Abstract

The invention provides a microtransformer manufacturing method and the microtransformer. The manufacturing method includes: step 1 providing a terminal base with a fixed winding post; step 2 winding the first coil; step 3 sequentially completing the winding of other coils in the coil group; step 4 removing the winding post; step 5 assembling microtransformer. When the coil is wound, the present invention fixes the lead-out wire of the coil and the terminal of the wiring base together, so that it does not need to be fixed again after the coil is wound, and the operation is convenient and the process is simple.

Description

technical field

[0001] The invention relates to a manufacturing method of a miniature transformer and a miniature transformer manufactured by the method. Background technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components include a coil group and a magnetic core. Micro-transformers are widely used. Micro-transformers are required in various mobile phone chargers, small electric tools, and other tiny electrical and electronic products. In the micro-transformer, the coil group is an essential and important part, and the quality of the coil has a great influence on the quality of the micro-transformer. The air-core coil group has the advantages of simple structure, high inductance precision, small distributed capacitance, high self-resonant frequency, small temperature coefficient, good stability, and strong anti-interference ability.
