However, increasing performance requirements (e.g., operation at elevated temperatures) and regulatory restrictions are prompting a reassessment of lubricant selection. In this study, the influence of three lubricants (one oil and two greases), operating temperature (room temperature and 130°C), and applied volume (low, medium and high volume) on electrical contact resistance (ECR) and coefficient of friction (CoF) is investigated by means of fretting wear tests on silver-plated contacts. The results show that unlubricated silver contacts exhibit a longer stable phase at 130 °C than at room temperature. For lubricated contacts, service life is influenced by both temperature and lubricant volume. Certain lubricants demonstrate earlier fail at room temperature than at elevated temperatures. The findings highlight the importance of careful selection and optimization of lubricants for electrical connectors under varying environmental conditions.}}, author = {{Blauth, Michael and Tülling, Sören and Song, Jian}}, booktitle = {{Proceedings of the 70th IEEE Holm Conference on Electrical Contacts (HLM)}}, isbn = {{979-8-3315-5997-7}}, issn = {{2158-9992}}, keywords = {{Connectors, Resistance, Silver, Lubricants, Contacts, Oils, Friction, Corrosion, Optimization}}, location = {{San Antonio, TX, USA }}, publisher = {{IEEE}}, title = {{{Effect of Operating Temperature and Application Quantity of Lubricants on the Fretting Behavior of Silver Plated Electrical Contacts}}}, doi = {{10.1109/hlm51652.2025.11278329}}, year = {{2025}}, } @misc{6257, author = {{Kuckkuck, Carsten and Lödige, Pascal and Blauth, Michael and Yuan, Haomiao and Song, Jian}}, booktitle = {{IEEE Transactions on Components, Packaging and Manufacturing Technology}}, publisher = {{IEEE}}, title = {{{Analysis of the Inter Strand and Strand/Connector Resistance Relations in Wire Connection Systems}}}, doi = {{10.1109/TCPMT.2020.3005075}}, year = {{2020}}, } @inproceedings{6293, author = {{Kuckuck, Carsten and Blauth, Michael and Song, Jian}}, booktitle = {{Tagungsband der VDE/VDI-GMM-Fachtagung „Symposium Connectors“}}, location = {{Lemgo}}, pages = {{28 -- 44}}, title = {{{Einfluss der Kompression und der Leiterkontaktierfähigkeit auf die elektromechanische Kontaktierung von Crimpverbindungen}}}, year = {{2019}}, } @inproceedings{6322, author = {{Kuckuck, Carsten and Blauth, Michael and Song, Jian}}, booktitle = {{Proceedings of VDE-Fachtagung Albert-Keil-Kontakt-Seminar}}, location = {{Karlsruhe}}, pages = {{54 -- 62}}, title = {{{Differentielles Widerstandsmodell zur Beschreibung des elektromechanischen Kontaktverhaltens von Crimpverbindungen}}}, year = {{2019}}, } @inproceedings{6329, author = {{Kuckuck, Carsten and Blauth, Michael and Song, Jian}}, booktitle = {{Proceedings of the 64th IEEE Holm Conference on Electrical Contacts}}, location = {{Albuquerque, USA}}, title = {{{Investigations on the Effects of Different Strand Surface Conditions on the Inter Strand and Strand/Connector Resistance}}}, year = {{2018}}, } @phdthesis{13452, abstract = {{Im Rahmen dieser Arbeit wird die konstruktive Auslegung von Steckverbindern hinsichtlich der Stromtragfähigkeit untersucht.

Zudem werden Sensitivitätsanalysen durchgeführt, um den Einfluss konstruktionsrelevanter Parameter auf die Stromerwärmung von Steckverbinderkontakten darzustellen. Durch die gewonnenen Ergebnisse wird schließlich ein Vorgehen zur systematischen Auslegung von Steckverbinderkontakten hinsichtlich der Stromtragfähigkeit erarbeitet.

The purpose of this study is to develop an analytical model which describes the electricalthermal behaviour of electrical contact systems. Established mechanical, electrical, thermal and contact physical relations are combined to design the analytical model. Differential equations with appropriate boundary conditions are used to solve the heating problem. The various parts of an electrical connector represent separate subsystems. The geometry, the material properties and the heat transfer coefficients for the contact system, the terminal clamp and the wire have been taken into account. These different subsystems have been connected to obtain the overall temperature distribution. In order to verify the analytical model, contact systems made of three copper alloys with different electrical and thermal properties are investigated experimentally at various current loads. It was shown that the analytical model can predict the temperature rise for simple geometry well. Using the analytical model several parameters can be easily changed. Moreover, the main influencing factors and their relationships can be identified directly on the equations.
