The loop sensor；In-line induction coil fixed column is provided with inside the front cover body, U-shaped sense is provided with inside the rear cover body
Answer coil fixed column.
The rear base has battery case, and battery is provided with the battery case；The rear cover body has circuit board slot, institute
State and circuit board is installed in circuit board slot, the circuit board is fixed by screws on rear cover body, the battery and the circuit
Plate electrically connects, the sensor and the circuit board electrical connection.
It also includes a clamping plate in the through hole of the box-like housing central section, and the clamping plate passes through two screws and institute
Rear cover body is stated to be connected.
The beneficial effect of technical scheme provided by the utility model is：
1st, the utility model micro current equipment, due to using above design, during installation, by box-like housing and ring
Shape sensor is taken apart, and in the case where equipment under test does not power off, U-shaped induction coil is set on the circuit for not had equipment, then by U
Shape induction coil and in-line induction coil are got up with mode connects for screw, and then box-like housing is assembled and can used again.Thus
It can be seen that the utility model micro current device structure is simple, it is easy to use, and the situation of equipment live can be measured
Under installed, do not influence be measured equipment work.
2nd, the utility model micro current equipment, because it also includes one in the through hole in the middle part of the box-like body
Clamping plate, the clamping plate are connected by two screws with the rear cover body, be easy to by micro current equipment be fixedly attached to by
Measuring apparatus.
