A socket connector includes a housing extending along a longitudinal axis between opposed ends. The housing includes a mounting face configured to be received on the circuit board and a slot configured to receive the mating edge of the card edge module. A latch member is pivotably connected to the housing. The latch member is movable between an open position and a closed position. A biasing member is connected between the housing and the latch member. The biasing member biases the latch member toward the closed position.
