Description

  The present invention relates to a biaxial iron core thin transformer configuration, and more particularly to a transformer configuration having a biaxial iron core on the base surface at the same time.

  In recent years, technology technology has developed dramatically, especially in the field of microelectronics, and the technological fields have advanced every day, so electronic products have already penetrated our lives and various fields, and are now indispensable to modern society. It is not a thing.

  Since an electronic product needs to be operated with one output voltage, generally, the input voltage used in Japan is 200V unless it is 100V. If it is used as it is, the electronic product may be damaged. It must be used after stepping down through a transformer. Therefore, the transformer has become an electronic component that must be present in electrical equipment.

  Referring to FIG. 1, a schematic diagram of a three-dimensional configuration showing a conventional transformer is shown. The transformer 1 mainly includes a magnetic core assembly 11, a bobbin 12, a primary winding coil 13, and a secondary winding coil 14 (secondary winding coil). Among them, the primary winding coil 13 and the secondary winding coil 14 are wound up and down so as to overlap the winding coil portion 121 of the bobbin 12, and are insulated by, for example, an insulating tape 15 (isolation tape).

Since they substantially overlap and are substantially parallel to the plane 120 defined by the bobbin 12, the primary winding coil 13 and the secondary winding coil 14 substantially overlap each other in the extending direction of the shaft center portion 111a and the shaft center portion 112a. The axis can be wound only in the direction, and the volume and height H of the transformer 1 are increased.
