During the connection process, the copper busbar 31 is embedded in the support plate 4 to replace the wire connection method. In this way, when disassembling the metering component 2, only the metering component 2 and the conductive extension bar 32 need to be disassembled and replaced with a new metering component 2, which greatly simplifies the conductive structure. After the installation is completed, there are no exposed conductive parts, which can make the entire metering box look neater and is superior to the prior art, avoiding the phenomenon of aging of the outer shell of the outgoing cable after long-term use.

[0029] On the basis of the above embodiment: the metering component 2 is composed of a plurality of electric energy meters, the shell 1 is provided with a control area 11 for loading a main switch 14 and a metering area 12 for carrying a plurality of electric energy meters, a partition plate 13 is provided between the control area 11 and the metering area 12, one end of the copper busbar 31 passes through the partition plate 13 and is connected to the main switch 14, and the other end is connected to the electric energy meter.

[0032] The above specific improvements are: Figure 3 and Figure 4 As shown, the support plate 4 includes a base plate 41 and a positioning plate 42. The base plate 41 is fixedly connected to the inner wall of the shell 1 at the position of the metering area 12. The positioning plate 42 is fixed above the base plate 41. The two are connected by fastening nails. When the electric energy meter needs to be replaced, the fastening nails between the positioning plate 42 and the base plate 41 can be removed, and the positioning plate 42 can be removed separately. Then, the electric energy meter on the positioning plate 42 can be repaired and replaced. The copper busbar 31 is pre-buried between the positioning plate 42 and the base plate 41. The conductive extension strip 32 at the end of the copper busbar 31 passes through the through slot 43 on the positioning plate 42, thereby connecting with the electric energy meter to realize power supply.

[0033] On the basis of the above embodiment: a positioning groove 5 for clamping the copper busbar is provided on the side of the base plate 41 facing away from the positioning plate 42, a wrapping plate 51 for wrapping the copper busbar is provided in the positioning groove 5, and the wrapping plate 51 is connected to the base plate 41 by fastening nails.
