[0035] As shown in Figure 2 Further, the terminal seat structure further comprises:

[0036] The extension plate 2 is arranged on one side of the body 1 and extends away from the body 1. The extension plate 2 further increases the safe electrical distance between the body 1 and other electronic elements in the electric energy meter, and further guarantees the insulation isolation of the components.

[0037] It should be noted that, in the present scheme, the extension plate 2 has one, and the extension plate 2 is integrally formed with the body 1, and the extension plate 2 is formed by extending the side wall of the body 1 away from the first wiring terminal 107. As an alternative embodiment, the extension plate 2 can also extend from the top of the body 1, and the extending direction of the extension plate 2 can also be changed. In actual installation process, one end of the extension plate 2 abuts against the upper shell 6, and the isolation effect between the body 1 and the upper circuit board 8 is realized by abutting. The actual extension length of the extension plate 2 is set according to the internal space and actual needs.

[0038] Further, the first accommodating groove 101 is provided with a first solder needle guide hole 103, and the second accommodating groove 102 is provided with a second solder needle guide hole 104. The first solder needle guide hole 103 and the second solder needle guide hole 104 are arranged to facilitate the installation of the first wiring terminal 107 and the second wiring terminal 108.

[0039] It should be noted that the bottom surface of the first wiring terminal 107 and the second wiring terminal 108 is provided with a terminal solder needle, and the solder needle is fixed to the wiring terminal by riveting or welding.

[0040] Further, the first accommodating groove 101 is provided with a first solder needle guide hole 103, and the second accommodating groove 102 is provided with a second solder needle guide hole 104.

One end of the supporting column 5 is fixedly connected with the body 1 by welding or bonding, and the other end abuts against the electric energy meter.

[0050] It should be noted that, since the body 1 is connected with the electric energy meter through the mounting column 3 and the fixed clasp 4, if the mounting column 3 and the fixed clasp are arranged at a position that is too biased, for example, both are arranged at the bottom of the body 1 near the front side, which will result in poor stability of the body 1, by further increasing the supporting column 5, the stress on the body 1 is more uniform, and the overall stability is increased.
