본 고안은 텔레비전 수상기 및 모니터 등의 기기에서 음극선관으로 공급되는 고압을 비롯하여 히터전압 등을 발생하는 플라이백 트랜스에 1차코일 및 3차코일을 권선하는 플라이백 트랜스의 저압코일 권선구조에 관한 것으로 특히 저압보빈의 기저부에 1차코일 및 3차코일을 함께 권선하여 3차코일로 유도되는 저압의 시간지연이 발생되지 않도록 하는 플라이백 트랜스의 저압코일 권선구조에 관한 것이다.The present invention relates to a low-voltage coil winding structure of a flyback transformer winding the primary coil and the tertiary coil to a flyback transformer that generates a heater voltage, as well as a high pressure supplied to a cathode ray tube from a device such as a television receiver and a monitor. The present invention relates to a low pressure coil winding structure of a flyback transformer for winding a primary coil and a tertiary coil together at a base of a low pressure bobbin so that a low pressure time delay induced by the tertiary coil is not generated.
일반적으로 텔레비전 수상기 및 모니터 등과 같이 음극선관을 사용하는 기기들은 플라이백 트랜스를 사용하여 음극선관의 애노드 등에 인가되는 고압과, 음극선관에 내장되어 있는 전자총이 히터에 인가되는 저압 등을 발생하고 있다.In general, devices using a cathode ray tube such as a television receiver and a monitor generate a high pressure applied to an anode of a cathode ray tube using a flyback transformer, and a low pressure such that an electron gun embedded in the cathode ray tube is applied to a heater.
즉, 플라이백 트랜스는 저압보빈에는 1차코일 및 3차코일을 권선하고, 고압보빈에는 2차코일을 권선하여 1차코일에 수평출력의 플라이백 펄스신호가 인가됨에 따라 2차코일 및 3차코일에 고압 및 저압이 유도되게 하며, 2차코일로 유도된 고압은 음극선관의 애노드를 비롯하여 고압을 필요로 하는 각 부위에 공급하며, 3차코일로 유도된 저압은 히터의 전원으로 사용하고 있다.That is, the flyback transformer winds the primary coil and the tertiary coil to the low pressure bobbin, and the secondary coil to the high pressure bobbin to apply the secondary coil and the tertiary coil as the flyback pulse signal of the horizontal output is applied to the primary coil. High pressure and low pressure are induced in the coil, and the high pressure induced by the secondary coil is supplied to each part requiring high pressure including the anode of the cathode ray tube, and the low pressure induced by the third coil is used as a power source for the heater. .
이러한 플라이백 트랜스를 제조함에 있어서 종래에는 제1도에 도시된 바와 같이 저압보빈(1)에 1차코일(2)을 권선함과 아울러 저압보빈(1)에 기권부(3)를 일체로 형성하여 기권부(3)에 3차코일(4)을 권선하였다.In manufacturing such a flyback transformer, as shown in FIG. 1, the primary coil 2 is wound around the low pressure bobbin 1 and the winding portion 3 is integrally formed on the low pressure bobbin 1. By winding the tertiary coil (4) to the winding portion (3).
그러나 상기와 같은 종래의 기술은 1차코일(2) 및 3차코일(4)이 각기 저압보빈(1)에 각기 분리되어 권선되므로 1차코일(2) 및 3차코일(4)의 결합도가 낮고, 이로 인하여 1차권선(2)에 플라이백 펄스신호를 인가하여 3차코일(4)에 저압이 유도되게 할 경우에 3차코일(4)로 유도되는 저압은 제2도에 도시된 바와 같이 수평펄스신호보다 약간 지연되어 유도되고, 이로 인하여 화면의 우측부위에 백색 바(bar)가 발생하게 되어 화질을 해치고, 사용자에게 불쾌감을 줌은 물론 제품에 대한 신뢰성을저하시키게 되는 등의 문제점이 있었다.However, in the conventional technique as described above, since the primary coil 2 and the tertiary coil 4 are separately wound on the low pressure bobbin 1, the coupling degree of the primary coil 2 and the tertiary coil 4 is When the low pressure is induced in the tertiary coil 4 by applying a flyback pulse signal to the primary winding 2, the low pressure induced by the tertiary coil 4 is shown in FIG. As a result, it is delayed slightly than the horizontal pulse signal, which causes a white bar on the right side of the screen, thereby degrading the image quality, causing inconvenience to the user, and degrading reliability of the product. There was this.
