본 고안은 모니터용 편향요크 보정편의 구조에 관한 것으로서, 특히 고주파수를 사용하는 디스플레이(Display)용 모니터의 편향요크에 장착되는 보정편의 구조에 관한 것이다.The present invention relates to a structure of a deflection yoke correction piece for a monitor, and more particularly, to a structure of a correction piece mounted to a deflection yoke of a monitor for a display using a high frequency.
일반적으로, 높은 주파수를 사용하는 디스플레이용 모니터에서 주파수가 높아지면 잔류손, 주울열, 와류손실, 히스테리시스손실등이 발생되는데 이러한 손실들을 최소화하기 위하여 보정편이 장착된다.In general, when the frequency is increased in a display monitor using a high frequency, residual loss, joule heat, eddy current loss, hysteresis loss, etc. are generated, and a correction piece is mounted to minimize these losses.
그러나, 종래의 상기와 같은 모니터에 장착되는 편향요크에는, 주지하는 바와같이 사각막대 형상체의 보정편이 장착되고 있으나 이와같은 보정편을 사용한다해도 손실이 커서 효과가 없기 때문에 보정편의 사용이 억제되어오고 있는 실정이다.However, in the conventional deflection yoke mounted on the monitor as described above, the correction piece of the rectangular bar-shaped body is attached as known, but even if such a correction piece is used, since the loss is large and there is no effect, use of the correction piece is suppressed. It's coming.
또한, 높은 주파수에서 보정편이 그 기능을 발취하기 위하여는 와전류손, 열손실, 주파수특성등에 영향이 적어야만 하는 것이었다.In addition, in order to extract the function at the high frequency, the correction piece had to have little influence on eddy current loss, heat loss, and frequency characteristics.
본 고안은 상기와 같은 문제점을 감안하여 이루어진 것으로서, 본 고안의 목적은 고주파수를 사용하는 디스플레이용 모니터에 적용될수있는 보정편으로서, 전기저항을 높게하여 와류손실을 적게 만들수있는 동시에 각종손실을 최소화하여 보정력을 극대화시킬수 있는 디스플레이용 편향요크의 보정편을 제공하는데 있다.The present invention has been made in view of the above problems, and an object of the present invention is a correction piece that can be applied to a display monitor using a high frequency, and has high electrical resistance to reduce eddy current loss while minimizing various losses. It is to provide a correction piece of the deflection yoke for display that can maximize the correction power.
상기와 같은 목적을 달성하기 위하여 본 고안의 특징은, 고주파수를 사용하는 디스플레이용 모니터에 장착되는 편향요크의 보정편에 있어서, 상기 보정편을 얇은 철편으로 여러장 적층시켜 형성하고, 상기 보정편의 양측부위에 철편의 유동을 방지하기 위하여 유동방지용 돌기를 형성한 것이다.In order to achieve the above object, a feature of the present invention is a correction piece of a deflection yoke mounted on a display monitor using a high frequency, the correction piece is formed by stacking a plurality of pieces of thin iron pieces, both sides of the correction piece In order to prevent the flow of the iron piece to the site is formed a flow preventing projection.
이하, 본 고안의 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail according to the accompanying drawings.
제1도내지 제3도는 본 고안의 실시예를 설명하기 위한 도면으로서, 도면중 부호(1)은 일반적인 편향요크를 나타낸다.1 to 3 are views for explaining an embodiment of the present invention, in which reference numeral 1 denotes a general deflection yoke.
그리고 편향요크(1)의 기본적인 동작은, 수평 및 수직편향코일에 톱니된 펄스가 인가되면 플레밍의 왼손법칙에 의하여 자계가 발생되어, 전자총에서 방사되는 전자빔의 위치를 결정하게 된다.In the basic operation of the deflection yoke 1, when a sawtooth pulse is applied to the horizontal and vertical deflection coils, a magnetic field is generated according to Fleming's left-hand law, which determines the position of the electron beam emitted from the electron gun.
