본 고안은 음극선관용 편향요오크에 관한 것으로, 더 상세하게는 음극선관의 네크부와 고정되는 고정부가 개량된 음극선관용 편향요오크에 관한 것이다.The present invention relates to a deflection yoke for a cathode ray tube, and more particularly to a deflection yoke for a cathode ray tube having a fixed portion fixed to the neck portion of the cathode ray tube.

통상적으로 음극선관은 제1도에 나타내 보인바와 같이 그 내면에 형광막이 형성된 패널(10)과, 이 패널(10)과 봉착되는 것으로 그 네크부(21)의 내부와 콘부(22)에 전자총(30)과 편향요오크(40)가 설치된 펀넬(20)을 구비하여 구성된 것으로, 상기 전자총(30)으로부터 방출된 전자빔이 편향요오크(40)에 의해 형광막의 주사위치에 따라 선택적으로 편향되어 형광막에 랜딩됨으로써 화상을 형성하게 된다.In general, as shown in FIG. 1, the cathode ray tube is sealed with a panel 10 having a fluorescent film formed on its inner surface, and is sealed to the panel 10. An electron gun is formed inside the neck portion 21 and the cone portion 22. 30) and a funnel 20 provided with the deflection yoke 40, the electron beam emitted from the electron gun 30 is selectively deflected by the deflection yoke 40 in accordance with the dice of the fluorescent film to fluoresce Landing on the film forms an image.

따라서 보다 선명한 화상을 형성하기 위해서는 상기 전자총(30)으로부터 방출된 전자빔이 형광막에 정확하게 랜딩되어야 하므로 전자빔을 편향시키는 편향요오크(40)는 음극선관의 네크부에 정확하게 장작되어야 한다.Therefore, in order to form a clearer image, the electron beam emitted from the electron gun 30 must be accurately landed on the fluorescent film, so that the deflection yoke 40 for deflecting the electron beam must be accurately mounted on the neck portion of the cathode ray tube.

제2도에는 편향요오크의 고정부가 음극선관의 네크부에 고정된 상태를 나타내 보였다.2 shows a state in which the fixing portion of the deflection yoke is fixed to the neck portion of the cathode ray tube.

이것은 편향요오크(40)의 세퍼레이터(41) 상단에 형성되며 그 길이 방향으로 소정길이 절제된 원통형의 고정부(42)에 테이프(45)가 감기 음극선관의 네크부(21)을 삽입하고 클램프(46)를 이용하여 상기 고정부(42)를 네크부(21)에 고정하여 왔다.It is formed on the upper side of the separator 41 of the deflection yoke 40 and the neck 45 of the cathode ray tube wound by the tape 45 is inserted into the cylindrical fixing part 42 cut in a predetermined length in the longitudinal direction, and the clamp ( The fixing part 42 has been fixed to the neck part 21 using 46).

상기와 같이 음극선관의 네크부(21)에 편향요오크(40)의 고정부(42)를 고정하는 것은 고정부(42)의 내주면과 네크부(21)의 외주면 사이의 미끄럼을 방지하기 위하여 테이프(45)를 감아야 하므로 이에 따른 많은 작업공수가 소요되게 되고 별도로 테이프(45)를 마련하여야 하므로 생산원가가 상승하게 되는 문제점이 있었다.As described above, fixing the fixing portion 42 of the deflection yoke 40 to the neck portion 21 of the cathode ray tube is to prevent slippage between the inner circumferential surface of the fixing portion 42 and the outer circumferential surface of the neck portion 21. Since the tape 45 has to be wound, a lot of work is required accordingly, and since the tape 45 must be prepared separately, the production cost increases.

본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로, 음극선관의 네크부와 그 고정부의 결합에 따른 결합력을 향상시킬 수 있으며, 나아가서는 이들의 결합에 따른 작업공수를 줄여 생산성의 향상을 도모할 수 있는 음극선관용 편향요오크를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, it is possible to improve the bonding force according to the combination of the neck portion and the fixing portion of the cathode ray tube, and furthermore, it is possible to improve the productivity by reducing the labor of the combination It is an object of the present invention to provide a deflection yoke for a cathode ray tube.

상기 목적을 달성하기 위하여 본 고안은,The present invention to achieve the above object,

그 단부에 복수개의 절개편이 원통형으로 배열되어 이루어진 고정부를 가지는 세퍼레이터와, 세퍼레이터에 고정되는 편향코일을 구비하여 된 음극선관용 편향요오크에 있어서,A deflection yoke for cathode ray tubes, comprising: a separator having a fixing portion having a plurality of cut pieces arranged in a cylindrical shape at an end thereof; and a deflection coil fixed to the separator.

상기 고정부를 이루는 절개편의 내면에 흡착부가 마련된 것을 그 특징으로 한다.It is characterized in that the adsorption portion is provided on the inner surface of the cut piece forming the fixing portion.

본 고안에 있어서, 상기 흡착부는 상기 절개편의 내주면에 내면으로 부터 소정길이 돌출된 평활면의 중앙에 점차적으로 인입되는 홈이 형성된 것을 그 특징으로 한다.In the present invention, the adsorption portion is characterized in that the groove is gradually drawn in the center of the smooth surface protruding a predetermined length from the inner surface on the inner peripheral surface of the cut piece.

