이 고안은 편향요크의 수평편향요코일의 유동방지 구조에 관한 것으로서, 더욱 상세하게는 수평편향코일의 네크부측 접촉면을 수직한 경사면을 갖는 금형틀로 압착 성형한 후, 코일세퍼레이터에 장착시킴으로써 편향요크의 그린빔 특성을 효과적으로 조정할 수 있는 수평편향코일의 유동방지 구조에 관한 것이다.The present invention relates to a flow preventing structure of a horizontal deflection yoke coil of a deflection yoke. More specifically, the neck-side contact surface of a horizontal deflection coil is press-molded into a mold having a vertically inclined surface, and then mounted on a coil separator. The present invention relates to a flow preventing structure of a horizontal deflection coil, which can effectively adjust the green beam characteristics of a.

일반적으로 텔레비젼 수상기나 모니터의 음극선관(CRT)에서는 전자총에서 주사되는 적색(R), 녹색(G) 및 청색(B)의 전자빔을 편향시키는 편향요크가 장착되어서 일정한 방식으로 주사되는 전자빔을 편향시켜서 화면을 형성한다. 상기 편향요크에는 여러가지 타입의 수직편향코일과 수평편향코일을 코일세퍼레이터의 내주면 또는 외주면에 장착하게 되는데, 예를들면, 수평편향코일의 성형모향에 따라 그린빔의 특성이 달라진다.In general, a cathode ray tube (CRT) of a television receiver or a monitor is equipped with a deflection yoke for deflecting red (R), green (G), and blue (B) electron beams scanned by an electron gun. Form the screen. In the deflection yoke, various types of vertical deflection coils and horizontal deflection coils are mounted on the inner circumferential surface or the outer circumferential surface of the coil separator. For example, the characteristics of the green beam vary according to the molding orientation of the horizontal deflection coil.

종래의 수평편향코일(11)은 제1도에 나타낸 바와 같이, 소정모양의 금형틀로 성형함으로써 접촉면(13)이 형성되며, 특히, 네크부측의 장착면을 일자형의 금형틀(100)로 눌러줌으로써 압착면(12)이 형성된다. 이러한 형태의 수평편향코일(11)은 코일세퍼레이터에 장착되는데, 상기 압착면(12)의 성형 정도에 따라 그린빔의 특성이 조정된다.In the conventional horizontal deflection coil 11, as shown in FIG. 1, the contact surface 13 is formed by molding into a mold of a predetermined shape, and in particular, the mounting surface on the neck portion is pressed by a straight mold 100. By pressing, the pressing surface 12 is formed. The horizontal deflection coil 11 of this type is mounted on the coil separator, and the characteristics of the green beam are adjusted according to the degree of shaping of the pressing surface 12.

그러나, 이러한 종래의 수평편향코일(11)은 접촉면(13)이 밋밋하게 성형되어 있기때문에, 코일세퍼레이터에 장착된후 다음의 연속공정에서 유동이 발생되므로 그린빔의 특성이 흐트러지게 되는 문제점이 있다.However, the conventional horizontal deflection coil 11 has a problem that the characteristics of the green beam are disturbed because the contact surface 13 is formed in a flat shape, so that the flow is generated in the subsequent continuous process after being mounted on the coil separator. .

따라서 이 고안은 상기와 같은 단점을 해결하기 위한 것으로서, 이 이 고안의 목적은 수평편향코일의 접촉면 상단을 소정 모양의 금형틀로 압착 성형하여 압착면을 만들어 줌으로써 코일세퍼레이터에 장착시 유동을 방지함과 동시에 그린빔의 특성을 효과적으로 조정할 수 있는 수평편향코일의 유동방지 구조를 제공함에 있다.Therefore, this invention is intended to solve the above disadvantages, the object of this invention is to form a pressing surface by pressing the top of the contact surface of the horizontal deflection coil into a mold of a predetermined shape to prevent flow when mounted on the coil separator. At the same time to provide a flow preventing structure of the horizontal deflection coil that can effectively adjust the characteristics of the green beam.

상기와 같은 목적을 달성하기 위한 이 고안에 따른 수평편향코일의 유동방지 구조의 특징은 소정 모양으로 압착 성형된 한쌍의 수평편향코일의 코일세퍼레이터에 장착되어 있는 편향요크에 있어서 ; 상기 수평편향코일의 압착면이 코일세퍼레이터의 돌기부에 걸쳐지도록 상기 압착면을 소정 모양의 금형틀로 압착하여 성형시킨 점에 있다.A characteristic of the flow preventing structure of the horizontal deflection coil according to the present invention for achieving the above object is a deflection yoke mounted on a coil separator of a pair of horizontal deflection coils press-molded into a predetermined shape; The pressing surface of the horizontal deflection coil is formed by pressing the pressing surface with a mold having a predetermined shape so that the pressing surface of the horizontal separator coil extends.

