Description

편향요크{Deflection yoke}Deflection yoke

본 발명은 편향요크(deflection yoke)에 관한 것으로서, 보다 상세하게는 틸팅 코일에 과전류가 인가되는 것을 방지하는 캐피시티의 지지구조를 개선한 편향요크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deflection yoke, and more particularly, to a deflection yoke having an improved capacity support structure for preventing overcurrent from being applied to a tilting coil.

일반적으로 TV수상기 또는 모니터의 음극선관(CRT)에 사용되는 편향요크는 새들-트로이달(saddle toroidal type), 새들-새들형등 여러 가지 형태로 되어 있다.In general, the deflection yoke used in a cathode ray tube (CRT) of a TV receiver or a monitor has various forms such as a saddle toroidal type and a saddle-saddle type.

이러한 편향요크는 도 1에 나타내 보인 바와 같이, 좌,우 대칭형으로 되어 하나로 합체되는 한쌍의 코일 세퍼레이터(10)을 구비한다.As shown in FIG. 1, the deflection yoke has a pair of coil separators 10 which are symmetrical in left and are integrated into one.

코일 세퍼레이터(10)는, 음극선관(1)의 스크린면(1a)에 결합되는 스크린부(11)와, 리어 커버(rear cover;12) 및 이 리어 커버(12)의 중심면으로부터 일체로 연장 형성되어 음극선관(1)의 전자총부(1b)에 결합되는 네크부(13)로 이루어진다.The coil separator 10 extends integrally from the screen portion 11 coupled to the screen surface 1a of the cathode ray tube 1, the rear cover 12 and the center surface of the rear cover 12. It is formed of a neck portion 13 which is formed and coupled to the electron gun portion 1b of the cathode ray tube 1.

코일 세퍼레이터(10)의 내,외주면에는 수평편향자계와 수직 편향자계를 형성하기 위한 수평편향코일(14)과 수직편향코일(15)이 각각 마련된다.The inner and outer circumferential surfaces of the coil separator 10 are provided with a horizontal deflection coil 14 and a vertical deflection coil 15 for forming a horizontal deflection magnetic field and a vertical deflection magnetic field, respectively.

그리고 수직편향코일(15)을 감싸도록 마련되어 수직자계를 강화시키기 위한 페라이트코어(16)가 마련된다.The ferrite core 16 is provided to surround the vertical deflection coil 15 to reinforce the vertical magnetic field.

한편, 코일 세퍼레이터(10)의 스크린부(11)에는 도 2에 나타내 보인 바와 같이, 전자빔의 편향과정에서 화면상에서 발생되는 틸팅상태를 보정하기 위한 틸팅코일(21)이 외주면에 권선된 코일 캡(20)이 복수의 훅크편(22)을 통해 결합된다.On the other hand, as shown in Figure 2, the coil portion 10 of the coil separator 10, the coil cap wound around the outer circumferential surface of the coiling coil 21 for correcting the tilting state generated on the screen during the deflection process of the electron beam ( 20) is coupled through a plurality of hook pieces 22.

따라서 코일 캡(20)상의 틸팅코일(21)에 전류를 인가하는 것에 따라 적절하게 화면상에서의 수직변형을 보상하게 되는 것이다.Therefore, as the current is applied to the tilting coil 21 on the coil cap 20, the vertical deformation on the screen is appropriately compensated.

그러나 이러한 종래 편향요크에 있어서는, 코일 캡(20)이 단지 훅크편(22)을통해 코일 세퍼레이터(10)의 스크린부(11)에 결합되어 있는 것이기 때문에 외부 충격등에 의해 쉽게 유동되어 안정된 화면 보상을 행할 수 없는 문제점이 야기된다.However, in such a conventional deflection yoke, since the coil cap 20 is simply coupled to the screen portion 11 of the coil separator 10 through the hook piece 22, it is easily flowed by an external impact or the like to provide stable screen compensation. A problem that cannot be done is caused.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 코일 캡의 유동을 방지하여 화면상의 수직보상을 안정되게 행할 수 있는 편향요크를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, and an object thereof is to provide a deflection yoke capable of stably performing vertical compensation on a screen by preventing the flow of the coil cap.

도 2는 종래 편향요크에 있어서, 코일캡과 코일 세퍼레이터간의 결합 상태를 발췌하여 나타낸 사시도,Figure 2 is a perspective view showing an extract of the coupling state between the coil cap and the coil separator in the conventional deflection yoke,

먼저 도 1을 참조하면, 좌,우 대칭형으로 되어 하나로 합체되는 한쌍의 코일 세퍼레이터(10)을 구비한다.First, referring to FIG. 1, a pair of coil separators 10, which are symmetrical left and right, are merged into one.

코일 세퍼레이터(10)는, 음극선관(1)의 스크린면(1a)에 결합되는 스크린부(11)와, 리어 커버(rear cover;12) 및 이 리어 커버(12)의 중심면으로부터 일체로 연장 형성되어 음극선관(1)의 전자총부(1b)에 결합되는 네크부(13)로 이루어진다.The coil separator 10 extends integrally from the screen portion 11 coupled to the screen surface 1a of the cathode ray tube 1, the rear cover 12 and the center surface of the rear cover 12. It is formed of a neck portion 13 which is formed and coupled to the electron gun portion 1b of the cathode ray tube 1.
