Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of connecting hardware, in particular, to a multifunctional connecting hardware. BACKGROUND

[0002] As indispensable metal accessories of power transmission lines, connecting hardware covers materials such as iron and aluminum, and plays a key supporting role in the power transmission system. They are widely distributed throughout the line, and most of them need to face huge tension during operation. For example, the connecting hardware of insulator strings needs to stably bear the weight of the conductor and the additional force of wind and snow to ensure that the line does not sag and break. At the same time, some hardware also shoulders the electrical mission and must ensure good contact to maintain stable current transmission. For example, strain clamps may cause heating and power failure if the contact is poor. Currently, workers operate connecting hardware in high-altitude operations, which requires overcoming high-altitude fear and bad weather, and using skilled techniques and professional equipment to install and maintain accurately at a height of hundreds of meters to protect the lights of millions of families.

[0003] The existing multifunctional connecting hardware has obvious defects and lacks forward-looking consideration in the process of fixing metal conductors. When they fix the conductors, there is no elastic space reserved at all. The metal conductors are exposed to the outdoor environment for a long time and are subjected to harsh weather such as severe cold, heat, wind, rain, lightning, etc. When the temperature fluctuates greatly, the conductor will produce obvious deformation based on the principle of thermal expansion and cold contraction. Since there is no buffer space between the connecting hardware and the conductor, the two are squeezed and pulled by each other, and the serious friction causes the protective layer on the surface of the conductor to be damaged, and the connecting hardware also appears to be worn and deformed, greatly shortening the service life, increasing the line maintenance cost and risk. Therefore, it needs to be improved and optimized. CONTENT OF THE INVENTION
