1. Field of the Invention
The present invention relates to an ejector for a motherboard, and particularly to an ejector which can readily eject a motherboard from a chassis without damaging the motherboard.
2. Description of the Prior Art
Generally, a personal computer or a server has limited inner space, therefore a printed circuit board is usually horizontally connected with a connecter. An example is disclosed in China Patent No. 02247527.3. A memory of this patent is horizontally connected with a connector of a motherboard. The connector includes an elongated main body and two locking portions secured to opposite sides of the main body. The memory is inserted to the connector and secured by the locking portions. The locking portions must be pulled outwardly, then the memory is manually taken out. This manner is suitable for a small printed circuit board connected to a connector. However, when disengaging a large printed circuit board such as a motherboard from a connector, pulling out the locking portions is a tough work in a narrow inner space of the personal computer or server. Furthermore, pulling out the motherboard with manual work can not guarantee the pulling force being parallel to the motherboard. Therefore, the motherboard and the connecter are prone to be damaged.
Thus, an improved ejector for ejecting a motherboard from a chassis is desired.
Accordingly, an object of the present invention is to provide an ejector for rapidly ejecting a printed circuit board from a connector of a computer chassis.
A further object of the present invention is to provide an ejector for smoothly disengaging a printed circuit board from a connector of a computer chassis without damaging the printed circuit board and the connector.
To achieve the above-mentioned objects, an ejection assembly in accordance with a preferred embodiment of the present invention is used for rapidly ejecting a motherboard from a server chassis. The ejection assembly includes a tray for supporting the motherboard, and an ejector. A connector is disposed in the chassis. The ejector is pivotally mounted to the tray, and includes an ejecting portion to abut against a front edge of a bottom plate of the chassis when the motherboard is electronically connected to the connector of the chassis. The ejector is pivoted outwardly so that the ejecting portion presses the front edge of the bottom plate to draw the tray outwardly, the motherboard is thereby horizontally and rapidly ejected from the connector of the chassis without damaging the connector and the motherboard.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of preferred embodiments of the present invention with the attached drawings, in which:
Referring to
The motherboard 10 has a horizontal connecting portion 12 at a rear end thereof. The chassis 20 comprises a bottom plate 24, a left side plate 25, and a right side plate 26. An elongated board 27 is mounted to an inner surface of the left side plate 25. A plurality of bent tabs 271 is stamped inwardly from the elongated board 27. A blocking tab 273 is bent inwardly from a front portion of the elongated board 27 with a threaded hole 274 defined therein. A connector slot 22 is disposed in the chassis 20 corresponding to the connecting portion 12 of the motherboard 10. A partition plate 28 is mounted on the bottom plate 24 of the chassis 20 in the vicinity and parallel to the right side plate 26. The partition plate 28 comprises a mounting portion 282 and an upright portion 281 extending upright from the mounting portion 282. A plurality of bent tabs 283 is stamped inwardly from the upright portion 281.
The motherboard tray 30 is used for supporting the motherboard 10, and comprises a left guiding plate 31 and a right guiding plate 32 at opposite sides thereof. The left and right guiding plate 31, 32 corporate with the bent tabs 271, 283 to guide the tray 30 into the chassis 20 and restrict the tray 30 in a vertical direction and a left-to-right direction. A front plate 33 is formed at a front portion of the tray 30. The front plate 33 has a thumb-screw 60 mounted thereto and defines a plurality of openings 34 for accommodating frontal connectors of the motherboard 10. A horizontal locking tab 36 is formed outwardly from the front plate 33. A threaded aperture 38 is defined in the locking tab 36. The ejector 40 comprises a locking portion 46 having an arc profile, a handle portion 44 which is bent upwardly to form a U-shaped cross section, and an ejection portion 48 forming an ejection tab 49 downwardly. A pivot hole 47 is defined in the locking portion 46. A screw 50 extends through the pivot hole 47 of the ejector 40 and then engages in the threaded aperture 38 of the locking tab 36, the ejector 40 is thereby pivotally secured to the locking tab 36.
