一种可去除脉冲电流的接插件装置 技术领域
本公开一般涉及汽车配件领域，尤其涉及一种可去除脉冲电流的接插件装置。
背景技术
汽车接插件是我们电子工程技术人员经常接触的一种部件。它的作用非常单纯：在电路内被阻断处或孤立不通的电路之间，架起沟通的桥梁，从而使电流流通，使电路实现预定的功能。电子及电气产品的电磁干扰发射或受到电磁干扰的侵害都是通过产品的外壳、交/直流电源端口、信号线、控制线及地线而形成的。按照EMI的传播方式，可将其分为电磁辐射干扰和电磁传导干扰两大类。通常，辐射干扰出现在产品周围的媒体中，传导干扰则出现在各种导体中。一般来说，通过外壳发射的电磁干扰，或通过外壳侵入的干扰都是辐射干扰，而通过其它导体发射和入侵的干扰属于传导干扰。
抗EMI系统设计技术是提高电子整机EMC性能的关键所在。因此该技术又称为EMC设计技术。EMC设计的目的是使电子、电气产品在一定的电磁环境中能正常工作，既满足标准规定的抗干扰极限值要求，在受到一定的电磁干扰时，无性能降级或故障；又满足标准规定的电磁辐射极限值要求，对电磁环境不构成污染源。因此，EMC是产品的重要性能之一，也是实现产品效能的重要保证。
