[0049] Embodiment Two

[0050] The electric energy meter provided by the embodiment has basically the same structure as that of Embodiment One, and only the differences will be described below. Figs. 4-6

[0051] Specifically, the shell 1 is provided with a plurality of vertical plates 12 distributed along the first direction, and the side surfaces of the vertical plates 12 located on both sides are provided with buckles 121, and the remaining vertical plates 12 located in the middle are provided with second recess grooves 122. When the fixing member 2 is connected with the shell 1, the main plate 21 is embedded into the second recess groove 122 on the vertical plate 12 located in the middle, and the two ends of the main plate 21 extend toward the vertical plates 12 located on both sides, and the buckles 121 on the vertical plates 12 located on both sides can be pressed on the main plate 21. In this structure, the limiting rib plate 22 is pressed on the guide plate 11, and the buckle 121 is pressed on the main plate 21, so as to limit the displacement of the fixing member 2 along the third direction, and the vertical plates 12 located on both sides limit the displacement of the fixing member 2 along the first direction, and the second recess groove 122 limits the displacement of the fixing member 2 along the second direction.

[0052] When the fixing member 2 is installed, the main plate 21 only needs to be pressed to embed the main plate 21 into the second recess groove 122, and at the same time, the two ends of the main plate 21 extrude the buckles 121, so that the vertical plates 12 located on both sides are elastically deformed, and after the main plate 21 is in place, the vertical plates 12 located on both sides restore the deformation, and the buckles 121 are pressed on the main plate 21. In order to facilitate the main plate 21 to pass through the buckle 121 more smoothly, the upper end of the buckle 121 away from the bottom of the shell 1 is provided with a chamfer, so that when the main plate 21 is pressed, the chamfer of the buckle 121 can make the main plate 21 move more smoothly.

[0053] Optionally, each mounting position includes two surrounding plates 13 distributed along the first direction, the guide plate 11 is limited between the corresponding two surrounding plates 13, and at least two surrounding plates 13 in the plurality of mounting positions are provided with extension portions 131. The side of the main plate 21 facing the surrounding plate 13 is provided with at least two second limiting notches 211 distributed along the first direction, and the two extension portions 131 can be respectively and correspondingly inserted into the two second limiting notches 211. This structure makes the installation of the fixing member 2 more stable.

[0054] In this embodiment, the shell 1 is provided with two spaced-apart baffles 14 along the first direction, and the PCB plate 3 is arranged between the two baffles 14.

[0055] Optionally, the side of the main plate 21 away from the limiting rib plate 22 is provided with a plurality of supporting ribs 23, and the PCB plate 3 can be supported on the plurality of supporting ribs 23 and clamped between the two baffles 14 when installed. By providing the supporting ribs 23 on the side of the main plate 21 away from the limiting rib plate 22, the installation height of the PCB plate 3 can be limited.​

[0056] Further, in order to further limit the PCB 3, the main plate 21 away from the side of the limiting rib plate 22 is also provided with a limiting buckle 24, and the PCB 3 is provided with a limiting hole. When the PCB 3 is installed, the limiting buckle 24 can be clamped in the limiting hole. Through the clamping of the limiting buckle 24 in the limiting hole, and cooperating with the supporting rib 23, the displacement of the PCB 3 along the third direction can be limited, and the installation of the PCB 3 is more stable.

[0057] Specifically, the limiting buckle 24 includes a connecting part 241 and two clamping parts 242 spaced apart on the connecting part 241. The connecting part 241 is fixedly connected with the main plate 21, and the two clamping parts 242 are provided with clamping bosses 2421 on the side opposite to each other. When installing the PCB 3, the limiting hole of the PCB 3 is opposite to the clamping part 242 and the PCB 3 is pressed. The limiting hole of the PCB 3 abuts against the two clamping bosses 2421 to make the two clamping parts 242 deform and approach each other. When the two clamping bosses 2421 pass through the limiting hole, the two clamping parts 242 restore the deformation due to their own elasticity, and the two clamping bosses 2421 can be pressed on the side of the PCB 3 away from the supporting rib 23 to prevent the limiting hole of the PCB 3 from being pulled out of the clamping part 242.

[0058] In order to make the limiting hole of the PCB 3 more smoothly clamped into the limiting buckle 24, the upper end of the clamping boss 2421 away from the connecting part 241 is provided with a chamfer, so that the installation of the PCB 3 is more smooth.

[0059] Further, the fixing part 2 further comprises a plurality of reinforcing plates 25 corresponding to the limiting rib plate 22. Each reinforcing plate 25 connects the main plate 21 and the corresponding protruding rib 221 on the limiting rib plate 22. This structure further improves the structural strength of the limiting rib plate 22.

[0060] Optionally, the limiting rib plate 22 is provided with a trapezoidal structure. From the limiting rib plate 22 to the main plate 21, the cross-sectional size of the limiting rib plate 22 gradually increases. This structure sets the limiting rib plate 22 to a trapezoidal structure, which can enhance the connection strength of the limiting rib plate 22 and the main plate 21.

[0061] Optionally, the fixing part 2 is made of plastic. By processing the fixing part 2 with plastic material, the fixing part 2 has no risk of salt spray corrosion and has a longer service life.
