In the process of Wire Harness production, crimping terminals is a very common step. In the process of using the terminals, when there is a phenomenon of poor contact, it is necessary to find out the reasons for the poor contact of the terminals and deal with them in time, so as not to cause more delays. What is the reason for the poor contact of the terminals? The professional Wiring Harness manufacturer of Kaibaile will take you to understand the reasons and solutions. The composition of the terminal is composed of metal conductors and insulating materials, which transmits the external voltage, current or signal to the corresponding contacts of the corresponding connector. Therefore, the reasons for the poor contact of the terminal may be: terminal structure design Unreasonable, unqualified metal conductors, dimensional errors, improper assembly, and poor contact caused by improper operation and use. Solution: Before use, the following methods can be used to prevent the occurrence of poor contact in the use of terminal blocks: 1. Before use, conduct a point-by-point continuity test on the terminal to see if it meets the requirements. 2. Strictly follow the terminal operation instructions to install it correctly; 3. Test the insertion force of the terminal, check the holding force of the terminal and the core wire, and prevent the looseness of the individual jack and the insufficient tension between the core wire and the terminal, resulting in poor contact.
