Abstract

A card connector includes an insulative housing, a number of contacts retained in the insulative housing, a metallic shell covering the insulative housing to jointly form a card receiving space, and a locking member pivotally mounted to the insulative housing. The locking member includes a card locking beam outside the card receiving space. The locking member is pivotable to an opening status where a card can be freely inserted into the card receiving space along a back-to-front direction, and the locking member is pivotable to a closed status where the card is restricted by the card locking beam in order to prevent the card from backwardly withdrawing from the card receiving space.

Claims

1. A card connector comprising:

a connector body comprising an insulative housing and a metallic shell covering the insulative housing to jointly form a card receiving space;

a plurality of contacts retained in the insulative housing, each contact comprising a contacting portion protruding into the card receiving space; and

a locking member pivotally mounted to the connector body, the locking member comprising a card locking beam outside the card receiving space;

wherein

the locking member is pivotable in an upward direction to an opening status where a card can be freely inserted into the card receiving space along a back-to-front direction, and the locking member is pivotable to a closed status where the card is restricted by the card locking beam in order to prevent the card from backwardly withdrawing from the card receiving space.

2. The card connector as claimed in claim 1, wherein the locking member comprises a block abutting against a top side of the connector body so as to avoid over pivoting when the locking member pivots from the opening status to the closed status.

3. The card connector as claimed in claim 1, wherein the locking member comprises a pair of side arms pivotally mounted to a pair of lateral sides of the connector body, each lateral side of the connector body defining a hole and each side arm comprising a pintle pivotally received in the hole.

4. The card connector as claimed in claim 3, wherein the insulative housing comprises a bottom wall with the contacts mounted thereon and a pair of side walls extending upwardly from opposite sides of the bottom wall, the metallic shell comprising a top cover above the bottom wall and a pair of side portions attached to the side walls, the hole comprising a first hole sidewardly extending through the side portion and a second hole defined sidewardly in the side wall.

5. The card connector as claimed in claim 3, wherein the locking member comprises a pair of first extensions extending inwardly from and perpendicular to the side arms, the insulative housing defining an inserting face through which the card receiving space extends, the pair of first extensions being located onto the inserting face when at the closed status.

6. The card connector as claimed in claim 5, wherein the locking member comprises a second extension extending backwardly from one of the first extensions and a third extension extending backwardly from the other of the first extensions, the second and the third extensions being parallel to the side arms while the third extension is shorter than the second extension.

7. The card connector as claimed in claim 6, wherein the locking member comprises an inclined portion extending from the third extension for abutting against a slant corner of the card when the locking member is under the closed status, the card locking beam bridging the third extension and the inclined portion.

8. The card connector as claimed in claim 3, wherein the locking member is substantially U-shaped and each pintle is located adjacent a distal end of the side arm.

9. A card connector comprising:

a connector body comprising an insulative housing and a metallic shell covering the insulative housing to jointly form a card receiving space;

a plurality of contacts each comprising a contacting portion protruding into the card receiving space;

a locking member pivotally mounted to the connector body, the locking member comprising a card locking beam extending backwardly beyond the card receiving space; and

an elastic member sandwiched between the locking member and the connector body;

wherein

the locking member is outwardly and horizontally pivotable to reach an opening status where a card can be freely inserted into the card receiving space along a back-to-front direction, and the locking member is then pivoted by the elastic member to reach a closed status where the card is restricted by the card locking beam in order to prevent the card from backwardly withdrawing from the card receiving space.

10. The card connector as claimed in claim 9, wherein the elastic member is compressed when the locking member is under the opening status, and the elastic member is released so as to drive the locking member from the opening status to the closed status.

11. The card connector as claimed in claim 9, wherein the insulative housing comprises a bottom wall with the contacts mounted thereon and a side wall extending upwardly and laterally from the bottom wall, the locking member comprising a side arm parallel to the side wall, the elastic member being compressed between the side arm and the side wall.

12. The card connector as claimed in claim 11, wherein the elastic member is a coiled spring, the side arm comprising a first pin for positioning one end of the coiled spring and the side wall comprising a second pin for positioning the other end of the coiled spring.

13. The card connector as claimed in claim 11, wherein the side wall defines a first hole, the locking member comprising a first block extending towards the card receiving space from the side arm, the first block comprising a first pintle pivotally received in the first hole.

14. The card connector as claimed in claim 13, wherein the side wall defines a second hole opposite to the first hole, the locking member comprising a second block extending towards the card receiving space from the side arm, the second block being opposite to the first block with the side wall sandwiched therebetween, the second block comprising a second pintle pivotally received in the second hole.

15. The card connector as claimed in claim 14, wherein the first and the second blocks extend from upper and lower edges of the side arm, respectively, and the first and the second blocks are perpendicular to the side arm.

16. The card connector as claimed in claim 11, wherein the locking member comprises an extension sidewardly extending from and perpendicular to the side arm, the card locking beam being L-shaped and extending backwardly from the extension.

17. An electrical card connector for use with an electronic card, comprising:

a body unit defining a card receiving space communicating with an exterior in a first direction via an opening;

a plurality of contacts disposed in the body unit with contacting sections extending into the card receiving cavity in second direction perpendicular to said first direction;

a locking member constantly associated with and assembled to the body unit and moveable between a full open position for fully exposing the opening to the exterior, and a full locking position for locking a rear end of the corresponding electronic card when said electronic card is received in the card receiving space and the rear end extends through the opening into the exterior.

18. The electrical card connector as claimed in claim 17, wherein the locking member is pivotally moveable relative to the housing unit with a pivotal axis extending in a third direction perpendicular to both said first direction and said second direction.

19. The electrical card connector as claimed in claim 17, wherein said housing unit includes an insulative housing and a metallic shell.

20. The electrical card connector as claimed in claim 17, wherein said locking member defines a height similar to that of the housing unit when said locking member is located at the full locking position.
