Long-Term Behavior of Clinched Electrical Contacts

Joining by forming operations presents powerful and complex joining techniques. Clinching is a well-known process for use in sheet metalworking. Currently, clinched joints are focusing on mechanically enhanced connections. Additionally, the demand integrating electrical requirements to transmit currents will be increased future. This integration particularly important, instance, e-mobility sector. It enables connecting battery cells with of aluminum copper. Systematic process-specific advantages this method opens up possibility find create electrically optimized The optimization transmission demonstrated adapting tool geometry joint design. Based comparison resistance, limit temperature defined materials used based microstructural condition aging due artificial aging. As result investigations carried out, reliable current at constant conductor 120 °C can achieved copper–copper joints. In case pure mixed copper, long-term stable ensured 100 °C.
