4-1579001-1 is a crimp tooling component used in wire termination and barrel crimping applications within electrical connector assembly. The tooling is designed to achieve precise crimp height (CH) and crimp width (CW) control to maintain an Area Index (AI) of approximately 80%, which is critical for ensuring proper electrical and mechanical connection quality. Key dimensional parameters include a nominal crimp height of 0.073 inches and crimp width of 0.110 inches, with a crimper leg taper of 3.0 degrees and anvil width of 0.109 inches. The tooling requires strict dimensional control to minimize clearance variations and prevent defects such as excessive flash, with a nominal anvil-to-crimper clearance of 0.005 inches. This component is essential for maintaining consistent crimp quality, pull test values, and production throughput in high-volume wire termination processes.
