Abstract

A card edge connector includes an elongated insulative housing extending along a left-to-right direction, a plurality of conductive terminals retained in the insulative housing and an ejector retained at one end of the insulative housing. The insulative housing defines a central slot recessed from an upper surface thereof for receiving a memory module. The ejector defines a base portion and a pair of gripping portions extending upwardly from the base portion, two gripping portions have an accommodating slot located therebetween for receiving the memory module and a lump portion located in the accommodating slot. The lump portion defines an elastic arm projecting into the accommodating slot for locking the memory module, When the memory module is pulled out in a hard-interference manner, the memory module will press upwardly against the elastic arm so that the elastic arm is elastically deformed to release the memory module.

First claim

What is claimed is:

1. A card edge connector, comprising:
an elongated insulative housing extending along a left-to-right direction and defining a central slot recessed from an upper surface thereof for receiving a memory module;
a plurality of conductive terminals retained in the insulative housing; and
an ejector retained at one end of the insulative housing and defining a base portion and a pair of gripping portions extending upwardly from the base portion and defining an accommodating slot located therebetween and running through the ejector in the left-to-right direction for receiving the memory module and a lump portion located in the accommodating slot for locking within a notch of the memory module; wherein
the lump portion defines an elastic arm projecting into the accommodating slot for locking the memory module, and when the memory module is pulled out in a hard-interference manner, the memory module will press upwardly against the elastic arm so that the elastic arm is elastically deformed to activate outward rotation of the ejector to release the memory module.

2. The card edge connector as described in claim 1 , wherein the accommodating slot further includes a first accommodating slot located above the lump portion and running through a top surface of the ejector and a second accommodating slot located below the lump portion for receiving a bottom edge of the memory module.

3. The card edge connector as described in claim 1 , wherein the insulative housing defines an attaching portion extending outside from an end wall of the insulative housing, the attaching portion defines a pair of opposite side walls and an attaching space formed between the side walls, the ejector defines an ejecting portion extending inwardly to the attaching space from a lower end of the base portion for ejecting the memory module.

4. The card edge connector as described in claim 3 , wherein the ejector defines a pair of extending portions extending toward the attaching portion from both sides of the base portion, each extending portions defines a protruding portion located at the front thereof and extending inwardly thereof and the attaching portion defines a pair of retaining slots located at two side walls thereof and latched with the corresponding protruding portions.

5. The card edge connector as described in claim 1 , wherein the lump portion defines a connecting portion integrally connecting with two gripping portions, and the elastic arm is extending integrally from the connecting portion and transversely unconnected with the two gripping portions in order to be elastic.

6. The card edge connector as described in claim 5 , wherein the connecting portion defines a lower surface, and an oblique surface connecting the lower surface and locating at an inner side of the lower surface for the memory module being pulled out easily, and the elastic arm extends downwardly and horizontally toward the central slot from the lower surface of the connecting portion.

7. The card edge connector as described in claim 6 , wherein the elastic arm latches into a cutout of the memory module and abuts against a locking surface of the memory module in a surface contact manner.

8. The card edge connector as described in claim 6 , wherein the angle formed between the oblique surface and the elastic arm is less than 90 degrees.

9. An ejector adapted for being equipped with a card edge connector to lock a memory module inserted into the card edge connector, comprising:
a base portion; and
a pair of gripping portions extending upwardly from the base portion an accommodating slot located between said two gripping portions and separating said two gripping portions from each other for receiving the memory module and
a pair of lump portions integrally protruding from said corresponding gripping portions and into said accommodating slot for locking the memory module; wherein
the lump portions are isolated from one another by an opening so that the lump portions could be resiliently splayed away from each other under a condition that the memory module is removed out from the card edge connector directly in a hard-interference manner;
an ejector pivotally mounted to one end of the housing in said longitudinal direction, said ejector including a base portion, an ejecting portion located below the base portion and extending into the central slot for ejecting the module, and a latch device located above the ejecting portion and aligned with the central slot along the longitudinal direction for locking in a notch of the memory module when said memory module is received within the central slot.

10. The ejector as described in claim 9 , wherein the lump portion defines a connecting portion integrally connecting with two gripping portions, and the elastic arm is extending integrally from the connecting portion and unconnected with the two gripping portions in order to be elastic.

11. The ejector as described in claim 10 , wherein the defines a lower surface, and an oblique surface connecting the lower surface and locating at an inner side of the lower surface for the memory module being pulled out easily, and the elastic arm extends downwardly and horizontally toward the central slot from the lower surface of the connecting portion.

12. The ejector as described in claim 11 , wherein the angle formed between the oblique surface and the elastic arm is less than 90 degrees.

13. An electrical connector for use with a memory module, comprising:
an insulative housing having a central slot extending along a longitudinal direction and upwardly open to an exterior in a vertical direction perpendicular to said longitudinal direction for receiving said memory module therein;
a plurality of contacts disposed in the housing beside said central slot in a transverse direction perpendicular to both said longitudinal direction and said vertical direction; and
an ejector pivotally mounted to one end of the housing in said longitudinal direction, said ejector including a base portion, an ejecting portion located below the base portion and extending into the central slot for ejecting the module, and a lump portion having an elastic arm located above the ejecting portion for downwardly confronting a locking surface in a notch of the memory module when said memory module is received within the central slot; wherein the elastic arm is upwardly deformable for complying with a harsh forcible upward movement of the memory module to activate an outward rotation of the ejector for releasing the memory module from the connector.

14. The electrical connector as claimed in claim 13 , wherein said elastic arm extends in a cantilevered manner with an outer root section and an inner free end along the longitudinal direction.

15. The electrical connector as claimed in claim 13 , wherein said lump portion is unitarily formed with the ejector.

16. The electrical connector as claimed in claim 13 , wherein a pivotal shaft of the ejector is located at a same level with the ejecting portion, and the elastic arm is located at an outer side of the pivotal shaft with a distance along said longitudinal direction in a top view.

17. The electrical connector as claimed in claim 13 , wherein said ejector includes a pair of gripping portions communing defining an accommodating slot therebetween for receiving the memory module therein, and the lump portion is located in said accommodating slot.

18. The electrical connector as claimed in claim 17 , wherein each of said pair of gripping portions provides an upward outwardly extending wing like region for fi
