AI Technical Summary
Technical Problem
The buttons on existing electricity meters and data acquisition terminals use spring reset, which results in more parts and assembly processes, increasing production costs.
Method used
The button adopts a self-rebound button design, which utilizes the first and second inclined springs on the button base to drive the button to rebound through the elasticity of the springs. This reduces the reliance on springs, simplifies the assembly process, saves the step of installing springs, and reduces the number of parts.
Benefits of technology
It reduced production costs, simplified assembly processes, and improved button rebound performance and user experience.

Abstract
The utility model discloses a kind of self-rebound keys and electric energy meter and collection terminal containing it, wherein self-rebound key includes key seat, the bottom wall of the key seat is equipped with the connecting column extending downward, the bottom wall of the key seat is provided with the first spring leaf of obliquely downward setting, the first spring leaf is located the outer circumferential side of the connecting column. By setting first spring leaf on key seat, the elasticity of first spring leaf is used to drive the whole key to rebound, without additional spring to make the key rebound, the process of installing spring can be saved, the number of parts is reduced, which is conducive to reducing production cost.
