Technical Field
The invention relates to the technical field of power equipment, in particular to a wiring terminal of an electric energy meter and the electric energy meter comprising the wiring terminal.
Background
An electric energy meter is a meter for measuring electric energy, which can be electrically connected to a circuit through a connection terminal. Generally, when connecting, one end of the wire terminal is stripped from an exposed metal end of an insulating layer, the metal end is inserted into a plug hole of a wiring terminal, and the wire is crimped by a screw arranged on the side wall of the plug hole, so that the electrical connection and the mechanical connection between the wire and the electric energy meter are realized. However, in actual operation, when the electric wire is plugged, the electric wire is not plugged to the bottom of the plugging hole, so that poor connection is caused, or a meter burning accident occurs in the use process, so that great hidden dangers exist in equipment safety and electric power operation safety.
Therefore, a novel connection terminal of an electric energy meter is needed to ensure connection soundness and improve use safety.
