[0025] The mounting assembly 20 includes two groups of cylinders 21 arranged on the base plate 10, and the cylinders 21 are movably provided with lining rods 22. The front end of the lining rods 22 is provided with pillars 23, and the pillars 23 are connected to insulating cross plates 24. The insulating cross plates 24 extend along the length direction of the distribution cabinet. A plurality of busbars 30 are installed on the insulating cross plates 24 at intervals by bolts. A wire 111 is provided on the switch 11, and the wire 111 is connected to the busbar 30.

[0026] That is, the plurality of busbars 30 are isolated from each other and do not contact each other on the insulating horizontal plate 24, so that a short circuit will not occur.

[0027] The support 23 is rotatably connected to a cover 25 . The cylinder 21 has a threaded section. The cover 25 can be screwed onto the threaded section to drive the liner rod 22 to retract into the cylinder 21 . A spring 26 is provided in the cylinder 21 , and the spring 26 abuts against the rear end of the liner rod 22 .

[0028] When installing the busbar 30, the insulating cross plate 24 can be taken out of the distribution cabinet to install several busbars 30, avoiding the limitation of the space of the distribution cabinet and facilitating the installation. After the installation is completed, the lining rod 22 is inserted into the cylinder 21 and the insulating cross plate 24 is pushed close to the base plate 10, and then the cover body 25 is tightened on the threaded section to drive the lining rod 22 to retract into the cylinder 21, so as to fix the position of the insulating cross plate 24 for installing the busbar 30 in the distribution cabinet.

[0029] When maintaining the distribution cabinet, the cover 25 can be unscrewed from the threaded section, and the insulating cross plate 24 can be extended out of the cylinder 21 through the lining rod 22 and moved outward, so that several busbars 30 on the insulating cross plate 24 can be wiped to remove dust or dirt, without the need to disassemble the busbars 30, thereby improving maintenance efficiency.
