[0028] In this embodiment, the meter body 3 is mainly used for electricity metering. It removes the security authentication, remote communication and other modules of the traditional meter, and then concentrates the security authentication, remote communication and other modules in the meter management terminal 2 of the meter system. Multiple meter bodies 3 share the same meter management terminal 2.

Specifically, the shell includes an upper cover, a bottom cover and an installation frame. A first accommodating cavity is provided between the upper cover and the installation frame, and a second accommodating cavity is provided between the bottom cover and the installation frame. The electric meter body 3 and the electric meter management terminal 2 are both installed in the first accommodating cavity, and a connecting cable is provided in the second accommodating cavity.
[0032] Furthermore, in this embodiment, almost all the connection cables in the electric meter system are located in the second accommodating cavity. In order to avoid the connection cables from being interlaced and causing inductance, in this embodiment, a plurality of installation guide bar assemblies 4 are provided on one side of the second accommodating cavity in the installation frame, and a plurality of cable clamps are provided on the installation guide bar assemblies 4. The cable clamps and the installation guide bar assemblies 4 are connected by snap-fit. Figure 4 As shown in FIG. 1 , the cable clamp comprises a cable fixing hole 501 and a mounting clamp block 502.
