Background

Electromagnetic Interference (EMI) refers to an Interference phenomenon generated after Electromagnetic waves and electronic components act, and includes two types, namely conduction Interference and radiation Interference. Conducted interference refers to coupling (interfering) a signal on one electrical network to another electrical network through a conductive medium. The radiation interference means that an interference source couples (interferes) signals to another electric network through space, and in the design of a high-speed PCB and a system, a high-frequency signal line, pins of an integrated circuit, various connectors and the like can be radiation interference sources with antenna characteristics and can emit electromagnetic waves and influence the normal work of other systems or other subsystems in the system.

RJ45 is a connector for information sockets (i.e. communication outlets) in wiring systems, and the connector is composed of a plug (connector, crystal plug) and a socket (module), and the connector composed of these two components is connected between wires to realize the electrical continuity of the wires.

The existing network connector is composed of a shell, a support, terminals and LED lamps. In order to save space and increase transmission efficiency, most of the existing network connectors are of multi-group port structures, and metal isolation is not performed between the existing multi-group ports, so that certain electromagnetic interference exists between two adjacent groups of ports, and normal work of other systems or other subsystems in the system is influenced.
