摘要： The present invention relates to a transformer. In the transformer, secondary winding sections are placed in both sides of a primary winding section, all terminals of the secondary winding sections are used as output terminals, and an input terminal is placed in the opposite side to the output terminals. Therefore, a return wire in the high-voltage output side does not need to be provided, and a sufficient insulation separation distance is secured in the relation with a printed circuit board, which makes it easy to implement a circuit. Further, improved efficiency is obtained over a conventional transformer, there is a significant reduction in cost, and products using the transformer can be small in size. The transformer includes a bobbin composed of one primary winding section having one input terminal and one ground terminal and 2n (n: positive number) secondary winding sections, each secondary winding section having two output terminals; a primary coil wound around the primary winding section; secondary coils wound around the 2n secondary winding sections; and a pair of cores that are respectively inserted into an insertion hole formed inside the bobbin.
摘要翻译：变压器技术领域本发明涉及变压器。在变压器中，次级绕组部分放置在初级绕组部分的两侧，次级绕组部分的所有端子用作输出端子，输入端子放置在与输出端子相反的一侧。因此，不需要设置高压输出侧的回线，并且与印刷电路板的关系确保足够的绝缘隔离距离，这使得容易实现电路。而且，与以往的变压器相比，能够提高效率，成本显着降低，使用变压器的产品尺寸可以小。该变压器包括一个线圈，其由具有一个输入端子和一个接地端子的一个初级绕组部分和2n（n：正数）次级绕组部分组成，每个次级绕组部分具有两个输出端子; 缠绕在初级绕组部分上的初级线圈; 二次线圈缠绕在2n个次级绕组部分上; 以及分别插入形成在筒管内的插入孔中的一对芯。
