Electrical connector

An electrical connector, comprising:

• an insulating housing having a fixing slot, two first receiving grooves and two second receiving grooves, the first receiving grooves and the second receiving grooves being spaced apart in a first horizontal direction;
• two first terminals respectively received in the first receiving grooves, the two first terminals being adjacent to each other to form a differential terminal pair for transmitting differential pair signals;
• two second terminals respectively received in the second receiving grooves for grounding, the two second terminals being positioned respectively on opposite sides of the differential terminal pair;
• a shielding member arranged on the insulating housing, the shielding member contacting the two second terminals and being positioned on one side of the differential terminal pair in a second horizontal direction, the first horizontal direction and the second horizontal direction being perpendicular to each other;
• and
• a connecting base assembled in the fixing slot of the insulating housing;
• wherein
• the two first terminals are fixed to the connecting base.
