A kind of USB connecting line, comprise two USB port, with many signal line that these two USB port electrically connect, these many signal line comprise two power lines and two data wires that are used to transmit data information; This USB connecting line comprises that further at least one and these two power lines electrically connect, and is used to these two power lines that the power interface of power supply is provided.
Preferably, in the described USB connecting line, these two USB port are respectively applied for and connect Portable USB main frame and USB memory device.
Preferably, in the described USB connecting line, one in these two power lines is ground wire.
Preferably, in the described USB connecting line, this power interface is the power interface of USB port form.
Preferably, in the described USB connecting line, these two data wires are the USB differential signal line.
Preferably, in the described USB connecting line, this power interface comprises that one is used for providing the power supply adaptor of adjusting to the power supply of two power lines to this.
Compared with prior art, in the USB connecting line of utility model, comprise that two data wires that are used to transmit data information and one at least one and these two power lines electrically connect, and be used to these two power lines that the power interface of external power source is provided, can realize the transfer of data between Portable USB main frame and the USB memory device, and provide power supply for these two kinds of USB interface equipment simultaneously.
Simultaneously, this power interface is the power interface of USB port form, makes this USB connecting line provide power supply by USB port, makes the use of this USB connecting line more convenient; This power interface comprises a power supply adaptor, can be converted into suitable power supply with being not suitable for direct power supply to the USB interface power devices, increases the scope of application of this USB connecting line; This USB connecting line comprises a plurality of power interfaces of corresponding different interface types respectively, makes this USB connecting line can connect different power supplys to the USB interface power devices, further increases the scope of application of this USB connecting line.
Description of drawings
Fig. 1 is the structural representation of USB connecting line first execution mode of the present utility model.
Fig. 2 is the structural representation of USB connecting line second execution mode of the present utility model.
Wherein, 11,21 first USB port; 16,26 second USB port; 19 power interfaces; 20 power supply adaptors; 17,18,27,28 holding wires.
Embodiment
See also Fig. 1, Fig. 1 is the structural representation of USB connecting line first execution mode of the present utility model.
This USB connecting line 1 comprises: one first USB port, 11, one second USB port 16, the many signal line (indicating) and the power interface 19 that electrically connect with these two USB port.This first USB port 11 and a Portable USB main frame (figure does not show) electrically connect, and this second USB port 16 and a USB memory device (figure does not show) electrically connect.
These many signal line comprise a power line VBUS, one the one USB differential data line DM, one the 2nd USB differential data line DP and a ground wire GND.
The one USB differential data line DM and the 2nd USB differential data line DP are used to transmit mutual data information between this Portable USB main frame and this USB memory device.
This power interface 19 electrically connects with this power line VBUS and this ground wire GND respectively by two holding wires 17,18, and this power interface 19 is used to connect outside power supply, for this Portable USB main frame and this USB memory device provide power supply.
This first USB port 11 can adopt the USB port of different model, to adapt to different environments for use, can adopt public mouthful of Standard-A usually, public mouthful of Mini-B, and perhaps Micro-B is public mouthful.Equally, this second USB port 16 also can adopt the USB port of different model, to adapt to different environments for use, can adopt female mouthful of Standard-A usually.
This power interface 19 can be USB port or other reference power supply input interface, when this power interface 19 was USB port, this USB connecting line 1 can provide power supply to this Portable USB main frame and this USB memory device by any power supply unit that has USB port.This power interface 19 can adopt public mouthful of Standard-AUSB usually, female mouthful of Mini-B USB, and perhaps Mini-AB USB is female mouthful.
When this Portable USB main frame has sufficient electric power, in the time of can satisfying this USB memory device need for electricity, this power interface 19 can be unsettled need not, the power drives that this USB memory device is provided by this Portable USB main frame.
The power shortage that has when this Portable USB main frame, when perhaps the need for electricity of this USB memory device surpasses the power supply capacity of this Portable USB main frame, this power interface 19 connects external power source, by this power line VBUS and this ground wire GND is this Portable USB main frame and the power supply of USB memory device, guarantees the transfer of data between this Portable USB main frame and this USB memory device.If this Portable USB main frame is to use the rechargeable battery power supply, this power interface 19 can also be by this power line VBUS and the battery charge of this ground wire GND to this Portable USB main frame.
