Abstract

A socket connector includes an insulative base ( 2 ), a plurality of contacts ( 3 ) therein with an engaging portion ( 32 ) and a floating cover ( 5 ). The floating cover ( 5 ) includes a plurality of through holes ( 53 ) for receiving the engaging portions ( 32 ) extending therethrough. The socket connector includes a metallic shell ( 4 ) having a plurality of receiving holes ( 41 ) for receiving the contacts therein and electrically engaging with a metallic surface ( 52 ) formed on bottom of the floating cover ( 5 ).

First claim

What is claimed is:

1. A socket connector comprising:
an insulative base comprising a plurality of passageways receiving a plurality of contacts therein and the contacts having engaging portions at end portions thereof;
a floating cover movably mounted above the insulative base and comprising a plurality of through holes for receiving the engaging portions of the contacts extending therethrough; and
wherein the socket connector comprises a metallic shell retained in the insulative base, the metallic shell comprises a plurality of receiving holes to receive the contacts therein and electrically engages with a metallic layer formed on bottom of the floating cover;
wherein the metallic shell comprises a plurality of protruding portions engaging with the metallic layer.
wherein the floating cover comprises an upper insulative layer which prevents the metallic layer from short circuit and the upper insulative layer extends into the through holes; and
wherein the floating cover comprises a metallic grounding portion being formed on bottom side of the metallic layer and always engaging with at least one of the contacts, thereby building another grounding path between the metallic layer and the at least one of the contacts for preventing crosstalk.

2. The socket connector as described in claim 1 , wherein the metallic grounding portion is formed by a solder ball adhering to the metallic surface.

3. The socket connector as described in claim 1 , wherein the floating cover is moved between a first position in which the cover disengages with the metallic shell and the contacts protrudes out of the cover and a second position in which the contact are pressed downwardly and deformed so that the engaging portion moves approximately along a track of curve, until the cover engages with the metallic shell.

4. A socket connector comprising:
an insulative base comprising a plurality of passageways receiving a plurality of contacts therein and the contacts having engaging portions at end portions thereof for electrically connecting with a CPU; and
a cover movably mounted above the insulative base and comprising a plurality of through holes for receiving the engaging portions of the contacts extending therethrough;
wherein the cover comprises an upper insulative surface and a metallic surface located on bottom side of the insulative surface and electrically engaging with the selected contacts;
wherein said cover is moving up and down floatable.
wherein the cover comprises a metallic grounding portion being formed on bottom side of the metallic surface and always engaging with at least one of the contacts, thereby building a grounding path between the metallic surface and the least one grounding contact for preventing crosstalk,
wherein the insulative surface is provided by an insulative plate or an insulative coating layer,
wherein the metallic surface is provided by a metallic plate or a metallic coating layer for electrically connecting with a metallic shell retained in the insulative base.

5. The socket connector as described in claim 4 , wherein the metallic grounding portion is formed by a solder ball adhering to the metallic surface.

6. The socket connector as described in claim 4 , wherein the upper insulative surface prevents the metallic surface from short circuit and extends into the through holes.

7. A socket connector for use with an electronic package, comprising:
a metallic shield structure defining a grid like cross-sectional configuration in a top view;
a terminal module assembly secured to the shield structure and including a plurality of contacts associated therewith, each of said contacts including an upper mating section and a lower mounting section in a vertical direction, said contacts being categorized with grounding contacts and signal contacts;
a horizontal upper cover plate mounted above the shield structure and defining a plurality of through holes through which the upper mating sections of the contacts extend upwardly;
wherein the upper cover plate includes an insulative structure on an upper side thereof for not improperly electrically connecting to the electronic package which is adapted to be mounted upon the cover plate, and a metallic structure on a bottom side thereof for mechanically and electrically connecting the shield structure;
wherein said metallic structure further mechanically and electrically connects to the corresponding grounding contacts;
wherein said cover plate is moveable in said vertical direction;
the socket connector further including a horizontal bottom cover plate located below the shield structure, wherein said horizontal bottom cover plate defines a plurality of recesses to receive corresponding solder balls which are soldered to the lower mounting sections of the corresponding contacts, respectively, and said horizontal bottom cover plate includes an embedded metallic shield layer mechanically and electrically connecting the shield structure.

8. The socket connector as claimed in claim 7 , wherein said terminal module assembly includes a plurality of terminal modules each defining an insulator extending along a first direction, in said top view, with the associated contacts therein.

9. The socket connector as claimed in claim 8 , wherein the upper mating section extends in a second direction, in said top view, angled with said first direction.

10. The socket connector as claimed in claim 7 , wherein each of said through hole is coated with insulative material on interior surfaces.
