  • Patent number: 7699637
    Abstract: An LGA connector includes an insulative housing accommodating a plurality of terminals, a stiffener disposed around the insulative housing and a cover attached to the stiffener. The stiffener includes a front end, an opposite rear end, and two substantially vertical sidewalls connecting the front and rear ends. The cover is pivotally mounted to the rear end of the stiffener. The cover includes a pair of lateral sides having blocking walls being bent downwardly and distant to the sidewalls of the stiffener. One of the sidewall of the stiffener and the blocking wall of the cover has a self-aligning portion extending towards the other for leading the blocking wall to prevent the cover from inclining when the cover is rotated from an open position to a close position. Thus, the cover is shielded on the insulative housing safely without interfering with the insulative housing.
