Embodiment Construction
[0031] Referring to Fig. 1, Fig. 2 and Fig. 8, according to a preferred embodiment provided by the present invention, it includes a housing 1, a piezoresistor 2 installed in the housing 1 and a piezoresistor 2 connected with the piezoresistor 2 An upper pin 3 electrically connected to a lower pin 4 electrically connected to the piezoresistor 2 draws a heating pole 51 from the surface of an electrode 21 of the piezoresistor 2, and the heating pole 51 One end 52 of one end 52 is wound into a spiral shape and welded on the surface of the electrode 21 of the varistor 2, one end of the lower pin 4 is also wound into a spiral shape and welded on the surface of the other electrode 22 of the varistor 2, The other end protrudes from the housing 1 to form a connecting pin. Wind the welding end of the heating electrode 51 and the lower pin 4 and the piezoresistor 2 into a spiral shape, so as to increase the welding surface with the piezoresistor 2, increase the diffusion area, and improv...
