本文线束工程师之家主要介绍线束常见三种屏蔽处理的优点与缺点
方案一 单独使用屏蔽线

方法:每个传感器和执行器使用屏蔽线且独立接地文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/
特点:发动机线束有效屏蔽外界干扰,以及对外界的干扰,且发动机线束各导线直接相互独立不会互相感染;文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/
不足:每根屏蔽线需要从ECU处接地,需要ECU模块支持足够多的接地点;文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/
屏蔽线结构由绝缘层+屏蔽层+信号导线+屏蔽层接地导线组成文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/

方法:依靠现有编织技术,在线束分支和主线路使用金属编织的方式;文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/
特点:可靠性强文章源自线束工程师之家-https://www.suncve.com/advantages-and-disadvantages-of-three-common-shielding-treatments-for-wire-harness/
不足:前期投入较大,生产效率较低;线束各传感器和执行器存在互相干扰;
方案三 使用屏蔽波纹管或胶带
方法:在线束外部缠绕屏蔽胶带再使用波纹管;或者直接使用屏蔽波纹管;
特点:有效屏蔽射频干扰;
不足:线束各传感器和执行器存在互相干扰;接地阻抗较大
