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

Abstract

The invention discloses a high-speed electric connector, which comprises a differential signal piece, wherein the differential signal piece comprises a first conductor and a second conductor which arearranged in a mirror symmetry mode, the first conductor comprises a first signal plate and a second signal plate, the first signal plate and the second signal plate are of an integrated structure, the first signal plate is arranged at the top of the second signal plate, the second signal plate extends out of a base, the second signal plate is connected with the base in an inserted mode, the central axis of the first signal plate and the central axis of the second signal plate are arranged in a staggered manner, and the staggered arrangement is used for matching an impedance value. According to the invention, the differential signal piece with staggered central axes is adopted, so that signal loss caused by impedance mismatching can be avoided, and the differential signal piece can be matched with the impedance value.
