Description
Technical field
The utility model belongs to electric energy meter accessory technical field, and in particular to a kind of Anti-dismounting structure of plug-in electric energy meter.
Background technology
The power consumption of user is required for being measured by electric energy meter.Adjustment is changed or repaired to traditional electric energy meter when needs
When needing to remove electric energy meter from user terminal, it is necessary to unclamp fixed current line, the screw of pressure-wire, carry out showing for electric energy meter
Field disconnects.Disconnect that traditional electric energy meter was both time-consuming, and operating efficiency is low, and have larger danger.Plug-in electric energy
Table overcomes these shortcomings, but it is possible to which the electric energy meter of plug needs to set anti-disassembling mechanism, to prevent non-electrical industry practitioner random
Plug electric energy meter.
Chinese utility model patent (application number：CN201020647856.5 a kind of tamper of plug-in electric energy meter) is disclosed
Mechanism, including electric energy meter, electric energy meter pedestal and lead sealing screw, the rear portion of electric energy meter include pin, before electric energy meter base shell
Plate includes the slot of electric energy meter pin, and electric energy meter rear portion includes the hook of at least 1 pair vertical direction stretched out backward, hooking slits
