Press-Fit PCB Connections Recommended for High-Voltage Vehicle Power Distribution

Würth Elektronik is advocating for the use of PCBs with press-fit power connectors as the preferred interconnection technology for high-voltage power distribution in mobile machines and commercial vehicles. This initiative aims to provide vehicle companies with custom power distribution units that can efficiently handle voltage levels ranging from 60 to 1,000V. The company emphasizes the importance of these units being compact, robust, and easily configurable to meet the diverse needs of the industry.

The implementation of press-fit technology enables the creation of solutions that have demonstrated reliability even in extreme operating conditions. Würth Elektronik highlights that the low contact resistance associated with press-fit connectors results in enhanced current-carrying capacity and minimal heat generation, ensuring optimal performance and safety in power distribution systems.

Moreover, the adoption of press-fit technology is positioned as a time-saving measure during production processes. The incorporation of press-fit screw terminals in distribution units facilitates quick reconfiguration and maintenance tasks, offering flexibility and efficiency in managing power distribution networks within vehicles.

Würth Elektronik's power distribution housings are designed to be corrosion-resistant, sealed, and shielded to safeguard the internal components. The PCBs within these housings can integrate various protective features such as fuses, pre-charge circuits, battery management components, and monitoring systems for current, voltage, temperature, and insulation levels. This comprehensive approach ensures the reliability and longevity of the power distribution units.

According to Ludovic Frelin, the product manager at Würth Elektronik, power distributors play a crucial role in the high-voltage electrical systems of vehicles. Each power distribution unit is tailored to the specific requirements of the vehicle, reflecting the company's commitment to providing customized solutions. Würth Elektronik offers a complete service encompassing electromechanical and electronic design, from initial concept to series production, including hardware and software development, testing, and qualification processes.
