Problems solved by technology

[0002] High-speed electrical connectors are used to support high-performance applications. Signal shielding and integrity are the key to the entire design; in one-end connectors, the main design is to match the system impedance with the entire connector; impedance matching is the most important part of the transmission signal. Important parameters, such as impedance mismatch, will cause serious signal crosstalk during high-speed signal transmission, unstable signal transmission, and degraded quality;
[0003] High-speed electrical connectors used to support high data rates often use several differential signal pairs. The shielding components in the current connectors do not completely shield the differential signal pairs, and the shielding cost is high; and when connecting, the system impedance will appear differently. The situation of matching will eventually cause the stability and quality of the signal to decline
