Transformerless charger with terminal safety features

Abstract

It is an object of the present invention to provide a transformerless charger capable of preventing a human body from receiving an electric shock from a charging terminal, and of making it easy to clean the charging terminal. In order to achieve this object, the transformerless charger of the present invention comprises: a charging terminal for supplying charging voltage to rechargeable electronic equipment; a transformerless power supply circuit for supplying charging voltage to the charging terminal; a flip cover that covers the charging terminal to prevent the charging terminal from being exposed; and a switch that allows or blocks the passage of a current between the charging terminal and the transformerless power supply circuit in synchronization with an opening or closing motion of the flip cover. This configuration makes it possible to control the passage or blocking of a current at the charging terminal in response to the open or closed state of the flip cover, and therefore, it is possible to secure safety to prevent a human body from receiving an electric shock via the charging terminal and it is also possible to easily clean the charging terminal.
