[0002] As an important part of the power system, the distribution box has the functions of distributing electric energy, controlling power lines and protecting the safe operation of circuits. The distribution box is usually installed in buildings, factories or other facilities to distribute power from the main power supply to various electrical equipment or areas. The distribution box integrates various electrical components such as circuit breakers, switches, fuses, current transformers and voltage transformers. These components work together to ensure the stable operation of the power system.

[0003] The design of traditional distribution boxes is fixed, and the internal layout and installation position of electrical components are determined during manufacturing, which cannot be changed by users. Although the traditional design of distribution boxes ensures reliability and safety to some extent, it also limits flexibility and adaptability.

[0004] Traditional distribution boxes usually have fixed stud structures or slots for mounting component fixing plates. The position and number of studs are fixed and cannot be adjusted flexibly according to the actual needs of electrical components, which leads to unreasonable layout between electrical components, causing space waste or interference between components. Due to the fixed internal layout, traditional distribution boxes have limitations in adapting to different electrical components or different application scenarios. For example, when adding or replacing electrical components, the entire electrical box may need to be replaced or complex disassembly and re-layout may be required, increasing cost and time. The fixed installation of component fixing plates makes maintenance of electrical components relatively difficult. Once a component fails, maintenance personnel may need to disassemble multiple components to find the fault point for repair, which increases the difficulty of repair and wastes a lot of time.
