본 고안은 편향요크의 마그네트 고정장치에 관한 것으로서, 더욱 상세하게는 코일세퍼레이터의 스크린부에 설치되어 베럴(Barrel) 및 핀(Pincushion)자계 둥을 수정하는 마그네트가 조립과정에서 극성이 바뀌지 않도록 함으로서, 조립성이 향상되도록한 편향요크의 마그네트 고정장치에 관한 것이다.The present invention relates to a magnet fixing device of the deflection yoke, and more particularly, the magnet is installed on the screen of the coil separator so that the polarity of the magnet that corrects the barrel and the pinhole is not changed in the assembly process. The magnet fixing device of the deflection yoke to improve the assembly.

일반적으로 편향요크(Deflection Yoke)는 CRT의 네크부에 설치되는 것으로서, 제1도에 도시된 바와 같이 수평편향코일(2)과 수직편향코일(3)의 조합으로 구성되며 서로 분리된 한쌍의 코인세페레이터(1) 내주면에 수평편향코일(2)이 설치되고 이의 외주면에 수직편향코일(3)이 설치된다. 또한 수직편향코일(3)의 자계를 보강하기 위해 코일세퍼레이터(1)의 외주면에 서로 분할된 한쌍의 페라이트코어(4)가 구비된다.In general, deflection yoke is installed in the neck portion of the CRT, and is composed of a combination of horizontal deflection coils 2 and vertical deflection coils 3 as shown in FIG. 1 and a pair of coins separated from each other. A horizontal deflection coil 2 is installed on the inner circumferential surface of the separator 1 and a vertical deflection coil 3 is installed on the outer circumferential surface thereof. In addition, a pair of ferrite cores 4 are provided on the outer circumferential surface of the coil separator 1 so as to reinforce the magnetic field of the vertical deflection coil 3.

이처럼 구성된 편향요크는 CRT의 전자층에서 발사된 전자빔을 좌, 우측 및 상, 하측 방향으로 편향시켜 CRT의 형광면 상에 형성된 RGB에 충돌시키는 역할을 한다. 또한 수평, 수직편향코일(2) (3)이 코일세퍼레이터(1)에 조립되는 과정에서 조립오차 등으로 인하여 자계분포가 베럴 또는 핀자계 등으로 변화하기 때문에 이를 보정하기 위해 코일세퍼레이터(1)의 스크린부(5)에 마그네트(6)가 설치된다.The deflection yoke configured as described above deflects the electron beam emitted from the electron layer of the CRT in left, right, up, and down directions to collide with the RGB formed on the fluorescent surface of the CRT. In addition, in the process of assembling the horizontal and vertical deflection coils (2) and (3) to the coil separator (1), the magnetic field distribution is changed to a barrel or pin magnetic field due to assembly errors, etc. The magnet 6 is installed in the screen part 5.

그러나 마그네트(6)를 받이부(7)에 조립하는 과정에서 이의 극성이 바뀐 상태로 조립될 경우 자계분포의 보정이 어렵게 됨으로 마그네트(6)를 분리한 다음 재조립해야 되는 등의 번거로움이 있다.However, in the process of assembling the magnet 6 to the receiving part 7, the magnetic field distribution becomes difficult to be assembled when the polarity thereof is changed. Therefore, the magnet 6 needs to be separated and then reassembled. .

본 고안은 종래의 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 코일세퍼레이터의 스크린부 상에 설치되는 마그네트의 극성이 조립과정에서 바뀌지 않도록 함으로서, 마그네트의 조립성이 향상되도록한 편향요크의 마그네트 고정장치를 재공함에 있다.The present invention was devised to solve the conventional problems, and the object of the present invention is to prevent the polarity of the magnet installed on the screen portion of the coil separator from changing during the assembly process, so that the magnet assembly of the deflection yoke is improved. It is provided with a fixing device.

