Connectable USB flash disk

Abstract

The invention discloses a connectable USB flash disk which comprises a shell, wherein a flash memory card and a circuit board connected with the flash memory card are arranged in the shell; a USB plug is connected with the circuit board by virtue of a flexible circuit; a cavity for containing the USB plug is formed inside the shell; the cavity is communicated with an open slot formed in one end of the shell; sliding rails are symmetrically arranged on cavity walls at the left and right sides of the cavity; slide blocks connected with the USB plug are arranged on the sliding rails; a mounting slot is formed in a part, which corresponds to the sliding rail at one side, of the shell; the USB plug can extend out of the open slot in the mounting slot formed in the slide block at one side by pushing the slide blocks; a USB socket is arranged at the other end, which is opposite to the open slot, of the shell; multiple card reader slots are formed in the left and right sides of the shell; and the USB socket and the card reader slots are connected with the circuit board. The connectable USB flash disk disclosed by the invention is good in practical effect and high in self-utilization rate, can simultaneously meet multiple different requirements and has high market value.

Description

technical field [0001] The invention relates to a mobile storage device, in particular to a connectable U disk. Background technique [0002] With the continuous development of modern electronic products, U disk has become the most commonly used mobile storage device. Compared with mobile hard disk, although U disk cannot compete with it in storage capacity, it is small, light and easy to carry. Simultaneously, along with the continuous increase of the capacity of USB flash disk, USB flash disk has become a kind of mobile storage device that people more and more favor. [0003] Most of the existing mobile USB flash drives are outdated in shape and single in function, which cannot meet people's various demands for use. The traditional U disk usually adopts a cap type or a rotary type at the port. Due to the small size of the cap, the cap-type U disk is often lost after opening; the rotating U disk is prone to the phenomenon that the port is not easy to open; secondly, due t...

AI Technical Summary

Problems solved by technology

Due to the small size of the cap, the cap-type U disk is often lost after opening; the rotating U disk is prone to the phenomenon that the port is not easy to open; secondly, due to the limited number of USB sockets on the computer, when multiple devices need to be connected, the socket often appears. Insufficient phenomenon; Again, the ports and jacks of the existing U disk are often exposed to the outside, and when the time is long, they are easily polluted by dust, water, etc., causing them to be unusable; meanwhile, due to the small size of the U disk, In the process of carrying, it is often easy to lose, causing unnecessary waste
