Consult Fig. 1 to Fig. 2, the utility model USB device electric supply installation comprises: a housing 1, one end are provided with the power connection end mouth 5 of an access power supply, and the other end is provided with the power supply port 6 of an output electric energy; One power selection circuit 14, have a manual diverter switch 4, a power supply adaptor 2 and a battery pack 3, Manual Transfer Switch 4 is located on the described housing 1, be used for selecting to insert power supply, power supply adaptor 2 is located in the described housing 1 with battery pack 3, the input of power supply adaptor 2 is connected with power connection end mouth 5 on the described housing 1, selects contact to be connected for one of the output of power supply adaptor 2 and Manual Transfer Switch 4, and battery pack 3 is connected with another selection contact of Manual Transfer Switch 4; One step-down integrated circuit 7 is located in the described housing 1, and the one end is connected with described Manual Transfer Switch 4 fixed contacts, and the other end is connected with power supply port 6 on the described housing 1; One or three end service cables 8, one end are provided with a USB interface 9, in the USB socket that inserts computer, the other end is provided with a USB socket 10, be used for being connected with various USB device, an end is provided with a receiving end mouth 11 in the middle of it, and this receiving end mouth 11 is connected with power supply port 6 on the described housing 1.
Wherein, 11 in 11 in the USB interface 9 of three end service cables 8 and receiving end mouth and USB socket 10 and receiving end mouth have two power lines, also have two signal line between USB interface 9 and the USB socket 10.
Figure 2 shows that an embodiment of the present utility model.Among Fig. 2, the Manual Transfer Switch 4 of USB device electric supply installation is a third gear switch, and step-down integrated circuit 7 is step-down integrated circuit 7805.Power supply adaptor 2 can be selected 220V AC to 9V DC 2200mA model for use, also can select the power supply adaptor of 220V AC to 6V DC 2200mA model for use.Equally, battery pack 3 can be made into the battery pack with 6 groove positions, also can be made into the battery pack with 5 groove positions.
Battery pack 3 with 220V AC to 9V DC 2200mA model power supply adaptor 2 and 6 groove positions is an example.When Manual Transfer Switch 4 was allocated to the gear of power supply adaptor 2, the input 12 of step-down integrated circuit 7 was connected with power supply adaptor 2.The alternating current 220V voltage transitions that power supply adaptor 2 will insert power supply is a direct current 9V voltage, and exports to the input 12 of step-down integrated circuit 7, thereby the output of step-down integrated circuit 7 13 output 5V voltages are to the port 6 of powering.When Manual Transfer Switch 4 was allocated to the gear of battery pack 3, battery pack 3 was connected with the input 12 of step-down integrated circuit 7.If select the common batteries of 6 joint 1.5V for use, then battery pack 3 is exported to the input 12 of step-down integrated circuit 7 with 9V voltage, thereby the output of step-down integrated circuit 7 13 output 5V voltages are to the port 6 of powering.If select the rechargeable battery of 6 joint 1.2V for use, then battery pack 3 is exported to the input 12 of step-down integrated circuit 7 with 7.2V voltage, thereby the output of step-down integrated circuit 7 13 output 5V voltages are to the port 6 of powering.When Manual Transfer Switch 4 was allocated to neutral position, the USB device electric supply installation was not worked.
The input voltage range of 7805 step-down integrated circuits 7 is 6V to 35V, so above-mentioned magnitude of voltage 7.2V and the 9V that inputs to step-down integrated circuit 7 all satisfies condition.And the output voltage 5V of 7805 step-down integrated circuits 7 also satisfies the voltage request of computer USB socket.
If use power supply adaptor 2, then need Manual Transfer Switch 4 is allocated to power supply adaptor 2 gears, the power connection end mouth 5 on the housing 1 is connected with the access power supply.If use battery pack 3, then need Manual Transfer Switch 4 is allocated to battery pack 3 gears, battery correctly is installed in the battery case in the housing 1.
When the phenomenon of electricity shortage appears in the USB device in being plugged on computer USB socket, only need the receiving end mouth 11 of three end service cables 8 is connected with power supply port 6 on the housing 1, Manual Transfer Switch 4 selects to be allocated to power supply adaptor 2 gears or battery pack 3 gears, and another USB socket that the USB interface on the three end service cables 89 is inserted computer gets final product then.
If a USB socket of computer is taken by a USB device, and the phenomenon of electricity shortage has appearred in the USB device in another USB socket, then need the USB device of electricity shortage is pulled up, the receiving end mouth 11 of three end service cables 8 is connected with power supply port 6 on the housing 1, Manual Transfer Switch 4 selects to be allocated to power supply adaptor 2 gears or battery pack 3 gears, then the USB interface on the three end service cables 89 is inserted in the USB socket of computers, got final product and the USB device of electricity shortage is plugged on the USB socket 10 of three end service cables 8.
As further improvement of the utility model, the USB socket 10 on three end service cables, 8 one ends has at least two USB jacks, for the use of pegging graft simultaneously of the USB device of a plurality of electricity shortages.
When using the USB device electric supply installation, only need that Manual Transfer Switch 4 is allocated to neutral position and remove all wiring again, or directly remove all wiring and get final product, very easy to use.
