Transformer

Abstract

The invention provides a transformer, including an iron core group consisting of a first iron core and a second iron core, which are configured oppositely to form an containing space; a circuit board with a plurality of through-holes and located in the containing space; and a winding group located in the containing space, including an insulation coil with extension portions, each passes corresponding through the trough-holes; and a plurality of conductive sheets arranged in the insulation coil.

Description

technical field [0001] The invention relates to a transformer capable of miniaturization and cost reduction, in particular to a transformer conforming to safety regulations. Background technique [0002] Transformers are electronic components often used in various electrical equipment, such as figure 1 As shown, the existing transformer 1 includes a winding base 11 (bobbin), a coil assembly 12 , a pin base 14 and an iron core 13 . The coil set 12 includes a primary coil and a secondary coil, both of which are respectively wound on the winding base 11 by a conductive wire, and the primary coil and the secondary coil are electromagnetically coupled to each other. The iron core group is composed of a first iron core 131 and a second iron core 132. The first iron core 131 and the second iron core 132 are respectively sleeved on the two ends of the winding base 11 and joined with each other to form an electromagnetic circuit. [0003] Generally speaking, the coil group is made...

Therefore, a transformer 2 is additionally developed, such as figure 2 As shown, it uses a flat circuit board 22 with a spiral circuit to generate electromagnetic induction through an electromagnetic circuit structure formed by overlapping multiple circuit boards 22. Although it can reduce the volume of the transformer, it also greatly increases the components of the transformer. cost
