Communication transformer and winding method of winding set thereof

Abstract

The invention discloses a communication transformer which comprises a framework and an iron core. A winding groove is formed in the framework, a wound winding set is arranged in the winding groove of the framework, the winding set comprises a plurality of primary windings and a plurality of secondary windings, the primary windings and the secondary windings are arranged at intervals and are twisted to form the winding set, and the winding set is wound on the winding groove of the framework. The invention further discloses a winding method of the winding set of the communication transformer. The winding set is arranged in the winding groove of the framework, the winding set comprises the primary windings and the secondary windings, the primary windings and the secondary windings are arranged at intervals and are twisted to form the winding set, the twisted secondary windings and primary windings are fully and closely combined, the leakage inductance between the primary windings and the secondary windings is small, the leakage flux loss of the transformer is lowered, the phenomenon that the energy of communication signals is severely attenuated after the communication signals pass through the transformer is solved, and the transmission performance of the communication transformer is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a communication transformer and a winding method for a winding group thereof. Background technique [0002] Communication transformers, also known as communication isolation transformers, or data mercury, are mainly used in network switches, routers, network cards, and hubs to perform signal coupling, signal transmission, high-voltage isolation, waveform repair, impedance matching, signal clutter suppression, voltage Isolation, electromagnetic interference suppression, etc. [0003] There are generally two winding methods for the winding group of traditional communication transformers: ordinary layered winding and sandwich winding, and the layers are separated by tape. However, the transformer obtained by the above-mentioned winding method has poor coupling between the primary and secondary stages, which leads to severe energy attenuation of communication signals after pass...

AI Technical Summary

Problems solved by technology

However, the transformer obtained by the above-mentioned winding method has poor coupling between the primary and secondary stages, which leads to severe energy attenuation of communication signals after passing through the transformer when used in circuits, and it is prone to signal transmission interruption, which is difficult to control and has poor performance.
