Abstract
A socket electric connector capable of restraining crosstalk comprises several insulated plate bodies, several terminal groups, several shielding sheet groups and a shell. Each terminal group comprises several signal terminals and several grounding terminals. Each signal or grounding terminal comprises a fixed segment, an assembling segment and a contact segment. The fixed segment is embedded in the corresponding insulated plate body. The assembling segment is downwardly extended out of the insulated plate bodies from the fixed segment. The contact segment is forwardly extended out of the insulated plate bodies from the fixed segment. Each shielding sheet group is arranged on one side surface of each insulated plate body. Each shielding sheet group comprises several shielding sheets. The shielding sheets are arranged with intervals and are connected with the corresponding grounding terminals. Each shielding sheet comprises a plate body segment and a protrusion segment. The plate body segment forms at least one bending section along a length and shields a side surface of an assembling segment of the corresponding signal terminal. The protrusion segment is forwardly extended out of the insulated plate bodies from the plate body segment and shields a side surface of a contact segment of the corresponding signal terminal. Through the shielding sheet groups, crosstalk among the signal terminals can be effectively restrained; signal transmission efficiency and a stabilization degree are increased.
