본 고안은 텔레비젼 및 모니터 등의 브라운관에 고압을 공급하는 플라이백 트랜스포머에 관한 것으로서, 특히 저압보빈의 1차전압과 3차전압을 절연하기 위한 플라이백 트랜스포머의 저압보빈에 관한 것이다.The present invention relates to a flyback transformer for supplying high pressure to a CRT, such as a television and a monitor, and more particularly to a low voltage bobbin of a flyback transformer for insulating the primary voltage and the third voltage of the low voltage bobbin.

종래에는 제1도의(a)에 도시한 바와 같이 플라이백 트랜스포머용 저압보빈(1)의 보빈등체(2) 외주연에 코일분리편(11)을 수개 환설하여 권선부(7)를 형성하고 하대의 외주연에는 단자돌기(4)를 수개 돌출성형하여 단자핀(5)을 고정하였다. 이와 같이 구성된 저압보빈(1)의 동체(2)의 외주연에 수개 환설된 코일분리편(11) 사이에 1차코일(6)과 3차코일(6')을 권선하여 하대의 외주연에 일체로 돌출성형된 단자돌기(4)의 단자핀(5)에 연결납땜하여 제작되는데 보빈등체(2)의 외주연에 1차코일 및 3차코일(6)(6')이 권선부(7)상에 같이 권선되어 있으므로 3차코일(6')의 많은 로드(Load)가 1차코일(6)에 영향을 주어 화면의 일그러짐 현상및 간섭현상을 주무로서 절연상에 여러가지 문제점이 있어 신뢰성을 저하시키는 요인이 되었다.Conventionally, as shown in (a) of FIG. 1, a plurality of coil separation pieces 11 are provided on the outer periphery of the bobbin body 2 of the low-pressure bobbin 1 for the flyback transformer to form the winding part 7. On the outer periphery of the lower part, the terminal pins 4 were fixed by protruding several terminal protrusions 4. The primary coil 6 and the tertiary coil 6 'are wound between the coil separating pieces 11 rounded around the outer periphery of the body 2 of the low pressure bobbin 1 configured as described above, It is manufactured by connecting and soldering to the terminal pins 5 of the terminal protrusions 4 protruding integrally, and the primary coil and the tertiary coils 6 and 6 'are wound around the outer periphery of the bobbin body 2. 7) Since many windings of the tertiary coil (6 ') affect the primary coil (6) because they are wound together, there are various problems on the insulation due to the distortion and interference of the screen. It became the factor which lowered.

그래서 상기와 같은 문제점을 해결하기 위하여 제1도의(b)(c)에 도시한 바와같이 저압보빈(1)의 보빈등체(2)에 1차코일(6)과 3차코일(6')을 절연필름(8)으로 분리하여 권선하는 것과, 저압보빈(1)을 보빈등체(2)와 원호형상의 보빈등체(3)을 별도로 제작하여 하측에 협지돌기(9)가 형성된 저압보빈(1)의 보빈등체(2)에 1차코일(6)을 권선하고 이 보빈등체(2)의 외측으론 상기협지돌기(9)가 결합될수 있게 하측에 협지부(10)가 형성된 원호형상의 보빈등체(3)의 외주연에 3차코일(6')을 권선하여 결합한후이 1차, 3차코일(6)(6')을 보빈등체(2) 하대에 들출성형된 단자돌기(4)의 단자핀(5)에 연결하여 납땜하였다.Thus, in order to solve the above problems, as shown in (b) and (c) of FIG. 1, the primary coil 6 and the tertiary coil 6 'are placed on the bobbin body 2 of the low pressure bobbin 1. The low pressure bobbin with the squeezing protrusion 9 formed on the lower side of the bobbin body 2 and the arcuate bobbin body 3 separately manufactured from the low pressure bobbin 1 The primary coil 6 is wound around the bobbin body 2 of (1), and the clamping part 10 is formed in the lower part so that the said clamping protrusion 9 may be coupled to the outer side of this bobbin body 2. After winding and coupling the tertiary coil 6 'to the outer circumference of the shaped bobbin body 3, the primary and tertiary coils 6, 6' are extruded under the bobbin body 2 under the terminal. It was connected to the terminal pin 5 of the protrusion 4 and soldered.

