Right-angle step fixed high-voltage large-current wiring terminal

Abstract

The embodiment of the invention discloses a right-angle step fixed high-voltage large-current wiring terminal. The right-angle step fixed high-voltage large-current wiring terminal comprises a first wiring terminal and a second wiring terminal, wherein a first end of the first wiring terminal is a hollow cylindrical segment, a second end of the first wiring terminal is of a bending plate structure, the bending plate structure comprises a first bending plate and a second bending plate, installation holes are formed in both of the first bending plate and the second bending plate, a first step structure is arranged at an inner side of the first bending plate, a first end of the second wiring terminal is of a hollow cylindrical segment, a second end of the second wiring terminal is of a squarecolumn structure, a first plane and a second plane are arranged at an outer side of the square column structure and are matched with an inner side of the bending plate structure, installation holes are formed in each plane and penetrates through the square column structure, a second step structure is arranged on the first plane, the two planes of the square column structure of the second wiring terminal are in contact with the inner side of the bending plate structure of the first wiring terminal and are fixed by two groups of bolts. By implementing the embodiment of the invention, displacement between terminals can be prevented, and meanwhile, the contact area of the wiring terminal is expanded.

Description

technical field [0001] The invention relates to a high-voltage and high-current terminal used in a power supply network, in particular to a stepped right-angle fixed high-voltage and high-current terminal. Background technique [0002] The high-voltage and high-current terminal is a metal part used to connect large-scale electric equipment. Its function is to conduct current. One end is a hollow cylindrical section. It is processed into a regular hexagon by hydraulic extrusion during installation. It is used for the same cylindrical shape. High-voltage wires, bushing terminals, etc. are permanently connected; the other end is a flat section with mounting holes, which is connected by bolts for easy installation and disassembly. [0003] The plate sections connected by bolts in the existing high-voltage and high-current terminals are generally single-sided plate-shaped, with limited contact area, and because the contact surface is a pure plate, there is no tight mechanical lim...

AI Technical Summary

Problems solved by technology

[0003] The plate sections connected by bolts in existing high-voltage and high-current terminals are generally single-sided plate-shaped, with limited contact area, and because the contact surface is a pure plate without a tight mechanical limit structure, displacement between plates is easy to occur, and the connecting bolts are loose. Cause poor contact, heat and other problems, resulting in electrical equipment must be powered off for maintenance
