본 고안은 플라이백 트랜스포머의 저압보빈에 관한 것으로 특히, 저압보빈의 하부에 형성되는 터미널단자 고정대의 개량에 관한 것이다.The present invention relates to a low pressure bobbin of a flyback transformer, and more particularly, to an improvement of a terminal terminal holder formed on a lower portion of a low pressure bobbin.

종래의 플라이백 트랜스포머의 저압보빈은 여러 종류의 것이 제공되어 있는바 그 구조는 제 1 도에 도시한 바와 같이 대부분의 것이 상부로 보빈동체(1)가 형성되고 페라이트코어 격리대(2)가 형성되며 그 외주로는 다소 큰 직경의 원호상 터미널단자 고정대(3)가 수개 배설되어 있다.The low-pressure bobbin of the conventional flyback transformer is provided with a variety of types, the structure of which most of the bobbin body (1) is formed in the upper portion as shown in Figure 1 and the ferrite core isolator (2) is formed As the outer circumference, several large arc-shaped terminal terminal holders 3 are arranged.

상기 동체(1) 외주면으로는 저압코일이 권선되고 그 외주로는 다시 고압코일이 권선되는 고압보빈이 관삽되어 각각의 저, 고압 코일의 리드선(5)이 하부에 고정배설된 수개의 터미널단자(7)에 연결되는바, 종류에 따라서는 저압코일 권선부로 동체(1)의 하측과 고정대(3)사이에 좁은 폭으로 되고 직경이 다소 큰 별도의 저압코일권선용 기권부(4)가 형성되어 있다.The outer circumferential surface of the fuselage 1 is a low-pressure coil is wound, and the outer circumference is a high-pressure bobbin which is wound with a high-pressure coil. 7) is connected to the low pressure coil winding, depending on the type is formed between the lower side of the fuselage 1 and the stator (3) of a narrow width and somewhat large diameter low pressure coil winding winding portion (4) is formed. .

이러한 구성의 저압보빈은 보빈 동체(1)와 터미널단자 고정대(3) 및 격리대(2)가 단일체의 합성수지제로 사출성형되고 고정대(3)의 핀홀(6)에 압입고정되는 터미널단자(7)는 금속제로 되어 자동기계로 일괄 조립되어 형성되는바, 각각의 저압코일 권선 과정을 살펴보면, 먼저 터미널 부에 저압코일의 시작선을 권선한 후, 상부로 연장하여 소정의 위치에서 동체 외주로 적정횟수로 권선한후 끝선은 다시 해당 터미널단자에 권선되고, 또 기권부(4)에도 동일한 방법으로 저압코일이 권선되어 저압 보빈이 완성되며, 이 완성된 저압보빈의 동체(1)외주면에는 공지하는 바와 같이 고압코일이 권선된 고압보빈이 삽입되어 그 리드선(5)이 해당 터미널단자(7)에 각각 배선되는 것이다. 이러한 조립공정(권선공정)을 실시함에 있어서 상기한 종래의 터미널단자 고정대(3)는 각각 터미널단자(7)를 고정시키면서 저, 고압코일의 리드선(5)고정작용을 하고 그 상측단(3a)은 기권부(4)와 경계를 이루는 경계면으로 구성되므로 제 1 도에 도시한 바와 같이 상측단(3a)의 모서리(3b)가 직각에 가까운 예리한 형태로 형성되면 권선불량이 초래된다.The low pressure bobbin of this configuration has a terminal terminal (7) in which the bobbin body (1), the terminal terminal holder (3), and the isolation member (2) are injection molded from a single piece of synthetic resin and press-fitted into the pinhole (6) of the holder (3). Is made of metal and is assembled and assembled by automatic machine. Looking at the process of winding each low pressure coil, first, winding the start line of the low pressure coil in the terminal part, and then extending upward to the appropriate number of times around the fuselage at a predetermined position After winding, the end line is again wound on the corresponding terminal terminal, and the low-pressure coil is wound in the winding section 4 in the same way to complete the low-pressure bobbin, and the outer circumferential surface of the completed low-pressure bobbin body (1) is known as The high-voltage bobbin wound around the high-voltage coil is inserted, and the lead wires 5 are respectively wired to the corresponding terminal terminal 7. In performing such an assembling process (winding process), the above-described conventional terminal terminal holder 3 fixes the lead wire 5 of the low and high pressure coil while fixing the terminal terminal 7, respectively, and the upper end 3a thereof. Since is composed of a boundary surface forming a boundary with the winding portion 4, as shown in FIG. 1, when the edge 3b of the upper end 3a is formed in a sharp shape close to a right angle, winding failure occurs.

