Modularized electric energy metering box

The invention belongs to the technical field of electric energy metering boxes, and particularly relates to a modular electric energy metering box, which comprises a box body, an electric meter, a breather pipe, a trap lamp, an electrified wire, an insect collecting pipe and a storage box, when insects enter a first cavity, the trap lamp emits ultraviolet rays for attracting the insects, the insects are driven by phototropic instinct to approach a light source, and the insect collecting pipe is driven by the electricity meter to emit light. When the insects approach the trap lamp, the insects firstly make contact with the electrifying wire, after the insects make contact with the electrifying wire, due to the fact that the bodies of the insects are very small, the insects can be quickly coked, the coked insects fall onto the second plate and then enter the insect collecting pipe along the second plate, and finally the insects fall into the storage box along the insect collecting pipe. In this way, the problem
