Description

음극선관용 편향요크 {Deflection yoke of brown ray tube}Deflection yoke of brown ray tube {Deflection yoke of brown ray tube}

본 발명은 음극선관의 편향요크에 설치되어 전자빔을 편향시키는 편향코일에 관한 것으로, 특히 편향코일의 내벽에 경사부를 변경하여 편향감도를 향상시킴과 더불어 디스토션의 보정에 따른 작업공수를 절감시킬 수 있도록 된 음극선관용 편향요크에 관한 것이다.The present invention relates to a deflection coil installed in a deflection yoke of a cathode ray tube for deflecting an electron beam, and in particular, by changing an inclined portion on an inner wall of the deflection coil to improve deflection sensitivity and to reduce workmanship due to distortion correction. It relates to a deflection yoke for a cathode ray tube.

일반적으로, 음극선관(100)은, 도 1에서와 같이, 전방패널(110)의 내벽에 도포되어 적색(R)과 녹색(G)과 청색(B)으로 발광됨과 더불어 섀도우마스크(130)를 통해 색구분되는 형광면(120)과, 전방패널(110)의 후방측에 결합되어 내부를 진공상태로 유지시키는 펀넬(140), 펀넬(140)의 후방측에 결합됨과 더불어 그 내부공간에 전자빔(165)을 발사하는 전자총(155)을 내장한 네크부(150) 및; 펀넬(140)의 외측면에 장착되어 전자빔(165)을 수평방향 또는 수직방향으로 편향시키는 편향요크 (160)로 구성된다.In general, as shown in FIG. 1, the cathode ray tube 100 is applied to the inner wall of the front panel 110 to emit light in red (R), green (G), and blue (B), as well as the shadow mask 130. It is coupled to the fluorescent surface 120 that is color-coded through the front panel 110, the funnel 140, which is coupled to the rear side of the front panel 110 to maintain the interior in a vacuum state, and the electron beam in the interior space of the funnel 140 A neck portion 150 having an electron gun 155 for firing 165 therein; It is mounted to the outer surface of the funnel 140 is composed of a deflection yoke 160 for deflecting the electron beam 165 in the horizontal or vertical direction.

그리고, 편향요크(160)는, 도 2에서와 같이, 음극선관(100)의 후단부에 링밴드(170)를 매개로 결합된 상태에서, 개구부(A)의 둘레면에 장착되어 전자빔(165)을 수평 방향으로 편향시키는 수평편향코일(162)과, 수평편향코일(162)의 후방측에 홀더(163)를 통해 장착되어 절연됨과 더불어 전자빔(165)을 수직방향으로 편향시키는 수직편향코일(164), 수직편향코일(164)의 후방측에 구비되어 코일(162,164)의 전류에 의해 발생하는 자기력을 손실을 줄여주는 페라이트코어(166), 네크부(B)의 둘레면에 장착되어 수직베럴형자계에 의해 발생하는 콤마수차를 개선해 주는 콤마프리코일(167) 및, 수평편향코일(162)의 둘레면에 장착되어 화면상의 라스트왜곡(이하,디스토션이라 함)을 보정하는 마그네트(161)로 구성된다.In addition, the deflection yoke 160 is mounted on the circumferential surface of the opening A in a state in which the deflection yoke 160 is coupled to the rear end of the cathode ray tube 100 via the ring band 170, and the electron beam 165. ) And a horizontal deflection coil 162 for deflecting the horizontal deflection coil and a vertical deflection coil mounted on the rear side of the horizontal deflection coil 162 through the holder 163 and insulated and deflecting the electron beam 165 in the vertical direction. 164, a ferrite core 166, which is provided on the rear side of the vertical deflection coil 164 to reduce the loss of the magnetic force generated by the current of the coils (162, 164), is mounted on the circumferential surface of the neck portion (B) A comma precoil 167 for improving comma aberration generated by the magnetic field and a magnet 161 mounted on the circumferential surface of the horizontal deflection coil 162 to correct last distortion (hereinafter, referred to as distortion) on the screen. It is composed.

