ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an ejector device, more particularly to an ejector device for a mobile module.
2. Description of the Related Art
A mobile module (MMO) used in notebook computers includes a circuit board, a central processing unit (CPU) mounted on one side of the circuit board, and a plurality of module terminals mounted on the other side of the circuit board proximate to one edge of the latter. The module terminals are inserted into corresponding board terminals on a main board to establish electrical connection between the mobile module and the main board.
During testing of a main board that incorporates several mobile modules, there is a need for repeated replacement of the mobile modules. Currently, replacement is performed via manual removal of the mobile modules, which can result in damage to the module terminals due to uneven application of forces. It has been proposed heretofore to use dedicated equipment for removing mobile modules from main boards to alleviate the drawback of damage to the module terminals. However, since mobile modules typically have different size specifications, manufacturers need corresponding equipment with different specifications, thereby resulting in increased production costs. Moreover, when consumers upgrade their computers, no device is available to aid them in the removal of the mobile modules from the main boards. As such, consumers usually remove the mobile modules by hand during replacement, thereby arising in the aforesaid drawback of damage to the module terminals.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide an ejector device adapted to be installed on a main board to facilitate removal of a mobile module by both manufacturers and consumers regardless of the size specification of the mobile module without causing any damage to the module terminals.
Accordingly, the ejector device of this invention is adapted for removing a mobile module from a main board. The mobile module includes a circuit board, a processing unit mounted on one side of the circuit board, and a set of module terminals mounted on the other side of the circuit board opposite to the processing unit. The module terminals are disposed proximate to one edge of the circuit board, and are inserted removably into the main board for establishing electrical connection between the mobile module and the main board. The ejector device comprises a support frame and a lever. The support frame is adapted to be secured on the main board so as to extend in a direction transverse to a plane of the main board, and is adapted to be disposed adjacent to said one edge of the circuit board. The lever includes an ejecting plate portion that is adapted to be disposed between the main board and the circuit board of the mobile module, a connecting plate portion, and an operating plate portion. The connecting plate portion extends from the ejecting plate portion, and is adapted to be disposed between the support frame and said one edge of the circuit board. The connecting plate portion is mounted pivotally on the support frame about an axis parallel to the plane of the main board. The operating plate portion extends from the connecting plate portion, and is operable to cause the connecting plate portion to pivot relative to the support frame and enable the ejecting plate portion to push the circuit board of the mobile module away from the main board for removing the module terminals of the mobile module from the main board.
