Once you have the PDF, do not simply store it on a hard drive. To gain value:
| Parameter | Requirement (Typical) | |-----------|----------------------| | Wire diameter | 0.1 mm to 1.0 mm (extensions for 1.5 mm by agreement) | | Terminal material | Cu-alloy, steel, or brass, typically tin or silver plated | | Number of turns | Minimum: 1.5 (starts: see standard fig.) | | Winding tension | Defined but depends on wire material and diameter | | Post condition | No burrs, correct hardness (typically HV 80–130) | iec 60352-5 pdf
Wrapped connections can be unwrapped and re-wrapped several times without damaging the terminal post, provided procedures follow the standard’s guidance. Once you have the PDF, do not simply
Unlike soldering, wrapping requires no external heat. This eliminates thermal shock to sensitive components and removes the risk of flux contamination—critical for high-impedance circuits and medical electronics. This eliminates thermal shock to sensitive components and
Abstract IEC 60352-5 defines the requirements for solderless wound connections, specifically where a solid round wire (the winding wire) is tightly wrapped around a terminal post (typically rectangular or square in cross-section). This paper explores the mechanical and electrical theory of connection formation, the critical parameters defined by the standard, the rigorous test sequences (mechanical, climatic, and electrical), common failure modes, and practical design guidelines for high-reliability applications (e.g., transformers, coils, motors, and automotive electronics).
