Description

Technical Field

[0001] This invention belongs to the field of connector technology, and in particular relates to a network connector. Background Technology

[0002] Connectors are primarily used in computer peripherals, servers, routers, switching equipment, and other products for data transmission and peripheral connection, and are widely applied in networking, communication, and automation control. As electronic products become increasingly feature-rich and the market diversifies, the structural requirements for products are increasing, and the need for shielding and protection in connectors is becoming more widespread. This necessitates the addition of shielding and protective structures to connectors to achieve protective purposes.

[0003] As RJ45 network connectors become increasingly feature-rich, the requirements for RJ products are also increasing. In particular, structural compatibility is crucial to save on mold costs, as conventional designs cannot achieve this. Furthermore, EMI design demands isolation between the top and bottom ports, as well as the left and right ports. Conventional designs cannot directly insert isolation plates, resulting in either non-connectivity between the top / bottom or left / right ports. Summary of the Invention
