Abstract
본 고안은 브라운관 내에 새도우마스크가 용접고정된 프레임과 결합 설치되면서 전자빔에 대한 외부지자계의 영향을 차폐하여 브라운관의 색순도를 향상시키는 인너시일드(Inner Shield)에 관한 것이다.The present invention relates to an inner shield that improves the color purity of the CRT by shielding the influence of the external geomagnetic field on the electron beam while the shadow mask is installed in the CRT with the welded frame.
종래, 소정형상의 두 몸체를 결합하여 된 인너시일드는 두 몸체의 결합력이 극히 약하여 외부의 약한 충격으로도 두 몸체가 분리될 뿐만 아니라 전자총에서 방출된 전자비임이 인너시일드에 충돌하여 발생하는 고열에 의해 두 몸체의 결합부위가 분리되어 외부의 지자계를 효과적으로 차단하지 못하는 문제점이 있었다.Conventionally, an inner seal formed by combining two bodies of a predetermined shape has a very weak coupling force between the two bodies, so that not only the two bodies are separated by a weak external shock, but also a high temperature generated by the electron beam emitted from the electron gun colliding with the inner shield. There is a problem in that the coupling portion of the two body is separated by the effective blocking of the external geomagnetic field.
그래서 본 고안의 목적은 이러한 종래의 문제점을 감안하여 안출한 것으로 인너시일드를 구성하는 두 몸체의 결합력을 극대화시킴으로써 외부에서 강한 충격이 인너시일드에 미치거나 전자비임 충돌로 인한 열변형이 인너시일드에 발생하더라도 두 몸체가 분리되지 않도록 한 인너시일드 구조를 제공함에 있으며, 이러한 목적을 달성하기 위하여 본 고안은 제1몸체의 양측 단부의 적소에 소정의 결합공을 천공하는 한편, 전술한 제1몸체와 대응하는 제2몸체의 양측 단부에 제1몸체의 결합공과 대응하는 결합편을 형성하여 전술한 두 몸체를 결합하여서 된 것이다.Therefore, the object of the present invention was devised in view of such a conventional problem, and by maximizing the coupling force of the two bodies constituting the inner shield, the strong impact from the outside impacts the inner shield or the thermal deformation caused by the electron beam collision. The present invention provides an inner seal structure that prevents two bodies from being separated even if they occur in the shield. To achieve the above object, the present invention drills a predetermined coupling hole in place at both ends of the first body, The first body is formed by joining the two bodies described above by forming a coupling piece corresponding to the coupling hole of the first body at both ends of the second body corresponding to the first body.

본 고안은 브라운관 내에 새도우마스크가 용접고정된 프레임과 결합 설치되면서 전자빔에 대한 외부지자계의 영향을 차폐하여 브라운관의 색순도를 향상시키는 인너시일드(Inner Shield)에 관한 것이다.The present invention relates to an inner shield that improves the color purity of the CRT by shielding the influence of the external geomagnetic field on the electron beam while the shadow mask is installed in the CRT with the welded frame.
일반적으로 인너시일드는 브라운관 내에 고정지지된 프레임과 결합하여 전자총에서 방출된 전자빔이 외부지자계의 영향을 받지 않고 소망하는 형광면에 정확히 랜딩되도록 함으로써, 칼라브라운관의 색순도가 향상되도록 한 것이며, 통상적인 인너시일드 구조는 두개의 박판을 소정형상으로 프레스가공한 후 이 두 구조물을 결합하여서 된 것인데, 종래의 인너시일드 결합구조가 도면 제1도에 도시된 바와 같이 외부지자계를 상쇄시킬 목적으로 수개의 개공(11)이 천공된 제1몸체(10)의 양측 단부에서 상방 및 측방으로 결합홈(12)(13)을 각각 형성하는 한편, 전술한 제1몸체(10)와 대향형성된 제2몸체(20)의 양측 단부에는 제1몸체(10)의 각 결합홈(12)(13)에 대응절첩되는 결합편(22)(23)을 각각 형성하였던바, 이와 같이 결합된 종래의 인너시일드(1)는 두 몸체(10)(20)의 결합력이 극히 약하여 외부의 약한 충격으로도 두 몸체(10)(20)가 분리될 뿐만 아니라 전자총(미도시)에서 방출된 전자비임이 인너시일드(1)에 충돌하여 발생하는 고열에 의해 두 몸체(10)(20)의 결합부위가 분리되어 외부의 지자계를 효과적으로 차단하지 못하는 문제점이 있었다.In general, the inner seal is combined with a frame fixed in the CRT so that the electron beam emitted from the electron gun can be accurately landed on a desired fluorescent surface without being affected by an external geomagnetic field, thereby improving color purity of the color CRT. The seal structure is obtained by pressing two thin plates into a predetermined shape and then joining the two structures. A conventional inner seal coupling structure can be used to offset the external geomagnetic field as shown in FIG. Two openings 11 forming coupling grooves 12 and 13 upwardly and laterally at both end portions of the first body 10 which are perforated, respectively, and the second body facing the first body 10 described above. At both ends of the 20, coupling pieces 22 and 23 corresponding to each of the coupling grooves 12 and 13 of the first body 10 were formed, respectively. (1) two bodies (10) Coupling force of (20) is extremely weak, not only the two bodies (10, 20) are separated by a weak external shock, but also a high temperature generated by the electron beam emitted from the electron gun (not shown) collide with the inner shield (1) Thereby, the coupling portions of the two bodies 10 and 20 are separated, and thus there is a problem in that the external geomagnetic field is not effectively blocked.
