Abstract

The contact surface of a loose connector has both contact resistance and low inductance, and the inductance depends on the distribution of the true contacts. The contact resistance and inductance were measured by time-domain reflectometry (TDR) for seven contact distribution models. The resistance was approximately constant, while the maximum inductance varied more than twofold depending on the distribution model.
