Cold-pressed Pin User Guide: How To Ensure The Wire Is Fully Inserted Into The Wiring Hole?
To ensure a wire is fully inserted into a cold pressing needle, strip the insulation to match the terminal barrel length exactly. Insert the conductor into the crimp contact pin until the insulation rests against the wire stop. Operators must visually confirm that the bare conductor is visible through the inspection hole before initiating the final compression.
Steps to Ensure Wires are Placed Securely
Strip and Measure with Care
Achieving a reliable connection requires exact wire stripping. Removing 5 to 7 millimeters of insulation provides the perfect length for a standard crimp contact. Never twist the copper strands after stripping, as this increases the outer diameter and prevents the wire from sliding smoothly to the bottom of the contact socket crimp barrel.
Inspect Before Visual Crimp Execution
Complete insertion guarantees mechanical stability. The bare conductor must fill the entire cavity of the crimp contact female terminal. Utilizing a built-in sight hole allows maintenance teams to verify that the core reaches the deepest point, preventing high resistance or complete terminal failure under heavy vibrational loads in industrial settings.
Standard Stripping and Insertion Reference
| Wire Size (AWG) | Strip Length (mm) | Target Insertion Depth (mm) |
|---|---|---|
| 16 AWG | 6.0 mm | 6.5 mm |
| 18 AWG | 5.5 mm | 6.0 mm |
| 20 AWG | 5.0 mm | 5.5 mm |
Maintaining Connection Integrity
Faulty insertions lead to overheating and intermittent signals. Following strict measurements prevents the insulation from entering the crimping zone, which creates a weak point. Ensuring the entire wire core rests inside the cold pressing needle guarantees a low-resistance path, optimizing the overall lifespan and safety of heavy-duty electrical connector systems.
