Abstract
The utility model relates to a USB cable, compromising a USB cable and two standard USB joints that are connected with two ends of the cable. One joint is applied to connect USB port equipment. The other joint is applied to joint the computer. The utility model is characterized in that USB cable is connected with the joint of a power supply wire in parallel. At the time of using the utility model, the electricity consumption is limited within the scope of power supply of USB. The power supply joint can be idled, and only use the USB standard joint to supply electricity. When USB port equipment is needed to use large electricity consumption, the idled power supply joint can be plugged into the plugs for supplying electricity, such as special 5V power supply plug or mouse and keyboard of computer.
Description
The utility model relates to a kind of connecting line, particularly about a kind of USB cable that can expand power supply capacity.
Universal day by day along with computer, the ancillary equipment that is connected with computer is more and more, yet because the amount of power supply of the USB interface of general computer all is limited in below 500 milliamperes, therefore the USB interface equipment that some power consumption is bigger must other stand-by power source or cable is made into the compound cable (is the utility model patent of CN2401974Y as notification number) of twin-core, this not only makes on the USB interface equipment will be provided with the power line socket more, makes compound cable and also acquires a certain degree of difficulty.
At the problems referred to above, the purpose of this utility model provides and a kind ofly on USB interface equipment outlet need not be set, and just can provide various power supply capacities, and USB cable easy to make.
For achieving the above object, the utility model is taked following design: a kind of USB cable, it comprises a USB cable and is connected the two standard USB joints at described cable two ends, wherein a joint is used to connect USB interface equipment, another joint is used to connect computer, it is characterized in that: a power cord connector in parallel on described USB cable.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to use the USB cable of a mark awl, and on described USB cable a power cord connector in parallel, therefore when power consumption exceeds the amount of power supply of computer mark awl USB interface, only need the power connection of parallel connection is inserted on 5 volts of special-purpose power supplys, or be inserted in PS/2 interface power takings such as mouse, keyboard, and the amount of power supply of the USB cable that is above standard just can be provided, reach the electricity consumption requirement of this USB interface equipment.2, the utility model is owing to be to adopt by the power connection of parallel connection to expand the power supply capacity of USB interface for the mode of USB cable power supply, electrical problem with the USB interface equipment that solves big power consumption, therefore do not need to establish power interface in addition to USB interface equipment, do not need the interface of USB interface equipment is carried out any improvement yet, more do not need to make twin cable, so it possesses, and cost of manufacture is low, the connecting interface standardization, advantage such as convenient to operation, it can be widely used in being connected of computer and various USB ancillary equipment.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation
As shown in Figure 1, the utility model comprises the USB cable 1 of a standard, and the USB joint 2,3 of a standard is set respectively at the two ends of cable 1, and its center tap 2 is used to connect USB interface equipment, and joint 3 is used to connect the USB socket on the computer.Characteristics of the present utility model are power connections 4 in parallel on the cable 1 of joint 3 one ends, the power line that is about in the USB cable 1 is connected with power connection 4, this joint 4 can be connected with 5 volts of power source special sockets, also can be connected power taking with sockets such as mouse on the computer, keyboards.
When the utility model used, power consumption just can be vacant with power connection 4 in the amount of power supply scope of USB interface restriction, only uses USB modular connection 2,3 power supplies; And when the power consumption of USB interface equipment is big, just can 5 volts of outlets of vacant power connection 4 insertion special uses on, also can with the mouse socket of computer or keyboard jack or other socket on power.
