ELECTRICAL CONNECTOR HATCH Russian patent published in 2022 - IPC F41F3/55 

FIELD: aviation; rocket engineering.

SUBSTANCE: invention relates to aircraft and rocket engineering, mainly to devices for disconnection of electrical communications of missile with launching device. Electrical connector hatch comprises a housing and an electrical connector for docking with a launching device, located in the lowering on the surface of the aircraft, cover and lever rigidly connected to it by one end and connected by the other end to axis of rotation of hinged joint fixed on surface of aircraft. At that, hinged joint is made of two parts arranged at side walls near front wall of cover, and the cover is connected to the axis of rotation of the corresponding part of the hinge joint by a separate lever and is made of front and rear parts connected to each other by a hinge joint by means of a cylindrical axis, on which there is a torsion spring parallel to axes of attachment of levers. Hatch is equipped with parallel side walls perpendicular to axes of hinged joints and made on side of inner surface of housing, along which symmetrical longitudinal guide slots are made, with increase in their distance from the outer surface of the housing as they approach the rear part of the side walls. Rear part of cover is equipped with brackets parallel to side walls of hatch, equipped with coaxial cylindrical slides arranged in symmetrical longitudinal guide slots of side walls of hatch. On the side of the outer surface of the rear part of the cover there is a recess for a tool for opening the cover, hatch is equipped with a collet lock of the open position of the hatch, connected by a flexible connection to the starting device, and in the front part of the hatch body, in front of the electrical connector, there is a seat for a collet lock.

EFFECT: device is aimed to reduce the height of the cover protrusion above the aircraft surface in its open position, reduction of drone aerodynamic resistance during joint flight in atmosphere with carrier aircraft, improved sealing of the cover due to the possibility of using the proposed device on unmanned aerial vehicles separated from the launching device with large dimensions of the electrical connector.
