The utility model belongs to the technical field of safe fortune dimension, in particular to anti -electricity -theft electric energy meter for the electric energy meter easily suffers the surreptitiously technical problem of electricity by U type ring short circuit in solving prior art. Include: table body surface tail sets up insulating barrier, table body surface tail both sides set up the mounting hole, the insulating barrier shape is matchd with table body surface tail shape, and the insulating barrier both sides set up the mounting hole, and insulating barrier is through mounting hole, insulating screw and prevent tearing open nut fixed mounting on table body surface tail, the last wire hole that sets up of insulating barrier, the wire hole position is relative with table body surface tail end mouth position, and the wire hole size is matchd with the electric wire size. Compared with the prior art, the utility model discloses can effectively prevent to steal the emergence of electric accident, improve the power consumption standard, reduce power loss.
