Patent ID: 8597051

Claim:
A receptacle connector adapted for soldering with a circuit board and engaging with a plug connector, comprising: an insulating housing having a base wall, a top wall, two side walls and a bottom wall which are interconnected with one another to form an accommodating chamber thereamong for inserting the plug connector therein, a front of the base wall protruding forward to form a tongue portion projecting in the accommodating chamber, the insulating housing defining a plurality of terminal grooves of which each extends longitudinally along a top of the tongue portion and further penetrates through the base wall, the top wall defining at least two locating grooves with middles thereof vertically penetrating through the top wall to communicate with the accommodating chamber, the bottom wall defining at least two circular holes communicating with the accommodating chamber; a plurality of terminals molded in the terminal grooves of the insulating housing with front ends thereof exposed in the top of the tongue portion to electrically contact with the plug connector, and rear ends thereof projecting out of the insulating housing through the base wall to be soldered on the circuit board; at least two first connecting elements located in the locating grooves with middles thereof projecting into the accommodating chamber through the middles of the locating grooves, two opposite sides of each first connecting element protruding upward to form two first fastening portions; a second connecting element having a base plate mounted to a bottom of the bottom wall, a front side of the base plate defining at least two mouths, one inner end of each mouth inclining upward and extending towards the other inner end of the mouth to form a cantilever arm, a free end of the cantilever arm spreading outward and protruding upward to form a touching portion projecting into the accommodating chamber through the circular hole, at least two second fastening portions being punched downward from a top of the base plate and located between the two mouths; a first waterproof board mounted to a top of the top wall of the insulating housing, and defining a plurality of first fastening holes for receiving the first fastening portions therein; a second waterproof board mounted under the second connecting element, and defining at least two second fastening holes for receiving the second fastening portions therein, wherein a top face of the first waterproof board and a bottom face of the second waterproof board are coated with waterproof adhesive material to form a waterproof adhesive layer respectively; and a shielding shell surrounding the insulating housing together with the first waterproof board and the second waterproof board.
