이 고안은 편향요크에 관한 것으로서, 더욱 상세하게는 화면상에 발생되는 디스토션(Distortion) 현상등을 보정하기 위해 다수개의 마그네트가 장착되는 프론커버를 보빈에 견고하게 조립하여 유동 및 이탈을 방지함과 동시에 화면의 특성을 향상시킬 수 있도록 한 것이다.The present invention relates to a deflection yoke, and more specifically, a front cover, which is equipped with a plurality of magnets, is firmly assembled to a bobbin to prevent flow and departure, in order to compensate for distortion occurring on the screen. At the same time, the characteristics of the screen are to be improved.

종래에 TV수상기 또는 모니터등의 음극선관(CRT)에 사용되는 편향요크(10)는 제1도의 (a), (b)에 나타낸 바와같이, 네크부(11)와 스크린부(12)로 이루어지는 보빈(13)의 내측에 수평편향코일(14)이 감겨져 장착되며, 외측으로는 수직편향코일(15)이 감겨진 페라이트코어(16)가 코어플램프(17)에 의해 조립된다.The deflection yoke 10 conventionally used for a cathode ray tube (CRT) such as a TV receiver or a monitor is composed of a neck portion 11 and a screen portion 12, as shown in FIGS. 1A and 1B. The horizontal deflection coil 14 is wound and mounted inside the bobbin 13, and the ferrite core 16, on which the vertical deflection coil 15 is wound, is assembled by the core lamp 17.

한편, 상기 편향요크(10)를 음극선관에 장착하여 수평 및 수직편향코일(14),(15)에 톱니파 펄스를 인가시키면 플레밍의 왼손법칙에 의하여 전자촉에서 방사되는 R(적색), G(녹색), B(청색)의 전자빔을 편향시켜 화면상에 주사위치를 결정하게 되는 것이나, 음극선관의 기구적인 메카니즘에 의한 오차 및 편향요크(10)의 자체적인 오차에 의하여 화면상에는 디스토션 및 버티컬 센터 라스터(Vertical Center Raster)현상등이 발생되며, 상기 디스토션 현상등을 보정하기 위하여 보빈(13)의 스크린부(12)에는 다수의 마그네트(18)가 고정홀더(19)에 장착되는 프로트커버(20)가 걸림편(21)에 의해 조립된다.On the other hand, when the deflection yoke 10 is mounted on the cathode ray tube and a sawtooth pulse is applied to the horizontal and vertical deflection coils 14 and 15, R (red), G ( Distortion and vertical centers on the screen are deflected on the screen by deflecting green and B (blue) electron beams, or by errors caused by the mechanical mechanism of the cathode ray tube and the error of the deflection yoke 10 itself. Raster (Vertical Center Raster) phenomenon is generated, in order to correct the distortion phenomenon, the front cover 12 of the bobbin 13, a plurality of magnets 18 are mounted on the fixed holder (19) 20 is assembled by the locking piece 21.

그러나, 상기 같이 보빈(13)의 스크린부(12)에 프로트커버(20)가 걸림편(21)에 의해서만 조립될 경우에는, 상기 프로트커버(20)의 이탈을 방지할수 있으나 좌, 우측방향의 유동은 방지할 수 없기때문에 마그네트(18)의 장착위치가 변동되므로 디스토션 현상등의 보정에 지장이 초래되는 문제점이 있었다.However, when the front cover 20 is assembled to the screen portion 12 of the bobbin 13 only by the locking pieces 21, the detachment of the front cover 20 may be prevented, but the left and right directions may be prevented. Since the flow cannot be prevented, the mounting position of the magnet 18 is changed, which causes a problem in the correction of distortion and the like.

