When the protective cover 200 is covered on the shell body 100, along the length direction of the shell body 100, the opposite sides of the inner circumferential surface of the protective cover 200 are connected with the sides of the corresponding second baffles 120 away from the second baffles 120 on the opposite side, respectively, so as to prevent water or dust from entering the containing space from the connecting position between the first plate body 211 and the bottom wall surface 1011, and to improve the sealing performance of the electric energy meter.

[0076] In the embodiment, along the width direction of the shell body 100, the water retaining groove 111 is arranged on the side of the first baffle 110 away from the second sealing structure. Along the length direction of the first baffle 110, the water retaining groove 111 penetrates through the first baffle 110, which can timely drain the accumulated water in the water retaining groove 111, so as to reduce the situation that water seeps into the containing space from the connecting position between the first baffle 110 and the baffle 220.

[0077] It should be noted that when water passes through the connecting position between the protective cover 200 and the containing groove 101, the water first enters the water retaining groove 111, and the water in the water retaining groove 111 can be drained from both ends of the water retaining groove 111, which can timely drain the accumulated water in the water retaining groove 111, so as to reduce the situation that water seeps into the containing space from the connecting position between the first baffle 110 and the baffle 220.

[0078] Reference Figure 11 , Figure 12 , Figure 12 For Figure 11A local enlarged view of the middle G part. As shown in the figure, the side of the shell body 100 away from the bottom wall surface 1011 is provided with at least one opening 112. For example, the opening 112 is configured with four openings 112, which are arranged side by side and spaced apart along the length direction of the first barrier strip 110. The opening 112 is in communication with the water retaining groove 111, and can timely drain the accumulated water in the water retaining groove 111, so as to reduce the case of water seeping into the accommodation space from the connecting position between the first barrier strip 110 and the third plate body.

[0079] It should be noted that the length direction of the first barrier strip 110 is consistent with the length direction of the boss, which is not described here.

[0080] Of course, in another specific embodiment, the number of openings 112 can also be one, two or three, etc., which is not limited here.

The length direction of the positioning strip 204 is arranged along the direction from the first plate body 211 to the opposite first plate body 211. The positioning strip 204 is located on the side of the second sealing strip 203 close to the baffle 220. When the protective cover 200 is arranged on the shell body 100, the positioning strip 204 can abut against the communication module 300, so that the communication module 300 can be stably installed in the accommodation space, and the installation of the communication module 300 can be facilitated.

[0082] It should be noted that the bottom wall surface 1011 is provided with a positioning block arranged opposite along the direction from the first plate body 211 to the opposite first plate body 211. The positioning block is provided with a positioning groove. The end of the communication module 300 close to the bottom wall surface 1011 is accommodated in the positioning groove and can abut against the side wall of the positioning groove. The positioning strip 204 can limit the movement of the communication module 300 in the direction of exiting the positioning groove, so that the communication module 300 can be stably installed in the accommodation space, and the installation of the communication module 300 can be facilitated.

[0083] It should be noted that the cover 140 is provided with a connecting assembly 150. The connecting assembly 150 is located in the accommodation space. The connecting assembly 150 is provided with a mounting groove 151 for mounting the battery 500. The battery 500 is electrically connected with the circuit board 400, so that the circuit board 400 can control the working of the communication module 300. Moreover, since the mounting groove 151 is located outside the accommodation space, the space occupied by the connecting assembly 150 on the circuit board 400 can be reduced.

[0084] For example, the connecting assembly 150 comprises a first clamping piece 152 and a second clamping piece 153 arranged oppositely, the first clamping piece 152 and the second clamping piece 153 enclose a mounting groove 151, and the first clamping piece 152 and the second clamping piece 153 can abut against the outer circumferential surface of the battery 500, so that the battery 500 can be conveniently mounted and fixed.
