Stacked card edge connector assembly having ejector for removing inserted cards simultaneously

A card edge connector assembly comprising:

• a first connector, comprising a first insulative housing defining a first central slot expanding along a transverse direction and a recess defined under the first insulative housing, a plurality of first terminals being arranged at opposite sides of the first central slot;
• a second lower connector, comprising a second insulative housing received in said recess, the second insulative housing defining a second central slot expanding along the transverse direction and a pair of passageways extending along a rear-to-front direction and in communication with the second central slot, a plurality of second terminals being arranged at opposite sides of the second central slot;
• an ejecting device comprising a first ejecting portion and a second ejecting portion;
• wherein the first ejecting portion is firstly projecting into the first central slot and then the second ejecting portion is projecting into the second central slot through the corresponding passageway;
• wherein the first and second ejecting portions are located around a same plane and the first ejecting portion is located in front of the second ejecting portion.

A card edge connector assembly comprising:

• a lower connector including a lower insulative housing defining a lower horizontal slot for receiving a lower card;
• a plurality of lower contacts disposed in the lower housing for engagement with the lower card;
• an upper connector including an upper insulative housing defining an upper horizontal slot for receiving an upper card;
• a plurality of upper contacts disposed in the upper insulative housing for engagement with the upper card;
• an ejecting device sandwiched between the upper housing and the lower housing, and further back and forth moveable relative to the upper and lower housings in a front-to-back direction;
• wherein one of said upper and lower housings defines a groove structure to allow the ejecting device to be assembled to said one of said upper housing and said lower housing;
• said ejecting device including one ejecting portion extending into one of said upper horizontal slot and said lower horizontal slot for ejecting the corresponding card therein;
• wherein said ejecting device further defines an other ejecting portion extending into the other of said upper horizontal slot and said lower horizontal slot;
• wherein said ejecting portion and said another ejection portion are offset from each other in said front-to-back direction for ejecting the corresponding cards at different time;
• wherein the other of said upper housing and said lower housing includes a wall to prevent withdrawal of the ejecting device from said one of the upper housing and the lower housing.
