Abstract
An arc discharge prevention structure of a socket for preventing continuous occurrence of an arc discharge which can result in a fire, by using a configuration for deflecting an arc to avoid damage to a contact is provided. At least part of a pair of permanent magnets that forms a magnetic field for deflecting an arc in a connection/disconnection area where a plug pin and a socket contact are connected and disconnected is located in an opening surface side of a socket housing in which a plug insertion hole is opened. A magnetic body of the plug is attracted to bias the plug pin to a connection position where the plug pin is hot connected to the socket contact.
