[0021] Through the above technical solution, the mounting plate 1 is provided with mounting holes for mounting it on a wall or a clamp.

[0022] When using the wire clamp to fix the low-voltage overhead insulated wire, first break the double-core wire, and then place it between the upper and lower connecting grooves 412 and the fixing grooves 421, then press the insulating cover plate 42 and the clamping plate 2 to the mounting plate 1, and then tighten the fixing nut 31 to complete the fixation. During the installation of the wire, all parts are on the mounting plate 1, and there is no separate separation to avoid loss, no need to search during installation, easy installation, and high installation efficiency.

[0023] The insulating base 41 and the insulating cover 42 are directly in contact with the wire to avoid leakage and improve safety. The connecting protrusion 411 protrudes toward one side of the clamping plate 2, increasing the distance between the wire and the mounting plate 1, further avoiding leakage and improving safety.

[0024] Specifically, two of each of the first through hole 11, the second through hole 21, the first fixing hole 413, and the second fixing hole 422 are provided and located between the upper and lower wires, so that a small number of holes are installed and the stability after installation is high.

[0025] Specifically, a gasket is provided between the fixing nut 31 and the clamping plate 2 to prevent the nut from loosening.

[0028] Through the above technical solution, the upper insulating edge 423 and the lower insulating edge 424 allow the wire to be separated from the clamping plate 2 more completely, further avoiding leakage and improving safety.

[0029] Specifically, the insulating cover plate 42 is provided with positioning protrusions at the left and right ends of the side facing the clamping plate 2 , and the positioning protrusions restrict the clamping plate 2 therein, which facilitates assembly and positioning, and prevents the clamping plate 2 from moving, thereby improving the stability of the position of the clamping plate 2 .

[0037] As an improved specific implementation, a second groove 425 is provided at one end of the insulating cover plate 42 facing the clamping plate 2 , and the second groove 425 is spaced apart from the first fixing hole 413 .

[0038] Through the above technical solution, the second groove 425 is provided to reduce the mass of the insulating cover plate 42 without affecting the structural strength, making installation easier, reducing material usage and reducing costs.

[0039] As an improved specific implementation, the mounting plate 1 is provided with vertically arranged reinforcing ribs 12 .

[0040] Through the above technical solution, the reinforcing ribs 12 are vertically arranged to improve the structural strength of the mounting plate 1.

[0041] As an improved specific implementation, a slot 13 is provided on the side of the mounting plate 1 facing away from the insulating base 41 , and the slot 13 is connected to the first through hole 11 to accommodate the fixing bolt 3 .

[0042] Through the above technical solution, the end of part of the fixing bolt 3 is located in the slot 13.
