The metal conductive male socket 3 includes a conductive shell body 31 and a plug-in post 32. The plug column 32 is formed by extending the left side wall of the conductive shell body 31 to the left, and is provided with a receiving cavity 321 therein for placing the insulating column 2. The metal conductive male socket 3 is inserted and butted with the insulating plastic female socket 4 along the left and right direction by means of the upper inserting column 32. It should be emphasized that, the high-speed data connector with shielding function is additionally provided with a metal shielding member 6, which is clamped and fixed on the periphery of the metal conductive male socket 3, and the right end face of the insulating plastic female socket 4 is pressed against and pressed tightly, so that the influence of external electromagnetic interference on the signal transmission process is effectively reduced, the reliability and stability of signal transmission are ensured, and the high-speed data connector has excellent high-frequency performance.

As a further refinement of the structure of the high-speed data connector having the shielding function, the metal shield 6 is mainly composed of a shield body 61, a claw 62, an electromagnetic shield strip 63, and the like (as shown in fig. 7). Wherein, the shielding body 61 is wrapped around the outer sidewall of the metal conductive male socket 3.
