“…Considering that the accelerated life test is spend too much time for product with high reliability and long life. In order to fully utilize the performance degradation data, DuanK, Zhu F, Li Y [13] researched the relationship between contact stress shrinkage range and contact resistance based on ANSYS. Li Y, Zhu F, Chen Y [14] used ANSYS software to model the insertion force between the contacts, specific measures to improve the contact reliability of electrical connectors.…”

The reliability of the fatigue life of the contacts part of the electrical connector is an important aspect of the mechanical equipment reliability. Aiming at the reliability problem of fatigue life of 450 series multi-purpose spring electrical connector contacts part, A fatigue life calculation method based on ABAQUS/FE-SAFE for the contacts part of the electrical connector is proposed. By establishing a threedimensional model of the contacts part of the electrical connector, the finite element software ABAQUS can be used to calculate the contact performance during the single insertion and removal of contacts. According to the stress state of the contact, the physical model of fatigue failure of the contact is established. Then the joint fatigue analysis software FE-SAFE is used to establish the simulation calculation model of the fatigue life of the contact, and the fatigue life of the contact can be inferred. The paper proposes a reliability calculation method for contacts part to prevent major safety accidents caused by contact failure. It is of great practical significance to guide the design, processing and inspection of electrical connector contacts part.

“…Therefore, the analysis of the insertion-extraction forces of the connector attracts considerable attention by numerous researchers. 5 Duan and Zhu et al studied the influence of the structure parameters on shrink range [6][7][8] through simulation experiments and analysis of the insertion force of an N-type electrical connector. Abdi and Enjemaa et al tested the insertion force of 6 clamped lamellas in an automotive connector by using laser detection equipment.…”

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.

“…Although the contact pressure is not measured experimentally, we can assume that the connection pressure between the electrodes results from the elastic restoring force of the adhesive. The experimental and mathematical investigations in this study indicate that the real contact area allows for electrical conductance because the two metals are in contact with each other over some of the apparent contact area [51][52][53][54][55][56]. Thus, the film-type connector forms a plate-to-plate contact between the electrode and the connecting unit, which ensures the maximum apparent and real contact areas.…”

With the escalating demands for downsizing and functionalizing mobile electronics, flexible electronics have become an important aspect of future technologies. To address limitations concerning junction deformation, we developed a new connection method using a film-type connector that is less than 0.1 mm thick. The film-type connector is composed of an organic film substrate, a UV-curable adhesive that deforms elastically under pressure, and electrodes that are arranged on the adhesive. The film-type connection relies on a plate-to-plate contact, which ensures a sufficient contact area. The electrical reliability of the film-type connection was investigated based on changes in the resistance during bending at curvature radii of 70, 50, 25, 10, 5, and 2.5 mm. The connection was bent 1000 times to investigate the reproducibility of the connector's bending properties. The tests showed that no disconnections occurred due to bending in the vertical direction of the electrode, but disconnections were observed due to bending in the parallel direction at curvature radii of 10, 5, and 2.5 mm. In addition, the maximum average change in resistance was less than 70 milliohms unless a disconnection was generated. These results support the application of the new film-type connection in future flexible devices.
