본 발명은 칼브라운관의 콘택트에 관한 것으로 특히 외부 충격에 의하여 콘택트(Contact)가 움직여 발생하는 쇼크 노이즈(Shook noise)를 줄일 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact of a knife-brown tube, and in particular, to reduce the shock noise caused by the movement of a contact due to an external impact.
종래의 칼라브라운관은 제1도와 같이 전자총(1)이 내재된 넥트(2)와, 상기 넥크(2)가 접속되고 내,외장 흑연이 도포된 펀넬(3)과 상기 펀넬(3)과 접속됨과 아울러 형광체가 도포된 새도우 마스크(4)와, 상기 새도우 마스크(4)가 결합된 프레임(4')이 결합되는 판넬(5)과, 상기 프레임(4')과 패널(5)을 접속하는 스터드핀(5')과, 상기 프레임(4')과 패널(3)에 도포된 흑연막을 접속시키는 콘택트(6)가 구성되었다.The conventional color-brown tube is connected to the neck 2 having the electron gun 1 embedded therein, the funnel 3 to which the neck 2 is connected, and to which the internal and external graphite is applied, and the funnel 3, as shown in FIG. In addition, a shadow mask 4 coated with a phosphor, a panel 5 to which the frame 4 'to which the shadow mask 4 is coupled are coupled, and a stud connecting the frame 4' and the panel 5 to each other. The contact 6 which connects the pin 5 ', the said frame 4', and the graphite film apply | coated to the panel 3 was comprised.
그리고, 전자총(1)에 결합되는 소켓(7)은 회로(8)의 일단을 연결하는 것이고, 회로(8)의 타단은 펀넬(3)에 형성된 OM 노드캡(9)과 연결되었다.The socket 7 coupled to the electron gun 1 connects one end of the circuit 8, and the other end of the circuit 8 is connected to the OM node cap 9 formed in the funnel 3.
그리고, 상기 콘택트(6)는 제2도의 (나)와 같이 판스프링으로 구성되어 일단에 핀홀(10)이 형성된 프레임(4')에 핀결합되고, 그 선단은 탄성력에 의해 펀넬(3)내에 접촉되도록 구성되었다.Then, the contact 6 is composed of a leaf spring as shown in (b) of FIG. 2 and pinned to a frame 4 'having a pinhole 10 formed at one end thereof, the tip of which is in the funnel 3 by an elastic force. Configured to be contacted.
이와 같이 구성된 칼라브라운관의 회로(8)에서 발생된 신호는 전자총(1)에 전달되고, 상기 전자총(1)에서는 신호를 받아 열전자를 전자빔(10)으로 접속하여 스크린에 주사한다.The signal generated in the circuit 8 of the color-brown tube configured as described above is transmitted to the electron gun 1, which receives the signal and connects the hot electrons to the electron beam 10 to scan the screen.
스크린에 주사되는 전자빔은 새도우 마스크(4)에 도포된 형광체를 발광시키고, 판넬(5)에 도포된 알루미늄막과 스터드핀(5')과 콘택트(6)과 펀넬(3)에 내장된 흑연막을 거쳐서 애노드캡(9)으로 빠져나갔다.The electron beam scanned on the screen emits phosphors applied to the shadow mask 4, and the graphite film embedded in the aluminum film, the stud pins 5 ′, the contacts 6, and the funnel 3 applied to the panel 5. Passed through the anode cap (9).
이와 같이, 상기 콘택트(6)는 스크린에 주사된 전자빔이 전술한 바와 같이 애노드캡(9)으로 빠져나갈 수 있도록 하는 전기적 교량역할을 한다.As such, the contact 6 acts as an electrical bridge that allows the electron beam scanned on the screen to exit the anode cap 9 as described above.
그러나, 제2도의 (나)와 같이 콘택트(6)가 판스프링으로 구성되어 탄성력에 의하여 펀넬(3)에 도포된 흑연막에 접촉되어 있기 때문에 칼라브라운관의 외부 충격 진동 등에 의하여 콘택트가 순간적으로 단락되는 경우가 발생하였다.However, as shown in (b) of FIG. 2, since the contact 6 is constituted by a leaf spring and is in contact with the graphite film coated on the funnel 3 by elastic force, the contact is momentarily short-circuited due to external impact vibration of the color brown tube. Occurred.
따라서, 상기 와 같이 콘택트의 단락현상이 칼라브라운관의 작동중에 발생하게 되면 화면에 쇼크노이즈가 발생되는 문제점이 있었다.Therefore, when the short circuit of the contact occurs during the operation of the color CRT as described above, there was a problem that the shock noise occurs on the screen.
본 발명은 이러한 점을 감안하여 발명한 것으로서 새도우 마스크에 결합되어진 프레임에 결합된 커넥터와, 상기 커넥터의 선단을 펀넬내의 흑연막과 고정시키는 고정수단을 구비함으로써 브라운관에 충격이 가해진다 하더라도 커넥터가 단락되는 것을 방지하여 쇼크노이즈가 발생되지 않도록 하는데 문제점이 있다.The present invention has been invented in view of this point, and the connector has a connector coupled to a frame coupled to a shadow mask, and a fixing means for fixing the tip of the connector with the graphite film in the funnel, even if the CRT is impacted. There is a problem in preventing shock noise from occurring.
