A kind of portable clamp on amperemeter
Technical field
This utility model is related to electronic measuring technology field, more particularly to a kind of portable clamp on amperemeter.
Background technology
At present, it is with the development of circuit engineering, either in large enterprise or little to home circuit, all it be unable to do without electricity
Use, various electrical measurement instruments are derived for this, the use of ammeter is related among these, but common ammeter
Simple structure, single function, during use, accuracy rate is also not high enough, not with display screen display function, needs us according to reading
Disk reading, when there is the electric current in certain error, and measuring circuit, needs first open circuit, then connects loop to measure, it is impossible to
Carry out connecing electrical measurement, with certain limitation.
Utility model content
The purpose of this utility model is and a kind of portable pincer for proposing in order to solve shortcoming present in prior art
Ammeter.
To achieve these goals, this utility model employs following technical scheme:
A kind of portable clamp on amperemeter, including shield, the two poles of the earth incoming end, battery box body and fuselage, the body upper
Shield is installed, inside the shield, installs cored, and iron core surface is provided with copper cash winding, is provided with above the shield
Regular jaw, and regular jaw surface is provided with insulation leather sheath, the fuselage surface installs polarity incoming end, and the two poles of the earth are accessed
End right side is provided with and off switch, is provided with above range control button, and range control button above the two poles of the earth incoming end
Display screen is installed, is provided with the right side of the fuselage on the right side of battery box body, and battery box body and battery case lid is installed, the battery
Battery fixing groove is installed inside box body, and battery fixation rooved face is provided with and connects electrical contact.
Preferably, Anti-slip handle is installed below the battery box body.
Preferably, Anti-slip handle is installed below the battery box body.
Preferably, calibration knob is just installed with the battery case.
Preferably, range dial plate is installed above the display screen.
In this utility model, by being provided with the elastic spanner of jaw, power-assisted can be played a part of, us can be facilitated to beat
Regular jaw is driven, external measurement electric wire is clamped, current transformer principle, nothing can be realized by installing cored and copper cash winding
Need open circuit, so that it may measure electric current, with certain practicality, by being provided with two-stage incoming end, it is possible to achieve the work of circuit tester
With, voltage and resistance can be surveyed, calibration knob is installed by being arranged on the right side of fuselage, ammeter can be corrected at any time, increasing
The accuracy of power-up flow table, and this kind of clamp on amperemeter reasonable price, practical function.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of portable clamp on amperemeter, including shield 1, the two poles of the earth incoming end 5, battery box body 9 and fuselage
10, shield 1 is installed above fuselage 10, cored 15 is installed inside shield 1, and 15 surface of iron core is provided with copper cash winding 7, protected
Regular jaw 6 is installed above cover 1, and 6 surface of regular jaw is provided with insulation leather sheath 14,10 surface of fuselage is installed polarity and connect
Enter and on and off switch 13 is installed on the right side of end 5, and the two poles of the earth incoming end 5, range control button 4 is installed above the two poles of the earth incoming end 5, and
Display screen 11 is installed above range control button 4, is provided with the right side of fuselage 10 on the right side of battery box body 9, and battery box body 9 and is installed
There is a battery case lid 17, battery fixing groove 18 is installed inside institute battery box body 9, and 18 surface of battery fixing groove is provided with and connects electricity and touch
16, Anti-slip handle 12 is installed below battery box body 9, jaw elastic spanner 2 is installed, in battery box body 9 on the right side of fuselage 10
Side is provided with calibration knob 8, and range dial plate 3 is provided with above display screen 11.
Operation principle:When using this kind of portable clamp on amperemeter, we open the battery on the right side of battery box body 9 first
Lid 17, is provided with aneroid battery to the inside of battery fixing groove 18, then our power-on switch 13, and adjusts range control and press
Button 4, now range dial plate 3 start to rotate, and show range index, last we press the elastic spanner 2 of lower jaw, now fixation clamps
Mouth 6 is in open configuration, and regular jaw 6 need to only be clamped the circuit for needing measurement for we, by cored 15 He of installation
Copper cash winding 7 can realize current transformer principle, without the need for open circuit, so that it may measure electric current, by being provided with two-stage incoming end 5,
The effect of circuit tester can be realized, voltage and resistance can be surveyed.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, should all cover in protection model of the present utility model
