Patent ID: 8460021

Claim:
A card insert/eject mechanism of a card connector, applicable to a card connector of an electronic device, the card insert/eject mechanism comprising: an insulating seat formed with a receiving space and a track groove, the insulating seat having an inner bottom surface which corresponds in position to the receiving space and is provided with a plurality of signal terminals, the track groove being adjacent to a lateral side of the receiving space; a metal housing connected to the insulating seat to form a single piece, wherein the metal housing covers a top of the receiving space and a top of the track groove such that the receiving space and the track groove form a card insertion slot and a bar hole at a front end of the insulating seat respectively, the metal housing having a bottom surface provided with a position-limiting resilient plate, the position-limiting resilient plate extending into the track groove; a sliding block provided in and slidable along the track groove, the sliding block having a top surface formed with a position-limiting recess for receiving the position-limiting resilient plate in such a way that an end of the position-limiting resilient plate presses against an inner surface of the position-limiting recess, the sliding block being laterally provided with a pushing portion extending into the receiving space so that, when an electronic card is inserted into the card insertion slot, the pushing portion is pushed by an end of the electronic card and thus moves the sliding block away from the bar hole, causing the end of the position-limiting resilient plate to disengage from the position-limiting recess and press against a front end of the sliding block; a resilient element provided in the track groove and configured for applying a force to a rear end of the sliding block, thereby biasing the sliding block toward the bar hole; and a release bar provided in and slidable along the track groove, the release bar having an end adjacent to the bar hole and an opposite end adjacent to the front end of the sliding block, wherein the release bar, when pushed, applies a force to the position-limiting resilient plate such that the end of the position-limiting resilient plate does not press against the front end of the sliding block.
