The substrate 1 is provided with a plurality of circular holes 3 for external wires to pass through and connect to the electric energy meter, and the circular holes 3 are arranged in an array along the extension direction of the substrate 1, and the positioning plate 2 is provided with an avoidance groove 21 for assisting the heat dissipation of the electric energy meter.

[0027] The above specific improvements are: Figure 1 and Figure 2 As shown, compared with the prior art, the electric energy meter is arranged on the substrate 1 and the positioning plate 2. When the electric energy meter needs to be replaced or repaired, the substrate 1 and the positioning plate 2 are flipped counterclockwise to open the contact assembly 4, thereby putting the electric energy meter in a power-off state. In this way, when replacing the electric energy meter, there is no need to remove the electric energy meter, and only the substrate 1 and the positioning plate 2 need to be flipped. Through the arrangement of the substrate 1 and the positioning plate 2, the electric energy meter can be quickly opened and closed by rotation. The electric energy meter will generate more heat during operation. When the heat cannot be dissipated, it will affect the service life of the electric energy meter. Through the arrangement of the avoidance groove 21, the electric energy meter can be assisted in heat dissipation, thereby effectively protecting the electric energy meter.

[0031] The above specific improvements are: Figure 4As shown, the contact assembly 4 includes a connecting rod 41 and a connecting shaft 42 that can contact or separate from the connecting rod 41. When the connecting rod 41 and the connecting shaft 42 are in contact, the electric energy meter is in a power-on state. When the connecting rod 41 and the connecting shaft 42 are separated, the electric energy meter is in a power-off state. When installing the connecting rod 41 and the connecting shaft 42, it is necessary to first insert the connecting rod 41 upward from the bottom of the circular hole 3 so that the lower end of the connecting rod 41 is embedded in the extension column 11, and then the connecting shaft 42 is adapted to be connected to the connecting rod 41. The side of the connecting shaft 42 facing away from the connecting rod 41 will be connected to the incoming wire or the outgoing wire of the electric energy meter. When the connecting rod 41 and the connecting shaft 42 are separated, the current on the connecting shaft 42 will no longer pass through the connecting rod 41 to reach the electric energy meter.

[0032] On the basis of the above embodiment: the connecting rod 41 is provided with a groove 5 for the connecting shaft 42 to be inserted and a rotating shaft passing through the groove 5, the connecting shaft 42 is provided with a rotating groove 6 which is buckled with the rotating shaft, and the rotating groove 6 is provided with an opening 61 for the connecting shaft 42 to be separated from the connecting rod 41.

When the contact assembly 4 is closed, the first connecting piece 421 and the second connecting piece 422 are respectively attached to the two sides of the connecting block 7. When the contact assembly 4 is opened, the base plate 1 and the positioning plate 2 rotate, which will drive the connecting rod 41 to rotate, thereby separating the connecting rod 41 from the connecting shaft 42.

[0036] On the basis of the above embodiment: a gripping block 8 for human hand gripping is arranged on the side of the positioning plate 2 facing away from the base plate 1, and an inclined block 81 is arranged on the gripping block 8, and a circular inclined surface 82 for contacting with fingers is arranged on the inclined block 81.
