Problems solved by technology

[0002] At present, high-frequency transformers are usually wound with multiple coaxial cables according to the number of turns. After the power is turned on, the cables and the magnetic core will be heated due to the large current, which will cause the magnetic core to be broken; and there is a transformer volume Disadvantages such as large size, high quality requirements for coaxial cables, large distribution parameters of transformers, and difficulty in matching transformers and circuits

Abstract

The invention relates to a high-frequency transformer and a winding method thereof in the field of transformers. The high-frequency transformer comprises a magnetic core, and the magnetic core is provided with two through holes which are arranged side by side at intervals; the number of the conductive sleeves is two, and the two conductive sleeves respectively penetrate through the two through holes; the first cable is wound on the two conductive sleeves of the magnetic core, and the two ends of the first cable penetrate out of the different conductive sleeves on the same side of the magnetic core and are connected with the other conductive sleeve; the second cable is wound on the two conductive sleeves of the magnetic core, and the two ends of the second cable penetrate out of the different conductive sleeves on the same side of the magnetic core respectively. When the transformer is wound, distribution parameters can be reduced, so that matching between the transformer and a circuit is finer.

Description

technical field [0001] The present application relates to the field of transformers, in particular to a high-frequency transformer and a winding method thereof. Background technique [0002] At present, high-frequency transformers are usually wound by multiple coaxial cables according to the turns ratio. After the power is applied, the cables and the magnetic core will be heated due to the large current, and the magnetic core will be broken, and there is a transformer volume. Large, high quality requirements for coaxial cables, large distribution parameters of transformers, and difficulty in matching transformers and circuits. SUMMARY OF THE INVENTION [0003] In order to reduce the distribution parameters when winding the transformer and make the matching between the transformer and the circuit more precise, the present application provides a high-frequency transformer and a winding method thereof. [0004] In the first aspect, a high-frequency transformer provided by th...
