본 고안은 편향요크의 페라이트코어 고정구조에 관한 것으로서, 특히, 텔레비젼이나 모니터등에 사용되는 편향요크에 있어서 수직편향코일이 감겨진 페라이트코어를 코일세퍼레이터에 조립시킬때 페라이트코어가 유동됨이 없이 견고하게 고정되도록 한 페라이트코어의 고정구조에 관한 것이다.The present invention relates to a ferrite core fixing structure of a deflection yoke, and in particular, in a deflection yoke used for a television or a monitor, a ferrite core wound with a vertical deflection coil is rigidly assembled without being flown when assembled to a coil separator. It relates to a fixed structure of the ferrite core to be fixed.
일반적으로, TV브라운관이나 모니터등의 음극선관(CRT)에는 편향요크를 장착하여 전자총에서 방사되는 전자빔의 위치를 결정해 주게 되는 것으로서, 일반적인 편향요크의 구조는 제1도에 나타낸 바와같이 편향요크(1)의 코일세레퍼레이터(2) 내, 외측에 수평편향코일(3)과 수직편향코일(4)이 감겨진 페라이트코어(5)가 각각 고정 클램프(6)에 의해 고정되어 음극선관에 장착되어 진다.Generally, a deflection yoke is mounted on a cathode ray tube (CRT) such as a TV brown tube or a monitor to determine the position of an electron beam emitted from an electron gun. The structure of a general deflection yoke is shown in FIG. The ferrite core 5, in which the horizontal deflection coil 3 and the vertical deflection coil 4 are wound inside and outside the coil separator 2 of 1), is fixed by the clamp 6 to be mounted on the cathode ray tube. It is done.
이와같이 구성된 편향요크(1)는, 수평 및 수직편향코일(3), (4)에 톱니파 펄스가 인가됨에 따라 자계가 발생되어 전자총에서 방사되는 전자빔의 위치를 결정해 주게 되는 것이다.In the deflection yoke 1 configured as described above, as the sawtooth pulse is applied to the horizontal and vertical deflection coils 3 and 4, a magnetic field is generated to determine the position of the electron beam emitted from the electron gun.
한편, 상기 편향요크(1)의 코일세퍼레이터(2) 외측면에 수직편향코일(4)이 감겨진 페라이트코어(5)를 조립시키는 경우 코일세퍼레이터(2)의 상하부에 형성된 코어지지대(7), (7′)사이에 코어(5)를 끼워 고정시킬때, 코일세퍼레이터(2)와 코어(5)사이에 두꺼운 웨지(wedge)를 끼워 코어(5)의 유동을 방지할 수 있도록 하고 있다.On the other hand, when assembling the ferrite core (5) wound vertical coil 4 on the outer surface of the coil separator (2) of the deflection yoke (1) core support (7) formed on the upper and lower parts of the coil separator (2), When the core 5 is sandwiched and fixed between 7 ', a thick wedge is sandwiched between the coil separator 2 and the core 5 to prevent the flow of the core 5.
그러나, 이와같은 코어(5)를 양쪽에서만 지지하게 되므로 코어(5)를 견고하게 고정시키는데 적합하지 못하여 좌우불균형이 발생하게 되고, 페라이트코어(5)가 편심되거나 유동되는 현상이 발생하여 화면불량을 야기시키는 결점이 있으며, 편향요크의 크로스토크(CROSS TALK)조정시에도 불균형이 발생된다는 문제점이 있는 것이다.However, since the core 5 is supported only at both sides, it is not suitable for firmly fixing the core 5, resulting in left and right imbalance, and a phenomenon in which the ferrite core 5 is eccentric or flows, resulting in screen defects. There is a drawback that causes, and there is a problem that an imbalance occurs even when the cross-talk (CROSS TALK) adjustment of the deflection yoke.
본 고안은 상기와 같은 종래의 결점을 해결하기 위한 것으로서, 본 고안의 목적은 코일세퍼레이터의 외측에 상하로 돌기부를 형성하고, 상기 돌기부 사이의 아래쪽에 웨지가 장착되는 단차부를 형성하여 페라이트 코어를 조립시킬 수 있게 함으로써, 코어를 더욱 정밀하게 고정함과 동시에 유동을 방지하여 화면 불량을 최소화 할수 있는 편향요크의 페라이트코어 고정구조를 제공하는데 있다.The present invention is to solve the conventional drawbacks as described above, the object of the present invention is to form a projection up and down on the outer side of the coil separator, and to form a stepped portion to the wedge is mounted between the projections to assemble the ferrite core It is possible to provide a ferrite core fixing structure of a deflection yoke that can fix the core more precisely and prevent flow, thereby minimizing screen defects.
