* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 코일필름 11 : 절연재1: coil film 11: insulation material
12 : 코일막 13 : 평만금속단자핀12: coil film 13: flat metal terminal pin
본 고안은 전자렌지용 고압트랜스에 관련된 것으로서, 이는 특히 트랜스의 1차코일 보빈축에 권선되는 리즈코일의 사용에 의한 불리함을 제거하기 위한 대용 코일필름으로 구성되는 트랜스에 관한 것이다.The present invention relates to a high-voltage transformer for a microwave oven, and more particularly, to a transformer composed of a substitute coil film for eliminating the disadvantages caused by the use of a reel coil wound on the primary coil bobbin shaft of the transformer.
전자렌지용 고압트랜스는 근자에 이르러서 무겁고 부피가 크며 전력손실이 큰 규소강판의 트랜스 대신 고주파스위칭회로를 사용함에 의해 페라이트 코어에 의한 트랜스로서 부피나 무게를 경감시키며 전력소모를 줄이도록하는 노력이 증가되고 있다.Microwave high voltage transformers use high frequency switching circuits instead of silicon steel sheets, which are heavy, bulky, and high power loss, to reduce the volume, weight, and power consumption of ferrite cores. It is becoming.
그리고, 이러한 페라이트코어의 트랜스사용은 비교적 고주파로 구동되는 트랜스의 1차코일의 표피효과를 야기시키게 되므로서 단일의 코일도선을 이용하지 못하고 대가가 수집가닥의 소직경 세선을 가닥으로 꼬아서 되는 리즈와이어(3)를 제1도와 같은 1차측보빈(2)에 권선하여 단자부(4)로 유인하여 사용하는 것이 보통이다.In addition, the use of the transformer of the ferrite core causes the skin effect of the primary coil of the transformer driven at a relatively high frequency, so that a single coil wire cannot be used, and the cost is twisted by twisting a small diameter wire of the collecting strand into a strand. It is common for the wire 3 to be wound on the primary side bobbin 2 as shown in FIG. 1 and attracted to the terminal portion 4 for use.
그러나, 이러한 종래에의 트랜스 1차코일로의 리즈와이어(3)는 그 제작이 용이한 공정으로 이뤄지는 것이 아니므로 그 제작작업에의 불리함이 존재하고 있을뿐아니라 그 굵기가 비교적 굵으므로 인한 그 권선작업에의 곤란함도 문제가 되어왔다However, since the lead wire 3 of the conventional trans primary coil is not produced in an easy process, the disadvantage of the manufacturing work exists and the thickness thereof is relatively thick. Difficulties in winding work also have been a problem
이외에도, 상기 리즈와이어를 사용한 트랜스는 그 자체의 부피도 증가되므로 바람직한 것이 못되었다.In addition, the transformer using the wire is not preferred because the volume itself increases.
고안의 목적은 종래의 상기와 같은 트랜스의 1차측코일로 리즈와이어 사용에 의한 문제점을 개선하고자 한 것이다.The purpose of the invention is to improve the problems caused by the use of the lease wire as the primary side coil of the conventional transformer as described above.
본 고안은 특히 상기 리즈와이어가 박막의 코일필름으로 되어 구성되는 고압트랜스를 제공코져 한 것이다.The present invention is to provide a high-voltage transformer, in particular, the lead wire is composed of a thin coil film.
이하에서 이를 좀더 구체적으로 설명하면 다음과 같다.Hereinafter, this will be described in more detail.
즉, 본 고안은 제1도와 같은 고압트랜스의 구성으로 된다. 여기서는 1차측 보빈(2)에 단지 코일필름(1)이 적층권회된 형태로 되고, 이 코일필름(1)내측에서 평판금속단자핀(13)을 접합하여 외부로 인출한 구성으로 된다. 또, 상기 코일필름(1)은 제3도와 같이 띠상의 절연재(11)일측 표면에 수십 ㎛ 정도의 단면두께를 가지는 금속코일막(12)을 피층접합시킨 구성으로 되고, 이 코일막(12)은 역시 리즈선의 전체유효 단면적과 비례한 만큼의 두께로 주어지는 것이다. 이러한 구성의 본 고안은 이러한 고압트랜스의 1차측보빈(2)의 외주면에 코일필름(1)을 소망하는 만큼 적층권회한다.That is, the present invention has the configuration of the high voltage transformer as shown in FIG. Here, only the coil film 1 is laminated and wound on the primary bobbin 2, and the flat metal terminal pin 13 is bonded to the coil film 1 and drawn out. In addition, the coil film 1 has a structure in which a metal coil film 12 having a cross-sectional thickness of about several tens of micrometers is formed on the surface of one side of the band-shaped insulating material 11 as shown in FIG. Is also given as a thickness proportional to the total effective cross-sectional area of the line. The present invention of such a configuration wound the coil film 1 on the outer circumferential surface of the primary side bobbin 2 of such a high voltage transformer as desired by lamination.
이때는 상기 코일필름(1)의 코일막(12)과 평판금속단자핀(13)을 접합시킨 상태에서 그 평판금속단자핀(13)을 단자부(4)축으로 인출하여 위치시킨다. 도, 상기 코일필름(1)이 적층권회되었을때는 코일막(12)과의 사이에의 절연재(11)로 그 층간절연이 이뤄지게 된다. 또, 작업성면에서도 하나의 띠상코일필름(1)을 단지 1차측보빈(2)상에 감아주는 것이므로 그 작업의 난이도는 없게 된다. 또, 사용주파수가 고주파로 상승될때는 1차권선부의 발열이 증가되는데 넓은 평판면의 코일막(12)에 의해 강제방열등에 유리하게 작용할 수 있다.At this time, in the state where the coil film 12 and the flat metal terminal pin 13 of the coil film 1 are bonded to each other, the flat metal terminal pin 13 is pulled out and positioned on the terminal 4 axis. In addition, when the coil film 1 is laminated and wound, the interlayer insulation is performed by the insulating material 11 between the coil film 12 and the coil film 12. In addition, in terms of workability, since only one stripe coil film 1 is wound on the primary side bobbin 2, there is no difficulty of the work. In addition, when the use frequency is raised to a high frequency, the heat generation of the primary winding portion is increased, which may advantageously act for forced heat radiation by the coil film 12 having a wide flat surface.
