More specifically, the structure is diversified on the outer surface of a terminal pin coupled to an FBT connected to each component. It relates to a fixed structure of the terminal pin of the FBT that can prevent the power supply of the disconnection.

텔레비전의 수신장치에는 영상증폭회로, 음성회로, 전원부등으로 구성되며, 이와 같은 장치는 텔레비전 내부에 인쇄회로기판에 결합되어 회로적으로 배열되어 있는데, 인쇄회로기판은 텔레비전 수상기 케이스의 내부 바닥에 고정되고, 화면을 디스플레이하는 CRT에는 영상신호의 R.G.B.의 비임을 발사하는 전자총 등이 결합되어 있다.The receiver of the television consists of a video amplifier, audio circuit, power supply, etc., and such a device is coupled to a printed circuit board inside the television and is arranged in a circuit. The printed circuit board is fixed to the inner bottom of the television receiver case. The CRT displaying the screen is combined with an electron gun or the like that emits a RGB beam of an image signal.

전자총에 발사되는 전자빔에 의해 CRT의 화면에 디스플레이되도록 전자빔의 가속장치를 위한 고압의 전원을 공급시키는 FBT가 인쇄회로기판에 고정되어 CRT와 연결되어 있다.An FBT for supplying high voltage power for the accelerator of the electron beam to be displayed on the screen of the CRT by the electron beam emitted to the electron gun is fixed to the printed circuit board and connected to the CRT.

이와 같은 FBT가 고정된 종래의 텔레비전을 첨부된 도면을 참조하여 살펴보면 다음과 같다.Referring to the accompanying drawings, a conventional FBT fixed television is as follows.

도 1에는 종래의 텔레비전에 FBT가 결합되어 있는 단면도로서, 텔레비전(10) 내부에 CRT(18)가 결합되어 있고, 인쇄회로기판(12)에 고정된 FBT(20)가 CRT(18)의 후면에 연결되어 있다.1 is a cross-sectional view of a FBT coupled to a conventional television, in which the CRT 18 is coupled to the inside of the television 10, and the FBT 20 fixed to the printed circuit board 12 is the rear surface of the CRT 18.

이상에서 설명한 본 고안의 작동상태 및 작용효과를 살펴보면 다음과 같다.Looking at the operation state and the effect of the present invention described above are as follows.

도 3과 같이 텔레비전(10) 내부의 인쇄회로기판(12)에 결합된 FBT(20)는 전원이 공급되면 내부의 장치에 의해 발생되는 고압의 전류가 리드선(24)를 통해 CRT(18) 등에 공급시킨다. 이때, 전자총에 의해 주사된 전자빔의 플라이 백(Fly Back) 현상이 가속화되고, 인쇄회로기판(12)에 납땜(35)에 의해 결합된 단자핀(32)은 인쇄회로기판(12)에 부설된 부품과 연결되어 고압의 전원을 공급시키게 된다. 또한, 단자핀(32)에 형성된 노치부(34)에 납땜(35)의 결합력이 증가하게 된다.As shown in FIG. 3, in the FBT 20 coupled to the printed circuit board 12 inside the television 10, when a power is supplied, a high-voltage current generated by an internal device is supplied to the CRT 18 through the lead wire 24. Supply it. At this time, the fly back phenomenon of the electron beam scanned by the electron gun is accelerated, and the terminal pin 32 coupled by the solder 35 to the printed circuit board 12 is attached to the printed circuit board 12. It is connected to the component to supply high voltage power. In addition, the coupling force of the solder 35 is increased to the notch 34 formed in the terminal pin 32.

따라서, FBT(20)의 단자핀(32)의 노치부(34)에 인쇄회로기판(12)과의 납땜에 의한 결합력이 증가되어 텔레비전(10)의 외부 충격이나 이동시에 분리되지 않으므로써, FBT(20)의 고압의 전류가 차단되는 것을 방지할 수 있다.Therefore, the bonding force of the FBT 20 by the soldering with the printed circuit board 12 is increased on the notch 34 of the terminal pin 32 of the FBT 20, so that the FBT 20 is not separated during external impact or movement of the TV 10. It is possible to prevent the high voltage current of 20 from being cut off.
