본 고안은 플라이백트랜스포머의 저압코일보빈에 관한 것으로, 특히 저압코일보빈 하단에 형성된 단자부측면에다 절개홈을 형성시켜 놓음으로서 저압코일이 접속되는 핀이 용이하게 삽입되도록 한 플라이백트랜스포머의 저압코일보빈에 관한 것이다.The present invention relates to a low pressure coil bobbin of a flyback transformer, and in particular, by forming an incision groove in a side of a terminal portion formed at the bottom of the low pressure coil bobbin, a low pressure coil bobbin of a flyback transformer for easy insertion of a pin to which the low pressure coil is connected. It is about.
일반적으로 플라이백트랜스포머는 저압코일보빈 하단에 다수의 단자부를 형성시키고, 상기 단자부에는 저압코일이 접속되는 핀이 삽입되어지도록한 구조로 되어 있는데, 이와 같이 상기 핀이 삽입되는 단자부에 있어서 종래에는 중앙에 원통형홈을 형성시켜 핀이 삽입되도록 하고 있었으나, 이렇게 핀을 홈에 삽입시키다보면 홈내에 존재하는 공기의 압력에 의해 삽입되는 핀이 밀려나오는 현상이 발생하게 되는바, 이때문에 이를 보완하기위해 상기 원통형홈 하단에 외부와 통하는 구멍을 형성시켰으나, 보빈을 사출성형시킬때 또는 기타의 이유로 하여 구멍이 막히거나 핀직경자체의 오차가 있을때 상기 핀을 홈에 삽입시키기가 어려웠고 또한 사출물 자체의 오차로 말미암아 삽입되는 핀보다 지름이 큰 원통형홈을 형성시켰을때 상기 핀을 고정시킬수가 없게 되는 문제점이 발생하였다.In general, the flyback transformer has a structure in which a plurality of terminal portions are formed at the lower end of the low pressure coil bobbin, and the pins to which the low pressure coils are connected are inserted in the terminal portions. The pin was inserted into the groove by forming a cylindrical groove, but when the pin is inserted into the groove, the pin is pushed out by the air pressure present in the groove. A hole communicating with the outside was formed at the bottom of the cylindrical groove, but it was difficult to insert the pin into the groove when the bobbin was blocked by injection molding or for other reasons, and the pin diameter itself had an error. When the pin is fixed when a cylindrical groove having a larger diameter than the pin to be inserted is formed. This was not a problem that can occur.
이에 본 고안은 상기 문제점을 해결하기 위하여 원통형홈이 형성된 단자부 측면의 일부를 절개한 절개홈을 형성시켜 핀을 삽입하도록 된 플라이백트랜스포머의 저압코일보빈을 제공하는데 그 목적이 있다.In this regard, an object of the present invention is to provide a low-pressure coil bobbin of a flyback transformer in which a pin is inserted to form a cutout groove in which a portion of a side surface of a terminal portion having a cylindrical groove is formed to solve the above problems.
이하, 본 고안의 구성 및 작용, 효과를 예시된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the illustrated drawings.
본 고안은 플라이백트랜스포머의 저압코일보빈(1) 하단에 형성되어 핀(2)을 고정하도록 된 단자부(3)에 있어서, 상기 단자부(3) 중앙에는 원통형홈(4)과 구멍 (5)을 형성시키고, 측면에는 일부를 절개하여 절개홈(6)을 형성시킨 구조로 되어 있다.The present invention has a terminal portion (3) formed at the bottom of the low-pressure coil bobbin (1) of the flyback transformer to fix the pin (2), the center of the terminal portion (3) in the cylindrical groove (4) and the hole (5) It forms and cuts a part in the side surface, and has the structure which formed the incision groove 6.
