본 고안은 칼라브라운관의 콘택트스프링에 관한 것으로, 특히 일단에 인너실드를 프레임에 고정하는 클립부를 일체로 성형하므로써 콘택트스프링을 인너실드에 용접할 필요가 없는 클립겸용 콘택트스프링에 관한 것이다.The present invention relates to a contact spring of a color-brown tube, and more particularly, to a combined contact spring that does not need to weld the contact spring to the inner shield by integrally molding the clip portion fixing the inner shield to the frame.

일반적으로 칼라브라운관의 콘택트스프링은 전자총에서 방출된 전자비임이 색선별 기능의 섀도우 마스크를 통해 형광체에 교차될 때 남아있게 되는 잔류전자를 외부로 방출시키도록 교량역활을 한다.In general, the contact spring of the color-brown tube acts as a bridge to release the residual electrons remaining when the electron beam emitted from the electron gun is crossed to the phosphor through the shadow mask having the color screening function.

잔류전자는 화면상태를 심하게 아른거리게 하며, 화면에서 밝고 어두운 원띠모양이 형성되어 발광정도가 일정치 않게 되고, 또한 섀도우 마스크를 통과하는 비임경로를 굴절시키는 리그루웁(Regrouping)현상을 유발시킨다.Residual electrons cause the screen to stutter heavily, and bright and dark circles form on the screen, resulting in uneven light emission, and also causing regrouping, which deflects the beam path through the shadow mask.

이러한 잔류전자를 제거하기 위해 종래에는 제1도에 도시한 바와 같이 패널(1)의 내벽에 일체로 고정시킨 스터드핀(7)과, 그 패널(1)의 형광막(4)위에 도포한 알루미늄막(5)사이로 띠상으로 된 도전성의 흑연막(6)을 형성하고, 섀도우 마스크(9)를 지지하는 프레임(10)은 후크스프링(8)을 통해 상기 스터드핀(7)에 고정되며, 브라운관내의 인너실드(12)는 상기 프레임(10)에 클립(11)으로 고정한 다음, 콘택트스프링(13)의 일측을 스폿트용접(14)으로 고정시키고, 상기 콘택트스프링(13)의 타측은 그 절곡된 부위로 하여금 펀널(2) 내벽에 도포한 흑연막(15)과 탄성적으로 접촉되도록 구성하였다.In order to remove such residual electrons, as shown in FIG. 1, a stud pin 7 fixed integrally to the inner wall of the panel 1 and aluminum coated on the fluorescent film 4 of the panel 1 are conventionally used. A band-shaped conductive graphite film 6 is formed between the films 5, and the frame 10 supporting the shadow mask 9 is fixed to the stud pins 7 through the hook springs 8, and the CRT tube The inner shield 12 is fixed to the frame 10 with a clip 11, and then, one side of the contact spring 13 is fixed by spot welding 14, and the other side of the contact spring 13 is bent. The formed portions were elastically contacted with the graphite film 15 applied to the inner wall of the funnel 2.

이와 같은 종래의 구성에 의해서 섀도우 마스크(9)에서 충돌하고 남은 잔류전자는 섀도우 마스크(9)→프레임(10)→콘택트스프링(13)→흑연막(15)으로 흐르고, 스크린 형광막(4)에서 충돌하고 남은 잔류전자는 형광막(4)→알루미늄막(5)→흑연막(6)→스터드핀(7)→후크스프링(8)→프레임(10)→콘택트스프링(13)→흑연막(15)을 통해 스크린 형광막(4)과, 섀도우 마스크(9)에서 각각으로 충돌하여 남은 잔류전자를 외부로 방출시킨다.The remaining electrons collided in the shadow mask 9 by such a conventional configuration flow from the shadow mask 9 to the frame 10 to the contact spring 13 to the graphite film 15 and to the screen fluorescent film 4. The remaining electrons collided in the fluorescent film were fluorescent film (4), aluminum film (5), graphite film (6), stud pin (7), hook spring (8), frame (10), contact spring (13), and graphite film. The remaining electrons collided with each other through the screen fluorescent film 4 and the shadow mask 9 through 15 are emitted to the outside.