따라서, 보빈(13)의 스크린부(12)에 접착제(22)를 도포하여 프로트커버(20)를 고정시키는 방식이 사용되고 있으나, 이는 접착제(22)를 고정시키는 방식이 사용되고 있으나, 이는 접착제(22)를 도포시키는 작업공정이 번거로울 뿐만아니라 접착제(22)의 흘러내림현상등이 발생되어 제품의 외관불량이 발생되는 등 작업성이 저하되는 문제점이 있었다.Therefore, the method of fixing the front cover 20 by applying the adhesive 22 to the screen portion 12 of the bobbin 13 is used, but the method of fixing the adhesive 22 is used, which is an adhesive 22 ) Is not only cumbersome, but also has a problem in that workability is degraded, such as a drop in the adhesive 22, resulting in poor appearance of the product.

이 고안은 상기와 같은 문제점을 해결하기 위한 것으로서, 이 고안의 목적은 보빈의 스크린부 바깥둘레에 양측으로 걸림홈을 갖는 "T"자형의 고정편을 형성하여 복수개의 걸림편으로 다수의 마그네트가 장착되는 프론트커버를 견고하게 고정시킴으로써, 상기 프론트커버의 유동 및 이탈이 방지되어 화면상에 발생되는 디스토션 현상등이 용이하게 보정되므로 제품의 신뢰성이 향상됨과 동시에 종래의 편향요크에서 프론트커버를 고정시키는 접착제의 도포공정이 불필요해지는등 작업성이 향상되도록 한 편향요크를 제공하는데 있다.This invention is to solve the above problems, the purpose of this invention is to form a "T" shaped fixing piece having locking grooves on both sides on the outer circumference of the bobbin, a plurality of magnets as a plurality of locking pieces By firmly fixing the front cover to be mounted, the movement and separation of the front cover is prevented to easily correct the distortion phenomenon generated on the screen, thereby improving the reliability of the product and at the same time fixing the front cover in the conventional deflection yoke It is to provide a deflection yoke that improves workability, such as unnecessary adhesive application step.

상기와 같은 목적을 달성하기 위한 이 고안의 특징은, 화면상에 발생되는 디스토션을 보정하기 위해 다수의 마그네트가 장착되는 프론트커버가 보빈의 스크린부에 조립되도록 한 편향요크에 있어서, 상기 보빈의 스크린부 바깥둘레에 양측으로 걸림홈을 갖는 "T"자형의 고정편이 형성되며, 프론트커버의 내측면에 형성되는 복수개의 걸림편이 상기 고정편의 걸림홈에 각각 끼워맞춤되도록 한편향요크에 있다.A feature of this invention for achieving the above object is that in the deflection yoke in which the front cover on which the plurality of magnets are mounted is assembled to the screen portion of the bobbin to correct distortion generated on the screen, the screen of the bobbin A "T" shaped fixing piece having locking grooves on both sides is formed in the outer outer circumference, and a plurality of locking pieces formed on the inner side of the front cover are on the one side yoke so as to fit in each of the locking grooves of the fixing piece.

이하, 이 고안에 따른 편향요크를 첨부된 도면에 의하여 상세하게 설명한다.Hereinafter, the deflection yoke according to the present invention will be described in detail with reference to the accompanying drawings.

제2도의 (a), (b)는 이고안에 따른 편향요크를 설명하기 위해 바람직할 실시예를 나타낸 도면으로서, 먼저 편향요크(10)는 제1도의 (a)에 나타내어 이미 설명한 바와같이 네크부(11)와 스크린부(12)로 이루어지는 보빈(13)의 내, 외측에 수평 및 수직편향코일(14), (15)이 각각 감겨져 장착된다. 이때, 상기 보빈(13)의 스크린부(12)바깥둘레에는 직선면(30)이 형성되며, 상기 스크린부(12)의 직선면(30)상에 양측으로 걸림홈(31a),(31b)을 갖는 "T"자형의 고정편(32)이 형성된다.(A) and (b) of FIG. 2 show a preferred embodiment for explaining the deflection yoke according to Io, and the deflection yoke 10 is first shown in (a) of FIG. Horizontal and vertical deflection coils 14 and 15 are wound and mounted on the inside and outside of the bobbin 13 composed of the 11 and the screen portion 12, respectively. At this time, a straight surface 30 is formed on the outer circumference of the screen portion 12 of the bobbin 13, and engaging grooves 31a and 31b on both sides on the straight surface 30 of the screen portion 12. A fixing piece 32 having a "T" shape is formed.