상기와 같이 본 고안은 핀의 직경과 단자부 중앙에 형성된 원통형홈의 직경이 잘못 제작되더라도 상기 핀이 단자부에 용이하게 고정되도록 한 것으로서, 제1도는 본 고안의 저면도를 나타낸 것인바, 즉 저압코일보빈(1)하단에 형성되어 저압코일이 접속되는 핀(2)을 고정하도록 된 다수의 단자부(3)를 도시하고 있는 것이고, 제2도는 본 고안에 따른 요부확대 단면도를 나타낸 것으로, 즉 단자부(3) 중앙에는 원통형홈(4)과 구멍(5)을 형성하고, 측면에는 일부를 절개한 절개홈(6)을 형성하여 상기 원통형홈(4) 직경보다 큰 핀(2)이 삽입될때 프라스틱으로 사출성형된 상기 단자부(3)의 절개홈(6)이 벌어지면서 삽입되도록 하며 이때 상기 원통형홈(4)하단에 형성된 구멍(5)이 사출성형하는 과정에서 또는 기타 이유로 해서 막힐경우 원통형홈(4) 내부에 존재하는 공기는 상기절개홈(6) 틈으로 배출되는 것을 도시하고 있는 것이다.As described above, the present invention is to ensure that the pin is easily fixed to the terminal portion even if the diameter of the pin and the diameter of the cylindrical groove formed in the center of the terminal portion is made incorrectly, Figure 1 shows the bottom view of the present invention, that is, low pressure coil A plurality of terminal portions 3 formed at the bottom of the bobbin 1 and configured to fix the pins 2 to which the low pressure coils are connected are shown, and FIG. 2 is an enlarged cross-sectional view of the main portion according to the present invention. 3) A cylindrical groove 4 and a hole 5 are formed in the center, and a cutout groove 6 is formed at the side thereof to form a plastic when the pin 2 larger than the diameter of the cylindrical groove 4 is inserted. The injection groove 6 of the injection molded terminal portion 3 is inserted while being opened. At this time, when the hole 5 formed at the lower end of the cylindrical groove 4 is blocked in the process of injection molding or for other reasons, the cylindrical groove 4 Ball inside) The machine is shown to be discharged into the gap in the cutting groove (6).
또한 상기 제2도에서는 원통형홈(4)의 직경이 핀(2)의 직경보다 크게 형성되어 있을때 상기 핀(2)이 원통형홈(4)에 여분의 공간을 남기면서 삽입되더라도 코일보빈이 플라이백트랜스포머의 몸체에 결합될때 에폭시액으로 충전시키기 때문에 상기 에폭시액이 상기 절개홈(6)이나 원통형홈(4) 내부에는 충전이되 상기 핀(2)을 더욱더 확고히 고정시켜준다.In addition, in FIG. 2, when the diameter of the cylindrical groove 4 is larger than the diameter of the pin 2, even if the pin 2 is inserted while leaving extra space in the cylindrical groove 4, the coil bobbin is flyback Since the epoxy liquid is filled in the incision groove 6 or the cylindrical groove 4 when it is coupled to the transformer body, the pin 2 is more firmly fixed.
제3도는 종래의 저압코일보빈 요부확대사시도를 나타낸 것으로, 단자부(3)의 중앙에 원통형홈(4)을 형성하고, 상기 원통형홈(4) 하단에는 외부와 통하는 구멍 (5)이 형성되어 있어서 핀(2)이 삽입될때 상기 원통형홈(4) 내부에 존재하는 공기는 구멍(5)을 통하여 배출된다하더라도 상기 원통형홈(4)의 직경보다 큰 핀(2)은 삽입시킬 수 없는 문제점을 가지고 있다.Figure 3 shows a conventional low-pressure coil bobbin enlarged perspective view, the cylindrical groove 4 is formed in the center of the terminal portion 3, the lower end of the cylindrical groove 4 is formed with a hole 5 for communicating with the outside When the pin 2 is inserted, even if air existing in the cylindrical groove 4 is discharged through the hole 5, the pin 2 larger than the diameter of the cylindrical groove 4 cannot be inserted. have.
이와 같이 본 고안은 단자부(3)중앙에 형성된 원통형홈(4) 직경보다 큰 핀(2)이나 또는 핀(2)의 직경보다 큰원통형홈(4)을 형성시키더라도 상관없이 용이하게 핀(2)이 삽입될뿐아니라 구멍(5)이 막히더라도 공기가 절개홈(6)을 통해 배출되는 효과가 있다.In this way, the present invention can easily form the pins 2 larger than the diameter of the cylindrical grooves 4 formed in the center of the terminal portion 3 or the cylindrical grooves 4 larger than the diameter of the pins 2. In addition to being inserted, there is an effect that the air is discharged through the incision groove (6) even if the hole (5) is blocked.
