标准摘要
[中文适用范围]: IEC 60512 的这一部分定义了一种标准测试方法,用于测量连接器或配有附件并以电缆端接的连接器的屏蔽效能。整个组件在其整个长度上具有连续的 360° 屏蔽能力。该测试方法利用的原理是,连接器/附件/电缆组件的固有屏蔽特性是其表面传输阻抗,可以表示为屏蔽内部相对于外壳上的电流的纵向电压。该测试方法基于两个阻抗匹配电路。测量原理见图1。被测连接器集成到次级电路02中。激活电磁场的初级电路01的阻抗匹配注入线平行于被测测试样品的表面。该测试适用于测量配有三轴触点的连接器的屏蔽效能,该三轴触点以数据总线系统中使用的屏蔽双绞线电缆端接。注:本标准已被 AECMA 采纳为 EN 2591-212,因此,在未与 AECMA 组织直接协商和联络的情况下不应进行修改。 [外文原描述]: Defines a standard test method for measuring the shielding effectiveness of a connector, or a connector fitted with an accessory and terminated with a cable. The complete assembly has a continuous 360° shielding capability throughout its length. The contents of the corrigendum of April 2003 have been included in this copy.
