Problems solved by technology

[0012] The present invention is to solve the problem that the existing temperature-sensing power-off protector only has a tripping power-off device that uses contact shrapnel as temperature induction, and cannot effectively set the induction temperature value for power-off, and, when the current is overloaded and overheated, if the contact shrapnel When the trip cannot be performed in real time, the trip is incomplete or cannot be tripped, the circuit will continue to conduct, sparks will be generated in the circuit or the power will be turned on and off repeatedly, resulting in unstable current, causing the electronic product to crash or fail to operate normally, and shorten the service life. Problems ranging from complete damage to

Abstract

An electric circuit protector of double temperature induction cut-off type is featured as setting contact flexure strip and thermal cut-off unit between two contact terminals on circuit loop to form two temperature induction cut-off units being operated independently, bending contact flexure strip towards opposite direction for tripping it off by deformation caused by heat to cut-off circuit first or otherwise rising temperature up continuously to melt fuse block to cut off circuit when current is overloaded and circuit is overheated.

Description

technical field [0001] The present invention relates to a circuit protector with double temperature induction power-off, which is provided with a contact shrapnel and a thermal cut-off device in the circuit loop to form two independently operated temperature-induced power-off devices; When overheating or the use environment temperature is too high, the contact shrapnel is heated and deformed and reversed to bend and trip, or the fusible block of the thermal fuse device is melted and broken, so that the circuit circuit of the thermal fuse device is tripped and separated into a circuit breaker ( OFF) state. Background technique [0002] The use of electricity has become an indispensable part of modern human society. The equipment that uses electricity surrounds the surroundings of life, especially the computerized and informationized industries, homes, transportation, education, entertainment, etc., without electricity. [0003] The use of electricity and its equipment has cr...
