ABSTRACT:
There are provided for an improved card connector contacting structure featuring its compactness and simplicity in construction, higher reliability of contacting action and higher impact resistance. The contacting structure is designed as a card connector comprising a plurality of contact terminals which are arranged in parallel with one another; among the plurality of contact terminals, at least two are the terminals for connecting with the power source; at least two are the terminals for grounding; at least one is for detecting whether the IC card has been loaded securely into the card connector; among the plurality of contact terminals, one of the terminals for grounding comes into contact first with the corresponding external contact of the IC card, among the plurality of contact terminals, the terminal for detecting the card coming into contact last with the corresponding external contact of the IC card.