본 발명 칼라브라운관의 콘택트를 제3도 및 제4도에 의하여 설명하면 다음과 같다.Referring to the contact of the present invention color brown tube 3 and 4 as follows.
형광체가 도포된 새도우 마스크(101)와, 상기 새도우 마스크(101)가 결합된 프레임(102)과, 상기 프레임(102)과 판넬(103)을 접속하는 스터드핀(104)을 구성한 것에 있어서, 상기 새도우 마스크(101)에 결합되어진 프레임(102)에 핀결합될 수 있도록 일단에 핀홀(110)이 형성된 커넥터(105)와, 상기 커넥터(105)의 선단을 펀넬(106)내의 흑연막과 통전될 수 있도록 고정시키는 고정수단을 구비하였다.In the configuration of the shadow mask 101 coated with phosphor, the frame 102 to which the shadow mask 101 is coupled, and the stud pin 104 connecting the frame 102 and the panel 103, A connector 105 having a pinhole 110 formed at one end thereof so as to be pinned to the frame 102 coupled to the shadow mask 101, and the tip of the connector 105 is energized with the graphite film in the funnel 106. It was provided with a fixing means for fixing so that.
그리고, 상기 고정수단은 커넥터(105)에 형성된 결합홈(107)과, 상기 결합홈(107)이 삽입되는 삽입홈(108)이 형성된 커넥터핀(109)과, 상기 커넥터핀(109)을 펀넬(106)내에 형성시켜 흑연막과 연결되도록 구비하였다.The fixing means includes a connector pin 109 having a coupling groove 107 formed in the connector 105, an insertion groove 108 into which the coupling groove 107 is inserted, and a funnel of the connector pin 109. It was formed in (106), and was connected to the graphite film.
이와같이 구성된 칼라브라운관의 전자총에서 전자빔이 스크린에 주사되면 전자빔은 새도우 마스크(101)에 도포된 형광체를 발광시키고, 판넬(103)에 도포된 알루미늄막과 스터드핀(104)과 프레임(102)에 핀홀(110)이 형성된 일단이 핀 결합된 커넥터(105)의 선단이 연결된 커넥터핀(109)을 통하여 펀넬(106)에 내장된 흑연막을 거쳐 애노드캡으로 빠져나간다.When the electron beam is scanned on the screen by the electron gun of the color-brown tube configured as described above, the electron beam emits the phosphor coated on the shadow mask 101, and the pinhole is applied to the aluminum film, the stud pin 104 and the frame 102 applied to the panel 103. One end of the connector 110 having the 110 formed thereon exits to the anode cap via the graphite film embedded in the funnel 106 through the connector pin 109 connected to the tip of the connector 105.
이때 프레임(102)에 일단이 핀결합으로 고정된 커넥터(105)의 결합홈(107)을 펀넬(106)에 고정된 커넥터핀(109)의 삽입홈(108)에 삽입되어 고정되어 있기 때문에 브라운관에 충격이 가해져도 커넥터(105)가 커넥터핀(109)에서 순간적으로 단락되는 것을 방지할 수 있다.At this time, because the coupling groove 107 of the connector 105, one end of which is fixed to the frame 102 by pin coupling, is inserted into and fixed to the insertion groove 108 of the connector pin 109 fixed to the funnel 106. Even if an impact is applied to the connector 105, the connector 105 can be prevented from being short-circuited momentarily.
그리고, 상기 커넥터핀(109)은 펀넬(106)에 부착된 것이 아니고 펀넬(106) 제작시 유리의 돌출물로 형성한 표면에 전도성 물질을 도포함으로써 커넥터(105)의 고정은 물론이거니와 흑연막과 전지적 연결을 유지하여 순간적 단락을 방지하는 것이다.In addition, the connector pin 109 is not attached to the funnel 106, but the conductive material is applied to the surface formed by the projection of the glass when the funnel 106 is manufactured, as well as fixing the connector 105. Maintaining a connection prevents momentary short circuits.
이와 같은 본 발명은 프레임에 일단이 결합되어진 커넥터의 선단이 커넥터핀에 고정되는 것은 종래와 같이 판스프링의 탄성력으로 접촉 연결된 것이 아니고, 상호 결합연결이 되어 외부의 충격이나 진동에도 전기적 연결이 순간적으로 단락될 우려가 없다.In the present invention as described above, the front end of the connector coupled to the frame is fixed to the connector pin as opposed to the elastic force of the leaf spring as in the prior art, and the electrical connection is instantaneously connected to the external shock or vibration due to mutual coupling. There is no risk of short circuit.
따라서, 브라운관에 외부 충격이 가해진다 하더라도 브라운관의 화면에 발생하는 쇼크노이즈를 근본적으로 방지할 수 있는 발명이다.Therefore, the invention can fundamentally prevent shock noise occurring on the screen of the CRT even if an external impact is applied to the CRT.
