Card edge connector having improved ejector

A card edge connector comprising:

• a longitudinal insulative housing having a central slot extending along a longitudinal direction for insertion of a memory module, and at least one tower portion extending upwardly from one longitudinal end thereof, the tower portion defining a receiving slot and a pair of circular holes located at two sides of the receiving slot in the transverse direction perpendicular to the longitudinal direction;
• a plurality of contacts retained in the insulative housing and protruding into the central slot for mating with the memory module;
• and
• an ejector having a main portion received in the receiving slot and defining a pair of spindles rotatably received in the corresponding circular holes, an ejecting portion extending from a lower end of the main portion for ejecting the memory module out of the central slot, a “H” shaped locking portion extending inwardly from an upper end of the main portion for latching the memory module into the central slot, and a lever portion extending outwardly from the upper end of the main portion for being handled by a hand or others;
• wherein
• the locking portion comprises a pair of vertical portions extending in a height direction perpendicular to both the longitudinal direction and the transverse direction, and a transverse portion extending in the transverse direction and connecting between the vertical portions to form upper and lower grooves, when the memory module is inserted into the central slot, the transverse portion latches into a cutout formed on a side edge of the memory module to retain the memory module in the height direction, the upper and lower grooves receive upper and lower sides of the side edge separated by the cutout to retain the memory module in the transverse direction.

A card edge connector for use with a card edge module, comprising:

• an elongated insulative housing defining a central slot extending along a longitudinal direction;
• a plurality of contacts disposed in the housing by two sides of the central slot;
• a pair of towers located at two opposite longitudinal ends of the housing in said longitudinal direction, each of said towers defining an inner U-shaped recess for receiving a side region of the card edge module, and an outer receiving slot to receive a corresponding ejector, said ejector being pivotally mounted into the outer receiving slot about a pivot extending in a transverse direction perpendicular to said lengthwise direction, each of said ejector further including an lower kicker located below the inner U-shaped recess in a vertical direction perpendicular to both said longitudinal direction and said transverse direction for upwardly ejecting a bottom edge of the card edge module, and an upper locker located above the inner U-shaped recess in said vertical direction for receipt with a notch formed in said side region of the card edge module;
• wherein
• said locker includes a transverse portion for reception within the notch of the side region of the card edge module, and at least a pair of protrusions formed around the transverse portion to define a groove for intimately sandwiching the side region of the card edge module in the transverse direction above said inner U-shaped recess in the vertical direction.
