[0023] The bottom box 9 has a back plate and side plates, and an assembly portion is formed on the back side of the back plate, and an electric meter assembly structure is connected to the assembly portion in a detachable assembly manner. The electric meter assembly structure is a hook structure, an insertion structure or a threaded assembly structure 12.

[0025] In this embodiment, a plurality of assembly columns 10 for assembly are formed on the bottom surface of the component assembly cavity 11, and the corresponding assembly partition 2 is formed with assembly seats 13 on both sides for matching with the assembly columns 10. The assembly seats 13 match with the corresponding assembly columns 10 so that the assembly partition 2 can cover the lower surface of the component assembly cavity 11 through the assembly seats 13, and be fastened on the assembly seats 13 and the assembly columns 10 by screws.

[0026] The area of ​​the assembly partition 2 in the assembly plane corresponding to the component assembly cavity accounts for 40%, so that an area not covered by the assembly partition 2 is reserved on the upper part of the component assembly cavity 11.

[0027] The assembly partition 2 has a plate surface parallel to the back plate in the base box 9. When assembled on the assembly column 10 in the component assembly cavity 11 through the assembly seat 13, the plate surface of the assembly partition 2 is flush with the surface of the component assembly cavity 11; and there are three module assembly positions on the surface of the assembly partition 2. The left module assembly position and the middle module assembly position of the assembly partition 2 among the three module assembly positions are respectively fixed in position by the buckle 14 and the assembly strip 15 as a detachable assembly structure for the corresponding modules; and the right module assembly position among the three module assembly positions is directly formed with a ready-made communication enhancement module 16.

[0028] The open surface of the bottom box 9 corresponding to the volume cavity is covered by a cover 3, and the cover 3 is formed with a convex portion 5 at the covering position corresponding to the bottom box 9 where the partition 2 is assembled, and the cover 3 is respectively formed with an upper covering surface 4 and a wiring position panel at the upper and lower parts of the convex portion 5.

[0029] In this embodiment, the component assembly cavity 11 is used as an assembly space, mainly for assembling fixed components that realize the basic functions of the electric meter, and a second assembly space is separated between the surface of the assembly partition 2 and the outer protrusion 5 of the cover 3, and the assembly space is used to install the expansion module (excluding the installed communication enhancement module 16, there are two module assembly positions), and the corresponding expansion module can be arranged on the shell The corresponding fixing structure is matched with the buckle 14 and the assembly clip 15 to realize the assembly and fixation of the position. The corresponding expansion module communicates with the fixed components in the component assembly cavity 11 through contacts or wiring harnesses.

[0030] The upper cover surface 4 is in the same plane as the assembly partition 2 after the transfer, and covers and seals the component assembly cavity 11 together with the assembly partition 2 on the upper part of the assembly partition 2; the surface of the upper cover surface 4 is covered and sealed by the auxiliary cover 1, and the auxiliary cover 1 has an outer surface flush with the outer protrusion 5, so that a volume space is left between the auxiliary cover 1 and the upper cover surface 4. The volume space can be used as an assembly space for functional units or a storage space for sundries, and the purpose can be selected according to actual needs.
