First connector 1 and the second connector 2 be two it is different types of, be respectively used to USB interface with external equipment and computer
The connector of connection（For the present embodiment, the USB interface connection of the first connector 1 and external equipment, the second connector 2
Connected with the USB interface of computer）, and switch element 4 according to the connector 1 of above-mentioned second connector 2 or first and computer or
The supply voltage that obtains during the USB interface connection of communication terminal so that memory cell 3 and be connected to computer or outside
Connector connection in portion's equipment.That is, in the present embodiment, external connection storage apparatus and external storage of the prior art
The difference of device, is that the external connection storage apparatus in the present embodiment has multiple connectors, is adapted to a variety of connect
Mouthful, meanwhile, the external connection storage apparatus is additionally provided with switch element 3, and the switch element 3 is by comparing power end on two connectors
Voltage on son so that memory cell 3 is connected on the connector connected with the corresponding interface.Due to connector and
During corresponding interface connection, its power supply terminal（Generally defined as power supply+）Upper is not in voltage naturally, therefore, to difference
The voltage ratio on power supply terminal on connector more just can interpolate that out the current connector connected with the corresponding interface.
In the present embodiment, said memory cells 3, connector（1、2）Same circuit board 5 is arranged at switch element 4
On（Refer to Fig. 3）, two connectors（First connector 1 and the second connector 2）Be separately positioned on circuit board 5 it is relative two
End.Such setting can make it that a connector, will not the company of obstruction when another connector is connected to corresponding USB interface
Connect.
As shown in Fig. 2 in the present embodiment, switch element 4 includes port identification circuit 41 and electronic switch 42, port is known
Other circuit 41 recognizes the connector connected according to the supply voltage on the power supply terminal respectively from two connectors, and
