Abstract

An electrical connector includes: an insulative housing having a base portion and a tongue portion; plural contacts affixed to the insulative housing and exposed to the tongue portion; a shielding shell enclosing the insulative housing and having a front end; an outer cover enclosing the shielding shell and having a front protrusion, the front protrusion having a pair of side slots; and a sealer having a main body and a pair of side securing portions; wherein an annular groove is defined between the front end of the shielding shell and the front protrusion of the outer cover, the front protrusion of the outer cover having a first inclined face bordering the groove; and the sealer main body is disposed in the groove and the side securing portions engage the side slots, the sealer main body having a second inclined face opposing the first inclined face.

Claims

1. An electrical connector comprising:

an insulative housing having a base portion and a tongue portion;

a plurality of contacts affixed to the insulative housing and exposed to the tongue portion;

a shielding shell enclosing the insulative housing and having a front end;

an outer cover enclosing the shielding shell and having a front protrusion, the front protrusion having a pair of side slots; and

a sealer having a main body and a pair of side securing portions;

wherein an annular groove is defined between the front end of the shielding shell and the front protrusion of the outer cover, the front protrusion of the outer cover having a first inclined face bordering the groove; and

the sealer main body is disposed in the groove and the side securing portions engage the side slots, the sealer main body having a second inclined face opposing the first inclined face.

2. The electrical connector as claimed in claim 1, wherein the first inclined face of the outer cover front protrusion is planar.

3. The electrical connector as claimed in claim 1, wherein the front protrusion of the outer cover has a pair of first inclined faces on an upper part and a low part thereof, respectively.

4. The electrical connector as claimed in claim 1, wherein the sealer has a rear annular part received within the annular groove and a front annular part abutting the front protrusion of the outer cover.

5. An electrical connector comprising:

an insulative housing;

a plurality of contacts affixed to the insulative housing;

a shielding shell enclosing the insulative housing, forming a mating cavity, and having a front end;

an outer cover enclosing the shielding shell and having a front protrusion;

an annular groove defined between the front end of the shielding shell and the front protrusion of the outer cover, the front protrusion of the outer cover having a first inclined face bordering the groove; and

a front sealer having a main body disposed in the groove, the main body of the front sealer forming a second inclined face intimately engaged with the first inclined face;

wherein

both said first inclined face and the second inclined face extend forwardly toward a mid-level of the mating cavity.

6. The electrical connector as claimed in claim 5, wherein the outer cover forms a groove located behind and communicating with the annular groove in a front-to-back direction.

7. The electrical connector as claimed in claim 5, wherein the first inclined face of the outer cover front protrusion is planar.

8. The electrical connector as claimed in claim 5, wherein the front protrusion of the outer cover has a pair of first inclined faces on an upper part and a low part thereof, respectively.

9. The electrical connector as claimed in claim 5, wherein the front sealer has a rear annular part received within the annular groove and a front annular part abutting the front protrusion of the outer cover.

10. The electrical connector as claimed in claim 5, wherein the main body of the front sealer further forms a straight horizontal surface abutting against another straight horizontal surface of the shielding shell so as to have the main part tightly sandwiched between the front protrusion of the outer cover and the front end of the shielding shell.

11. An electrical connector comprising:

an insulative housing;

a plurality of contacts affixed to the insulative housing;

a shielding shell enclosing the insulative housing, forming a mating cavity, and having a front end;

an outer cover enclosing the shielding shell and having a front protrusion;

an annular groove defined within the front protrusion and having a first inclined face bordering the groove; and

a front sealer having a main body disposed in the groove, the main body of the front sealer forming a second inclined face intimately engaged with the first inclined face;

wherein

both said first inclined face and the second inclined face extend forwardly toward a mid-level of the mating cavity.

12. The electrical connector as claimed in claim 11, wherein the outer cover forms a groove located behind and communicating with the annular groove in a front-to-back direction.

13. The electrical connector as claimed in claim 11, wherein the first inclined face of the outer cover front protrusion is planar.

14. The electrical connector as claimed in claim 11, wherein the front protrusion of the outer cover has a pair of first inclined faces on an upper part and a low part thereof, respectively.

15. The electrical connector as claimed in claim 14, wherein the front sealer has a rear annular part received within the annular groove and a front annular part abutting the front protrusion of the outer cover.

16. The electrical connector as claimed in claim 11, wherein the main body of the front sealer further forms a straight horizontal surface abutting against another straight horizontal surface of the shielding shell.
