[0001] This utility model relates to the field of busbar trunking junction box technology, and in particular to a busbar trunking junction box. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute a large amount of power to various components of a distributed system. In indoor low-voltage power transmission trunk line projects, it has increasingly replaced wires and cables. With the rapid development of urban modernization in my country and the continuous improvement of people's living standards, the country's requirements for electricity use and personal safety are also getting higher and higher. Busbar trunking is widely used in power transmission trunk lines. Plug-in boxes need to be installed on the busbar trunking to distribute power.

[0003] The existing connection method between the busbar junction box and the copper busbar inside the busbar is achieved by inserting the pins through the junction box into the busbar and clamping them into contact with the copper busbar inside the busbar. However, traditional busbar junction boxes are prone to damage to the copper busbar during connection due to misalignment of the pins.

[0004] Therefore, it is urgent to research and develop a busbar trunking junction box to solve the above-mentioned technical problems. Summary of the Invention