따라서, 편향요크(160)는, 수평편향코일(162)에 15.75KMHz 또는 그 이상의 주파수를 가지는 전류를 흘려보내 전자빔(165)을 수평방향으로 편향시킴과 동시에 수직편향코일(164)에 60Hz의 주파수를 가지는 전류를 흘려보내 전자빔(165)을 수직방향으로 편향시키는 기능을 수행하는 것이다.Accordingly, the deflection yoke 160 sends a current having a frequency of 15.75 KMHz or higher to the horizontal deflection coil 162 to deflect the electron beam 165 in the horizontal direction and at the same time to the vertical deflection coil 164 at a frequency of 60 Hz. By flowing a current having a function to deflect the electron beam 165 in the vertical direction.

또한, 도 3에서와 같이, 수평/수직편향코일(162,164)을 이분할함과 더불어 그 형상을 새들형으로 형성하여, 편향요크(160)의 둘레면에 각각 병렬로 연결한 다음, 톱니파형상의 수평편향전류를 흘려 주어, 핀쿠션형상의 수평편향자계를 형성하는 방법이 제안되어 사용되고 있다.In addition, as shown in FIG. 3, the horizontal / vertical deflection coils 162 and 164 are divided into two, and the shape thereof is formed in a saddle shape, and connected to the circumferential surfaces of the deflection yoke 160 in parallel, and then sawtooth wave shape. A method of forming a pincushion-like horizontal deflection magnetic field by flowing a horizontal deflection current has been proposed and used.

이때, 음극선관(100)의 전자총(155)에서 발사되는 세 개의 전자빔(165) 즉, 적색과 녹색과 청색의 전자빔이 코일(162,164)의 자계영역을 통과하면서 플레밍의 왼손법칙에 의해, 전자빔(165)이 받는 힘이 편향코일의 내면과 전자빔간의 거리의 삼승에 반비례하여 수평방향으로 편향되는 것이다.At this time, the three electron beams 165 emitted from the electron gun 155 of the cathode ray tube 100, that is, the red, green, and blue electron beams pass through the magnetic field regions of the coils 162 and 164, and according to Fleming's left hand law, the electron beam ( 165) is deflected horizontally in inverse proportion to the square of the distance between the inner surface of the deflection coil and the electron beam.

한편, 편향요크(160)는, 전자빔(165)에 별도의 부가회로 및 부가장치를 설치하지 않은 상태에서도 전방패널(110)에서 컨버젼스를 이룰 수 있도록, 수평/수직편향코일(162,164)의 권선분포를 각 부위별(개구부, 중간부, 넥크부)로 조정하는 이른바 셀프컨버젼스형태의 편향요크가 개발되고 있다.On the other hand, the deflection yoke 160 has a winding distribution of the horizontal / vertical deflection coils 162 and 164 so as to achieve convergence in the front panel 110 even without an additional circuit and an additional device installed in the electron beam 165. The so-called self-convergence type of deflection yoke that adjusts to each part (opening part, middle part, neck part) has been developed.

즉, 편향요크(160)에서 세 개의 전자빔(165)이 위치에 따라서 각각 다른 편향력을 경험하도록 구성되어, 예컨대 전자빔(165)의 출발지점인 전자총(155)으로부터 도착지점인 전방패널(화면,110)까지의 각각 다른 거리에서 동일한 지점으로 모아질 수 있도록 하는 방법이 연구중에 있다.That is, the three electron beams 165 in the deflection yoke 160 are configured to experience different deflection forces according to their positions, for example, the front panel (screen, which is the arrival point from the electron gun 155 which is the starting point of the electron beam 165). There is a study on how to collect them at the same point at different distances up to 110).

또한, 수평/수직편향코일(162,164)에 자계를 형성하는 것만으로는 전방패널 (110)의 전면에 전자빔(165)을 완벽하게 편향시키기 어려워 예컨대, 고투자율의 페라이트코어(166)를 사용하여 자계의 귀환경로상에서의 손실을 최소화함으로서 자계의 효율을 높이는 방법이 연구중에 있다.In addition, it is difficult to completely deflect the electron beam 165 on the front of the front panel 110 only by forming a magnetic field on the horizontal / vertical deflection coils 162 and 164, for example, by using a ferrite core 166 having a high permeability. A method of increasing the efficiency of the magnetic field by minimizing the loss on the return path of the furnace is under study.

