As a kind of improvement project, described first public plug is USB public plug, and described second public plug is micro-USB public plug.
As a kind of improvement project, described USB mother socket is USB3.0 mother socket.
As a kind of improvement project, also comprise the control circuit board be located in usb hub shell.
As a kind of improvement project, described control circuit board is provided with switching circuit, and described switching circuit is used for described USB mother socket alternatively to communicate to connect with described first public plug, described OTG plug.
As a kind of improvement project, described first public plug is connected to described usb hub by the first cable, and described second public plug is connected to described usb hub by the second cable, and described USB mother socket is arranged in the shell of described usb hub.
Compared with prior art, the USB transmission equipment that the utility model provides is without the need to OTG connecting line, reasonable in design, and structure is simple, makes portable digital product also can carry out transfer of data when not having main equipment.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the USB transmission equipment that the utility model one embodiment provides.
Fig. 2 is the structural representation that OTG plug is as shown in Figure 1 received in usb hub housing.
Fig. 3 is that OTG plug is as shown in Figure 1 connected detail drawing with usb hub housing.
Fig. 4 is the control circuit board schematic diagram in usb hub as shown in Figure 1.
Fig. 5 is the circuit block diagram of USB transmission equipment as shown in Figure 1.
Embodiment
With reference to figure 1 and Fig. 5, USB transmission equipment comprises usb hub 1, the first public plug 2 that can be used as input be connected with usb hub 1, by the second public plug 3 that can be used as output that the second cable 10 is connected with usb hub 1, the USB mother socket 4 that can be used as output be connected with usb hub 1 and the OTG plug 5 be connected with usb hub 1.
In the present embodiment, described first public plug 2 is USB public plug, described second public plug 3 is micro-USB public plug, described micro-USB public plug 3 can be communicated to connect by usb hub 1 and USB public plug 2, described USB mother socket 4 is described USB3.0 mother socket, described USB3.0 mother socket 4 can be communicated to connect by usb hub 1 and USB public plug 2, and described OTG plug 5 can be communicated to connect by usb hub 1 and USB3.0 mother socket 4.
