Patent ID: 7771227

Claim:
A circuit board connector assembly adapted for connecting two printed circuit boards, comprising: two plug connectors each connected with the corresponding printed circuit boards and including a plug insulating housing having a plug base body, two opposite ends of the plug base body respectively defining a holding cavity extending longitudinally and passing through a side surface thereof, the holding cavity being connected with the side surface by a slope, and a plurality of plug terminals disposed in the plug insulating housing for being soldered to the corresponding printed circuit board; and a receptacle connector mated with and electrically connecting the two plug connectors, the receptacle connector including a receptacle insulating housing having a receptacle base body, each of two opposite ends of the receptacle base body extending downward to form two connecting arms spaced away from each other, a free end of each of the connecting arms being bent inward to form a buckling portion extending longitudinally, and a plurality of receptacle terminals disposed in the receptacle insulating housing and each electrically connecting the corresponding two plug terminals of the two plug connectors so as to form an electrical connection between the printed circuit boards, wherein the buckling portions can be buckled into and slide out from the corresponding holding cavities along the corresponding slopes.