이와같이 전자의 경우에는 보빈등체(2)의 하대에 수개형성된 단자돌기(4)의 단자핀(5)에 1차코일(6)가 3차코일(6')의 연결시 들뜸이 발생하므로 단선의 우려가 있고, 후자의 경우에는 보빈등체(2)의 권선부(7)에 1차코일을 권선한후 원호상의 보빈등체(8)을 결합하여 3차코일(6')을 권선부(7)에 권선하여 보빈등체(2)의 하대에 형성된 단자핀(5)에 납땜연결하여야 하므로 작업시간이 많이 소요되고 또한 보빈등체(2) 하부에 돌출성형된 단자돌기(4)의 단지핀(5)에 연결납땜시, 원호상의 보빈등체(3)에 권선된 3차코일(6')을 보빈등체(2)의 하대에 들뜸의 발생하여 단선의 우려가있어 작업공수가 증대되는 한편 생산성을 저하시키는 문제점이 있다.As described above, in the former case, since the primary coil 6 is lifted up when the tertiary coil 6 'is connected to the terminal pin 5 of the terminal protrusion 4 formed under the bobbin body 2, disconnection occurs. In the latter case, the primary coil is wound around the winding portion 7 of the bobbin body 2, and then the tertiary coil 6 'is wound by combining the bobbin body 8 on the arc. (7) and the soldering to the terminal pin (5) formed on the lower base of the bobbin body (2) takes a lot of work time and also of the terminal projection (4) protruding in the bobbin body (2) When soldering to the pin 5, the third coil 6 'wound around the circular bobbin body 3 is lifted to the lower side of the bobbin body 2, and there is a risk of disconnection. While increasing, there is a problem of lowering productivity.

따라서 본 고안은 상기의 문제점을 해결하기 위하여 안출된 것으로서 저압보빈을 보빈등체와 원호상의 보빈등체를 분리하여 각각의 등체하부에 단자핀이 고정된 단자돌기를 돌출성형하여 결합하므로서 완전한 절여늘할수 있는 것은 물론 각각의 동체에 형성된 단자돌기의 단자핀에 코일을 납땜연결하므로서 들뜸현상으로 인한 단선의 우려를 완전배제 할수 있도록한 것이 특징이다. 이하 본 도안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the above problems, and the low-pressure bobbin is separated by the bobbin body and the arc-shaped bobbin body, and the terminal projections are fixed to the lower part of each body by projecting and forming the terminal projections. Of course, it is possible to completely eliminate the fear of disconnection due to the lifting phenomenon by soldering the coil to the terminal pin of the terminal projection formed on each fuselage. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도 및 제4도에 도시한 바와같이 저압보빈(1)이 보빈 등체(2)의 상부에는 권선부(7)을 마련하고 하부일측부에는 단자핀(5)이 고정된 단자돌기(4)를 형성하여, 단자돌기(4)바로위에 협지돌기(9)를 돌출성형하여 이 보빈등체(2)에 삽입설치되는 원호상의 보빈등체(3)상부에 권선부(7)을 마련하고 하부타측부에 단자핀(5)이 고정된 단자돌기(4)를 형설하며 하측으론 상기 협지돌기(9)와 대응하게 협지부(10)를 형성하여 상호체결 고정되도록 구성된 것이다. 이와같이 구성된 본 고안은 보빈등체(2)의 상부권선부(7)에 1차코일(6)을 권선하여 하대일측부에 형설된 단자돌기(4)의 단자핀(5)에 납땜 연결하고 원호상의 보빈등체(3)의 상부권부(7)에는 3차코일(6')을 권선하여 하부 하측부에 형성된 단자돌기(4')의 단자핀(5')에 연결하여 보빈등체(2)의 외주연으로 원호상의 보빈등체(3)를 끼워, 각각의 등체에 형설된 협지돌기(9)을 협지부(10)에 결합하는 것이다.As shown in FIGS. 3 and 4, the low pressure bobbin 1 provides a winding portion 7 on the upper part of the bobbin body 2 and a terminal protrusion 4 on which the terminal pin 5 is fixed on the lower side. ), And a winding portion 7 is provided on the circular bobbin body 3, which is inserted into the bobbin body 2, by protruding the clamping protrusion 9 directly above the terminal protrusion 4, A terminal protrusion 4 having a terminal pin 5 fixed to the other lower side is formed, and a lower portion 10 is formed to correspond to the clamping protrusion 9 to be fastened to each other. The present invention constructed as described above has a primary coil 6 wound on the upper winding portion 7 of the bobbin body 2 and soldered to the terminal pins 5 of the terminal protrusions 4 formed on one side of the lower base, and arced. The upper winding portion 7 of the upper bobbin body 3 of the upper winding 3rd coil 6 'is connected to the terminal pin 5' of the terminal projection 4 'formed at the lower lower portion and the bobbin body 2 The outer circumferential edge of) is inserted into the circular arc-shaped bobbin body 3, and the clamping protrusions 9 formed on the respective bodies are coupled to the clamping unit 10.

이상과 같은 본 고안은 1차코일과 3차코일을 각각의 보빈등체에 형설된 단자돌기의 단자핀에 납땜을 연결하여 결합하므로서 종래의 들뜸을 완전배제한 것이며 각각의 보빈등체를 각각 분리권선하여 각각의 등체에 직접납땜 연결한후 결합하므로서 작업공정이 용이함은 물론 생산성이 향상되는 것이며 아울러 들뜸으로 인한 단선의 우려가 없어 신뢰성을 향상시키는 것이다.The present invention as described above, by combining the primary coil and the tertiary coil by connecting the solder to the terminal pin of the terminal projection formed on each bobbin body, the conventional lifting is completely eliminated, and each bobbin body is wound separately By soldering directly to each isolator and then joining, the work process is easy and productivity is improved, and there is no fear of disconnection due to lifting, thereby improving reliability.