본 고안은 상기와 같은 종래의 제반 문제점들을 해결하기 위하여 고안한 것으로서, 저압보빈의 기권부에 1차코일 및 3차코일을 함께 권선하여 결합도를 향상시킴으로써 3차코일로 유도되는 저압의 시간지연을 방지하여 화면에 백색 바가 나타나지 않도록 하는 간단한 구성의 플라이백 트랜스의 저압코일 권선구조를 제공하는 데 그 목적이 있는 것으로 이를 첨부된 제3도 및 제4도의 도면을 참조하여 상세히 설명한다.The present invention has been devised to solve the above-mentioned problems, and the time delay of the low pressure induced by the tertiary coil by winding the primary coil and the tertiary coil together in the winding portion of the low pressure bobbin to improve the bonding The purpose of the present invention is to provide a low voltage coil winding structure of a flyback transformer having a simple configuration to prevent white bars from appearing on the screen, which will be described in detail with reference to FIGS. 3 and 4.
제3도는 본 고안이 저압코일 권선구조를 보인 개략 단면도로서 이에 도시된 바와 같이, 저압보빈(11)에 1차코일(12)을 권선함과 아울러 기권부(13)를 일체로 형성하고, 이 기권부(13)에 상기 1차권선(12)과 직렬로 연결되는 1차권선(12A) 및 3차권선(14)을 함께 권선하였다.3 is a schematic cross-sectional view showing a low pressure coil winding structure of the present invention, as shown therein, the primary coil 12 is wound around the low pressure bobbin 11, and the winding portion 13 is integrally formed, and The primary winding 12A and the tertiary winding 14, which are connected in series with the primary winding 12, were wound on the winding portion 13 together.
이와 같이 구성된 본 고안은 종래와 마찬가지로 1차코일(12)에 플라이백 펄스신호가 입가됨에 따라 3차코일(14)로 저압이 유도되고, 유도된 저압은 음극선관에 내장된 전자총의 히터에 공급되는 것으로서 이때, 본 고안은 저압보빈(11)의 기권부(13)에 1차코일(12A) 및 3차코일(14)을 함께 권선하였으므로 1차코일(12A)과 3차코일(14)간의 결합도가 매우 높게 된다.According to the present invention configured as described above, as the flyback pulse signal enters the primary coil 12 as in the related art, low pressure is induced to the third coil 14, and the induced low pressure is supplied to the heater of the electron gun embedded in the cathode ray tube. In this case, since the present invention wound the primary coil 12A and the tertiary coil 14 together on the winding portion 13 of the low pressure bobbin 11, the primary coil 12A and the tertiary coil 14 were separated. The bond is very high.
그러므로 제4도에 도시된 바와 같이 3차코일(14)로 유도되는 저압과 수평 펄스신호간에는 시간지연 및 파형의 찌그럼짐이 발생하지 않게 된다.Therefore, as shown in FIG. 4, time delay and waveform distortion do not occur between the low pressure induced by the tertiary coil 14 and the horizontal pulse signal.
이상에서와 같이 본 고안은 저압보빈의 기권부에 1차코일 및 3차코일 함께 권선하여 3차코일로 유도되는 저압의 시간지연 및 파형의 찌그러짐이 발생하지 않으므로 화면의 우측에 백색 바 등이 발생하지 않고, 이로 인하여 화질이 향상됨은 물론 사용자에게 보다 쾌적하게 화면을 시청하고, 제품에 대한 신뢰성을 향상시키게 되는 등의 효과가 있다.As described above, the present invention does not cause the time delay of the low pressure induced by the 3rd coil and the distortion of the waveform induced by the winding of the primary coil and the tertiary coil together in the winding portion of the low pressure bobbin, so that a white bar occurs on the right side of the screen. Instead, the image quality is improved, and the user can more comfortably watch the screen and improve the reliability of the product.
