Description

Technical Field

[0001] The utility model relates to the technical field of industrial connectors, more specifically to a junction box. Background Art

[0002] A junction box is a type of industrial connector. It converts a single incoming power or data line into multiple output currents or data signals through shunting. However, when using a junction box to connect electrical appliances, it often requires a matching power line to connect the box to the appliance. Furthermore, installation requires careful consideration of the location and distance between the box and the appliance. This can make the junction box inherently less adaptable and increase installation workload.

[0003] Therefore, in response to the current problems, how to provide a junction box that can ensure that the junction box itself can store a sufficient length of power transmission lines to enhance the adaptability of the junction box, and also ensure that the installation and use of the junction box can be easier, is an issue that technical personnel in this field urgently need to solve.
