Precautions For Pressing The End Of The Cold-pressed Needle Crimper

When using crimping contact crimper, the crimping action must ensure the terminal and pin are completely flush, until the terminal shape is fully formed. This guarantees a stable connection between the pin and the wire through cold pressing.

During crimping d sub contact crimper, a terminal and crimping tool mold with the same cross-section as the wire should be selected. After stripping the wire insulation, insert the conductor into the terminal and then crimp with dedicated crimping pliers. When the handle of the crimping tool is pressed all the way down, the terminal metal will undergo plastic deformation, tightly wrapping the wire wire inside the terminal.

After crimping contact crimping tool, visually inspect or pull to check if the terminal deformation is uniform, without cracks, and without exposed copper wires. Observe the end of the terminal to confirm that it is fully formed and that the wire is not loose. If the terminal is irregular or the wire is loose, strip the insulation again, insert again, and crimp again.

After the wire harness is assembled, avoid immediately applying external force or twisting the wire. It is recommended to keep the plug axis aligned with the socket axis and support the cable to prevent uneven stress on the crimped area.
