1. A card connector comprising:
- an insulative housing having a groove;
a plurality of terminals affixed in the insulative housing;
a shielding shell attached to the insulative housing to form a cavity;
a movable member insertable in the cavity; and
an EPM (Electro-Permanent Magnet) affixed in the insulative housing, wherein the movable member is attracted by the EPM under a first current in one direction during card-insertion and released by EPM under a second current in an opposite direction during card-ejection.

Abstract
A card connector (100) includes an insulative housing (1), a number of terminals (2) affixed in the insulative housing, a shielding shell (4) attached to the insulative housing to form a cavity (11), a tray (3) insertable in the cavity; and an EPM (5) affixed in the insulative housing. The tray is attracted by the EPM under a first current in one direction during tray-insertion and released by the EPM under a second current in opposite direction during tray-ejection.

11. An electrical connector comprising:
-
an insulative housing forming a receiving cavity communicating with an exterior along a front-to-back direction via a front opening; a plurality of terminals disposed in the housing with contacting sections extending into the receiving cavity; a metallic shell secured with the housing and covering the receiving cavity in a vertical direction perpendicular to said front-to-back direction; a tray removably receiving within the receiving cavity and equipped with at least a portion made from metal; a magnetic device activated by electricity and located at a rear end of the housing opposite to the front opening in said front-to-back direction and cooperating with the tray via magnetic forces to have said tray remain in the receiving cavity. - View Dependent Claims (12, 13, 14, 15)

16. A method of loading/unloading an electronic card with regard to an electrical connector, comprising steps of:
-
providing an electrical card connector with an insulative housing forming a receiving cavity communicating with an exterior along a front-to-back direction via a front opening, providing a plurality of terminals in the housing with contacting sections extending into the receiving cavity; providing a metallic shell upon the housing for covering said receiving cavity in a vertical direction perpendicular to said front-to-back direction; providing a tray with a metallic portion; and providing a magnetic device, which is activated by electricity, around a rear end of the housing opposite to the front opening in the front-to-back direction;
whereinduring loading, the tray is inserted into the receiving cavity from the front opening to activate the magnetic device to generate a magnetic force to have the tray remain in the receiving cavity;
during unloading, the magnetic device is activated to be demagnetized to remove the magnetic force. - View Dependent Claims (17, 18, 19, 20)
