Electric energy meter connector using round internal expansion springs matched with multi-piece plugs

The utility model relates to an electric energy meter connector using round internal expansion springs matched with multi-piece plugs, which comprises a plurality of plugs, a bottom plate, and an electrical connection base, wherein a metal pipe good in conductivity is processed to form each plug, the upper part of each plug is processed into multiple metal sheets, the lower part is processed into an electrical connection end, and each plug is internally provided with a round internal expansion spring; the bottom plate has a plate-shaped structure whose shape is matched with that of the electric energy meter, edges of two opposite sides of the bottom plate protrude upwardly respectively and gradually to form guiding parts, and each guiding part is provided with an arc-shaped guiding and transition part; and the electrical connection base is fixed at the lower position of the bottom plate, and the lower end of each plug is fixed in the electrical connection base. The electric energy meter connector using round internal expansion springs matched with multi-piece plugs has the beneficial effects that when the electric energy meter is inserted, as the bottom plate and the guiding parts protruding at edges of the two sides and the guiding and transition surfaces have a guiding function, insertion is facilitated, a hanging buckle at the upper end of the back part of the electric energy meter is connected onto a protruding table at the upper end of the bottom plate after insertion in place, and the electric energy meter can be ensured to be accurately positioned.
