Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of distribution box especially relates to a high strength impact resistance distribution box. BACKGROUND

[0002] In modern power systems, distribution boxes as key nodes of power transmission and distribution, their performance and reliability directly affect the stability and safety of power supply. With the acceleration of industrialization and the advancement of urbanization, distribution boxes not only need to meet the basic power distribution function, but also need to have the ability to cope with complex environmental conditions. Especially in outdoor or industrial environments, distribution boxes face extreme weather, mechanical impact and chemical corrosion and other multiple challenges.

[0003] At present, most distribution boxes are made of galvanized steel sheet or glass steel. Galvanized steel sheet has good corrosion resistance and certain mechanical strength, and its strength and hardness can be further improved through cold rolling process. Glass steel is widely used in outdoor distribution boxes due to its light weight, high strength and chemical corrosion resistance. In structural design, traditional distribution boxes usually adopt simple box structure, and the internal electrical components are installed and fixed by partition and support. In order to enhance the impact resistance, some designs will add reinforcing ribs outside the box or set up buffer layer inside to absorb and disperse external impact force.

[0004] However, the existing distribution box still has significant deficiencies in strength and impact resistance when facing external impact. Due to the limitation of material and structure, when the distribution box is subjected to a large external impact, such as natural disasters (earthquake, typhoon) or human impact, the box body is easy to deform or crack. Such physical damage not only affects the sealing performance of the distribution box, but also causes damage to the internal electrical components, leading to short circuit, power failure and even fire accidents. For example, in industrial environment, accidental collision of heavy machinery causes serious deformation of distribution box, which affects the stability of power supply.
