이 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 편향요크의 수평 및 수직편향코일에서 발생되는 극초저주파(Extremely Low Frequency)를 차폐시키면서 흡수할 수 있도록 한 편향요크의 초저주파 방지장치에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to an ultra low frequency prevention device of a deflection yoke capable of absorbing while shielding an extremely low frequency generated in a horizontal and vertical deflection coil of a deflection yoke.
일반적으로 모니터등과 같은 단말표시장치(Video Display Terminal ; 이하 VDT라 약칭함)의 음극선관(CRT)에 사용되는 편향요크는 여러형태가 있으나 크게 새들-트로이달형(Saddle-Toroidal Type)과 새들-새들형(Saddle-Saddle Type)으로 분류되어지며, 제1도에서 종래의 새들트로이달형 편향요크를 개략적으로 나타내어 설명한다.Generally, the deflection yoke used in the cathode ray tube (CRT) of a video display terminal (hereinafter referred to as VDT), such as a monitor, has many types, but is mainly a saddle-toroidal type and a saddle-. It is classified as a saddle type (Saddle-Saddle Type), and in Fig. 1 will be described by schematically showing a conventional saddle-tooth type deflection yoke.
상기 새들트로이달형 편향요크(10)는 네크부(11)와 스크린부(12)로 이루어지는 코일세퍼레이터(13)의 내측에 새들형으로 수평편향코일(14)이 감겨져 장착되며, 외측에는 트로이달형으로 수직편향코일(15)이 감겨진 페라이트코어(16)가 코어클램프(17)에 의해 조립된다.The saddle-shaped deflection yoke 10 has a saddle-shaped horizontal deflection coil 14 wound around the inner side of the coil separator 13 including the neck portion 11 and the screen portion 12, and a troidal type on the outside. The ferrite core 16 on which the vertical deflection coil 15 is wound is assembled by the core clamp 17.
또한, 상기 새들-트로이달형 편향요크(10)를 음극선관의 네크부에 장착한 후에, 수평 및 수직편향코일(14), (15)에 톱니파 펄스를 인가시키게 되면 플레밍의 왼손법칙에 의해 자계가 형성되어 전자총에서 방사되는 R(적색), G(녹색), B(청색)의 전자빔을 편향시켜 화면상에 주사위를 결정한다.In addition, after the saddle-troided deflection yoke 10 is mounted on the neck portion of the cathode ray tube, when a sawtooth pulse is applied to the horizontal and vertical deflection coils 14 and 15, the magnetic field is caused by the Fleming's left hand law. The dice are formed on the screen by deflecting the R (red), G (green), and B (blue) electron beams emitted from the electron gun.
그러나, 새들-트로이달형 편향요크(10)의 수평 및 수직편향코일(14), (15)에 의해 형성되는 자계로부터 누설자속이 발생되는 것으로, 상기 수평편향코일(14)에서는 2~400KHzz의 초저주파(Very Low Frequency)가 발생되며, 수직편향코일(15)에서는 5~2000Hz의 극초저주파가 발생되어 모니터등의 기기내에서 간섭 및 노이즈(Noise)발생의 주요원인으로 작용될 뿐만 아니라, 특히 극초저주파수는 VDT증후군등의 주요원인으로 인체에 악영향을 끼치게 되는바, 이에대한 대책으로 국제적인 안전규격에서는 누설자속의 양이 일정치를 초과할 수 없도록 규제하고 있다.However, the leakage magnetic flux is generated from the magnetic field formed by the horizontal and vertical deflection coils 14 and 15 of the saddle-troidal deflection yoke 10, and the horizontal deflection coil 14 has a second of 400 KHzz. Very low frequency is generated, and very low frequency of 5 ~ 2000Hz is generated in the vertical deflection coil 15, which not only acts as a main cause of interference and noise generation in equipment such as a monitor, but also extremely ultra Low frequency is the main cause of VDT syndrome and other adverse effects on the human body. As a countermeasure, the international safety standard regulates that the amount of leakage flux cannot exceed a certain value.
따라서, 상기 누설자속을 방지하기 위하여 여러가지 수단들이 사용되고 있으며, 수평편향코일(14)의 자계에 의해 발생되는 초저주파를 방지하기 위해서는 누설자속 감쇠용 코일(Caneller Coil)을 코일세퍼레이터(13)에 설치하며, 수직편향코일(15)의 자계에 의해 발생되는 극초저주파를 방지하기 위해 새들-트로이달형 편향요크에서 새들-새들형 편향요크의 사용이 증가하는 추세에 있다.Therefore, various means are used to prevent the leakage magnetic flux, and in order to prevent the ultra low frequency generated by the magnetic field of the horizontal deflection coil 14, a leak magnetic flux damping coil (Caneller Coil) is installed in the coil separator 13. In order to prevent the ultra-low frequency generated by the magnetic field of the vertical deflection coil 15, the use of the saddle-saddle deflection yoke in the saddle-troidal deflection yoke is increasing.
