[0044] The use principle of the utility model is now described as follows:

[0045] Example 1

[0046] A pulling force is applied to the disconnect cover 5 in the direction of the staff, and the inclined surface of the clamping portion 52 causes the clamping portion 52 to gradually move downward and store energy in the clamping portion 52 until the clamping portion 52 is separated from the fixing hole 12. The clamping portion 52 is reset, and the disconnect cover 5 is rotated to face the staff. The cam 51 leaves the cross block 311, and the first spring 33 releases its elastic force to push the cross block 311 out, so that the disconnect contact piece 32 abuts against the two conductive terminals 2 to ensure normal power supply for the user. Figure 1 , Attachment Figure 2 As shown, at the same time, the current flows through the disconnect contact piece 32 and the second spring 43, and supplies power to the circuit board 41. The sound module 42 issues a voice prompt of "The equipment is energized, please pay attention". At the same time, the LED light 44 lights up red to warn the staff that the conductive terminal 2 is currently energized and they should be careful when working. At this time, the energy meter can be replaced without interrupting the power supply.

[0047] Example 2

[0048] When the electric energy meter is replaced, the disconnect cover 5 is rotated, and the clamping portion 52 gradually moves downward along the chamfer 13, and the clamping portion 52 is energized until the clamping portion 52 is just below the fixing hole 12. The clamping portion 52 releases its elastic force, and the clamping portion 52 enters the fixing hole 12, ensuring that the disconnect cover 5 is stably connected to the terminal block 11. At the same time, the cam 51 pushes the cross block 311 to retract, so that the pressure rod 31 moves toward the sealing plate 6, so that the first spring 33 and the second spring 43 are energized, so as to prepare for the next uninterrupted power replacement of the electric energy meter. Figure 3 , Attachment Figure 4 The contact piece 32 is disconnected from the conductive terminal 2, so that the energy meter can measure energy normally, the circuit board 41 loses power supply, and the sound module 42 and the LED light 44 stop working.
