[0002] A junction box is a device used to connect and protect wires in an electrical system. The main functions of a junction box include connecting wires and protecting them. A junction box provides a safe and secure location for connecting wires in an electrical system. These wires may come from different circuits or devices. The junction box provides a centralized place to make connections. The connection points and terminals inside the junction box are usually designed to secure the wires to prevent them from loosening or accidentally falling off. This ensures the stability and safety of the circuit connection.

[0022] In particular, the locking assembly 4 includes a fixed shell 41 and a positioning rod 42. The fixed shell 41 is fixedly connected to the interior of the junction box body 1. The outer wall of the positioning rod 42 is slidably inserted and sleeved with the fixed shell 41. The positioning rod 42 is used to limit the mounting column 3. The end of the fixed shell 41 is fixedly connected to the fixed column 2. The fixed shell 41 and the fixed column 2 are provided with connecting holes on the opposite sides. The outer wall of the positioning rod 42 is slidably sleeved with the connecting hole. The mounting column 3 is provided with a plurality of positioning grooves 43 equidistantly on the side of the fixed shell 41. Therefore, the positioning rod 42 is engaged with the positioning grooves 43 at different positions on one side of the mounting column 3, so that the mounting column 3 can be at different depths inside the fixed column 2.
