Electrical connector

An electrical connector, comprising:

• an insulating body, having a plurality of accommodating slots running therethrough along a vertical direction, wherein a side surface of each of the accommodating slots is provided with a stopping block;
• and
• a plurality of terminals and a plurality of solder balls, correspondingly accommodated in the accommodating slots respectively, wherein each of the terminals has a flat plate portion located in a corresponding accommodating slot of the accommodating slots and two first soldering portions extending downward from the flat plate portion and abreast, a receiving slot is formed between the two first soldering portions, the flat plate portion and the two first soldering portions are coplanar, two second soldering portions extend toward each other from lower ends of the two first soldering portions, each of end portions of the two second soldering portion facing each other respectively bends toward a direction away from a corresponding solder ball of the solder balls to form a bending section, the bending section is located below the receiving slot and is connected to the receiving slot, a plate surface of the bending section facing the corresponding solder ball is defined as a matching surface, along the direction away from the corresponding solder ball, a gap between the two matching surfaces of the two bending sections of the two second soldering portions of each of the terminals becomes smaller, the corresponding solder ball is partially accommodated between the receiving slot and the two matching surfaces of the two bending sections of the two second soldering portions, the matching surface abuts against the corresponding solder ball and is located below a horizontal central plane of the corresponding solder ball, and the stopping block of the corresponding accommodating slot is located above the bending section to stop the bending section from moving upward.
