It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figures 1-4, it is a schematic diagram of an embodiment of a distributor for building indoors according to the present invention, which can be used to realize high-power transmission in building rooms. The distributor 20 in this embodiment includes a PCB board 21 and the PCB board 21 is provided with a power transmission copper bar, an incoming line port 211 and a plurality of wiring ports 213, and the incoming line port 211 and the wiring ports 213 are electrically connected by a power transmission copper bar . The power transmission copper bar includes a live wire copper bar and a neutral line copper bar (in practical applications, it can also include a ground wire copper bar), and the live wire copper bar and the neutral line copper bar are separated by insulating materials or the substrate of the PCB board 21, Therefore, the insulation is realized through the substrate of the PCB board, and both the incoming line port 211 and the connection port 213 are electrically connected to the live line copper bar and the neutral line copper bar.

The inlet port 211 of the above-mentioned distributor 20 is connected to an external input power source through the power line 40 , such as a power distribution box at a place where the strong electricity of the building enters the home.
