본 고안은 저압코일 권선용 보빈과 고압코일 권선용 보빈이 동일축상에 내,외삽되는 싱글 타입(SINGLER TYPE)플라이백 트랜지스포머에 있어서 1차코일과 2차, 3차코일이 각각 절연되는 2중절연식에 관한 것이다.The present invention is a double cut in which the primary coil, the secondary coil and the tertiary coil are insulated in a single type flyback transformer in which a bobbin for winding a low pressure coil and a bobbin for a high voltage coil are interpolated and extrapolated on the same axis. It's about the year.

통상의 텔레비젼 회로방식은 교류전원(AC)의 한 단자가 텔레비젼 회로의 어스가되는 핫샤시(HOT CHASSIC)로 되어 이 경우에 트랜스를 사용하여 핫회로를 콜드(COLD)화 시키므로 트랜스 설치공간이 별도로 필요하고 이에 따라 원가가 상승되며 특히 점차 다기능화됨에 따라 각 기능별로 구분된 트래스를 필요로 하므로써 이를 해결코져 플라이백 트랜스포머에서의 2중절연을 꾀하였고 그 구성은 제1도에 도시한 것과 같다.In general television circuit system, one terminal of the AC power supply is a hot chassis that is the earth of the television circuit. In this case, the transformer is used to make the hot circuit cold so that the transformer installation space is separate. As a result, the cost is increased and, in particular, as it becomes more multifunctional, it requires a separate trace for each function, which is designed to double insulation in the flyback transformer. The configuration is as shown in FIG. .

종래의 이러한 2중 절연식 구조중에 제1도의 (a)에 도시된 것을 살펴보면 통상의 저압보빈(1)에 평권부로 형성되게 1차 코일(1')을 권선한후 그 외측에 저압보빈(1)에 외삽되는 고압보빈(2)을 두어 2차코일(2')을 권선시키면서 저압보빈(1)의 일측에 보빈을 연장하여 별도의 좁은폭의 1차 저압코일(1'')권선부(1a)를 두고 그와주로 보조링(4)으로 절연구분되는 3차코일 권선부(3)를 두어 평권부인 1차코일(1')과 2차코일간(2')의 절연, 1차코일과 3차코일(3')간의 절연을 꾀한 2중절연 방식은 통상의 플라이백 트랜스포머의 구성에서 매우 간단히 콜드(COLD)부로 3차코일(3')을 권선할 수 있으나 저압코일 좌, 우측으로 중복 권선하여야 되고 3차코일 권선부(3)의 형성에 있어서 별도로 분리된 보빈이 아니고 저압코일 권선용 저압보빈(1)을 일측에 보조링(4)으로 구획되는 높은 플랜지부로 개조한 것인바, 저압 1차코일(1'')을 권선한후에 보조링(4)을 끼운후 3차코일(3')을 권선시켜야 되므로 매우 번거롭고 별도의 부속인 보조링(4)이 소요되는 단점이 있고, 제1도의 (b)에 도시된 것을 살표보면 통상의 저압보빈(1)과 그외주로 외삽되는 고압보빈(2)으로 형성된 것에 파이프형 보조보빈(4')을 저압보빈(1)과 고압보빈(2)사이에 삽입시켜서 이 보조보빈(4')에 3차코일(3')을 권선시켜된 구조인바, 이러한 것도 2중 절연 효과는 있으나 별도의 파이프형 보조보빈(4')이 부가되고 이에 따라 고압보빈(2)이 상대적으로 커지고 트랜스의 부피도 커지는 단점들이 있었던 것이다.Referring to the conventional double-insulated structure shown in (a) of FIG. 1, the primary coil 1 'is wound around the conventional low pressure bobbin 1 to form a flat portion, and then the low pressure bobbin ( 1) Winding the secondary coil (2 ') by extrapolating the high-pressure bobbin (2) to the bobbin on one side of the low-pressure bobbin (1) by winding a separate narrow primary low-pressure coil (1' ') winding (1a) with a third coil winding section (3) insulated by the auxiliary ring (4), and the insulation of the primary coil (1 ') and secondary coil (2'), the primary coil, the primary coil The double insulation method to insulate between the 3rd coil and 3rd coil can wind the 3rd coil 3 'with the cold part very simply in the configuration of a conventional flyback transformer. In the formation of the tertiary coil winding part 3, the high winding which separates the low pressure bobbin 1 for low pressure coil windings into the auxiliary ring 4 on one side should be repeated winding. It is a modified part of the flange, and after winding the low pressure primary coil (1 ''), the auxiliary ring (4) must be inserted and the third coil (3 ') must be wound, so the auxiliary ring (4) is very troublesome. There is a disadvantage in that it takes, and if you look at what is shown in (b) of FIG. Inserted between the (1) and the high-pressure bobbin (2) by winding the secondary coil (3 ') to the auxiliary bobbin (4'), this also has a double insulation effect, but a separate pipe type auxiliary bobbin ( 4 ') was added, and thus the high pressure bobbin 2 was relatively large and the volume of the transformer was large.

