Abstract: An electrical connector assembly (1) includes a base (10), a fixing member (11), and a clip (13). The base defines at least one installation portion (12, 15). The fixing member is pivotally engaged with the installation portion, and comprises an actuator (110) movably engaged in the at least one installation portion. The clip is attached to the base opposite from the at least one installation portion, and comprises a groove (130) defining a first corner (131) and a second corner (132) adapted to cooperate with the actuator. The actuator can slide from the first corner to the second corner when the fixing member engages with the clip, whereby no lateral movement of the clip relative to the base occurs. Thus, a LGA IC module (2) can be fixed on the electrical connector assembly reliably.
