## Background
FIELD OF THE INVENTION
The present invention relates to optical disc drives, and more particularly, to an optical disc drive easy to be assembled to or disassembled from a casing of an electronic device without the need of an additional frame.
BACKGROUND OF THE INVENTION
Computer-related electronic devices have been increasingly developed along with the progress of information technology and played an important role in human life. The electronic devices are required to provide various functions and have low fabrication costs in response to the competitive nature of the market.
Therefore, during fabrication of the electronic devices, not only maintenance of satisfactory product quality and manufacturing speed but also reduction in fabrication costs should all be considered. Particularly, each stage in the production line, such as the assembly speed of an optical disc drive to a casing of an electronic device, may affect the overall manufacturing progress.
Conventionally, an optical disc drive is assembled to a computer by using a tray and a plurality of screws. Referring to FIG. 1, during assembling the optical disc drive to the computer, the optical disc drive 10 is mounted to a tray 12 by a plurality of screws (not shown), and then the tray 12 is fixed to a casing of the computer by means of a fixing structure 120 disposed at a side of the tray 12. In general, the casing of the computer must be provided with a concave portion for being engaged with the fixing structure 120 of the tray 12. When the optical disc drive 10 needs to be repaired or replaced due to malfunction thereof, the casing of the computer, the tray 12 and the optical disc drive 10 should all be disassembled in order by unscrewing the plurality of screws, thereby wasting much time and labor. Accordingly, the conventional arrangement of using the tray 12 to fasten the optical disc drive 10 to the computer undesirably requires a complex assembling/disassembling process and is cost-ineffective to implement due to the need of additionally providing the tray 12 with the fixing structure 120.
To overcome the above drawback of complexity in assembly or disassembly of the optical disc drive, Taiwanese Patent No. 570265 has disclosed an optical disc drive easy to be assembled and disassembled to and from a computer. Referring to FIGS. 2 and 3, the optical disc drive 20 is assembled to a casing 3 of the computer by an engaging component 22. The engaging component 22 has an engaging portion 220 formed at a bottom side thereof. When the engaging component 22 is fastened to the optical disc drive 20 by screws 24, the engaging portion 220 of the engaging component 22 can be engaged with another engaging portion 30 disposed on the casing 3 of the computer, thereby fixing the optical disc drive 20 to the casing 3 of the computer. On the other hand, the engaging portion 220 of the engaging component 22 can be separated from the engaging portion 30 of the casing 3 of the computer by pressing the engaging portion 220, such that the optical disc drive 20 is detached from the casing 3 of the computer.
However, the above arrangement requires the additional engaging component 22 for the optical disc drive 20 and the corresponding engaging portion 30 on the casing 3 of the computer to assemble the optical disc drive to the casing of the computer, thereby complicating the fabrication processes and increasing the fabrication costs.
A general optical disc drive comprises a main body, an insulation plate, a transfer board and screws. It is therefore desired to provide an improved optical disc drive with structural modifications of the inherent components thereof so as to allow the optical disc drive to be easily assembled to and disassembled from an electronic device, without using additionally components, thereby reducing the fabrication costs thereof.
SUMMARY OF THE INVENTION
In light of the above drawbacks in the prior art, an objective of the present invention is to provide an optical disc drive, which is easy to be assembled to and disassembled from a casing of an electronic device.
Another objective of the present invention is to provide a low-cost optical disc drive.
Still another objective of the present invention is to provide an optical disc drive, which can be assembled to a casing of an electronic device without the need of any additional frame and any tool.
A further objective of the present invention is to provide an optical disc drive, which can enhance a fixing effect of a rear plate of a casing of an electronic device.
To achieve the above and other objectives, the present invention proposes an optical disc drive to be mounted in a predetermined slot of a casing of an electronic device, the slot having a mounting portion for being connected to the optical disc drive. The optical disc drive includes a main body; a transfer board having a connector for connecting the main body to the electronic device and at least one opening formed at a side of the connector; and an insulation plate disposed between the main body and the transfer board, and having at least one connecting portion for passing through the opening of the transfer board to be connected to the mounting portion of the slot of the casing of the electronic device, so as to fix the optical disc drive to the slot of the casing of the electronic device. The optical disc drive can be a slim type optical disc driver.
The main body comprises an input/output port and a plurality of coupling holes, which are all formed at a side of the main body.
The transfer board has a transfer port corresponding to the input/output port of the main body and a plurality of screw holes corresponding to the coupling holes of the main body. Further, the opening of the transfer board is a notch extended inwardly from a side edge of the transfer board to the connector of the transfer board.
The insulation plate is formed with through holes respectively corresponding to the transfer port and the connector of the transfer board. The insulation plate is further formed with screw holes corresponding to the coupling holes of the main body and the screw holes of the transfer board, such that screws can be used to pass through the screw holes of the transfer board and the insulation plate to be engaged with the coupling holes of the main body so as to assemble the transfer board and the insulation plate to the main body. Preferably, the connecting portion of the insulation plate is a hook for being connected to the mounting portion of the casing of the electronic device.
The casing of the electronic device further comprises a rear plate. The connecting portion of the insulation plate can pass through the opening of the transfer board to be connected to the mounting portion of the slot of the casing, so as to fix the optical disc drive to the casing of the electronic device and fix the rear plate of the electronic device.
Therefore, the optical disc drive of the present invention has the inherent insulation plate being formed with the connecting portion that can be used to fix the optical disc drive to the casing of the electronic device, without the need of an additional frame, thereby decreasing the fabrication costs. As the connecting portion is preferably a hook that can be coupled to the casing of the electronic device to assemble the optical disc drive to the casing of the electronic device without using any tool, thereby improving the convenience in assembly/disassembly of the optical disc drive to/from the electronic device. The connecting portion or hook can further be coupled to the rear plate of the electronic device when the optical disc drive is fastened to the casing of the electronic device, such that the rear plate can be securely fixed in position.
