Abstract
The invention discloses an air-permeable nut for protection of electrical and electronic equipment. The air-permeable nut comprises a shell of the nut, a thread counter bored hole is formed in the shell, and a plurality of air permeating holes are formed in the bottom of the thread counter bored hole. An expanded polytetrafluoroethylene microporous film is arranged between the air permeating holes and the thread counter bored hole. The surface of the expanded polytetrafluoroethylene microporous film is modified through a perfluoro caprylic acid water and oil repellent finishing agent, so that the surface tension of the expanded polytetrafluoroethylene microporous film is 10-15 mN/m. In this way, the air-permeable nut has the function of regulating atmospheric pressure balance of the interior of an equipment shell and the outdoors through convection ventilation, and also has the functions of ventilation, heat dissipation, water resistance, and oil permeation repellency; it can be ensured that electrical performance is brought into play effectively, and the air-permeable nut plays an important role in reducing the fault rate and improving the reliability of the electrical equipment; as for a product protected by the air-permeable nut, the functions of the product can be brought into play normally, and the product is long in service life, safe and reliable; the cost of the industrial product can be lowered, and the competitiveness of the product is improved.
