Therefore, the height of the product is increased by the dimension c of the brim.
かつ、ボビン３の成形金型が３方向抜き構造となり複雑
で、金型製作に長時間を要し、成形樹脂量も多く取個数
も少なくなり、コスト高であるという問題点があった。In addition, the molding die of the bobbin 3 has a three-direction drawing structure and is complicated, and it takes a long time to manufacture the die, the amount of the molding resin is large, the number of pieces is small, and the cost is high.
本発明はこのような問題点を解決するもので、トランス
の高さを低くしかつ、ボビン構造を簡単にし、金型コス
ト、ボビンコストを低減し、小型軽量で、ローコストの
トランスを提供することを目的とするものである。The present invention solves such a problem, and provides a transformer that is low in height and simplifies the bobbin structure, reduces mold cost and bobbin cost, is small and lightweight, and is low cost. The purpose is.
問題点を解決するための手段 この問題点を解決するために本考案は、胴体部の一方に
のみ鍔を有し、その鍔に端子ピンを埋設したボビンを備
え、上記ボビンの胴体部に下巻を幅広く上巻きになる程

している。Means for Solving the Problems In order to solve this problem, the present invention has a bobbin having a collar only on one side of the body, and a bobbin having a terminal pin embedded in the collar. The winding width is narrower as the winding becomes wider and the magnetic core is incorporated into the bobbin.
作用 この構成により、トランスの高さを低く設計でき、かつ
ボビンの構造が単純になり、ボビン成形金型の製作も容
易になり時間の短縮、成形樹脂量の低減が可能となり、
小形ローコストのトランスを得ることができる。Function With this configuration, the height of the transformer can be designed low, the structure of the bobbin is simple, the bobbin molding die can be easily manufactured, and the time and the amount of molding resin can be reduced.
A compact, low-cost transformer can be obtained.
実施例 以下、本考案の実施例を添付の図面第１図〜第３図を用

トランスの完成外観図である。FIG. 3 is a block diagram of a bobbin according to an embodiment of the present invention. Reference numeral 5 is a terminal, 6 is a body portion for supporting the winding, 7 is a collar provided at the lower end of the body portion 6, which also serves as a terminal supporting portion necessary for burying the terminal, and 8 is a position of the winding. It shows a stepped portion provided with a step from the body portion 6 so as not to cause a deviation. Next, FIG. 1 is a sectional view of the transformer of the present invention, in which 9 is an EI type magnetic core made of ferrite or the like, and 10 is the bobbin described above. Here, the winding wire 11 is wound from the stepped portion 8 of the bobbin 10 and wound so that the dimension b is inward from the end of the first layer to the second layer through the insulating tape 12 to form a coil. Similarly, the other windings are also wound from the inside of the lower winding to form a pyramid-shaped winding as shown by a broken line, and have a winding configuration that prevents line collapse. FIG. 2 is a completed external view of the transformer.
考案の効果 以上のように本考案によれば、従来例に比較してボビン
の一方の鍔をなくすとともに、ボビンに上巻きになる程
巻幅を狭く巻線したことから、巻線の線くずれを生じる

個数の増加などが可能となり、低コストのトランスが得
られるという効果がある。As described above, according to the present invention, one side of the bobbin is eliminated as compared with the conventional example, and the winding width is narrowed so that the bobbin is wound more upward. It is possible to reduce the height of the transformer without causing any damage, and the bobbin structure can be simplified, and the bobbin molding die has a two-way punching structure, which shortens the processing time, reduces the amount of molding resin, and increases the number of pieces to be taken. It is possible to obtain a low-cost transformer.
