Abstract

An electrical receptacle connector includes a metallic shell and a terminal module in the metallic shell. One or more first leg extends outwardly from two sides of the metallic shell. A first slot is formed on the first leg. When the electrical receptacle connector is soldered to a circuit board, the first slot increases the space for receiving the solders to prevent solder wicking.

Claims

1. An electrical receptacle connector, comprising:

a terminal module comprising a base portion, a tongue portion extended outwardly from the base portion, and a plurality of receptacle terminals held in the base portion, wherein one of two ends of each of the receptacle terminals extends toward the tongue portion, and the other end of each of the receptacle terminals protrudes out of the base portion, wherein the receptacle terminals comprise a plurality of first receptacle terminals and a plurality of second receptacle terminals, the first receptacle terminals and the second receptacle terminals are held in the base portion and the tongue portion, first flat contact portions of the first receptacle terminals at one ends of the first receptacle terminals are at the first surface of the tongue portion, and second flat contact portions of the second receptacle terminals at one ends of the second receptacle terminals are at the second surface of the tongue portion;

a metallic shell receiving the terminal module, wherein each of two sides of the metallic shell extends outwardly at least one first leg, and each of the first legs forms a first slot, wherein each of the first legs comprises a first main body and the first slot is defined through the first main body from two opposite surfaces to the other surface, and the first slot is a closed space; and

a shielding plate held inside the base portion and the tongue portion, wherein the shielding plate comprises a plate body and at least one shielding leg, the plate body is between the first flat contact portions and the second flat contact portions, the at least one shielding leg extends outwardly from one of two sides of the plate body, the at least one shielding leg is near an inner side of the corresponding first leg and aligned with the corresponding first leg.

2. The electrical receptacle connector according to claim 1, wherein the metallic shell comprises a plurality of side plates, a top plate, and a bottom plate, the side plates respectively locate adjacent to two sides of the tongue portion, the top plate locates adjacent to a first surface of the tongue portion, and the bottom plate locates adjacent to a second surface of the tongue portion opposite to the first surface, the side plates, the top plate, and the bottom plate are connected with each other to form an insertion opening of the metallic shell and the insertion opening is near a front end of the tongue portion.

3. The electrical receptacle connector according to claim 2, further comprising an outer shell out of the metallic shell and near the insertion opening, wherein the outer shell stacks on the metallic shell to form a double-layer shell structure.

4. The electrical receptacle connector according to claim 3, wherein the metallic shell comprises a front region and a rear region defined at the bottom plate and located at a rear portion of the front region.

5. The electrical receptacle connector according to claim 4, wherein the outer shell comprises a plurality of sidewalls and a plurality of second legs, the sidewalls respectively extend toward two sides of the rear region, and the second legs respectively extend outwardly from edges of the sidewalls.

6. The electrical receptacle connector according to claim 5, wherein one of the second legs on each of the sidewalls is near an outer side of the corresponding first leg and aligned with the corresponding first leg.

7. The electrical receptacle connector according to claim 5, wherein each of the second legs comprises a second main body and a second slot formed on the second main body.

8. The electrical receptacle connector according to claim 7, wherein each of the second legs comprises a plurality of second recessed portions, and the second recessed portions are formed at two sides of the second main body.

9. The electrical receptacle connector according to claim 8, wherein the second main body further comprises a second bottom wall and two second slit side walls, the two second slit side walls are at two opposite sides of the second main body, respectively, each of two second slit side walls are extended from one end of second recessed portion and connected to one side of the second bottom wall, such that a width of second main body is gradually reduced from the second recessed portion to the second bottom wall.

10. The electrical receptacle connector according to claim 5, wherein the second legs at front portions of the sidewalls are aligned along a first horizontal line, the second legs at rear portions of the sidewalls are aligned along a second horizontal line and near the two sides of the base portion.

11. The electrical receptacle connector according to claim 3, wherein the outer shell comprises a top portion, a bottom portion, and two side portions each connected to the top portion and the bottom portion, the top portion, the bottom portion, and the two side portions form a receiving space for receiving the metallic shell.

12. The electrical receptacle connector according to claim 3, wherein the outer shell comprises a top portion and two side portions respectively extended from two sides of the top portion, the top portion and the two side portions form an assembling space for stacking on the metallic shell.

13. The electrical receptacle connector according to claim 1, wherein the base portion comprises a plurality of positioning posts, each of the positioning posts is near the corresponding first leg.

14. The electrical receptacle connector according to claim 1, wherein a rear cover and a plurality of first legs extend from a rear portion of the metallic shell, the first legs extend outwardly from two sides of the rear cover.

15. The electrical receptacle connector according to claim 1, wherein each of the first legs further comprises a plurality of first recessed portions, the first recessed portions are formed at two sides of the first main body, the first main body comprises a first bottom wall and two first slit side walls, the two first slit side walls are at two opposite sides of the first main body, respectively, each of two first slit side walls are extended from one end of first recessed portion and connected to one side of the first bottom wall, and a width of first main body is gradually reduced from the first recessed portion to the first bottom wall.
