摘要

采用全波三维仿真工具，对汽车系统机压线对线同轴连接器的不同设计方案进行了分析。仿真结果证明了该方法能有效降低电磁干扰、阻抗失配和电压驻波比。通过消除不必要的间隙并在外壳中插入气隙，提高了汽车系统线对线同轴连接器的信号完整性。所提出的线对线同轴连接器可用于延长汽车系统内的射频电缆，同时减少EMI和阻抗失配。此外，提出的机压连接器设计将降低汽车系统所需的同轴连接器的总成本。

Signal integrity analysis of machine pressed coaxial connector for automotive system

Different designs of machine pressed wire-to-wire coaxial connectors for automotive system are proposed and analyzed using a full wave 3D simulation tool. Reduced electromagnetic interference (EMI), impedance mismatch and voltage standing wave ratio (VSWR) are demonstrated using the simulation results. By eliminating unnecessary gaps and inserting air gaps in the housing shells, the signal integrity of wire-to-wire coaxial connectors for automotive system is improved. The proposed wire-to-wire coaxial connector can be used to elongate the RF cables within the automotive system with reduced EMI and impedance mismatch. Moreover, the proposed machine pressed connector design will reduce the total cost of coaxial connectors required for automotive systems.
