Abstract: A receptacle structure, which is specifically referred to a joint assembly of terminal with plural signal pins, a main isolator and a metallic casing, wherein the terminal with plural pins is further separated with an upper row terminator and a lower row terminator, the metallic casing is extended with a fixing part at the back side and is configured with an upper rib and at least a spring on the top surface of fixing part, and both laterals are formed as side curvatures with each side opening. Thus, the present invention provides a better shielding protection against ESD—Electrostatic Discharge and enables a high frequency characteristic control which stabilizes the impedance variation within the error range.
