Description

Technical Field

[0001] The utility model relates to a sealing plug for a charging gun connector. Background Art

[0002] The sealing plug for the charging gun connector is a component used to protect and seal the charging interface in high-voltage charging systems. It is primarily used to seal the charging connector port when the charging gun is not connected, preventing dust, moisture, or other external contaminants from entering the charging interface and ensuring the safety and reliability of the charging equipment. However, in actual use, when the charging gun is connected, the entire sealing plug generally needs to be removed before the cable is connected. This effectively compromises the sealing of the connection point, and the sealing plug's limited functionality makes it inadequate for sealing the cable and connector, resulting in poor compatibility. This is why improvements and optimizations are being developed to address this issue. Utility Model Content
