But we believe that the application of metal alloy casings will become more and more popular in the future. Although the cost of metal material connectors is higher than that of nylon materials, their strength is higher, and there will be no cracking or breakage after impact on the plug-in; at the same time, the fast charging function requires that the connector can withstand higher in a short time. The good thermal conductivity of metal materials is conducive to better temperature control, so we believe that metal casings will become more and more popular in future applications. It may also be based on the above considerations that Tesla’s Model Y has replaced its high-voltage connector housing from plastic material with metal material.
