Electrical card connector capable of indicating card's false insertion

An electrical card connector for use with an electronic card, comprising:

• an insulative housing defining a card receiving space therein for receiving the electronic card;
• a plurality of contacts retained in the insulative housing with corresponding contacting sections extending into the card receiving space;
• a slider moveably positioned on the insulative housing and beside the card receiving space and moveable along a front-to-back direction essentially between opposite inner/rear locked and outer/front ejected positions, the slider comprising a base portion and an actuating portion sidewardly protruding from the base portion toward the receiving space,
• the slider forming a multi-sector slot structure defining a first loop path for a correct insertion and a second loop path for an incorrect insertion;
• a spring constantly urging the slider forward toward the outer ejected position;
• a pin member having opposite first and second ends, the first end being fixed while the second end moveable along the slot structure;
• and
• both said first loop path and said second loop path sharing a same initial route and a same final route while being divergent from each other with corresponding intermediate routes between said same initial route and said same final route;
• wherein
• the intermediate route of the first loop path forms a locking position to lock the slider in the inner locked position while the intermediate route of the second loop path forms no locking position so that the slider is not locked in the inner locked position but moves back to the outer ejected position.

A method of identifying correct insertion of an electronic card into an electrical card connector, comprising steps of:

• providing the electrical card connector with an insulative housing having a card receiving space with a plurality of contacts therein;
• providing a slider positioned beside the card receiving space and moveable along a front-to-back direction between opposite front ejected and rear locked positions;
• providing a pin member with opposite fixed and moving ends;
• providing a spring to constantly urge the slider forward;
• equipping said slider with a multi-sector slot structure to define a first loop path and a second loop path along which the moving end of the pin member moves selectively;
• and
• actuating the slider to guide the pin member to move either along the first loop path to arrive at the rear locked position in response to correct insertion of the electronic card or along the second loop path to arrive at the front rejected position in response to incorrect insertion of the electronic card.
