본 고안은 라디오 카세트용으로 사용되는 변압기와 같은 소형의 교류전원 변압기의 안전을 위한 소형변압기용 보호커버에 대한 것이다.The present invention relates to a protective cover for a small transformer for the safety of a small AC power transformer such as a transformer used for a radio cassette.

종래에 사용하던 소형변압기는 제3도에 도시된 바와같이 1차측 코일을 비닐제로된 접착 테이프로 1-2회 정도 감아서 절연을 하였으나 1차 코일과 코 어간의 안전거리의 유지가 어려으므로, 감전의 위현이 많은 폐단이 있었으며 또 제조시 테이프를 감는 작업이 번거로워 가공생산능률이 저하됨은 물론 프린트 기판의 회로설계에서는 각나라별 안전규격에 맞는 설계를 해야되고 또한 재질에도 규제를 받고 있어 설계상 많은 어려움이 있었다.As the conventional small transformer is insulated by winding the primary coil 1-2 times with vinyl adhesive tape as shown in FIG. 3, the safety distance between the primary coil and the core is difficult to maintain. There was a lot of dangers of electric shock, and the process of winding the tape during manufacturing made it difficult to reduce the processing and production efficiency. In addition, the circuit design of the printed circuit board had to be designed to meet the safety standards of each country. There were many difficulties.

본 고안은 이와같은 점들을 해결하기 위해 개구된 전면의 상단에 1차리드선 배출구가 형성된 보호커어버를 성형하여 1,2차코일을 권취한 보빈이 씌워지게 결합하므로 간단히 코일과 코어가 절연되도록 하고 1차리드선을 쉽게 인출하여 AC전원 소켓에 연결할 수 있도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다. 1차코일(3)과 2차코일(3')의 권취부 간격(a), (b)을 각기 다르게 격리하는 격판(2)에 단턱(2')을 형성하고 1차코일측 외면판 상단에 반원형 인출홈(4)을 양측에 요설한 보빈(1)을, 전면 개구부(5)상단에 인출홈(4')이 양측에 요설되고 내면에는 안내돌기(6)가 양측에 종설된 감착부(7)를 형성한 커저(8)에 감착한 후 코어(9)를 감착부(7)외면에 끼워서 된 것이다.The present invention is to form a protective cover formed with a primary lead wire outlet on the upper end of the open front to solve these points, so that the bobbin wound around the first and second coils are covered so that the coil and the core are simply insulated. It is designed to easily draw the primary lead wire and connect it to the AC power socket. Steps 2 'are formed on the diaphragms 2 separating the winding gaps a and b of the primary coil 3 and the secondary coil 3' from each other, and the upper side of the primary coil side faceplate. The bobbin 1 having the semicircular withdrawal groove 4 on both sides, and the fitting portion having the withdrawal groove 4 'at the top of the front opening 5 on both sides, and the guide protrusion 6 arranged on both sides on the inner surface. After attaching to the cursor 8 which formed (7), the core 9 was fitted to the outer surface of the attachment part 7.

미설명부호 "10"은 1차 리드선이며,Unmarked "10" is the primary lead,

"11"은 종래제품에 절연을 위해 사용한 절연테이프이다."11" is an insulation tape used for insulation in conventional products.

이와같이 된 본 고안의 조립상태를 설명하면 다음과 같다.Referring to the assembly state of the present invention made as described above are as follows.

간격(a), (b)이 각기 다르게 형성된 권취부에 1,2차코일(3), (3')을 권취한 보빈(1)을 커버(8)의 감착부(7)에 끼워지게 조립하면 감착부(7)의 양측내면에는 안내돌기(6)가, 보빈(1)의 격판에 형성된 단턱(2')의 위치에 맞도록 종설되어 있어, 1,2차코일(3), (3')이 항상 제자리에 있도록 결합이 된다.The bobbin 1 wound around the primary and secondary coils 3 and 3 'is formed to be fitted to the fitting part 7 of the cover 8 by a winding part having a different gap (a) and (b). Guide protrusions 6 are arranged on both side inner surfaces of the lower surface attaching portion 7 so as to correspond to the position of the step 2 'formed on the diaphragm of the bobbin 1, and the primary and secondary coils 3, 3 Are combined so that ') is always in place.

이때 1차리드선(10)은 보빈(1)의 외면판 상단에 요설된 인출홈(4)과 감착부(7)의 전면 개구부(5) 상단에 요설한 인출홈(4)을 통해 외부로 인출하여 AC전원 소켓에 연결하도록 하며, 보빈(1)을 결합한 후에는 감착부(7)외면에 제2도와 같이 코어(9)를 끼우면 변압기의 조립이 완료되는 것이다.At this time, the primary lead wire 10 is drawn out to the outside through the withdrawal groove 4 concave on the upper surface of the bobbin 1 and the withdrawal groove 4 concave on the top of the front opening 5 of the fitting portion 7. To connect to the AC power socket, and after the bobbin (1) is coupled to the core (9) as shown in FIG.

이와같은 방법으로 조립하는 본 고안은 1,2차코일(3, (3') 사이와 또 이들과 코어(9)간의 절연이 종래와 같이 절연테이프(11)를 사용하지 않고도 간단히 이루어지며, 또 인출홈(4), (4')을 통해 1리드선을 쉽게 인출하여 소켓에 연결할 수 있으므로, 종래의 소형변압기에서 문제가되던 안전규격에 맞는 설계상의 많은 어려움도 간단히 개설할 수 있으며 가공 생산능률이 향상되는등 매우 실용적인 고안이다.The present invention to be assembled in this way is simple to insulate between the primary and secondary coils 3 and 3 'and between them and the core 9 without using the insulating tape 11 as in the prior art. Since the lead wire can be easily drawn out and connected to the socket through the drawing grooves (4) and (4 '), it is possible to simply establish many difficulties in design that meet the safety standard, which is a problem in the conventional small transformers. It is a very practical design.
