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

Abstract

The embodiment of the invention discloses a single-nut grooved conical-surface fixed-type high-voltage large-current wiring terminal, and the wiring terminal comprises a first wiring terminal and a second wiring terminal. The first end of the first wiring terminal is a hollow cylindrical segment, and the second end of the first wiring terminal is a cylindrical segment perpendicular to the axial direction of the first end, wherein a conical hole segment and an installation hole segment which are communicated with each other are formed in the cylindrical segment. The first end of the second wiring terminal is a hollow cylindrical segment, and the second end of the second wiring terminal is a conical shaft segment and a stud segment which extend from the first end. The conical shaft segment is provided with a grooved structure, and the stud segment is provided with an external thread. The second end of the second wiring terminal is accommodated in the second end of the first wiring terminal, and the conical shaft segment of the second wiring terminal cooperates with the conical hole segment of the first wiring terminal. The stud segment of the second wiring terminal passes through theinstallation hole segment of the first wiring terminal, and is fixed through a nut. According to the embodiment of the invention, the wiring terminal can avoid the displacement between terminals, andincreases the contact area of the wiring terminals.

Description

technical field [0001] The invention relates to a high-voltage and high-current terminal used for a power supply network, in particular to a fixed high-voltage and high-current terminal with a single nut and a grooved conical surface. 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, the...
