Abstract
The utility model discloses an in-line copying wire which comprises a master control module, a memory module, a first USB interface and a second USB interface, wherein the memory module, the first USB interface and the second USB interface are all connected with the master control module, a first USB unit connected to the first USB interface is connected with a second USB unit connected to the second USB interface through the master control module, the first/second USB unit supplies power to the master control module, two ends of the master control module are in series connection with two diodes used for preventing short circuit, and the first USB interface and the second USB interface are both USB 2.0 interfaces. The in-line copying wire provided by the utility model has the following advantages: strong practicality, wherein the two USB units do not need to be connected with a computer and can realize communication junction and data transmission only through the in-line copying wire; convenient operation, wherein in usage of the in-line copying wire, the interfaces of the two USB units are plugged into the two USB interfaces of the copying wire at first and then communication connection between the two USB units is established so as to realize data transmission between the two units; a fast transmission speed, wherein the transmission speed is up to 17 MB/s through usage of the USB 2.0 interfaces; and prevention of short circuit, wherein two ends of the master control module are in series connection with the two diodes, so short circuit is prevented.
Description
Technical field
The utility model relates to field of data transmission, relates in particular to a kind of direct insertion to copying line.
Background technology
At present, the USB device memory has USB flash disk, mobile phone EMS memory card, digital camera RAM (random access memory) card etc. multiple, if want from a USB device to another USB device the transmission of data, can only computer, first plug a USB device on the USB interface of computer, the data that will copy out are copied into computer, plug on computers again another equipment, with data copy into, perhaps two USB device are inserted on computer interface simultaneously, operation is on computers implemented copying.In the situation that there is no computer, just can not carry out two USB device data to copying, and this situation is a lot, causes very large inconvenience to people's life.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of direct insertion to copying line.
For achieving the above object, described direct insertion to copying line, be characterized in, describedly direct insertionly comprise main control module to copying line, and the memory module, the first USB interface and the secondary USB interface that all are connected with described main control module communication, the first USB device that is connected to the first USB interface is connected with the second USB device communication that is connected to secondary USB interface by described main control module, and described the first/the second USB device is powered to described main control module.
Preferably, the two ends of described main control module are in series with two diodes that prevent short circuit.
Preferably, described the first USB interface is USB 2.0 interfaces, and described secondary USB interface is USB 2.0 interfaces.
Preferably, described memory module is NAND FLASH.
The beneficial effects of the utility model are,
(1) practical: two USB device can connect computer, only direct insertionly carry out communication connection and transfer of data to copying line by described, and stronger practicality is arranged;
(2) easy to operate: in use, first the interface with two USB device is inserted on two USB interface copying line, and the communication of then setting up two USB device connects, thereby can complete the transfer of data between two equipment;
(3) transmission speed is fast: two USB interface copying line are all adopted USB 2.0 interfaces, and transmission speed can reach 17MB/s.
(4) have anti-short-circuit function: the two ends of described main control module are in series with two diodes that prevent short circuit.