그래서 본 고안의 목적은 이러한 종래의 문제점을 감안하여 안출한 것으로 인너시일드를 구성하는 두 몸체의 결합력을 극대화시킴으로써 외부에서 강한 충격이 인너시일드에 미치거나 전자비임 충돌로 인한 열변형이 인너시일드에 발생하더라도 두 몸체가 분리되지 않도록 한 인너시일드 구조를 제공함에 있으며, 이러한 목적을 달성하기 위하여 본 고안은 제1몸체의 양측 단부의 적소에 소정의 결합공을 천공하는 한편, 전술한 제1몸체와 대응하는 제2몸체의 양측 단부에 제1몸체의 결합공과 대응하는 결합편을 형성하여 전술한 두 몸체를 결합하여서 된 것이다.Therefore, the object of the present invention was devised in view of such a conventional problem, and by maximizing the coupling force of the two bodies constituting the inner shield, the strong impact from the outside impacts the inner shield or the thermal deformation caused by the electron beam collision. The present invention provides an inner seal structure that prevents two bodies from being separated even if they occur in the shield. To achieve the above object, the present invention drills a predetermined coupling hole in place at both ends of the first body, The first body is formed by joining the two bodies described above by forming a coupling piece corresponding to the coupling hole of the first body at both ends of the second body corresponding to the first body.
이하, 본 고안의 일실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 따른 인너시일드의 요부 분해사시도이고, 제3도는 본 고안에 따른 인너시일드의 요부를 발췌도시한 평면도로서, 외부지자계를 상쇄시킬 목적으로 수개의 개공(11)이 천공된 제1몸체(10)의 양측 단부에서 상부 및 측부 적소에 소정길이의 결합공(12')(13')을 각각 형성하는 한편, 전술한 제1몸체(10)와 동일형상으로 대향형성된 제2몸체(20)의 양측 단부에는 제1몸체(10)의 각 결합공(12')(13')에 대응절첩되도록 소정길이의 결합편(22)(23)을 각각 형성한다.Figure 2 is an exploded perspective view of the main portion of the inner shield according to the present invention, Figure 3 is a plan view showing the main portion of the inner shield according to the present invention, several openings 11 for the purpose of offsetting the external geomagnetic field The coupling holes 12 'and 13' of predetermined lengths are respectively formed at upper and side locations at both end portions of the perforated first body 10, and are formed to face the same shape as the first body 10 described above. At both ends of the second body 20, coupling pieces 22 and 23 of predetermined length are formed so as to correspond to respective coupling holes 12 'and 13' of the first body 10, respectively.
위에서 설명한 인너시일드(1)의 구조는 본 고안의 한 가능한 실시예에 불과하며, 예컨대 제1몸체(10)의 양측 단부에 수직으로 길게 결합공을 형성한 후 제1몸체(10)와 동일형상으로 대향형성된 제2몸체(20)의 양측 단부에는 제1몸체(10)의 결합공에 대응절첩되도록 소정길이의 결합편을 수직형성하여 전술한 두 몸체(10)(20)를 결합하여도 무방하며, 또한 제1몸체(10)에 마련된 결합공(12')(13')과 제2몸체(20)에 마련된 결합편(22)(23)의 형상은 앞서 설명한 본 고안의 범위 내에서 얼마든지 그 변형은 가능하다.The structure of the inner shield 1 described above is only one possible embodiment of the present invention, and for example, the same shape as that of the first body 10 after forming a coupling hole vertically long at both ends of the first body 10. Even when the two bodies 10 and 20 are coupled to each other by vertically forming a coupling piece having a predetermined length so as to correspond to the coupling hole of the first body 10 at both end portions of the second body 20 facing each other in a shape. The shape of the coupling holes 12 'and 13' provided in the first body 10 and the coupling pieces 22 and 23 provided in the second body 20 may be within the scope of the present invention. As many variations are possible.
미설명부호 21은 개공이다.Reference numeral 21 is an opening.
이와 같이 본 고안은 제2도에 도시한 바와 같이 제1몸체(10)의 양측 단부로 형성된 상부와 측부의 두 결합공(12')(13')에 제2몸체(20)의 양측 단부로 마련된 결합편(22)(23)을 삽입한 후 이들을 일방향으로 절첩하여 전술한 두 몸체(10)(20)를 결합함으로써, 외부에서 강한 충격이 두 몸체(10)(20)가 결합완성된 인너시일드(1)에 미치거나 전자총에서 방출된 전자비임의 충돌로 인한 열변형이 인너시일드(1)에 발생하여 다소 변형된다 하더라도 이의 두 몸체(10)(20)가 분리되지 않도록 한 효과가 있다.As described above, the present invention is provided with both end portions of the second body 20 in two coupling holes 12 'and 13' of the upper and side portions formed as both end portions of the first body 10, as shown in FIG. By inserting the provided coupling pieces 22 and 23 and then folding them in one direction to combine the two bodies (10, 20) described above, a strong impact from the outside, the two bodies (10, 20) is completed inner Although thermal deformation due to collision of the electron beam emitted from the electron gun or emitted from the electron gun occurs to the inner shield 1 and is somewhat deformed, the effect of preventing the two bodies 10 and 20 from being separated have.
