Claims

[Claims for Utility Model Registration] 1. A high-voltage energizing plug protruding from the side of the main body, and a low-voltage connection electrode provided on the side of the main body to which the low-voltage plug is removably connected. a low-voltage outlet; a step-down device housed in the main body and connected between the high-voltage energizing plug and the low-voltage connection electrode to step down a high voltage to a low voltage; 1. A voltage conversion adapter comprising: switch means disposed near the insertion port for controlling opening and closing of the step-down device by inserting and removing the low voltage plug into the low voltage insertion port. 2. The switching means consists of a contact connected to the step-down device and a contact connected to the high-voltage energizing plug, both contacts being spaced apart from each other on a line where the plug pieces of the low-voltage plug are layered, and The voltage conversion adapter according to claim 1, wherein the inserted plug piece is disposed at a position where it can be contacted. 3. The switch means includes a pressing member whose one end is always projected from the side surface of the main body on the insertion port side by a biasing member and supported so as to be able to reciprocate in the insertion direction of the low voltage plug, and which is driven to open and close by the pressing member. The voltage conversion adapter according to claim 1, wherein the voltage conversion adapter comprises a switching contact.
