이 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 코일세퍼레이터의 스크린부에 크로스아암(Cross Arm)이 견고하게 고정되어 제품의 불량률이 감소됨과 동시에 생산성이 향상되도록 한 편향요크의 크로스아암 고정장치에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a cross arm fixing device of a deflection yoke, in which a cross arm is firmly fixed to a screen portion of a coil separator to reduce product defect rate and to improve productivity. It is about.

일반적으로, TV수상기 또는 모니터 등의 음극선관(CRT)에 사용되는 편향요크(10)는 제1도에 나타낸 바와같이, 네크부(11)와 스크린부(12)로 이루어지는 코일세퍼레이터(13)의 내측면에 수평편향코일(14)이 감겨져 장착되며, 외측으로는 수직편향코일(15)이 감겨진 페라이트코어(16)가 코어클램프(17)에 의해 조립된다.In general, the deflection yoke 10 used in the cathode ray tube (CRT) such as a TV receiver or a monitor has a coil separator 13 including a neck portion 11 and a screen portion 12, as shown in FIG. The horizontal deflection coil 14 is wound around the inner side, and the ferrite core 16 wound around the vertical deflection coil 15 is assembled by the core clamp 17.

한편, 편향요크(10)를 음극선관에 장착한 후에, 수평 및 수직편향코일(14), (15)에 톱니파 펄스를 인가시키게 되면 자계가 형성되너 전자총에서 방사되는 R(적색), G(녹색), B(청색)의 전자빔을 평향시켜 화면상에 주사위치를 결정하는 것이나, 음극선관의 코마(Coma)수차나 편향요크(10)의 기구적인 오차에 의하여 화면상에 3가지의 빔이 한군데 집중되지 못하는 미스콘버젼스(Misconvergence)현상이 발생된다.On the other hand, after the deflection yoke 10 is mounted on the cathode ray tube, when a sawtooth pulse is applied to the horizontal and vertical deflection coils 14 and 15, a magnetic field is formed and R (red) and G (green) are emitted from the electron gun. ), The B (blue) electron beam is deflected to determine the dice on the screen, or the three beams are placed on the screen due to the coma aberration of the cathode ray tube or the mechanical error of the deflection yoke 10. Misconvergence occurs when it is not concentrated.

따라서, 종래에는 이러한 마스콘버젼스현상을 방지하기 위하여 제2도에 나타낸 바와같이, 코일세퍼레이터(13)의 스크린부(12) 상측면에 공간부(21)를 갖는 지지편(20a), (20b)을 양측으로 형성하고, 이 지지편(20a), (20b)의 공간부(21)에 자성체로 이루어지는 크로스아암(22)의 고정편(23)을 끼워맞춤시킨 후에, 지지편(20a), (20b)의 한쪽끝을 열에 의해 녹여 붙여 크로스아암(22)을 고정시켰다.Therefore, in order to prevent such masconvergence, conventionally, as shown in FIG. 2, the support pieces 20a and (with the space portion 21 on the upper surface of the screen portion 12 of the coil separator 13) ( 20b) is formed in both sides, and after fitting the fixing piece 23 of the cross arm 22 which consists of magnetic bodies to the space part 21 of this support piece 20a, 20b, the support piece 20a is carried out. , One end of (20b) was melted by heat to fix the cross arm (22).

그러나, 상기한 바와같은 종래의 크로스아암(22)의 고정장치는, 스크린부(12)에 형성된 지지편(20a), (20b)을 녹여붙이는 동안 크로스아암(22)이 유동되면서 고정위치가 변동되므로 미스콘버젼스현상을 보정하는데 지장이 초래되며, 녹여 붙여진 지지편(20a), (20b)의 고정력이 약하기 때문에 크로스아암(22)이 이탈되는 등 제품의 불량륭이 증가될 뿐만 아니라 작업공수의 증가로 생산성이 저하되는 문제점이 있었다.However, in the conventional fixing device of the cross arm 22 as described above, the fixing position is changed while the cross arm 22 flows while melting the supporting pieces 20a and 20b formed on the screen portion 12. Therefore, there is a problem in correcting the misconvergence phenomenon, and since the fixing force of the melted support pieces 20a and 20b is weak, the cross arm 22 is dislodged and the work quality of the product is increased as well. There was a problem that the productivity is lowered by the increase.

이 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 이 고안의 목적은 코일세퍼레이터의 스크린부 바깥둘에에 고정홀더 및 소정의 탄성력을 부여하는 탄성편이 각각 형성되어 크로스아암이 견고하게 고정되므로서, 크로스아암의 유동 및 이탈이 방지되어 고정위치가 일정하게 유지되면서 미스콘버젼현상의 보정이 용이해짐과 동시에 제품의 불량률이 저하되고, 작업공수의 감소로 생산성이 향상되도록 한 편향요크의 크로스아암 고정장치를 제공하는데 있다.The object of the present invention is to solve the problems described above, and an object of the present invention is to provide a fixed holder and an elastic piece for imparting a predetermined elastic force to the outside of the screen portion of the coil separator so that the cross arms are firmly fixed. The cross arm is fixed to the deflection yoke, which prevents the flow and separation of the cross arm, so that the fixed position is kept constant, making it easier to correct the misconversion phenomenon, lowering the defective rate of the product, and improving productivity by reducing the number of labors. To provide a device.

이하, 이 고안에 따른 편향요크의 크로스아암 고정장치를 첨부된 도면에 의하여 상세하게 설명한다.Hereinafter, the cross-arm fixing device of the deflection yoke according to the present invention will be described in detail with reference to the accompanying drawings.

