美规插座有UL498;UL1363;UL1449等原则。差别构造;差别形式利用的原则差别。UL498插座部门次要是对构造和常规性测试的要求;此类插座称为Receptacle;UL1363次要是对室内用的耽误线插座的要求;此类插座常简写为RPT(Relocatable Power Tap)。那两者侧重于构造和机械方面的要求。例如;插孔的拉拔力;插孔的尺寸等。而UL1449是对瞬时电压浪涌按捺器的要求;常称为TVSS(Transient Voltage Surge Suppresser);它不单有构造和机械方面的要求;还有相当多电气性能方面的测试。那类插座有三种常见的形式;固定接线型;耽误线型和曲插型。
美规防雷插座UL认证选样规则
1. 样品构造一致,只是插座数量有差别,主测选最多插座孔样品;
2. 假设内部防雷构造纷歧样,那么所有防雷构造均需要选为主测;
3. 假设挈线板带有USB构造,则主测需要增加带USB的型号。
