How's the terminal?

You mean terminals where several wires are shorted together? If there are only a few wires, you can use straight-through terminals. This is a copper tube of 6 square meters, about 10 cm long. It's empty. Peel off the wires and ends that need to be shorted, and press the two groups of wires with wire pressing pliers after they enter. Of course, you can knock with a hammer, but it's not so beautiful. The external insulation can be directly made of heat shrinkable tube or electrical tape. This kind of straight pipe is recommended because it can be hidden in PVC trunking, which is small in size and convenient to use.
