Combination module for plugging and unplugging electrical connections of smart watt-hour meters

Abstract

The invention discloses a combined module for plug electric connection of an intelligent electricity meter. The combined module comprises a lower shell, a plurality of wiring terminals arranged on the lower shell, and banana pins respectively connected with the wiring terminals, wherein a plurality of grooves are formed in the lower shell, the lower parts of the banana pins are matched and fixed with the grooves, flat parts are horizontally arranged at the tail ends of the banana pins, the flat parts penetrate through the wiring terminals and are connected with the wiring terminals by pressure welding, dual elastic sleeving heads are connected to the front ends of the banana pins, and are of a front and back dual-lantern-shaped structure along the length direction per se, and the dual elastic sleeving heads are inserted with the electricity meter. According to the invention, the combined module for plug electric connection of the intelligent electricity meter has the advantages that installation procedures are simple and convenient, requirement on the technical level of an installation worker is low, time required by installation is greatly shortened, safety coefficient is high, connection nodes among internal components are few, the neat, stable and reliable effects are achieved, connection is stable, and potential safety hazards caused by short circuiting, touch and the like are avoided.

Description

technical field [0001] The invention relates to a plug-in electrical connection combination module, in particular to a plug-in electrical connection combination module for an intelligent watt-hour meter. Background technique [0002] With the construction of smart grid, smart meters have been fully promoted in China, and the collection of electricity consumption information and data mining based on smart meters have also been carried out one after another; smart meters are an important link for the construction of smart electricity. The amount of smart meters is large and the area is wide, and the workload of installation and maintenance is extremely huge. [0003] The traditional meter box still adopts the design of connecting wires that directly compress the wires with screws. This connection method has the following disadvantages: [0004] 1. The installation process of the connection line is relatively complicated, and the requirements for the installation workers are h...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the complicated installation process of connecting wires in the prior art, high requirements for installation workers, time-consuming and labor-intensive installation, especially the limited technical level of agricultural electricians, so accidents often occur; the safety performance is low, and the traditional way of wiring Irregularities can easily lead to inaccurate measurement and frequent burning of the meter. Because the connecting wires may be short-circuited or touched, they may be charged during work, not tightened tightly, and the temperature will rise due to false connections. Therefore, there are potential safety hazards in installation and operation. Insufficient, it provides a simple and convenient installation process, lower requirements on the technical level of installation workers, greatly reducing the time required for installation; high safety factor, less connection nodes between internal components, clean, stable, reliable, stable and unstable connection Combination modules for plugging and unplugging electrical connections of smart watt-hour meters that may cause potential safety hazards due to short-circuiting and touching
