Description

Technical Field

[0002] High-voltage connectors play a vital role in modern power transmission and electric vehicle charging systems. As key components connecting power and load, their design and performance directly affect the safety, efficiency and reliability of the equipment. With the rapid development of electric vehicles and renewable energy applications, the demand for high-voltage connectors continues to grow, especially in charging piles and high-power charging equipment, which puts higher requirements on the performance of high-voltage connectors.

[0003] The high-voltage connectors currently used in the market generally use heavy copper wire as a conductor. Although copper has good conductivity, it is heavy, resulting in the size and weight of the entire connector cannot be ignored. In applications such as electric vehicles that are extremely sensitive to weight, overweight connectors will not only increase the energy consumption of the vehicle, but also reduce the overall performance and endurance of the vehicle. In addition, the production cost of copper wire is high and the current carrying capacity is low, which invisibly increases the economic burden of manufacturing high-voltage connectors and puts greater pressure on manufacturers. In addition to material cost and weight issues, the structural design of existing high-voltage connectors often lacks good sealing and shielding performance. High-voltage connectors usually work in harsh environments, including high temperature, humidity or corrosive environments, which makes the internal circuits of the connectors exposed to external factors. The design fails to effectively prevent the invasion of these environmental factors, resulting in the possibility of early failure of the connector. This is particularly prominent in the application of high-voltage connectors at the charging end. If the changes in the external environment are not effectively isolated, it may cause safety hazards during the charging process and even lead to accidents. Summary of the invention
