Description

Technical Field

[0001] This utility model relates to the field of electricity meter data acquisition, and in particular to a detachable data acquisition device for electricity meters. Background Technology

[0002] It can automatically and accurately collect various data recorded by the electricity meter, including cumulative electricity consumption (this is the most basic data, such as how many kilowatt-hours a household user uses in a month), voltage, current, power factor, and other parameters. These parameters are crucial for power companies to understand users' electricity consumption habits and the quality of electricity use.

[0003] Currently, traditional equipment often uses fully threaded fixing or complex snap-fit ​​structures. Disassembly requires loosening each screw or aligning the snaps one by one, which is time-consuming and labor-intensive. Furthermore, existing simple threaded connections are prone to loosening due to vibration or temperature changes, affecting the equipment's sealing and stability. Snap-fit ​​structures are prone to wear and failure, making it difficult to maintain a tight fit for a long time. The outer shell is often a single thin-walled structure with poor impact and deformation resistance, which is insufficient in protecting the internal circuit boards under external forces or long-term use, indirectly increasing development and maintenance costs.

[0004] Therefore, it is necessary to provide a new detachable data acquisition device for electricity meters to solve the above-mentioned technical problems. Utility Model Content
