[0027] Connecting mechanism 3 is arranged between electric energy meter main part 1 and communication module 2, to be used to dismount and assemble communication module 2;

[0028] In the embodiment, when communication circuit and communication module work appear heating, utilize heat conduction plate 22 to transfer the heat between the two, so that heat is transmitted to the surface of radiating fin 23 through heat conduction plate 22 and is radiated, and simultaneously, the radiating fan 25 in the inside of protective shell 24 works synchronously, and the heat between communication circuit and communication module is discharged to the inside of electric energy meter main part 1.

[0029] As Figure 2 And Figure 5As shown, the connection mechanism 3 includes two insertion holes 31 opened on the bottom of one side of the energy meter body 1. The communication module 2 is fixedly installed with two plug rods 32 on the side near the energy meter body 1. The plug rods 32 are inserted into the insertion holes 31, and limit holes 33 are opened on the side of the two plug rods 32 away from each other. Limiting members 34 are installed through the bottom of both sides of the energy meter body 1. The limiting members 34 include two mounting housings 341 installed through the bottom of both sides of the energy meter body 1. A piston plate 342 is slidably installed inside the mounting housing 341. One side of the piston plate 342 is fixedly installed with... A limiting block 343 is installed. One end of the limiting block 343 away from the piston plate 342 passes through the mounting housing 341 and is inserted into the limiting hole 33. A pull rod 344 is fixedly installed on the other side of the piston plate 342. One end of the pull rod 344 passes through the mounting housing 341 and extends to the outside of the mounting housing 341. A return spring 345 is fixedly sleeved on the surface of the pull rod 344. The two ends of the return spring 345 are fixedly connected to the piston plate 342 and the inner wall of the mounting housing 341, respectively. A handle 346 is fixedly installed on the end of the pull rod 344 located outside the mounting housing 341.

[0030] In this embodiment, when either the main body 1 of the electricity meter or the communication module 2 is damaged, the handle 346 is used to pull the pull rod 344 outward, which in turn moves the piston plate 342 and the limiting block 343 outward, causing the limiting block 343 to separate from the limiting hole 33, and the communication module 2 and the plug rod 32 to be pulled out of the plug hole 31, so that they can be replaced when either the main body 1 of the electricity meter or the communication module 2 is damaged.

[0035] Working principle: when the communication circuit and the communication module work and heat, the heat between the two is transferred by the heat-conducting plate 22, so that the heat is transmitted to the surface of the heat dissipation fin 23 for heat dissipation, at the same time, the heat dissipation fan 25 in the protective shell 24 works synchronously, and the heat between the communication circuit and the communication module is discharged from the inside of the electric energy meter body 1;

[0036] And when the electric energy meter body 1 and the communication module 2 are damaged individually, the handle 346 is used to pull the pull rod 344 outward, and the piston plate 342 and the limiting block 343 are driven to move outward, so that the limiting block 343 is separated from the limiting hole 33, and the communication module 2 and the insertion rod 32 are pulled out of the inside of the insertion hole 31, and after the electric energy meter body 1 or the communication module 2 is removed, the replaced electric energy meter body 1 or the communication module 2 is inserted into the inside of the insertion hole 31 by the insertion rod 32, and the insertion rod 32 is locked by the limiting piece 34, so that the single replacement can be completed.
