Abstract:
An electrical connector adapted for connecting a memory module to a circuit board, comprising:an elongate housing including:an elongate body including a plurality of cavities formed in opposite side walls thereof and an elongate slot defined between the two side walls in communication with the cavities for insertion of the memory module, the slot being slightly wider than the memory module; anda pair of arms extending from opposite ends of the body, each arm defining a channel in an inner surface thereof in communication with the slot of the body for guiding the memory module into the slot, a pair of elongate ribs projecting from opposite inner surfaces of opposite side walls of each arm for abutting against the memory module thereby restricting movement of the memory module along a lateral direction;a plurality of contacts received in the cavities of the housing and exposed to the slot for mating with the memory module; andan ejector secured to the housing for ejecting the memory module from the slot of the housing;wherein each rib projects from a lower portion of the inner surface of the side wall of the arm proximate the slot of the body to an upper portion of the arm;wherein a chamfer is formed in a top portion of each rib for guiding the memory module to abut against the rib;wherein the surface of each rib is arcuate for making a line contact with the memory module thereby reducing a frictional force between the ribs and the memory module.
