이 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 전자총에서 방사되는 전자빔을 편향시키기 위하여 음극선관(CRT)에 장착되는 편향요크를 고정시키기 위한 편향요크 고정장치에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a deflection yoke fixing device for fixing a deflection yoke mounted on a cathode ray tube (CRT) to deflect an electron beam emitted from an electron gun.

일반적으로, 제1도에 나타낸 바와 같이 편향요크(1)는 네크측(2)과 스크린측(3)으로 이루어지는 코일세퍼레이터(4) 내측에 수평편향코일이 감겨지고, 외측으로는 수직편향코일이 감겨진 페라이트 코어(5)가 조립되는 것으로서, 상기와 같은 편향요크(1)를 음극선관(6)의 네크부(6a)에 장착한 후 상기 편향요크(1)의 네크측(2)에 형성된 리브(2a)에 장착된 요크클램프(7)의 고정나사(8)를 조임방향으로 전진시켜 고정시키게 된다.In general, as shown in FIG. 1, the deflection yoke 1 is wound with a horizontal deflection coil inside the coil separator 4 including the neck side 2 and the screen side 3. As the wound ferrite core 5 is assembled, the deflection yoke 1 is mounted on the neck portion 6a of the cathode ray tube 6 and formed on the neck side 2 of the deflection yoke 1. The fixing screw 8 of the yoke clamp 7 mounted on the rib 2a is advanced in the tightening direction to be fixed.

즉, 상기한 종래의 요크클램프(7)는, 제2a도, 제2b도에 나타낸 바와같이 양끝단에 조임편(9a), (9b)이 형성되고, 이 조임편(9a), (9b)에 고정나사(8)가 체결 되어있다. 따라서, 상기 편향요크(1)를 음극선관(6)에 장착한 후 드라이버 등을 사용하여 고정나사(8)를 조임방향으로 전진시킴으로써, 편향요크(1)를 음극선관(6)에 고정시키게 된다.That is, in the conventional yoke clamp 7, the tightening pieces 9a and 9b are formed at both ends as shown in FIG. 2A and FIG. 2B, and the tightening pieces 9a and 9b. The fixing screw (8) is fastened to the Accordingly, the deflection yoke 1 is fixed to the cathode ray tube 6 by attaching the deflection yoke 1 to the cathode ray tube 6 and then advancing the fixing screw 8 in the tightening direction by using a screwdriver or the like. .

그러나, 상기와 같은 종래의 요크클램프(7)는 고정나사(8)를 체결하는 과정에서 조임편(9a), (9b)에 휨현상이 발생하여 정확한 체결이 곤란한 문제가 있고, 편향요크(1)의 위치조정을 위하여 관축을 기준으로 회전시킬 경우에는 요크클램프(7)의 고정나사(8)를 풀고난후에 편향요크(1)를 회전시켜야 하므로 작업이 번거로울 뿐만 아니라 위치규제가 제대로 이루어지지 않고 틀어져버리는 문제점이 있었다.However, in the conventional yoke clamp 7 as described above, there is a problem in that bending is generated in the tightening pieces 9a and 9b in the process of fastening the fixing screw 8, so that the precise fastening is difficult, and the deflection yoke 1 In order to adjust the position of the pipe shaft, the deflection yoke (1) must be rotated after loosening the fixing screw (8) of the yoke clamp (7). There was a problem throwing away.

이 고안은 상기와 같은 문제점을 해결하기 위한 것으로, 이 고안의 목적은, 편향요크의 네크측에 회동편을 장착하여 편향요크와 동시에 회동가능하도록 함으로써, 편향요크의 위치규제 및 회전조작이 정확히 이루어질 수 있도록 한 편향요크 고정장치를 제공함에 있다.The object of the present invention is to solve the above problems, and the object of the present invention is to mount the rotating piece on the neck side of the deflection yoke so that it can be rotated at the same time as the deflection yoke, so that the position control and rotational operation of the deflection yoke are made accurately. It is to provide a deflection yoke fixing device.

상기와 같은 목적을 달성하기 위한 이 고안의 특징은, 음극선관이 네크부에 장착되는 편향요크를 요크클램프에 의해 고정시킴에 있어서, 소정간격을 두고 양측에 형성된 원판형상의 리브들 사이에 톱니부가 형성되고, 그 상측에는 상기 톱니부와 맞물리는 이송나사가 지지벽에 장착된 회동편을 상기 편향요크의 네크측에 형성된 리브에 장착하여서 된 편향요크 고정장치에 있다.A feature of this invention for achieving the above object is that, in fixing the deflection yoke in which the cathode ray tube is mounted on the neck by the yoke clamp, the teeth are provided between the disc-shaped ribs formed on both sides at a predetermined interval. A deflection yoke fixing device is formed, and on the upper side thereof, a rotating screw, which is engaged with the teeth, is mounted on a rib formed on the neck side of the deflection yoke.

