[0023] Example

[0024] The present embodiment provides an electric energy meter box with a circuit structure in which an electric energy meter can be replaced with power on. The electric energy meter includes a base 1 and a flip plate 2 arranged above the base 1. A meter body 3 is arranged on the flip plate 2. The circuit structure includes an inlet terminal 31 and an outlet terminal 32 connected to the meter body 3 to enable the meter body 3 to be energized. A copper piece 33 is connected to the flip plate 2. An opening and closing structure is arranged between the meter body 3 and the inlet terminal 31. The meter body 3 has an opening state and a closing state. In the opening state, the inlet terminal 31 and the outlet terminal 32 are in contact with the copper piece 33; in the closing state, the inlet terminal 31 and the outlet terminal 32 are in contact with the meter body 3.

[0025] The above specific improvements are: Figure 1-Figure 3 As shown, compared with the prior art, when the meter body 3 needs to be repaired, it is only necessary to rotate the flip plate 2 counterclockwise, and then the opening and closing mechanism will open the switch, and then the incoming line terminal 31 and the outgoing line terminal 32 will contact the copper piece 33 to form power. The copper piece 33 is arranged behind the flip plate 2. When the incoming line terminal 31 and the outgoing line terminal 32 complete the contact with the copper piece 33, the meter body 3 is powered off, and through the overlapping effect of the copper piece 33, the entire circuit can continue to be powered on. This is better than the prior art. When the circuit of the meter body 3 is switched for maintenance, residents can still use electricity normally.

[0026] On the basis of the above embodiment: the opening and closing structure includes a connecting rod 4 arranged on one side of the incoming line terminal 31 or the meter body 3 and a connecting shaft 41 arranged on the other side and rotatably connected to the connecting rod 4.

[0027] The above specific improvements are: Figure 3 and Figure 4 As shown, the opening and closing structure includes a connecting rod 4 and a connecting shaft 41. When opening the switch, the connecting shaft 41 rotates and separates from the connecting rod 4. At the same time, the connecting shaft 41 and the incoming line terminal 31 come into contact with the copper part 33, so that the meter body 3 is in a power-off state, while the connecting shaft 41, the incoming line terminal 31, the copper part 33 and the outgoing line terminal 32 are energized, so that the entire circuit continues to be energized.

[0028] On the basis of the above embodiment: the connecting shaft 41 is arranged on the incoming line terminal 31, the connecting rod 4 is arranged below the meter body 3, the connecting rod 4 is provided with a rotating shaft which is inserted into a groove for the connecting shaft 41 and passes through the groove, the connecting shaft 41 is provided with a rotating groove 42 which is buckled with the rotating shaft, and the rotating groove 42 is provided with an opening 43 for the connecting shaft 41 to be separated from the connecting rod 4.

Here, the opening and closing structure on the incoming terminal 31 is taken as an example. The connecting shaft 41 is fixedly set on the incoming terminal 31, and the connecting rod 4 is set under the meter body 3. When the opening and closing structure switches from the closed state to the open state, the connecting shaft 41 will rotate along the direction set by the rotating groove 42, and come out from the opening 43, thereby playing an opening role.

[0030] On the basis of the above embodiment: the connecting shaft 41 includes a first connecting piece 411, a second connecting piece 412 and an arc-shaped piece 413 arranged in parallel between the first connecting piece 411 and the second connecting piece 412, and an extension block 5 is arranged below the connecting rod 4. In the closed state, the first connecting piece 411 and the second connecting piece 412 are respectively located at the two ends of the extension block 5.

[0031] On the basis of the above embodiment: the incoming line terminal 31 includes a power-on terminal 311 attached to the connecting shaft 41 and a connecting terminal 312 perpendicular to the power-on terminal 311, and the power-on terminal 311 and the connecting terminal 312 are arranged in an "L" structure. When the meter body 3 is in the open state, the side wall of the connecting terminal 312 is in contact with the copper part 33.

[0032] The above specific improvements are: Figure 3 The connecting shaft 41 includes a first connecting piece 411 and a second connecting piece 412 arranged in parallel, an arc-shaped piece 413 is arranged between the first connecting piece 411 and the second connecting piece 412, a connecting block is arranged under the connecting rod 4, and the first connecting piece 411 and the second connecting piece 412 are arranged on both sides of the extension block 5, thereby effectively increasing the contact surface between the connecting rod 4 and the connecting shaft 41.
