ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an insertion cartridge for hard disc of portable computer, and more particularly to a hard disc insertion cartridge which can be easily assembled with the portable computer so as to reduce the manufacturing cost of the portable computer. In addition, the insertion cartridge has an electromagnetic wave protection function.
2. Description of the Related Art
The base of a conventional portable computer and the hard disc of the portable computer are manufactured and assembled with each other in such a manner that the bottom of the hard disc is formed with multiple thread holes (generally six, three on each side ) for locking the hard disc. The base of the portable computer is also formed with multiple thread holes corresponding to the thread holes of the hard disc. When the hard disc is assembled with the portable computer, screws are screwed into the thread holes to fix the hard disc with the portable computer. According to such assembling procedure, quite a lot of screws must be used to lock the hard disc. In addition, such locking procedure must be performed manually so that it is troublesome to manufacture the portable computer. This leads to high cost for manufacturing the portable computer.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an insertion cartridge for hard disc of portable computer, which facilitates the manufacturing and assembling of the base of the portable computer and the hard disc. The insertion cartridge also reduces the interference of electromagnetic wave with the hard disc in operation and prevents electromagnetic wave from escaping. When assembling the hard disc with the portable computer, the hard disc is first enclosed in the insertion cartridge and then the insertion cartridge with the hard disc is fitted into the portable computer with the connector of the hard disc electrically connected with the hard disc connector of the portable computer. Then, the insertion cartridge with the hard disc is locked with the base of the portable computer by locking members.
It is a further object of the present invention to provide an electromagnetic wave protective insertion cartridge for hard disc of portable computer, which is able to prevent electromagnetic wave from interfering with the hard disc or escaping.
The present invention can be best understood through the following description and accompanying drawings wherein:
