Abstract

An electrical connector includes an insulative housing, a number of terminals disposed in the insulative housing, a metallic shielding plate, a shielding shell defining a mating cavity, and a metal shell. The insulative housing defines a base portion and a tongue portion extending forwardly from the base portion. The base portion includes a front side, a rear side opposite to the front side, at least one retaining slot located in the front side of the base portion. The shielding shell includes at least one front stopping portion protruding into the mating cavity and received in the retaining slot, the at least one front stopping portion includes a front surface located beyond the front side of the base portion to prevent damage the base portion when a mating connector inserting into the electrical connector.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing defining a base portion and a tongue portion forwardly extending from the base portion in a front-to-back direction, the base portion defining a front side, a rear side opposite to the front side, and at least one retaining slot located in the front side;
a plurality of terminals disposed in the insulative housing;
a metallic shielding plate retained in the insulative housing; and
a shielding shell enclosing the insulative housing to form a mating cavity receiving the base portion, the shielding shell defining at least one front stopping portion inwardly protruding into the mating cavity and received in the at least one retaining slot;
wherein the at least one front stopping portion has a front surface forwardly protruding out of the at least one retaining slot and forwardly extending beyond the front side of the base portion into the mating cavity.

2. The electrical connector as claimed in claim 1 , wherein the terminals include a plurality of first terminals and a plurality of second terminals positioned to have 180 degree symmetry with the first terminals, each first terminal partly exposed to the upper surface of the tongue portion, each second terminal partly exposed to the bottom surface of the tongue portion, the first terminals including a pair of first grounding terminals located on opposite sides, the second terminals including a pair of second grounding terminals located on opposite sides and electrically connecting with the first grounding terminals respectively.

3. The electrical connector as claimed in claim 1 , wherein the shielding shell further includes a pair of rear stopping portions located on a rear end thereof, each rear stopping portion engaged with the rear side of the base portion.

4. The electrical connector as claimed in claim 1 , wherein the shielding shell defines an upper wall and a bottom wall opposite to the upper wall, the at least one front stopping portion includes at least one upper stopping portion located on the upper wall and at least one bottom stopping portion located on the bottom wall, and the upper stopping portion and the bottom stopping portion have a respective arc-shaped section from the upper wall and the bottom wall, an opening formed at the arc-shaped section on the upper wall and the bottom wall.

5. The electrical connector as claimed in claim 4 , wherein the at least one retaining slot includes an upper retaining slot and a pair of bottom retaining slots, the upper retaining slot located at a middle position of an upper edge of the front side and the pair of bottom retaining slots located at a bottom edge of the front side, the pair of bottom retaining slots located on opposite sides of the upper retaining slot, the at least one upper stopping portion includes only one upper stopping portion cooperating with the upper retaining slot, and the at least one bottom stopping portion includes a pair of bottom stopping portions cooperating with the pair of bottom retaining slots respectively.

6. The electrical connector as claimed in claim 4 , further comprising a plurality of waterproof plates attached to the upper wall and the bottom wall to close the opening.

7. The electrical connector as claimed in claim 6 , further comprising a metal shell formed with a receiving cavity to receive the shielding shell, and wherein the metal shell includes an upper plate portion and a bottom plate portion each having a plurality of protruding portions protruding into the receiving cavity, and the protruding portion holds the shielding shell.

8. The electrical connector as claimed in claim 7 , wherein each protruding portion is spaced from the waterproof plates.

9. The electrical connector as claimed in claim 8 , wherein the protruding portions of the metal shell is soldered to the shielding shell.

10. The electrical connector as claimed in claim 8 , wherein each of the upper plate portion and the bottom plate portion includes two rows of the protruding portions, and each row of the protruding portions is located on an outer side of the waterproof plate in a transverse direction perpendicular to the front-to-back direction.

11. An electrical connector comprising:
an insulative housing including a base portion and a tongue portion extending forwardly from the base portion;
a plurality of upper terminals disposed in the housing with contacting sections exposed upon an upper surface of the tongue portion;
a plurality of lower terminals disposed in the housing with contacting sections exposed upon a lower surface of the tongue portion;
a tubular metallic shielding shell enclosing the insulative housing and defining a mating cavity in which said tongue portion extends, said shielding shell further forming at least a front stopping portion to prevent forward movement of the housing relative to the shielding shell, and a rear stopping portion to prevent rearward movement of the housing relative to the shielding shell;
a tubular metal shell enclosing said shielding shell and including an extension covering a rear side of the base portion, and a plurality of protruding portions inwardly and vertically abutting against and soldered to the shielding shell for securing the metal shell and said shielding shell together.

12. The electrical connector as claimed in claim 11 , wherein said metal shell further includes mounting legs for mounting to a printed circuit board while said shielding shell lacks mounting legs.

13. The electrical connector as claimed in claim 11 , wherein said front stopping portion is stamped from the shielding metal and received within a corresponding recess of the base portion.

14. The electrical connector as claimed in claim 13 , further including a waterproof layer sandwiched between the shielding shell and the metal shell to cover an opening formed around the front stopping portion due to stamping, while said waterproof layer extends transversely not to reach the protruding portions.

15. The electrical connector as claimed in claim 14 , wherein said shielding shell further includes a plurality of curved portions inwardly extending into the mating cavity in a vertical direction for mating with a plug connector, and said waterproof layer extend transversely not to reach the curved portions.

16. The electrical connector as claimed in claim 11 , wherein said base portion forms a plurality of through holes to cooperate with at least an opening in the extension of the metal shell for allowing downwardly inspecting tails of the lower terminals in a vertical direction.

17. An electrical connector comprising
an insulative housing including a base portion and a tongue portion extending forwardly from the base portion;
a plurality of upper terminals disposed in the housing with contacting sections exposed upon an upper surface of the tongue portion;
a plurality of lower terminals disposed in the housing with contacting sections exposed upon a lower surface of the tongue portion;
a tubular metallic shielding shell enclosing the insulative housing and defining a mating cavity in which said tongue portion extends, said shielding shell further forming at least a front stopping portion to prevent forward movement of the housing relative to the shielding shell; and
a tubular metal shell enclosing said shielding shell and including an extension covering a rear side of the base portion, and a plurality of protruding portions inwardly and vertically abutting against and soldered to the shielding shell for securing the metal shell and said shielding shell together; wherein
