본 고안은 FBT(Fly Back Transformer)용 저압부빈 단자핀에 관한 것으로, 상세하게 설명하면 저압보빈의 단자핀 중간부위에 너얼링(Kunuling)을 형성함으로써, 이에 권선되는 코일의 플림 및 단선을 방지하기 위한 저압보빈 단자핀에 관한 것이다.The present invention relates to a low-pressure bobbin terminal pin for FBT (Fly Back Transformer), to be described in detail to form a nuling (Kunuling) in the middle of the terminal pin of the low-voltage bobbin, to prevent the coil and winding of the coil wound around It relates to a low voltage bobbin terminal pin.
종래의 FBT용 저압보빈은 제3도에 도시한 바와 같이, 저압보빈(10)의 보빈단자(11)에 핀 삽입구멍(12)을 천설하고, 상기 핀 삽입구멍(12)내에 단자핀(13)을 삽입하여 코일(14)을 권선시킨 구성으로 이루어진다.In the conventional low pressure bobbin for FBT, as shown in FIG. 3, the pin insertion hole 12 is laid in the bobbin terminal 11 of the low pressure bobbin 10, and the terminal pin 13 is inserted into the pin insertion hole 12. ) Is made of a configuration in which the coil 14 is wound.
상기와 같은 구조를 갖는 종래의 FBT용 저압보빈은, 저압보빈단자(11)의 핀 삽입구멍(12)내에 단자핀(13)을 단순히 꽂아 놓은 상태로 결합되기 때문에 상기 핀 삽입구멍내에서 단자핀(13)이 쉽게 빠져버리게 됨은 물론, 상기 단자핀의 돌출부에 코일(14)을 권선시 표면이 매끄러운 관계로 인하여 이에 권선되는 코일(14)이 쉽게 풀려지게 되고, 이에따라 단선이 자주 발생하게 되어 제품의 신뢰도를 저하시키게 되는 문제점이 있었다.In the conventional low pressure bobbin for FBT having the above structure, the terminal pin 13 is simply inserted into the pin insertion hole 12 of the low pressure bobbin terminal 11 so that the terminal pin is inserted in the pin insertion hole. (13) is easily pulled out, of course, due to the smooth surface of the coil 14 when winding the coil 14 to the protrusion of the terminal pin, the coil 14 is easily released, thereby causing disconnection frequently There was a problem that reduces the reliability of.
본 고안은 상술한 바와 같이 종래의 문제점을 개선하기 위하여 안출된 것으로 그 목적은 저압보빈 단자의 단자핀 중간부위에 너얼링을 형성함으로써, 이부위에 권선되는 코일이 쉽게 풀려지지 않고, 이에 따라 코일의 단선을 방지함은 물론, 단자핀이 핀 삽입구멍내에서 쉽게 빠지지 않으므로서 제품의 신뢰도를 크게 향상시킨 FBT용 저압보빈 단자핀을 제공하는데 있다.The present invention was devised to improve the conventional problems as described above, and its purpose is to form a knurling at the middle of the terminal pin of the low-voltage bobbin terminal, so that the coil wound on this part is not easily released, and thus The present invention provides a low pressure bobbin terminal pin for an FBT that prevents disconnection, and greatly improves the reliability of the product because the terminal pin is not easily removed from the pin insertion hole.
상기 목적을 달성하기 위한 기술적인 구성으로서 본 고안의 저압보빈 단자핀의 구성은, 저압보빈의 핀 삽입구멍내에 삽입되는 단자핀의 중간부위에 너얼링부를 형성토록하고, 상기 너얼링부에 코일을 권선시키는 것이 특징이다.As a technical configuration for achieving the above object, the configuration of the low pressure bobbin terminal pin of the present invention is to form a knurling portion in the middle portion of the terminal pin inserted into the pin insertion hole of the low pressure bobbin, and wound the coil on the knurling portion. It is characteristic to let.
이하, 첨부된 도면에 의거하여 본 고안을 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 의한 저압보빈 단자내에 단자핀이 결합된 상태를 도시한 요부 확대 단면도이고, 제2도는 저압보빈 단자핀의 중간부위에 너얼링을 형성한 상태를 도시한 단자핀의 확대 사시도로서, 저압보빈(6)의 보빈 단자(1)내에 핀 삽입구멍(2)을 천설하고, 상기 핀 삽입구멍(2)내에 단자핀(3)을 삽입한 저압보빈에 있어서, 상기 핀 삽입구멍(2)내에 삽착되는 단자핀(3)의 중간부위에 너얼링부(5)를 형성하고, 상기 너얼링부에 코일(4)을 권선시킨 구조로 이루어진다.1 is an enlarged cross-sectional view of a main portion showing a state in which the terminal pin is coupled in the low-pressure bobbin terminal according to the present invention, Figure 2 is an enlarged perspective view of the terminal pin showing a state in which the knurling is formed in the middle portion of the low-pressure bobbin terminal pin In the low pressure bobbin in which the pin insertion hole 2 is installed in the bobbin terminal 1 of the low pressure bobbin 6 and the terminal pin 3 is inserted into the pin insertion hole 2, the pin insertion hole ( 2) the knurling part 5 is formed in the intermediate part of the terminal pin 3 inserted in the inside, and the coil 4 is wound around the knurling part.
따라서, 저압보빈(6)의 단자핀(3) 중간부위에 너얼링부(5)를 형성한 후 제1도에 도시한 바와 같이, 핀 삽입구멍(2)내의 일정부위 만큼 상기 너얼링부(5)가 삽입 결합되고, 또한 단자핀(3)의 돌출부위상에도 너얼링부(5)가 형성됨으로써 이에 권선되는 코일(4)은 단자핀(3)에서 쉽게 풀려지지 않음은 물론, 상기 핀 삽입구멍(2)내에 삽입 고정된 단자핀(3)이 쉽게 빠지지 않는다.Therefore, after the knurling portion 5 is formed on the intermediate portion of the terminal pin 3 of the low pressure bobbin 6, as shown in FIG. Is inserted and coupled, and the knurling portion 5 is also formed on the protruding portion of the terminal pin 3, so that the coil 4 wound around it is not easily released from the terminal pin 3, as well as the pin insertion hole 2. Terminal pins (3) inserted and fixed in the bracket do not come off easily.
상술한 바와 같이 본 고안은, 저압보빈단자의 단자핀 중간부위에 너얼링을 형성함으로써, 이부위에 권선되는 코일이 쉽게 풀려지지 않고, 이에따라 코일의 단선을 방지함은 물론, 단자핀이 핀 삽입구멍 내에서 쉽게 빠지지 않으므로서 제품의 신뢰도를 향상시킬 수 있는 잇점이 있다.As described above, the present invention forms a knurling on the middle of the terminal pin of the low-voltage bobbin terminal, so that the coil wound around this part is not easily released, thereby preventing disconnection of the coil, and of course, the terminal pin has a pin insertion hole. There is an advantage in improving the reliability of the product without being easily missed within.