이하, 이 고안에 따른 수평편향코일의 유동방지 구조의 바람직한 하나의 실시예에 대하여 첨부 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of the flow preventing structure of the horizontal deflection coil according to the present invention will be described in detail with reference to the accompanying drawings.

제2도는 이 고안에 따른 수평편향코일과 금형틀을 나타낸 도면이다.2 is a view showing a horizontal deflection coil and a mold according to the present invention.

먼저, 제2도에 도시된 바와 같이, 코일권선기에 의해 소정 모양으로 권선된 후 성형된 수평편향코일(21)과 소정 모양의 금형틀(200)을 준비한다.First, as shown in FIG. 2, a horizontal deflection coil 21 and a mold die 200 having a predetermined shape are prepared after winding in a predetermined shape by a coil winding machine.

다음, 상기 금형틀(200)로 수평편향코일(21)의 접촉면(23)의 상단을 압착시켜서 수직으로 경사진 압착면(22)을 형성시킨다.Next, the upper end of the contact surface 23 of the horizontal deflection coil 21 with the mold frame 200 is pressed to form a vertically inclined pressing surface 22.

상기와 같이 성형된 수평편향코일(21)은 제3도에 도시된 바와 같이 코일세퍼레이터(30)에 장착되어 진다. 상기 코일세퍼레이터(30)는 네크부(31), 중앙부(33) 및 스크린부(32)로 구성되어 있으며, 중앙부(33)의 상단에 2쌍의 돌기(34)(34a)가 형성되어 진다.The horizontal deflection coil 21 formed as described above is mounted to the coil separator 30 as shown in FIG. The coil separator 30 is composed of a neck portion 31, a center portion 33, and a screen portion 32, and two pairs of protrusions 34 and 34a are formed at an upper end of the center portion 33.

따라서, 수평편향코일(21)의 접촉면(23) 상단의 압착면(22)이 코일세퍼레이터(30)의 돌기부(34)(34a)를 감싸안아 걸쳐지도록 함으로써, 장착된 수평편향코일(21)의 유동 현상을 효과적으로 방지함과 동시에 그린빔의 특성을 흐트러뜨리지 않는다.Therefore, the pressing surface 22 of the upper end of the contact surface 23 of the horizontal deflection coil 21 is wrapped around the protrusions 34 and 34a of the coil separator 30, thereby to prevent the mounting of the horizontal deflection coil 21. It effectively prevents the flow phenomenon and does not disturb the characteristics of the green beam.

상기한 바와 같이, 이 고안에 따른 수평편향코일의 유동방지 구조에 의하면, 소정 모양으로 압착 성형된 한쌍의 수평편향코일이 코일세퍼레이터에 장착되어 있는 편향요크에 있어서 ; 상기 수평편향코일의 압착면이 코일세퍼레이터의 돌기부에 걸쳐지도록 상기 압착면을 소정 모양의 금형틀로 압착하여 성형시킴으로써 이후의 연속 공정에서 수평편향코일의 유동을 방지한다.As described above, according to the flow preventing structure of the horizontal deflection coil according to the present invention, in a deflection yoke in which a pair of horizontal deflection coils press-molded into a predetermined shape is mounted on the coil separator; The pressing surface of the horizontal deflection coil is pressed and molded into a mold having a predetermined shape so that the pressing surface of the horizontal separator coil is prevented from flowing in the subsequent deflection coil.

따라서 이 고안에 따른 수평편향코일의 유동방지 구조는, 수평편향코일의 접촉면 상단을 소정 모양의 금형틀로 압착 성형하여 압착면을 만들어 줌으로써 코일세퍼레이터에 장착시 유동을 방지함과 동시에 그린빔의 특성을 효과적으로 조정할 수 있는 이점이 있다.Therefore, the flow preventing structure of the horizontal deflection coil according to the present invention, by forming the pressing surface by pressing the upper end of the contact surface of the horizontal deflection coil into a mold of a predetermined shape to prevent the flow when mounted on the coil separator and at the same time the characteristics of the green beam There is an advantage that can be adjusted effectively.