그런데, 벤트업타입의 수평/수직편향코일(162,164)은 동선의 소요량 감소에 따른 재료비가 감소되어 제조비용이 절감됨은 물론 페라이트코어를 사용하여 미스컨버젼스의 보정작업이 용이한 장점은 있으나, 머슬타입의 수평/수직편향코일에 비교하여 볼 때 상대적으로 편향감도가 저하되는 문제점이 있었다.However, the vent-up type horizontal / vertical deflection coils (162, 164) have the advantage that the material cost is reduced due to the reduction of copper wire requirements, and the manufacturing cost is reduced, and the correction work of misconvergence using a ferrite core is easy. Compared with the horizontal / vertical deflection coils, the deflection sensitivity was relatively low.

이때, 도 3에서와 같이, 벤트업타입에서 편향감도의 증대수단으로서, 수평/수직편향코일(162,164)의 양단부를 이루는 직선플린지(180)의 길이를 연장하는 방법이 있지만, 직선플린지(180)는 음극선관(100)의 네크부(B)로 삽입되어 고정되는 상태로서 길이연장이 매우 어려운 문제점이 있었다.At this time, as shown in Figure 3, as a means of increasing the deflection sensitivity in the vent-up type, there is a method of extending the length of the straight fringe 180 forming both ends of the horizontal / vertical deflection coils (162, 164), 180 is a state in which the length of the cathode ray tube 100 is inserted into and fixed to the neck portion B and is very difficult to extend.

그리고, 직선플린지(180)의 길이를 연장하여 음극선관(100)의 네크부(B)로 삽입하여 고정시키는 경우, 네크부(B)내에서 전자총(155)의 메인렌즈(미도시)와 직선플린지(180)의 연장부가 상호 간섭되는 문제점이 있었다.In addition, in the case where the length of the straight fringe 180 is extended to be inserted into the neck portion B of the cathode ray tube 100 and fixed, the main lens (not shown) of the electron gun 155 in the neck portion B is fixed. There was a problem that the extensions of the straight fringe 180 interfere with each other.

이에, 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 편향코일의 형상을 변경하여 편향감도를 향상시킴과 더불어 디스토션의 보정에따른 작업공수를 절감시킬 수 있도록 된 음극선관용 편향요크를 제공하는 데에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, to improve the deflection sensitivity by changing the shape of the deflection coil and to reduce the work maneuver according to the correction of the distortion of the cathode ray tube deflection yoke The purpose is to provide.

상기한 바의 목적을 달성하기 위한 본 발명은, 개구부의 둘레면에 장착되어 전자빔을 수평방향으로 편향시키는 수평편향코일과, 수평편향코일의 후방측에 홀더를 통해 절연상태로 고정되어 전자빔을 수직방향으로 편향시키는 수직편향코일, 수직편향코일의 후방측에 구비되어 코일의 전류에 의해 발생하는 자기력을 손실을 줄여주는 페라이트코어로 이루어진 편향요크에 있어서, 수평/수직편향요크의 네크측플린지 또는 개구측플린지의 두께를 원주방향을 따라 서로 다르게 하여 경사부를 형성시킨 것을 특징으로 한다.The present invention for achieving the above object, the horizontal deflection coil mounted on the circumferential surface of the opening to deflect the electron beam in the horizontal direction, and fixed to the rear side of the horizontal deflection coil through the holder in an insulated state to vertically In the deflection yoke made of a vertical deflection coil deflecting in the direction, a ferrite core provided on the rear side of the vertical deflection coil to reduce the loss of magnetic force generated by the current of the coil, the neck side fringe of the horizontal / vertical deflection yoke or It characterized in that the inclined portion is formed by varying the thickness of the opening side fringe along the circumferential direction.

The ring band 170 is formed at the rear end of the cathode ray tube 100. In the coupled state through, the horizontal deflection coil 162 mounted on the circumferential surface of the opening A and deflecting the electron beam 165 in the horizontal direction, and the holder 163 on the rear side of the horizontal deflection coil 162. Ferrite core that is fixed to the insulating state through the vertical deflection coil 164, the vertical deflection coil 164 to deflect the electron beam in the vertical direction to reduce the loss of magnetic force generated by the current of the coils (162, 164) 166, the neck side fringe 10 of the horizontal / vertical deflection yoke 162, 164 in the deflection yoke 160 made of a magnet 161 mounted on the circumferential surface of the opening A to correct the distortion on the screen. Alternatively, the thickness of the opening side fringes 20 may be different from each other along the circumferential direction. The inclined portion 30 is formed.