이하, 이 고안에 따른 편향요크 고정장치에 대한 실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, an embodiment of the deflection yoke fixing device according to the present invention will be described in detail by the accompanying drawings.

먼저, 제1도의 종래예에서 이미 설명한 바와같이 음극선관(6)의 네크부(6a)에 장착되는 편향요크(1)의 구조는 동일한 것이며, 이 고안에 있어서는 편향요크(1)의 네크측(2)에 형성된 리브(2a)에 제3a도, 제3b도에 나타낸 바와같은 회동편(10)이 장착되어 이송나사(11)에 의해 편향요크(1)를 미세 회전시킬 수 있도록 한 것이다.First, as already described in the conventional example of FIG. 1, the structure of the deflection yoke 1 mounted on the neck portion 6a of the cathode ray tube 6 is the same, and in this design, the neck side of the deflection yoke 1 ( The rotating piece 10 as shown in FIG. 3A and FIG. 3B is attached to the rib 2a formed in 2) so that the deflection yoke 1 can be minutely rotated by the feed screw 11.

상기 회동편(10)에는, 소정간격을 두고 원판형상의 리브(12a), (12b)들이 형성되어 있고, 이 리브(12a), (12b)들 사이에 톱니부(13)가 형성되어 있으며, 이 톱니부(13)의 상측에는 상기 양측의 리브(12a), (12b)를 연결하는 지지벽(13a)에 이송나사(11)를 장착하여 상기 톱니부(13)와 맞물리도록 되어있다.In the rotating piece 10, disc-shaped ribs 12a and 12b are formed at predetermined intervals, and the teeth 13 are formed between the ribs 12a and 12b. The feed screw 11 is attached to the support wall 13a for connecting the ribs 12a and 12b on both sides above the tooth portion 13 so as to be engaged with the tooth portion 13.

또한, 상기 일측의 리브(12a)에는 탄성리브(12c)가 일체로 형성되어 이 외주면에 제4a도, 제4b도에서와 같이 요크클램프(7)가 장착될 수 있도록 구성되어 있다.In addition, the rib 12a on one side is formed so that the elastic rib 12c is integrally formed so that the yoke clamp 7 can be mounted on the outer circumferential surface as shown in FIGS. 4a and 4b.

상기한 바와 같이 구성된 이 고안은, 제4도의 제4a도, 제4b도에서와 같이 음극선관(6)의 네크부(6a)에 장착된 편향요크(1)의 리브(2a)에 회동편(10)을 끼워 장착시킨 후, 상기 회동편(10)의 탄성리브(12c) 외측에 설치된 요크클램프(7)를 조여줌으로써, 음극선관(6)에 편향요크(1)를 고정시킬 수 있게된다.This design, constructed as described above, has a pivoting piece (2) on the rib (2a) of the deflection yoke (1) mounted on the neck (6a) of the cathode ray tube (6) as shown in FIGS. 4a and 4b of FIG. 10), the deflection yoke 1 can be fixed to the cathode ray tube 6 by tightening the yoke clamp 7 provided on the outer side of the elastic rib 12c of the pivoting piece 10.

상기와 같은 상태에서 상기 음극선관(6)의 관축을 기준으로하여 편향요크(1)의 조립위치를 수정하고자 할 경우에는 상기 회동편(10) 상측에 장착되어 있는 이송나사(11)를 드라이버등으로 돌려줌에 따라 이송나사(11)와 맞물려 있는 회동편(10)의 톱니부(13)에 의해 회동편(10)이 미세 회전하게 되므로, 음극선관(6)에 대한 편향요크(1)의 위치를 정확하게 조정할 수 있는 것이다.If you want to modify the assembly position of the deflection yoke (1) on the basis of the tube axis of the cathode ray tube (6) in the above state, the transfer screw 11 mounted on the upper side of the rotating piece (10) As the turning piece 10 rotates finely by the teeth 13 of the rotating piece 10 engaged with the feed screw 11, the position of the deflection yoke 1 with respect to the cathode ray tube 6 is turned. Can be adjusted accurately.

그후에 조정이 완료된 상태에서 상기 이송나사(11) 부위를 본딩(Bonding)처리 함으로써, 음극선관(6)에 편향요크(1)를 고정시킬 수 있게된다.After that, by bonding the portion of the transfer screw 11 in a state where adjustment is completed, the deflection yoke 1 can be fixed to the cathode ray tube 6.

이상에서와 같이 이 고안은, 음극선관에 장착되는 편향요크를 회동편에 장착된 요크클램프로 견고하게 고정시킬 수 있는 동시에 편향요크를 미세 회전조정이 가능하도록 함으로써, 음극선관 정착시의 조립산포를 최소화 할 수 있도록하여 제품의 품질을 향상시킬 수 있는 것이다.As described above, the present invention enables the deflection yoke mounted on the cathode ray tube to be firmly fixed by the yoke clamp mounted on the rotating piece, and the deflection yoke can be finely adjusted, thereby preventing the assembly dispersion during the cathode ray tube fixing. By minimizing the quality of the product can be improved.
