[0052] Figure 16 This is a return loss trend diagram of a high-speed electrical connector provided in this embodiment of the invention at frequencies from 0GHz to 40GHz. Figure 16 As shown, the relationship between the return loss (RL) of the five differential ports in this high-speed electrical connector and the simulation frequency was obtained through simulation. The horizontal axis represents frequency (unit: GHz), and the vertical axis represents return loss (unit: dB). ① is the standard line for 112G, and ② is the standard line for GENZ5. A larger absolute value of the return loss indicates better return loss and fewer impedance discontinuities in the connector. Figure 16 It can be seen that when the frequency is in the range of 0GHz-30GHz, the absolute value of the return loss of the five differential ports is relatively large (greater than 15dB), indicating that the return loss of the connector is good in this frequency range. When the frequency is in the range of 30GHz-40GHz, the change in return loss tends to be gradual as the frequency increases. It can be seen that the high-speed electrical connector provided by this embodiment has a more continuous impedance and better signal integrity.
