The present invention relates to an anti-compression air-tight seal aviation electric connector. The electric connector comprises a socket and a plug, the socket comprises a round base and a protective cover, the round base comprises a flange, a connecting sleeve and a thread bush which are connected to an integrated structure, the round base is internally provided with a first contact, the firstcontact comprises a guide sleeve and an inner sleeve which are connected to an integrated structure, a hole cover plate is arranged between the inner side of a first seal body and the guide sleeve, asecond seal body is arranged between a hole insulator and the inner wall of the thread bush, the plug is internally provided with a plurality of second contacts, the second contacts and the first contact are internally provided with wire spring jacks, the protective sleeve is internally provided with a limited pillar, the end portion of the limited pillar is arranged in the wire spring jack of thefirst contact, and a rubber mat is arranged between the external portion and the thread bush. The anti-compression air-tight seal aviation electric connector is convenient and rapid in operation andinstallation, good in compression resistance and seal insulation performances, and low and stable in contact resistance, can still remain high-reliability electric contact performances in a strong vibration impact environment, is small in insertion and extraction force and low in wearing, can be suitable for various field of working condition environments with high pressure, high vacuum and high gas tightness.
