[0002] With the booming development of the global electric vehicle industry, automotive electrical connectors, as key components for power transmission and signal interaction, have become an emerging hot spot in the field of connector applications. Among them, high-current shielded connectors installed on battery packs are an indispensable core component in the power system of new energy vehicles. Driven by both intensified industry competition and the need to control vehicle costs, the market has put forward more stringent requirements for electrical connectors. They not only need to further reduce size and cost, but also need to significantly improve performance to meet the growing application needs of new energy vehicles and energy storage systems.

However, the high-voltage connectors currently on the market still have the following problems:

[0004] 1. Traditional high-voltage connectors have significant limitations in installation flexibility, as they only support 90° or 180° mating methods. In the compact and space-constrained environment of new energy vehicles, flexible installation is difficult to achieve, which not only limits the choice of installation location but also brings great difficulties to the vehicle wiring, increasing installation and time costs.

[0005] 2. Existing 360° shielding structures are prone to loosening and breakage of the shielding layer when facing complex vibration environments, resulting in rapid attenuation of shielding effectiveness, inability to effectively resist electromagnetic interference, and affecting the stability of system signal transmission.

[0006] 3. The rudimentary design of the signal interlock waterproof structure results in the existing high-voltage connectors generally having a waterproof rating lower than IP67, making it difficult to work stably for a long time in complex environments such as rain and humidity, and posing safety hazards such as leakage and short circuit.
