ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention is related to an assembling structure for portable memory device, and more particularly to a structure of a portable memory device which has small volume and can be easily assembled. The memory device can be easily carried under good protection.
The existent portable memory device of an electric appliances or a computer is used to process or store data. Such portable memory device is required to have small volume and be easily usable and portable. For example, the currently widely used flash RAM module which can be connected with a personal computer or notebook-type computer via a universal serial bus (USB) has small volume and can be easily carried.
However, when carried, the above memory device is generally placed in a pocket or a bag. In action, the protruding elements of the memory device (especially the USB connector) is very likely to be damaged due to collision or abnormal squeezing of alien article. Therefore, a sheath is used to cover and protect the protruding elements from being damaged. In use, the sheath must be taken off and is easy to miss.
Furthermore, due to limitation of volume and precision of the mold, the casings of the mini-type memory device can be hardly assembled by way of insertion or hooking. The casings are simply mated and locked with each other by bolts. Such procedure is time-consuming and troublesome and the appearance of the memory device is poor.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an assembling structure for portable memory device, including a memory device main body composed of a bottom cover, an upper cover and a circuit board. Two corners of one end of the bottom cover is formed with recessed sections. The other end thereof is formed with a thread hole. The upper cover is formed with hook boards and a through hole corresponding to the recessed sections and thread hole. The upper cover is mated and locked with the bottom cover by a bolt to clamp the circuit board. An adapter of the circuit board outward extends from the main body. The memory device can be easily assembled and conveniently used.
It is a further object of the present invention to provide the above assembling structure in which a sheath is fitted around the main body of the memory device. One end of the sheath is formed with a through hole through which the adapter outward protrudes. The sheath and the main body are formed with corresponding stop board and lateral projecting blocks, whereby the main body is slidable within the sheath to extend the adapter out of the sheath or retract the adapter therein. Therefore, the memory device can be easily carried under protection.
