Abstract

An electrical connector (100) includes an insulative housing (1), a number of terminals (2), and a stiffener (3). The insulative housing includes a tongue portion (12) defining a number of passageways (121), a first indentation (123) opened upwardly and extending through an upper portion and a side portion of the tongue portion. One outermost terminal (20) has an upper surface and a side surface resisted against by a first mold and partly exposed outwardly via the first indentation and the opening after removal of the first mold. Also disclosed is a compression mount electrical connector including a shell and a grounding member secured to the shell and similarly configured as terminals thereof.

Claims

1. An electrical connector comprising:

an insulative housing including a base portion and a tongue portion extending forwardly from the base portion, said tongue portion having an upper portion, a lower portion, a pair of side portions, and a plurality of passageways at the lower portion, said tongue portion defining a pair of first indentations each exposing upwardly and through the upper portion and the side portion for accommodating a first mold;

a plurality of terminals including a pair of outermost terminals, each terminal having a body portion secured in the passageways of the insulative housing; and

a stiffener attached to the upper portion of the tongue portion and defining a pair of openings aligning with the first indentations respectively, said body portion of each outermost terminal having an upper surface and a side surface for being resisted against by the first mold and partly exposed outwardly via the first indentation and the opening after the removal of the first mold.

2. The electrical connector as claimed in claim 1, wherein said stiffener includes a top wall shielding the upper portion of tongue portion and a pair of side walls shielding the pair of side portions of the tongue portion, each opening extending through the top wall and the side wall of the stiffener.

3. The electrical connector as claimed in claim 1, wherein said upper portion of tongue portion defines a plurality of second indentations staggered with the passageways for accommodating second molds, each of the body portions of the terminals having an upper surface and a side surface resisted against by the second mold, two adjacent terminals partly exposed outwardly via one corresponding second indentation.

4. The electrical connector as claimed in claim 1, wherein said lower portion of the tongue portion includes a plurality of ribs alternating with the plurality of passageways, said rib having a front end retreated backwardly to form a first recess accommodating a fourth mold confining the terminals.

5. The electrical connector as claimed in claim 1, wherein said tongue portion has a pair of flanges at two opposite sides of the lower portion, said plurality of passageways defined between the pair of flanges.

6. The electrical connector as claimed in claim 5, wherein said flange defines a third indentation opened downwardly and extending through the side portion of tongue portion for accommodating a third mold, said body portion of each outermost terminal having a lower surface and the side surface for being resisted against by the third mold, the lower surface and the side surface of the outermost terminal body portion exposed outwardly.

7. The electrical connector as claimed in claim 5, wherein said flange defines a fourth indentation exposing through the upper portion, the side portion, and the lower portion of the tongue portion for accommodating a fourth mold for confining the stiffener.

8. The electrical connector as claimed in claim 1, further comprising a shell and a grounding member attached to the shell, the shell including a top wall, a bottom wall, and a pair of side walls and shielding the insulative housing.

9. The electrical connector as claimed in claim 8, wherein each terminal comprises a substantially V-shaped compressible tail portion and a connecting portion connecting with the tail portion and the body portion, said tail portion disposed below the insulative housing and facing to the body portions for compression mount to a printed circuit board.

10. The electrical connector as claimed in claim 9, wherein said grounding member comprises a primary plate welded onto the bottom wall of the shell and a pair of resisting portions disposed at two opposite sides of the primary plate, each resisting portion having a configuration substantially same to that of the tail portion for being compression mount to the printed circuit board.

11. The electrical connector as claimed in claim 10, wherein each of the resisting portion and the tail portion comprises an end portion proximate to a bottom wall of the shell.

12. An electrical connector comprising:

an insulative housing including a base portion and a tongue portion extending forwardly from the base portion;

a plurality of terminals each having a contact portion, a body portion secured in the tongue portion, a substantially V-shaped compressible tail portion, and a connecting portion between the tail portion and the body portion, said tail portion disposed below the insulative housing and facing to the body portion for compression mount to a printed circuit board;

a shell including a top wall, a bottom wall and a pair of side walls and shielding the insulative housing; and

a grounding member comprising a primary plate secured to the bottom wall of the shell and a pair of resisting portions disposed at opposite sides of the primary plate, each resisting portion having a configuration substantially same to that of the tail portion for being compression mount to the printed circuit board.

13. The electrical connector as claimed in claim 12, wherein each of the resisting portion and the tail portion comprises an end portion proximate to a bottom wall of the shell.
