For high-voltage connectors for electric vehicles, with the development of the market, the performance requirements of OEMs for product protection are also constantly improving. In the early stage of industry development, the protection requirements of IPI67 can already meet the vast majority of customers. However, in the later period, with the failure of protection of connector products on the market, there are more and more cases of water leakage, insulation failure, and even ablation.
The gradual improvement of protection requirements has become the development trend of electric vehicles. At present, the requirements of IP67 cannot meet the normal use requirements. Of course, this is not absolute, and it depends on the position of the connector on the vehicle.
