Abstract
A waterproof casing for a power supply has a lower casing, an upper casing, an inlet cover and an outlet cover. The lower cover contains electronic components. The upper casing is mounted on the opening of the lower casing and has an inlet cavity, at least one inlet, an outlet cavity and at least one outlet. The at least one inlet and outlet are formed through the upper casing and respectively communicate with the inlet cavity and outlet cavity. The inlet cover and outlet cover respectively seal the inlet cavity and the outlet cavity, communicate the inlet cavity and the outlet cavity with the lower casing to allow the air to flow inside the casing and to keep the water from flowing in the inlet cavity and the outlet cavity. Structure of the waterproof casing is simplified, so benefits manufacturing.
