Abstract
Abstract A connection system for coupling a memory card or other device to a computer system. The connection system utilizes a sliding rack of contacts to provide electrical coupling between the card and the connections system. This sliding rack of contacts is pushed back as a card is inserted and allows the card to be inserted wiht minimal force. The card may then be released by applying a small amount of pressure and then releasing the card. A spring device in the connection system will then force the card out of the connection system to a position where it may be easily removed. The preferred embodiment of the present invention produces an audible and tactile click when the card is properly inserted into the connection system housing. Another audible and tactile click is produced when the card is released. The preferred embodiment also utilizes a flexible circuit for coupling a contact assembly on the sliding rack of connectors to the computer system or other device.
