The terminal block is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic. There are holes at both ends for the wire to be inserted. There are screws for fastening or loosening, such as two wires. Sometimes they need to be connected, and sometimes they need to be disconnected. You can connect them with terminals and disconnect them at any time without having to weld them or wind them together, which is very convenient and quick. And it is suitable for a large number of wire interconnections. In the electric power industry, there are special terminal blocks and terminal boxes, all of which are connected terminals, single-layer, double-layer, current, voltage, ordinary, breakable, and so on. A certain crimping area is to ensure reliable contact and to ensure that sufficient current can pass.
