In the actual use process, in order to play the role of the terminal block, reasonable connection is very important, so how do we operate to ensure the connection effect of the terminal? In today's enterprises, the terminal block to ensure the effect of wire connection plays an irreplaceable important role, and it is also the basic premise for the realization of intelligent equipment in electrical and other industries. Therefore, it is required to be able to master the operation process and skills of wiring terminal, which is the core element to play its wiring stability and accuracy, such as whether the operation force is moderate or not, and whether the selection of tools is matched With, will have a certain degree of impact on its performance, once rough operation, wiring effect is difficult to achieve the ideal state. The operation in line with the process is the strong guarantee for the terminal to play its due effect. In this process, the changes of working conditions and environment will also have different effects. Therefore, the definition of wire type can not be ignored. Only the matching terminals and wires can improve the connection effect. Therefore, when connecting the terminal, the correct method should be used to connect, so as to ensure the function of the terminal in the actual use.
