[0034] Further description of the present invention:

[0035] 1) The present invention has three copper bars, which are directly placed in the limiting opening 3010 of the first guide member 301 and fixed by the top cover 302.

[0036] 2) The plug-in guide assembly kit includes a plug-in component 7 and a copper busbar limit assembly that can be freely assembled into an energized plug-in component.

[0037] 3) The conductive sheet 702 of the plug-in component 7 can be connected to a wire, and then the wire is led out from the holes on both sides of the second bottom cover 700 of the plug-in component 7 .

[0038] 4) The power socket 6 of the extension module 5 is a trip-proof power socket.

[0039] 5) After the extension module 5 is inserted into the bottom box 1, the conductive sheet 702 on the extension module 5 clamps the copper bus 4 on the bottom box 1 and is located in the middle area of ​​the copper bus 4, with good contact.

[0040] 6) The main input module 2, expansion module 5 and blank panel 11 are equipped with captive screws to prevent the screws from falling off during installation. After the main input module 2, expansion module 4 and blank panel 11 are in place, fix the captive screws to the bottom box 1.

[0041] 7) The main input module 2 is distributed on the top of the power distribution unit, including the main input air switch and the ground terminal; the expansion module 5 is distributed in the remaining area of ​​the power distribution unit. When the expansion module 5 is not fully equipped, the vacant space is sealed with an empty panel 11. The insulation performance of the present invention meets the relevant electrical requirements.

[0042] 8) The present invention is in a vertical state during installation. The two ends of the present invention use assembled cabinet fixings 14, and different styles are used according to different cabinets.

[0045] 11) The present invention adopts a modular design. The expansion module 5 can be increased or decreased as needed. The absence of any module does not affect the connectivity of the circuits of other expansion modules 5. The circuit phase of the plug-in component 7 on the expansion module 5 is consistent with the circuit phase of the three copper bars 4 on the bottom box 1. The power socket 6 has an anti-tripping device to prevent the plug from loosening and disengaging.

[0046] The installation process of the present invention is as follows: 1. A first guide piece 301 is installed at each installation location of the expansion module 5 to ensure that the copper busbar 4 is upright and convenient for the installation of the expansion module 5. After the three copper busbars 4 are located on the first guide piece 301, they are fixed to the main input circuit breaker (or terminal) to connect the circuit. After the copper busbar 4 is in place, each first guide piece 301 needs to be installed with a top cover 302. The top cover 302 and the first guide piece 301 are locked by snaps on both sides to fix the copper busbar; after the bottom box 1 and the expansion module 5 are assembled and their internal circuits are connected, the main input module 2 and the expansion module 5 are installed into the bottom box 1 along the guide rail. When installing the expansion module 5, it is necessary to press down hard to insert the module into place, and the plug-in piece 7 clamps the copper busbar; in the area on the bottom box 1 where no expansion module 5 is installed, an empty panel 11 is installed.
