Problems solved by technology
[0002] At present, the smart meters in our country adopt two fixing methods, one is wall-mounted and the other is rail-mounted. The wall-mounted installation and replacement of the meter are inconvenient, and the wall-fixed meter needs to be connected to multiple Lines and wiring operations are complicated and need to be connected again when replacing the meter. In addition, the existence of multi-way terminals also requires relatively high structural design requirements for the meter.
The rail-type fixing method has the advantages of small size, easy installation, and easy networking, but it has higher requirements for the design of the circuit board of the meter and the design of the production tooling
