Fig. 1 is structural representation of the present invention.
Fig. 2 is the stereogram of piezo-resistance of the present invention and tripping gear.
Fig. 3 is the view of piezo-resistance of the present invention and tripping gear.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to Fig. 1, piezoresistor type surge protection device, comprising: the pedestal 1 in " recessed " type; terminals 2 are positioned at the both sides, inside of pedestal 1; wire insert port 3 on position alignment pedestal 1, terminals 2 comprise conductive strips 4 and external wire are fixed the screw 5 on conductive strips 4
Nested WFTA module 6 in nested pedestal 1, is packaged in the piezo-resistance 7 of nested WFTA module 6, and arranges the tripping gear 8 of piezo-resistance 7 side,
Tripping gear 8 comprises a unhook bonding pad 8a, an one unhook pin 8b and unhook cap 8c, unhook cap arranges the top of 8c tripping gear 8, unhook bonding pad 8a soldered is between the first pin 7a and unhook pin 8b of piezo-resistance 7, unhook pin 8b connects with the first conductive strips 4a being connected the first terminals 2a, second pin 7b of piezo-resistance 7 connects with the second conductive strips 4b being connected the second terminals 2b
Below unhook bonding pad 8a, be provided with Compress Spring 9, time unhook bonding pad 8a soldered is between the first pin 7a and unhook pin 8b of piezo-resistance, Compress Spring 9 is in most compressed state.
And Compress Spring 9 is sheathed on the mobile jib 10 in tripping gear 8, mobile jib 10 is packaged in unhook shell 11, unhook shell 11 is made for insulating material, the below of Compress Spring 9 connects a sensitive switch 12, once Compress Spring 9, unhook bonding pad 8a is flicked, Compress Spring 9 unclamps the switch of sensitive switch 12, and sensitive switch 12 just action, by the signal transmission of action to signal receiving end 13.
With reference to Fig. 2 and Fig. 3, 8b is one-body molded for unhook pin, comprise the welded plate 14 of one and unhook bonding pad 8a soldered, and the pin bayonet socket 15 of insertion first conductive strips 4a draw-in groove of end is set, pin bayonet socket 15 is identical with the structure of the second pin 7b of piezo-resistance, all in " V " type, include the straight plate 15b of the first straight plate 15a and second, the junction of the straight plate 15b of the described first straight plate 15a and second bends and is connected smoothly, above the described second straight plate, 15b connection one and the second straight plate 15b are the 3rd straight plate 15c of 100-120 angle angle, and the straight plate 15b of the first straight plate 15a and second forms an elastic force, the draw-in groove of energy stuck fast first conductive strips 4a.
