그러나 마그네트(6)를 받이부(7)에 조립된 상태에서 조립오차 등으로 인하여 좌우측 방향으로 유동되어 자계가 변화하기 때문에 균일자계로 보정하기 어려운 등의 단점이 있다.However, since the magnetic field is changed in the left and right directions due to assembly errors, etc. in the state in which the magnet 6 is assembled to the receiving unit 7, there is a disadvantage that it is difficult to correct the uniform magnetic field.
본 고안은 종래의 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 코일세퍼레이터 스크린부 상에 설치되는 마그네트가 조립된 상태에서 좌우측 방향으로 유동되지 않도록 함으로서, 자계를 조정할 수 있도록하여 화면특성이 향상되도록한 편향요크의 마그네트 고정장치를 제공함에 있다.The present invention has been made to solve the conventional problems, and the object of the present invention is to prevent the magnets installed on the coil separator screen portion from flowing in the left and right directions in the assembled state, so that the magnetic field can be adjusted to improve the screen characteristics. To provide a magnet fixing device of the deflection yoke as much as possible.
상기 목적을 달성하기 위하여 본 고안은 코일세퍼레이터에 전자빔을 수평 및 수직방향으로 편향시키는 수평, 수직편향코일이 각각 설치됨에 있어서, 상기 코일세퍼레이터의 선단의 스크린부에 상기 각 코일의 베럴 및 핀자계를 조정하는 마그네트가 구비되고 상기 받이부에 상기 마그네트의 유동을 억제하는 지지수단이 구비된 특징이 있다.In order to achieve the above object, the present invention is provided with horizontal and vertical deflection coils for deflecting an electron beam in a horizontal and vertical direction, respectively, in the coil separator. It is characterized in that the magnet to adjust is provided and the support means for suppressing the flow of the magnet in the receiving portion.
이하 첨부도면에 따라 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention according to the accompanying drawings in detail as follows.
제 2 도는 본 고안 고정장치의 분리 사시도로서, 제 1 도와 동일 구성요소는 동일 부호를 사용하여 본 고안을 설명한다. 코일세퍼레이터(1)의 스크린부(5)에 마그네트(10)가 끼워지는 받이부(11)가 구비되고 받이부(11)의 양측벽 상단에 마그네트(10)의 이탈을 방지하는 걸림턱(13)이 각각 형성된다. 또한 받이부(11)의 양측벽에 내측으로 돌출되어 마그네트(10)의 양측을 밀어 이의 유동을 억제하는 지지수단(12)이 구비된다. 지지수단(12)은 받이부(11)의 양측벽에 내측으로 돌출되어 마그네트(10)의 측벽을 받쳐주는 지지편(14)이 구비된다. 이들 지지편(14)은 마그네트(10)가 받이부(11)에 끼워진 상태에서 유동되지 않도록 해준다.2 is an exploded perspective view of the fixing device of the present invention, the first diagram and the same components will be described using the same reference numerals. A catching part 13 is provided on the screen part 5 of the coil separator 1 to accommodate the magnet 10 to be fitted and prevents the magnet 10 from being detached from the upper end of both side walls of the receiving part 11. ) Are formed respectively. In addition, support means 12 protruding inward to both side walls of the receiving part 11 to push both sides of the magnet 10 to suppress the flow thereof. The support means 12 is provided with support pieces 14 which protrude inwards on both side walls of the receiving part 11 to support the side walls of the magnet 10. These support pieces 14 prevent the magnet 10 from flowing in a state where it is fitted to the receiving part 11.
이처럼 구성된 본 고안은 수평,수직편향코일(2)(3)의 권선불량 또는 조립오차등으로 인하여 베럴자계 또는 핀자계가 발생될 때 이를 조정하여 균일자계가 형성되도록 마그네트(10)가 받이부(11)에 끼워진다. 이때 마그네트(10)가 받이부(11)에 끼워지면 이의 상단이 걸림턱(13)에 걸려 되빠지지 않는다. 또한 끼워진 상태에서 받이부(11)의 양측벽에 형성된 지지편(14)에 의해 좌우측 방향으로의 유동이 억제된다. 따라서 마그네트(10)와 받이부(11) 사이의 조립오차가 감소됨으로 불량자계를 균일자계로 조정할 수 있다.The present invention configured as described above has a magnet 10 receiving part so that a uniform magnetic field is formed by adjusting it when a barrel magnetic field or a pin magnetic field is generated due to a winding failure or an assembly error of the horizontal and vertical deflection coils (2) and (3). 11) is fitted. At this time, when the magnet 10 is fitted to the receiving part 11, the upper end thereof is not caught by the catching jaw 13 so as not to be caught. Further, in the fitted state, flow in the left and right directions is suppressed by the support pieces 14 formed on both side walls of the receiving part 11. Therefore, as the assembly error between the magnet 10 and the receiving part 11 is reduced, the bad magnetic field can be adjusted to a uniform magnetic field.
이상에서와 같이 본 고안에 따르면 코일세퍼레이터 스크린부에 마그네트가 설치되는 받이부가 구비된다. 이러한 마그네트는 코일세퍼레이터에 조립되는 수평,수직편향코일의 권선불량 또는 조립오차 등으로 인하여 베럴 및 핀자계가 발생될 때 이를 보정하는 것으로서, 마그네트가 조립된 상태에서 유동되지 않도록 받이부의 양측벽에 지지편이 각각 형성된다. 따라서 마그네트의 조립오차가 감소됨으로 균일자계의 보정이 정확하게 이루어져 화면특성이 향상되는 등의 효과가 있다.According to the present invention as described above is provided with a receiving portion that the magnet is installed on the coil separator screen portion. This magnet compensates when a barrel or pin magnetic field is generated due to winding failure or assembly error of the horizontal and vertical deflection coils assembled in the coil separator, and is supported on both side walls of the receiving part so that the magnet does not flow in the assembled state. Each side is formed. Therefore, as the assembly error of the magnet is reduced, the correction of the uniform magnetic field is accurately performed, thereby improving the screen characteristics.
