AI Technical Summary
Traditional spring-loaded male connectors cannot achieve effective waterproof installation because existing waterproofing processes cannot create a sealed space at the tail of the male connector housing, resulting in unstable signal transmission of the connector under vibration and displacement conditions.
The design adopts a split terminal design. By setting a first terminal and a second terminal inside the male connector housing, the first terminal is first fixed inside the housing, and then welded to the second terminal. The welding cavity is sealed with potting glue to form a closed space. The waterproof connection is achieved by combining the floating cavity and the sealing element.
This design achieves a waterproof connection between the connector and the panel, ensuring the stability and reliability of signal transmission, avoiding the flow problems of potting adhesive, and improving the waterproof performance of the connector.
