Abstract
Abstract A header connector (30) includes an insulative housing (32) having a plurality of contacts (42) extending upwardly therethrough. The housing (32) is generally formed by a first pair of opposite side walls (34) and a second pair of opposite end walls (36) to define a space (40) therein for receiving a module (102) and its associated socket connector (100). A pair of cavities (44) are disposed adjacent to two opposite ends of the housing (32) for respectively receiving a pair of corresponding latch/eject members (70) therein wherein each cavity (70) includes a cross-shaped cross-section and extends through in a lateral direction the corresponding surfaces of the housing which define such cavity (44). Thus, the latch/eject member (70) within the cavity (44) is adapted to be in the housing (32) pivotally retained along an axis which extends in the lengthwise direction of the housing (32) whereby such latch/eject member (70) may lock the module (102) when the latch/eject member (70) is in a first (vertical) locking position, and may project out of the corresponding cavity (44) in the lateral direction for release and ejection of the module (102) when the latch/eject member (70) is in a second (angular) open position.
