Embodiment
Referring to Fig. 1, 3, 4, 9, it has an explosion-resistant enclosure (1) and is located at the inner box (2) in this explosion-resistant enclosure, two Zinc-oxide piezoresistors (3 are housed in described inner box, 4) and one gas discharge tube (5), also be provided with a two rake pin shape metallic spring (6) in described inner box, one end (5-1) welding of the afterbody of described pair of rake pin shape metallic spring and described gas discharge tube, the other end of described gas discharge tube (5-2) is as with geodesic PE, holding the pin joined to draw, two rake pin ends of described pair of rake pin shape metallic spring are respectively by an end (3-1 of a low temperature solder joint and two Zinc-oxide piezoresistors, 4-1) welding, thereby realize connecting of described two Zinc-oxide piezoresistor one ends and described gas discharge tube one end, the other end (the 3-2 of described two Zinc-oxide piezoresistors, 4-2) respectively as with zero line N end and phase line L, holding the pin joined to draw.
Referring to Fig. 5,6,7,8, also be provided with a sensitive switch for remote alarm in described inner box (2), this sensitive switch is comprised of the common terminal (8) and two shell fragments (9) that are arranged on two rake pin belows of described pair of rake pin shape metallic spring and the contact block (7) be located at respectively on two rake pins of described pair of rake pin shape metallic spring, and described contact block (7) is connected on described pair of rake pin shape metallic spring (6) by a button-shaped structure.Described button-shaped structure forms by being located at the button (7-1) on contact block (7) and being located at the described pair of button hole (6-1) on rake pin shape metallic spring rake pin, and described contact block (7) stretches into behind button hole (6-1) half-twist again by its button (7-1) and is connected on two rake pin shape metallic springs.Described common terminal (8) and two shell fragments (9) are drawn by three pins (11).
