Embodiment Construction

[0038] The present invention will be described in more detail below with reference to the embodiments.

[0039] Best practice:

[0040] such as figure 1 , 2 , 3, 4, 5, 6, and 7 anti-stealing electronic energy meters. It includes a front cover 6 , a rear cover 7 , an end button cover 4 , an extension end column 1 , a fixed seal 2 , a hook 3 , and an end button box cover 4 . A hollow epitaxial end post 1 integral with the front cap and open at both ends is arranged upwardly on the matching hole of the front cover 6 and the rear cap 7 , and a cover is provided on the upper open end of the epitaxial end post. 11 is fixed on the epitaxial end post. The cover is a cover of a red plastic sheet, which is bonded to the epitaxial end post by ultrasonic bonding technology. Two through-slots 12 distributed along the axial direction are provided on the extension end post along the axial direction of the end post, and the two through-slots are located at the axial symmetry positions on...

Abstract

The present invention discloses an electricity larceny prevention single phase electronic watt-hour meter, comprising a terminal box cover, a front cap and a rear cap. The front cap is provided with a hole which is used to be cooperated with a thread hole of the rear cap. A hollow outward extending end column with two open ends, which is fixedly and undetachably connected with the front cap, is upward extended from and arranged on the hole of the front cap, and the hole matches the rear cap. The open ends of the outward extending end column are provided with a sealing cap respectively. The sealing cap is fixedly and undetachably connected with the outward extending end column. The electric energy meter of the invention has the advantages that the front cap and the rear cap are closely connected via the outward extending end columns at the two sides of the bottom of the front cap, fixing seals at the left side and right side of a lateral side of the front cap and two pothooks on the top of the front cap. The connection between the front cap and the rear cap is prevented from being prized at four directions by electricity thieves. The seamless connection design between the front capand the terminal box cover ensures that the electric energy meter is prized by using the seam between the front cap and the terminal box cover is prevented. The invention has the advantages of improving the surface shell tightness, the prize-proof and the fake-proof performance, increasing the difficulty and cost of electricity larceny and reducing electricity stealing behavior, thereby achievingthe purpose of reducing loss and improving efficiency.

Description

technical field [0001] The invention relates to a residential electricity metering instrument, in particular to an electronic electric energy meter capable of preventing residents from stealing electricity. Background technique [0002] Electric energy meters are installed in centralized meter boxes in public places to count the electricity used by each household as a proof for paying electricity bills. Since the electric energy meters are installed in public places, the on-site meter boxes are unsupervised and cannot be repaired in time after being damaged, leaving a lot of time and space for electricity theft. As a result, for a long time, some people in the society, driven by interests, unscrupulously steal electricity, and it has become more and more serious, bringing great losses to the national electricity economy. The modification of the electric energy meter accounts for a large proportion of the electricity stealing methods used. Common ways of stealing electricit...
