Abstract
The utility model belongs to a plane pressure fueling technology, and relates to a transportation 12F type plane pressure fueling connector splash-proof structure. The transportation 12F type plane pressure fueling connector splash-proof structure is characterized in that a splash-proof cover (4) which is in a cylinder shape is fixed on the lower surface of a pressure fueling connector support (2), and an end opening and a sealing end cover (1b) of a pressure fueling connector (1) are surrounded. According to the transportation 12F type plane pressure fueling connector splash-proof structure, the fact that fuel is splashed to accessories mounted in an engine compartment when oil leakage faults happen to the connecting portion of a fueling gun and the end opening of the pressure fueling connector (1) can be avoided, fire hazards are removed, and the safety of a plane is guaranteed.
