83 pressing, second spring 86 makes movable inserting column 85 produce a upward elastic force, but is due to that fixture block 87 is stuck in neck 58,
Movable inserting column 85 is caused to move up, curved handle 55 and movable inserting column 85 are relatively fixed in original place, the mobile electricity for opening mouth
Stream probe, makes wire enter the inner ring of the right binding clip 51 of non-crystaline amorphous metal and the left binding clip 54 of non-crystaline amorphous metal, again to the right by press-bending handle
Hand 55, because the cross-sectional diameter of fixed via 57 is far longer than the cross-sectional diameter of movable inserting column 85, makes fixture block 87 from fixation
Depart from the neck 58 of the inwall of through hole 57, movable inserting column 85 is no longer fixed, elastic force of the movable inserting column 85 in second spring 86
Under effect, restored to the original state after popping up, unclamp curved handle 55, curved handle 55 restores to the original state in the presence of the first spring 56,
The right binding clip 51 of non-crystaline amorphous metal and the left upper end of binding clip 54 of non-crystaline amorphous metal are in close contact, and make the right binding clip 51 of non-crystaline amorphous metal and non-crystaline amorphous metal left
One amorphous alloy iron core of formation of binding clip 54, non-crystaline amorphous metal can measure exchange low current, work in the case where not winding wire
Working frequency scope reaches 50Hz to 100Hz, after having live wire to stretch into, because wire itself, which is powered, produces magnetic field, passes through electricity
Magnetic induction, makes amorphous alloy core inner produce magnetic flux, and the coupling coil 52 wound on amorphous alloy iron core also produces one
Magnetic flux, the inside of such amorphous alloy iron core will produce two magnetic fluxs, and they mutually hinder, and at this moment can make 52 liang of coupling coil
End produces a current data for having no-load voltage ratio multiplying power with wire, and this current data is transferred to single-chip microcomputer after rheostat is adjusted
Processing, single-chip microcomputer is shown the data after processing by the form of numeral on display screen 3, is convenient for people to intuitively check
To the size of surveyed electric current, the rheostatic resistance of access connection circuit board 2 can be adjusted by rotating turncap 4, so as to influence
The measurement result of current probe, reaches the purpose of regulation range, and the utility model is magnetic core using amorphous alloy material, and measurement is handed over
Flow low current more to facilitate, while insertion is provided with fixing device 8 on watchcase 1, the binding clip 5 separated for fixing is used
Get up more time saving and energy saving.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
