无焊连接.第7部分:弹簧夹连接.一般要求 试验方法和实用指南

[中文适用范围]： 本部分IEC 60352适用于使用剥离导线而无进一步准备的弹簧夹连接： 实心导体标称直径0.32 mm至3.7 mm（截面积0.08 mm²至10 mm²），或绞合导体截面积0.08 mm²至10 mm²，或柔性导体截面积0.08 mm²至10 mm²， 根据IEC 60228或IEC 60189-3，用于电气和电子设备及组件。 除测试程序外，还包括材料和工业经验数据，以提供在规定环境条件下电气稳定的连接。 本文件的目的是确定弹簧夹连接在规定的机械、电气和大气条件下的适用性。 注：IEC指南109提倡在整个产品生命周期中最小化产品对自然环境的影响。可以理解的是，本文件中允许的某些材料可能对环境产生负面影响。随着技术进步，这些材料将被可接受的替代品取代，并从本文件中删除。 [外文原描述]： IEC 60352-7:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60352-7:2020 is applicable to spring clamp connections made with stripped wire without further preparation: - solid conductors of 0,32 mm to 3,7 mm nominal diameter (0,08 mm2 to 10 mm2 cross‑section), or - stranded conductors of 0,08 mm2 to 10 mm2 cross-section, or - flexible conductors of 0,08 mm2 to 10 mm2 cross-section, according to IEC 60228 or IEC 60189-3 for use in electrical and electronic equipment and components. Information on materials and data from industrial experience is included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this document is to determine the suitability of spring clamp connections under specified mechanical, electrical and atmospheric conditions. This second edition cancels and replaces the first edition of IEC 60352-7, published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) correction of the two flow charts in Figure 6 and Figure 7, b) split the content into more clauses for better separation between full test schedule and basic test schedule, c) relocating the content of former Clause 6 Practical guidance into an informative Annex A, as now common in the IEC 60352 series for solderless connections, d) clarification on conductor types with reference to classes defined in IEC 60228.
