Abstract
The utility model relates to a universal serial bus (USB) flash disk provided with an internal USB line-divider, belonging to the technical field of a mobile storage device, and aiming at solving the problem that under the condition that the number of USB interfaces of a computer is limited, other USB interface devices can not be used simultaneously when the USB flash disk is used. The USB flash disk provided with the internal USB line-divider comprises a USB flash disk storage circuit and a line-divider unit; the line-divider consists of a line-dividing controller, a USB interface and a USB plug; a control signal input/ output end of the USB flash disk storage circuit is connected with a control signal output/ input end of the line-dividing controller; an interface control output/ input end of the line-dividing controller is connected with an interface control input/ output end of the USB interface; and a socket control output/ input end of the line-dividing controller is connected with a socket control input/ output end of the USB plug. Therefore, when being used as the USB flash disk, the utility model can provide the USB interface.
Description
Technical field
The utility model relates to a kind of USB flash disk of internal USB deconcentrator, belongs to the movable storage device technical field.
Background technology
USB flash disk, promptly USB flash drive is based on USB interface, is the movable storage device of storage medium with the flash chip, have volume little, be easy to carry, characteristics such as plug and play, in people's work and life, be widely used.USB interface has become the standard interface of computer peripheral equipment at present, and increasing peripheral hardware uses USB interface, for example various movable storage devices, mouse, keyboard, printer, scanner, handwriting pad, camera, digital camera etc.Yet USB interface is limited on the active computer, when not having idle USB interface on computers, needs the extra USB deconcentrator of purchasing and carry, and other USB interface equipment that perhaps interrupt using could use USB flash disk, otherwise can't use.
At present, USB flash disk and USB deconcentrator are separate equipment.Under computing machine USB interface condition of limited, use USB flash disk just might cause other USB interface equipment to use simultaneously, need to cooperate the USB deconcentrator to use.Can cause the inconvenience of carrying and using.
The utility model content
The utility model is in order to solve under the USB interface of computer condition of limited, and the problem of using USB flash disk can cause other USB interface equipment to use simultaneously provides a kind of USB flash disk of internal USB deconcentrator.
The utility model comprises USB flash disk memory circuit and deconcentrator unit,
The deconcentrator unit is made up of a minute lane controller, USB interface and USB plug,
The control signal input/output terminal of USB flash disk memory circuit connects the control signal I/O that divides lane controller; Divide the interface control input/output terminal of the interface control I/O connection USB interface of lane controller, the socket control I/O of branch lane controller connects the socket of USB plug and controls input/output terminal.
Said USB flash disk memory circuit is made up of main control chip, flash chip, write-protect circuit, clock circuit and indicator light circuit,
The control signal input/output terminal of USB flash disk memory circuit is the control signal input/output terminal of main control chip,
The storage signal input/output terminal of main control chip connects the storage signal I/O of flash chip; The write protect signal input end of main control chip connects the write protect signal output terminal of write-protect circuit; The clock signal input terminal of main control chip connects the clock signal output terminal of clock circuit, and the indicator signal output terminal of main control chip connects the indicator signal input end of indicator light circuit.
Said USB interface is one or more.
The utility model has the advantages that: the USB flash disk that the utility model provides is when being used with computing machine; The situation that can not cause other USB interface equipment to use because of having taken USB interface of computer; It rolls into one USB flash disk function and USB deconcentrator function, carries and easy to use.
The utility model both can connect the USB flash disk of USB peripheral hardware, can not cause again and monopolize USB interface of computer, had low, the simple in structure and small and exquisite practical characteristics of cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model when USB interface is one;
Fig. 2 is the structural representation of the utility model when USB interface is two;
Fig. 3 is the structural representation of the utility model when USB interface is three.
