Integrated electric energy meter shell

Abstract

The invention discloses an integrated electric energy meter shell. The integrated electric energy meter shell is characterized by comprising a bottom shell, a lens frame and a lens, wherein the bottom shell and the lens frame are made of plastic, the lens is made of a transparent PC material, the lens is fixedly installed in the lens frame, the lens frame fixedly covers the bottom shell to form the hollow electric energy meter shell, the bottom shell and the lens frame are welded ultrasonically, and the lens frame and the lens are welded ultrasonically. The structural strength of the electric energy meter shell can be improved, the material cost and labor cost are saved, the production efficiency is improved, and electricity larceny prevention performance of an electric energy meter is improved.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to an integrated electric energy meter housing. Background technique [0002] With the advancement of science and technology and the continuous development of electronic technology, electronic energy meters have many advantages such as high precision, multi-function, low power consumption, small starting current, wide load range, and no mechanical wear, and are more and more widely used. . [0003] Electronic watt-hour meters usually include bottom case, mirror frame, lens, terminal block, meter tail and other components. Bolts are usually used to connect the bottom case and mirror frame, but this method has the following disadvantages: high material cost, slow assembly speed, and easy bolting. Looseness, gap sealing after assembly is poor. The frame and the lens are usually mechanically matched, and the hook on the lens is fixed with the hole of the frame. This method has...

Problems solved by technology

[0003] Electronic watt-hour meters usually include bottom case, mirror frame, lens, terminal block, meter tail and other components. Bolts are usually used to connect the bottom case and mirror frame, but this method has the following disadvantages: high material cost, slow assembly speed, and easy bolting. Looseness, gap sealing after assembly is poor

The frame and the lens are usually mechanically matched, and the hook on the lens is fixed with the hole of the frame. This method has the following disadvantages: high production requirements for the lens, poor injection molding of the hook, slow assembly speed of the lens and frame, and easy assembly of the frame and lens after assembly. There are gaps, flatness differences between the lens and the frame, etc.