또한, 프론트커버(33)는 그 바깥둘레에 마그네트(34)가 장착되는 고정홀더(35)가 형성되며, 상기 프로트커버(33)의 내측면에는 복수개의 걸림편(36a),(36b)이 각각 형성되어 스크린부(12)에 형성되는 고정편(32)의 걸림편(31a),(31b)이 각각 형성되어 스크린부(12)에 형성되는 고정편(32)의 걸림홈(31a), (31b)에 각각 끼워맞춤된다.In addition, the front cover 33 is formed with a fixing holder 35, the magnet 34 is mounted on the outer circumference, a plurality of engaging pieces (36a, 36b) on the inner surface of the front cover (33) Locking grooves 31a and 31b of the fixed piece 32, respectively formed and formed on the screen portion 12 are formed, respectively, the locking groove 31a of the fixed piece 32 formed on the screen portion 12, Fit to 31b respectively.

상술한 바와같이 이 고안에 따른 편향요크(10)에서는 보빈(13)의 스크린부(12)에 형성되는 고정편(32)의 걸림홈(31a),(31b)에 복수개의 걸림편(36a),(36b)이 끼워맞춤되면서 프로트커버(33)가 견고하게 고정되므로 상기 프로트커버(33)의 유동 및 이탈이 방지된다.As described above, in the deflection yoke 10 according to the present invention, a plurality of engaging pieces 36a are provided in the engaging grooves 31a and 31b of the fixing piece 32 formed in the screen portion 12 of the bobbin 13. Since the cover 36 is firmly fixed while the 36b is fitted, the flow and departure of the cover 33 are prevented.

따라서, 상기 프로트커버(33)의 고정홀더(35)에 장착되는 마그네트(34)의 장착위치가 일정하게 유지되어 화면상에 발생되는 디스토션현상등이 용이하게 보정되므로 화면을 특성을 향상시키게 되고, 상기 마그네트(34)는 디스토션현상의 크기에 따라 가우스(Gauss)량이 조정되어 장착된다.Therefore, since the mounting position of the magnet 34 mounted on the fixing holder 35 of the front cover 33 is kept constant, distortion caused on the screen can be easily corrected, thereby improving the characteristics of the screen. The magnet 34 is mounted by adjusting the amount of Gauss according to the magnitude of the distortion phenomenon.

또한, 이 고안의 프로트커버(33)는 복수개의 걸림편(36a), (36b)에 의해 보빈(13)에서 유동이 방지되어 고정되므로, 종래의 편향요크(10)에서 보빈(13)의 스크린부(12)에 접착제(22)를 도포하여 프로트커버(20)를 고정시키는 도포공정이 불필요해져 작업성이 향상되고, 접착제(22)가 경화시간도중 흘러내리는 현상이 제거되어 제품의 외관불량이 방지된다.In addition, the front cover 33 of the present invention is prevented and fixed in the bobbin 13 by a plurality of engaging pieces (36a, 36b), so that the screen of the bobbin 13 in the conventional deflection yoke (10) The coating process of fixing the front cover 20 by applying the adhesive 22 to the part 12 is unnecessary, and workability is improved, and the phenomenon that the adhesive 22 flows down during the curing time is eliminated. Is prevented.

이상에서와 같이 이 고안에 따른 편향요크는 다수의 마그네트가 장착되는 프론트커버를 복수개의 걸림편으로 보빈에 견고하게 고정시킴으로써 유동 및 이탈이 방지되어 화면의 특성 및 신뢰성이 향상됨과 동시에 접착제의 사용이 불필요해지는등 작업성이 향상되는 유용한 고안인 것이다.As described above, the deflection yoke according to the present invention secures the front cover on which the magnets are mounted to the bobbin with a plurality of engaging pieces, thereby preventing the flow and departure, thereby improving the characteristics and reliability of the screen and at the same time using the adhesive. It is a useful design that improves workability such as becoming unnecessary.
