[0002] With the development of society and the improvement of power safety regulations, users have put forward higher requirements for the safety and reliability of power supply facilities. Electricity meter boxes are widely used in rural and urban civil, commercial, factory and other fields for safe electricity management. Especially in recent years, with the accelerated pace of urbanization in my country, the State Grid has continued to invest in power infrastructure. In terms of electricity management, the demand for intensive electricity management is growing. The multi-meter single-phase electricity meter box is currently a commonly used solution. However, at present, the main switch installation design of most multi-meter boxes is still directly connected with wires. Use wires to connect the main switch,
[0003] When the main switch is damaged, the electrical staff needs to cut off the power supply to the branch box in front of the electricity meter box to safely replace it. However, this will cause power outages for a large number of other adjacent users. The replacement is manual, with many connections and frequent false connections. In addition, a large amount of wire materials is wasted when making the connecting wires, making replacement of the main switch difficult, inefficient, and non-standard. Summary of the Invention

The main switch incoming line connector is composed of three copper bars and three quick connectors. One end of the three copper bars is connected to the wires entering the meter box, and the other end is connected to the copper connector through the quick connector. The main switch outgoing line connector is composed of three copper bars and three quick connectors. One end of the three copper bars is connected to the main switch copper connector of the meter box, and the other end is connected to the metering meter in the meter box through the copper bar. The main switch fixing and quick disassembly device is composed of two upper and lower limiter quick disassembly kits and two upper and lower sets of copper connectors. The function of the limiter quick disassembly kit is to realize manual operation and quick disassembly of the main switch, and the upper and lower sets of copper connectors are fixed by limiting grooves to realize connection with the quick connectors on both sides of the main switch incoming and outgoing lines to achieve electrical quick connection.
[0006] The three quick connectors and two sets of upper and lower copper connectors are connected by coupling of yin and yang cylinders that are not limited to cylindrical shapes; the yin and yang cylinder coupling connection design satisfies the requirements that the yin cylinder is larger at the top and smaller at the bottom, and the yang cylinder is smaller at the top and larger at the bottom, so as to achieve fast, safe and convenient coupling electrical connection.
[0007] The upper and lower sets of copper connectors are connected to the main switch and are fixedly connected through the connection ports by welding or a connector structure.
[0008] It also includes an electrical zero line loop passing through a copper busbar, and the electrical zero line loop is fixedly connected to the wire entering the meter box and the zero line of the household wire loop through the copper busbar.
[0009] Beneficial effects of the present invention: The present invention modularizes the main switch connection method, connects the household wires to the main switch through modular plug-in connections, and connects the main switch to the household wires in the box. This method can achieve quick plug-in connection, which has the advantages of better safety, economy, and easy operation and maintenance compared with the previous wiring installation of the main switch, and can better meet the needs of intensive power management.
