Abstract

An electrical receptacle connector includes a terminal module, an inner metallic shell, an outer insulation frame, and an outer metallic shell. The terminal module is assembled with the inner metallic shell and the outer insulation frame, the outer metallic shell is formed on the outer insulation frame, and the outer metallic shell is in contact with the inner metallic shell. The connector is provided with the outer insulation frame so as to prevent water moist entering into the other end of the outer insulation frame from one end of the outer insulation frame having the insertion opening. In addition, the outer metallic shell is formed on the outer insulation frame to improve the structural strength of the connector. Moreover, the outer metallic shell and the inner metallic shell are soldered with each other through the grooves of the outer insulation frame.

First claim

What is claimed is:

1. An electrical receptacle connector, comprising:
a terminal module comprising a base portion, a tongue portion a extended from one of two sides of the base portion, and a plurality of receptacle terminals, wherein the receptacle terminals are held on the base portion, one of two ends of each of the receptacle terminals is extended toward the tongue portion, and the other end of each of the receptacle terminals is protruded out of the base portion;
an inner metallic shell enclosing the base portion and surrounding an outer periphery of the tongue portion, wherein a front portion of the tongue portion is extended out of the inner metallic shell;
an outer insulation frame enclosing the inner metallic shell, wherein the outer insulation frame comprises a first inner wall surrounding an outer periphery of the inner metallic shell and a second inner wall forward extended from the first inner wall and surrounding the front portion of the tongue portion; and
an outer metallic shell formed on the first inner wall, wherein an inner surface of the outer metallic shell is in contact with an outer surface of the inner metallic shell.

2. The electrical receptacle connector according to claim 1 , wherein a plurality of contacts is formed on an outer surface of the outer metallic shell for soldering with the outer surface of the inner metallic shell, and the outer insulation frame comprises a plurality of grooves for soldering with the contacts.

3. The electrical receptacle connector according to claim 1 , wherein the first inner wall and the second wall are at different horizontal planes, and the second inner wall and the inner surface of the inner metallic shell are at a same horizontal plane.

4. The electrical receptacle connector according to claim 1 , wherein the inner metallic shell comprises a front tubular portion surrounding the outer periphery of the tongue portion and a rear tubular portion enclosing the base portion.

5. The electrical receptacle connector according to claim 4 , wherein the front tubular portion comprises a plurality of contact protrusions on an inner surface thereof.

6. The electrical receptacle connector according to claim 4 , wherein a plurality of bending sheets is extended from the rear tubular portion to abut against the other side of the base portion.

7. The electrical receptacle connector according to claim 4 , wherein a plurality of protruded blocks is formed on two sides of the rear tubular portion to abut against the outer insulation frame.

8. The electrical receptacle connector according to claim 1 , wherein a plurality of bending sheets is formed on two sides of a rear portion of the outer metallic shell and the bending sheets are bent to abut against the other side of the base portion.

9. The electrical receptacle connector according to claim 1 , further comprising a waterproof gasket fitted over an insertion opening of the outer insulation frame.

10. The electrical receptacle connector according to claim 1 , further comprising a grounding sheet in the base portion and the tongue portion.

11. The electrical receptacle connector according to claim 1 , wherein the receptacle terminals comprise a plurality of first receptacle terminals and a plurality of receptacle terminals held on the base portion and the tongue portion, the first receptacle terminals comprises a plurality of first signal terminals, a plurality of first power terminals, and a plurality of first ground terminals, the second receptacle terminals comprise a plurality of second signal terminals, a plurality of second power terminals, and a plurality of second ground terminals.

12. The electrical receptacle connector according to claim 11 , further comprising a plurality of grounding sheets respectively on the base portion and the tongue portion, one of the grounding sheets is between one of the first ground terminals and one of the second ground terminals, and another one of the grounding sheets is between another one of the first ground terminals and another one of the second ground terminals.

13. The electrical receptacle connector according to claim 1 , wherein the base portion and the tongue portion are formed by combining a first terminal base, a second terminal base, and a third terminal base, the first receptacle terminals are held on the first terminal base, the second receptacle terminals are held on the second terminal base.

14. The electrical receptacle connector according to claim 13 , wherein the second terminal base comprises a plurality of fixing grooves for positioning first tail portions of the first receptacle terminals.
