[0054] Working principle: In the first step, the back plate 1 of the present application is fixed to the installation position through the installation hole 101, and is connected to the electric energy meter through four copper pillars 301. The four copper pillars 301 are connected to the terminal 4 through the grooves 302 opened in the copper block 3 to achieve power-on. When the electric energy meter needs to be replaced, first, the limit plate 5 and the cover plate 2 are disengaged from the limit, and then the toggle handle 201 is buckled to drive the cover plate 2 as a whole to separate from the back plate 1, and the snap-in groove 202 is disengaged from the snap-in groove 102. The mounting seat 203 rotates based on the first rotating axis 106 through the second through hole 204.

When the copper block 3 is out of contact with the terminal 4, the electric energy meter connected to the copper pillar 301 is powered off and the copper pillar 301 is powered off. At this time, the electric energy meter can be replaced in the powered state.

[0055] In the second step, the plug-in mechanism of the present application is not only limited by the limit plate 5, but the snap-in groove 202 on the back of the cover plate 2 can also be limited by the snap-in groove 102, which has higher stability. The copper block 3 of the plug-in mechanism is not easy to separate from the terminal 4, so that the present application has higher stability.

[0056] In the third step, the limit plate 5 of the present application is fixed by the two clamping bolts 503 and the limit protrusion 107. The clamping bolt 503 and the limit protrusion 107 can be disengaged from the limit by simply pulling the lever 502. Then, the clamping slot 202 can be separated from the clamping slot 102 by simply pulling the toggle handle 201 to flip the plug-in mechanism. Compared with the bolt and nut type limit, the limit of the present application is easy to cancel.
