[0001] The utility model relates to the technical field related to connectors, in particular to a fully enclosed high-speed backplane connector. Background Art

[0002] High-speed backplane connectors are part of a typical electronic system, physically connecting modules. Complex systems rely on the wires, traces, and connectors on the backplane to handle large amounts of high-speed data flows. High-speed backplane connectors play a vital role in communication between multiple backplane modules. However, due to structural limitations, high-speed backplane connectors can cause significant crosstalk between differential signal pairs, significantly impacting signal transmission quality. As backplane connector transmission rates increase, existing high-speed backplane connectors require a robust return path and minimize crosstalk. Each differential pair in existing high-speed backplane connectors is independent of each other, making crosstalk more likely to occur. This results in poor high-speed signal transmission stability.
