Description

Technical Field

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle-mounted power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. The inverter is the "brain" of new energy vehicles, and it needs to communicate with controllers such as motors, parking, and the entire vehicle. Therefore, the low-voltage connector of the inverter needs to lead out wiring harnesses in multiple directions. Conventional automobile inverters are equipped with multiple low-voltage connectors, and the low-voltage connectors include plugs and sockets. However, the plug and socket structure used in common low-voltage connectors has poor structural connection stability and is prone to loosening after long-term use. In addition, the sealing effect between the connected structures is poor. When water flows from one end to the connection between the plug and the socket, it is easy to cause a water short circuit. For this reason, this application proposes a low-voltage connector for a new energy vehicle controller. Utility Model Content
