connection structure for the cathode ray tube as shown in Figure 1 wound the coil 13 to the body portion 12 of the high-pressure bobbin 10 a number of times and connected to each high-voltage terminal pin (14), The high voltage is generated through the high voltage output terminal 15 by promoting the voltage to the resistor 20 and the diode 30 connected to the high voltage terminal pin 14 by the high voltage winding 11.

이때, 몸체부(12)의 일측면에 설치한 브리더 저항 지지대(17)에 삽입된 브리더 저항(40)은 포커스 인출단자(16)에서 고전압 권선(11)이 다이오드(30)의 상부를 통과하기 위하여 가이드(50)나 별도의 고전압 권선의 선로를 만들어 주어야 함으로써, 플라이백 트랜스 포머의 크기가 확장되고 다이오드의 간섭에 의해서 연결 작업이 난해하여 불량이 발생하여 생산능력이 저하되는 문제점이 있었다.At this time, the breather resistor 40 inserted into the breather resistance support 17 installed on one side of the body portion 12 allows the high voltage winding 11 to pass through the upper portion of the diode 30 at the focus lead terminal 16. In order to make a line of the guide 50 or a separate high voltage winding in order, the size of the flyback transformer is expanded, the connection work is difficult due to the interference of the diode, there is a problem that the failure occurs and the production capacity is reduced.

본 발명은 전술한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 그 목적으로 하는 바는 포커스 팩과 고전압 출력단 사이에 연결되는 브리더 저항의 포커스 인출단자와 연결되는 고전압 권선을 코일 권선 공정에서 내부로 인입 연결하여 구조를 단순화함으로써 작업효율이 증대하여 생산성을 증대하는 음극선관용 플라이백 트랜스포머의 브리더 저항 연결구조를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object thereof is to introduce a high voltage winding connected to a focus lead terminal of a breather resistor connected between a focus pack and a high voltage output terminal into a coil winding process. It is to provide a breather resistor connection structure of a flyback transformer for cathode ray tube which increases the work efficiency by increasing the efficiency by connecting and simplifying the structure.
