Abstract

The invention relates to a transformer structure and a manufacturing method thereof. The transformer structure at least comprises a magnetic core, a coil winding, a coil reel and an insulation casing cover. The coil winding is provided with a primary side coil and a secondary side coil which wind on the coil reel and are integrated with the magnetic core, wherein a primary side input connection end and a reel clamping part are arranged on the coil reel. The insulation casing cover is provided with a first opening which is used for holding the magnetic core, the coil winding and the coil reel,a first sidewall which has a second opening for facilitating the output of the winding, a second sidewall which has a casing cover clamping part which is clamped with the reel clamping part, and a primary side output connection end and a secondary side output connection end. Therefore, the magnetic core of the transformer is effectively isolated from other elements so as to ensure electrical safety.

Description

technical field [0001] The invention relates to a transformer structure and a manufacturing method thereof, in particular to a transformer structure and a manufacturing method thereof which can effectively improve the electrical safety of the transformer with regard to magnetic core insulation. Background technique [0002] Transformers are widely used in various electronic devices, and are indispensable components for various power supply devices in transmitting and processing power. In order to meet the latest demands of the market, it is an inevitable design direction that the components of the electronic device are densely packed due to thinness, lightness, shortness and continuous improvement of the efficacy of the electronic device. How to reduce the size of the transformer to meet the above design trend has become an important issue in transformer design. [0003] see figure 1 and figure 2 , which shows a schematic diagram of decomposition and assembly of a tradit...
