Practical Methods To Reduce The Jamming Phenomenon Of Cold-pressed Needle Crimping Devices

In daily assembly, the contact crimper device occasionally gets stuck, which not only affects assembly efficiency but may also disrupt the operation rhythm. Understanding the basic principles of metal deformation and tool engagement during crimping operations allows for reasonable analysis and adjustment of common jamming phenomena.

Understanding the Causes of Grinding

d sub contact crimper During crimping, plastic deformation occurs between the metal conductor and the crimping cylinder, forming a strong mechanical and electrical connection. This process requires good contact and deformation between the wire and terminal within the crimping cylinder; otherwise, uneven force transmission may occur during the tool's closing phase, leading to poor crimping engagement.

Operational Improvement

• Key Points for Wire Preparation

The stripping length and conductor arrangement significantly affect the crimping action. Excessively long wire stripping or loose stranding can cause instability in the crimping pin and terminal position, increasing the risk of jamming.

• Crimping Step Breakdown

  • Correctly place the wire into the designated slot of the cold crimping pin crimper and observe whether the wire core is fully inserted into the terminal barrel.

  • Manually adjust the crimping pliers to the pre-crimping stage to secure the wire within the terminal.

  • During the final crimping stage, maintain smooth handle movement, avoiding sudden force or deviation.

These step-by-step instructions help operators reduce jamming caused by uneven posture or force.

Daily Maintenance Recommendations

Regularly check the grooves and moving parts of the cold-press crimper for wear. Groove deformation or insufficient tool lubrication increases friction, thus increasing the probability of jamming. Properly cleaning dust from inside the tool and maintaining smooth mechanical operation also helps improve the overall assembly experience.

Through the above practical adjustments and tool maintenance, the contact crimping can operate more smoothly in field assembly.
