In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0025] like Figure 1-4 It is a structural schematic diagram of a 4G communication DC energy meter in a preferred embodiment of the utility model. In this embodiment, a 4G communication DC energy meter includes an upper cover 1 and a base 2 arranged at the bottom of the upper cover 1, a mounting cavity 21 is opened in the base 2, and a mounting position 11 is opened on the top of the upper cover 1, and a connecting column 15 is fixedly connected to the top of the upper cover 1. At the same time, a connecting position 12 is opened on the mounting position 11, and the connecting position 12 is communicated with the mounting cavity 21. A 4G communication module 13 is plugged in the connecting position 12, so that the 4G communication module 13 and the mounting cavity 21 can be connected. In order to connect the internal components, a rotation position 14 is provided at the top of the upper cover 1 on one side of the installation position 11, and a protective cover 3 is rotatably connected to the rotation position 14 to protect the 4G communication module 13.
