  • Understanding plug holders

    The plug bracket is a plug built-in accessory for connecting the power cord. Two pin plug support: there are two round pins, which only connect the front (L) and zero line (n), and it is used for non grounding. General pin dimensions are: 4.0mm, 4.8mm and 5.0mm. Generally, the plug support produced by our factory is also relatively complete, including European plug support, American plug suppor...

  • Why are there many types of plug and socket?

       世界各国国情不同,输电距离不同,用电量各异,这就导致了各国电压不同,不过基本都为220V,50HZ,当然也有其他电压:110V、120V、240V的,电压不同,那么插座规格肯定也就不一样了。

    总的来说高压使用效率更高,低压安全。


    插头形状:矩形、柱状,截面大、耐受大电流;三角形:可以防止异物插入或者防止误插入,接入地线保护,保证安全;两角形:供电稳定,使用方便;

     

       国际电工委员会指出,全世界共有15种各式各样的插头,各国的电压也不相同。出门在国外要想使用电子设备,经常会遇到插头插座不适配的问题。为什么世界各国没有统一的插头插座呢?

      插座诞生于一个尚未全球化的世界,这是世界各地插头型号不统一的主要原因。据介绍,插头的最初概念是美国发明家...
