Card connector

An electrical card connector ejector for receiving Smart Card and an Express Card comprising:

• first and second ports stacked with each other each defining a card receiving cavity;
• a plurality of first contacts extending into the card receiving cavity of the first port;
• a plurality of second contacts extending into the card receiving cavity of the second port;
• an area occupied by the first contacts and located around a rear portion of said first port, said area being much smaller than remainders of said first port;
• and
• a main plate belonging to the first port and located on opposite side of the card receiving cavity with regard to the area,
• a plurality of insulating body being covered by a plurality of shells to define the plurality of receiving cavities, and having the main plate comprising a platform, the platform defining an inclined front section for easing insertion of the card;
• the terminal modules assembled with the shells;
• and
• a plurality of terminals and one of the terminals are arranged in a transverse direction perpendicular to an insertion direction of the card;
• the insulating housing comprises a base section, a fixing portion integrally extending from one end of the base section to form a L-shaped body and a guiding portion extending from the fixing portion opposite to a card insertion direction;
• the base section has an engaging plate protruding into one of the receiving cavity, and
• on the fixing portion, a pair of grooves is placed in the same direction of one of the terminals arranged to receive ejecting mechanisms;
• the ejecting mechanisms, respectively, comprises an ejecting device protruding into the receiving space, a spring device for moving the ejecting device in the card ejecting direction, a cam follower capable of overcoming the spring device and a cam groove allowing one end of the cam follower to slide therein;
• wherein the platform is formed on opposite side of the terminal module for pressing on an inserted card;
• said main plate forming a raised platform thereon corresponding to the area so as to form a narrower space therebetween in a vertical direction, in comparison with other portions in the card receiving cavity, for efficiently holding an electronic card therebetween and easing manufacturing the connector and assembling the card.

• a plurality of first contacts extending into the card receiving cavity of the first port;
• a plurality of second contacts extending into the card receiving cavity of the second port;
• an insulative housing located between said first port and said second port and defining a main body to receive the second contacts and a large truncated triangular guiding portion in front of the main body;
• and a metallic shield located between said first port and said second port and defining a small raised triangular section to cooperate with said large truncated triangular portion to form a complete large triangular device for guiding insertion of an electronic card into the card receiving cavity of the second port;
• wherein said large truncated triangular portion is thicker than the small raised triangular section;
• the insulating housing comprises a base section, a fixing portion integrally extending from one end of the base section and a guiding portion extending from the fixing portion opposite to the card insertion direction;
• the base section has an engaging plate protruding into a second receiving cavity, and
• on the fixing portion, a pair of grooves is placed in the same direction of the second terminals arranged to receive two ejecting mechanisms;
• the ejecting mechanisms, respectively, comprises an ejecting device protruding into the ports, a spring device for moving the ejecting device in the card ejecting direction, a cam follower capable of overcoming the spring device and a cam groove allowing one end of the cam follower to slide therein to place the ejecting device in a desirable position;
• wherein a platform is formed on opposite side of the terminal module for pressing on inserted card, and the platform defining an index portion to lead the card into the first port fully.