즉, 코일세퍼레이터(13)의 외측면에 새들형으로 수직편향코일(도시하지 않음)을 감아서 장착하며, 그 외측에 페라이트코어를 코어클램프로 조립하는 것이나, 이는 수직편향코일을 새들형으로 감아주기 위해서는 코일권선기를 교체해야 하는 등 설비투자가 증가될 뿐만 아니라, 새들-새들형 편향요크에서도 극초저주파를 완전하게 방지할수 없는 문제점이 있었다.That is, a vertical deflection coil (not shown) is wound on the outer surface of the coil separator 13 in a saddle shape, and a ferrite core is assembled into the core clamp on the outer side thereof, which winds the vertical deflection coil in a saddle shape. In addition to the increase in equipment investment, such as the need to replace the coil winding machine, there was a problem that can not prevent the ultra-low frequency even in the saddle-saddle-type deflection yoke.
이 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 이 고안의 목적은 코일세퍼레이터에 장착되는 수직편향코일의 외측이 금속선으로 만든 그물을 절연시킨 실드부재로 감싸지도록 함으로써, 상기 수직편향코일에서 발생되는 극초저주파가 실드부재에 차폐되면서 흡수되어 국제적인 안전규격을 만족할수 있으며, 극초저주파로 인한 기기내의 간섭 및 노이즈가 제거됨과 동시에 VDT증후군등 인체에 악영향을 끼치는 주요원인이 제거되므로 제품의 신뢰성을 향상시킬 수 있도록 한 편향요크의 극초저주파 방지장치를 제공하는데 있다.The object of the present invention is to solve the above problems, and an object of the present invention is to allow the outer side of the vertical deflection coil mounted on the coil separator to be wrapped with a shield member insulated with a net made of metal wire, thereby generating the vertical deflection coil. Ultra low frequency is shielded by the shield member and absorbed to meet international safety standards.In addition, interference and noise in the device due to ultra low frequency are eliminated, and major causes that adversely affect the human body such as VDT syndrome are eliminated. It is to provide an ultra low frequency prevention device of a deflection yoke.
상기와 같은 목적을 달성하기 위한 이 고안의 특징은, 네크부와 스크린부로 이루어지는 코일세퍼레이터의 내, 외측에 수평 및 수직편향코일이 각각 감겨져 장착되는 편향요크에 있어서, 상기 수직편향코일의 외측에는 실드부재가 장착되도록 한 편향요크의 극초저주파 방지장치에 있다.A feature of this invention for achieving the above object is a deflection yoke in which horizontal and vertical deflection coils are respectively wound and mounted on the inner and outer sides of a coil separator including a neck part and a screen part, and a shield outside the vertical deflection coil. An ultra-low frequency prevention device for a deflection yoke in which a member is mounted.
이하, 이 고안에 따른 편향요크의 극초저주파 방지장치를 첨부된 도면에 의해 상세하게 설명한다.Hereinafter, the ultra-low frequency prevention device of the deflection yoke according to the present invention will be described in detail with the accompanying drawings.
제2도 및 제3도는 이 고안에 따른 편향요크의 극초저주파 방지장치를 설명하기 위해 바람직한 실시예를 나타낸 도면으로서, 제2도의 편향요크는 새들-트로이달형을 개략적으로 나타낸 정면도이다.2 and 3 is a view showing a preferred embodiment for explaining the ultra-low frequency prevention device of the deflection yoke according to the present invention, the deflection yoke of Fig. 2 is a front view schematically showing the saddle-troyed type.
상기 새들-트로이달 편향요크(20)는 네크부(21)와 스크린부(22)로 이루어지는 코일세퍼레이터(24)의 내측에 새들형으로 감겨지는 수평편향코일(25)이 장착되며, 외측에는 트로이달형으로 수직편향코일(26)이 감겨지는 페라이트코어(27)가 코어클램프(28)에 의해 조립된다.The saddle-troidal deflection yoke 20 has a horizontal deflection coil 25 wound in a saddle shape on the inner side of the coil separator 24 including the neck portion 21 and the screen portion 22. In this month, the ferrite core 27, on which the vertical deflection coil 26 is wound, is assembled by the core clamp 28.
또한, 상기 수직편향코일(26)의 외측에는 적어도 2가닥 이상의 금속선(31a)으로 만든 그물(31)을 절연체(32)로 절연한 실드부재(30)가 감싸지도록 장착되며, 상기 절연체(32)는 절연지나 혹은 절연테이프가 사용되고, 상기 금속선(31a)의 한쪽끝은 클립(34)등을 와이어(33) 연결하여 모니터등과 같은 기기내의 접집주(35)에 접지시키며 다른쪽 끝은 시작선과 끝선을 상호 연결시킨다.In addition, the outer side of the vertical deflection coil 26 is mounted so as to surround the shield member 30 insulated with the insulator 32 the net 31 made of at least two strands of metal wire 31a, the insulator 32 Insulation paper or insulating tape is used, one end of the metal wire (31a) is connected to the wire (33) by the clip (34), etc., and grounded to the land holder (35) in a device such as a monitor, and the other end and the start line Interconnect the end lines.
