Abstract

The invention discloses a winding structure. The winding structure comprises a bobbin and conductive sheets; the bobbin is equipped with a through channel which lengthways passes through the bobbin; the conductive sheets are clamped on the bobbin; a pin which is welded to a circuit board extends from the lower end of each conductive sheet; a coiling slot is formed between every two adjacent conductive sheets; the coiling slots communicate with each other. According to the winding structure, the coiling slots are used for coiling copper wire; the coiling slots are intercommunicated, so that the copper wire can be arranged regularly, and as a result, the utilization rate of the copper wire is increased; in addition, the potential difference of the copper wires is relatively low; the winding process is simple; the manufacturing is convenient; the production is easy. The invention further provides a transformer assembly with the winding structure, and a transformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a winding structure, a transformer component and a transformer with the winding structure. Background technique [0002] Transformers are widely used in various electronic devices, using the principle of electromagnetic mutual induction to transform voltage, current and impedance. Generally, a transformer is composed of an iron core or a magnetic core and a coil. The coil has more than two windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. When an alternating current is passed through the primary coil, an alternating magnetic flux is generated in the iron core or magnetic core, which induces a voltage or current in the secondary coil. [0003] The currently known transformers include: bobbins, coils wound on the bobbins, core groups passing through the bobbin cores, housings for accommoda...
