The sealing airbag 15 is made of elastic material, for example, the sealing airbag 15 is made of high-quality rubber, and is provided with filling liquid inside. It also includes an adjustment mechanism for extracting and injecting the filling liquid inside the sealing airbag 15. The adjustment mechanism includes a liquid passing tube 12 located inside the second plug-in tube 101 and arranged parallel to the axis of the second plug-in tube 101.

[0046] The seal of this structure adopts a variable diameter sealing structure, which increases the contact area and extrusion pressure between the first plug-in tube and the second plug-in tube, thereby greatly increasing the sealing effect of the first plug-in tube and the second plug-in tube, improving the sealing performance of the connector, and being able to cope with the vibration generated by the car during driving. The filling liquid can not only absorb the vibration, but the sealing airbag also has good elasticity. Therefore, the sealing effect is still guaranteed under the vibration environment of the car, and the sealing effect will not deteriorate with time.
