The USB interface voltage and current tester disclosed by the utility model has the characteristics of simple operation and convenient use.
Description
Technical field
The utility model relates to the voltage and current tester of a kind of tester, particularly a kind of USB interface.
Background technology
Along with popularizing of the miniature portable digital equipments such as mobile phone, panel computer, vehicle-mounted Mp 3 player and enriching constantly of kind, this only is equipped with interface on computers originally USB interface, power supply or charging inlet as these equipment appears at other independent occasions more and more, such as charger for mobile phone, portable power source, even on automobile.When USB interface becomes a kind of power supply interface of standard day by day, when becoming a part indispensable in our life, we have some queries unavoidably: these equipment are the great power of actual consumption in by the power taking of USB mouth or charging? whether the output voltage of USB mouth accurate? can this USB mouth reach great output current? traditionally, measuring the voltage of USB mouth must be measured with the voltage tester instrument of multimeter and so on, measure in the electric power connection line that the electric current that is connected to the current consuming apparatus on USB interface needs current measurement instrument is connected between USB mouth and equipment and could realize, process is loaded down with trivial details, and require the operator must possess basic electricity knowledge.
The utility model content
The purpose of this utility model is, a kind of USB interface voltage and current tester is provided.The utlity model has characteristics simple to operate and easy to use.
The technical solution of the utility model: USB interface voltage and current tester, it is characterized in that: comprise housing, housing one end is provided with the USB male seat, the other end is provided with the USB female seat, be provided with the MCU control module in housing, the MCU control module is connected with the USB male seat through voltage detection module, and the MCU control module is connected with the USB female seat through current detection module, and the MCU control module also is connected with the display that is arranged on surface of shell.
In aforesaid USB interface voltage and current tester, also be provided with switch on described housing.
In aforesaid USB interface voltage and current tester, described display is charactron display or LCD display.
Compared with prior art, the utility model inserts USB plug (male seat) in USB interface to be tested, in the situation that the output voltage of this USB interface can be directly read in the USB interface energising by the voltage and current display screen arranged on fuselage, as long as will insert in the USB socket (female seat) of fuselage other end setting such as power taking equipment such as mobile phones simultaneously, the electric current on display screen shows that part will show the working current of this equipment in real time.This detector allows the user can understand intuitively real-time output voltage and the working current of USB power supply interface, calculates the real time power consumption of power taking equipment, has very strong practicality and operation simplification, also greatly facilitates the user.The utility model also has the characteristics simple in structure of implementing.
