Extension Cord with Electromagnetic Radiation-Shielding Function

Abstract

An extension cord includes a body for connecting a two-slot socket to a three-slot socket, a detecting circuit electrically connected to the body for detecting a hot wire and a neutral wire of the two-slot socket, and a grounding circuit electrically connected to the body and mounted between the neutral wire of the two-slot socket and a grounding slot of the three-slot socket. The extension cord further includes a cable covered with a metal wire-weaved net for electrical connection with the two-slot socket. The detecting circuit includes a slide switch and an indicator. The slide switch includes a metal housing. The indicator is electrically connected in series to a resistor. The grounding circuit includes a resettable positive temperature coefficient electric fuse or a meltable fuse.
