Electrical connector with board locks

An electrical connector assembly comprising:

• a circuit board defining a pair of through holes therein;
• and
• an electrical connector mounted on the circuit board and comprising:
• an insulative housing having a mounting face;
• a plurality of terminals retained in the insulative housing for electrical connection with the circuit board;
• and
• a pair of board locks including a connecting portion downwardly extending from the mounting face of the housing, a hook formed at a free end of the connecting portion for engaging with a bottom face of the circuit board and having a free end extending in a direction toward the mating face of the housing, and a rib projecting from the connecting portion in a direction opposite to the extending direction of a free end of the hook for abutting against an inner wall of a corresponding through hole of the circuit board;
• wherein a horizontal distance between a free end of the hook and an outer side of the rib is larger than a horizontal dimension of the through hole of the circuit board;
• wherein the board lock is generally of a J-shaped configuration and the connecting portion is of a cylindrical shape;
• wherein the rib extends along the connecting portion for a predetermined distance;
• wherein the housing comprises a mating face perpendicular to the mounting face, and the free end of the hook of the board lock perpendicularly extends from the connecting portion in a direction toward the mating face of the housing;
• wherein a horizontal distance between the free end of the hook and an outer side of the connecting portion is not larger than the horizontal dimension of the through hole of the circuit board.