상기 목적을 달성하기 위하여 본 고안은 코일세퍼레이터에 전자빔을 수평 및 수직방향으로 편향시키는 수평, 수직편향코일이 각각 설치됨에 있어서, 상기 코일세퍼레이터 선단의 스크린부에 상기 각 코일의 베럴 및 핀자계를 조정하는 마그네트가 구비되고 상기 마그네트의 극성이 바뀌지 않도록하는 식별수단이 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 to adjust the barrel and pin magnetic field of each coil in the screen portion of the coil separator tip. It is characterized in that the magnet is provided and the identification means for preventing the polarity of the magnet is changed.

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.

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)와 마그네트(10) 사이에 식별수단(12)이 구비된다. 식별수단(12)은 마그네트(10)가 받이부(11)에 끼워질 때 이의 극성이 뒤바뀌는 것을 방지하는 것으로서, 에컨데 마그네트(10)의 S극에 홈(14)이 형성되고 이와 대응되는 받이부(11)의 내부에 돌기(13)가 각각 형성된다.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. The receiving part 11 into which the magnet 10 is fitted is provided in the screen part 5 of the coil separator 1, and the identification means 12 is provided between the receiving part 11 and the magnet 10. As shown in FIG. The identification means 12 prevents the polarity of the magnet 10 from being reversed when the magnet 10 is fitted to the receiving part 11. For example, a groove 14 is formed in the S pole of the magnet 10 and the receiving part corresponding thereto. The protrusions 13 are formed in the inside of the part 11, respectively.

이처럼 구성된 본 고안은 수평편향코일(2)의 권선불량 또는 조립오차 등으로 인하여 베럴자계 또는 핀자계가 발생될 때 이를 조정하여 균일자계가 형성되도록 마그네트(10)가 받이부(11)에 끼워진다. 이때 마그네트(10)의 어느 한 극성에 홈(14)이 형성되고 이와 대응되는 받이부(11)에 돌기(13)가 각각 형성됨으로 마그네트(10)를 받이부(11)에 끼우면 돌기(13)가 홈(14)에 끼워지면서 서로 조립된다. 따라서 마그네트(10)가 받이부(11)에 끼워질 때 극성이 바뀌지 않는다. 에컨데 극성이 바뀐 상태로 받이부(l1)에 끼워지면 돌기(13)에 마그네트(10)의 저면이 걸려 끼워지지 않는다.In this configuration, the magnet 10 is fitted to the receiving part 11 so as to form a uniform magnetic field by adjusting it when a barrel magnetic field or a pin magnetic field is generated due to a winding defect or an assembly error of the horizontal deflection coil 2. . At this time, the groove 14 is formed at one polarity of the magnet 10 and the protrusions 13 are formed in the receiving part 11 corresponding thereto, so that the projections 13 are inserted when the magnet 10 is inserted into the receiving part 11. Are fitted into the grooves 14 and assembled together. Therefore, the polarity does not change when the magnet 10 is fitted to the receiving part 11. For example, if the polarity of the magnet 10 is inserted into the receiving portion (11) in a state where the bottom surface of the magnet 10 is not caught by the projection (13).

이상에서와 같이 본 고안에 따르면 코일세퍼레이터 스크린부에 마그네트가 설치되는 받이부가 구비된다. 이러한 마그네트는 코일세퍼레이터에 조립되는 수평편향코일의 권선불량 또는 조립오차 등으로 인하여 베럴 및 핀자계가 발성될 때 이를 보정하는 것으로서, 받이부에 끼워지는 마그네트의 극성이 바뀌지 않도록 받이부에 돌기가 형성되고 이와 대응토록 마그네트의 어느 한 극성에 홈이 각각 형성된다. 따라서 마그네트가 받이부에 조립되더라도 극성이 바뀔 우려가 없으므로 조립성이 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 the barrel and the pin magnetic field are uttered due to a winding failure or an assembly error of the horizontal deflection coil assembled in the coil separator. Correspondingly, grooves are formed in either polarity of the magnet. Therefore, even if the magnet is assembled to the receiving portion there is no fear that the polarity is changed, there is an effect such as improved assembly.
