Abstract

An electrical connector includes: an insulative housing comprising a base portion and a tongue portion extending forwardly from the base portion; a number of upper and low terminals mounted in the insulative housing and exposed to an upper surface and a lower surface of the tongue portion, the upper terminals and the lower terminals being equal in number, both the upper terminals and the lower terminals comprising five intermediate terminals arranged centrally in succession and one grounding terminal spaced from the five intermediate terminals by two terminal positions, each of the five intermediate terminals having a reserved space for not arranging a terminal, the five intermediate terminals comprising an auxiliary terminal; and a shielding plate disposed between the upper terminals and the lower terminals.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing comprising a base portion and a tongue portion extending forwardly from the base portion;
a plurality of upper and lower terminals mounted in the insulative housing and exposed to an upper surface and a lower surface of the tongue portion, the upper terminals and the lower terminals being equal in number, both the upper terminals and the lower terminals comprising five intermediate terminals arranged centrally in succession and one grounding terminal spaced from the five intermediate terminals by two terminal positions, a respective reserved space being formed between every two adjacent terminals of the five intermediate terminals, the five intermediate terminals comprising an auxiliary terminal; and
a shielding plate disposed between the upper terminals and the lower terminals, wherein
each terminal comprises a contacting portion exposed to the tongue portion, a fixing portion affixed to the insulative housing, and a soldering portion extending out of the insulative housing, and both the plurality of upper and lower terminals comprise a plurality of first contacts each having an ear extending laterally from the contacting portion for resisting against a mold, and the ears of the plurality of first contacts of the upper terminals are offset from the ears of the plurality of first contacts of the lower terminals in a front-to-rear direction.

2. The electrical connector as claimed in claim 1 , wherein the upper terminals are arranged in one row and the lower terminals are arranged in another row, and each row of terminals consists of seven terminals comprising the five intermediate terminals.

3. The electrical connector as claimed in claim 1 , wherein the tongue portion comprises twelve terminal positions at each of the upper and lower surfaces, and the five intermediate terminals in each of the upper terminals and the lower terminals are affixed at the tongue portion from a fifth position of the twelve terminal positions to a ninth position of the twelve terminal positions and consists of a detecting terminal, a USB2.0 positive signal terminal, a USB2.0 negative signal terminal, the auxiliary terminal, and a power terminal.

4. The electrical connector as claimed in claim 1 , wherein the shielding plate is sandwiched between the upper terminals and the lower terminals, the shielding plate comprises a main portion having a right portion, a left portion arranged in symmetry with the right portion and a connecting arm, and the connecting arm is offset from the ear in the front-to-rear direction.

5. The electrical connector as claimed in claim 1 , wherein each first contact comprises a front portion extending forwardly from the contacting portion and having a resisting space, and the front portions of the upper terminals are laterally offset from the front portions of the lower terminals in a transverse direction perpendicular to the front-to-rear direction.

6. The electrical connector as claimed in claim 1 , wherein the insulative housing comprises a first insulator and a second insulator, the first insulator, the upper terminals, the lower terminals, and the shielding plate are insert molded to be an integrated unit, the first insulator further includes a plurality of resisting grooves, and each contacting portion is partially exposed to the resisting groove.

7. The electrical connector as claimed in claim 6 , wherein the second insulator is insert molded with the integrated unit to form the insulative housing.

8. The electrical connector as claimed in claim 1 , further comprising a shielding shell enclosing the insulative housing for forming a mating room.

9. The electrical connector as claimed in claim 1 , wherein the five intermediate terminals are affixed at the tongue portion from the fifth position to the ninth position and comprise a detecting terminal, a USB2.0 positive signal terminal, a USB2.0 negative signal terminal, the auxiliary terminal, and a power terminal.

10. An electrical connector comprising:
an insulative housing including a base portion and a tongue forwardly extending from the base portion in a front-to-back direction, said tongue portion forming opposite first and second surfaces thereon in a vertical direction perpendicular to said front-to-back direction;
a plurality of first contacts disposed in the housing, each of said first contacts including along the front-to-back direction a first front contacting section exposed upon the first surface, and a first rear tail section exposed outside of the housing, the first front contacting section of each of said first contacts including a first left ear and a first right ear respectively formed on two opposite sides thereof in a transverse direction perpendicular to both said front-to-back direction and said vertical direction;
a plurality of second contacts disposed in the housing, each of the second contacts including along the front-to-back direction a second front contacting section exposed upon the second surface, and a second rear tail section exposed outside of the housing, the second front contacting section of each of said second contacts including a second left ear and a second right ear respectively formed on two opposite sides thereof in the transverse direction; and
a metallic shielding plate located between the first contacts and the second contacts in the vertical direction; wherein
in each of the first contacts the first left ear is offset from the first right ear in the front-to-back direction; in each of said second contacts the second left ear is offset from the second right ear in the front-to-back direction; wherein
the first left ear and the first right ear of each of said first contacts are offset from the second left ear and the second right ear of each of said second contacts in the front-to-back direction.

11. The electrical connector as claimed in claim 10 , wherein the first contacting sections of some of said first contacts are essentially aligned with the second contacting section of some corresponding second contacts in the vertical direction except that front end regions of said some of the first contacting sections are offset from those of the corresponding second contacting sections in both the front-to-back direction and the transverse direction.

12. The electrical connector as claimed in claim 11 , wherein the insulative housing includes a first insulator initially enclosing the first contacts, the second contacts and the shielding plate via an insert-molding process, and a second insulator successively applied upon the first insulator, and the front end regions of said some of the first contacting sections are hidden behind the first insulator while the front end regions of the corresponding second contacting sections are exposed outside of the first insulator.

13. The electrical connector as claimed in claim 12 , wherein the front end regions of both said some the first contacting sections and those of the corresponding second contacting sections are hidden behind the second insulator.

14. The electrical connector as claimed in claim 12 , wherein the front end regions of said some of the first contacting sections are aligned with main portions of said some of the first contacting sections while the front end regions of the corresponding second contacting sections are offset from main portions of the corresponding second contacts in the transverse direction.
