A waterproof connector for mounting to a circuit board includes an insulative housing, a number of contacts fixed in the insulative housing, a metallic shell enclosing the insulative housing and a soldering plate fixed to a peripheral wall of the metallic shell. The insulative housing includes a tongue portion residing in a receiving space which is jointly formed by the insulative housing and the metallic shell. The peripheral wall defines a pair of latch holes in communication with the receiving space for locking with an inserted plug connector. The soldering plate is fixed to the peripheral wall so as to seal the pair of latch holes. The soldering plate is located between the peripheral wall and the circuit board. The soldering plate includes at least one emboss for surface mounting onto the circuit board.
