Abstract

A receptacle connector adapted for engaging with a plug connector includes an inner insulating housing, a plurality of terminals integrally molded to the inner insulating housing, a shielding shell, a waterproof plate and an outer insulating housing. The shielding shell is looped from a first metal plate with an inserting space being formed therein. The inner insulating housing together with the terminals is inserted into the inserting space. The shielding shell defines two buckling holes. The waterproof plate is made of a second metal plate thinner than the first metal plate in thickness, and is fastened on the shielding shell. Two opposite sides of the waterproof plate are punched upward to form two receiving hats corresponding to the two buckling holes. The outer insulating housing is integrally molded around the shielding shell, the waterproof plate and the inner insulating housing with soldering portions of the terminals projected outside.

Claims

1. A receptacle connector adapted for engaging with a plug connector, comprising:

an inner insulating housing having a base portion, and a tongue portion protruding forward from a front of the base portion;

a plurality of terminals integrally molded to the inner insulating housing, each of the terminals having a contact portion longitudinally located in the tongue portion and exposed out of a bottom surface of the tongue portion, and a soldering portion projecting behind the base portion;

a shielding shell looped from a first metal plate with an inserting space being formed therein, the inner insulating housing together with the terminals being inserted into the inserting space of the shielding shell, a top of the shielding shell defining two buckling holes vertically penetrating therethrough;

a waterproof plate made of a second metal plate thinner than the first metal plate in thickness, the waterproof plate being fastened on the top of the shielding shell, two opposite sides of the waterproof plate being punched upward to form two receiving hats corresponding to the two buckling holes; and

an outer insulating housing integrally molded around the shielding shell, the waterproof plate and the base portion of the inner insulating housing with the soldering portions of the terminals projected outside.

2. The receptacle connector as claimed in claim 1, wherein the outer insulating housing has a top wall, two side walls, a bottom wall and a rear wall, the rear wall is molded around the base portion of the inner insulating housing and a rear end of the shielding shell.

3. The receptacle connector as claimed in claim 2, wherein the shielding shell has a top plate, a pair of lateral plates and a bottom plate, the shielding shell defines two arc-shaped matching grooves of which each passes through the joint of one lateral plate and the bottom plate, the outer insulating housing defines two matching portions of which each protrudes across the joint of one side wall and the bottom wall to be received in the corresponding matching groove.

4. The receptacle connector as claimed in claim 3, wherein two opposite sides of a rear edge of the top plate of the shielding shell extend downward and then are bent rearward to form two second soldering arms projecting behind the rear wall of the outer insulating housing, two upper inner sidewalls of the matching grooves of the shielding shell oppositely extend outward and then are bent downward to form a pair of first soldering arms projecting outside the corresponding side walls of the outer insulating housing.

5. The receptacle connector as claimed in claim 2, wherein the top wall defines two holes vertically penetrating therethrough and spaced from each other for making two uppermost surfaces of the two receiving hats of the waterproof plate flush with a top surface of the top wall of the outer insulating housing.

6. The receptacle connector as claimed in claim 2, wherein a restricting portion is protruded on a top of the base portion of the inner insulating housing, a rear edge of the top of the shielding shell is recessed forward to form a restricting groove for restricting the restricting portion therein, a top of the rear wall of the outer insulating housing is molded on the restricting portion.

7. The receptacle connector as claimed in claim 1, wherein a front of an outer periphery of the outer insulating housing protrudes outward to form a ring-shaped blocking rib for preventing the plug connector from being overly inserted into the inserting space of the receptacle connector.
