Description

Technical Field

[0001] The utility model relates to the technical field of electrical junction boxes, and particularly relates to a assembled electrical junction box. Background Art

[0002] A power distribution cabinet is a device used for power distribution, control, and protection. It is usually used to introduce power into different electrical devices or loads, and through internal components such as circuit breakers, fuses, contactors, etc., to achieve the distribution, control, and protection of current. An electrical junction box is usually assembled on the power distribution cabinet. The junction box can provide a safety isolation function for electrical circuits. It concentrates the connection points between the incoming line and the outgoing line inside a box, effectively isolating the electrical connection between the high-voltage power supply and the low-voltage equipment. Therefore, once maintenance is required, only the power supply at the junction box needs to be cut off, without the need to operate on the entire power distribution cabinet, improving the safety of operation.

[0003] Existing electrical junction boxes usually consist of a protective box body and internal connection components, which are used to electrically connect different circuits or devices together. However, most of their box bodies are of an integral structure and cannot be easily expanded or additional connection points added. If more power lines or connection lines need to be added, the entire box body may need to be replaced, increasing the cost and workload. Summary of the Invention
