본 고안은 편향요크의 네크부 고정장치에 관한 것으로서, 더욱 상세하게는 편향요크를 CRT의 네크부에 설치한 상태에서 화면특성을 조정하기 위해 사방으로 유동시킬 때 편향요크의 네크부가 틀어지지 않도록한 편향요크의 네크부 고정장치에 관한 것이다.The present invention relates to a neck portion fixing device of the deflection yoke, and more particularly, the neck portion of the deflection yoke is not twisted when the deflection yoke is installed in the neck portion of the CRT to flow in all directions to adjust the screen characteristics. A neck fixing device of a deflection yoke.

일반적으로 편향요크(Deflection Yoke)는 CRT의 네크부에 설치되는 것으로서, 제1도에 도시된 바와 같이 수평편향코일(2)과 수직편향코일(3)의 조합으로 구성되며 서로 분리된 한쌍의 코일세퍼레이터(1) 내주면에 수평편향코일(2)이 설치된 다음 네크부(5)에 형성된 걸림턱(5b)과 걸림홈(5a)에 의해 한쌍의 코일세퍼레이터(1)가 서로 결합된다. 또한 결합된 상태에서 이의 외주면에 수직편향코일(3)이 설치되고 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 coils separated from each other. After the horizontal deflection coil 2 is installed on the inner circumferential surface of the separator 1, a pair of coil separators 1 are coupled to each other by a locking jaw 5b and a locking groove 5a formed in the neck portion 5. In addition, a vertical deflection coil 3 is installed on the outer circumferential surface thereof in a coupled state, and 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 전자총에서 발사된 전자빔을 좌, 우측 및 상, 하측 방향으로 편향시켜 CRT의 형광면 상에 형성된 RGB에 충돌시키는 역할을 한다. 그러나 종래에는 CRT의 네크부에 편향요크의 네크부(5)를 고정 설치한 다음 이의 화면특성을 조정하기 위해 사방으로 유동시키는 과정에서 네크부(5)가 비틀려짐으로 화면조정이 어렵게 되는 문제점이 있다. 즉 네크부(5)는 걸림턱(5b)과 걸림홈(5a)이 단순히 결합된 상태임으로 결합력은 강한 반면에 비틀림응력이 약한 단점이 발생된다.The deflection yoke configured as described above deflects the electron beam emitted from the electron gun of the CRT in left, right, up and down directions to collide with the RGB formed on the fluorescent surface of the CRT. However, conventionally, the neck portion 5 of the deflection yoke is fixedly installed in the neck portion of the CRT, and then the neck portion 5 is twisted in the process of flowing in all directions to adjust the screen characteristics thereof. There is this. That is, the neck portion 5 has a disadvantage in that the coupling force is strong while the torsion stress is weak because the locking jaw 5b and the locking groove 5a are simply coupled.

본 고안은 종래의 문제점을 해결하기 위해 안출한 것으로서 본 고안의 목적은 서로 분리된 코일세퍼레이터의 서로 대응되는 네크부에 비틀림응력을 갖는 지지수단을 형성함으로서 네크부의 틀어짐이 방지되도록한 변향요크의 네크부 고정장치를 제공함에 있다.The present invention devised to solve the conventional problems, the object of the present invention is to form a support means having a torsion stress in the neck portion corresponding to each other of the coil separator separated from each other by the neck of the deflection yoke to prevent the neck portion from twisting In providing a secondary fixing device.
