An electrical connector assembly comprising:

• a first spacer defining a plurality of first terminal receiving slots and a spacer receiving slot in communicating with a bottom thereof;
• a second spacer received within the spacer receiving slot of the first spacer and defining a plurality of second terminal receiving slots therein;
• a first connector secured to the first spacer and including a first housing and a plurality of first terminals secured to the first housing, the first terminals including first solder tails extending through the first terminal receiving slots of the first spacer;
• and
• a second connector secured to the first spacer and including a second housing disposed beside the first housing and a plurality of second terminals, the second terminals including second solder tails extending through the second terminal receiving slots of the second spacer for being soldered to a motherboard,
• wherein the second terminal receiving slots are defined at two opposite sides of the second spacer, the terminal receiving slots are defined at two opposite sides of the second spacer, the terminal receiving slots at one side being staggered with those at the other side,
• wherein the first spacer defines a first depressed surface thereof, and a second depressed surface lower than the top surface but higher than the first depressed surface, the first connector is arranged on the first depressed surface and the second connector is arranged on the second depressed surface.
