When Operating The Cold-pressed Needle Crimper, The Insulation Layer And The End Insulation Sleeve Must Be Tightly Fitted.

When using the contact crimper connector, the conductor insulation and the pre-installed insulating sleeve at the end must be in perfect contact. This ensures the sleeve completely covers the end of the conductor insulation, maintaining a seamless connection between the conductor and the sleeve's interior. An imperfect fit will result in gaps between the metal conductor and the outer insulating sleeve, potentially causing poor contact or reduced insulation performance.

The fit between the d sub contact crimper sleeve and the conductor insulation plays a crucial role in the final crimping quality. Only when the internal dimensions of the insulating sleeve match the outer diameter of the conductor insulation can a tight outer sheath be guaranteed after crimping.

During the crimping process, the pre-installed insulating sleeve first slides into the conductor, and then the contact crimping tool sleeve compresses and shapes the end and conductor. During this process, a stable structure is formed between the metal conductor bundle and the insulating sleeve. After crimping, inspect the connection between the sleeve and the insulation layer. If there is no room for slippage and no exposed metal conductor bundle, the fit is good. If the sleeve is loose or the insulation layer is exposed, the crimping should be repeated.
