AI Technical Summary

Technical Problem

In existing anti-detachment structures for smart energy meter circuits, the sidewalls of the clamping frame are prone to permanent deformation or material aging, resulting in a decrease in clamping force. Furthermore, the ability to adapt to changes in cable diameter is limited, and the sealing performance deteriorates after repeated disassembly and reassembly, affecting the reliability of use.

Method used

The device employs a combination design of a limit plate, locking assembly, arc-shaped clamp, and protective cover. A knob drives the worm gear to rotate the lead screw, enabling the arc-shaped clamp to extend and hold. Combined with the elastic engagement of the locking pin and the elastic metal sheet, it achieves quick locking and flexible adjustment of clamping force, avoiding interference fit and ensuring long-term stability and convenient operation.

Benefits of technology

It achieves flexible and adaptable clamping of cables of different diameters, avoids the aging and failure of elastic materials, maintains a long-term stable clamping force, improves the ease of operation and electrical safety protection level, and ensures the reliability and safety of electricity meter wiring.

Abstract

The utility model provides an intelligent electric energy meter circuit anti-drop structure, and relates to the technical field of intelligent electric energy meters, the intelligent electric energy meter circuit anti-drop structure comprises an electric energy meter main body, a wiring groove is arranged below the front surface of the electric energy meter main body, a limiting plate is fixedly installed below the interior of the wiring groove, and a plurality of limiting holes are formed in the limiting plate; and a locking assembly is arranged on the inner wall of the limiting hole. Through cooperative use of the electric energy meter main body, the limiting plate, the wiring groove, the limiting hole, the hidden groove, the arc-shaped clamp, a fixed groove, a movable block, a connecting block, a knob, a screw rod, a worm, a worm gear and a sliding groove, the knob drives the worm and the worm gear to drive the screw rod to rotate, so that the movable block pushes the arc-shaped clamp to extend out of the hidden groove through the connecting block; and the wire is rigidly clamped in the limiting hole. According to the structure, the problem of aging failure caused by long-term compression of the elastic material is avoided, the clamping force can be flexibly adjusted, and the structure can adapt to cables with different diameters.
