In case of poor contact during the use of the terminal, you must find out the cause of poor contact of the terminal and handle it in time to avoid greater loss due to delay. Then, what causes the poor contact of the terminal block?
Cause analysis of poor contact of wiring terminal
The wiring terminal is composed of metal conductor and insulating material, which transmits external voltage, current or signal to the corresponding contact of the corresponding connector. Therefore, the reasons for poor contact of the terminal may include: unreasonable terminal structure design, unqualified metal conductor, size error, improper assembly, improper operation and use, etc. Environmental protection trunking
resolvent
Therefore, before use, the following methods can be used to prevent the occurrence of poor contact during the use of the terminal:
1. Before use, conduct point by point conduction test on the terminal block to see if it meets the requirements.
2. Correctly install the terminal in strict accordance with the terminal operating instructions;
3. Test the plug-in force or retention force of the terminal to prevent poor contact caused by relaxation of individual jacks.
