AI Technical Summary

Technical Problem

When traditional electrical connectors transmit high-frequency signals, the transition structure at the end of the signal flare arm forms a "short line", which causes the signal to reflect, interfere with the normal signal, and affects the high-frequency performance.

Method used

An insulating block is provided on the signal flare arm of the signal terminal to cover the end of the signal flare arm, shorten the length of the transition part, shorten the length of the stub, and abut the blocked part through the elastic abutment arm to ensure stable contact of the first contact part.

Benefits of technology

By shortening the transition part at the end of the signal flare arm, the high frequency performance of the electrical connector is improved, the stable contact between the signal terminal and the docking element is ensured, and the signal terminal is shielded in the up and down directions to reduce crosstalk.

Abstract

The invention discloses an electric connector which is characterized in that the electric connector comprises a shell which is concavely provided with a butt joint groove along the front-back direction; two adjacent signal terminals form a differential signal terminal pair, at least one grounding terminal is located between two adjacent differential signal terminal pairs, each signal terminal comprises a signal elastic arm, the signal elastic arm comprises an elastic arm inner side and an elastic arm outer side far away from the butt joint groove, and the elastic arm inner side is provided with a first contact part exposed out of the butt joint groove; the insulating block is arranged on the signal elastic arm and wraps and fixes the tail end of the signal elastic arm, the insulating block comprises a blocked part, the blocked part is arranged on the outer side of the elastic arm, the end, away from the butt joint groove, of the grounding terminal bends and extends to form an elastic abutting arm, and the elastic abutting arm abuts against the blocked part. According to the signal terminal, the insulating block is arranged on the signal elastic arm of the signal terminal to wrap the tail end of the signal elastic arm, so that the transition part at the tail end of the signal elastic arm can be shortened, the stub is shortened, and the high-frequency performance is improved.
