Abstract

An electrical receptacle connector includes a terminal module and a plurality of shielding plates. The terminal module includes a base portion, a tongue portion outward extended from one of two sides of the base portion, and a plurality of receptacle terminals. The receptacle terminals are held on the base portion. One of the shielding plates is between one of the first ground terminals and one of the second ground terminals, and another one of the shielding plates is between another one of the first ground terminals and another one of the second ground terminals. Accordingly, when the tongue portion is worn by repeated plug-and-pull operations, the signal terminals of the receptacle terminals are not in contact with the shielding plate to prevent the short circuit problem.

Claims

1. An electrical receptacle connector, comprising:

a terminal module comprising a base portion, a tongue portion 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 end of each of the receptacle terminals is extended toward a front portion of the tongue portion, and the other end of each of the receptacle terminals is protruded out of the base portion, the receptacle terminals comprises a plurality of first receptacle terminals and a plurality of second receptacle terminals which are held on the base portion and the tongue portion, first flat contact portions of the first receptacle terminals are held on one of two opposite surfaces of the tongue portion, and second flat contact portions of the second receptacle terminals are held on the other surface of the tongue portion, first receptacle terminals comprises a plurality of first ground terminals, and second receptacle terminals comprises a plurality of second ground terminals; and

a plurality of shielding plates embedded within the tongue portion, wherein one of the shielding plates is disposed between one of the first ground terminals and one of the second ground terminals, and another one of the shielding plates is disposed between another one of the first ground terminals and another one of the second ground terminals.

2. The electrical receptacle connector according to claim 1, wherein, the first receptacle terminals further comprise a plurality of first signal terminals and a plurality of first power terminal and the second receptacle terminals further comprise a plurality of second signal terminals and a plurality of second power terminals.

3. The electrical receptacle connector according to claim 1, further comprising an inner metallic shell enclosing the base portion and surrounding an outer periphery of the tongue portion, a front portion of the tongue portion is extended out of the inner metallic shell.

4. The electrical receptacle connector according to claim 3, 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, further comprising 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.

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

9. The electrical receptacle connector according to claim 7, 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.

10. The electrical receptacle connector according to claim 7, further comprising a waterproof gasket fitted over an insertion opening of the outer insulation frame.
