What causes wire harness terminals to fall off? How to avoid wire harness terminals falling off?

There can be a variety of reasons why a harness terminal may fall off, including the following common factors: Improper Installation: It is very important that the harness terminals are installed correctly. If they are not securely connected or properly crimped, the terminals can easily come loose or fall off. Vibration and Shock: Vibration and shock can occur during vehicle travel or equipment operation, which can cause wiring harness terminals to gradually loosen and eventually fall off. Pulling and tensile forces: The harness may be subject to external pulling and tensile forces, such as overstretching the harness during installation, improper handling, or pulling forces during use, which may cause the terminals to fall off. Harness aging: Over time, the materials and connecting components of the harness may be subject to natural aging, resulting in terminal failure and stripping. The following precautions can be taken to avoid dislodging harness terminals: Proper Installation: Ensure that harness terminals are properly installed and crimped, following the correct operating methods and standards. Use appropriate connection methods: Choose appropriate connection methods, such as soldering, crimping or plugging, etc., and select better connection methods according to specific situations. Regular inspection and maintenance: Regularly inspect the condition of the wiring harness and terminals, including checking for looseness, damage, or wear and tear, etc., and carry out maintenance and repair in a timely manner. Use of fixing devices: For wiring harnesses that are susceptible to vibration and shock, use fixing devices (e.g., ties, clips, etc.) to secure the wiring harnesses and prevent them from loosening or falling off. Use vibration- and shock-resistant wire harness materials: Choose wire harness materials with good vibration- and shock-resistant properties to increase the stability and reliability of the connection. Take care to protect the wiring harness: Avoid excessive pulling, twisting or being subjected to external tension to protect the harness from the risk of damage and disconnection. Proper installation, regular inspection and maintenance, selection of appropriate connection methods and protection of the harness from external forces can reduce the risk of disconnecting the harness terminals and increase the reliability and stability of the harness.
