Four-channel breakout connectors can power multiple devices through a single connector, reducing wiring, reducing costs, and embodying innovation. Different OEMs may take different approaches to design decisions based on the architectural characteristics of their respective vehicles. Another important consideration is to ensure that the connector can withstand high frequency vibration. What worries engineers is that over time, vibration can cause microwear at the terminal connections, increasing resistance. Consumers expect EVs to last longer and have fewer moving parts to wear than internal combustion engine vehicles, so connectors also need to be more durable.
