Mounting structure of concentrator PCB (printed circuit board)

The utility model provides an installation structure of a concentrator PCB, belongs to the technical field of concentrator PCBs, and aims to solve the problem that an existing PCB installation structure cannot adjust a gap between a PCB and a shell to improve the heat dissipation effect. Stand columns are fixedly connected to the front side and the rear side of the top of the connecting shell and the front side and the rear side of the top of the shell, connecting rods are fixedly installed in the middle of the top of the shell and the middle of the top of the connecting shell, a fixing rod is fixedly attached to the interior of the shell, the outer side of the fixing rod is sleeved with a first spring, and a PCB is installed in the middle of the fixing rod; a top block is fixedly arranged on the surface of the PCB, and connecting ropes are fixedly connected to the left side and the right side of the PCB. According to the invention, the connecting rope is bolted to the surface of the connecting rod, so that t
