And the tripping gear that piezo-resistance one side is set, described tripping gear comprises a unhook bonding pad that pin and the terminals of piezo-resistance are interconnected, and the flexible member that unhook bonding pad below is set, flexible member applies one so that the unhook bonding pad breaks away from the active force of pad to the unhook bonding pad all the time.
Preferably, described tripping gear also comprises a unhook pin, and unhook bonding pad soldered is between the pin and unhook pin of piezo-resistance, and the unhook pin connects with the conductive strips that are connected terminals.
Preferably, described flexible member below is provided with sensitive switch, in case when flexible member flicked the unhook bonding pad, sensitive switch just moved, the signal that moves is passed to signal receiving end.
Preferably, described flexible member is a Compress Spring, is looped around on the mobile jib that is packaged in the tripping gear, can move up and down at mobile jib.
Preferably, described unhook pin is one-body molded, comprise one with the welded plate of unhook bonding pad soldered, and the pin bayonet socket that the insertion conductive strips draw-in groove of end is set.
Preferably, described pin bayonet socket is " V " type, tightly buckle conductive strips draw-in groove.
Preferably, described pin bayonet socket comprises the first straight plate and the second straight plate, and the described first straight plate and the second straight plate are connected smoothly, and connects the 3rd straight plate that the one and second straight plate is 100-120 angle angle above the described second straight plate.
Preferably, described piezo-resistance also is provided with a distant news device, and by the signal brace temperature or the current status of piezo-resistance is passed to signal receiving end.
By technique scheme, the invention has the beneficial effects as follows:
When piezo-resistance is subject to extraneous very large interference, the temperature of piezo-resistance raises, because the unhook bonding pad is soldered, then pad melts, Compress Spring flicks the unhook bonding pad in installing fully, thereby so that equipment and electric power system are out of touch, security performance is high, simple in structure, easy to use.
