Description

flash drive

technical field

The invention relates to a storage device, in particular to a flash drive.

Background technique

With the rapid development of flash memory manufacturing technology, large-capacity flash memory is widely used in storage devices. Especially products such as flash drives or thumb drives currently on the market use large-capacity flash memory to reduce the size of the storage device to the size of a thumb.

Today's flash drives most commonly use Universal Serial Bus (USB) as their interface. The casing of the flash drive usually includes a cover to cover the USB connector "when not in use" for dust protection.

However, when the flash drive is used (for example, its USB connector is inserted into a connector of a computer), its cover is placed near the computer. Because the outer cover of the flash drive is small, it is easy to lose. Once the outer cover of the flash drive is lost, the USB connector loses its dust-proof function.

The connector 102a (eg, a USB connector) is used to insert into a corresponding connector slot (eg, a connector slot of a computer) to read or store data. An elastic pad 102b and a bottom plate 102c are also disposed under the body 102e. The elastic pad 102b is located between the body 102e and the bottom plate 102c. Therefore, when the bottom plate 102c is stressed, the elastic pad 102b is also deformed by the pressure of the bottom plate 102c. The hollow housing 104 defines an opening 104a. The hollow shells on both sides of the opening 104a are unequal in length, and the longer side has a recess 104b. The depression 104b has a convex portion. The storage device 102 and the hollow casing 104 can be combined or separated according to usage conditions.

In a preferred embodiment of the present invention, the storage device 102 may include a storage integrated circuit board, the storage integrated circuit board has a storage unit (set in the body 102e), and one end of the storage integrated circuit board is exposed outside the body 102e as a connector 102a, the storage unit in the body 102e can be a memory chip (such as a flash memory).
