The invention discloses a multiplex USB cable connector. The connector comprises a transmission line and a USB interface having a USB pin connected to a USB device by the interface at two ends of the transmission line, wherein at least one end of the transmission line is provided with a plurality of USB interfaces; the transmission line is inside integrated or externally connected with a switch used for choosing the USB interface to transmit the transmitting information corresponding to the two ends of the transmission line.
Description
[technical field]
The relevant a kind of wire and cable connector of the present invention relates in particular to a kind of wire and cable connector that electronic device exterior connects that is applied to.
[background technology]
Computer and external equipment be connected and signal has used multiple interfaces and signal transmission form, these interfaces and signal transmission form can incorporate two kinds of communications protocol respectively into: serial communication protocol and parallel communication agreement.
Serial communication protocol has a variety of, and for example: RS232-C, RS-485 and RS-422 etc., popular now USB also is a serial communication protocol.
USB speed ratio parallel port (Parallel Port, for example EPP, LPT) is gone up many with serial line interface traditional computers such as (Serial Port, for example RS-232) with STD bus soon.The maximum transmitted frequency range of USB 1.1 is 12Mbps in the primary standard, and the maximum transmitted frequency range of USB 2.0 is 480Mbps.The USB 3.0 that releases more rises to more than the 4.8Gbps from 480Mbps in the recent period.
USB OTG is the abbreviation of USB On-The-Go, is mainly used in the connection of various equipment room, carries out exchanges data.Particularly PDA, mobile phone, consumer devices.Change as multiple different systems connectors of equipment room such as digital camera, video camera, printers the nearly inconvenience of exchanges data between the storage card of 7 kinds of standards.The development of USB technology makes PC and peripheral equipment various device to be linked together by the manufacturing cost of plain mode, appropriateness, and the above-mentioned application that we mention can be passed through usb bus, as the periphery of PC, carries out exchanges data under the control of PC.But this exchanged form easily, in case left PC, each equipment room can't utilize USB interface to operate, because neither one equipment can serve as the same Host of PC.On-The-Go, promptly the OTG technology is exactly to be implemented under the situation that does not have Host, realizes that the data of equipment room transmit.For example digital camera is directly connected on the printer, by the OTG technology, connects the USB interface of two equipment rooms, and the photograph of taking is printed immediately; Also the data in the digital camera can be sent to by OTG on the portable hard drive of USB interface, field operation just there is no need to carry expensive storage card, perhaps carries on the back a portable computer.
Usually the USB transmitting device of using USB OTG technology is man-to-man duplex data transfer pattern, carries out carrying out between exchanges data and the electrons transmitted equipment (for example: PC, mobile phone, PDA or portable hard drive) transmission of electric signal at two needs.As China's Mainland CN101281421 patent, a kind of jockey is provided, can realize using the MINI USB interface of USB OTG technology and being connected of standard USB interface, this connected mode provides man-to-man transmission means.But when connection object when being a plurality of, this transmission means can be very loaded down with trivial details, can not realize the mode of operation of one-to-many.And in current life or work, the transmission mode of operation of this USB one-to-many scope that has a very wide range of applications again, therefore, a kind of new transmitting device that the one-to-many message transmission mode can be provided just becomes a kind of demand.
[summary of the invention]
The object of the present invention is to provide a kind ofly can connect a plurality of electronic equipments simultaneously and carry out the one-to-many transfer of data, and realize the USB wire and cable connector of main equipment and slave unit selection.
The present invention relates to a kind of multiplex USB cable connector, comprise that transmission line and transmission line two ends are connected to the USB interface that has the USB pin of USB device by interface mode, wherein the USB interface number of at least one end of transmission line is a plural number, transmission line is inner integrated or be circumscribed with the switch of the USB interface that is used to select the corresponding transmission information in transmission line two ends, when connecting a plurality of USB device, each USB device can not conflicted.
Compared with prior art, the present invention has following beneficial effect: by in the inner integrated diverter switch of USB wire and cable connector, the perhaps outside mode that connects diverter switch, make the USB device of supporting USB OTG agreement not only can realize the selection of main equipment and slave unit, realized the transfer of data of one-to-many simultaneously.
