Description

플라이백 트랜스포머의 고압보빈 절연장치{An Insulating Device For High Voltage Bobbin Of FBT}An Insulating Device For High Voltage Bobbin Of FBT}

본 발명은 플라이백 트랜스 포머(이하 " FBT"라함)에 있어서, 저압보빈 외측의 고압보빈 양단에 형성되는 보강판의 일측에 이와 분리되는 지지편을 일체로 형성한후 그 외측에 절연수지를 충진함으로써 고압코일이 권선되는 고압보빈에 동일한 강도를 유지토록함과 동시에 고압보빈의 절연거리를 충분히 확보토록 하여 전압차에 의한 쇼트 발생을 미연에 방지하는 플라이백 트랜스포머의 고압보빈 절연장치에 관한 것이다.The present invention is a flyback transformer (hereinafter referred to as "FBT"), one side of the reinforcing plate formed on both ends of the high-pressure bobbin outside the low-pressure bobbin integrally formed with a support piece separated therefrom and filled with an insulating resin on the outside Therefore, the present invention relates to a high voltage bobbin insulation device for a flyback transformer, which maintains the same strength to the high voltage bobbin to which the high voltage coil is wound, and at the same time, ensures sufficient insulation distance of the high voltage bobbin to prevent short circuit due to voltage difference.

일반적으로 알려져 있는 종래의 FBT에 있어서는, FBT케이스의 내부에 설치되면서 코일이 권선되는 고압 및 저압보빈을 통하여 고전압을 발생시키고, 상기 보빈에 권선되는 코일을 통하여 발생되는 전압을 애노드 케이블에 의해 브라운관등에 공급토록 하며, 이때 상기 FBT의 케이스 일측으로 포커스 및 스크린 전압을 가변시키는 포커스유니트가 설치된다.In general known FBT, the high voltage is generated through the high and low pressure bobbins in which the coil is wound while being installed inside the FBT case, and the voltage generated through the coil wound in the bobbin is applied to the CRT tube by the anode cable. In this case, a focus unit for varying the focus and the screen voltage is installed at one side of the case of the FBT.

그리고, 상기 포커스 유니트는, 브라운관내의 볼륨기판상에 일정 형상의 저항체 패턴을 인쇄한후 저항체 패턴에 탄성 지지토록 형성되는 슬라이더를 이용 포커스 및 스크린 전압을 가변시켜 주는 역할을 수행하게 되는 것이다.The focus unit serves to change the focus and the screen voltage by using a slider formed to elastically support the resistor pattern after printing a resistor pattern having a predetermined shape on the volume substrate in the CRT.

이와같은 기술과 관련된 종래의 FBT의 고압보빈에 있어서는 도1 및 도2에 도시한 바와같이, 외경측에 저압코일(10)이 일체로 권선되는 저압보빈(15)이 설치되어 그 외측면에 고압코일(20)이 권선되는 고압보빈(25)이 삽입되고, 상기 고압보빈(25)의 외경측 둘레에 절연필름(30)을 개재하여 이에 권선되는 고압코일(20)을 지지토록 지지턱(35)을 갖는 보강판(40)이 양단에 일체로 돌출 형성되며, 상기 저압보빈(15)이 삽입되는 고압보빈(25)을 삽입토록 FBT케이스(50)가설치되어 그 내측에 삽입되는 저압보빈(15) 및 고압보빈(25)의 외측에 절연수지(55)가 일체로 충진되고, 상기 FBT 케이스(50)와 저압보빈(15)에 지지토록 페라이트 코아(60)가 설치되는 구성으로 이루어 진다.In the conventional high-pressure bobbin of the FBT associated with such a technique, as shown in Figs. 1 and 2, the low-pressure bobbin 15, in which the low-pressure coil 10 is integrally wound, is installed on the outer diameter side thereof, The high pressure bobbin 25 in which the coil 20 is wound is inserted, and the support jaw 35 supports the high pressure coil 20 wound around the outer diameter side of the high pressure bobbin 25 via the insulating film 30. Reinforcement plate 40 having a) protruding integrally formed at both ends, the FBT case 50 is installed so that the high-pressure bobbin 25 is inserted into the low-pressure bobbin 15 is inserted into the low-pressure bobbin ( 15) and the insulating resin 55 is integrally filled on the outside of the high-pressure bobbin 25, the ferrite core 60 is installed to support the FBT case 50 and the low-pressure bobbin (15).

상기와 같은 종래의 FBT 고압보빈은, 저압보빈(15)의 저압코일(10) 출력단으로부터 전달되는 전압을 고압코일(20)의 입력단에 전달할 때, 고압보빈(25)의 외측면에 절연필름(30)을 개재하여 적층 권선되는 고압코일(20)에 의해 전압을 상승시켜 고압보빈(25)의 출력측에서 고전압을 발생시키고, 상기 고압보빈(25)에서 발생되는 전압의 누설을 방지토록 고압보빈(25)이 삽입되는 FBT케이스(50)의 내측에 절연수지(55)가 충진토록 된다.Conventional FBT high pressure bobbin as described above, when the voltage transmitted from the low pressure coil 10 output terminal of the low pressure bobbin 15 to the input terminal of the high pressure coil 20, the insulating film ( The voltage is increased by the high-pressure coil 20 that is laminated and wound through 30 to generate a high voltage at the output side of the high-pressure bobbin 25, and to prevent leakage of the voltage generated by the high-pressure bobbin 25 ( The insulating resin 55 is filled inside the FBT case 50 into which 25 is inserted.

이때, 일반적으로 상기 보빈(25)면은 1㎸/㎜의 내전압을 갖도록 설계되며, 상기 보빈(25)의 측면에 충진되는 절연수지(55)는 10㎸/㎜을 내전압을 갖도록 설계되고, 고압부로 갈수록 절연거리를 충분히 확보해 주어야 하는 것이다.At this time, the bobbin 25 surface is generally designed to have a withstand voltage of 1 kV / mm, and the insulating resin 55 filled in the side surface of the bobbin 25 is designed to have a withstand voltage of 10 kV / mm, As you go, the insulation distance should be secured enough.

그러나, 상기와 같은 FBT 고압보빈은, 고압코일(20)이 고압보빈(25)과 절연수지(55)에 의해 절연될 때 상대적으로 적게 충진되는 절연수지(55)를 통하여 누설되어 전압차에 의한 쇼트가 발생됨으로써 제품에 신뢰성을 해치게 되는 등의 문제점들이 있었던 것이다.However, as described above, the FBT high pressure bobbin is leaked through the insulation resin 55 which is relatively filled when the high pressure coil 20 is insulated by the high pressure bobbin 25 and the insulation resin 55, and is caused by the voltage difference. There was a problem such as a short caused the reliability of the product.

본 발명은 상기와 같은 종래의 여러 문제점들을 개선시키기 위한 것으로서 그 목적은, 고압보빈에 동일한 강도를 유지토록 하면서도 고압보빈과의 절연거리를충분히 확보토록 하여 전압누설에 의한 쇼트 발생을 미연에 방지하고, 전압의 누설을 최소화 함으로써 FBT의 신뢰성 저하를 방지하게 되는 플라이백 트랜스포머의 고압보빈 절연장치를 제공하는데 있다.The present invention is to improve the various problems as described above, and its purpose is to maintain the same strength in the high-pressure bobbin, while sufficiently securing the insulation distance with the high-pressure bobbin to prevent the occurrence of short circuit due to voltage leakage in advance. Therefore, the present invention provides a high voltage bobbin insulation device for a flyback transformer that prevents the FBT from decreasing reliability by minimizing voltage leakage.
