Abstract
An air duct connector and an air-cooled refrigerator are provided. The air duct connector includes a first connector, a first guiding structure, a positioning structure, and a second connector. An accommodation space is formed in the first connector, and is provided with an insertion opening. The first connector is further provided with a first air opening. The first guiding structure and the positioning structure are disposed on the wall of the accommodation space. The second connector is provided with a second air opening and a second guiding structure, and is adapted to be inserted, from the insertion opening, into the accommodation space of the first connector. The first guiding structure guides the second guiding structure until the second guiding structure slides to and engages with the positioning structure, such that the second connector is positioned in the accommodation space and the first air opening is connected to the second air opening.
