[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-6 , an intelligent electric meter with firm wiring of the present utility model includes an electric meter body 1. A slot 2 for inserting a wire is provided at the lower part of the electric meter body 1. The slot 2 is vertically arranged. Coaxial threaded holes 8 are provided on the front side wall and the rear side wall of the slot 2. A compression screw 7 is arranged in the threaded hole 8 on the front side wall. The diameter of the rear end of the compression screw 7 is smaller than that of the front end. A conductive sheet 6 is arranged on the rear side wall of the slot 2; a connection terminal is arranged at the end of the wire, and a through hole 11 matching the front end of the compression screw 7 is arranged on the connection terminal.
[0020] In the specific implementation of the present utility model, a display screen 12 is provided at the upper part of the front side of the electricity meter body 1, and an indicator light 13 is provided below the display screen 12. The side of the electricity meter body 1 with the display screen 12 is the front side, and the opposite side is the rear side. The threaded hole 8 is arranged horizontally, and the threaded hole 8 on the front side wall of the slot 2 is communicated with the slot 2. The pressing screw 7 is threadedly connected in the threaded hole 8, and the head of the pressing screw 7 is outside the threaded hole 8. A counterbore can also be provided. The head of the pressing screw 7 is provided with a cross slot.
