Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted controllers, in particular to a waterproof structure of a vehicle-mounted controller connector. Background Art

[0002] The on-board controller is one of the core components of the vehicle's electronic system. It is responsible for receiving signals from various sensors, such as vehicle speed, engine speed, oil temperature, tire pressure, etc., and accurately controlling various systems of the vehicle based on these signals. The on-board controller can also communicate with other electronic devices, such as car audio, navigation system, etc., to achieve a more intelligent driving experience. At the same time, it has powerful fault diagnosis functions. When a vehicle fails, it can detect and issue an alarm in time, providing maintenance personnel with accurate fault information for quick troubleshooting. The on-board controller plays a vital role in improving vehicle performance, safety and comfort. The controller connector is an important component in electronic equipment that connects the controller with other components. The vehicle's operating environment is complex and changeable. The car may encounter various weather conditions during driving, such as rainy days, snowy days, and it will also be exposed to a lot of water when washing the car.

[0003] The connection between the existing vehicle controller and the connector is usually waterproofed with sealant. However, during long-term driving, the sealant will gradually fall off due to vibration and high temperature, which greatly reduces the waterproof effect. Moisture can easily enter the controller through the connection between the vehicle controller and the connector, thereby damaging the electronic components inside. It may even put passengers in danger due to controller failure.

[0004] Therefore, we propose a waterproof structure for a vehicle-mounted controller connector. Utility Model Content
