Currently, the micro USB method is used for charging and data communication (transmission and reception) of a mobile phone. Cell phones to which this method is applied are essentially accompanied by a cable (hereinafter referred to as a 'cable') having both a micro USB connector and a general USB connector for data transmission and reception with an external device (computer, etc.). There is a hassle of having to always have a cable to perform data transmission and reception.

Because of the complexity of this data transfer and storage process, a cable has been introduced to transfer data stored in a mobile phone directly to a USB flash drive. This is called USB On-The-Go. The USB cottage has a micro USB connector on one side and a USB port on the other side, so the micro USB connector is connected to a mobile phone and a USB flash drive is inserted into the USB port. In other words, USB Orientation acts as a relay that connects your phone and USB flash drive directly without going through a computer.

If four connection terminals T are arranged in a line with a relatively narrow interval and are electrically connected between the drive body 110 and the flash memory 120, the four connection terminals T may be provided in the flash memory 120 with a slight error. There is a risk of improper connection with the terminals. Therefore, in the exemplary embodiment of the present invention, the four connection terminals T are disposed on the crosshairs CL so that the position of the flash memory 120 is perfectly matched with the drive body 110 by the left and right tolerances and the angular tolerances. If not, it is possible to prevent an inappropriate electrical connection between the drive body 110 and the flash memory 120.

It is preferable to be divided and disposed on each. That is, the four pogo pins P are connected to four connection terminals T of the drive body 110 to electrically connect the drive body 110 and the flash memory 120. If four pogo pins P are arranged side by side with relatively narrow intervals as shown in FIG. 5, a fine error occurs when a battery connection is made between the drive body 110 and the flash memory 120. In addition, there is a fear that an improper connection may occur with the four connection terminals T provided in the flash memory 120. Therefore, in the exemplary embodiment of the present invention, the four pogo pins P are disposed on the crosshairs CL 'so that the position of the flash memory 120 may be perfectly aligned with the drive body 110 by the left and right tolerances and the angular tolerances. Even if not matched, an improper electrical connection between the drive body 110 and the flash memory 120 can be prevented.

As shown in FIG. 6, the third permanent magnets 123a and the fourth permanent magnets 123b are disposed so as to correspond to poles different from each other with the first permanent magnets 113a and the second permanent magnets 113b. By magnetically coupling by the attraction between each other it is possible to prevent an inappropriate electrical connection between the drive body 110 and the flash memory 120. In addition, when the drive body 110 and the flash memory 120 are coupled, an error in a direction or an angle may occur. The first magnetic member 113 and the second magnetic member 123 may include two permanent magnets, respectively. The mutually opposed poles are arranged in different poles, further preventing improper electrical contact between the two by attraction and repulsion. For example, when a matching error occurs between the drive body 110 and the flash memory 120, the first permanent magnet 113a and the third permanent magnet 123a may be magnetically coupled by mutual attraction. The permanent magnets 113a and the fourth permanent magnets 123b may induce correct matching of four connection terminals T and four pogo pins P by pushing each other by mutual repulsive force. Similarly, the second permanent magnet 113b and the third permanent magnet 123a are mutually repulsive so that the second permanent magnet 113b and the fourth permanent magnet 123b can be magnetically coupled by mutual attraction. By pushing each other, it is possible to induce the correct matching of the four connection terminals (T) and the four pogo pins (P).

However, the current mobile phone is not provided with a configuration corresponding to the second connector 121 and the second magnetic coupling member 123 provided in the flash memory 120 of the USB flash drive of the present invention. For this reason, by providing a connection connector 210 and a magnetic coupling member 220 in the mobile phone case 200 which is almost essential to protect the mobile phone, the flash of the USB flash drive 100 according to the embodiment of the present invention can be used. By removing only the memory 120 and attached to the mobile phone case 200, it is possible to conveniently transmit and receive data between the flash memory 120 and the mobile phone.
