Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of new types of data Divulging secret prevention U disk, including USB flash disk shell 100, and
Circuit board (not shown) in the USB flash disk shell 100, the USB flash disk shell 100 are Al-alloy casing, metal material
Shell can reinforce heat dissipation effect, prevent temperature overheating from USB flash disk being caused to damage.The circuit board is equipped with: main control chip 1, USB
Data-interface 2 destroys function button 3, memory module 4 and power module 5.The main control chip 1 respectively with the usb data
Interface 2, destroy function button 3,4 signal of memory module connection, the power module 5 respectively with the main control chip 1 and storage
Module 4 is electrically connected.The USB data interface 2 is connect with PC end signal, realizes the data communication of the USB flash disk Yu the end PC.The electricity
An indicator light 6 is additionally provided on road plate 200, the indicator light 6 is electrically connected with the main control chip 1, in USB flash disk use process, institute
Stating indicator light 6 can light.After pressing the destruction function button 3, the data destroying control that can be triggered on the main control chip 1 refers to
