A quick ejecting card connector has an insulative housing, an auto ejecting assembly and a tray. The insulative housing has a cavity, a front opening and multiple terminals. The auto ejecting assembly is mounted on the insulative housing and has a locking lever, a resilient locking element and a resilient card ejecting element. The locking lever is mounted pivotally on the insulative housing and has a locking hook. The tray is mounted slidably in the cavity and has a locking hole selectively engaged with the locking hook of the locking lever to lock the completely inserted tray. When the locking hook of the lock lever is disengaged from the locking hole of the tray, the resilient card ejecting element ejects the tray and an electrical card thereon out of the front opening. The insertion and ejection of the tray and the electrical card are implemented without any assistant tools.
