Short answer:<\/strong> Crimped stamped terminals should be quoted with wire size, crimp geometry, and pull-force evidence. The RFQ should define conductor range, insulation diameter, crimp height, barrel design, burr direction, plating, applicator condition, pull-force limit, sample size, cross-section evidence, and whether terminals are supplied loose, on strip, or on reels.<\/p>\n

A stamped terminal can be dimensionally acceptable and still fail in harness assembly if the crimp barrel cuts strands, under-compresses the conductor, opens during pull testing, or feeds poorly through the applicator. Pull-force requirements should be discussed before the stamping and carrier design are frozen.<\/p>\n

Crimp inspection details before quoting<\/h2>\n\n\n\n\n\n\n\n\n
Detail<\/th>\nWhy it matters<\/th>\nRFQ information<\/th>\n<\/tr>\n<\/thead>\n
Wire range<\/td>\nOne terminal may not crimp every conductor size reliably.<\/td>\nWire gauge, strand count, insulation OD, and strip length.<\/td>\n<\/tr>\n
Crimp barrel geometry<\/td>\nWing length, radius, serration, and burr side affect strand damage and grip.<\/td>\nConductor wing, insulation wing, bellmouth, and cutoff tab.<\/td>\n<\/tr>\n
Pull-force limit<\/td>\nDifferent standards and customers use different minimum values.<\/td>\nMinimum force, test speed, sample count, and failure mode.<\/td>\n<\/tr>\n
Evidence type<\/td>\nA pull test alone may miss poor compression or strand cutting.<\/td>\nCrimp height, cross section, photos, and report template.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Separate terminal stamping from crimp validation<\/h2>\n

The stamping supplier may make the terminal, but the final crimp result also depends on wire, applicator setup, crimp height, tooling wear, strip feed, and operator control. The RFQ should be clear about whether the supplier is quoting only stamped terminals or also validating crimped samples.<\/p>\n

If crimp validation is included, identify the exact wire and machine condition. A sample crimped with substitute wire can prove the terminal shape, but it may not prove the customer harness. If the product also needs electrical acceptance, connect the requirement to the contact resistance and continuity test guide<\/a>.<\/p>\n

If terminals will be crimped by a different plant, ask for a strip sample that can run through the real applicator before production approval. Also confirm whether plating thickness near the barrel is controlled with the terminal plating thickness inspection guide<\/a>, because buildup can change the crimp window.<\/p>\n

Control burr side, plating, and carrier handling<\/h2>\n

Burr direction matters in the crimp barrel. A burr toward the strands can cut wire during compression. A burr on the carrier cutoff can interfere with feeding. Plating thickness can also change barrel behavior and connector fit, especially on small terminals.<\/p>\n

For terminals supplied on reels, define feed direction, pitch, reel orientation, splice rule, leader length, tail length, and packaging protection. A perfect loose terminal is not enough if the reel stops the applicator. Cleanliness can matter as well, especially when the crimped terminal is later soldered, welded, or tested for low resistance.<\/p>\n
