[0002] Currently, high-voltage connectors in new energy vehicles are crucial components in electrical systems. They are electrical connection devices used to carry high voltage and high current, responsible for transmitting electrical energy and signals between various high-voltage components in the vehicle. They are widely used in high-voltage power distribution devices such as high-voltage battery packs, motors, inverters, and chargers in new energy vehicles.

[0003] Many components in high-voltage connectors are connected by fasteners. Although this connection structure is convenient and allows for easy assembly and disassembly of the two components, this connection method requires additional materials (bolts, screws, nuts, and other fasteners), and then aligning the fasteners with the connection holes of the two components before tightening the connection. This makes the assembly process of high-voltage connectors more complicated, resulting in higher equipment costs and lower production efficiency. Summary of the Invention
