INDUSTRIAL CRIMP QUALITY HANDBOOK Order No. 64016 0065 American Wire Gauge. It is the standard system for designating wire diameter. Barrel It is the back end portion of a terminal or contact. It is crimped to the conductor, insulation, or both. When designed to receive the conductor, it is called the conductor barrel. When designed to support or grip the insulation, it is called the insulation barrel. Wire Harness Manufacturing: A Wire Harness Assembly Guide A wire harness assembly maximizes efficiency by binding wires together in a safe and secure routing pattern with the use of wire management products has as tie wraps, PVC, slit loom tubing and a wide range of sleeving. The industry standard for Wire Harness Manufacturers is the IPC 620 Certification. QUALITY CRIMPING HANDBOOK shearwater As a general rule, the insulation crimp should withstand the wire being bent 60 to 90 degrees in any direction, several times. Use care when working with small wire sizes so the wire at the back of the insulation crimp does not shear. Crimp Quality Standards parison and Trends The most specific standard for wire harness makers is the IPC WHMA A 620 standard, covering everything from crimping and soldering to lacing and tie wrapping.
