Problems solved by technology
[0002] As one of the most widely used high-speed data transmission connectors, high-speed backplane connectors are currently widely used in the field of electronic communications. However, the method of transmitting signals through printed boards is likely to cause large signal crosstalk, incomplete return paths, and high-frequency Electromagnetic wave leakage causes problems such as large crosstalk between high-speed signals, which affects the transmission quality of high-speed signals. Therefore, it is necessary to optimize connectors with high-speed transmission printed boards to improve signal transmission quality

The invention discloses a high-speed backboard connector with crosstalk suppression printed boards. The backboard connector comprises a shell, a plurality of signal transmission printed boards which are longitudinally arranged and combined at intervals are arranged in the shell, each signal transmission printed board comprises a top layer, a middle layer and a bottom layer, the middle top layer is a differential wiring layer, the middle layer is an insulating substrate, and the bottom layer is a reference ground plane layer. The differential wiring layer is provided with a first high-speed differential signal group, a second high-speed differential signal group and metalized via holes, the metalized via holes surround the first high-speed differential signal group and the second high-speed differential signal group, and signals between the first high-speed differential signal group and the second high-speed differential signal group are isolated through GND (reference ground); and the GND (reference ground) is connected with the reference ground plane layer through a metalized via hole to form a complete isolation and signal loop. The signal transmission printed boards are adopted for wiring, and the golden fingers at the two ends of the signal transmission printed boards are of a full-shielding structure, so that crosstalk is further reduced, and the signal transmission quality is improved.
