Crimp height is too large or too small

Motorcycle wire harness wholesalers introduces the crimp height is the cross-sectional height of the crimping zone after crimping, which is the most important feature of good crimping. Excessive crimp height cannot effectively compress the wire core, which will cause excessive voids in the crimping zone. Contact with the metal between the wire and the terminal metal will cause contact resistance to increase, resulting in heat loss. Terminal. Too small a crimp height reduces the cable pull-out force and rated current, which may break the wire core or break the terminal crimping area to break the wire connection, causing the line to open. Check the quality after crimping with a special measuring tool such as a micrometer, and check the crimping pliers and crimping equipment frequently to ensure the quality of the terminal crimping.

Insulation crimping area is too small or too large

Due to the variety of wire types and terminal types, there is no uniform regulation, and only experience is accumulated in actual operation. Insulation crimping provides stress relief for the conductor crimping zone, so that when the cable is worn, the wire crimping zone is not broken due to the buffering of the insulating crimping zone. Therefore, a good insulating laminate is used to protect the wire. Connection has an important role. If the insulation is too small, the metal stress in the insulation crimping zone will be too large, which will weaken its stress-releasing function, while the excessive insulation laminate can not effectively buffer the stress release of the crimping zone of the wire through visual observation. The hand gently shakes the wire, and the insulation crimping area is not shaken. If you want to learn more about best quality double needle bar raschel knitting machine,you can contact us.
