Abstract
The utility model relates to a U disk with the functions of a USB (universal serial bus)-HUB, which comprises a U disk main body, a USB male head, a USB-HUB chip, a master control chip, a flash memory chip, USB female heads and conducting wires, wherein the USB male head, the USB-HUB chip, the master control chip, the flash memory chip and the three USB female heads are arranged on the U disk main body, the conducting wires are used for connecting a voltage plus and minus interface and a data plus and minus interface of the USB male head onto the USB-HUB chip, the voltage plus and minus interfaces and the data plus and minus interfaces of the three USB female heads are respectively connected with the USB-HUB chip through the conducting wires, and the master control chip is connected with the USB-HUB chip and the flash memory chip through the conducting wires. The U disk has the advantages of being convenient to carry, providing additional three USB interfaces, enabling a computer to be simultaneously connected into more USB devices, avoiding additional wiring, saving space of a computer desk and facilitating the use of people.
Description
Technical field
The utility model relates to a kind of computer product, the USB flash disk of a kind of self-carried USB-HUB function of saying so more specifically.
Background technology
USB mobile storage disc (USB flash disk) is the computer peripheral unit part of using always, because of its small and exquisite be easy to carry, memory capacity is big and obtained using widely.
At present, computing machine more and more uses USB interface to carry out communication, USB interface becomes the most frequently used interface of computer peripherals gradually, uses the equipment of USB interface also to grow with each passing day, for example USB flash disk, digital camera, printer, keyboard, mouse, scanner etc.People tend to run into the not enough situation of USB interface on the computer when using these USB device, when using several USB device at the same time, after we often need the USB device of using extracted computer, again another USB device is inserted computer, make troubles to the user.Be a plurality of USB interface though also there is technology that a USB interface is expanded now, promptly external usb hub, people need extra wiring in use, make the wiring complexity of computer, and external usb hub itself has also taken the space of computer desk simultaneously.And external usb hub volume is bigger, is not easy to carry.
The utility model content
The purpose of this utility model is the USB flash disk that a kind of self-carried USB-HUB function is provided in order to solve existing issue, and this USB flash disk can provide three extra USB interface, can use other USB device when using this USB flash disk by these interfaces.
The purpose of this utility model can realize in the following manner: the USB flash disk of a kind of self-carried USB-HUB function, comprise the USB flash disk main body, the USB male, the USB-HUB chip, main control chip, flash chip, USB female and lead, the USB flash disk main body is provided with the USB male, the USB-HUB chip, main control chip, flash chip and three USB females, lead is with the voltage "+" of USB male, "-" interface and data "+", "-" interface is connected on the USB-HUB chip, the voltage "+" of three USB females, "-" interface and data "+", "-" interface links to each other with the USB-HUB chip by lead respectively, and main control chip links to each other with flash chip with the USB-HUB chip by lead.
Three USB females lay respectively at three sides of USB flash disk.
The utility model compared with prior art has following advantage: be convenient for carrying, three extra USB interface are provided, can make computing machine insert more USB device simultaneously, and not have extra wiring, saved the space of computer desk, made things convenient for people's use.
