According to universal serial bus concentrator of the present utility model, the train type that is configured to of described universal serial bus concentrator structure.
According to universal serial bus concentrator of the present utility model, described multiport repeat circuit comprises a microcontroller, the microcontroller expansion bus, the expansion interface bus, suspend and continue circuit, Extended Capabilities Port circuit and USB output interface circuit, described USB input interface connects described microcontroller by serial line interface, described microcontroller connects described microcontroller expansion bus, suspend and continue circuit and Extended Capabilities Port circuit, described Extended Capabilities Port circuit connects described expansion interface bus, suspend and continue circuit and four USB output interfaces.
According to universal serial bus concentrator of the present utility model, described universal serial bus concentrator comprises two fixtures.
According to universal serial bus concentrator of the present utility model, two of described universal serial bus concentrator is configured to wedge shape.
According to universal serial bus concentrator of the present utility model, the side of being configured to, two bodily form of described universal serial bus concentrator.
The utility model expands to a plurality of USB interface by the multiport repeat circuit with a USB interface, connection between each USB interface after will expanding simultaneously is designed to telescopic movable connection method, whereby, the utility model USB HUB can communicate with a plurality of USB device simultaneously, and is not subjected to the volume restrictions of the bigger USB product of volume.
