Abstract
The invention provides a no-shutdown meter changing structure of an insertion-typed electric energy meter, consisting of an electric energy meter and a meter base; wherein, the electric energy meter comprises a meter shell, a plug, a metering mechanism, a flange and an insertion rod; the meter base comprises a base body, a cover plate, a hole-shaped spring, a convex edge, an inlet wire, an outlet wire, an upper spring leaf and a lower spring leaf. After the electric energy meter is inserted into the meter base, the insertion rod passes through a through hole at the upper edge of the upper spring leaf and pushes the upper edge of the lower spring leaf to be open; the power is turned on by the electric energy meter; and after the electric energy meter is pulled out, the power is turned on by the upper spring leaf and the lower spring leaf. The no-shutdown meter changing structure solves the problem that the insertion-typed electric energy meter is changed without turning off the power.
