본 고안은 흑백모니터의 음극선관(CRT)에 장착되어 전자비임을 수평 및 수직으로 편향시키는 편향요크의 하단부에 환설된 링홀더에 있어서, 링홀더 외주연부의 함실외측부에 결합돌기를 돌설하여 바아마그네트를 견고히 결합되도록한 편향요크용 링홀더의 바아마그네트 결합구조에 관한 것이다.The present invention is a ring holder attached to the cathode ray tube (CRT) of the monochrome monitor and rotated at the lower end of the deflection yoke for deflecting the electron beam horizontally and vertically, and the bar magnet is formed by protruding the engaging projection at the outer side of the compartment of the outer edge of the ring holder. It relates to a bar magnet coupling structure of the ring holder for the deflection yoke to be firmly coupled.

주지된 바와같이 링홀더는 캐소우드에서 나온 전자비임을 수평편향 및 수직편향시키는 편향요크의 하단부에 환설되어 디스토숀(Distortion)을 보정하기 위하여 바아마그네트를 취부하여 사용되는 것이다. 그러나 종래의 바아마그네트 결합구조는 제4도에 도시한 바와같이 링홀더(21)의 외주연부에 개구부(23)가 형설된 함실(22)을 형성하여, 함실(22) 내부에 바아마그네트(27)을 삽입한 후 접착제(28)로 도포하여 결합고정 하였다.As is well known, the ring holder is used by attaching a bar magnet to correct distortion in the lower part of the deflection yoke for horizontal and vertical deflection of the electron beam from the cathode. However, in the conventional bar magnet coupling structure, as shown in FIG. 4, the bar 22 is formed in the outer periphery of the ring holder 21 with the opening 23 formed therein, and the bar magnet 27 is formed inside the compartment 22. ) Was inserted and then fixed by bonding with an adhesive (28).

그런데 이와같이 개구부(23)가 형설된 함실(27) 내부에 바아마그네트(27) 삽입시에는 바아마그네트(27)의 좌우축이 틀어지면서 삽입되므로 함실의 저면까지 삽입이 불가능하여 디스토숀이 발생될뿐만 아니라, 정확히 삽입된 바아마그네트(27) 유동을 방지하기 위하여 최종적으로 접착제(28)을 도포하므로서 작업공수 및 원가상승의 문제점이 있었다.However, when the bar magnet 27 is inserted into the compartment 27 in which the opening 23 is formed, the left and right axes of the bar magnet 27 are distorted, so it is impossible to insert the bottom magnet of the compartment, causing distortion. Rather, there is a problem of workmanship and cost increase by finally applying the adhesive 28 to prevent the bar magnet 27 is correctly inserted.

따라서 본 고안은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 링홀더의 외주연부에 개구부가 형설된 함실의 외측벽에 확인구를 형성하고 탄성력이 있는 결합돌기를 내측으로 돌설하여 바아마그네트를 함실 외측벽에 돌설된 결합돌기에 견고히 지지토록 하여 디스토숀 발생방지함과 동시에 작업공수 및 원가절감을 하려는 것이 목적이다. 상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the above problems, forming a check hole on the outer wall of the chamber formed with an opening in the outer periphery of the ring holder and protruding elastic coupling protrusion inward to the bar magnet on the outer wall of the chamber The purpose is to prevent the occurrence of distortion and to save the labor and cost by firmly supporting the protruding coupling protrusion. Referring to the present invention in detail based on the accompanying drawings that can achieve the above object is as follows.

제1도에서 제3도에 도시한 바와같이 편향요크의 하단부에 환설 고정되는 링홀더(1)의 외주연부에 개구부(3)가 형설된 함실(2)을 형성하고, 함실(2)의 외측벽(4) 하단부에 확인구(5)을 형설하고, 내측면 양측으로 탄성력이 있는 결합돌기(6)(6')을 돌설한 것이다.As shown in FIG. 1 to FIG. 3, a compartment 2 having an opening 3 is formed in the outer periphery of the ring holder 1 which is circularly fixed to the lower end of the deflection yoke, and the outer wall of the compartment 2 is formed. (4) The confirmation port 5 is formed in the lower end, and the engaging projection 6, 6 'which has elasticity is protruded on both sides of an inner side surface.

미설명부호 7은 바아마그네트이다.Reference numeral 7 is a bar magnet.

이와같이 구성된 본 고안은 바아마그네트(7)을 링홀더(1)의 외주연부에 형성된 함실(2)의 개구부(3)에 삽입시 바아마그네트(7)의 양측부를 밀어 넣으면 외측벽(4) 내면양측에 돌설된 결합돌기(6)(6')가 탄성력을 발휘하면서 삽입된 후 결합돌기(6)(6')는 스프링백에 의하여 함실하단에 바아마그네트(7)가 견고히 결합되며 바아마그네트(7)가 정확히 결합된 상태의 확인은 확인구(5)을 통하여 간편히 확인된다.According to the present invention, the bar magnet 7 is inserted into the opening 3 of the compartment 2 formed in the outer periphery of the ring holder 1, so that both sides of the bar magnet 7 are pushed into the inner wall on both sides of the outer wall 4. After the protruding coupling protrusions 6 and 6 'are inserted while exerting elastic force, the coupling protrusions 6 and 6' are firmly coupled to the bar magnets 7 by the spring back and the bar magnets 7. Confirmation of the state of exactly combined is easily confirmed through the confirmation port (5).

이상설명한 바와같은 본 고안은 바아마그네트를 함실의 외측벽에 탄성력이 있는 양측의 결합돌기에 부딪히면서, 삽입되므로 틀러져 조립됨이 없게 되어 디스토숀이 발생되지 않고, 완전조립된 바아마그네트는 양측의 결합돌기가 견고히 지지하므로서 접착제를 사용치 않아 원가가 절감됨은 물론 품질 및 생산성 향상에 현저한 효과가 있는 유용한 고안이다.As described above, the present invention hits the bar magnet against the engaging protrusion of both sides with elastic force on the outer wall of the compartment, so that there is no distortion and no assembly, so that the distortion does not occur, and the fully assembled bar magnet has the engaging protrusion of both sides. Since it is firmly supported, it is a useful design that has a significant effect on quality and productivity as well as cost reduction by not using an adhesive.
