Electrical card connector for receiving at least two electrical cards

An electrical stack card connector comprising:

• a first connector for mating with an express card;
• a second connector located at a rear of the first connector and for mating with a smart card;
• a shell covering on the first connector;
• an ejector mounted on a lateral side of the shell;
• a bottom plate assembled on a bottom of the shell and located on a top of the second connector;
• the bottom plate is attached to the shell and located at a top of the second connector, which comprises a main plate, a front wall extending downwardly from a front of the main plate, a pair of vertical portions extending downwardly from opposite sides of the main plate and a bending portion extending inwardly from each of the vertical portions;
• lateral sides of the main plate form a plurality of hooks, which mate with holes of the shell for holding the bottom plate on the bottom of the shell;
• the main plate, the vertical portion and the bending portion define a guiding slot for guiding the smart card;
• a first receiving room has a same width with a second receiving room and the first receiving room is higher than the second receiving room;
• wherein the second connector comprises a switch contact, aligned with the front wall of the bottom plate in a vertical direction;
• wherein the first connector and the second connector are mounted on a same side of a PCB, the bottom plate comprises the front wall and a pair of guiding slots, the guiding slots extend in a card insertion direction for guiding the card, and the front wall is located at the front of the main plate for stopping the card excessively.

An electrical eject card connector assembly comprising:

• the switch contacts;
• first and second connectors stacked with each other;
• the first connector defining an L-shaped receiving cavity, in a top view, with a front large space and a rear small space thereof;
• a plurality of first contacts disposed in the rear small space;
• the second connector defining a rectangular receiving cavity configured and dimensioned similar to said front large space;
• and
• a plurality of second contacts disposed in a rectangular space;
• wherein the L-shaped receiving cavity is thicker than the rectangular receiving cavity;
• a L-shaped receiving cavity is defined by a first metallic shell, the rectangular receiving cavity is defined by a second metallic shell, and a pair of standoffs retainably engaging said first metallic shell and said second metallic shell;
• a second metallic shell which defines at least a stopper at a front edge thereof to avoid excessive forward movement of an electronic card which is inserted into the rectangular receiving cavity;
• said second shell is assembled on a bottom of the first shell and located on a top of the second connector;
• a second shell comprise a main plate, a front wall extending downwardly from a front of the main plate, a pair of vertical portions extending inwardly from the vertical portion;
• lateral sides of the main plate form a plurality of hooks, a guiding slot for guiding the smart card.