그러나 음주선관의 기구적인 매카니즘에 의한 오차 또는 편향요크자체의 오차에 의하여 원하는 위치에 정확히 주사되기가 곤란하므로 보정수단으로 보정편을 사용하게 된다.However, since it is difficult to accurately scan the desired position due to an error caused by the mechanical mechanism of the drinking vessel or the error of the deflection yoke itself, the correction piece is used as a correction means.
이보정수단의 일원으로 내부에 자성체로 구성된 보정편을 사용하는 서브보빈을 네크부상부에 장착시켜 전자빔이 원하는 주사위치에 주사되도록 하여왔다.As a member of this correction means, a sub bobbin using a correction piece composed of a magnetic material therein has been mounted on the neck portion so that the electron beam can be scanned on the desired dice.
이 편향코일(1)의 네크부(2)에는 보정편(3)이 끼워넣어지는 보빈(4)이 설치되고, 또한 코일분리편(5)의 내외측에는 각각 수평편향코일(6)과 수직편향코일(7)이 고정설치된다.The neck portion 2 of the deflection coil 1 is provided with a bobbin 4 into which the correction piece 3 is fitted, and a horizontal deflection coil 6 and a vertical deflection respectively in the inner and outer sides of the coil separating piece 5. The coil 7 is fixedly installed.
제2도는 본 고안요부의 분리사시도로서, 얇은 철편이 여러장 적층된 보정편(3)이 보빈(4)의 삽입홈(8)에 끼워넣어진다.2 is an exploded perspective view of the essential part of the present invention, in which a plurality of thin iron pieces are stacked in the insertion groove 8 of the bobbin 4.
따라서, 자계가 시간적으로 변할때 (Z방향), X, Y평면에 전압이 유기되고, 전압이 유기됨에 따라 I=E/R 관계에서 전압은 일정하며, 자기저항이 높을 경우에는 전류와 저항은 반비례관계에 있으므로 전류가 적어져서 손실전류가 적어지게 된다.Therefore, when the magnetic field changes in time (Z direction), the voltage is induced in the X and Y planes, and as the voltage is induced, the voltage is constant in the relationship I = E / R, and when the magnetic resistance is high, current and resistance are inversely proportional. As a result, there is less current and less loss current.
또한, 전기저항은 단면적에 비례하므로 얇은 절연보정편(3)을 여러장 겹쳐 사용함으로써, 전기저항을 높게하여 와류손실을 적게하는 작용을 하는 것이다.In addition, since the electrical resistance is proportional to the cross-sectional area, by using a plurality of thin insulation compensation pieces 3 superimposed, the electrical resistance is increased to reduce the eddy current loss.
그러므로, 각종손실을 최소화하는 동시에 보정력을 극대화할수 있는 것이다.Therefore, it is possible to maximize the correction power while minimizing various losses.
제3도의 (A), (B)는 본 고안의 보정편(3)을 분리한 상태의 사시도 및 조립단면도로서, 상기 보정편(3)의 양측에는 유동을 방지시키기 위한 돌기(9), (9')가 형성되어 있어, 각 보정편(3)을 적층시킬때 서로 유동이 없이 적층시킬수가 있다.(A) and (B) of FIG. 3 are a perspective view and an assembled sectional view of the state in which the correction piece 3 of the present invention is removed, and projections 9 and (2) for preventing flow on both sides of the correction piece 3 ( 9 ') is formed so that each of the correction pieces 3 can be stacked without flow to each other.
이상에서와 같이 본 고안은 고주파수를 사용하는 디스플레이용 모니터에 적용시킬수 있는 보정편을 얇은 철편으로 유동없이 적층시킴으로써, 전기저항을 높게하여 와류손실을 적게 만들수 있는 동시에 각종손실을 최소화하여 보정력을 극대화 시킬수 있는 것이다.As described above, the present invention can laminate the correction pieces that can be applied to the monitor for display using high frequency without thin iron pieces, and can increase the electric resistance to reduce the eddy current loss while minimizing the various losses to maximize the correction power. It is.
