Abstract
The invention discloses an electric connector shielding structure. The electric connector comprises a contact element, wherein the contact element comprises a signal contact element and an earthing contact element; multiple extension parts are arranged on the earthing contact element; a plastic matrix is arranged outside the contact element; an electroplated layer is arranged on the external surface of the plastic matrix; openings matched with the extension parts arranged on the earthing contact element are arranged on the plastic matrix; the extension direction of the extension parts arranged on the earthing contact element is the thickness direction of the earthing contact element; the electroplated layer is electrically connected with the extension parts arranged on the earthing contact element; and the extension parts arranged on the earthing contact element extend out of the external surface of the plastic matrix. The electric connector shielding structure is produced by injection molding and electroplating processes. By adopting the electric connector shielding structure, the multipoint connection between the earthing contact element and the electroplated layer of the electric connector is realized, thus the shielding is sufficient, and the crosstalk among signal wires in the electric connector is low; and the plastic matrix is not limited by the material, thus the cost and connector weight are greatly reduced.
