Description

A double-sided pluggable U disk

technical field

The utility model belongs to the technical field of data storage and relates to a U disk, in particular to a double-sided pluggable U disk.

Background technique

U-disk, the full name is "USB flash drive", and the English name is "USB flash disk". It is a miniature high-capacity mobile storage product without a physical drive, which can be connected to a computer through a USB interface to achieve plug-and-play. The name of the U disk originated from a new type of storage device produced by Netac, named "U disk", which is connected with a USB interface. After the USB interface is connected to the host of the computer, the data of the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technologies produced later, they can no longer be called "USB disks", but are renamed "U disks" with homophonic sounds. Later, the name U disk was widely known because of its simplicity and ease of remembering, and until now the two have been used in common, and no distinction is made between them. It is one of the mobile storage devices.

The existing USB flash disk has positive and negative directions, and it can be used only when it is inserted into the computer in the forward direction of the USB flash disk, and it cannot be used if it is inserted in the reverse direction. Thereby bring inconvenience for people's use, also do not have the method that solves the above problem to occur now.

Utility model content

The technical problem to be solved by the utility model is to provide a double-sided pluggable USB flash drive, which can be plugged into computers or other electronic devices in both directions, which brings convenience to people's use.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A double-sided pluggable U disk, the U disk includes: a double-sided pluggable USB interface, a main control chip, and a flash memory chip;

The main control chip is respectively connected to a USB interface and a flash memory chip for exchanging data between the computer and the flash memory chip;

The USB interface includes a plug mechanism, the two sides of the plug mechanism are respectively provided with conductive terminals, and each conductive terminal is respectively connected with the main control chip.

As a preferred solution of the present invention, the USB flash drive also includes a PCB board, on which the main control chip and the flash memory chip are arranged; the two conductive terminals of the USB interface are respectively connected to the PCB board.

As a preferred solution of the present invention, the conductive terminal includes a 5V voltage line, a ground line and two data lines.

The beneficial effect of the utility model is that: the double-sided pluggable U disk proposed by the utility model can be inserted into a computer or other electronic equipment in both positive and negative directions, which brings convenience to people's use.
