Description

Universal Grounding Clamp

Technical field:

The utility model relates to a safety tool widely used in the electric power industry, in particular to a universal grounding clamp suitable for outdoor busbars or busbars.

Background technique:

At present, the portable grounding clamps used in my country's power system are classified according to the connector form: single tongue type, double tongue type, screw tight type, hand-held flat mouth type, monkey head type and other types. Among them, the single tongue type and double tongue type are mainly used for safety measures when the line or bus is powered off; the screw tight type and the hand-held flat mouth type are mainly used for safety measures when the busbar is powered off. The reason why there are many forms of ground wire clamps is mainly to meet the needs of different shapes of equipment when taking safety measures when power is off.

Due to the different forms of grounding wire clamps, in practical applications, the grounding wire clamps for hanging lines and busbars cannot be conveniently applied to busbar grounding. Similarly, the grounding wire clamps used for busbar grounding cannot be conveniently applied to lines and Grounding of the busbar. This causes the strange phenomenon that some ground wire clamps are insufficient and some ground wire clamps are leftover in actual production. For example, the grounding clamps for hanging the grounding busbar are not enough, and the grounding clamps for hanging the busbar are not available, and vice versa. If a sufficient number of various forms of grounding clamps are provided, capital investment will be required, resulting in increased costs and increased maintenance, and also caused a lot of idle and waste of resources.

Utility model content:

The technical problem to be solved by the utility model is to provide a universal grounding clamp with simple structure, convenient operation, safety and reliability, which can not only meet the requirements for hanging busbars, but also meet the requirements for hanging busbars and wires, thereby reducing the inventory The type and quantity of grounding clips avoid idleness and waste of resources.

The technical scheme that the utility model takes for solving the technical problem is:

A universal grounding clamp, including a hollow insulated operating rod and a grounding clamp joint, the grounding clamp joint includes a left splint and a right splint, the left splint and the right splint are connected together by a strong torsion spring, in the The central position inside the left splint is provided with a busbar or a busbar clamping left groove, and the central position inside the right splint is provided with a busbar or a busbar clamping a right groove, the left groove and the right groove The groove openings correspond to each other; the hollow insulating operating rod and the left splint are of an integrated structure, and the right splint is connected to the pressing handle through a strong torsion spring and a high-strength pull wire inside the hollow insulating operating rod. There is a strip-shaped opening on the cylinder wall at the middle and lower end of the rod, and the pressing handle moves up and down through the strip-shaped opening to drive the right splint to open or close through the high-strength pull wire; the tops of the left and right splints are arc-shaped shape.

A connecting fastening bolt is arranged at the lower right corner outside the right splint, and the ground wire is connected with the right splint through the connecting fastening bolt.

The pressing handle is processed from insulating material.

When in use, press the pressing handle of the utility model, the high-strength pull wire is tensioned, the strong torsion spring is stressed, the right splint is opened, and the busbar or busbar is clamped at the notch of the left splint and the right splint; loosen the splint The utility model presses the handle, the left splint and the right splint are closed, and the slots of the left groove and the right groove are also closed, so that the busbar or busbar is firmly clamped.

In the utility model, since the inner tops of the left splint and the right splint are distributed in an arc shape, the busbar or busbar enters the groove opening more smoothly, and the phenomenon of hanging the busbar or busbar is avoided.

The utility model has the advantages of simple structure, safety and reliability, and convenient use, which solves the problem that the grounding wire clips of the bus bar or the bus bar cannot be used universally in the prior art, and has good practical value and market promotion prospect.
