Terminal Block consists of fixed terminal block (hereinafter referred to as socket) and free terminal block (hereinafter referred to as plug). The socket is fixed on the electric parts through its square (round) plate (welding method is also adopted for some), the plug is generally connected with the cable, and the plug and socket are connected by connecting nuts.
The terminal block consists of three basic units: shell, insulator and contact body.
Strictly speaking, terminal block refers to a solid device composed of an insulating base and more than one live part. Each conductive member can be used as a joint point for connecting two or more conductors (wires), and also as a tool for connecting or not connecting conductors (wires) individually. In the literal sense, the terminal block can be thought of as a wiring platform providing terminal or wire connection. The terminal block can be a combination type or a single-piece design. The combined terminal block is stacked in the way similar to the block combination, and the two ends are added with side covers and locked and fixed with screws. As for the single terminal block, the combination process mentioned above is not necessary, and it can be used alone.
