Abstract

An audio jack connector ( 100 ) includes an insulative housing ( 1 ) having a number of passageways ( 111 ) and a number of slits ( 112 ) beside the passageways, and a number of contacts ( 2 ) retained in the passageways. Each contact includes a retaining portion ( 22 ) retained in the passageway, a contacting portion ( 21 ) extending inwardly from the retaining portion, and a horizontal portion ( 23 ) bent outwardly from the retaining portion and being located in a bottom face ( 11 ) of the insulative housing. The audio jack connector includes a glue plate ( 3 ) assembled to the bottom face of the insulative housing. The audio jack connector includes a glue frame ( 4 ) having a base portion ( 41 ) seamlessly sandwiched between the glue plate and the insulative housing, and a number of protrusions ( 42 ) seamlessly sandwiched between the horizontal portions of contacts and the insulative housing. The protrusions are received in the slits.

First claim

What is claimed is:

1. An audio jack connector comprising:
an insulative housing having a plurality of passageways and a plurality of slits beside the passageways, the insulative housing having a bottom face, a top face opposite to the bottom face, a mating face, a rear face opposite to the mating face, and a pair of lateral faces to define a receiving space, a mating direction along which an audio plug connector is inserted into the receiving space, a vertical direction perpendicular to the mating direction, and a transverse direction perpendicular to both the mating direction and the vertical direction;
a plurality of contacts each contact comprising a retaining portion retained in a corresponding passageway, a contacting portion extending inwardly from the retaining portion into the receiving space, and a horizontal portion bent outwardly from the retaining portion and located at the bottom face of the insulative housing;
a glue plate assembled to the bottom face of the insulative housing; and
a glue frame having a base portion seamlessly sandwiched between the glue plate and the insulative housing and a plurality of protrusions seamlessly sandwiched between the horizontal portions of contacts and the insulative housing;
wherein the protrusions are received in the slits; wherein
each protrusion comprises a pair of vertical beams sandwiched between the horizontal portion of the contact and the bottom face of the insulative housing along the mating direction: wherein
each protrusion comprises a lengthwise beam connecting between the vertical beams along the mating direction and sandwiched between the horizontal portion of the contact and the bottom face of the insulative housing along the vertical direction; wherein
the lengthwise beam is connected to the base portion via the vertical beams.

2. The audio jack connector as claimed in claim 1 , wherein the bottom face is recessed at a middle thereof to form a peripheral circular rib and the base portion is sandwiched between the glue plate and the peripheral circular rib along both the mating direction and the transverse direction.

3. The audio jack connector as claimed in claim 1 , wherein each contact comprises a securing portion bent vertically and upwardly from the horizontal portion to expose out of the insulative housing.

4. The audio jack connector as claimed in claim 3 , wherein both the retaining portion and the securing portion extend along the vertical direction, and the horizontal portion extends along the transverse direction.

5. The audio jack connector as claimed in claim 4 , wherein the slit is located between the retaining portion and the securing portion along the transverse direction and above the horizontal portion along the vertical direction after the contact is assembled in the insulative housing.

6. An electrical connector comprising:
an insulative housing defining a mating cavity communicating with an exterior along an axial direction, a plurality of passageways extending from a bottom face of the housing along a vertical direction perpendicular to said axial direction and communicating with the mating cavity;
a plurality of contacts upwardly assembled, from the bottom face, into the corresponding passageways, respectively, each of said contacts including a resilient contacting section extending into the mating cavity, and a horizontal connecting arm section extending outwardly beyond a corresponding side face of the housing; and
a glue frame surrounding a periphery of the bottom face; wherein
said glue frame is further equipped unitarily with a plurality of upward protrusions each surrounding the connecting arm section of the corresponding contact.

7. The electrical connector as claimed in claim 6 , wherein the housing further includes a downward peripheral rib which the glue frame outwardly abuts against.

8. The electrical connector as claimed in claim 7 , further including a sealing plate on the bottom face to cover the corresponding passageways, wherein said glue frame is snugly transversely sandwiched between the sealing plate and the peripheral rib.

9. The electrical connector as claimed in claim 8 , wherein the sealing plate is lower than the connecting arm sections of the contacts in the vertical direction and upwardly abuts against a bottom face of the connecting arm section of each of the contacts.

10. The electrical connector as claimed in claim 7 , wherein the bottom face of the housing further forms a plurality of upward recessed recess hidden behind the corresponding side face and adjacent to said peripheral rib to receive the corresponding upward protrusions of the glue frame, respectively.

11. The electrical connector as claimed in claim 7 , wherein said peripheral rib forms a plurality of cutouts to receive the connecting arm sections of the corresponding contacts, respectively, for preventing the connecting arm sections from moving along the axial direction.

12. The electrical connector as claimed in claim 7 , wherein a bottom surface of the periphery rib is lower than that of the connecting arm section of the contact.

13. The electrical connector as claimed in claim 6 , wherein said glue frame extends in a horizontal plane while each of said upward protrusions extends in a vertical plane perpendicular to said horizontal plane.

14. The electrical connector as claimed in claim 13 , wherein the glue frame extends in a first level while each of said upward protrusions extends in a second level higher than the first level.

15. An electrical connector comprising:
an insulative housing defining a mating cavity communicating with an exterior along front-to-back direction, a plurality of passageways extending from a bottom face of the housing along a vertical direction perpendicular to said axial direction and communicating with the mating cavity;
a plurality of contacts upwardly assembled into the corresponding passageways, respectively, each of said contacts including a resilient contacting section extending into the mating cavity, and a horizontal connecting arm section extending outwardly beyond a corresponding side face of the housing;
a plurality of cutouts formed in a peripheral region of the bottom face to receive the horizontal connecting arm sections, respectively;
a plurality of slits upward recessed in the housing intimately behind the corresponding cutouts, respectively; and
a plurality of glue protrusions filled within the corresponding slits, respectively, so as to seal at least an upper face and two opposite lateral faces of each of the horizontal connecting arm sections; further including a glue frame extending along the peripheral region to integrate said glue protrusions together.

16. The electrical connector as claimed in claim 15 , wherein the housing forms a peripheral rib surrounds said glue frame.

17. The electrical connector as claimed in claim 15 , wherein a sealing plate is attached upon a bottom face of the housing to cover the passageways, and said glue frame snugly and intimately surrounds said sealing plate.

18. The electrical connector as claimed in claim 17 , wherein both said sealing plate and said glue frame are located lower than the horizontal contacting arm sections of the contacts, in the vertical direction.

19. The electrical connector as claimed in claim 15 , wherein said glue frame further seals a bottom face of the connecting arm section of each of said contacts.

20. The electrical connector as claimed in claim 15 , wherein said glue frame extends in a horizontal plane at a first lev