제3도 및 제4도는 이 고안에 따른 크로스아암의 고정장치를 설명하기 위해 바람직한 실시예를 나타낸 도면으로서, 먼저 편향요크(10)는 네크부(11)와 스크린부(12)로 이루어지는 코일세퍼레이터(13)의 내측면에 수평편향코일(14)이 감겨져 장착되며, 외측으로느 수직편향코일(15)이 감겨진 페라이트코어(16)가 코어클램프(17)에 의해 조립된다.3 and 4 show a preferred embodiment for explaining the fixing device of the cross arm according to the present invention. First, the deflection yoke 10 has a coil separator comprising a neck portion 11 and a screen portion 12. The horizontal deflection coil 14 is wound and mounted on the inner side of (13), and the ferrite core 16, on which the vertical deflection coil 15 is wound, is assembled by the core clamp 17.

또한, 코일세퍼레이터(13)의 스크린부(12) 상측면에 공간부(31)를 갖는 지지편(20a), (20b)이 양측으로 형성되고, 스크린부(12)의 바깥둘레에는 소정간격으로 떨어져 고정홀더(32a), (32b)가 양측에 각각 형성되며, 고정홀더(32a), (32b)의 사이에 소정의 탄성력이 부여되도록 탄성편(33a),(33b)이 각각 형성된다.In addition, support pieces 20a and 20b having a space portion 31 on the upper surface of the screen portion 12 of the coil separator 13 are formed on both sides, and the outer periphery of the screen portion 12 at predetermined intervals. The fixing holders 32a and 32b are formed on both sides, respectively, and the elastic pieces 33a and 33b are formed so that a predetermined elastic force is applied between the fixing holders 32a and 32b.

그리고, 크로스아암(34)의 중앙부분에 지지편(31a), (30b)의 공간부(31)에 끼워맞춤되는 고정편(35)이 형성되며 양끝단에는 안낸편(36a), (36b)이 형성되어 고정홀더(32a), (32b)에 끼워맞춤되고, 크로스아암(34)의 조립공(37a), (37b)은 탄성편(33a), (33b)에 끼워맞춤되어 소정의 탄성력으로 크로스아암(34)이 견고하게 고정된다.In addition, a fixing piece 35 is formed at the central portion of the cross arm 34 to fit into the space 31 of the support pieces 31a and 30b, and at both ends, the fixing pieces 35a and 36b are provided. Are formed and fitted to the fixed holders 32a and 32b, and the assembling holes 37a and 37b of the cross arms 34 are fitted to the elastic pieces 33a and 33b to cross each other with a predetermined elastic force. Arm 34 is firmly fixed.

상술한 바와같은 이 고안에 따른 편향요크의 크로스아암 고정장치에서는 코일세퍼레이터(13)의 스크린부(12) 상측면에 형성된 지지편(30a), (30b)의 공간부(31)에 크로스아암(34)의 고정편(35)이 끼워맞춤되고, 크로스아암(34)의 안내편(36a), (36b)이 스크린부(12)의 바깥둘레에 형성된 고정홀더(32a), (32b)에 견고하게 고정되도록 끼워맞춤으로서, 크로스아암(34)이 내측방향이나 혹은 좌, 후방향으로 유동되지 않는다.In the cross arm fixing device of the deflection yoke according to the present invention as described above, the cross arm is formed on the space 31 of the support pieces 30a and 30b formed on the upper surface of the screen portion 12 of the coil separator 13. The fixing piece 35 of 34 is fitted, and the guide pieces 36a, 36b of the cross arm 34 are firmly fixed to the fixing holders 32a, 32b formed on the outer circumference of the screen portion 12. By fitting so as to be securely fixed, the cross arm 34 does not flow inward, or in left and rear directions.

또한, 스크린부(12)의 탄성편(33a), (33b)에 조립공(37a), (37b)이 끼워맞춤되면서 소정의 탄성력을 부여받아 외측방향으로 크로스아암(34)의 유동 및 이탈이 방지되어 고정위치가 일정하게 유지되므로 미스콘버젼스의 보정이 용이해짐과 동시에 제품의 불량률이 저하된다.In addition, as the assembly holes 37a and 37b are fitted to the elastic pieces 33a and 33b of the screen part 12, a predetermined elastic force is applied to prevent the flow and separation of the cross arm 34 in the outward direction. Since the fixed position is kept constant, misconvergence correction becomes easy and the defective rate of the product is reduced.

그리고, 상기한 크로스아암(34)의 고정장치는, 종래에 크로스아암(22)을 코일세퍼레이터(13)의 스크린부(12)상측면에 형성된 지지편(20a), (20b)을 녹여붙여 고정시키는 방식보다 조립공정수가 감소되어 제품의 생산성이 향상된다.In the fixing device of the cross arm 34, the support arm 20a, 20b formed on the upper side of the screen portion 12 of the coil separator 13 is fixed by melting the cross arm 22 conventionally. The number of assembly processes is reduced compared to the method of increasing the productivity of the product.

이상에서와 같이 이 고안에 따른 편향요크의 크로스아암 고정장치는, 코일세퍼레이터의 스크린부 바깥둘에에 크로스아암이 유동 및 이탈이 방지되도록 견고하게 고정되므로서, 화면상에 발생되는 미스콘버젼스현상의 보정이 용이해짐과 동시에 제품의 불량률이 저하되며, 작업공수의 감소로 생산성이 향상되도록 한 유용한 고안인 것이다.As described above, the deflection yoke crossarm fixing device according to the present invention is securely fixed to the outside of the screen portion of the coil separator so that the flow and departure of the crossarm, resulting in misconvergence generated on the screen. It is a useful design that improves the productivity by reducing the defect rate of the product and at the same time ease the correction of the phenomenon.
