Crimping/ Lug, Contact, Endpiece, Tab...

Electrical connection technique to link a conductor to a device with screw terminals or tabs.

Crimping involves four elements :

• A device with screw terminals or tabs
• A crimp terminal
• A crimping tool, either manual or mechanized (pneumatic or hydraulic)
• A multi-strand wire

The crimp terminal and wire are joined by crimping. The two components are subjected to compression, which will provide a lasting bond between the clamp and the wire.

There are several types of crimp terminals:

Insulated terminals (red, bleu, yellow)

• Open-barrel terminals
• Rolled brazed terminals
• Tubular terminals
• Cable ends, etc.

Crimping verification :

This involves several steps or options:

• Visual compliance verification (checking for a deformed terminal)
• Verification of resistance to tearing (destructive test)
• Dimensional verification (crimp measurements in height and width)
• Compaction verification (microscopic analysis of cross-section of the crimp)
• Automatic inspection on the crimping press (during production)
• Calibration verification (validating the capabilities of the machine/tooling)