이와 같이, 콘택트스프링(13)은 섀도우 마스크(9), 프레임(10) 및 인너실드(12)의 잔류전자를 외부로, 흑연막(6)은 스크린 형광막(4)의 잔류전자를 알루미늄막(5)을 통하여 흑연막(6), 후크 스프링(8), 프레임(10) 및 콘택트스프링(13)으로 연결되어 외부로 방출시키는 교량역할을 하였던 것이다. 그러나, 이러한 콘택트스프링(13)을 고정시키기 위해서는 프레임(10)과 인너실드(12)을 클립(11)을 고정한 상태에서 콘택트스프링(13)을 부착하기 위해 적어도 4∼6점 정도의 스폿트용접(14)을 수행하게 됨으로써, 용접시에 다량으로 발생하는 불티가 브라운관 내에 잔존하게 되면서 섀도우 마스크(9)의 일부구멍(전자 비임이 통과하는 구멍)을 막는 현상이 일어나는 등 많은 문제점이 있었다.In this way, the contact spring 13 sends the residual electrons of the shadow mask 9, the frame 10 and the inner shield 12 to the outside, and the graphite film 6 transfers the residual electrons of the screen fluorescent film 4 to the aluminum film. It was connected to the graphite film 6, the hook spring 8, the frame 10 and the contact spring 13 through (5) to serve as a bridge to release to the outside. However, in order to fix the contact spring 13, spot welding of at least 4 to 6 points is required to attach the contact spring 13 to the frame 10 and the inner shield 12 while the clip 11 is fixed. By performing (14), there were many problems such as a phenomenon in which a large amount of bleeding generated during welding remained in the CRT and a part of the shadow mask 9 (the hole through which the electron beam passes) occurred.

더구나, 종래에는 프레임(10)과 인너실드(12)를 클립(11)만으로 고정하므로써, 충격이 가해지게 되면 프레임(10)과 인너실드(12)에 간격이 생겨서, 잔류전자를 외부로 방출시키는 데에 문제가 있었고, 또한 콘택트스프링(13)의 탄성이 변형되는 경우, 그 기능을 수행하는데 어려움이 많았다.Moreover, conventionally, by fixing the frame 10 and the inner shield 12 only with the clip 11, when an impact is applied, a gap is generated in the frame 10 and the inner shield 12, thereby releasing residual electrons to the outside. There was a problem, and when the elasticity of the contact spring 13 was deformed, it was difficult to perform the function.

본 고안은 이에 따라 안출된 것으로, 그 목적은 용접시 발생하는 불티가 섀도우 마스크의 구성을 막는 현상을 방지할 수 있도록 인너실드에 콘택트스프링을 용접하는 공정을 없앨 수 있는 클립겸용 콘택트스프링을 제공하는 것이다.The present invention has been devised accordingly, and an object thereof is to provide a combined contact spring that can eliminate the process of welding the contact spring to the inner shield to prevent the phenomenon that the spark generated during welding prevents the configuration of the shadow mask. will be.

본 고안의 다른 목적은 일단과 타단에 각각 형성한 클립부와 접촉부가 탄성지지되므로서 충격에 견딜 수 있는 클립겸용 콘택트스프링을 제공하는 것이다.Another object of the present invention is to provide a combined contact spring that can withstand impact while being elastically supported by the clip and contact portions formed at one end and the other end, respectively.

이러한 목적을 달성하기 위한 수단으로서, 본 고안은 일단에 프레임과 인너실드를 결합하는 클립부를 일체로 성형하고, 타단에 흑연막과의 접촉부를 형성하여 절곡한 콘택트스프링과 이 콘택트스프링의 타단이 인너실드의 측면에 형성된 구멍에 삽입되어 클립부와 접촉부가 탄성지지되는 것을 특징으로 하는 클립겸용 콘택트스프링을 제안한다.As a means for achieving the above object, the present invention is formed by integrally forming a clip portion for coupling the frame and the inner shield at one end, and forming a contact portion with the graphite film at the other end and the other end of the contact spring is inner It is proposed a combined contact spring characterized in that the clip portion and the contact portion is elastically supported by being inserted into a hole formed in the side of the shield.

이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

제2도는 본 고안에 따른 콘택트스프링을 나타내는 것으로, 도시된 바와 같이 본 고안의 콘택트스프링(20)은 일단에 클립부(21)를 일체로 성형하고, 하단에 접촉부(22)를 형성하여 ㄱ자 형상으로 절곡한 것이다.2 is a view showing a contact spring according to the present invention, as shown in the contact spring 20 of the present invention integrally molded with a clip portion 21 at one end, forming a contact portion 22 at the bottom of the L-shape Bent into.

