Novel electric energy meter

Abstract

The invention relates to a novel electric energy meter which comprises a meter shell and a programmable and reset button arranged on the meter shell, the meter shell is provided with a through mounting hole, the programmable and reset button comprises a button body which can be contacted and pressed by a finger, a first elastic reset piece arranged on the side, close to the meter shell, of the button body and a guide column capable of penetrating through the mounting hole, and a limiting piece capable of limiting the guide column in the mounting hole is arranged on the guide column. According to the electric energy meter adopting the design, the programmable and reset button is not easy to slide off from the mounting hole, and the first elastic reset piece is connected with the button body, so that the falling can be avoided, and the assembly of the electric energy meter is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a novel electric energy meter. Background technique [0002] Electric energy meters are usually equipped with programmable and reset buttons. Most of the programmable and reset buttons in the prior art include structures such as button bodies and return springs. The button bodies are directly inserted into the corresponding mounting holes of the watch case without any restrictions. In the process of installation or maintenance, it is very easy to slip from the mounting hole, and because the return spring is not effectively connected to the button body, the return spring is also very easy to fall, which makes the installation and maintenance of the electric energy meter very inconvenient. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a new type of electric energy meter with a programmable and r...
