Abstract

An electrical connector assembly is used for connecting to a chip module. The electrical connector assembly includes an electrical connector and a dust-proof cover. The electrical connector includes an insulative housing, a plurality of terminals and a shell covering the insulative housing. The insulative housing includes a second cavity for receiving the chip module. The shell defines an opening corresponding to the second cavity. The dust-proof cover includes a dust-proof portion covering the opening and a pair of inclined pushing portions protruding from the dust-proof portion to the second cavity. The dust-proof cover has a plurality of supporting portions for supporting the dust-proof portion. The supporting portions separate from the shell when the inclined pushing portion is pushed by the chip module, and the dust-proof cover separates from the electrical connector.

Claims

1. A dust-proof cover used for an electrical connector comprising:

a dust-proof portion extending horizontally;

at least one inclined pushing portions disposed at one side of the dust-proof portion, the inclined pushing portion having an inclined pushing face obliquely with respect to the dust-proof portion; and

a plurality of supporting portions for supporting the dust-proof portion, wherein the inclined pushing portion is configured to be upwardly pushed by a chip module received within the electrical connector to have the dust-proof cover removed from the electrical connector;

wherein

said supporting portions are located at two opposing lateral sides of the dust-proof cover in a transverse direction and configured to transversely abut against the electrical connector and sandwich the electrical connector therebetween to guide removal of the dust-proof cover from the electrical connector.

2. The dust-proof cover as claimed in claim 1, wherein the dust-proof cover defines a first cavity disposed at one side of the inclined pushing portion, the inclined pushing portion is disposed in the first cavity.

3. The dust-proof cover as claimed in claim 1, wherein the supporting portions are disposed at two opposite sides of the dust-proof portion, the supporting portions and the inclined pushing portions extend in a same direction.

4. The dust-proof cover as claimed in claim 1, further including a pair of relatively resilient latches at a font end region and a pair of relatively rigid latches at a rear end region, wherein said inclined pushing portion is located closer to the relatively rigid latches than to the relatively resilient latches.

5. An electrical connector assembly used for connecting to a chip module, the electrical connector assembly comprising:

an electrical connector having an insulative housing, a plurality of terminals received in the insulative housing and a metallic shell covering the insulative housing, the insulative housing having a cavity for receiving the chip module, the shell defining an opening corresponding to the cavity;

a dust-proof cover attached to the shell and having a dust-proof portion covering the opening, at least one pushing portion protruding downwardly from the dust-proof portion toward the second cavity;

wherein

the dust-proof cover has a plurality of supporting portions for supporting the dust-proof portion;

wherein

when the dust-proof cover is associatively attached upon the shell to commonly approach the housing, the pushing portion is upwardly pushed by said chip module received within the housing of electrical connector so as to have the dust-proof cover separated from the shell;

wherein

said supporting portions are located on two opposing lateral sides of the dust-proof cover in a transverse direction and transversely abut against the shell of the electrical connector and sandwich the shell therebetween to guide removal of the dust-proof cover from the shell of the electrical connector.

6. The electrical connector assembly as claimed in claim 5, wherein said pushing portion is located closer to a rear end region of the dust-proof cover than to a front end region of the dust-proof cover.

7. The electrical connector assembly as claimed in claim 6, wherein the dust-proof cover includes a pair of relatively resilient latches at the front end region and a pair of relatively rigid latches at the rear end region.

8. The electrical connector assembly as claimed in claim 5, wherein the dust-proof cover defines another cavity corresponding to the opening, the pushing portions are disposed in said another cavity.

9. The electrical connector assembly as claimed in claim 5, wherein the supporting portions are disposed at two opposite sides of the dust-proof portion, the supporting portions and the pushing portion extend in a same direction.

10. The electrical connector assembly as claimed in claim 5, wherein the supporting portions are disposed at two lateral sides of the shell.

11. The electrical connector assembly as claimed in claim 5, wherein the electrical connector comprises a connecting member located one side of the insulative housing, and the shell is pivotally connected to the connecting member and rotatably covers the insulative housing.

12. The electrical connector assembly as claimed in claim 11, wherein said shell is pivotally connected to a lever, and said lever is pivotally connected to the connecting member.

13. The electrical connector assembly as claimed in claim 5, wherein said pushing portion forms an inclined pushing face extending along an oblique direction angled with a front-to-back direction.

14. The electrical connector assembly as claimed in claim 5, wherein said shell is pivotally mounted to a lever, and the lever is pivotally mounted to the connecting member.

15. An electrical connector assembly comprising:

an insulative housing defining an upward receiving cavity adapted to receive a chip module therein;

a metallic shell pivotally connected around a rear end of the housing and defining an opening aligned with the receiving cavity in a vertical direction when the shell covers said housing so as to allow said chip module to upwardly extend without interference; and

a dust-proof cover attached upon the shell and including, in a front-to-back direction perpendicular to said vertical direction, a pair of front latches around a front end region and a pair of rear latches around a rear end region to respectively engage with the shell, wherein

said dust-proof cover further includes at least a pushing portion extending downwardly toward the receiving cavity, and a plurality of supporting portions commonly sandwiching the shell therebetween in a transverse direction perpendicular to both said vertical direction and said front-to-back direction so as to assure stable removal of the dust-proof cover from the shell via confrontation between the pushing portion and the chip module.

16. The electrical connector assembly as claimed in claim 15, wherein the pushing portion is located around the rear end region.

17. The electrical connector assembly as claimed in claim 16, wherein said dust-proof cover is pivotally removed from the shell in a rotatable manner about said pushing portion.

18. The electrical connector assembly as claimed in claim 17, wherein the latches around the front end region are more resilient than the latches around the rear end region.

19. The electrical connector assembly as claimed in claim 15, wherein said pushing portion forms an inclined face extending along an oblique direction angled with the front-to-back direction.

20. The electrical connector assembly as claimed in claim 15, wherein said shell is indirectly attached to a connecting member via a lever which actuates the shell to be locked with a locking head around a front end of the housing, and said connecting member is located around the rear end of the housing.
