“…Abdi and Enjemaa et al tested the insertion force of 6 clamped lamellas in an automotive connector by using laser detection equipment. 9,10 A twisted wire pin is usually made up by many wound beryllium bronze wires. Its irregular structure and the small size result in many difficulties in obtaining accurate dynamic insertion-extraction force by experimental methods.…”

Micro-D electrical connectors are extremely crucial, highly reliable industrial devices in the fields of aerospace, military, and medicine. The geometry and size of the twisted wire contacts of micro-D electrical connector are vital for its mechanical properties and structural stability. In this investigation, dynamics modeling, numerical simulation and experimental tests of the insertion-extraction processes were applied on the twisted wire contacts of micro-D electrical connector.The computer aided design and engineering (CAD-CAE) parameterized models of the twisted-wire contacts were developed, and the theoretical models were also built on the basis of the mechanics of the materials. Nonlinear dynamics simulation was performed by ANSYS/LS-DYNA finite element software to analyze the force and stress distribution of the insertion-extraction processes. The results showed that the insertion force (~0.34 N) was higher than the extraction force (~0.32 N), and the stress concentration occurred on the clamping end and the convex hull of the pin. The mechanical model and numerical simulation were then verified by the experimental tests. By the orthogonal test and the sequential quadratic programming optimization method, the insertion-extraction forces could be reduced to obtain the optimal contacts structural parameters. This theoretical study will help researchers in the design, manufacture, and employment of micro-D electrical connectors.

This paper mainly studies the effect of temperature cycling on stress relaxation behavior of contacts for electrical connectors. Based on the analysis of the test specifications of electrical connectors, this paper provides a kind of test method on stress relaxation behavior of electrical connector contacts under temperature cycling conditions. The detecting circuit is designed; the test is carried out and finally, according to the test data, it can be concluded that 1) for the same temperature change, the absolute change of strain within the temperatures above zero is bigger than that within the subzero temperatures; 2) the deformation of contacts gradually increases as the number of cycles increases. The length of the degradation process for electrical connectors might be related with the high temperature value, temperature variation or temperature variation rate.