상기의 목적을 달성하기 위한 본 고안의 특징은, 편향요크의 코일세퍼레이터 외주면에 수직편향코일이 감겨진 페라이트코어를 조립시킴에 있어서, 상기 코일세퍼레이터의 외주면에 상하로 돌기부를 형성하고, 상기 돌기부 사이의 아래쪽에는 다수의 요홈이 형성되도록 단차를 형성하여 웨지를 장착하고, 상기 돌기부와 웨지면에 상기 돌기부와 웨지면에 페라이트코어를 고정시킬 수 있게한 것에 있다.A feature of the present invention for achieving the above object is, in assembling a ferrite core wound with a vertical deflection coil on the outer peripheral surface of the coil separator of the deflection yoke, to form a projection up and down on the outer peripheral surface of the coil separator, between the protrusions The lower portion of the wedge is formed so that a plurality of grooves are formed, the wedge is mounted, and the ferrite core can be fixed to the protrusion and the wedge surface on the protrusion and the wedge surface.
이하, 본 고안의 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail according to the accompanying drawings.
제2a, 2b도에 나타낸 바와같이 본고안의 편향요크(1)에 있어서, 코일세퍼레이터(2)의 외주면 상하단부에 돌기부(8), (8′)가 일정길이로 형성되어 있고, 상기 돌기부(8), (8′)의 외측에는 코어지지대(7), (7′)가 형성되어 있다.As shown in Figs. 2A and 2B, in the deflection yoke 1 of the present invention, projections 8 and 8 'are formed at constant lengths at upper and lower ends of the outer circumferential surface of the coil separator 2, and the projections 8 ), The core supports 7 and 7 'are formed outside the 8'.
따라서, 상기 돌기부(8), (8′)와 코어지지대(7), (7′)에 의해 수직편향코일(4)이 감겨진 페라이트코어(5)의 조립시에 상하, 좌우의 유동을 방지할 수 있으며, 또한 편향요크(1)의 크로스토크 조정시 수직편향코일(4)을 미세 회전시킬때에 발생할 수 있는 불균형을 방지할 수 있다.Therefore, it prevents the up, down, left and right flow during assembly of the ferrite core 5 in which the vertical deflection coil 4 is wound by the protrusions 8, 8 'and the core supports 7, 7'. In addition, it is possible to prevent an imbalance that may occur when the vertical deflection coil (4) is finely rotated during the crosstalk adjustment of the deflection yoke (1).
한편, 상기 코일세퍼레이터(2)에 형성된 돌기부(8), (8′)들 사이의 아래쪽에는 제2c도에 나타낸 바와 같이 요홈(9)이 형성된 다수의 단차부(10)가 형성되어 있고, 이 단차부(10)의 외측면에 탄성체 재질의 웨지(11)가 부착되어 있다.On the other hand, a plurality of stepped portions 10 having grooves 9 are formed on the lower side between the projections 8 and 8 'formed in the coil separator 2, as shown in FIG. 2C. An elastic wedge 11 is attached to the outer surface of the stepped portion 10.
따라서, 수직편향코일(4)이 감겨진 페라이트코어(5)를 조립시킬때, 상기 웨지(11)가 단차부(10)의 요홈(9)들 사이로 눌러 들어가게 되므로 더욱 유동을 방지할 수 있으며, 부착강도가 높아지게 된다.Therefore, when assembling the ferrite core 5 wound around the vertical deflection coil 4, the wedge 11 is pressed into the grooves 9 of the stepped portion 10, thereby preventing further flow. The adhesion strength becomes high.
이때, 상기 코일세퍼레이터(2)의 외측면은 3차원 곡선이기 때문에 웨지(11)의 두께가 두꺼울수록 복원력에 의해 접착력이 약해지므로 웨지(11)를 얇게 하는 것일 바람직하며, 크로스토크 조정시에도 코어(5)가 밀리는 현상을 최소화할 수가 있다.At this time, since the outer surface of the coil separator 2 is a three-dimensional curve, the thicker the wedge 11 is, the weaker the adhesive force is due to the restoring force, so that the wedge 11 is thinner. (5) push can be minimized.
