New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
[0003] In actual use, new energy vehicles are driven by electricity to move as a whole. In actual use, more wires are often needed to connect them. However, in actual use, seals need to be added at the connection points. A Chinese patent discloses an AC conductive seal structure for a new energy electric drive system (authorization announcement number CN211700756U). This patented technology can achieve a sealing effect on the connection part of the device by setting a first sealing ring and a second sealing ring, which has the advantage of being waterproof. At the same time, the device is provided with a buckle, so that the connection of the device is tighter, ensuring the sealing effect and the stability of the use of the device.
[0004] Although the device can be sealed by the sealing ring during actual use, the access of the wire during actual use causes the sealing ring to be incompletely sealed, thereby affecting the actual use and failing to meet the actual use needs.
[0005] In order to solve the above problems, we have made improvements and proposed special-shaped seals for use in new energy electric drive systems. Utility Model Content