즉, 고정대(3) 하측단(3c)에서 터미널단자(7)에 코일리드선(5)을 감아 고정한 후 고정대의(3)의 외향으로 밀착시키면서 기권부(4)로 저압코일을 감는 자동권선 공정에 있어서, 고정대(3)의 상측단(3a)측에서 예리한 모서리(3b)에 코일이 간섭되어 불량권선이 되거나 경우에 따라서는 단선이 되고, 동체(1)에 저압코일을 권선한후 인출선을 재차 해당 터미널단자에 배선할 때에도 상기한 바와 같이 예각의 모서리(3b)에 밀착되면서 터미널단자에 권선 됨으로써 코일의 피막이 벗겨지고 단선 우려가 있는 폐단이 있으며, 고정대(3)의 핀홀(6)형태가 하측단(3c)에서 상측단(3a)으로 갈수록 테이퍼 가공되어 있어서 터미널단자(7)가 압입되면 핀홀(6)내의 걸림부(6')가 상측단(3a)으로 밀려 올라가 이물질 부재(6a)로 형성되므로써 또 다른 기권부(4)의 권선불량을 야기하는 단점들이 있었던 것이다.In other words, after winding the coil lead wire 5 to the terminal terminal 7 at the lower end 3c of the fixing stand 3, the automatic winding process of winding the low-pressure coil to the winding portion 4 while being in close contact with the outside of the fixing stand 3 is carried out. In the upper end (3a) of the stator (3), the coil is interfered with the sharp edge (3b) to become a bad winding or, in some cases, disconnection, winding the low-pressure coil to the body (1) When wiring to the terminal again, as described above, the coil is peeled off and close to the edge 3b of the acute angle, so that the film of the coil is peeled off and there is a closed end that may be disconnected, and the pinhole 6 of the fixing stand 3 is formed. Is tapered from the lower end 3c to the upper end 3a. When the terminal terminal 7 is press-fitted, the engaging portion 6 'in the pinhole 6 is pushed up to the upper end 3a, and the foreign material member 6a is pressed. To cause winding failure of another winding section 4 by There were dots.

이에 본 고안은 상기한 종래의 제반문제점을 해결코자 안출한 것으로, 코일의 권선불량 및 단선을 방지코함에 그 목적이 있는 것이다.Therefore, the present invention has been made to solve the above-mentioned general problems, and its purpose is to prevent winding failure and disconnection of the coil.

이하 본 고안의 구성을 첨부된 도면과 관련하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

상부로 보빈동체(1)가 형성되고 하부로 기권부(4)와 페라이트코어격리대(2)가 형성되며, 그 외주로는 터미널단자(7)가 테이퍼진 핀홀(6)에 삽착 고정되어지는 원호상의 고정대(3) 수개가 일체로 형성된 저압보빈에 있어서, 기권부(4)와 대향지는 고정대(3)의 상측단(3a)을 외측으로 하향경사면(3a')이 되게 가공하여 모서리(3b')를 둔각처리 되게 한 구성으로, 도면중 미설명 부호(3c)는 고정대(3)의 하측단, (5)(5')는 리드선, (6')는 테이퍼진 핀홀(6)의 걸림부이다.The bobbin body 1 is formed in the upper portion, and the winding portion 4 and the ferrite core isolator 2 are formed in the lower portion thereof, and the terminal circumference is inserted into and fixed to the tapered pinhole 6. In the low-pressure bobbin which is formed integrally with a plurality of arcuate fixing stands 3, the upper end portion 3a of the fixing stand 3 is machined outward so as to be a downwardly inclined surface 3a 'to the edge 3b. In the drawing, reference numeral 3c is a lower end of the fixing base 3, (5) and 5 'are lead wires, and 6' is a tapered pinhole 6, respectively. It is wealth.

위와 같이 구성된 본 고안은 고정대(3)의 폭이 평판의 상측단(3a)에서 하향경사면(3a')으로 가공되어 점차 깎여지므로 핀홀(6)의 길이도 단축되어 하측단(3c)에서 터미널단자(7)에 압입될 때 테이퍼진 핀홀(6)의 걸림부(6')가 극히 짧은 길이에 걸쳐서만 밀리므로 경사면(3a')에의 이물질 층의형성이 방지되고 제 5 도에서 도시한 바와 같이 기권부(4)에의 저압코일 권선공정에 있어서도 하측단(3c)의 터미널단자(7)에 코일리드선(5)을 일차감아 배선한 후 고정대(3)의 외향으로 모서리(3b')와 경사면 (3a')에 밀착시키면서 기권부(4)에 권선시키므로 둔각으로 된 모서리(3b')에서 피막의 손상 및 절단을 방지하면서 외향으로부터 기권부(4)로 감아지는 리드선(5')이 모서리(3b')에 간섭됨이 없이 경사면(3a')에서 기권부(4)측으로 미끄러지면서 원활하게 안착되는바, 제반 권선 불량을 효과적으로 해결하여 작업능률의 증대 및 제품의 신뢰성을 한층 높여 줄 수 있는 장점을 갖는 바이다.According to the present invention configured as described above, the width of the holder 3 is gradually cut from the upper end 3a of the flat plate to the downward inclined plane 3a ', so that the length of the pinhole 6 is also shortened so that the terminal terminal at the lower end 3c. Since the locking portion 6 'of the tapered pinhole 6 is pushed only over an extremely short length when pressed into (7), formation of a foreign material layer on the inclined surface 3a' is prevented and as shown in FIG. Also in the low-pressure coil winding process to the winding portion 4, the coil lead wire 5 is wound around the terminal terminal 7 of the lower end 3c and wired first. 3a ') is wound around the winding portion 4, so that the lead wire 5' wound from the outward direction to the winding portion 4 is prevented from damaging and cutting the film at the obtuse corner 3b '. It is smoothly seated as it slides from the inclined surface 3a to the winding portion 4 side without interfering with '). Bayida has the advantage to effectively address the poor that will further enhance the reliability of the product and increase the work efficiency.
