A dual socket connector has an insulative housing assembly, multiple first terminals, multiple second terminals, multiple third terminals and a shell. The insulative housing assembly has a top tongue, a bottom tongue and a partition formed between the top and bottom tongues. The first terminals are mounted on one of the top and bottom tongues for USB 2.0 signal transmission. The second and third terminals are mounted on the other tongue for USB 3.0 signal transmission. The shell covers the insulative housing assembly and defines upper and lower socket holes with the partition for engaging different plug connectors. The dual socket connector is compact and has high compatibility.
