Aviation plugs are electromechanical components that connect electrical lines, and proper selection and use of aviation plugs is an important aspect of ensuring circuit reliability. The aviation plug generally comprises a plug and a base, wherein the plug is also called a free-end aviation plug, and the base is also called a fixed aviation plug. The connection and disconnection of the circuit are realized by the insertion and separation of the plug and the base, so that various connection modes of the plug and the base are generated. When the aviation plug is applied to a device with pressure inside equipment such as a pressure container and a special-purpose motor, an internal cable needs to be connected with an external cable through an electric connector such as the aviation plug. The base of the aviation plug is fixed outside the related equipment through mounting holes around the square mounting plate of the base by using screws, and the connection position of the external equipment is usually a plane matched with the lower surface of the mounting plate structure so as to ensure the connection stability of the aviation plug and the external equipment. The plug of the aviation plug is connected with an external cable, and when the plug is inserted into the base, the conduction of the internal cable and the external cable of the equipment is realized. The base with the sealing function sold in the market can only bear the internal and external pressure difference of not more than 1bar, and has poor pressure bearing capacity and limited application range. When the applied environment pressure difference is great, the connection is unstable, the leakage of internal gas is caused, and the stable operation is not facilitated.
