Specifically, it includes a shell 1 and a plurality of installation openings 2 opened on the side wall of the shell 1, and each of the installation openings 2 is installed with a fixing block 3, and the fixing block 3 includes a first installation portion 31 and a second installation portion 32 provided on the first installation portion 31, the first installation portion 31 is fixedly installed on the side wall of the shell 1, and the second installation portion 32 passes through the installation opening 2, and the first installation portion 31 is used to achieve a stop fit at the installation opening 2, so that the entire fixing block 3 is installed and fixed on the side wall of the shell 1. At the same time, a plurality of connecting copper columns 4 with one end extending out of the second mounting portion 32 are provided on the first mounting portion 31, and a first copper bar 5 is connected to one end of the connecting copper column 4 located at the first mounting portion 31, and a second copper bar 6 is connected to one end of the connecting copper column 4 located at the second mounting portion 32. Since the first mounting portion 31 is located inside the shell 1 and the second mounting portion 32 is located outside the shell 1, it is convenient to install electrical components inside and outside the shell 1, wherein a thyristor is installed on the first copper bar 5 and a fuse 7 is installed on the second copper bar 6, thereby moving some electrical components originally integrated inside the shell 1 to the outside of the shell 1, thereby improving the utilization rate of the internal space of the shell 1, such as the area of ​​the first copper bar 5 and the second copper bar 6 can be increased, and after the fuse 7 is installed outside, it can be selected according to the required quantity, which is convenient for expansion.

[0031] At the same time, an input copper busbar assembly 8 is installed on the fuse 7, and the input copper busbar assembly 8 is used to connect the input cable.

[0032] Specifically, a plurality of first mounting holes 33 are provided on the first mounting portion 31, and the connecting copper column 4 passes through the first mounting hole 33. After the connecting copper column 4 passes through the first mounting hole 33, the first copper bar 5 and the second copper bar 6 are respectively fixed at both ends to achieve the fixation of the first copper bar 5 and the second copper bar 6. Specifically, the structural stability of the first copper bar 5 and the second copper bar 6 is maintained during the fixing.
