Abstract: An electric connector and a movable platform are provided. The electric connector includes a housing, a circuit board, and an electric connection part. The circuit board is arranged in the housing to connect to a load of the movable platform. The electric connection part is displaceable relative to the housing, and at least one portion of the electric connection part may extend out of the housing. A sealing ring may be provided in an outer peripheral surface of the electric connection part that extends outside the housing to seal the gap between the electric connection part and the casing of the movable platform, so as to isolate the circuit board of the housing. The electric connection part may be electrically connected to the circuit board and an external battery respectively to enable the circuit board to process electrical signals output from the battery.

Abstract: A lens limiting assembly includes an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction, and a locking ring including a flange configured to abut against the elastic arm.

Abstract: An unmanned aerial vehicle (UAV) includes a heat dissipation device, an inertial measurement unit (IMU), and a control module. The heat dissipation device includes an air guiding cover and a heat conduction plate. The air guiding cover includes an air duct configured to guide an airflow, and the heat conduction plate directly constitutes a portion of a sidewall of the air duct. The IMU module is received within the air duct. The control module is located outside the air duct and disposed at a side of the heat conduction plate that faces away from the IMU module. Heat generated by the IMU module is taken away directly by the airflow within the air duct.
