[0002] With the rapid development of my country's economy, energy consumption is constantly increasing, and industrial production and various complex application scenarios are expanding, placing increasingly higher demands on the power system. Traditional low-voltage distribution boxes have certain limitations, such as limited functionality, excessive size, and inconvenient installation and maintenance. Existing technologies mostly use metal enclosures, which are too large and heavy for easy transportation and installation, presenting certain drawbacks and making them unsuitable for special scenarios. They also increase the use of enclosure materials. To address these issues, a non-metallic low-voltage distribution box that fully utilizes the internal space and has a lower manufacturing cost has been developed. Utility Model Content

The end of the terminal block is connected to a busbar assembly for providing sufficient wiring layout space for high current transmission. The busbar assembly is internally connected to cables for transmitting current. The distribution box is internally equipped with a current transformer for connecting cables.

[0005] Preferably, the vertical inner wall of the distribution box is equipped with multiple quick-plug terminal blocks for rapid cable installation, and the sliding mounting plate is made of insulating material.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This high-current miniaturized distribution box structure benefits from the structure of the distribution box body. The box body uses non-metallic materials PC+ABS to replace the traditional metal box, which effectively reduces electromagnetic interference and improves metering accuracy and stability. The unique structural design realizes centralized metering, saves installation space, reduces engineering costs, simplifies electrical design, adopts low power consumption design, reduces the energy consumption of the equipment itself, and meets the requirements of energy conservation and emission reduction.

[0012] This high-current miniaturized distribution box structure benefits from the sliding mounting plate design. Components and accessories are first fixed to the sliding mounting plate, and then the entire sliding mounting plate is placed into the pre-reserved position in the housing for inlay. This new installation method greatly improves efficiency, allowing products to be divided into multiple parts for separate assembly across regions and time periods, reducing the number of repetitive handling operations during production and making production arrangements more flexible. At the same time, maintenance is convenient; when components need to be replaced, there is no need to disassemble the entire metering box extensively, only the corresponding mounting plate needs to be removed and replaced.

The end of the terminal block 2 is connected to a busbar assembly 201 for providing sufficient wiring layout space for high current transmission. The busbar assembly 201 is internally connected to cables for transmitting current. The distribution box 1 is internally equipped with a current transformer 202 for connecting cables.

[0019] The vertical inner wall of the distribution box 1 is equipped with multiple quick-plug terminal blocks 203 for rapid cable installation. The sliding mounting plate 106 is made of insulating material. Components and accessories are first fixed on the sliding mounting plate 106, and then the entire sliding mounting plate 106 is placed into the pre-reserved position in the housing for inlay. This new installation method can greatly improve efficiency, allowing products to be divided into multiple parts and assembled across regions and times, reducing the number of repeated handling during production and making production arrangements more flexible. At the same time, maintenance is convenient. When it is necessary to replace components, it is not necessary to disassemble the entire metering box; only the corresponding mounting plate needs to be removed for replacement.

[0020] The distribution box 1 has a rotating door 102 on its side for observing the electrical components inside. The door 102 is a transparent PC cover, and sensor holes 105 are provided on its surface for mounting sensors. Various sensors, such as smoke sensors and humidity sensors, are installed in the distribution box 1 to monitor the internal environment in real time.
