Card edge connector

An electrical connector, comprising:

• an insulative housing having a mounting surface and a mating surface on opposite sides in a mating direction and at least one mounting chamber, the mounting chamber extending and penetrating the mounting surface in the mating direction, and the mounting chamber having a top accommodating portion and a bottom accommodating portion extending and penetrating the mounting surface from the top accommodating portion in the mating direction, the insulative housing further having two side walls facing each other in a width direction perpendicular to the mating direction, and each corresponding side wall being formed with a top limiting surface and a bottom limiting surface which define the top accommodating portion, the top limiting surface facing the mounting surface, the bottom limiting surface facing the top limiting surface in the mating direction and being closer to the bottom accommodating portion than the top limiting surface;
• a plurality of conductive terminals provided to the insulative housing;
• and
• at least one board fastener provided to the insulative housing and corresponding to the at least one mounting chamber, the board fastener being plate-shaped and having a mounting section accommodated in the top accommodating portion, an intermediate section extending from the mounting section and accommodated in the bottom accommodating portion and a tail section extending out of the mounting surface of the insulative housing from the intermediate section, the mounting section having a body portion connecting the intermediate section, two abutting shoulders respectively abutting against the two bottom limiting surfaces and two latching elastic arms extending from both sides of the body portion and having ends thereof respectively to abut against the two top limiting surfaces, so that the mounting section being limited in position by the two bottom limiting surfaces and the two top limiting surfaces in the mating direction.
