Abstract: A securing mechanism for retaining a daughter board upon the primary board includes a base, which is moveably assembled upon the main board, and a latch assembled upon the base and moveable between a locking position and an unlocking position. The base forms a support platform upwardly abutting against the underside of the daughter board and equipped with an arc protrusion for receipt within a notch of the daughter board, and a grounding piece with one end mechanically and electrically connecting a grounding pad of the daughter board and the other end mechanically and electrically connecting a grounding pad on the main board. The base forms a horizontal slot to receive the main body so as to retain the base to the main body in position in the vertical direction. The latch forms a pressing face downwardly pressing an upper side of the daughter board.

The retaining part includes a grounding member and an insulating base inserting molded with the grounding member, the insulating base are retained with the insulating housing and located between the two rows of the terminals, the grounding member includes two rows of grounding fingers extending out the insulating base and contacting with the grounding terminals one by one.

Abstract: A card edge connector includes an insulative elongated housing defining an elongated slot extending along a longitudinal direction. Two rows of contacts are disposed in the housing so as to be paired in each cross-sectional plane in a transverse direction. A pair of towers are located at two opposite ends of the housing in the longitudinal direction. A pair of ejectors/lockers are disposed in the corresponding towers and rotational about a pivot extending along the transverse direction. Each ejector has a bottom kicker adapted to intimately confront a bottom edge of the memory module for ejecting the memory module out of the housing. The kicker slightly interferes with the contacting sections of the neighboring contacts when the ejector is located at an outer position so as to be retained in position with regard to the housing.

Abstract: A card edge connector includes an insulative elongated housing, a plurality of contacts disposed in the housing, and a pair of rotatable ejectors at two ends of the housing. The housing includes a pair of side walls extending along the longitudinal direction with a receiving slot therebetween in a transverse direction perpendicular to the longitudinal direction, and a pair of towers at two opposite ends of the housing in the longitudinal direction. The receiving slot is configured to receive a card type memory module. The pair of ejectors are disposed in the corresponding towers, respectively. Each ejector includes a kicker at the bottom wherein a tip of the kicker will not invade into the space between the pair of outermost contacts so as not interfere with the corresponding outermost contacts when the ejector is rotated to be at an open/ejecting position.

The housing includes a pair of side walls extending along the longitudinal direction with a receiving slot therebetween in a transverse direction perpendicular to the longitudinal direction. The receiving slot is configured to receive a card type memory module. Each contact is equipped with the solder ball for surface mounting upon the printed circuit board. The contact includes a retaining section secured to the housing, a deflectable contacting section extending upwardly from the retaining section, and a tail section extending downwardly from the retaining section and including a connecting section and a solder pad. The solder pads of the contacts in a same row along the longitudinal direction are alternately arranged in opposite directions in the transverse direction perpendicular to the longitudinal direction.
