Claim:
A card edge connector assembly for connecting a pair of electrical cards to a printed circuit board comprising: a first connector and a second connector; said first connector including a first insulative housing defining a first elongated receiving slot which defines a longitudinal direction and is equipped with a plurality of first contacts by two sides thereof, each first contact having a solder tail protruding out of a first mounting face defined by the first connector; said second connector including a second insulative housing defining a second elongated slot with a plurality of second contacts by two sides thereof, each second contact having a solder tail protruding out of a second mounting face defined by the second connector; a connecting device, interconnecting the first and second connectors together; wherein the second mounting face of the second connector is moveable relative to the first mounting face of the first connector; wherein the first and the second contacts of the first and second connectors only allow said electrical cards to be inserted into the corresponding elongated slot in a horizontal manner; wherein said connecting device has a pair of positioning portions disposed at longitudinal ends of the first and second insulative housings for interconnecting the first and second insulative housings together; and wherein sliding grooves are defined on the first and second insulative housings for receiving said positioning portions, while the dimension of the sliding grooves is larger than that of the positioning portions so as to allow the second insulative housing to move relative to the first insulative housing.
