Meter tail plug for electric energy meter

Abstract

The invention relates to a meter tail plug for an electric energy meter. The meter tail plug includes a plurality of contact pin devices and a protective box; each contact pin device includes copper columns and cylindrical insulation sleeves that wrap one ends of the copper columns; the tail ends of the insulation sleeves are provided with wiring bolts connected with the copper columns and connecting wires arranged on the wiring bolts; and the protective box includes an upper cover and a lower cover which are connected through a rotating shaft, after the upper cover and the lower cover are closed oppositely, a plurality of parallel contact pin slots used for clamping the contact pin devices are formed inside, the upper ends of the contact pin slots are provided with contact pin holes used for the copper column to penetrate out, the lower ends are provided with wire holes used for the connecting wires to penetrate out. The meter tail plug for the electric energy meter saves both time and labor, is simple and convenient to operate, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a matching plug for the meter tail of an electric energy meter. Background technique [0002] The installation of metering electric energy meters is a very meticulous work. For many years, the method of crimping copper wires in the crimping holes at the end of the meter has been used for installation, which is labor-intensive, time-consuming, and inefficient; and this method is easy to connect wrong wires during the installation process, resulting in Metering is inaccurate. In addition, when installing and disassembling the electric energy meter for many times, the compression screw will break the copper wire core, and the wire core needs to be stripped again. In addition to the screwdriver, the tools used include wire strippers, needle-nose pliers and other special electrician tools. The whole process is time-consuming and labor-intensive.
