Abstract

An electrical connector includes an insulative housing, a plurality of conductive terminals and a metal shell. The housing includes a base portion, a tongue protruding forwardly from the base portion and a terminal fixing portion positioned behind the base portion; a groove is provided between the base portion and the fixing portion to allow glue to fill therein; the fixing portion is provided with at least one fencing portion at a side of the fixing portion adjacent to the groove, the fencing portion is formed with a hollow recessed groove therein. The terminals are provided to the housing; each terminal includes a mating portion exposed on the tongue, a soldering portion extending out of the fixing portion and a connecting portion connected between the mating portion and the soldering portion; a part of the connecting portion is exposed to the groove. The shell sheathes an outer circumference of the housing.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing which comprises a base portion, a mating tongue protruding forwardly from the base portion and a terminal fixing portion positioned behind the base portion;
a glue receiving groove between the base portion and the terminal fixing portion and configured to allow a glue to fill therein;
a fencing portion formed in the insulative housing and provided at a side of the glue receiving groove, the fencing portion being formed by a front partitioning wall and a side partitioning wall which forms a hollow recessed groove therein which is in direct fluid communication with the glue receiving groove such that the hollow recessed groove is configured to receive a flow of glue from the glue receiving groove;
a plurality of conductive terminals, each conductive terminal including a mating portion exposed on the mating tongue, a soldering portion extending out of the terminal fixing portion and a connecting portion connected between the mating portion and the soldering portion, and wherein a part of the connecting portion is exposed to the glue receiving groove; and
a first shell sheathing an outer circumference of the insulative housing and forms a mating cavity which surrounds the mating tongue therein.

2. The electrical connector according to claim 1 , wherein the fencing portion is provided at a bottom surface of the insulative housing, and an opening of the hollow recessed groove faces downwardly.

3. The electrical connector according to claim 2 , wherein a middle of the glue receiving groove has a recessed portion protruding therefrom, the recessed portion having opposite sides and penetrating the insulative housing from an upper side of the insulative housing to a lower side of the insulative housing; and
wherein the fencing portion is provided at each side of the recessed portion.

4. The electrical connector according to claim 3 , wherein each fencing portion is provided in the terminal fixing portion and comprises a front partitioning wall and a side partitioning wall, wherein the front partitioning wall faces the base portion, the side partitioning wall is positioned to one side of the recessed portion, and the front partitioning wall and the side partitioning wall encircle the hollow recessed groove from outside.

5. The electrical connector according to claim 1 , wherein the fencing portion is configured to deform to absorb deformation of the glue.

6. The electrical connector according to claim 1 , wherein the shell is metal.

7. The electrical connector according to claim 1 , wherein the fencing portion is formed in the terminal fixing portion.

8. The electrical connector according to claim 3 , wherein the recessed portion penetrates the terminal fixing portion from an upper side of the terminal fixing portion to a lower side of the terminal fixing portion.

9. An electrical connector comprising:
an insulative housing which comprises a base portion, a mating tongue protruding forwardly from the base portion and a terminal fixing portion positioned behind the base portion;
a glue receiving groove between the base portion and the terminal fixing portion and configured to allow a glue to fill therein;
a fencing portion formed in the insulative housing and provided at a side of the glue receiving groove, the fencing portion comprising a deformable wall which forms a hollow recessed groove in the insulative housing;
a plurality of conductive terminals, each conductive terminal including a mating portion exposed on the mating tongue, a soldering portion extending out of the terminal fixing portion and a connecting portion connected between the mating portion and the soldering portion, wherein a part of the connecting portion is exposed to the glue receiving groove; and
a first shell sheathing an outer circumference of the insulative housing and forms a mating cavity which surrounds the mating tongue therein.

10. The electrical connector according to claim 9 ,
further comprising two metal fixing parts respectively fixed to an upper side and a lower side of the insulative housing, each metal fixing part including a horizontal protecting portion having a first thickness and a horizontal fixing portion having a second thickness, the first thickness is less than the second thickness, the horizontal protecting portion covers a surface of a rear portion of the mating tongue, and the horizontal fixing portion is inserted into a surface of the base portion, and welded with the first shell together.

11. The electrical connector according to claim 9 ,
further comprising a second fixing shell fixed to the first shell, the second fixing shell including a top plate and two side plates respectively bending from two sides of the top plate, two positioning flanges protrude from one side plate of the two side plates respectively toward an upper side and a lower side of the one side plate; and
a fixing piece extends out from the other side plate of the two side plates, the fixing piece is provided with a fixing aperture.

12. The electrical connector according to claim 9 , wherein the base portion of the insulative housing and the terminal fixing portion are connected together by two connecting ribs respectively positioned at two sides of the glue receiving groove.

13. The electrical connector according to claim 9 , wherein the fencing portion is provided at a bottom surface of the insulative housing, and an opening of the hollow recessed groove faces downwardly.

14. The electrical connector according to claim 13 , wherein a middle of the glue receiving groove has a recessed portion protruding therefrom, the recessed portion having opposite sides and penetrating the insulative housing from an upper side of the insulative housing to a lower side of the insulative housing; and
the fencing portion is provided at each side of the recessed portion.

15. The electrical connector according to claim 14 , wherein the recessed portion penetrates the terminal fixing portion from an upper side of the terminal fixing portion to a lower side of the terminal fixing portion.

16. The electrical connector according to claim 9 , wherein the first shell is metal.

17. The electrical connector according to claim 9 , wherein the fencing portion is formed in the terminal fixing portion.

18. An electrical connector comprising:
an insulative housing including a base portion, a mating tongue protruding forwardly from the base portion and a terminal fixing portion positioned rearward of the base portion;
a glue receiving groove between the base portion and the terminal fixing portion and which is configured to allow a glue to fill therein, a middle of the glue receiving groove having a recessed portion having opposite sides, the recessed portion penetrating the insulative housing from an upper side of the insulative housing to a lower side of the insulative housing;
a fencing portion provided at each side of the recessed portion, each fencing portion being positioned at the lower side of the insulative housing, each fencing portion defining a hollow recessed groove which has an opening facing downwardly;
