Abstract

An electrical connector for electrically connecting a CPU with a PCB includes a frame, a plurality of base units assembled onto the frame and a plurality of contacts retained in the base units. The base units extend in a longitudinal direction and are assembled side by side in a transverse direction substantially perpendicular to the longitudinal direction. Each of the base units includes an insulating housing and a shielding member embedded within the insulating housing. The shielding member includes a first portion extending in the longitudinal direction and multiple second portions extending in a direction intersecting with the longitudinal direction, the second portions together with the first portion define multiple chambers. The contacts are located in the chambers defined by the shielding member.

Claims

1. An electrical connector for electrically connecting a central processing unit to a printed circuit board, comprising:

a frame defining a cavity;

a plurality of base units assembled into the cavity of the frame, the base units extending in a longitudinal direction and arranged side by side in a transverse direction substantially perpendicular to the longitudinal direction, each of the base units comprising an insulating housing and a shielding member embedded within the insulating housing, the shielding member comprising a first portion extending in the longitudinal direction and multiple second portions substantially parallel to each other and extending in a direction intersecting with the longitudinal direction, the second portions together with the first portion defining multiple chambers; and

a plurality of contacts retained in the base units and located in the chambers defined by the shielding member.

2. The electrical connector as claimed in claim 1, wherein each base unit retains one row of contacts, the contacts retained in a corresponding base unit are offset from the contacts retained in the adjacent base unit.

3. The electrical connector as claimed in claim 2, wherein the frame comprises two ends opposite to each other and two side walls opposite to each other connecting said two ends, and wherein said two side walls alternately comprises a plurality of recesses facing towards the cavity for receiving the base units.

4. The electrical connector as claimed in claim 1, wherein the second portion of the shielding member extends in the transverse direction perpendicular to the longitudinal direction.

5. The electrical connector as claimed in claim 1, wherein the second portion is assembled onto the first portion.

6. The electrical connector as claimed in claim 5, wherein the first portion comprises a plurality of first slots substantially parallel to each other in the longitudinal direction, the second portion matches with the first slots to assemble thereon.

7. The electrical connector as claimed in claim 1, wherein the second portion is bent from the first portion integrally.

8. The electrical connector as claimed in claim 1, wherein the second portion comprises a retaining portion, the retaining portion engages with the insulating housing of the adjacent base unit.

9. The electrical connector as claimed in claim 8, wherein the first portion comprises a plurality of third slots corresponding to the retaining portions of the adjacent base unit for matching with each other.

10. The electrical connector as claimed in claim 1, wherein each of the second portions comprises a cutout, multiple cutouts are arranged in a row forming a passageway communicating the multiple chambers.

11. An electrical connector for connecting an electronic component, comprising:

a plurality of base units discrete from each other and assembled together to form an area for supporting the electronic component, each of the base units comprising an insulating housing and a shielding member embedded within the insulating housing, the shielding member comprising a first portion and a plurality of second portions coupled to the first portion to form a plurality of chambers, the shielding member of a corresponding base unit disengages from the shielding member of other base units before the base units being assembled together; and

at least one contact comprising a retaining portion retained in the base unit, a width of the retaining portion is less than the distance of two adjacent second portions.

12. The electrical connector as claimed in claim 11, wherein the second portion of the shielding member in a corresponding base unit is offset from the second portion of another shielding member in the adjacent base unit.

13. The electrical connector as claimed in claim 11, wherein the second portion comprises a retaining portion, the retaining portion engages with the insulating housing of the adjacent base unit after the base units are assembled together.

14. The electrical connector as claimed in claim 11, wherein a plurality of second portions comprises a plurality of cutouts arranged in a row forming a passageway communicating the multiple chambers.

15. An electrical connector assembly comprising:

at least one unit including;

a metallic shielding member defined by at least a first portion extending in a longitudinal direction and a plurality of second portions extending in a transverse direction perpendicular to said longitudinal direction in a securely intersectional manner so as to form a plurality of corresponding chambers communicating with an exterior in a vertical direction perpendicular to both said longitudinal direction and said transverse direction; and

an insulative housing associatively coated, via an insert molding process, upon said shielding member so as to hide said shielding member horizontally;

wherein

said housing forms plurality of passageways in the corresponding chambers, respectively, and a plurality of contacts disposed in the corresponding passageways, respectively;

wherein

each of said contacts defines an upper contacting section upwardly obliquely extending above a top face of the housing.

16. The electrical connector assembly as claimed in claim 15, wherein there are a plurality shielding members stacked with one another along the transverse direction with the associated housings and contacts so as to form a matrix type arrangement wholly.

17. The electrical connector assembly as claimed in claim 16, wherein the chambers are essentially completely surrounded by the shielding member.

18. The electrical connector assembly as claimed in claim 16, wherein the chambers are offset from those in a neighboring shielding member in the transverse direction.

19. The electrical connector assembly as claimed in claim 16, wherein the second portions are unitarily formed with the first portion.

20. The electrical connector assembly as claimed in claim 16, further including a frame defining a cavity in which said plurality of shielding members with the associated housings and contacts are embedded.
