Component Specifications

Definition
A terminal locator/nest is a precision-engineered component within a crimping head assembly that accurately positions electrical terminals or connectors during automated crimping processes. It ensures proper alignment between the terminal and wire conductor for consistent, reliable electrical connections in mass production environments.
Working Principle
The terminal locator/nest uses precisely machined cavities or guides to hold terminals in exact positions relative to the crimping dies. During operation, terminals are fed into the nest, which aligns them for the crimping cycle. The nest may incorporate spring-loaded mechanisms, sensors, or adjustable features to accommodate different terminal sizes and maintain positioning accuracy throughout high-volume production runs.
Materials
Typically made from hardened tool steel (A2, D2, or M2 grades) or tungsten carbide for wear resistance. May include secondary components of stainless steel, aluminum alloys, or engineered plastics for specific applications.
Technical Parameters
  • Weight 50-200 g (varies by design)
  • Cavity Tolerance ±0.01 mm
  • Surface Hardness 58-62 HRC
  • Maximum Terminal Size 6.0 mm
  • Minimum Terminal Size 0.5 mm
  • Operating Temperature Range -20°C to 120°C
Standards
ISO 9001, DIN 46267, IEC 60352
