Embodiment Construction

[0034] The present invention will be described in more detail below in conjunction with examples.

[0035] Best practice:

[0036] a kind of like figure 1 , 2 , 3, 4 and 5 shown include end button box cover 1, front cover 2, back cover 3, meter 4, main board and so on. The wire groove hole 11 on the end button box cover is staggered with the wire outlet 6 of the electric energy meter to be staggered along the plane extension direction of the end button box cover, and the distance between the two is 10mm. The terminal button box cover is an extended box cover 12, which covers the wiring part on the electric energy meter, and the length of the outwardly extending part of the terminal button box cover is 30 mm. A limiting device is arranged between the end button box cover and the rear cover, and the limiting device is a circumferential limiting device 7 that limits the relative movement of the end button box cover relative to the rear cover along the periphery of the rear cov...

Abstract

The invention discloses an electricity-filching prevention electric energy meter, which comprises a terminal knob box cover, a front cover and a back cover, wherein the line slot bore on the terminal knob box cover is staggered with the line outlet of the electric energy meter. The invention has the advantages that the in-and-out line slot of the box cover is staggered with the in-and-out line port of the electric energy meter, to prevent electricity filching by inserting wire into the connection part of the electric energy meter, the invention uses prolonged box cover to protect the in-and-out line of the electric energy meter to prevent electricity filching, the terminal knob box cover only can be opened in one way which can not be lifted up by external force, the one-time anti-prying sealing slot can prevent prying, the double protection of the one-time anti-prying sealing and lead seal keyhole can effectively protect the in-and-out lines of the electric energy meter to completely prevent general electricity filching methods. The invention can effectively prevent the modification on in-and-out lines to prevent electricity filching, while the force electricity filching can be exposed.

Description

technical field [0001] The invention relates to a residential electricity meter, in particular to an electronic energy meter capable of preventing electricity theft. Background technique [0002] The electric energy meter is installed on each household to count the electricity used by each household as a proof for paying electricity bills. However, for a long time, some people in the society have been driven by interests to steal electricity by all means, and it has intensified, causing great losses to the national electricity economy. Among the means of stealing electricity adopted, refitting the electric energy meter accounts for a large proportion. The common way of stealing electricity is to cut off the lead seal on the terminal button box cover, open the terminal button box cover of the electric energy meter, and transform the incoming and outgoing lines to achieve the purpose of stealing electricity. There is also a means of stealing electricity, without opening the ...