먼저, 본 발명의 구성요소 중 음극선관(100)의 전방패널(110)과 형광면(120)과 섀도우마스크(130)와 펀넬(140)과 네크부(150)와 편향요크(160)와 링밴드(170)는 종래기술과 기능상 동일하므로 자세한 설명은 생략하고, 다만 편향요크(160)의 둘레면에 장착되어 전자빔(165)을 수평방향 또는 수직방향으로 편향시키는 코일 (162,164)의 형상이 변경된 것에 차이점이 포함되어 있다.First, the front panel 110, the fluorescent surface 120, the shadow mask 130, the funnel 140, the neck portion 150, the deflection yoke 160 and the ring band of the cathode ray tube 100 of the components of the present invention Since 170 is functionally the same as the prior art, a detailed description thereof will be omitted, but the shape of the coils 162 and 164 mounted on the circumferential surface of the deflection yoke 160 to deflect the electron beam 165 in the horizontal direction or the vertical direction is changed. Differences are included.

이때, 수평편향요크(162)와 수직편향요크(164)는 각각 상하 대칭하는 형상으로 이분할되어 형성됨과 더불어 그 외관이 새들형상으로 형성된 것으로서, 그 몸체의 일단부에 네크측플린지(10)가 구비됨과 더불어 그 타단부에 개구측플린지(20)가 각각 형성되어 있다.At this time, the horizontal deflection yoke 162 and the vertical deflection yoke 164 are each divided into a vertically symmetrical shape and the appearance is formed in a saddle shape, the neck side fringe 10 at one end of the body And opening side fringes 20 are formed at the other end thereof.

그리고, 네크측플린지(10)와 개구측플린지(20)는, 그 내벽에 중심부로부터 외곽방향을 향해 또는 외곽으로부터 중심부를 향해 오목 또는 볼록한 형상을 갖는 경사부(30)가 형성되어, 즉 네크측플린지(10)와 개구측플린지(20)의 내벽에 연장부가 형성된 것과 동일한 역할을 수행한다.Then, the neck side fringe 10 and the opening side fringe 20 are formed on the inner wall with an inclined portion 30 having a concave or convex shape from the center toward the outward direction or from the outside toward the center. It performs the same role as the extension portion is formed on the inner wall of the neck side fringe 10 and the opening side fringe 20.

이때, 네크측플린지(10)와 개구측플린지(20)는, 그 내벽에 최대두께(a)와 최소두께(b)가 0.5 ≤(b/a) ≤0.7의 수식을 만족하는 경사부(30)가 형성되는데, 0.7이상일 경우 편향감도의 효율이 감소되고 0.5이하일 경우에는 플린지 끝부분의 코일수가 중앙부분보다 너무 적게 권선되어 정상적인 편향자계의 형성이 어려워진다.At this time, the neck side fringe 10 and the opening side fringe 20 have an inclined portion whose maximum thickness (a) and minimum thickness (b) satisfy a formula of 0.5≤ (b / a) ≤0.7 on the inner wall thereof. If 30 or more is formed, the efficiency of the deflection sensitivity is reduced when it is 0.7 or more, and when it is 0.5 or less, the number of coils at the tip of the fringe is wound less than the center part, making it difficult to form a normal deflection magnetic field.

이때, 네크측/개구측플린지(10,20)에서 경사부(30)의 경사각도(β)를, 수평측의 권형기준선(40)을 중심으로 0∼85도의 각도범위로 경사지게 형성하여 자계의 손상을 최소화함은 물론 자기력을 증대시킴이 바람직하다. 이는 핀돌출방식의 새들형 편향코일에서 창부의 폭을 설계하는 경우 85도 이상에서는 1차자계의 크기가 매우 작아지므로 대부분 상기의 각도내에서 성형되도록 편향코일을 설계한다.At this time, the inclination angle β of the inclined portion 30 in the neck side / opening side fringes 10 and 20 is formed to be inclined in an angle range of 0 to 85 degrees with respect to the horizontal reference line 40 on the horizontal side. In addition to minimizing damage, it is desirable to increase the magnetic force. This is because when the width of the window is designed in the saddle type deflection coil of the pin protrusion type, the size of the primary magnetic field becomes very small at 85 degrees or more, so the deflection coil is designed to be molded within the above angle.

