Embodiment Construction

[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 and 3 As shown, a specific embodiment of the electric energy meter bottom case fixing device of the present invention, the corner of the electric energy meter bottom case 4 has a screw mounting hole 1 for screw fixing, and the screw mounting hole 1 is a countersunk hole, and the countersunk hole A nut 2 is embedded in the middle. In the present invention, the nut 2 is installed in the countersink after the bottom case 4 of the electric energy meter is injection-molded, which prevents the copper nut 3 from being injected together with the bottom case 4 of the electric energy meter in the traditional method. For potential safety hazard...

Abstract

The invention relates to the technical field of electric energy meters, in particular to a device for fixing a bottom shell of an electric energy meter. Screw installation holes which are used for fixing screws are formed at corners of the bottom shell of the electric energy meter, and the screw installation holes are countersunk holes into which nuts are embedded. The device for fixing the bottom shell of the electric energy meter has the advantages that the conventional copper nuts are replaced by standard piece nuts, so production cost is reduced; the nuts are embedded into the screw installation holes after the bottom shell is formed by injection molding, so hidden danger in the conventional process is avoided; and an embedding type installation mode facilitates convenient and quick replacement of the nuts.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a fixing device for the electric energy meter bottom case. Background technique [0002] Energy meters are instruments used to measure the energy consumed by electrical equipment. According to the sampling source, they are divided into mechanical energy meters, electronic energy meters and electromechanical integrated energy meters. The case of the electric energy meter is divided into a bottom case and an upper cover, and the bottom case and the upper cover are usually connected by screws, such as figure 2 As shown, copper nuts are embedded in the corners of the bottom case of the traditional electric energy meter. The copper nuts are manually put into the injection mold when the bottom case is injected. On the other hand, during the use of the electric energy meter, if the copper nut is damaged or the threaded hole is too large, since the copper nut is injection...
