Publication number: 20140253280Abstract: Provided is a reusable fuse having an over-current prevention function. When an over-current that is greater than a reference level is supplied to the reusable fuse and temperature of a positive temperature coefficient thermistor is higher than a specific critical temperature, then an electric resistance of the positive temperature coefficient thermistor increases, a main spring is extended, and thus the spindle is moved toward a side of a housing due to a tensile strength of the main spring and is electrically disconnected from a first lead terminal, thereby continuously blocking flow of current between a second lead terminal and the first lead terminal. When the over-current subsides, then the positive temperature coefficient thermistor is cooled, the tensile strength of the main spring decreases, and thus the spindle is moved toward another side of the housing to be electrically connected to the first lead terminal, thereby allowing the reusable fuse to return to a normal operation state.Type: ApplicationFiled: October 30, 2012Publication date: September 11, 2014Inventors: Duk Hee Kim, Ha Young Park
