Coupling terminal structure and electrical connector using the same

An electrical connector, comprising:

• a coupling terminal structure of an electrical connector and a dielectric housing, wherein the coupling terminal structure of an electrical connector includes:
• a plurality of first terminals and second terminals in pairs arranged side by side to form a terminal network;
• wherein the first terminal comprises a first contact portion, a first neck portion and a first extension portion;
• wherein the second terminal comprises a second contact portion corresponding to the first contact portion, a second neck portion corresponding to the first neck portion, and a second extension portion corresponding to the first extension portion;
• wherein the first contact portion and the second contact portion are arranged with a first distance there-between, the first extension portion and the second extension portion are arranged with a second distance there-between, the first distance is larger than the second distance, the first extension portion has a wide surface oriented toward a wide surface of the second extension portion such that electromagnetic coupling effect is generated between the first extension portion and the second extension portion;
• and
• wherein the terminal network is disposed within the dielectric housing, the dielectric housing fixes the first terminal and the second terminal of the terminal network, thus respectively fixing the first distance and the second distance, and the first contact portion and the second contact portion forms an electric connection interface on any surface of the electrical connector.
