Terminal blocks are designed to facilitate the connection of wires. They are essentially metal strips enclosed in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For instance, when two wires need to be connected or disconnected, terminal blocks can be used to join them, allowing for easy and quick disconnection without the need for welding or wrapping them together. This is particularly convenient and efficient.Moreover, terminal blocks are suitable for the interconnection of a large number of wires. In the electrical industry, there are specialized terminal block strips and terminal block boxes, which are filled with various types of terminal blocks, such as single-layer, double-layer, current-carrying, voltage-carrying, standard, and disconnectable ones. A certain crimping area is necessary to ensure reliable contact and to guarantee that sufficient current can pass through.
