3 : 포커스유니트 4, 4' : 반구의 홈3: focus unit 4, 4 ': hemisphere groove

5 : 사각형요홈 FW : 리드선5: square groove FW: lead wire

본고안은 전자제품의 음극선관에 고압을 공급해주는 플라이백 트랜스포머에 있어서 케이스와 포커스유니트(focus unit)상부의 포커스리드선 인출부의 결합부위로 절연수지물인 에폭시(Epoxy)누출방지 구조에 관한 것이다.This paper relates to the epoxy leakage prevention structure, which is an insulating resin, at the coupling portion of the focus lead wire lead-out portion of the case and the focus unit in the flyback transformer for supplying high pressure to the cathode ray tube of the electronic product.

일반적으로 플라이백 트랜스포머케이스(1)의 결합틀(2)에 결합된 포커스유니트(3)의 결합부위(4)에는 케이스내에 주입되는 절연수지물의 누설을 방지하기 위하여 신나와 같은 접착제를 도포하게 되는데 제 1 도에 도시한 같이 포커스유니트(2)상부의 포커스리드선(FW)인출부위의 협지력이 미약하여 포커스리드선(FW)의 유동으로 인하여 약간의 오차만 발생하더라도 포커스인출부위(4)로 절연체인 에폭시가 누출되어 절연불량을 초래하였다.In general, an adhesive such as a thinner is applied to the coupling portion 4 of the focus unit 3 coupled to the coupling frame 2 of the flyback transformer case 1 to prevent leakage of the insulating resin injected into the case. As shown in FIG. 1, even if only a slight error occurs due to the flow of the focus lead line FW because the clamping force of the focus lead line FW lead-out portion above the focus unit 2 is weak, an insulator is applied to the focus lead-out portion 4. Phosphorous epoxy leaked, resulting in poor insulation.

따라서 본 고안은 이러한 종래의 제반단점과 결점을 해소하기 위하여 케이스의 포커스유니트 결합틀 상부에 반구홈을 형성한 사각형요홈을 형성시켜 포커스리드선의 유동을 방지하고 절연수지물 에폭시의 누설을 방지케 하려는데 그목적이 있다.Therefore, the present invention is intended to prevent the flow of the focus lead wire and to prevent the leakage of the insulating resin epoxy by forming a rectangular groove formed with a hemisphere groove on the focus unit coupling frame of the case in order to solve the above-mentioned general disadvantages and shortcomings. The purpose is.

상기의 목적을 달성시킬수 있는 본고안의 구성을 첨부된 도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the configuration of the present invention that can achieve the above object in more detail based on the accompanying drawings as follows.

도시한 바와같이 케이스(1)의 결합틀(2)에 포커스유니트(3)가 누름결합되는 통상의 것에 있어서, 상기의 케이스(1)결합틀(2)의 상부에 반구의 홈(4)(4')을 형성한 사각형요홈(5)을 결합틀(2)과 일체화로 사출성형시켜서 구성된 것이다.As shown in the drawing, the focus unit 3 is press-fitted to the coupling frame 2 of the case 1, and the hemispherical grooves 4 ( 4 ') is formed by injection molding the square groove (5) formed integrally with the coupling frame (2).

이와같이 구성된 본고안에 있어서 포커스리드선(FW)이 인출부위를 제 4 도에 도시한 바와같이 반구의홈(4)(4')의 부위에서 삽지하고 있으므로 포커스리드선의 유동이 전혀 없게되며 내부에 절연수지물인 에폭시의 주입시 소량의 누출이 있더라도 사각형요홈(5)부에 에폭시가 고이기 때문에 외부로 누출되는 것을 막고 반구의홈(4)(4')에 결합된 포커스리드선(FW)을 사각형요홈(5)에 고인 에폭시로 접착되고 에폭시는 외부로 누출이 불가능하게 된다.In this paper, the focus lead wire FW inserts the lead portion into the hemispherical grooves 4 and 4 'as shown in FIG. 4. Therefore, there is no flow of the focus lead wire and there is no insulation resin inside. Even if there is a small amount of leakage when the epoxy is injected into the water, the epoxy is accumulated in the rectangular groove 5 to prevent leakage to the outside, and the focus lead wire FW coupled to the hemisphere grooves 4 and 4 'is removed. It is adhered to the epoxy accumulated in 5) and the epoxy is impossible to leak to the outside.

이상 설명한 바와같이 본고안에 의하면 케이스와 포커스유니트의 결합후 포커스리드선인출부로 절연수지물인 에폭시가 누출되는 것을 크게 염려할 필요가 없게되므로 작업편리성을 기할수 있는 한편 원가절감과 종래의 에폭시 누출에 따른 불량율을 감소시킬수 있는 효과가 있다.As described above, according to this proposal, there is no need to worry about the leakage of the epoxy resin, which is an insulating resin, into the focus lead wire lead-out unit after the case and the focus unit are combined. There is an effect that can reduce the defective rate.
