Portable storage device

[0001] 1. Field of the Invention

[0002] The present invention relates to a portable storage device, and in particular to a portable storage device that prolongs the lifespan of a USB connector thereof.

[0003] 2. Description of the Related Art

[0004] Generally speaking, a conventional portable flash memory device and MP3 player usually provides such function for playing MP3 files and data access. As shown in FIG. 1, a conventional portable flash memory device 1 has a USB connector 11. The USB connector 11 can be inserted to the USB port (not shown) of a computer to access information. In addition, the portable flash memory device 1 may be connected to a battery dock 2 to acquire power, in order to carry it anywhere. For example, a user can carry the portable flash memory device 1 and listen to MP3 music by plugging an earphone (not shown) to an earphone port 12. As to the means by which the portable flash memory device 1 is connected to the battery dock 2, the USB connector 11 is plugged into a USB port 21 of the battery dock 2. Thus, power can be transmitted to the portable flash memory device 1 from the battery dock 2.

[0005] Nevertheless, the number of times a USB connector can be plugged into a USB port is limited, approximately 2400. In addition to plug into the USB port of the computer, the USB connector 11 of the portable flash memory device 1 has to plug into the USB port 21 of the battery dock 2 for acquirement power. Thus, the lifespan of the USB connector 11 is further reduced.

[0006] Furthermore, the structure of the USB connector 11 is weak. When the user carries the portable flash memory device 1 to another computer, the USB connector 11 is easily impacted and damaged since it is exposed on surface. In order to protect the USB connector 11 from being damage, we need to combine the USB connector 11 with the battery dock 2. However, the heavy combination of the USB connector 11 and the battery dock 2 reduces the lifespan of the USB connector 11.

[0007] Additionally, functions provided by the portable flash memory device 1 are performed by means of a plurality of buttons 13. Thus, the structure of the portable flash memory device 1 is complicated and the volume thereof is large.

[0008] Hence, there is a need to provide a portable storage device that prolongs the lifespan of the USB connector and protects the USB connector thereof from being damage. Meanwhile, a single control element should be disposed on the portable storage device to replace the conventional buttons 13, thereby simplifying the operation and reducing the volume thereof.

[0009] Accordingly, an object of the invention is to provide a portable storage device. The portable storage device includes a main body and a battery dock. The main body has a connector, a protective element and at least one first power connection portion. The connector and first power connection portion are disposed on the main body. The connector is electrically connected to the data transfer port of an electronic device. The protective element is connected to the main body to protect the connector. The battery dock is connected to the main body and has at least one second power connection portion equally corresponding to the first power connection portion. The second power connection portion is connected to the first power connection portion when the battery dock is connected to the main body.

[0010] Accordingly, the main body is a portable flash memory device and MP3 player.

[0011] Accordingly, the protective element of the main body is a sliding cover connected to the main body.

[0012] Accordingly, the protective element of the main body is a protective cover detachably connected to the main body.

[0013] Accordingly, the protective element of the main body is a bellows-type protective cover flexibly connected to the main body.

[0014] The main body further comprises a single control providing selection of functions thereof.

[0015] The main body further comprises an accessory-attachment loop.

[0016] The main body further comprises an earphone jack. The main body further comprises a write-protection control to prevent data from being written to the main body.

[0017] The battery dock further comprises a battery cover.

[0018] The battery dock further comprises a release button to release the battery cover.

[0019] The surface of the protective element further comprises at least one anti-slip strip.

[0020] Accordingly, the connector is a USB connector.