이와 같이 구성된 본 고안의 콘택트스프링(20)은 제3도에 도시된 바와 같이, 클립부(21)는 클립형상으로, 프레임(10)과 인너실드(30)를 결합고정하며, 접촉부(22)는 둥글게 라운드처리된 오목한 형상으로, 인너실드(30)의 측면에 형성된 구멍(31)을 통해 삽입되어, 흑연막(15)과 접촉한다. 이때, 클립부(21)와 접촉부(22)는 탄성적으로 지지된다. 도면중 미설명부호들은 종래의 브라운관의 내부구조와 동일하므로 그 상세한 설명은 생략한다.As illustrated in FIG. 3, the contact spring 20 of the present invention configured as described above has a clip portion 21 in a clip shape, and fixes the frame 10 and the inner shield 30 to each other, and the contact portion 22. Is a rounded concave shape, and is inserted through the hole 31 formed in the side surface of the inner shield 30 to contact the graphite film 15. At this time, the clip portion 21 and the contact portion 22 is elastically supported. Unexplained reference numerals in the drawings are the same as the internal structure of the conventional CRT, so a detailed description thereof will be omitted.

이와 같이 구성된 본 고안의 클립겸용 콘택트스프링은 먼저 패널(1)의 내측면에 형광막(4), 알루미늄막(5) 및 흑연막(6)을 순차적으로 도포한 다음, 스터드핀(7)을 고정한다. 이어 섀도우 마스크(9)와 후크 스프링(8)을 프레임(10)에 일체로 조립한 후 인너실드(30)에 형성된 구멍(31)에 콘택트스프링(20) 타단의 접촉부(22)를 끼워 넣은 다음, 프레임(10)과 인너실드(30)에 콘택트스프링(20)의 일단에 형성한 클립부(21)를 끼워서 고정하면, 콘택트스프링(20) 타단의 접촉부(22)가 펀넬(2)내측면의 흑연막(15)에 탄성적으로 접촉한다.The clip-type contact spring of the present invention configured as described above is first coated with a fluorescent film (4), an aluminum film (5) and a graphite film (6) sequentially on the inner surface of the panel (1), and then the stud pin (7) Fix it. After assembling the shadow mask 9 and the hook spring 8 integrally with the frame 10, the contact 22 of the other end of the contact spring 20 is inserted into the hole 31 formed in the inner shield 30. When the clip portion 21 formed at one end of the contact spring 20 is fixed to the frame 10 and the inner shield 30, the contact portion 22 at the other end of the contact spring 20 becomes the inner side of the funnel 2. Is elastically in contact with the graphite film 15.

한편, 이와 같이 인너실드(30)와 프레임(10)을 조립한 상태에서 후크 스프링(8)에 천공된 체결공(도시하지 않음)을 스터드핀(7)에 맞추어서 결합한다.On the other hand, in the state in which the inner shield 30 and the frame 10 are assembled in this way, the coupling holes (not shown) drilled in the hook spring 8 are coupled to the stud pins 7.

상기한 방법으로 조립된 브라운관의 동작시 형광면(4)에서 충돌하고 남은 잔류전자는 알루미늄막(5)→흑연막(6)→스터드핀(7)→후크 스프링(8)→콘택트스프링(20)→흑연막(15)으로 유도되고, 섀도우 마스크(9)에서 형성된 잔류전자는 프레임(10)→콘택트스프링(20)→흑연막(15)으로 유도되어 외부로 방출되는 것이다.The remaining electrons collided on the fluorescent surface 4 during operation of the CRT assembled in the above-described manner are aluminum film 5 → graphite film 6 → stud pin 7 → hook spring 8 → contact spring 20. → residual electrons formed in the shadow film 9 are guided to the frame 10 → contact spring 20 → graphite film 15 and are emitted to the outside.

이상 설명한 바와 같이 본 고안에 의하면, 콘택트스프링의 일단에 클립부를 일체로 성형하므로서, 콘택트스프링을 프레임에 용접할 필요가 없고, 콘택트스프링의 클립부와 접촉부가 탄성을 받게 되므로 충격이 가해진다 하더라도 프레임과 인너실드의 결합이 확실해지므로 브라운관의 품위를 향상하는 효과가 있다.As described above, according to the present invention, it is not necessary to weld the contact spring to the frame by integrally molding the clip part at one end of the contact spring, and the clip part and the contact part of the contact spring are elastic, so even if the frame is subjected to impact Since the combination of and inner shield is sure, there is an effect of improving the quality of the CRT.