이하, 본 발명에 따른 실시예를 첨부된 예시도면을 참고로하여 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

먼저, 편향요크(160)의 둘레면에 홀더(163)를 통해 장착되는 수평편향코일 (162)에 15.75KMHz 또는 그 이상의 주파수를 가지는 전류를 흘려보내 전자빔(165)을 수평방향으로 편향시킴과 동시에 수직편향코일(164)에 60Hz의 주파수를 가지는 전류를 흘려보내 전자빔(165)을 수직방향으로 편향시킨다.First, a current having a frequency of 15.75 KMHz or higher is sent to the horizontal deflection coil 162 mounted on the circumferential surface of the deflection yoke 160 via the holder 163 to deflect the electron beam 165 in the horizontal direction. A current having a frequency of 60 Hz is flowed through the vertical deflection coil 164 to deflect the electron beam 165 in the vertical direction.

이때, 수평/수직편향코일(162,164)의 권선분포가 네크측/개구측플린지(10, 20)에 형성된 경사부(30)를 통해 부위별(개구부, 중간부, 네트부)로 조정되어 바렐 혹은 핀쿠션형의 자계를 형성하므로, 각각의 전자빔(165)이 부위별로 각각 다른 편향력을 갖게 되는 것이다.At this time, the winding distribution of the horizontal / vertical deflection coils (162, 164) is adjusted for each part (opening part, middle part, net part) through the inclined part 30 formed in the neck side / opening side fringes 10, 20 and barrel. Alternatively, since a pincushion type magnetic field is formed, each electron beam 165 has a different deflection force for each part.

이때, 전자빔(165)이 각 부위별로 서로 다른 편향력을 보여, 예컨대 전자빔(165)이 출발지점인 전자총(155)으로부터 도착지점인 전방패널(화면,110)까지의 각각 다른 거리에서 동일한 지점으로 모아지므로, 편향요크(160)의 편향감도가 증대됨은 물론 디스토션의 보정작업이 용이해지는 것이다.At this time, the electron beam 165 shows a different deflection force for each part, for example, the electron beam 165 at the same point at different distances from the electron gun 155 as the starting point to the front panel (screen 110) as the arrival point. Since the deflection yoke 160 is increased, the deflection sensitivity of the deflection yoke 160 is increased, and the distortion correction operation is facilitated.

따라서, 벤트업타입의 수평/수직편향코일(162,164)의 전장길이를 변화시키지않은 상태에서도 단지 네크측/개구측플린지(10,20)의 동선이 순차적으로 권선되게 함으로써 편향코일(162,164)의 플린지가 연장되는 효과가 있으므로, 도 6에서와 같이, 자계의 효율이 증대되어 벤트업타입의 편향코일을 이용하여 편향감도 및 디스토션의 보정작업이 가능해지는 것이다.Accordingly, the deflection coils 162 and 164 are wound by sequentially winding copper wires of the neck side / opening side fringes 10 and 20 without changing the full length of the vent up type horizontal / vertical deflection coils 162 and 164. Since the fringe is extended, as shown in FIG. 6, the efficiency of the magnetic field is increased, and the deflection sensitivity and the distortion correction operation can be performed using the vent-up type deflection coil.

이상에서 설명한 바와 같이 본 발명에 따른 음극선관용 편향요크에 의하면, 수평/수직편향요크에 별도의 부가장치나 부가회로를 구성하지 않은 상태에서도 네크측/개구측플린지가 연장되므로, 편향요크의 편향감도가 향상됨은 물론 디스토션의 보정작업이 용이해질 뿐만 아니라 음극선관의 제품품질이 향상되어 가격 경쟁력의 측면에서 유리한 효과가 있는 것이다.As described above, according to the deflection yoke for the cathode ray tube according to the present invention, since the neck side / opening side fringe is extended even when a horizontal / vertical deflection yoke is not provided with an additional device or additional circuit, the deflection sensitivity of the deflection yoke is increased. In addition to improving the distortion, the correction operation of the distortion is not only easy, the product quality of the cathode ray tube is improved, which is advantageous in terms of price competitiveness.
