Description

U disk with special-shaped interface

Technical Field

The utility model relates to a storage device technical field specifically is a USB flash disk of dysmorphism interface.

Background

The USB flash disk is an important mobile storage device, and in the prior art, the USB flash disk exchanges data with a computer through a USB interface. With the rise of smart devices, for example, smart phones or tablet computers can also be used as data storage, but due to the storage capacity limitation of smart devices, the usb flash disk becomes the most economical external storage.

The U disk is a type of flash memory and is sometimes referred to as a flash disk. The U disk is different from the hard disk in that the U disk does not need a physical driver, is plug and play, has storage capacity far exceeding that of a floppy disk, is very convenient to carry, and integrates a magnetic disk storage technology, a flash memory technology and a universal serial bus technology.

In the audio and video player industry, such as the old people playing games, the original conventional U disk is large in size, large in size and occupies a large area when being installed on a player, easy to fall off due to the fact that the conventional U disk is easy to touch, high in cost and difficult to maintain, and therefore the U disk with the special-shaped interface is urgently required to be developed aiming at the current situation so as to overcome the defects in the current practical application.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a USB flash disk of dysmorphism interface to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a USB flash disk of dysmorphism interface, USB flash disk of dysmorphism interface includes:

PCBA board;

the public first interface, public first interface is located on the PCBA board, just public first interface does gilt pad on the PCBA board.

As a further aspect of the present invention: the male connector consists of four interfaces, wherein the four interfaces are VCC +5V, DATA +, GND and DATA-from left to right.

As a further aspect of the present invention: the PCBA board is also provided with a USB controller chip, a chip resistor, a memory and a chip capacitor.

As a further aspect of the present invention: the memory is a Nand-flash memory.

Compared with the prior art, the beneficial effects of the utility model are that:

when external or built-in USB flash disk on audio and video player trade equipment and other convenient equipment, through special-shaped USB flash disk design application PCBA board 1 on the gilt pad as USB's public first interface 2, with the TF draw-in groove that corresponds on the equipment as USB's female first interface, in the use, special-shaped USB flash disk is all outstanding than ordinary USB flash disk in cost and structure, reasonable in design not only, moreover, the steam generator is simple in structure, and is small, the cost is saved, high use efficiency, and have detachability, facilitate the use and maintain, for the user provides convenience, and is worth promoting.

Drawings
