A kind of USB interface-based extender

Technical field

The utility model relates to the signal extender, relates in particular to a kind of USB interface-based extender that can usb signal be transferred to a distant place.

Background technology

Ripe and popularization along with the usb signal technology; USB interface becomes the important interface of computer output; Have many peripheral apparatus as: slide-mouse, keyboard, printer, scanner, drawing board, wireless network card, loudspeaker, MP3 Player or the like use USB interface to transmit data; But the USB line that prior art exists is shorter, can not grow the problem of Distance Transmission, brings very big inconvenience to use.

Summary of the invention

The utility model is the problems referred to above that will solve prior art, proposes the USB interface-based extender that can usb signal be transferred to a distant place.

For solving the problems of the technologies described above; The technical scheme that the utility model proposes is a kind of USB interface-based extender of design, and it comprises: in order to USB input interface, the transmission cable in order to the transmission usb signal that connects the USB input interface, the amplifier in order to the said usb signal of gain amplification that connects transmission cable of importing usb signal, the USB output interface that connects the usb signal after amplifier amplifies in order to output.

Said amplifier comprises: amplify chip and power module; Amplify the data pins of the input pin of chip through transmission cable connection USB input interface, the output pin that amplifies chip connects the data pins of USB output interface; The input of power module is through the power pin of transmission cable connection USB input interface, and the output of power module connects amplification chip power end.

Said power module comprises: the 5V direct current is transformed to the galvanic 3.3V power module of 3.3V and the 5V direct current is transformed to the galvanic 1.2V power module of 1.2V.

Said amplifier and said USB output interface place in the housing.

Compared with prior art; The utility model has been broken through the transmission range restriction of existing USB; Single extender can transfer to 5 meters with usb signal; 8 extender tandem energies transfer to 40 meters with usb signal, provide that the USB peripheral equipment high is integrated, high-quality, high-effect, low-power consumption, low cost solution, effectively solve the extension problem that large space uses the USB peripheral equipment.The utility model is based on USB 3.0 versions, and can backward compatible USB 2.0/1.1 version.Can apply to widely: slide-mouse, keyboard, printer, scanner, drawing board, wireless network card, loudspeaker, MP3 Player, HUB, Skype Phone, digital camera/video camera, externally-connected optical drive, DVD cd-rom recorder, PDA, smart mobile phone, network monitoring video camera, fingerprint identification system, access control and attendance management system.
