Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] During specific implementation: As Figures 1-5 shown, a low-voltage combined wiring box for an electric energy metering device includes: a box body 1, a wiring mechanism is arranged inside the box body 1, a cover plate 101 is arranged on the top of the box body 1, two screws 102 are fixedly connected to the top of the box body 1, through holes corresponding to the screws 102 are formed on the surface of the cover plate 101, and nuts 103 are arranged on the surfaces of the screws 102; a lead wire structure 2, the lead wire structure 2 is arranged on the surface of the box body 1; wherein, the lead wire structure 2 includes a plurality of first insulating rings 202 arranged on the surface of the box body 1, wire grooves 201 are evenly distributed on the surface of the box body 1, and the first insulating rings 202 are embedded in the inner walls of the wire grooves 201;

[0022] The setting of the wire grooves 201 can facilitate the wire to pass through the box body 1 after being connected to the wiring mechanism. The wiring mechanism is a structural component used for connecting wires in the combined wiring box of the electric energy metering device, which is a well-known technology to those skilled in the art and will not be elaborated here.

[0023] As Figure 2 、 Figure 4 and Figure 5 shown, the lead wire structure 2 further includes an insertion block 203 fixedly connected to the bottom of the cover plate 101 and matching with the wire groove 201. A groove is formed at the bottom of the insertion block 203, a second insulating ring 204 is arranged on the inner wall of the groove, the cross-sections of the first insulating ring 202 and the second insulating ring 204 are both semi-circular, and the radii of the first insulating ring 202 and the second insulating ring 204 are equal. Two symmetrically distributed insulating gaskets 205 are fixedly connected to the surface of the second insulating ring 204. The aperture of the insulating gasket 205 is smaller than the aperture of the second insulating ring 204. An installation cavity is formed inside the insertion block 203. A sliding plate is slidably connected to the inner wall of the installation cavity. A connecting rod 207 is fixedly connected to the bottom of the sliding plate. The other end of the connecting rod 207 penetrates out of the insertion block 203 and is fixedly connected to the surface of the first insulating ring 202. A spring 206 is fixedly connected to the top of the sliding plate, and the other end of the spring 206 is fixedly connected to the inner wall of the installation cavity.

[0024] When installing the cover plate 101, it can be guided through the through-hole by the screw 102, improving the installation accuracy. During the installation of the cover plate 101, the insertion block 203 can be driven to insert into the inside of the wire groove 201. At this time, the first insulating ring 202 and the second insulating ring 204 can clamp the wire, and seal the gap between the wire and the wire groove 201 and the groove, reducing the situation of external dust and impurities entering the inside of the box body 1.

The setting of the anti-slip lines 105 can facilitate the rotation of the connection shell 104. Compared with the traditional method that requires a cross screwdriver for tightening, this method is more convenient to operate.

[0028] When the utility model is in use, the setting of the wire groove 201 can facilitate the wire to pass through the box body 1 after being connected to the wiring mechanism. When installing the cover plate 101, it can be guided through the through-hole by the screw 102, improving the installation accuracy. During the installation of the cover plate 101, the insertion block 203 can be driven to insert into the inside of the wire groove 201. At this time, the first insulating ring 202 and the second insulating ring 204 can clamp the wire, and seal the gap between the wire and the wire groove 201 and the groove, reducing the situation of external dust and impurities entering the inside of the box body 1. The setting of the spring 206 can drive the second insulating ring 204 to be close to the first insulating ring 202 through the sliding plate and the connecting rod 207, improving the connection effect between the two and further improving the sealing effect.
