Abstract: in case of poor contact during the use of wiring terminals, you must find out the causes of poor contact of wiring terminals in time and deal with them in time, so as to avoid greater losses caused by delay. Then, what causes the poor contact of the wiring terminal? Let's follow the editor of Ningbo Hongyi electric.
Cause analysis of poor contact of wiring terminals
The wiring terminal is composed of metal conductor and insulating material, which transmits external voltage, current or signal to the contact corresponding to its matching connector. Therefore, the reasons for poor contact of wiring terminals may include: unreasonable terminal structure design, unqualified metal conductor, size error, improper assembly, improper operation and use, etc.

Therefore, before use, the following methods can be used to prevent the occurrence of poor contact of wiring terminals in use:
1. Before use, conduct point by point conduction test on the wiring terminal to see whether it meets the requirements.
2. Correctly install the terminal in strict accordance with the operating instructions;
3. Test the plug-in force or retention force of the wiring terminal to prevent poor contact caused by individual Jack relaxation.
