Title:
REPEATABLE FUSE FOR HIGH CURRENT
Document Type and Number:
WIPO Patent Application WO/2013/085265
Kind Code:
A1
Abstract:
The present invention relates to a repeatable fuse for high current. The repeatable fuse includes: a housing provided with an inner space and a first lead terminal disposed on one side surface of the housing; a second lead terminal disposed on the side surface of the housing, wherein the second lead terminal is spaced from the first lead terminal; a movable contact plate disposed within the housing and electrically short-circuited with the housing, wherein the movable contact plate is electrically switched on-off with the first lead terminal or the first and second lead terminals; main and bias springs disposed within the housing, wherein the main and bias spring electrically switch on-off the first lead terminal and the movable contact plate or the first and second lead terminals and the movable contact plate; and a positive temperature coefficient thermistor inserted into the housing, wherein the positive temperature coefficient thermistor is electrically connected to the first and second lead terminals. The positive temperature coefficient thermistor includes a positive temperature coefficient device in which electric resistance increases at a temperature greater than a special critical temperature. The movable contact plate may be linked with the tension forces of the main spring and bias spring. That is, the movable contact plate may be linked to move in the direction in which the main spring and the bias spring are extended or compressed, thereby being electrically connected to or short-circuited with the first lead terminal or the first and second lead terminals.
