The utility model provides an electrical connector which is installed on a circuit board with a signal conductive gasket and a grounding conductive gasket. The grounding conductive gasket is longer than the signal conductive gasket. The electric connector comprises an insulating body and a first group of terminals. The insulating body comprises a slot. The first group of terminals comprises two pairs of differential signal terminals and a plurality of grounding terminals. Each pair of differential signal terminals is positioned between two corresponding signal terminals. Each terminal of the first group of terminals comprises a fixed part, a contact part, an extension part, a welding part and an elastic bending part. The fixed part is fixed on the insulating body. The contact part is extended from the fixed part to the slot. The extension part is extended out of the insulating body from the fixed part. The welding part is positioned at the corresponding signal conductive gasket or grounding conductive gasket. The elastic bending part is positioned between the extension part and the welding part. According to the electric connector, a crosstalk phenomenon between the two differential signals and electromagnetic wave interference generated in the transmission of the differential signals can be effectively reduced, side edges of welding parts of the signal terminals can be coated by solder, and a holding force can be enhanced.
