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.
Claims20
A card connector comprising:
- an insulative housing;
- 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.
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.
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 to 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;
- wherein
- during 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.
