Abstract

An electronic card connector includes an insulating body, a conductive terminal and a switch device, the switch device includes first and second switch terminals, and the second switch terminal is provided with an abutting portion protruding from the upper surface of the insulating body. When the electronic card is inserted, the electronic card first contacts with the conductive terminal, and then the front edge of the electronic card pushes the second switch terminal abutting portion, so that the second and first switch terminals are electrically contacted to generate an instantaneous pulse current to start the electrical circuit. The delayed contact function is achieved, and when the card is withdrawn, the electrical circuit finishes working earlier than the electronic card, so the electronic card can be plugged and pulled out under the working state of the electronic device without affecting its internal electronic circuit.
