Abstract

The invention relates to an electric energy meter and a key combined structure thereof. The combined structure comprises an upper cover, a plurality of keys and a plurality of switch keys. The plurality of keys are embedded in the upper cover. The plurality of switch keys correspond to the plurality of keys, and are arranged on a printed circuit board (PCB) mainboard. Each key comprises a key column, a keycap and a key pressing plate, wherein the keycap is embedded into the upper cover, and covers the top end of the key column; the key pressing plate has a through hole; the key column penetrates through the through hole; and the bottom end of the key column is opposite to a corresponding switch key, and directly contacts the corresponding switch key when pressing the keycap. The key columns and the key pressing plates are added, and conductive particles and a key PCB are eliminated, so that the aim of key-pressing operation is fulfilled by pressing down the keys to make the key columns directly act on the switch keys when the electric energy meter is used, and the electric energy meter and the key combined structure thereof have high antistatic capability, sealing performance and water tightness.

Description

technical field [0001] The invention belongs to the technical field of electric energy meters, and in particular relates to an electric energy meter and its button composite structure. Background technique [0002] Electric energy meter has great potential for development in our country, although it started late, but the momentum is very fast. In view of the vast territory of our country, the grid structure, grid layout and load conditions are different in different regions, even in different regions of the same city. Based on the principle of reducing costs and improving reliability, various suitable smart grids have been developed according to local conditions. Meter. In this way, a city or electric power bureau can truly realize the automatic monitoring and dispatching management system of electric energy, which makes my country's electric energy automatic management level take a big step forward. [0003] The electric energy meter generally includes a watch case and fu...
