标准摘要
[中文适用范围]: “IEC 60947 的这一部分规定了主要用于工业或类似用途的 PCB 接线端子的要求。通过焊接@压入或等效方法在印刷电路板上安装和固定,以在铜导体和铜导体之间提供电气和机械连接。印刷电路板。本标准适用于用于连接铜导体@有或没有特殊准备@的PCB接线端子,其横截面在0@05 mm2和300 mm2 (AWG 30/600 kcmil)之间@用于电路额定电压不超过 1 000 V ac 至 1 000 Hz 或 1 500 V dc 注 1:大横截面接线端子专用于大电流 PCB 的特定设计。范围最大为 300 mm,以覆盖任何可能的情况。高电流 PCB 和 PCB 接线端子的示例见附件 C。 注 2 AWG 是“American Wire Gage”的缩写(Gage (US) = Gauge (UK));kcmil = 1 000 cmil;1 cmil = 1 圆密耳 = 直径为 1 密耳的圆的表面; 1 密耳 = 1/1 000 英寸。该标准可用作特殊类型 PCB 端子块的指南,该端子块带有诸如断开单元、集成盒式熔断体等组件。如果本标准适用,则使用术语“夹紧单元”而不是“端子”。在引用 IEC 60947-1 时要考虑这一点。” [外文原描述]: IEC 60947-7-4:2013 specifies requirements for PCB terminal blocks primarily intended for industrial or similar use. Mounting and fixing on the printed circuit board is made by soldering, press-in or equivalent methods to provide electrical and mechanical connection between copper conductors and the printed circuit board. This standard applies to PCB terminal blocks intended to connect copper conductors, with or without special preparation, having a cross-section between 0,05 mm2 and 300 mm2 (AWG 30/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c.
