The present invention further defines: described the first insulating body comprises upper end face and the upper bottom surface being oppositely arranged and runs through end face and the accepting groove of upper bottom surface, described accepting groove comprises the first groove and the second groove that are interconnected, described the first groove is provided with the slit for fixing conducting terminal, and described the second groove and this slit are interval and are oppositely arranged.
The present invention further defines: described shielding sheet comprise body, from body upwards bend the elastic arm of extension and from body one lateral buckling extend supporter, described holding part from body to downward-extension.
The present invention further defines: described conducting terminal comprises that main part, autonomous body upwards bend the contact site of extension, independently body bends the holding parts of the weld part of extension and a lateral buckling extension of autonomous body downwards.
The present invention further defines: the weld part of described conducting terminal passes the through hole of ground plate and do not contact with through hole.
The present invention further defines: described the second insulating body comprises lower end face and the bottom surface being oppositely arranged and the holding tank that runs through lower end face and bottom surface, and described lower end face upwards protrudes out and is provided with some boss that coordinate with through hole.
Compared to prior art, at least there is following advantage in electric connector of the present invention: electric connector is provided with ground plate between the first insulating body and the second insulating body, and this ground plate electrically conducts with shielding sheet, this ground plate is linked to be shielding sheet an entirety and conducting terminal is shielded, and the arranging of this ground plate can reach preferably shield effectiveness and can save cost.
