도 3은 본 고안에 따른 텔레비전에 FBT가 결합된 상태의 단면도가 도시되어 있는데, 텔레비전 내부에 부설된 인쇄회로기판(12)에 도면에 도시하지 않은 CRT에 결합되는 리드선(24)이 인출된 FBT(20)가 설치된다.3 is a cross-sectional view showing a state in which the FBT is coupled to the television according to the present invention, the FBT with the lead wire 24 coupled to the CRT not shown in the drawing on the printed circuit board 12 installed inside the television. 20 is installed.
인쇄회로기판(12)은 면상에 쌍으로 된 체결구멍(14)이 형성되고, 상기 체결구멍(14)과 체결구멍(14) 사이에는 일정간격으로 다수개의 고정구멍(16)이 형성된다.The printed circuit board 12 has a pair of fastening holes 14 formed on a surface thereof, and a plurality of fixing holes 16 are formed at predetermined intervals between the fastening holes 14 and the fastening holes 14.
FBT(20)는 도면에 도시되지 않은 권선된 코일등이 결합된 케이스(22) 내부에 부설되고, 케이스(22)의 외부에는 전선이 연결된 포커스팩과 페라이트 코어등이 설치된다. 그리고 케이스(22)의 상측면에는 리드선(24)이 결합되어 도면에 도시되지 않은 CRT 등에 연결된다. 상기 케이스(22) 아랫쪽 테두리에는 걸림턱이 형성된 스냅피트(30)가 마련되고, 저면에는 케이스(22)의 내부품과 전기적으로 접속되는 다수개의 단자핀(32)이 설치된다. 단자핀(32)의 외표면에는 도 4에 도시된 바와 같이 길이방향으로 다수개의 V자형 노치부(34)가 형성된다.The FBT 20 is installed inside the case 22 to which the wound coil and the like, which are not shown, are coupled, and the focus pack and the ferrite core, etc., to which the electric wires are connected, are installed outside the case 22. And the lead wire 24 is coupled to the upper side of the case 22 is connected to the CRT and the like not shown in the figure. The lower edge of the case 22 is provided with a snap pit 30 having a locking jaw, and a plurality of terminal pins 32 electrically connected to the internal parts of the case 22 are provided at the bottom. On the outer surface of the terminal pin 32, a plurality of V-shaped notches 34 are formed in the longitudinal direction as shown in FIG.

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.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.
또한, 단자핀(32)에서 형성된 노치부(34)에 납땜(35)의 결합력이 증가하게 된다.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.
