Semi-automatic terminal crimping is a common wire harness processing technique, mainly used for crimping wires to terminals. Here are the techniques and methods for semi-automatic terminal crimping:
Preparation:
Ensure the equipment (semi-automatic terminal crimping machine) and tools (such as crimping dies) are in good working order.
Check that the specifications of the terminals and wires match to avoid poor crimping due to size mismatch.
Clean the workbench to avoid obstruction.
Equipment Debugging:
Adjust the pressure and stroke of the crimping die according to the specifications of the terminals and wires. The pressure range is typically 50-200N; specific values should be referred to the terminal manufacturer's technical parameters.
Test the crimping effect to ensure the terminal and wire are firmly connected without looseness.
Operating Steps:
Insert the wire into the terminal, ensuring consistent insertion depth (usually 2/3 of the terminal length).
Place the assembled terminal and wire into the crimping die and start the machine to crimp.
Inspect the crimped terminal to ensure there are no deformation, cracks, or poor contact.
Precautions:
Avoid excessive force during crimping to prevent damage to terminals or wires.
Regularly check crimping quality and conduct random pull-out tests (typically requiring ≥50N).
For high-frequency applications (such as automotive wiring harnesses), pay special attention to the waterproof performance and contact resistance of the terminals.
