[0039] Specifically: the connection limit column 401 provides a movable track for the fixed movable cylinder 402 .

[0040] Working principle: In the initial state, the cover plate 111 is in the open state. The worker lifts the pressing plate 302, and the spring 1 303 is deformed by force. One end of the electrical wire to be connected passes through the gap between the pressing plate 302 and the wiring slot 101, and one end of the electrical wire is placed on the surface of the slice 106. The pressing plate 302 is released, and the pressing plate 302 returns to the original position under the action of the elastic force of the spring 1 303, squeezing and fixing the placed electrical wire, and then the cover plate 111 is closed. The cover plate 111 rotates around the cover plate rotation slot 110, and the clamping ring 113 extends. The clamping ring 113 is inserted into the movable groove 109 of the clamping ring and squeezes the fixed movable cylinders 402 on both sides. The two fixed movable cylinders 402 move away from each other, and the spring 2 403 is deformed. When the clamping ring 113 rotates to the bottom of the fixed movable cylinder 402, since the fixed movable cylinder 402 is not squeezed by the clamping ring 113, the fixed movable cylinder 402 returns to its original position under the elastic force of the spring 2 403, and the clamping ring 113 is limited and fixed. At the same time, the pressing block 112 squeezes the installed electrical wires, so that the electrical wires are squeezed by the slice 106 and The conductive metal inside the electrical wire is broken open to connect with the slice 106. Similarly, the electrical wire is installed on the other side. Under the connection of the connecting piece 105, the two electrical wires are electrically connected. This design makes it unnecessary to use screws to fix the multifunctional electrical wiring terminal for electromechanical engineering during the installation of the electrical wire, which improves the installation efficiency. According to the number of electrical wires to be installed, the installed multifunctional electrical wiring terminal for electromechanical engineering is extended into the interior of the second connecting groove 107 through the connecting block 202, so that one end of the special-shaped spring 204 is squeezed by the clamping rod 201 and deformed and opened. After the clamping rod 201 enters the interior of the special-shaped spring 204, the special-shaped spring 204 restores its original shape to limit the clamping rod 201, so that multiple multifunctional electrical wiring terminals for electromechanical engineering are connected to each other. This design allows the electrical wiring terminals to be spliced ​​by themselves as needed, and the flexibility is improved. This electrical wiring terminal does not need to perform pre-treatment of peeling the installed electrical wires, and does not need to use screws to assist in fixing the electrical wires. At the same time, it can be spliced ​​by itself as needed, which increases the versatility of this electrical wiring terminal.
