본 고안은 포커스유니트 일체형 플라이백 트랜스포머에 관한 것으로 특히 포커스유니트가 결합되는 보빈케이스의 결합부에 실시되는 포커스유니트 접착제 누출방지구조에 관한 것이다.The present invention relates to a focus unit integrated flyback transformer, and more particularly, to a focus unit adhesive leakage preventing structure which is implemented at a coupling portion of a bobbin case to which a focus unit is coupled.

종래의 포커스유니트 일체형 플라이백 트랜스포머에서는 보빈케이스 내측에 저압코일보빈과 고압코일보빈을 삽입한후 에폭시절연수지를 주입경화시키므로서 별도로 제작되어 보빈케이스의 일측면에 착설시키는 포커스유니트 결합부를 접착제로 도포하여 절연수지물의 누출을 방지코져 하였다.In the conventional focus unit integrated flyback transformer, a low pressure coil bobbin and a high pressure coil bobbin are inserted into the bobbin case, and then the focus unit coupling part which is manufactured separately by injecting and curing epoxy insulating resin and installed on one side of the bobbin case is coated with an adhesive. To prevent leakage of insulating resin.

이러한 접착제의 도포작업시에 접착제의 량이 적으면 충분히 도포되지 않아 밀폐성이 없으므로 이를 우려하여 다소 충분하게 도포량을 늘리는 바, 이 경우에 제1도 및 제2도에 도시한 바와 같이 보빈케이스(1)의 결합단(2)과 포커스유니트(3)의 결합단(4)사이의 폭이 좁은홈(5)으로 형성되어 있어서 빈번하게 보빈케이스(1)의 결합단(2)외측이나 포커스유니트(3)의 표면으로 접착액이 흘러넘치게 되고 이에 따라 합성수지를 용해하면서 경화되는 접착액의 성질에 의해 누출된 부분은 표면이 파여지면서 자국이 남는등 외관이 오손되는 폐단이 있었던 것이다.When the amount of the adhesive is small when the adhesive is applied, the coating is not sufficiently applied and there is no sealing property. Therefore, the amount of the adhesive is sufficiently increased, and in this case, as shown in FIGS. 1 and 2, the bobbin case 1 Is formed of a narrow groove 5 between the coupling end 2 of the focusing unit 3 and the coupling end 4 of the focus unit 3 so that the coupling end 2 of the bobbin case 1 is frequently outside the focusing unit 3 or the focus unit 3. The leaked part due to the property of the adhesive liquid that hardens while dissolving the synthetic resin due to the overflow of the adhesive liquid to the surface of) has left the end of the surface being damaged, such as markings left behind.

본고안은 종래의 이러한 단점을 보완코져 안출된 것으로서 이하 첨부된 도면과 함께 상세히 설명하면 다음과 같다.The present invention has been made to compensate for these disadvantages of the prior art as described in detail with the accompanying drawings as follows.

공지의 포커스유니트일체형 플라이백 트랜스포머의 구성으로 포커스유니트 결합부가 보빈케이스(1)의 일측면에 포커스유니트(3)의 결합단(4)이 착설되게 내단으로 경사진 결합단(2)이 형성된 것에 있어서 보빈케이스(1)의 결합단(2)외측 둘레에 양끝단에는 단턱(6)(6')이 형성된 다소깊이 방지호(5')을 형성시켜서 된 구성이다.In the configuration of a known focus unit integrated flyback transformer, the focus unit coupling part is formed with a coupling end 2 inclined to the inner end such that the coupling end 4 of the focus unit 3 is installed on one side of the bobbin case 1. In this configuration, a slightly deeper prevention arc 5 'is formed at both ends of the bobbin case 1 at the outer circumference of the coupling end 2 to form stepped portions 6 and 6'.

이와같은 구성의 본고안은 다소깊이 방지홈(5')이 보빈케이스(1)의 결합단(2) 외측둘레에 형성되어 있어서 포커스유니트(3)를 보빈케이스(1)의 결합단(2) 내단에 착설시킨후 포커스 유니트결합단(4) 사이의 좁은홈(5)에 접착제를 도포할때 일부 접착액이 보빈케이스의 결합단(2)을 넘어 흘러 넘쳐도 방지홈(5')내에서 단턱(6)(6')으로 유출이 방지되면서 고이게 되므로 보빈케이스(1)의 외표면으로의 누출이 완전차단되어, 접착액에 의한 외표면의 오손을 방지하고 깨끗한 외관을 갖는 플라이백 트랜스포머를 제공할수 있는 것이다.In this configuration of this configuration, the prevention groove 5 'is formed at the outer periphery of the coupling end 2 of the bobbin case 1 so that the focus unit 3 is coupled to the coupling end 2 of the bobbin case 1. When the adhesive is applied to the narrow grooves 5 between the focus unit coupling stages 4 after installation at the inner end, even if some adhesive liquid overflows beyond the coupling ends 2 of the bobbin case, the stepped in the prevention grooves 5 '. (6) (6 ') prevents leakage and prevents leakage to the outer surface of the bobbin case (1), thereby preventing fouling of the outer surface by the adhesive liquid and providing a flyback transformer having a clean appearance. You can do it.
