Separated network transformer and transformation equipment

Abstract

The invention discloses a separated network transformer and transformation equipment. The split network transformer comprises at least one transmission element group for connecting a network chip and a network connector. And each transmission element group comprises a common mode inductor, a differential mode inductor, a first capacitor, a second capacitor, a third capacitor and a fourth capacitor. And the common-mode inductor is coupled with the network chip and is connected with the network connector through the third capacitor and the fourth capacitor so as to play a role in common-mode suppression and filtering. And the first capacitor and the second capacitor are coupled between the common mode inductor and the grounding end to play a role in filtering protection. The third capacitor and the fourth capacitor play a role in signal coupling and direct current isolation during signal transmission. The differential mode inductor is coupled between the network connector and the grounding end and plays a role in signal coupling and lightning surge protection, so that the stability and the reliability of the network transformer are improved.

Description

technical field [0001] The present application relates to the technical field of transformers, in particular to a separated network transformer and transformer equipment. Background technique [0002] In modern society, networks are ubiquitous, and network terminal equipment can be seen everywhere, such as routers, switches, network card communication base stations and so on. Generally, a network transformer is connected behind the network port of the terminal device. Network transformer is also known as network isolation transformer, or data mercury, it is mainly used between the transceiver chip and the RJ45 interface, it plays the role of signal coupling, high voltage isolation, impedance matching, electromagnetic interference suppression and so on. [0003] With the commercialization of 5G and the construction of the Internet of Things, networked devices and traffic data are skyrocketing, and the update speed of network communication devices is also unstoppable.

AI Technical Summary

Problems solved by technology

Traditional magnetic ring network transformers are mostly made by hand, with poor product consistency and hidden quality hazards, which make the stability and reliability of network transformers poor. Moreover, their production capacity is greatly affected by labor force, and the delivery stability is poor, which can no longer meet the needs of the industry.
