Abstract
The utility model relates to a lightning protection device of electronic products, which comprises an insulation core support, a zinc oxide piezoresistor and an electrode, and is characterized in that the electrode is derived from the zinc oxide piezoresistor; an elastic reed and the electrode that is derived from the zinc oxide piezoresistor are welded through low temperature soldering tin; a moving contact of a contact switch is adjacent to the elastic reed; a static contact of the contact switch is arranged on a side that is different from the side on which the moving contact of the contact switch is arranged; the moving contact and the static contact are provided with an outgoing line respectively; the elastic reed is provided with an outgoing electrode. As the zinc oxide piezoresistor of the utility model is welded with the elastic reed through the low temperature soldering tin, in case that the temperature raises due to lightning, the low temperature soldering tin melts, the elastic reed flicks, and circuit is disconnected and an alarming system is put through, then the temperature of the zinc oxide piezoresistor that loses current path begins to fall, thus achieving the target of explosion-protection and flame retarding.
Description
Technical field
The utility model relates to a kind of lightning protection device of electronic product.
Background technology
The used zinc oxide varistor spare of existing electronic product lightning protection device, when thunderbolt generation damage took place, easily burn through burning brought great hidden danger to safety.
Summary of the invention
The purpose of this utility model; be that a kind of lightning protection device of electronic product safely and effectively will be provided; it is on the basis of original Zinc-oxide piezoresistor; increase temperature dropout servicing unit; when the generation lightning discharge makes the piezo-resistance temperature be elevated to the burn through limit point; the auxiliary tripping device divides deenergizing, reaches the purpose of security protection.
The lightning protection device of a kind of electronic product described in the utility model; it comprises insulation core body support, Zinc-oxide piezoresistor, electrode; it is characterized in that: draw an electrode at Zinc-oxide piezoresistor; there is the extraction electrode of an elastic spring and Zinc-oxide piezoresistor to connect with the eutectic welding soldering; next-door neighbour's elastic spring has the moving contact of a contact-making switch; the opposite side of contact beginning moving contact is the fixed contact of contact beginning; moving contact and fixed contact respectively have a lead-out wire, and elastic spring has an extraction electrode.
The utility model is provided with shell.
The beneficial effects of the utility model are, owing on Zinc-oxide piezoresistor, connect elastic spring with the eutectic welding soldering, when making that running into the thunderbolt temperature raises, the low temperature melts soldering tin, elastic spring flicks, and divides deenergizing, and connects warning system, the Zinc-oxide piezoresistor temperature that loses current path begins to reduce, and reaches explosion-proof fire-retardant purpose.
Description of drawings
Fig. 1 is that the utility model elastic spring and Zinc-oxide piezoresistor are connected circuit diagram.
Fig. 2 is the utility model elastic spring disjunction circuit diagram.
Fig. 3 is the utility model schematic appearance.
Among the figure: 1. insulation core body support, 2. electrode, 3. Zinc-oxide piezoresistor extraction electrode, 4. elastic spring, 5. low temperature scolding tin, 6. moving contact, 7. fixed contact, 8. moving contact lead-out wire, the 9. quiet lead-out wire of lifting one's head, 10. elastic spring extraction electrode, 11. shells.
Embodiment
The lightning protection device of a kind of electronic product described in the utility model; as Fig. 1; Fig. 2 and shown in Figure 3; it comprises insulation core body support 1; Zinc-oxide piezoresistor is contained in the insulation core body of sealing; electrode 2; Zinc-oxide piezoresistor is drawn an electrode 3; there are an elastic spring 4 and the extraction electrode 3 usefulness low temperature scolding tin 5 of Zinc-oxide piezoresistor to weld; next-door neighbour's elastic spring has the moving contact 6 of a contact-making switch; the opposite side of contact-making switch moving contact 6 is fixed contacts 7 of contact beginning; moving contact 6 and fixed contact 7 respectively have a lead-out wire; be respectively 8 and 9, elastic spring has an extraction electrode 10.The utility model is provided with shell 11.When product is made, elastic spring 4 is pressed to the extraction electrode 3 of Zinc-oxide piezoresistor, and connect with the eutectic welding soldering.The current path of Zinc-oxide piezoresistor is by 2 to 3 to 5 to 4 to 10 at this moment.When running into thunder and lightning, when Zinc-oxide piezoresistor produces high temperature, the low temperature melts soldering tin, elastic spring 4 bullets are to adjacent moving contact 6, make moving contact 6 contact the connection warning system with adjacent fixed contact 7; Because the low temperature melts soldering tin, elastic spring flicks, and makes the Zinc-oxide piezoresistor temperature that loses current path reduce, and reaches explosion-proof fire-retardant effect.
Claims (2)
