Technical Field
[0001] The utility model relates to a power distribution box. Background Art
[0002] The power distribution box is a device used to supply power, distribute electrical energy, and protect and control circuits. They are the final equipment of the power distribution system, usually installed indoors or outdoors, and are used to manage circuits and protect equipment from electrical faults such as overloads and short circuits. When the internal cables of the power distribution box are connected to the external cables, they are generally transferred through the wiring terminals installed on the wiring holes. The wiring holes are generally standard sizes with several fixed sizes. The diameter of the wiring holes in the power box is generally fixed and cannot be changed before factory assembly. However, the internal components of the power distribution box will be different according to customer needs, so the diameter of the wiring holes will be the same. The original method is to use a customized method for one box of one specification, which cannot be mass-produced. This leads to high production costs, extremely inflexible use, and limited scope of application. Improvements and optimizations are made for this. Utility Model Content
