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.

Many types of electrical connectors are used in traditional and emerging technology sectors such as electric vehicles, traditional automobiles, and aircraft, in which they need to maintain a stable and low electrical contact resistance (ECR). However, external shock and vibration can cause a sudden increase in ECR, which can lead to system failures due to electrical discontinuities or power transfer loss. In this study, the impact of structural dynamics on the ECR response is investigated using an analytical modeling and simulation. A structural vibration of 100 Hz with a surface displacement amplitude of 3 nm is applied to an electrical connector system, and the dynamic ECR response is analyzed with respect to the structural stiffness and damping ratio. At the onset of structural vibration, the system shows a high frequency ECR response with large amplitude variation, which decays over the elapsed time. From the parametric simulations and statistical data analysis, it is observed that the magnitude of ECR fluctuation decreases with the structural stiffness and damping ratio. Within the tested range of structural properties, the ECR fluctuation is more sensitive to the stiffness than the damping ratio.

“…The function of electrical connection and disconnection during mechanical insertion and extraction operations for electrical connectors is mainly determined through a large number of contacts integrated into the internal insulation. An unsuitable insertion/extraction force could lead to many failures, including, but not limited to, loose contact and instantaneous, even permanent, disconnection [2,3].…”

An electrical connector is an important component for achieving the interconnection of electric equipment. However, the degradation of contacting parts within the electrical connector under repetitive mechanical insertion and extraction operations causes a decrease in the contact reliability level, resulting in considerable safety hazards. The coating quality, determining the degree of degradation of contact pairs, is considered a critical factor in fabricating more reliable and safer electrical connectors. In this paper, a gold and nickel coating is deposited onto the surface of a pin within an electrical connector using magnetron sputtering and is compared to an electroplated pin, and the effects of different processing techniques on the microstructure, mechanical properties, and wear behavior are systematically investigated. The measurement results indicate that the surface quality (uniformity and defect density) and mechanical properties (hardness and elastic modulus) of the gold/nickel coating based on magnetron sputtering are significantly better than those achieved using electroplating, showing excellent wear properties and electrical contact stability after repetitive insertion–extraction operations. This study is critical for the development of advanced coatings using a novel deposition technique.