여기에서, 상기 그물(31)의 금속선(31a)은 동선이 사용되며, 이 그물(32)의 금속선(31a)은 공기보다 투자율 및 전도율이 큰 재질로 변경하여 적용하는 것은 용이하게 이해가능한 것이다.Here, copper wire is used for the metal wire 31a of the net 31, and the metal wire 31a of the net 32 can be easily changed and applied to a material having a higher permeability and conductivity than air.
상술한 바와같이 이 고안에 따른 편향요크의 극초저주파 방지장치는, 실드부재(30)가 장착된 새들-트로이달형 편향요크(20)를 음극선관에 장착한 후에 수평 및 수직편향코일(24),(25)에 톱니파 펄스를 인가시키게 되면 플레밍의 왼손법칙에 의해 자계가 형성되어 전자총에서 방사되는 R, G, B의 전자빔을 편향시켜 화면상에 주사위치를 결정한다.As described above, the ultra-low frequency prevention device of the deflection yoke according to the present invention includes a horizontal and vertical deflection coil 24 after mounting the saddle-troidal deflection yoke 20 having the shield member 30 to the cathode ray tube. When a sawtooth pulse is applied to (25), a magnetic field is formed by Fleming's left-hand law to deflect the R, G, and B electron beams emitted from the electron gun to determine dice on the screen.
이때, 상기 수직편향코일(25)에 의해 형성되는 자계로부터 누설자속, 즉 극초저주파가 발생되는 것으로, 상기 극초저주파는 실드부재(30)에 의해 차폐되면서 그물(31)을 구성하는 금속선(31a)에 흡수되어 유도기전력을 발생시킨다.At this time, the leakage magnetic flux, that is, very low frequency is generated from the magnetic field formed by the vertical deflection coil 25, the ultra low frequency is shielded by the shield member 30, the metal wire 31a constituting the net 31 Is absorbed to generate induced electromotive force.
그리고, 상기 유도기전력은 금속선(31a)과 연결된 와이어(33)를 통해 기기내의 접지부(35)에 전달되어 수직편향코일(25)에서 발생되는 극초주파 방지되며, 상기 실드부재(30)는 수평편향코일(14)에서 발생되는 초저주파 역시 감쇠시킬수 있으므로 간단한 구조로 국제적인 안전규격을 만족할 수 있는 새들-트로이달형 편향요크(20)를 제작할 수 있다.In addition, the induced electromotive force is transmitted to the ground part 35 in the device through the wire 33 connected to the metal wire 31a to prevent the ultra-high frequency generated in the vertical deflection coil 25, the shield member 30 is horizontal The ultra-low frequency generated from the deflection coil 14 can also be attenuated, so that the saddle-troided deflection yoke 20 can be manufactured with a simple structure to satisfy international safety standards.
또한, 상기 극초저주파에 의한 기기내의 간섭 및 노이즈가 제거되어 각 부품의 정상적인 작동이 용이하게 수행되며, VDT증후군등과 같이 인체에 악영향을 끼치는 주요원인이 제거되므로 제품의 신뢰성이 향상된다.In addition, since the interference and noise in the device by the ultra-low frequency is removed, the normal operation of each component is easily performed, and the main causes of adverse effects on the human body, such as VDT syndrome, are removed, thereby improving product reliability.
한편, 새들-새들형 편향요크에서는 이미 설명된 바와같이, 코어클램프에 의해 조립된 페라이트코어의 외측에 실드부재(30)를 장착하면, 수직편향코일에서 발생되는 극초저주파가 페라이트코어에서 1차로 차폐되고,상기 페라이트코어에서 차폐되지 못한 극초저주파는 실드부재(30)에서 2차로 차폐되면서 그물(31)을 구성하는 금속선(31a)에 흡수되어 효과적으로 방지된다.On the other hand, in the saddle-saddle deflection yoke, as described above, when the shield member 30 is mounted on the outside of the ferrite core assembled by the core clamp, the ultra low frequency generated in the vertical deflection coil is primarily shielded by the ferrite core. And, the ultra-low frequency that is not shielded in the ferrite core is effectively shielded by being absorbed by the metal wire (31a) constituting the net 31 while shielding secondary in the shield member (30).
이상에서와 같이 이 고안에 따른 편향요크의 극초저주파 방지장치는 수직편향코일의 외측에 금속선으로 만든 그물을 절연한 실드부재가 장착되어 극초저주파를 방지함으로써, 국제적인 안전규격을 만족할 수 있으며 기기내의 간섭 및 노이즈가 제거됨과 동시에 인체에 악영향을 끼치는 주요원인이 제거되어 제품의 신뢰성을 향상시킬 수 있는 유용한 고안인 것이다.As described above, the ultra low frequency prevention device of the deflection yoke according to the present invention is equipped with a shield member insulated with a net made of a metal wire on the outside of the vertical deflection coil, thereby preventing the ultra low frequency, thereby satisfying international safety standards and preventing interference in the equipment. And the noise is removed and at the same time the main cause that adversely affects the human body is removed is a useful design to improve the reliability of the product.
