Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
As it can be seen, piezoresistor type surge protection device described in the utility model, including in pedestal 1, nested pedestal 1
Nested WFTA module 2, the varistor being packaged in nested WFTA module 2 and be arranged on the tripping gear of nested WFTA module 2 interior side, described
Tripping gear includes insulating slide 3, insulation slide block 4, break off relations welding sheet 7 and compression spring 6, and described insulating slide 3 is fixing to be connected
In the side within nested WFTA module 2, described insulation slide block 4 is slidably connected with insulating slide 3, the described fixing peace of welding sheet 7 that breaks off relations
Being contained on insulation slide block 4 and an electrode tip copper strips 9 of break off relations welding sheet 7 and nested WFTA module 2 is flexible coupling, described unhook is welded
Sheet 7 welds together with a pin 5 low temperature soldering 8 of varistor, and the another one pin 5 of described varistor is with embedding
Another electrode tip of set of modules 2 is connected, and described compression spring 6 is positioned at insulating slide 3 and the length direction of compression spring 6
Identical with the length direction of insulating slide 3, one end of described compression spring 6 is fixing with one end of insulating slide 3 to be connected, described pressure
The other end of contracting spring 6 is fixing with insulation slide block 4 to be connected.
Further, described insulating slide 3 be the cross section of strip groove-like and insulating slide 3 be rectangle, described absolutely
The top of edge slideway 3 recess sidewall arrange oriented notch extend flange 14, described insulation slide block 4 is cuboid, described absolutely
The bottom surface of edge slide block 4 is slidably connected with the bottom land of insulating slide 3, the end face of described insulation slide block 4 and insulating slide 3 upper flange 14
Bottom surface be slidably connected.
Further, also including an eradication edge rod member 10 in described nested WFTA module 2, one end of described insulation rod member 10 is with exhausted
