ABSTRACT:
A PGA socket having structure that permits the slide plate to be kept center-aligned while moving on the base housing, thus assuring that reliable electric connections be established between the PGA lead pins and the terminals of the socket. The PGA socket includes a base housing and a slide plate, the slide plate being movable between a first, or lead pin inserting position, in which the lead pins of the pin grid array package can be inserted in the through holes and the terminal mounts and a second, or locking position, in which the lead pins are applied to the terminals in the terminal mounts. The PGA socket includes at least one resilient piece on either the base housing or the slide plate and that other of the base housing or slide plate has an engagement means for receiving the at least one resilient piece. The resilient piece may be engaged with the engagement means in such a manner that the slide plate is kept aligned relative to its center when it is operated between the first position and the second position. Moreover, the PGA socket may include two resilient pieces, and the two resilient pieces may be arranged symmetrically with respect to the centerline of the base housing.
