Abstract

The utility model discloses a failure release indication mechanism of surge protector, which comprises a shell and a release mechanism. The shell is provided with an indication window, below which is an indicator interlocked with the release mechanism. The release mechanism comprises a chip, a first joint plate, a second joint plate, a conducting strip, and a handspike. One polarity of the chip is directly connected with the first joint plate, and another polarity connected with the conducting strip through a low-temperature hard solder. The conducting strip is connected with the second joint plate; the handspike is connected with the conducting strip, and between the handspike and shell is also arranged a release spring exerting release force on the handspike. When the surge protector encounters heat failures, the rising temperature of the polarity of chip will melt the low-temperature hard solder. Under the effect of the release spring, the handspike drives the conducting strip to release from the chip polarity, thus separating the chip of surge protector from the protected circuit. The release mechanism can be interlocked with the indicator to indicate the status of failures. The utility model has the advantages of big release distance, clear indication, and simple structure.

Surge protector fault dropout of the present utility model indicating mechanism is under normal condition, and the two poles of the earth of chip are connected with protected circuit by first joint cover, second joint cover respectively, can play the surge protection effect; When surge protector generation hot stall, the chip heating, the rising of chip electrode temperature can cause the low temperature melts soldering tin; under the effect of dropout spring; push rod drives conducting strip and chip electrode is thrown off, thereby the chip of surge protector and protected circuit are disconnected, and avoids chip overheating to cause fire.After tripping mechanism is threaded off, can move by the interlock indication piece, indicating fault status, the prompting people in time change surge protector.Under the situation that chip electrode is fixed, the dropout spring can drive the rapid and chip electrode disengaging of conducting strip, threads off and opens distance greatly, and reliable in action also can be indicated trip status clearly with the indication piece of tripping mechanism interlock.This dropout indicating mechanism also has simple in structure, and assembling is easy to characteristics.
Preferably, described push rod is provided with pin, and described upward pin extends to the front end of described indication piece, and the front end of indication piece withstands on the side of pin, and the rear end of indication piece is provided with the indication spring.When taking place to thread off, push rod moves under the effect of spring, and last pin and indication piece break away from, and indication piece travels forward, indicating fault status.
Preferably, described push rod is provided with guide chute, and case is provided with the projection that cooperates with described guide chute, and described dropout spring is compressed between projection and the push rod.This projection that cooperatively interacts and chute can play guide effect to the motion of push rod, and the installation for the dropout spring provides condition again.
Preferably, also be provided with down pin on the described push rod.When push rod moved, following pin can touch a signal output apparatus, the output fault indication signal.
Preferably, described push rod is provided with boss, and described conducting strip is provided with the slotted hole that is connected with boss.This syndeton is convenient to assembling.
Preferably, described conducting strip is connected with second joint cover by a flexible conductor.When conducting strip and chip electrode generation dropout, flexible conductor can not interfered the dropout campaign of conducting strip.
Preferably, have the groove of " protruding " font on described first, second joint cover.This groove both can be used for and the chip electrode welding, was convenient to again and the lead riveted.
