The present invention relates to an electrical connection port, an electric connection port is in bar, the insulating housing having an insulating housing and a plurality of terminals and the metal body is provided with an engaging portion and the main body is formed in the cover to shield the coupling section, further electrical connection ports are one end of provided with a pair of grounding tabs secured to both sides of the coupling portion, and the grounding tabs are connected with the main body and the other end of the electrical grounding tabs extend below the upper surface portion bonded. When combined connection ports would be inserted into the electrical connection on site, a ground tab is connected to the main body and the electric coupling connection ports, terminals of electrical connection ports are the static electricity is better electrical performance be discharged accumulates after I Physical fit to ground and bond the connection port, that achievement do.
