The invention belongs to the technical field of helicopter structural parts, and particularly relates to an external plug protection cover of a helicopter. The external plug protection cover is characterized in that lug pieces (1) used for installation are arranged at the two ends, the lug pieces (1) are connected with outer skin of the helicopter through installation holes (3) by means of rivets, the protective cover is fixed on the helicopter, an opening for plugging and pulling a plug is formed in the front end of the protective cover, and a small lower edge (2) is designed at the opening.
Description
technical field [0001] The invention belongs to the technical field of helicopter structural parts, in particular to a protective cover for a helicopter external plug. Background technique [0002] Most of the current helicopters need to perform multiple tasks, such as installing photoelectric pods and search lights. Since these two devices are installed on the external pylons on the left and right sides of the helicopter nose, their cables must pass through the fuselage skin to communicate with the helicopter. The internal control box is connected. This requires an adapter plug to be installed on the skin of the fuselage to facilitate the connection of internal and external cables and facilitate the disassembly and maintenance of the equipment. However, since the plug is directly exposed, it is easily corroded by rain and snow, which greatly reduces the service life of the external plug. Contents of the invention [0003] The technical problem to be solved in the presen...
