Electrical connector with board lock devices

An electrical connector comprising:

• an insulative housing defining a mounting face for mounting to a printed circuit board;
• a plurality of terminals disposed in the housing;
• and
• a board lock including a retention section, and a horizontal arm from which a pair of mounting legs downwardly extend beyond the mounting face and spaced from each other for commonly mounting to a through hole in said printed circuit board;
• wherein
• at least one of said pair of mounting legs defines a lying Z-shaped configuration under a condition that a distance between lower end regions of said pair of mounting legs is much larger than that between upper end regions of said pair of mounting legs;
• wherein said retention section and said horizontal arm are spaced from each other and linked by a bight to commonly form a lying U-shaped configuration;
• and
• wherein the lying Z-shaped configuration is closer to the bight than the other of the pair of mounting legs and includes an upper vertical section, a lower vertical section and a horizontal section therebetween, and said lower vertical section is located outward relative to the upper vertical section in the corresponding through hole.