이하 첨부된 보면을 참조하여 본 고안에 따른 한 바람직 한 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 음극선관용 편향요오크는 제3도에 나타내 보인바와 같이 그 상단에 음극선관의 네크부(21)와 결합되는 고정부(101)가 마련된 세퍼레이터(102)와 세퍼레이터(102)의 외주면에 설치된 페라이트 코어(103)와, 페라이트 코어(103)와 세퍼레이터(102)의 내주면에 고정 설치된 수직 수평 편향코일을 구비하여 구성된다. 여기에서 상기 세퍼레이터(102)의 상단에 형성된 고정부(101)는 복수개의 절개편 (101a)이 원통형을 이룰 수 있도록 배열설치되고 이 절개편(101a)의 내주면에는 본 고안에의 특징에 따라 흡착부(101b)가 형성되는데, 이 흡착부(101b)는 절개편(101a)으로부터 소정길이 돌출된 평활면(101c)에 이로부터 소정깊이 인입된 인입홈( 101d)을 형성하여 된 것이다. 상기 흡착부(101b)는 음극선관 네크부(21)의 외주면과의 밀착력을 향상시키기 위하여 연질의 소재를 이용하여 제작함이 바람직하다. 미설명부호 200은 클램프이다.The deflection yoke for the cathode ray tube according to the present invention is the outer peripheral surface of the separator 102 and the separator 102 provided with a fixing portion 101 coupled to the neck portion 21 of the cathode ray tube as shown in FIG. And a vertical horizontal deflection coil fixed to the inner circumferential surfaces of the ferrite core 103 and the separator 102. Here, the fixing part 101 formed on the top of the separator 102 is arranged so that a plurality of cut pieces 101a can be formed in a cylindrical shape, and the inner peripheral surface of the cut pieces 101a is adsorbed according to the characteristics of the present invention. The part 101b is formed, and this adsorption part 101b forms the inlet groove 101d which penetrates predetermined depth from the smooth surface 101c which protruded the predetermined length from the cut-out piece 101a. The adsorption portion 101b is preferably manufactured using a soft material to improve adhesion to the outer circumferential surface of the cathode ray tube neck portion 21. Reference numeral 200 is a clamp.

이와같이 구성된 본 고안에 음극선관용 편향요오크(100)를 음극 선관의 콘부(22)에 장착하기 위해서는 먼저 음극선관의 콘부(22)에 편향요오크(100)를 삽입함으로써 세퍼레이터(102)에 설치된 고정부(101)에 네크부(21)가 삽입되도록 한다.In order to mount the deflection yoke 100 for the cathode ray tube to the cone portion 22 of the cathode ray tube according to the present invention configured as described above, the deflection yoke 100 is first inserted into the cone portion 22 of the cathode ray tube, thereby being installed in the separator 102. The neck portion 21 is inserted into the government 101.

이 상태에서 클램프(200)를 이용하여 고정부의 위주면을 감싸 조여 고정부(101)의 절개편(101a)이 음극선관의 네크부(21)에 밀착되도록 함으로써 편향요오크(100)를 음극선관의 네크부에 고정한다. 상기와 같이 네크부(21)에 고정부(101)를 고정하게되면 상기 절개편(101)의 내면에는 흡착부(101b)가 형성되어 있으므로 절개편(101a)과 네크부(21)의 밀착력을 향상시킬 수 있다. 이를 더욱 상세하게 설명하면 상기 절개편(101a)의 내면에 형성된 흡착부(101b)는 돌출된 평활면(101c)에 인입홈(101d)이 형성되어 있으므로 네크부(21)와의 밀착시 네크부(21)가 외주면에 평활면이 흡착되게 되어 절개편(101a)과 네크부(21)의 결합력을 향상시킬 수 있는 것이다.In this state, the clamp 200 is wrapped around the circumferential surface of the fixing part and tightened so that the cut piece 101a of the fixing part 101 comes into close contact with the neck portion 21 of the cathode ray tube. Fix it to the neck of the tube. When the fixing portion 101 is fixed to the neck portion 21 as described above, since an adsorption portion 101b is formed on the inner surface of the cut portion 101, the adhesion between the cut portion 101a and the neck portion 21 is improved. Can be improved. In more detail, the suction portion 101b formed on the inner surface of the cut piece 101a has an inlet groove 101d formed on the protruding smooth surface 101c, so that the neck portion (when in close contact with the neck portion 21) is formed. The smooth surface is adsorbed on the outer circumferential surface 21 to improve the bonding force between the cut piece 101a and the neck portion 21.

이와같이 본 고안 음극선관용 편향요오크는 그 고정부의 절개편에 흡착부를 형성함으로써 네크부와 고정부의 결합력을 향상시킬 수 있고 나아가서는 펀넬에 대한 편향요오크의 흔들림을 방지하여 전자총으로부터 방출된 전자빔의 편향시 전자빔의 편향이 왜곡되는 것을 방지할 수 있다.Thus, the deflection yoke for the cathode ray tube of the present invention can improve the coupling force of the neck portion and the fixing portion by forming an adsorption portion in the cutout portion of the fixing portion, and further, prevent the shaking of the deflection yoke to the funnel, thereby preventing the electron beam emitted from the electron gun. It is possible to prevent the deflection of the electron beam from being distorted at the time of deflection.