본 고안은 종래의 이와 같은 제반 2중절연 방식의 플라이백 트랜스포머를 개량하여 3차코일을 콜드(COLD)화 시킴에 있어서 별도의 보조보빈이 필요없이 1차코일의 절연, 2차코일과의 절연을 시키면서 3차코일 권선에 따른 출력단자를 여유있게 설치할 수 있도록 함에 목적이 있는 것으로 첨부된 도면과 함께 상세히 설명하면 다음과 같다.The present invention improves the conventional double-insulated flyback transformers to cold the tertiary coil and eliminates the need for an auxiliary bobbin, and insulates the secondary coil. While being described in detail with the accompanying drawings, the purpose is to allow the output terminal according to the winding of the third coil to be relaxed as follows.

저압 코일 권선용 저압보빈(1)이 중심에 위치하고 그 외주로 고압코일 권선용 고압보빈(2)이 외삽되어 케이스(6)에 내설되는 통상의 싱글타입 플라이백 트랜스포머에 있어서 케이스(6)의 외주면(6')에 수개의 돌편(7)을 등간격으로 환설하여 3차코일(3')을 권선시킬 수 있도록하고 외주면 하단부(6a)에 탭단자(8)을 수개 환설시켜서된 구성으로서 미설명 부호 (9)은 페라이트 코어, (10)은, 1, 2차 코일 탭단자를 나타낸 것이다.In the conventional single type flyback transformer in which a low pressure bobbin (1) for winding a low pressure coil is located at the center, and a high pressure bobbin (2) for high pressure coil winding is extrapolated and built into the case (6), the outer peripheral surface (6) of the case (6) It is configured to allow winding of the tertiary coil (3 ') by winding several pieces of stone (7) at equal intervals on the') and several tap terminals (8) on the lower end (6a) of the outer peripheral surface. 9 shows a ferrite core, and 10 shows a primary and secondary coil tap terminal.

이와 같은 구성의 본 고안은 플라이백 트랜스포머의 구성에 있어서 콜드부인 3차코일(3')을 케이스(6)의 외주면(6')에 권선시켜 형성하므로써 저압보빈(1)에서 권선된 1차코일(1')과 절연이 되므로써 종래와 같이 복잡한 보빈 개량 및 보조보빈의 첨가 없이 2중절연이 확실히 될뿐 아니라 이에 따라 원자재가 절감되고 작업공정이 단축되어 원가절감과 생성성을 증대시킬 수 있으며 3차코일 설치에 따라 요구되는 탭단자를 케이스(6)외주면 하단부(6a)에 형성시키므로써 여유있는 출력단자를 확보할 수 있는 장점이 있는 것이다.The present invention having such a configuration is formed by winding a third coil 3 ', which is a cold part, on the outer circumferential surface 6' of the case 6 in the configuration of the flyback transformer. As it is insulated from (1 '), double insulation is assured without complicated bobbin improvement and addition of auxiliary bobbin as in the prior art, and thus, raw materials can be saved, work process can be shortened, and cost reduction and productivity can be increased. The tab terminal required by the coil installation is formed in the lower end portion 6a of the outer circumferential surface of the case 6, so that there is an advantage of ensuring a sufficient output terminal.
