본 고안은 편향요크에 장착되는 마그네트 취부 구조에 관한 것으로서, 특히, 대형 광각 편향요크에 있어서의 화면의 찌그러짐(distorrion)악화 방지를 보정하기 위하여 코일 세퍼레이터의 스크린부에 장착되는 마그네트 취부구조에 관한 것이다.The present invention relates to a magnet mounting structure mounted on a deflection yoke, and more particularly, to a magnet mounting structure mounted on a screen portion of a coil separator in order to compensate for the prevention of distortion of a screen in a large wide-angle deflection yoke. .
일반적으로, 편향요크의 코일 세퍼레이터에 장착된 수직 및 수평 편향코일에 톱니파 펄스가 인가되면 자계가 발생되어 전자총으로부터 방사되는 전자빔이 음극선관의 기구적인 메카니즘에 의한 오차와 편향요크 자체의 오차에 의해 중심위치에 정확하게 주사되지 않기 때문에 그 보정수단으로서 마그네트를 장착하여 사용하고 있다.In general, when a sawtooth pulse is applied to the vertical and horizontal deflection coils mounted on the coil separator of the deflection yoke, a magnetic field is generated and the electron beam radiated from the electron gun is centered by the error due to the mechanical mechanism of the cathode ray tube and the error of the deflection yoke itself. Since the magnet is not accurately scanned at the position, a magnet is used as the correction means.
종래에 이와같은 편향요크의 코일 세퍼레이터에 마그네트를 취부고정함에 있어서는 제3도에 나타낸 바와같이 마그네트의 상면에 접착제등을 바른후에 코일 세퍼레이터 하단 스크린부의 내측에 끼워 장착하고 있다.Conventionally, in attaching and fixing a magnet to a coil separator of such a deflection yoke, as shown in Fig. 3, after applying an adhesive or the like to the upper surface of the magnet, it is mounted inside the coil separator lower screen portion.
그러나, 접착제 도포시 마그네트의 유동으로 인한 뒤틀림이 발생하여 화면의 찌그러짐이 악화됨으로 작업시에 주의해야 하며, 마그네트의 취부구조가 코일 세퍼레이터 내면에 장착되는 구조이므로 코일세퍼레이터의 변형으로 인하여 마그네트를 취부하기가 곤란하다는 문제점이 있었다.However, when the adhesive is applied, warpage occurs due to the flow of the magnet, so that the distortion of the screen deteriorates, and care must be taken during the work.As the mounting structure of the magnet is mounted on the inner surface of the coil separator, the magnet is attached due to the deformation of the coil separator. There was a problem that is difficult.
본 고안은 상기와 같은 문제점을 감안하여 이루어진 것으로서, 본 고안의 목적은 코일 세퍼레이터의 스크린부에 형성된 마그네트 홀더에 마그네트를 견고하게 고정시킬 수 있는 구조로 함으로써, 마그네트 고정시 틀어지는 일이 없이 안정되게 고정하여 화면 특성을 안정화 시킴과 동시에 작업성을 향상시킬 수 있게 함에 있다.The present invention has been made in view of the above problems, and an object of the present invention is to provide a structure that can firmly fix the magnet to the magnet holder formed on the screen portion of the coil separator, thereby stably fixing the magnet without being twisted. This stabilizes the screen characteristics and improves workability.
상기와 같은 목적을 달성하기 위한 본 고안의 특징은, 편향요크의 코일 세퍼레이터 하단부에 형성된 마그네트 홀더에 마그네틀 장착시킴에 있어서, 상기 마그네트 홀더의 측벽에 절결홈을 상하로 형성하고, 끝단에 걸림돌기가 형성된 탄성편을 각각 형성하여 마그네트를 탄력있게 고정 설치되게 한 것이 있다.Features of the present invention for achieving the above object, in the magnet mounting to the magnet holder formed on the lower end of the coil separator of the deflection yoke, forming a notch groove up and down on the side wall of the magnet holder, the locking projection at the end Each formed elastic piece is formed so that the magnet is fixedly installed.
이하, 본 고안의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 마그네트 홀더(7)가 부착된 상태의 편향요크(1)의 전체사시도를 나타낸 도면으로서, 편향요크(1)를 구성하는 코일 세퍼레이터(2)내부에는 한쌍의 수평편향코일(3)이 권선되어 내장되고, 외부에는 페라이트코어(5)에 권선된 수직편향코일(4)이 코어 클램프(6)에 의하여 고정된다.FIG. 1 is a view showing an overall perspective view of the deflection yoke 1 with the magnet holder 7 of the present invention attached thereto, and a pair of horizontal deflection coils inside the coil separator 2 constituting the deflection yoke 1. 3) is wound and built-in, the vertical deflection coil 4 wound on the ferrite core (5) is fixed by the core clamp (6).
또한, 코일 세퍼레이터(2)의 상단의 네크부에는 전자총이 삽입되는 삽입구가 형성되며, 상기 삽입구에는 절결홈이 주위에 형성되어 탄성력을 갖게 된다.In addition, an insertion hole into which an electron gun is inserted is formed in the neck portion of the upper end of the coil separator 2, and a notch groove is formed around the insertion hole to have elastic force.
한편 제2a, b도에서와 같이 편향요크(1) 코일 세퍼레이터(2) 하단부의 스크린부에는 마그네트 홀더(7)가 장착되는데 이 마그네트 홀더(7)는 측벽에 상하로 절결홈(11), (11′)을 형성하여 마그네트(12)를 고정지지해 주는 지지대(8), (8′)가 상하로 형성되어 있고, 양측으로는 마그네트(12)를 삽입할때 텐션(tension)작용을 주기위해 끝단에 걸림돌기(9),(9′)가 각 형성된 탄성편(10), (10′)을 형성하여 탄성력 있게 양측에서 마그네트(12)를 지지할 수 있게 된다.Meanwhile, as shown in FIGS. 2A and 2B, the magnet holder 7 is mounted on the screen of the lower end of the deflection yoke coil separator 2, and the magnet holder 7 is notched up and down on the side wall. 11 ') to support the magnets 12 and the support (8, 8') is formed up and down, both sides to give a tension (tension) action when inserting the magnet (12) The engaging protrusions 9 and 9 'are formed at the ends to form the formed elastic pieces 10 and 10', respectively, so that the magnets 12 can be supported on both sides with elastic force.
이상에서와 같이 본 고안은, 코일 세퍼레이터(2) 하단부에 형성된 마그네트 홀더(7)에 삽입 고정되는 마그네트(12)를 유동없이 견고하게 고정시킬 수 있게 함으로써, 작업을 용이하게 하여 생산성을 향상시키고, 화면 특성을 더욱 안정화 시킬수 있는 것이다.As described above, the present invention makes it possible to securely fix the magnet 12 inserted into the magnet holder 7 formed at the lower end of the coil separator 2 without flow, thereby facilitating the work to improve productivity, You can further stabilize the screen characteristics.
