Abstract

A waterproof electrical receptacle connector includes an insulated housing, a metallic shell, and a sealing member (e.g., a waterproof glue block). The insulated housing includes a base portion and a tongue portion extended from one side of the base portion. The metallic shell includes a tubular portion and an outer peripheral portion. The outer peripheral portion is formed by deep drawing techniques and extended from the rear of the tubular portion. The inner diameter of the outer peripheral portion is greater than the inner diameter of the tubular portion. A filling groove is formed between the inner wall of the outer peripheral portion and the outer surface of the base portion. The sealing member is formed at the filling groove to fill a gap between the inner wall of the outer peripheral portion and the outer surface of the base portion and fill the bottom of the base portion.

Claims

1. A waterproof electrical receptacle connector, comprising:

an insulated housing comprising a base portion and a tongue portion extended from one side of the base portion, wherein the tongue portion has an upper surface and a lower surface opposite to the upper surface;

a plurality of first receptacle terminals comprising a plurality of first signal terminals, at least one first power terminal, and at least one first ground terminal, wherein each of the first receptacle terminals is held in the insulated housing and disposed at the upper surface;

a metallic shell defining a receiving cavity for receiving the base portion and the tongue portion, wherein the metallic shell comprises a tubular portion and an outer peripheral portion, the outer peripheral portion is formed by deep drawing techniques and extended from the rear of the tubular portion, wherein the inner diameter of the outer peripheral portion is greater than the inner diameter of the tubular portion, and a filling groove is formed between the inner wall of the outer peripheral portion and the outer surface of the base portion; and

a sealing member formed at the filling groove to fill a gap between the inner wall of the outer peripheral portion and the outer surface of the base portion and to fill a bottom of the base portion.

2. The waterproof electrical receptacle connector according to claim 1, further comprising a plurality of second receptacle terminals, wherein the second receptacle terminals comprise a plurality of second signal terminals, at least one second power terminal, and at least one second ground terminal, wherein each of the second receptacle terminals is held in the insulated housing and disposed at the tongue portion, one of two ends of each of the second receptacle terminals is disposed at the lower surface, and the other end of each of the second receptacle terminals is protruded from the bottom of the base portion.

3. The waterproof electrical receptacle connector according to claim 2, wherein the first receptacle terminals and the second receptacle terminals have 180 degree symmetrical design with respect to a central point of the receiving cavity as the symmetrical center.

4. The waterproof electrical receptacle connector according to claim 2, wherein each of the second receptacle terminals comprises a second flat contact portion, a second body portion, and a second tail portion, wherein the second body portions are held in the base portion and disposed at the lower surface of the tongue portion, each of the second flat contact portions is extended from one of two ends of the corresponding second body portion and disposed at the lower surface of the tongue portion, and each of the second tail portions is extended from the other end of the corresponding second body portion and exposed out of the base portion.

5. The waterproof electrical receptacle connector according to claim 1, wherein the rear of the base is protruded from the outer peripheral portion, the metallic shell comprises a rear lid located at the rear of the outer peripheral portion to enclose the base portion.

6. The waterproof electrical receptacle connector according to claim 5, wherein the metallic shell comprises a filling section formed between the inner wall of the rear lid and the outer surface of the base portion, the filling section is extended from one of two sides of the base portion, through the top of the base portion, and extended to the other side of the base portion, the sealing member is filled in the filling section.

7. The waterproof electrical receptacle connector according to claim 5, wherein the rear lid comprises a plurality of hook portions, the base portion comprises a plurality of recessed portions, each of the hook portions is engaged with the corresponding recessed portion.

8. The waterproof electrical receptacle connector according to claim 1, further comprising an outer shell enclosing the tubular portion, wherein the outer shell comprises two legs respectively extended to two sides of the tubular portion.

9. The waterproof electrical receptacle connector according to claim 1, wherein each of the first receptacle terminals comprises a first flat contact portion, a first body portion, and a first tail portion, wherein the first body portions are held in the base portion and disposed at the upper surface of the tongue portion, each of the first flat contact portions is extended from one of two ends of the corresponding first body portion and disposed at the upper surface of the tongue portion, and each of the first tail portions is extended from the other end of the corresponding first body portion and exposed out of the base portion.

10. The waterproof electrical receptacle connector according to claim 1, further comprising a grounding plate disposed at the insulated housing.
