Abstract

A electrical connector ( 100 ) includes an insulative housing ( 1 ), a number of terminals ( 2 ), a stiffener ( 3 ) and a pair of insulative members ( 4 ). The insulative housing includes a tongue portion ( 11 ) defining a number of first passageways ( 111 a ) and two molding holes ( 115 a, 115 b ) communicating with the first passageways for accommodating a number of molds. The stiffener is insert molded with the insulative housing and defines two openings ( 33 a, 33 b ) communicating with the molding holes. The insulative members cover the openings for sealing the molding holes after removal of the molds.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing including a base portion and a tongue portion extending forwardly therefrom in a front-to-back direction;
a plurality of immovable terminals embedded within the housing via an insert-molding process, the tongue portion defining a plurality of passageways arranged with one another in a transverse direction perpendicular to said front-to-back direction to receive said immovable terminals therein, and a plurality of molding holes communicating with said passageways in a vertical direction perpendicular to both said front-to-back direction and said transverse direction for receiving corresponding molds during said insert-molding process;
a metallic stiffener embedded in the tongue portion, said stiffener including an opening: and
an insulative block including a plurality of parts filled within the corresponding molding holes through the opening of the stiffener; wherein
the tongue portion defines opposite surfaces in the vertical direction, and the immovable terminals are exposed upon one surface while the insulative block and the stiffener are exposed upon the other surface.

2. The electrical connector as claimed in claim 1 , wherein said insulative block is formed by another molding process.

3. The electrical connector as claimed in claim 1 , further including a metallic shell enclosing the housing, and wherein said shell defines a receiving cavity in which the tongue portion extends forwardly.

4. The electrical connector as claimed in claim 1 , further including a plurality of deflectable terminals integrally molded within a positioning structure which is attached to the housing, and wherein said deflectable terminals are essentially located behind the immovable terminals in the front-to-back direction.

5. The electrical connector as claimed in claim 1 , wherein said molding holes are fully occupied by the insulative block.

6. An electrical connector comprising:
an insulative housing including a base portion and a tongue portion extending forwardly therefrom in a front-to-back direction;
a plurality of immovable terminals embedded within the housing via an insert-molding process, the tongue portion defining a plurality of passageways arranged with one another in a transverse direction perpendicular to said front-to-back direction to receive said immovable terminals therein, and a plurality of molding holes communicating with said passageways in a vertical direction perpendicular to both said front-to-back direction and said transverse direction for receiving corresponding molds during said insert-molding process; and
an insulative block including a plurality of parts filled within and completely occupying the corresponding molding holes after the insert-molding process for preventing shorting; wherein
both said immovable terminals and said insulative block are exposed to an exterior in the vertical direction while said molding holes are not exposed to the exterior in the vertical direction but covered by the insulative block; and
a metallic stiffener embedded within the tongue portion, wherein said stiffener includes an opening set aligning with the molding holes for molding consideration.

7. The electrical connector as claimed in claim 6 , wherein said insulative block is formed by another molding process upon the housing.

8. The electrical connector as claimed in claim 7 , wherein said insulative block includes a plurality of projections extending into the molding holes along the front-to-back direction and unexposed to the exterior in the vertical direction.

9. The electrical connector as claimed in claim 7 , wherein the tongue portion defines opposite surfaces in the vertical direction, and the immovable terminals are exposed upon one surface while the insulative block is exposed upon the other surface.

10. The electrical connector as claimed in claim 6 , wherein said stiffener is exposed upon one surface of the mating tongue in the vertical direction.

11. The electrical connector as claimed in claim 6 , wherein further including a metallic shell enclosing the housing, wherein said shell defines a receiving cavity in which the tongue portion extends forwardly.

12. The electrical connector as claimed in claim 11 , further including a plurality of deflectable terminals integrally molded within a positioning structure which is attached to the housing, wherein said deflectable terminals are essentially located behind the immovable terminals in the front-to-back direction.
