Problems solved by technology

Since the enameled wire wound around the hollow coil group is very thin, and the hollow coil group is also small, it is easy to tear off the wire end when binding and fixing the wire end on the terminal post, and the hollow coil group has multiple coil lead-out wires, which can be used in a small space. Fixing one coil lead wire may affect the connection between the other coil lead wire and the terminal, which is very inconvenient to operate
In addition, the length of the wire head of the coil lead-out wire will also affec

Abstract

The invention provides a miniature transformer manufacturing method and a miniature transformer. The manufacturing method comprises the following steps: 1, providing a wiring base fixed with a wrapping post; 2, winding a first coil; 3, sequentially completing winding of other coils in the coil assembly; 4, removing the wrapping post; and 5, assembling a miniature transformer. When the coil is wound, the coil leading-out wire and the binding post of the wiring base are fixed together, so that the coil does not need to be fixed again after being wound, 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. [0003] Existing micro-transformers using hollow coil g...
