Abstract

The invention provides a contact module and an electric connector. The electric connector comprises the contact module, wherein the contact module comprises an insulator and differential pairs; the differential pairs are arranged in the insulator on the left and right in parallel; ground contacts are respectively arranged at the left side and the right side of each differential pair in the insulator; shielding plates are arranged at the upper side and / or the lower side of the insulator; abdicating channels which extend towards the outer side of the insulator from the ground contacts are respectively formed in the positions, corresponding to the ground contacts, of the insulator; the abdicating channels extend up and down; and an elastic claw which is used for extending into each abdicating channel and is in jacked coordination with each ground contact in the insulator is arranged on each shielding plate. The electric connector provided by the invention electrically contacts the ground contacts through the elastic claws on the shielding plates, so that the electric contact stability and reliability of the shielding plates and the ground contacts are ensured; and the shielding plates are simple in structure and relatively low in manufacturing cost.

Description

technical field [0001] The invention relates to a contact module and an electrical connector. Background technique [0002] Electrical connectors are components that realize conductive interconnection, and are widely used in the field of electronic communications.
