摘要: 构造了连接器内接插件间的一个紧邻干扰模型。基于矩量法对模型内单位长度参数进行计算,用传输线法研究了接插件之间的电磁干扰。分析了简化模型对高频干扰的可适用性,给出了干扰的频域结果和时域波形。模拟结果对正确设计、使用电连接器,降低内部电磁干扰有参考价值。

Abstract: A simplified electromagnetic interference (EMI) model is given for a multi-pinsconnector based on the assumption of nearest interaction between pins. Method of moments (MOM) is used in the calculation of per unit length capacitances. Theaccuracy of the model for high frequency signals is discussed. Crosstalk betwenpins are simulated in frequency domain and time domain. Simulating results maybe helpful in the decreasing of EMI in connectors.

Key words: connector, method of moments, electromagnetic interfere, frequency domain, time domain
