본 고안은 전자제품의 음극선관(CRT)에 장착되어 전자비임을 수평 및 수직으로 편향시키는 편향요크에 있어서, 특히 코일쎄퍼레이터의 외측에 수직코일이 권선되어 취부되는 페라이트코어편 접촉면의 자계 손실을 줄이고 조립을 견고히 하기 위한 페라이트코어 구조에 관한 것이다.The present invention is a deflection yoke mounted on a cathode ray tube (CRT) of an electronic product to deflect the electron beam horizontally and vertically. In particular, a magnetic field loss of a contact surface of a ferrite core piece which is mounted by winding a vertical coil outside the coil separator is installed. A ferrite core structure for reducing and solidifying the assembly.
일반적으로 편향요크용 페라이트코어는 원통형으로서 일체형이면 가장 좋으나 수직 코일을 권선하기 용이하고 코일쎄퍼레이터의 외측에 취부 용이하도록 페라이트코어편으로 형설되어 코일쎄퍼레이터의 외측에 수직코일이 권선된 페라이트코어편을 취부한 후 코어클램프로 고정하여 수평코일 및 수직코일에서 생긴 자계의 외부유출을 막아주며, 자로를 형성하여 수평코일에 의해 생긴 자계를 강화시켜주는 역할을 하는 것이다.In general, the ferrite core for deflection yoke is cylindrical, which is best if it is one-piece, but is made of ferrite core piece so that it is easy to wind the vertical coil and can be mounted on the outside of the coil separator, and the ferrite core piece is wound around the coil separator. After installation, it is fixed with a core clamp to prevent external leakage of magnetic fields generated from horizontal coils and vertical coils, and to form magnetic paths to reinforce magnetic fields generated by horizontal coils.
그런데 종래의 페라이트코어(21)는 제 3 도에 도시한 바와 같이 한쌍의 페라이트코어편(22) (22)을 형성하되, 분할면(23)이 매끄럽게 형설되어 코일쎄퍼레이터의 외측에 수직코일을 권선하여 취부시 수직코일이 권선된 페라이트코어편(22) (22)에 매끄럽게 형설된 분할면(23)이 화살표 방향으로 서로 어긋나게 되어 자기 저항이 증가로 인한 페라이트코어(1)의 효율이 저하되고 이로 인하여 자계의 충분한 자로를 형성하지 못하게 되는 문제점이 있었다.However, the conventional ferrite core 21 forms a pair of ferrite core pieces 22 and 22, as shown in FIG. 3, but the partition surface 23 is smoothly formed so that a vertical coil is formed outside the coil separator. When the windings are mounted, the divided surfaces 23 smoothly formed on the ferrite core pieces 22 and 22 on which the vertical coil is wound are shifted from each other in the direction of the arrow so that the efficiency of the ferrite core 1 is reduced due to the increase in the magnetic resistance. As a result, there was a problem that it is impossible to form a sufficient magnetic field of the magnetic field.
본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로서 편향요크용 페라이트코어의 분할면을 경사지게 암분할면과 숫분할면으로 형설하여 결합의 간편 용이함과 엇갈림을 방지하여 자계의 손실 및 페라이트코어 효율이 떨어짐을 줄일 수 있도록 하려는 것이 목적이다.The present invention was devised to solve such a conventional problem, and the dividing surface of the deflection yoke ferrite core is inclined to be divided into the dark dividing surface and the male dividing surface to prevent the loss of magnetic field and the ferrite core efficiency. The aim is to reduce this drop.
상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Referring to the present invention in detail based on the accompanying drawings that can achieve the above object is as follows.
제 1 도 및 제 2 도에 도시한 바와 같이 편향요크용 페라이트코어(1)에 있어서 한쪽의 페라이트코어(2) 분할면에 암분할면(3)을 형설하고 타측의 페라이트코어편(2') 분할면에는 숫분할면(3')을 형설하여 페라이트코어편(2) (2')의 엇갈림을 방지할 수 있도록 구성된 것이다.As shown in FIG. 1 and FIG. 2, in the ferrite core 1 for the deflection yoke, a female divided surface 3 is formed on one of the ferrite cores 2 divided surface, and the other ferrite core piece 2 'is formed. In the divided surface, a male split surface 3 'is formed to prevent the ferrite core pieces 2 and 2' from being staggered.
이와 같이 구성된 페라이트코어(1)는 코일쎄퍼레이터의 외측에 취부하되 페라이트코어편(2)의 분할면에 형설된 암분할면(3)에 타측의 페라이트코어편(2)의 분할면에 형설된 숫분할면(3')이 긴밀히 접촉되면서 결합되면 코어클램프로 고정하면 된다.The ferrite core 1 configured as described above is mounted on the split surface of the ferrite core piece 2 on the other side to the arm split surface 3 formed on the split surface of the ferrite core piece 2 while being mounted outside the coil separator. When the male split surface (3 ') is in close contact with each other, the core clamp may be fixed.
이상 설명한 바와 같이 경사지게 암분할면과, 숫분할면이 형설된 페라이트코어편이 간편 용이하게 긴밀히 접촉 결합되어 조립시 충격에도 엇갈림을 방지하므로서 작업 능률을 향상시키며 페라이트코어가 엇갈림없이 긴밀한 접촉으로 자기저항이 감소되어 페라이트 코어의 효율이 향상되고 이로 인하여 자계의 충분한 자로를 형성할 수 있는 유용한 고안이다.As described above, the ferrite core piece with the inclined arm dividing surface and the male dividing surface is easily and intimately contacted, thereby improving the work efficiency by preventing the displacement during the assembly and the magnetic resistance is increased by the intimate contact without the ferrite core being staggered. It is a useful design that can be reduced to improve the efficiency of the ferrite core and thereby form a sufficient magnetic path of the magnetic field.
