The connector studied herein is a self-ejecting microconnector that features a circular compression spring. This type of circular connector ensures reliable connections for systems requiring reduced weight and miniaturization. Being implemented in various military and aerospace applications, the connector is liable to undergo extreme vibratory loadings and shocks; but even in more common applications (medical sensors, power control systems, communications, etc.) the manufacturer has to guarantee that the two ends will remain properly assembled to ensure electrical continuity. The main purpose of this work is to simulate the whole insertion-extraction process using the finite element method (FEM) and to optimize the ejection force required to unplug the connector. The shape of the groove machined on the male part of the connector is investigated, allowing determination of the geometric parameters of interest. Results will provide manufacturers with useful data, which may also help their customers choose their interconnection solution.
