FASTENING DEVICE FOR CARD
A device for fastening a card on the motherboard of a computer is provided. In one embodiment, the device comprises an elongated, upright snapping assembly and a substantially U-shaped seat assembly secured thereon. Fastening a first end of the card at a connector on the motherboard, placing the second end thereof in the fastening device by pressing a latch member, positioning two risers in two slits of the second end, and releasing the latch member will cause two latch elements to exert a resilient force on the second end of the card for fastening.
1. Field of the Invention
The present invention relates to fastening devices and more particularly to an improved device for fastening a card on the motherboard of a computer.
2. Description of Related Art
Conventionally, a card is added to a computer for providing additional functions. The size of card is reduced gradually as the development of miniature electronic products. For example, a card is disposed laterally in a notebook complying with mini PCI (Peripheral Component Interconnect). That is, holes of the connector on the motherboard are disposed laterally. A card is thus disposed laterally on the motherboard after fastening at the connector. As an end, the occupied height is much reduced. Also, fastening devices are provided on the motherboard for holding the card stably in addition to the snapping coupling force of the connector exerted on the card. Unfortunately, such fastening devices suffered from several disadvantages such as complicated components, difficult installation, etc. Thus, the need for improvement still exists.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a device for fastening a card on the motherboard of a computer in an easy, simple installation procedure.
In one aspect of the present invention there is provided a device for fastening a card on a motherboard of a computer, comprising an elongated, upright snapping assembly comprising a central board, two wing plates extended from both ends of the board, two supports each extended from one end of the wing plate, two latch elements each formed on the support, two tabs each extended from a bottom of the support and being perpendicular thereto, and a latch member extended from a top of the board; and a substantially U-shaped seat assembly comprising an elongated base, two end support elements disposed perpendicular with respect to the base, two spaced resilient members each extended toward the support element and above the base for urging against the support, two upright stop plates opposite the resilient members for matingly engaging with the wing plates for supporting the seat assembly thereon, two clamping mechanisms each provided on the support element and including a raised flat member and an opposite, spaced tab member wherein the tab is adapted to insert through a gap between the flat member and the tab member to be disposed under the flat member with a lower portion of the support being clamped by the tab member, two bifurcated attachment brackets each extended downwardly from the support element to fasten on the motherboard, two walls each formed on an outer edge of the support element, and two risers each extended upright from the wall; whereby fastening a first end of the card at a connector on the motherboard, placing the second end thereof in the fastening device by pressing the latch member, positioning the risers in two slits of the second end, and releasing the latch member will cause the latch elements to exert a resilient force on the second end of the card for fastening.
In another aspect of the present invention there is provided a device for fastening a card on a motherboard of a computer, comprising an elongated, upright snapping assembly comprising a central board, two wing plates extended from both ends of the board, two supports each extended from one end of the wing plate, two latch elements each formed on the support, two tabs each extended from a bottom of the support and being perpendicular thereto, and a latch member extended from a top of the board; and a seat assembly comprising two opposite, spaced L-shaped sections each including a transverse base, a longitudinal support element, a resilient member extended toward the support element and above the base for urging against the support, an upright stop plates opposite the resilient member for matingly engaging with the wing plate for supporting the seat assembly thereon, a clamping mechanism provided on the support element and including a raised flat member and an opposite, spaced tab member wherein the tab is adapted to insert through a gap between the flat member and the tab member to be disposed under the flat member with a lower portion of the support being clamped by the tab member, a bifurcated attachment bracket extended downwardly from the support element to fasten on the motherboard, a wall formed on an outer edge of the support element, and a riser extended upright from the wall; whereby fastening a first end of the card at a connector on the motherboard, placing the second end thereof in the fastening device by pressing the latch member, positioning the risers in two slits of the second end, and releasing the latch member will cause the latch elements to exert a resilient force on the second end of the card for fastening.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS

A clamping mechanism 25 is provided on each support element 22. The clamping mechanism 25 comprises a raised flat member 251 and an opposite tab member 252. The flat member 251 is adapted to dispose on the tab 16. The tab member 252 is slanted upwardly and is flexible. The flat member 251 and the tab member 252 are spaced by a gap so that the tab 16 can be inserted to be disposed under the flat member 251. As shown in
Under the support element 22 there is provided a bifurcated attachment bracket 213 extended downwardly. One of a plurality of holes 32 on the motherboard 30 is adapted to receive and fasten the attachment bracket 213 therein so as to secure the fastening device onto the motherboard 30. On the support element 22 there are provided a hole 214 so that a fastener (e.g., screw or bolt) can be driven thereinto for securing the support element 22 on the motherboard 30, and a wall 215 bent about 90 degrees about the support element 22, the wall 215 having a top riser 216 adapted to snugly insert into an elongate slit 43 at the second end 42 of the card 40 when the second end 42 is fastened by the latch element 15. As an end, the card 40 is secured onto the wall 215.

To the contrary, a user may press the latch member 17 as indicated by the left arrow X or counterclockwise pivot the latch elements 15 prior to pulling the second end 42 out of the fastening device. Next, remove the first end 41 from the connector 31. This finishes the disassembly of the card 40 from the motherboard 30.
