CHIP CARD RETAINING MECHANISM

Abstract

A chip card retaining mechanism for detachably retaining a chip card (50) and allowing the chip card to be connected to terminals (20) formed on a printed circuit board (60). The chip card retaining mechanism includes a base (10), two locking members (30). The base has a first surface (11) for exposing the terminals. The locking members are arranged at lateral sides of the base. Each locking member has a top plate (32) configured for limiting movement of the chip card along a horizontal direction. Each locking member further includes a stopper (324) formed at one end thereof and disposed at a movement path of the chip card in a horizontal direction. The base, and the locking members cooperatively define a receiving space for receiving the chip card therein.

Claims

1. A chip card retaining mechanism for retaining a chip card comprising: a base;terminals, the terminals retained in the base, the terminals having elastic contacts protruding from a first surface of the base for elastically abutting the chip card;a resisting member, the resisting member attached to a first end of the base; andtwo locking members, the locking members attached to lateral sides of the base, each locking member having a first top plate extending over a top of the base, each locking member further comprising a stopper formed at one end of the first top plate for abutting the chip card, the base, the locking members and the resisting member cooperatively defining a receiving space for receiving the chip card therein.

2. The chip card retaining mechanism as claimed in claim 1, wherein each locking member includes at least one latches, and the base has at least one latch slots adjacent to at least one sides thereof, the resisting member being attached to the base by means of the latches engaging in the latch slots.

3. The chip card retaining mechanism as claimed in claim 2, wherein each locking member further includes a first bottom plate and a first side plate, the latches extending from the first bottom plate.

4. The chip card retaining mechanism as claimed in claim 3, wherein the first top plate extends from the first side plate and faces the first bottom plate, and the first top plate is configured for limiting movement of the chip card along a vertical direction.

5. The chip card retaining mechanism as claimed in claim 1, wherein each locking member is formed integrally with the base.

6. The chip card retaining mechanism as claimed in claim 1, wherein the resisting member includes a latch portion, and the base has an inserting slot adjacent to the first end thereof, the resisting member attached to the base by means of the latching portion engaging in the inserting slot.

7. The chip card retaining mechanism as claimed in claim 1, wherein the resisting member includes a second bottom plate and a second side plate, the latching portion extending from the second bottom plate.

8. The chip card retaining mechanism as claimed in claim 7, wherein the resisting member further includes a second top plate facing the second bottom plate, and the second top plate configured for limiting movement of the chip card along a vertical direction.

9. The chip card retaining mechanism as claimed in claim 1, wherein the resisting member is integrally formed with the base.

10. A chip card retaining mechanism for detachably retaining a chip card and allowing the chip card to be connected to terminals formed on a printed circuit board, the chip card retaining mechanism comprising: a base, the base having a first surface for exposing the terminals; andtwo locking members, the locking members arranged at lateral sides of the base, each locking member having a first top plate configured for limiting movement of the chip card along a vertical direction, each locking member further comprising a stopper formed at one end thereof and disposed at a movement path of the chip card along a horizontal direction, the base, and the locking members cooperatively defining a receiving space for receiving the chip card therein.

11. The chip card retaining mechanism as claimed in claim 10, wherein each locking member includes at least one latches, and the base has at least one latch slots adjacent to at least one sides thereof, the resisting member attached to the base by means of the latches engaging in the latch slots.

12. The chip card retaining mechanism as claimed in claim 11, wherein each locking member further includes a first bottom plate and a first side plate, the latches extending from the first bottom plate.

13. The chip card retaining mechanism as claimed in claim 12, wherein the first top plate extends from the first side plate and faces the bottom plate.

14. The chip card retaining mechanism as claimed in claim 10, further comprising a resisting member attached at a first end of the base.

15. The chip card retaining mechanism as claimed in claim 14, wherein the resisting member comprises a second side plate and a second top plate extending from the second side plate, the second side plate adhered to an end wall of the base.

16. The chip card retaining mechanism as claimed in claim 15, wherein the resisting member comprises a second bottom plate opposite to the second top plate, the second bottom plate having a latching portion extending therefrom, and the base has an inserting slot, the latching portion being engagable in the inserting slot.
